▎ 摘　　要

NOVELTY - Degradable, high-strength and wear-resistant polyvinyl chloride foam material comprises 40 pts. wt. polyvinyl chloride, 25 pts. wt. poly(butylene adipate-co-terephthalate), 20 pts. wt. polylactic acid, 25 pts. wt. thermoplastic starch, 1-5 pts. wt. composite wear-resistant additive, 6 pts. wt. plasticizers, 3 pts. wt. alkyl glycoside foaming agents, 6 pts. wt. fillers, 3 pts. wt. titanium dioxide, 4 pts. wt. calcium zinc stabilizer, 0.4 pts. wt. lubricant, 0.15 pts. wt. paraffin, 0.2 pts. wt. ADR chain extender, 0.8 pts. wt. crosslinking agent, 0-3 pts. wt. azodicarbonamide foaming agent. USE - Degradable, high-strength and wear-resistant polyvinyl chloride foam material. ADVANTAGE - The material greatly increases the proportion of degradable components while retaining the foaming function of the product, has scientific and reasonable composition, the degradable component has good compatibility with the foam matrix, and the product has degradability, which greatly improves the economic and environmental benefits. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing degradable, high-strength and wear-resistant polyvinyl chloride foam material, comprising adding raw materials into the internal mixer and mixing, and subjecting blended product to hot and cold compression molding.
