Plastic track thermoplastic elastomer and preparation method thereof

Abstract

The invention discloses a plastic track thermoplastic elastomer and relates to the field of thermoplastic elastomers. The plastic track thermoplastic elastomer is composed of, by weight part, 25-35 parts of EPDM (ethylene-propylene-diene monomer), 7-13 parts of TPU (thermoplastic polyurethane), 36-44 parts of coral powder, 18-22 parts of naphthenic oil 4006, 3-5 parts of lubricant, 3-5 parts of carbonyl diamide, 1-2 parts of surfactant, 2-4 parts of iodized salt, 14-16 parts of diatomite, 2-3 parts of ultraviolet resistant agent, 2-4 parts of lithium aluminum hydride, 1-3 parts of vermiculitepowder, 2-4 parts of sodium alginate, 2-4 parts of benzalkonium, 1-3 parts of diphenylethane decabromide, 2-4 parts of magnesium hydrate and 0.5-1.5 parts of antimonous oxide. A plastic track made ofthe plastic track thermoplastic elastomer not only has the advantages of high elasticity, high strength, vibration resistance and the like, but also achieves high heat resistance and ageing resistanceas well as powerful fire resistance, thereby being long in service life; beside, the preparation method of the plastic track thermoplastic elastomer is simple and applicable to scale production.

Description

technical field [0001] The invention relates to the field of thermoplastic elastomers, more specifically, it relates to a thermoplastic elastomer for a plastic runway and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, more and more people are gradually paying attention to their health. For this reason, many cities have also built sports venues of different sizes, and generally have plastic track. The plastic runway, also known as the all-weather track and field track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls....

Problems solved by technology

And because the plastic runway will be used by a large number of people for a long time, there are also some people who like to smoke into the plastic runway with unextinguished cigarette butts, and discard the cigarette butts on the plastic runway, so it is easy to appear on the plastic runway. In severe cases, it will even cause a large area to be burned, which in turn will accelerate the damage of the plastic runway
