Preparation method of biodegradable antibacterial sole material for cotton slippers

Abstract

The preparation method of a biodegradable and antibacterial cotton slipper sole material provided by the present invention comprises component A and component B in mass ratio (2-4): 1; wherein, component A consists of the following weight ratio Ingredients: 30-50 parts of modified starch, 20-30 parts of plant fiber, 10-20 parts of starch octyl succinate, 10-20 parts of biodegradable resin, biomass-based 1,4-butane 4-6 parts of isocyanate, 3-7 parts of nano fillers, 2-4 parts of Folium Folium, 1-3 parts of honeysuckle; the component B is made of the following components by weight: 30-40 parts of xylan, 11-19 parts of mannan, 21-25 parts of polycaprolactone, 1-5 parts of compatibilizer, 1-5 parts of coupling agent, 1-5 parts of antioxidant, 2-8 parts of calcium carbonate, stearic acid 2-5 parts, glass fiber 1-5 parts, crosslinking agent 1-3 parts, foaming agent 2-7 parts, stabilizer 4-8 parts, nano-silver particles 1-3 parts. The sand and slippers sole material has simple preparation process, low cost, good elasticity, light weight, good softness, biodegradability and antibacterial properties.

Description

technical field [0001] The invention belongs to the field of daily necessities, in particular to a biodegradable and antibacterial cotton slipper sole material and a preparation method thereof. Background technique [0002] There are many types of sole materials, which are generally divided into two types: natural sole materials and synthetic sole materials. Natural sole materials include natural bottom leather, bamboo, wood, etc., and synthetic sole materials include rubber, PU materials, PVC synthetic resins, etc. The common characteristics of sole materials are wear resistance, water resistance, good elasticity, easy to fit the foot shape, and not easy to deform after being shaped. Synthetic sole materials are currently the most widely used type of shoe materials. [0003] The main components of shoe materials and shock-resistant sheets for packaging currently on the market are PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), EVA (ethylene-vinyl acetate ...

AI Technical Summary

Problems solved by technology

[0003] The main components of shoe materials and shock-resistant sheets for packaging currently on the market are PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), EVA (ethylene-vinyl acetate copolymer), rubber, etc. Petrochemical products, they are all high polymers, because of the high degree of polymerization and strong intermolecular force, the polymer chains are difficult to break and decompose, which leads to the non-degradability of existing shoe materials and shock-resistant packaging sheets, which will pollute surroundings

At the same time, petroleum is a non-renewable resource on the earth, which makes petroleum products non-renewable and costly

At the same time, cotton slippers are very easy to breed bacteria
