Filament for vermin-proof plastic woven bag

Abstract

The invention discloses a filament for a vermin-proof plastic woven bag. The invention is characterized in that the filament is prepared from the following raw materials in parts by weight: 100 parts of polypropylene, 4-6 parts of metallocene linear low density polyethylene, 0.2-0.4 part of pyrethroid, 0.4-0.6 part of monobutyl tin oxide, 3.2-3.6 parts of ethyl dimethylaminoacrylate, 2-4 parts of chlorinated polyethylene, 1-1.5 parts of ferrocene, 0.1-0.2 part of selenium acetylacetone and 3-3.5 parts of assistant. The filament is prepared by the following steps: proportioning, melting, filtering, extruding to obtain a film, cooling with water, cutting into a filament, drawing, rolling and the like. The assistant can effectively resist aging and prevent solarization; the filament has the advantages of reasonable formula and low cost; the prepared plastic woven bag can effectively resist vermins; and the filament prolongs the service life of the packaging bag, widens the application range of the packaging bag, and is suitable for long-distance transport and object preservation.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a wire for insect-biting plastic woven bags. Background technique [0002] Plastic woven bags are divided into polypropylene bags and polyethylene bags according to the main material composition; according to the sewing method, they are divided into seamed bottom bags and seamed bottom bags. At present, it is widely used as a packaging material for fertilizers, chemical products and other items. Its main production process is to use plastic raw materials to extrude film, cut, and unidirectionally stretch into flat yarn, and then weave warp and weft to obtain products, which are generally called woven bags. The packaging bags made of polypropylene flat yarn produced by traditional technology have poor weather resistance, and are prone to problems such as hardening, brittleness, peeling, peeling, and breakage in winter in the north. In the south, due to high summer tempe...

AI Technical Summary

Problems solved by technology

The packaging bags made of polypropylene flat yarn produced by traditional technology have poor weather resistance, and are prone to problems such as hardening, brittleness, peeling, peeling, and breakage in winter in the north. Strong strength, it is easy to cause problems such as aging, corrosion, poor toughness, low strength and short service life of woven bags, which wastes resources and pollutes the environment
