NOVELTY - High wear-resistant plastic cement track colloidal particle comprises 37.60-38.60 wt.% thermoplastic polyurethane, 14.40-15.40 wt.% organosilicone resin, 7.40-8.40 wt.% foaming agent, 1.30-1.70 wt.% coloring agent, 1.80-2.20 wt.% double-sulfur bond cross-linking agent, 0.20-0.40 wt.% antioxidant, 0.20-0.40 wt.% anti-aging agent, 0.20-0.40 wt.% initiator, 0.20-0.40 wt.% vulcanizing agent, and remaining amount of composite filler. USE - Used as high wear-resistant plastic cement track colloidal particle. ADVANTAGE - The colloidal particle: enhances the elastic performance of the high wear-resistant plastic runway colloidal particles after being heated and cooled; avoids the rubber particles from becoming brittle and hard; prolongs the service life of the plastic runway; uses thermoplastic polyurethane and organosilicone resin for compounding work; uses double-sulfur bond cross-linking agent to process the thermoplastic polyurethane, which can enhance the elasticity of the colloidal particles, hardness and self-repairing performance; uses nano silicon dioxide and bamboo fiber of composite filler, nano silicon dioxide, which enters into the intercalation of hexagonal boron nitride and graphene oxide; and enhances the safety and stability of the colloidal particles after heating.
