Problems solved by technology

The traditional woven bag production materials are made of polypropylene, polyethylene and masterbatch with dry mixing. The produced plastic woven bags are prone to aging, peeling, breaking and crushing under high temperature and ultraviolet radiation in summer. It is easy to seep water in, which not only affects the items in the plastic bag, but also affects the use effect of the plastic woven bag.

Abstract

The invention relates to the technical field of woven bags, and especially relates to a moisture-proof plastic woven bag. The moisture-proof plastic woven bag comprises, by mass, 10-20 parts of an ethylene-vinyl acetate copolymer, 10-15 parts of nano-sulfobetaine, 5-10 parts of bentonite, 5-10 parts of dimethylaminoethyl acrylate, 3-8 parts of tetraethoxysilane, 3-8 parts of nanometer calcium carbonate, 10-20 parts of low-density polyethylene and 10-15 parts of polypropylene particles. The moisture-proof plastic woven bag adopting the above components is not prone to aging, peeling, breaking and crushing, and is not prone to be seeped in a humid environment, so that the service life of the plastic woven bag is prolonged; and the moisture-proof plastic woven bag also has the advantages of no environment pollution, low component cost, and easiness in production.

Description

technical field [0001] The invention relates to the technical field of woven bags, in particular to a moisture-proof plastic woven bag. Background technique [0002] The main raw materials of plastic woven bags are polypropylene and polyethylene. At present, it is widely used in cement, fertilizer, chemical industry and other fields. Its main production process is to use raw materials to extrude film, wire drawing, winding, circular weaving, printing, cutting, sewing, and finally obtain the finished plastic woven bag. The traditional woven bag production materials are made of polypropylene, polyethylene and masterbatch with dry mixing. The produced plastic woven bags are prone to aging, peeling, breaking and crushing under high temperature and ultraviolet radiation in summer. It is easy to seep water in, which not only affects the items in the plastic bag, but also affects the use effect of the plastic woven bag. [0003] Chinese invention patent CN 109021355 A discloses ...
