Description

A kind of silk for durable Polywoven Bag

Technical field

The present invention relates to chemical technology field, particularly a kind of durable Polywoven Bag silk.

Background technology

Polywoven Bag forms and is divided into Polypropylene Bag, Polythene Bag by main material; By method of sewing, be divided into bag at the bottom of the seam end bag, tape edge.A kind of packaging material that are widely used at present the article such as fertilizer, chemical products.Its main production is that to utilize plastic raw materials be flat filament through extrusion film, cutting, simple tension, through obtaining product through knitting device, is commonly referred to as woven bag.The packaging bag of the polypropylene flat-filament establishment that conventional art is produced, weatherability is poor, at north of china in winter, easily occur hardening, the problem such as embrittlement, demoulding, peeling, fracture, in south because summer temperature is high, illumination is strong, ultraviolet penetration power is strong, easily cause that woven bag is aging, the problem such as burn into poor toughness, intensity low service life is short, not only wasted resource but also contaminated environment.

Summary of the invention

The object of this invention is to provide a kind of durable Polywoven Bag silk.

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

A kind of silk for durable Polywoven Bag, is made by operations such as batching, melting, filtration, extruding membrane, water-cooled, sub-wire, wire drawing, rollings by the raw material of following weight portion: polypropylene 100, linear low density polyethylene 10-12, White Mineral Oil 1.2-1.5, dithiocyano-methane 0.3-0.6, Silane coupling agent KH550 1.2-1.4, nano-graphite 0.3-0.4, acrylic acid dimethylamino ethyl ester 1.2-1.5, cis-butenedioic anhydride 0.6-0.9, N hydroxymethyl acrylamide 0.4-0.6, antioxidant 1010 0.5-0.8, tri (propylene glycol) diacrylate 6-8, 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, and cost is low, and the Polywoven Bag volume of making is large, novel structure, durable, anti-skidding, bale broken not, suitable especially long distance transportation and outlet, solved packaging bag short problem in service life in prior art.

The specific embodiment

Below by instantiation, the present invention is described in detail.

Silk for a kind of durable Polywoven Bag, by following weight portion (kilogram) raw material by operations such as batching, melting, filtration, extruding membrane, water-cooled, sub-wire, wire drawing, rollings, make: polypropylene 100, linear low density polyethylene 10, White Mineral Oil 1.2, dithiocyano-methane 0.3, Silane coupling agent KH550 1.2, nano-graphite 0.3, acrylic acid dimethylamino ethyl ester 1.2, cis-butenedioic anhydride 0.6, N hydroxymethyl acrylamide 0.4, antioxidant 1010 0.5, tri (propylene glycol) diacrylate 6, auxiliary agent 3;

Described auxiliary agent by following weight portion (kilogram) raw material make: described auxiliary agent by following weight portion (kilogram) raw material make: clay 20, alum 5, altax 3, crosslinking agent TAC 2, antioxidant 1010 1, actinolite 3, ferrocene 2, morpholine 1,1,6 hexanediyl ester 5, phthalic acid ester 35, n-propyl gallate 3, green tea powder 1, coix seed oil 2, vanadium diboride 3, epicatechin 1; 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.

After tested, the flat filament that the present invention produces radially pull-off force and broadwise pull-off force is all greater than 800N/50mm, has greatly improved the TENSILE STRENGTH of flat filament, has stopped the fracture of wire problem in braiding process.
