Abstract

The invention discloses high-wear-resistance plastic runway colloidal particles and a preparation method thereof, and particularly relates to the technical field of plastic runways, and the high-wear-resistance plastic runway colloidal particles comprise thermoplastic polyurethane, organic silicon resin, a foaming agent, a coloring agent, a disulfide bond cross-linking agent, an antioxidant, an anti-aging agent, an initiator, a vulcanizing agent and a composite filler. The elastic property of the high-wear-resistance plastic runway colloidal particles after being heated and cooled can be effectively enhanced, the colloidal particles are prevented from becoming brittle and hard, and the service life of the plastic runway is prolonged; the thermoplastic polyurethane and the organic silicon resin are compounded, and the thermoplastic polyurethane is treated by adopting the disulfide bond cross-linking agent, so that the elasticity, hardness and self-repairing performance of the colloidal particles can be effectively enhanced; nano silicon dioxide and bamboo fibers of the composite filler enter an intercalation of hexagonal boron nitride and graphene oxide, and nano titanium dioxide and manganese dioxide cooperate with each other, so that the safety and stability of the colloidal particles after being heated can be effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of plastic track, more specifically, the invention relates to a high wear-resistant plastic track particle and a preparation method thereof. Background technique [0002] Plastic track, also known as 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 track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to the development of athletes' speed and technology, which can effectively improve sports performance and reduce the rate of falls. The plastic runway has certain elasticity, color, anti-ultraviolet ability and aging resistance. The runway rubber particles are mostly high-elastic EPDM and PU particles, mainly in color, with a particle size of 8-24 (mesh), and a...
