Introduction

As an important polymer material, polyurethane elastomer plays an increasingly important role in industrial production and daily life. However, with the continuous expansion of application fields, the performance requirements for polyurethane elastomers are also increasing. To meet these needs, researchers continue to explore new modification methods and additives. 2,2,4-trimethyl-2-silicon morpholine (TMSM) as a novel chemical modifier has shown great potential in the production of polyurethane elastomers.

This article aims to comprehensively explore the key role of TMSM in the production of polyurethane elastomers, focusing on its improvement of product physical performance and processing efficiency. By analyzing the chemical characteristics, mechanism of action and practical application effects of TMSM, we will gain an in-depth understanding of how this compound optimizes the performance of polyurethane elastomers and provide new ideas for research and development in related fields.

I. Chemical characteristics and mechanism of 2,2,4-trimethyl-2-silicon morphine

2,2,4-trimethyl-2-silicon morphine (TMSM) is an organic compound containing silicon elements. Its molecular structure is unique and combines the characteristics of silane groups and morphine rings. This structure imparts excellent chemical stability and reactivity to TMSM, making it have wide application prospects in the field of polymer modification.

The molecular structure of TMSM can be described as a central silicon atom connecting three methyl groups and a morphine ring. This structure not only provides a good steric hindrance effect, but also imparts a certain polarity to the molecule. The presence of silicon atoms gives TMSM excellent heat resistance and chemical stability, while the morphine ring provides good reactive sites. This unique structural combination allows TMSM to play multiple roles in the synthesis of polyurethane elastomers.

In the synthesis of polyurethane elastomers, TMSM mainly passes twoThese mechanisms play a role: first, as a chain growth agent, participate in the formation of polyurethane chains; second, as a crosslinking agent, promote the formation of three-dimensional network structures. The silicon atoms in TMSM can react with isocyanate groups to form stable silicon-nitrogen bonds, thereby effectively controlling the progress of polymerization. At the same time, the morphine ring in TMSM can react with the active groups in the polyurethane molecular chain to form crosslinking points and enhance the mechanical properties of the material.

In addition, TMSM can also adjust the molecular weight distribution of the polymer through its steric hindrance effect and improve the processing performance of the material. The methyl groups in its molecular structure can effectively inhibit the occurrence of side reactions and improve the selectivity of the reaction, thereby obtaining polyurethane elastomer products with better performance.

2. Improvement of physical properties of TMSM on polyurethane elastomers

The introduction of TMSM has significantly improved the physical properties of polyurethane elastomers, mainly reflected in three aspects: mechanical properties, thermal stability and chemical resistance. In terms of mechanical properties, the addition of TMSM has significantly improved the tensile strength, elongation of break and tear strength of the polyurethane elastomer. Studies have shown that the tensile strength of polyurethane elastomers with an appropriate amount of TMSM can be increased by 20-30%, the elongation of breaking by 15-25%, and the tear strength can be increased by 10-20%. These improvements are mainly attributed to the uniformly dispersed and efficient crosslinking network formed by TMSM in polymer matrix.

In terms of thermal stability, the silicon content of TMSM imparts excellent thermal stability to the polyurethane elastomer. Through thermogravimetric analysis (TGA) test, it was found that the initial decomposition temperature of polyurethane elastomers with TMSM increased by 20-30°C and the large decomposition temperature increased by 15-25°C. This enhanced thermal stability allows the material to maintain its performance at higher temperatures, expanding the application range of polyurethane elastomers.

In terms of chemical resistance, the introduction of TMSM has significantly enhanced the resistance of polyurethane elastomers to chemical substances such as acids, alkalis, and oils. Experimental data show that the swelling rate of polyurethane elastomers modified by TMSM in acid and alkali solutions was reduced by 30-40%, and the mass loss in oil media was reduced by 20-30%. This improvement in chemical resistance is mainly due to the stability of silicon oxygen bonds in TMSM molecules and the hydrophobicity of the morphine ring.

In order to more intuitively demonstrate the improvement of TMSM on the physical properties of polyurethane elastomers, we have compiled the following comparison data table:

These data clearly demonstrate the significant effect of TMSM in improving the physical properties of polyurethane elastomers, providing strong support for the application of materials in harsh environments.

3. The role of TMSM in the optimization of processing efficiency of polyurethane elastomers

TMSM not only performs well in improving the physical properties of polyurethane elastomers, but also plays an important role in optimizing processing efficiency. First, the introduction of TMSM significantly improved the processing fluidity of polyurethane elastomers. Because the silane groups in its molecular structure can reduce the viscosity of the polymer melt, the material is easier to flow and mold during processing. Experimental data show that after the addition of TMSM, the melt flow index (MFI) of polyurethane elastomer increased by 15-25%, which directly led to an improvement in processing efficiency.

In terms of molding process, the addition of TMSM makes it easier to release the polyurethane elastomer, reducing defects on the surface of the product. This is mainly attributed to the lubrication effect of methyl groups in the TMSM molecule, which reduces the friction coefficient between the material and the mold surface. Actual production data show that the release time of polyurethane elastomers modified with TMSM was shortened by 20-30%, and the product pass rate was increased by 5-10%.

TMSM's optimization of polyurethane elastomer processing efficiency is also reflected in the following aspects:

1. Reduce processing temperature: Because TMSM improves material flow, processing temperature can be reduced by 10%-15℃, thereby saving energy consumption.
2. Shortening curing time: The catalytic action of TMSM shortens the curing time of polyurethane elastomers by 15-20%, improving production efficiency.
3. Improving surface quality: The addition of TMSM makes the surface of the product smoother and reduces the after-treatment process.
4. Improving equipment utilization: Due to the improvement of processing efficiency, more products can be produced within the same time, which improves equipment utilization.

In order to more intuitively demonstrate the optimization effect of TMSM on processing efficiency, we have compiled the following comparison data table:

These data fully illustrate the significant role of TMSM in optimizing the processing efficiency of polyurethane elastomers, and bring considerable economic benefits to manufacturers.
