Problems solved by technology

First of all, the heat resistance and weather resistance of traditional plastic woven bags are poor, and the service life is short; secondly, calcium carbonate is often used as filler in traditional crafts, although calcium carbonate can comprehensively improve the stability, fluidity and toughness of plastic woven bags , Rigidity, but in the process of processing calcium carbonate will appear dust pollution, its extinction will cause the appearance of the woven bag to be dull, and its hardness is relatively high, which will cause damage to the equipment used in subsequent processing, so a filler that replaces calcium carbonate is needed agent, and develop a new production process

Abstract

The invention relates to a novel production process of plastic woven bag. The production process comprises the following steps of: mixing preparation of raw materials including a component A that comprises the raw materials of polypropylene, maleic anhydride, styrene, xylene and dicumyl peroxide with a weight ratio of the polypropylene to the maleic anhydride to the styrene being 25:1:1, and a component B that comprises the raw materials of polypropylene, polyethylene, talcum powder, a dispersing agent and a light stabilizer, wherein the component A and the component B are sent into a drying stirrer according to a weight ratio of 1:20, the drying temperature is 30-35 DEG C, and the drying time is 15-20min; extrusion of the raw materials: placing the above raw materials in a melting machineat 240-250 DEG C for melting treatment, feeding the melt into an extruder, and cooling an extruded plastic film into water at 30-35 DEG C to form a solid film; and carrying out drawing, weaving and sewing. The novel production process of the plastic woven bag, provided by the invention, has the advantages of little pollution and good product performance.

Description

technical field [0001] The invention relates to the technical field of plastic weaving technology, in particular to a novel production technology of plastic weaving bags. Background technique [0002] Nowadays, plastic woven bags have become one of the indispensable items in life and production. In the plastic woven industry, plastic woven bags refer to the packaging materials used to hold various items that are drawn into fibers and woven into cloth with plastic film. It uses polypropylene and polyethylene resin as the main raw materials, adding fillers and various additives, extruding and drawing into flat filaments, and then weaving and making bags. First of all, the heat resistance and weather resistance of traditional plastic woven bags are poor, and the service life is short; secondly, calcium carbonate is often used as filler in traditional crafts, although calcium carbonate can comprehensively improve the stability, fluidity and toughness of plastic woven bags , Rig...
