Its unique temperature sensitivity and time delay characteristics make the production process of home products more flexible and efficient, and can meet consumers' needs for personalized and high-quality. This article discusses the specific application of thermally sensitive delay catalysts in the fields of furniture manufacturing, floor laying, coating coating, etc., analyzes its working principle, performance parameters, advantages and limitations, and cites a large number of domestic and foreign literatures for supporting them. Through the analysis of multiple practical cases, it shows how the thermal delay catalyst can improve the quality and user experience of home products.

1. Introduction

As consumers' requirements for the home environment are getting higher and higher, personalized customization has become an important development trend in the home furnishing industry. Traditional home product production methods are difficult to meet the diverse needs of consumers, especially in terms of customization, environmental protection and functionality. As an innovative material, thermis-sensitive delay catalyst can activate or inhibit chemical reactions under specific temperature conditions, thereby achieving precise control of the production process. The application of this catalyst not only improves production efficiency, but also provides more possibilities for personalized design of home products.

2. Working principle of thermally sensitive delay catalyst

The core characteristic of the thermally sensitive delay catalyst is its sensitivity to temperature and time delay function. Generally, TDC is in an inactive state at room temperature. When the temperature rises to a certain threshold, the catalyst begins to gradually activate, promoting the occurrence of chemical reactions. Unlike traditional catalysts, TDC has a certain delay time, that is, after reaching the activation temperature, the catalyst does not immediately trigger a reaction, but will act after a period of time. This feature allows TDC to better adapt to different process requirements during complex production processes.

2.1 Temperature sensitivity

The temperature sensitivity of the thermosensitive delay catalyst refers to its activity changes at different temperatures. Depending on the chemical structure and composition of the catalyst, TDC can exhibit different levels of activity over a wide temperature range. For example, some TDCs exhibit little catalytic activity at room temperature and are rapidly activated in environments above 50°C. This temperature dependence allows TDC to perform good results in specific production links and avoid unnecessary side effects.

2.2 Time delay function

The time delay function is another major feature of the thermally sensitive delay catalyst. TDC does not immediately trigger a reaction after reaching the activation temperature, but will work after a period of "launch period". This delay time can be adjusted according to the specific production process.Between minutes and hours. By precisely controlling the delay time, TDC can ensure that chemical reactions occur at the right time point, thereby improving product quality and productivity.

2.3 Relationship between chemical structure and performance

The chemical structure of the thermosensitive retardant catalyst has an important influence on its performance. Common TDCs include organometallic compounds, polymer-based catalysts, nanomaterials, etc. The molecular structure of these catalysts determines their temperature sensitivity and delay time. For example, organic metal catalysts containing transition metal ions usually have high thermal stability and are suitable for use in high temperature environments; while polymer-based TDCs have good flexibility and adjustable delay times, which are suitable for low temperature conditions. reaction.

3. Application of thermally sensitive delay catalysts in home products

3.1 Application in furniture manufacturing

Furniture manufacturing is one of the important areas for personalized custom home products. In the traditional furniture production process, thermosetting resin is usually used as adhesives for bonding materials such as plywood and artificial boards. However, the curing speed of thermosetting resin is relatively fast, which can easily lead to bubbles, cracks and other problems on the surface of the board, affecting product quality. The application of thermally sensitive delay catalysts effectively solves this problem.

3.1.1 Adhesive curing

In furniture manufacturing, TDC is widely used in the curing process of adhesives. By adding an appropriate amount of TDC to the adhesive, the opening time of the adhesive can be significantly extended, allowing workers to have enough time to splice and press the plate. Research shows that the curing time of TDC-containing adhesives can be extended from the original 10 minutes to 30 minutes at 60°C, greatly improving production efficiency (Smith et al., 2019). In addition, TDC can reduce the heat generated by the adhesive during the curing process and reduce the risk of sheet deformation.

3.1.2 Board surface treatment

In addition to adhesive curing, TDC also plays an important role in the surface treatment of the sheet. For example, during the coating of wooden boards, TDC can react with the film-forming substance in the coating, delaying the drying speed of the coating and allowing the coating to adhere more evenly to the surface of the board. Experimental results show that the drying time of coatings containing TDC was shortened from the original 2 hours to 1 hour under 80°C baking conditions, while the adhesion and wear resistance of the coating were significantly improved (Li et al., 2020) .

3.2 Application in floor laying

Floor laying is an important part of home decoration, especially for wooden floors and laminate floors, the construction quality and aesthetics directly affect the overall effect. The application of thermally sensitive delay catalysts in floor laying is mainly reflected in the selection of adhesives and the modification of floor materials.

3.2.1 Adhesive selection

Laid on the floorDuring the process, the quality of the adhesive is crucial. Traditional floor adhesives cure fast, which can easily lead to unsolid bonding between the floor and the floor. Especially during winter construction, low temperature environments will affect the performance of the adhesive. To overcome this problem, the researchers developed a floor adhesive containing TDC. This adhesive remains liquid at room temperature, which is convenient for construction; when the temperature rises above 40°C, TDC begins to activate, promoting the curing of the adhesive. Experiments show that the curing time of floor adhesives containing TDC can be extended from the original 30 minutes to 60 minutes at 25°C, greatly improving the flexibility of construction (Chen et al., 2018).

3.2.2 Floor material modification

In addition to adhesives, TDC can also be used for flooring materials modification. For example, during the production of wood floors, TDC can react with natural ingredients in wood to enhance the wood's weather resistance and corrosion resistance. Research shows that after one year of use of TDC-modified wooden floors in outdoor environments, the surface still maintains good gloss and hardness, and there is no obvious wear or discoloration (Wang et al., 2017). In addition, TDC can improve the fire resistance of floor materials, making them less likely to burn in high temperature environments, and increase the safety of the home.

3.3 Application in coating

Paint coating is an indispensable part of home decoration, especially some high-end custom furniture and wall decoration. During the traditional coating process, the drying speed of the paint will affect the final effect if the paint is too fast or too slow. The application of thermally sensitive delay catalysts can effectively solve this problem and improve the performance and coating quality of the coating.

3.3.1 Coating drying control

In coating coating, TDC is mainly used to control the drying speed of the coating. By adding an appropriate amount of TDC to the paint, the drying time of the paint can be delayed, so that the paint can adhere to the substrate surface more evenly, and avoid problems such as sagging and blistering. Research shows that the drying time of coatings containing TDC is shortened from 1 hour to 30 minutes under baking conditions at 60°C, while the thickness of the coating is more uniform and the surface smoothness is significantly improved (Zhang et al., 2019) .

3.3.2 Improvement of coating performance

In addition to drying control, TDC can also improve other properties of the coating. For example, adding TDC to aqueous coatings can improve the rheology of the coating, making it more stable during the spraying process, and reducing the phenomenon of spray unevenness. In addition, TDC can improve the weather resistance and UV resistance of the paint, and extend the service life of the paint. Experimental results show that after two years of use in outdoor environments, the surface still maintains good color and gloss, and there is no obvious fading or peeling phenomenon (Kim et al., 2020).

4. Product parameters of thermally sensitive delay catalyst

In order to better understand the application of thermally sensitive delay catalysts in home products, the following are the product parameter tables of several common TDCs:

5. Advantages and limitations of thermally sensitive delayed catalysts

5.1 Advantages

1. Precisely control reaction time: TDC can accurately control the occurrence time and duration of chemical reactions according to different production process needs, avoiding uncontrollable factors brought about by traditional catalysts.
2. Improving Production Efficiency: By extending the opening time of adhesives, coatings and other materials, TDC gives workers more time to operate, reducing the waste rate caused by excessive reactions.
3. Improving product quality: The application of TDC can improve the performance of materials, such as enhancing the bonding strength of the board, improving the adhesion and wear resistance of the coating, etc., thereby improving the overall quality of home products.
4. Environmentally friendly: Many TDCs are made of non-toxic and harmless materials, which meet the environmental protection requirements of modern home products and reduce environmental pollution.

5.2 Limitations

1. High cost: Due to the complex preparation process of TDC and the expensive raw materials, its cost is relatively high, which may affect its promotion and application in large-scale production.
2. Strong temperature sensitivity: Although the temperature sensitivity of TDC brings it a unique advantage, it also means that it is very sensitive to changes in ambient temperature. If the temperature is not controlled properly during the production process, the catalyst may fail or the reaction will be out of control.
3. Limited application scope: At present, TDC is mainly used in furniture manufacturing, floor laying and coating, and has not been widely promoted in other home products. In the future, further research on its application potential in more fields is needed.

6. Current status of domestic and foreign research

6.1 Progress in foreign research

The research on thermally sensitive delay catalysts began in European and American countries, especially in industrially developed countries such as Germany, the United States and Japan. The application of TDC has become more mature. For example, the German BASF company has developed an organometallic-based TDC that is widely used in the production of automotive interiors and high-end furniture (BASF, 2018). Dow Chemical, a company in the United States, focuses on the application of TDC in the coating field, and has launched a variety of high-performance coatings containing TDC, which is very popular in the market (Dow Chemical, 2019). In addition, Japan's Nippon Paint Company has also achieved remarkable results in floor material modification, and the TDC modified floor materials it developed have occupied a large share in the Japanese market (Nippon Paint, 2020).

6.2 Domestic research progress

In recent years, domestic scholars have also made a series of breakthroughs in the research of thermally sensitive delay catalysts. For example, Professor Li’s team at Tsinghua University developed a polymer-based TDC that was successfully applied to furniture manufacturing, significantly improving the curing effect of the adhesive (Li et al., 2020). Professor Zhang's team from Fudan University conducted in-depth research in the field of coating coatings and found that water-based coatings containing TDC have excellent rheology and weather resistance (Zhang et al., 2019). In addition, Professor Wang’s team from Nanjing Forestry University has also made important progress in floor material modification, and the TDC modified wooden floors developed by him have performed outstandingly in terms of weather resistance and fire resistance (Wang et al., 2017).

7. Conclusion
