Problems solved by technology

[0002] Plastic woven bags are divided into polypropylene bags and polyethylene bags according to the main material composition. The production process is to use plastic raw materials to extrude film, cut, and unidirectionally stretch into flat wire, and then weave warp and weft to obtain the product, which is generally called a woven bag. The packaging bag made of polypropylene flat wire produced by traditional technology has poor weather resistance. Problems such as hardening, brittleness, peeling, peeling, and fracture are prone to occur in winter in the north. In the south, due to high temperature, strong light, and strong ultraviolet penetration in summer, it is easy to cause aging, corrosion, poor toughness, and low strength of woven bags. Short lifespan and other issues waste resources and pollute the environment, so it is necessary to study how to improve the weather resistance of plastic woven bag materials

Abstract

The invention belongs to the technical field of materials for plastic woven bags, and in particular relates to a preparation method of filaments for weather-resistant plastic woven bags. The method comprises the steps of preparing raw materials, preparing mixed powder, carrying out melt filtration on the raw materials, extruding to obtain a film, cooling with water, splitting into filaments, drawing the filaments and winding. Compared with the prior art, the preparation method provided by the invention has the advantages that the physical properties of the obtained woven bags can be better improved by proportioning the raw materials with different molecular weights; the compatibility of the materials can be improved due to the use of silane-grafted polyethylene; wollastonite powder is processed, and other raw materials are cooperatively used, so that the weather resistance of the material can be improved; in outdoor atmospheric exposure tests, the physical properties are maintained well; the plastic woven bags made by using the filaments have better oxidation resistance and anti-sunburn property, and are solid, durable and long in service life.
