Problems solved by technology

But there are still many problems: 1. The polyurethane foam formed by using a reactive foaming agent cannot meet the comprehensive requirements of low elastic coefficient, small compression deformation coefficient and high mechanical strength at the same time; 2. The cells are not uniform, making the backing plate Poor load uniformity and dispersion; 3. Not conducive to environmental protection
4. At present, the polyurethane that can be used for foaming is expensive, and the molding process is relatively complicated, so it is difficult to reproduce and produce in large quantities
The service life of the gasket is also relatively long, which can be equivalent to

Abstract

The invention discloses a high-performance thermoplastic elastomer and its application. The raw material component is based on SEBS, combined with homopolypropylene, ethylene-propylene elastomer, mineral oil, mineral filling, additives, etc. Compared with polyurethane, TPV, etc., the quality of the product is more stable and more efficient; at the same time, the appropriate compounding technology can form an interpenetrating polymer network structure between the components of the material, and its tensile strength is above 13.5MPa and its compression set capacity is less than 30%. , the present invention can be applied to the manufacture of urban traffic track gaskets, etc., and has the advantages of good shockproof performance and cushioning performance, low compression set, high mechanical strength and durability.

Description

technical field [0001] The invention discloses a high-performance thermoplastic elastomer and its application. According to the International Patent Classification (IPC), it belongs to the technical field of polymer new material manufacturing, and in particular relates to a shock-absorbing gasket for light rail, subway, and high-speed rail. Styrenic thermoplastic elastomers of similar materials and methods of making the same. Background technique [0002] The opening and operation of the "Wuhan-Guangzhou" high-speed railway means the arrival of the high-speed railway era, and many new materials (such as polyurethane and other thermoplastic elastomers) are gradually incorporated into the construction of high-speed railways to meet their special requirements for performance. The high-speed development of the high-speed rail era will inevitably induce a wide demand for raw materials, and track damping gaskets will become an inestimable part as a basic part of high-speed rail, s...
