TPE (thermal plastic elastomer) and application thereof

Abstract

The invention relates to a TPE (thermal plastic elastomer) and application thereof, and belongs to the technical field of the macromolecular TPE. The TPE is characterized by being prepared by adding the following raw materials in parts by weight into an internal mixer to be subjected to 105-DEG C internal mixing: 90 to 110 parts of chlorinated polyethylene, 10 to 20 parts of calcium carbonate, 0.5 to 1.5 parts of cross-linking agents, 0.3 to 1.5 parts of accessory ingredients, 0.3 to 1.5 parts of zinc oxide and 1.5 to 2.1 parts of azodicarbonamide. The TPE has the characteristics of aging resistance, color change avoidance, flame-retardant performance, high tensile strength and the like, and can be applied to runway color particles, lawn color particles, lawn buffer ground pads and prefabricated runway coiled materials.

Description

technical field [0001] The invention relates to a TPE elastomer and its application, and belongs to the technical field of polymer thermoplastic elastomers. Background technique [0002] Thermoplastic elastomer is a type of elastomer that has the elasticity of rubber at room temperature and can be plasticized at high temperature. Thermoplastic elastomer has the physical and mechanical properties of vulcanized rubber and the processability of thermoplastics. It is a new type of polymer material between rubber and resin, and is often called the third-generation rubber. [0003] TPE elastomer has some defects. Its heat resistance is not as good as that of rubber. As the temperature rises, the physical properties decrease greatly, so the scope of application is limited. At the same time, the compression deformation, resilience, and durability are inferior to those of rubber, and the price is often higher than that of similar rubber. But generally speaking, the advantages of TP...

Problems solved by technology

[0004] EPDM particles used in sports venues, that is, EPDM granules, anti-aging performance, color fastness, tensile strength, flame retardancy, and elasticity cannot normally meet the needs of high-end sports venues, and the rebound rate and resistance to stretching caused by ground cracks Impact, color fading, and grain aging after one year have brought many disadvantages to sports venues. Most lawn grains are filled with black rubber grains, which are heavy and not environmentally friendly.
