Sisal fiber reinforcing starch environment-friendly degradable garbage bag and preparing method thereof

Abstract

The invention discloses a sisal fiber reinforcing starch environment-friendly degradable garbage bag. The sisal fiber reinforcing starch environment-friendly degradable garbage bag is prepared from, by weight, 40 parts of starch, 60 parts of sisal fiber, 80 parts of low-melting-flow-index linear low-density polyethylene resin, 20 parts of polyamide-epichlorohydrin resin, 30 parts of melamine resin, 20 parts of vinyl acetate-vinyl versatate-maleic acid ester, 25 parts of tetrabutyl titanate, 20 parts of polybutylene terephthalate, 4 parts of wood pulp, 1 part of casein, 15 parts of white carbon black, 5 parts of linseed oil seeds, 20 parts of silk fibroin, 5 parts of guanidine phosphate, 5 parts of sorbitol, 5 parts of talcum powder, 1 part of benzotriazole type ultraviolet absorbent, 5 parts of medical stone, 5 parts of sodium caseinate and 2 parts of acrylic acid starch. The invention further discloses a preparing method of the sisal fiber reinforcing starch environment-friendly degradable garbage bag. The sisal fiber reinforcing starch environment-friendly degradable garbage bag is degradable, high in mechanical strength and good in toughness, the preparing method is simple, the raw material is low in cost, and the bag is suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of garbage bags. More specifically, the present invention relates to a sisal fiber reinforced starch environment-friendly degradable garbage bag and a preparation method thereof. Background technique [0002] Garbage bags bring great convenience to millions of households, provide an important guarantee for environmental protection, and even help garbage recycling and classification. However, garbage bags are mainly made of plastic, and plastic is extracted from petroleum. It takes about 200 years for garbage bags to rot after being buried in the ground, and it seriously pollutes the soil. If it is incinerated, it will produce harmful smoke and toxic Gas, long-term pollution of the environment. Ordinary polymer plastics are difficult to degrade. Starch and fiber can improve the degradability of plastics, but their poor mechanical properties limit their applications. Contents of the invention [0003] It ...

However, garbage bags are mainly made of plastic, and plastic is extracted from petroleum. It takes about 200 years for garbage bags to rot after being buried in the ground, and it seriously pollutes the soil. If it is incinerated, it will produce harmful smoke and toxic gas, polluting the environment for a long time

Ordinary polymer plastics are difficult to degrade. Starch and fiber can improve the degradability of plastics, but their poor mechanical properties limit their applications.
