CN103628171A - Antistatic threads for plastic woven bags - Google Patents

Abstract

The invention discloses antistatic threads for plastic woven bags. The antistatic 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, 1.2-1.4 parts of trichlorophenyl maleic amide, 0.3-0.5 part of imidacloprid, 1.2-1.5 parts of cross-linking agent TAIC, 1.3-1.5 parts of sepiolite powder, 5-6 parts of vinyl acetate, 6-8 parts of 1, 6-hexanediol diacrylate, 1-1.2 part of N-hydroxymethyl acrylamide, 0.3-0.5 part of nanocarbon and 3-3.5 parts 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 antistatic threads are simple in formula, low in cost and capable of effectively resisting static electricity and sparks generated by electrostatic charges so as to achieve the flame retardant effect. The plastic woven bags manufactured by using the threads are particularly suitable for fields such as mines and coal and can be used for avoiding fire disasters or explosion caused by sparks due to electrostatic charges.

Description

Silk for a kind of anti-static plastic braiding bags

Technical field

The present invention relates to chemical technology field, particularly silk for a kind of anti-static plastic braiding bags.

Background technology

The main raw material of plastic knitting goods is PP/PE, due to the poor electric conductivity of the plastics such as PP/PE, inflammable.From woven product production procedure, we know, it is wire-drawing process that plastic knitting goods the most easily produce static, and plastic flat fiber, in high-speed stretch, rotation, traction, friction, the whole process of coiling, all can produce higher static.Flat filament easily produces strand roller with static, dangerous during cleaning; Woven product can adsorb dusts in a large number with static, affects health and the performance of product; Also can be sticky together during printing, be difficult to separately, to printing, bring impact; Especially when packing granular material, material can not be attracted to packing material inner arm and cause waste; Maximum harm is that the spark that electrostatic charge produces can set off an explosion and fire.

Summary of the invention

The object of this invention is to provide silk for a kind of anti-static plastic braiding bags.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

Silk for a kind of anti-static plastic braiding bags, raw material by following weight portion is made by operations such as batching, melting, filtration, extruding membrane, water-cooled, sub-wire, wire drawing, rollings: polypropylene 100, linear low density polyethylene 10-12, trichlorophenyl maleic amide 1.2-1.4, Imidacloprid 0.3-0.5, crosslinking agent TAIC 1.2-1.5, sepiolite powder 1.3-1.5, vinylacetate 5-6,1,6-hexanediyl ester 6-8, N hydroxymethyl acrylamide 1-1.2, nano-sized carbon 0.3-0.5, auxiliary agent 3-3.5;

Described auxiliary agent is made by the raw material of following weight portion: clay 20-24, alum 5-6, altax 2-3, crosslinking agent TAC 2-3, antioxidant 1010 1-2, actinolite 3-4, ferrocene 2-3, morpholine 1-2,1,6 hexanediyl ester 5-7, phthalic acid ester 35-40, n-propyl gallate 3-4, green tea powder 1-2, coix seed oil 2-3, vanadium diboride 2-3, epicatechin 1-2; Preparation method sends into clay, actinolite in calcining furnace and calcine 2-3 hour at 720-740 ℃, then, takes out, and sends in the hydrochloric acid solution of 10-15% and soaks 2-3 hour, filters, and obtains filter residue, with clear water, cleans, and dries, grinds to form 400-600 order powder; Gained powder mixes with other residual components, is heated to 60-70 ℃, and stirring reaction 40-50 minute is cooling, grinds to form slurry, obtains.

Excellent effect of the present invention is: the present invention fills a prescription simply, cost is low, mix can be effectively antistatic and spark that electrostatic charge produces, reach fire-retardant effect, the Polywoven Bag of making is particularly useful for mine, coal with field, avoids causing fire or blast because electrostatic charge produces spark.

The specific embodiment
