Problems solved by technology

Foamed plastic polymer materials are petrochemical products and belong to high polymers. Due to the high degree of polymerization and strong intermolecular forces, the polymer chains are difficult to break and decompose, which makes the existing shoe materials non-degradable and pollutes. surroundings
At the same time, petroleum is a non-renewable resource on the earth, which makes petroleum products irreversible and expensive

Abstract

The invention discloses a biodegradable plastic sole material and a preparation method thereof. The biodegradable plastic sole material is prepared from the following raw material components in partsby weight: 80-100 parts of EVA aggregates, 20-30 parts of high-density polyethylene, 25-35 parts of ethylene-acrylate copolymers, 10-30 parts of ethylene-octene copolymers, 30-40 parts of modified poplar powder, 5-8 parts of activator mixture, 2-4 parts of talcum powder, 2-4 parts of foaming agent and 3-5 parts of crosslinking agent. A sole prepared according to a formula has good dampproof and waterproof effects and also has good toughness, wear resistance and slip resistance, and the plastic sole is degradable so that environment pollution can be avoided.

Description

technical field [0001] The invention relates to a sole material for slippers, in particular to a biodegradable plastic sole material and a preparation method thereof. Background technique [0002] There are many types of sole materials, generally divided into natural sole materials and synthetic sole materials. Natural base materials include natural base leather, bamboo, wood, etc., and synthetic base materials include rubber, plastic, rubber-plastic composite materials, recycled leather, elastic cardboard, etc. [0003] In life, EVA has an important position in the shoe material industry due to its non-toxic, light weight, corrosion resistance, aging resistance, high elasticity and low cost. Foamed plastic polymer materials are petrochemical products and belong to high polymers. Due to the large degree of polymerization and strong intermolecular force, the polymer chain is difficult to break and decompose, resulting in the non-degradability of existing shoe materials and p...
