Problems solved by technology

[0003] However, the heat resistance of TPE material is not as good as that of rubber, and the physical properties decrease greatly as the temperature rises, so the scope of application is limited
For example, the anti-slip mat made of TPE material has the characteristics of good elasticity, good anti-slip effect, good toughness, strong tension, recyclability and reuse. Exposure to the sun for a long time, the temperature is in a high state for a long time, its compression deformation, elastic recovery and other physical properties will be significantly reduced, which will reduce the sense of use of the floor mat and shorten the service life

Abstract

The invention relates to a TPE (Thermoplastic Elastomer) material with high temperature resistance. The TPE material is prepared from the following components in parts by weight: 80-100 parts of hydrogenated styrene-butadiene-styrene segmented copolymers, 80-100 parts of hydrogenated naphthenic oil, 15-20 parts of polypropylene, 15-20 parts of propylene-ethylene random copolymers, 100-120 parts of CaCO3, 0.5-1 part of calcium stearate, 0.1-0.2 part of 2-tertiary butyl-4,6- dimethyl phenol and 0.4-0.8 part of 2,4,6-tri-tert-butyl phenol. The TPE material disclosed by the invention has good heat resistance, physical performances such as compressive deformation and elastic recovery are not remarkably lowered due to an extremely high temperature; moreover, the TPE material is excellent in various physical performances such as surface hardness as well as tensile strength, and therefore, the TPE material is suitable for producing a ground mat paved at an outdoor production occasion, and prolonging service life of the TPE material.

Description
