Firm and durable threads for plastic woven bags

Abstract

The invention discloses firm and durable threads for plastic woven bags. The firm and durable threads are characterized by being prepared from the following raw materials in parts by weight: 100 parts of polypropylene, 10-12 parts of linear low density polyethylene, 1.2-1.5 parts of white mineral oil, 0.3-0.6 part of methane dithiocyanate, 1.2-1.4 parts of silane coupling agent KH550, 0.3-0.4 part of nano-graphite, 1.2-1.5 parts of dimethylamino ethyl acrylate, 0.6-0.9 part of maleic anhydride, 0.4-0.6 part of N-hydroxymethyl acrylamide, 0.5-0.8 part of antioxidant 10100, 6-8 parts of tripropylene glycol diacrylate and 3-3.5 part of additive by adopting the following working procedures: burdening, fusing, filtering, extruding so as to obtain membranes, carrying out water cooling, thread separation and thread drawing, winding and the like. The firm and durable threads are simple in formula and low in cost; the plastic woven bags manufactured by using the threads are large in volume, novel in structure, firm, durable, anti-skidding and unlikely to be broken; and the problem that packaging bags in the prior art are short in service life is solved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a strong and durable wire for 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 ...

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
