Abstract
The invention discloses a coating method of a woven bag. The coating method comprises the following steps of: firstly weaving warps and wefts made of fiber materials into a barrel-shaped fiber weaving layer on a circular weaving machine; then spraying paint prepared on site on the inner side of the weaving layer to form lining, wherein the paint comprises the following components in parts by weight: 16-20 parts of ethylene-vinyl acetate copolymer, 26-35 parts of polyving akohol, 30-45 parts of isocyanate, 20-35 parts of polyether glycol and 10-20 parts of diethyl methyl benzene diamine; and drying and obtaining a woven bag product with internal spraying.
Description
Technical field
The present invention relates to a kind of painting method, specifically, relate to a kind of painting method of woven bag.
Background technology
Woven bag is the packing of the widely used conveying powdered products of industry such as industry, agricultural, building.Woven bag is normally formed by interlacing silk braiding, has small slit in the crossover sites of braided wires.In order to remedy this defective, people once were used for the woven bag finish coat with poly-vinyl resin.This coating is aging coming off easily, and also not wear-resisting, service life is shorter.The manufacture method of this kind finish coat woven bag is: first weaving fiber tubular article on circular weaving machine, then coated with resins is joined in the extruder, and through extruder extruding and hot melting film, be coated to the outside face of knitted cylindrical thing and become product.This production method needs more production facilities, and energy resource consumption is larger, and factory building is also had requirement; Simultaneously the health of environment and operating personal is all brought adverse effect.
Summary of the invention
The technical problem to be solved in the present invention is the deficiency that overcomes existing woven bag surface coating process, and a kind of wear-resisting, withstanding corrosion, high, the long service life of intensity are provided, and production technology is simple simultaneously, efficient is high, free of contamination woven bag painting method.
The woven bag of manufacturing of the present invention is made of fiber braiding layer and inside liner, and improvements are that described inside liner forms lining by spraying method in fiber braiding layer inside.
Described fiber braiding layer is take polypropylene (English name pp) as primary raw material, through extruding, stretch the formation flat filament, weaves, works out through circular weaving machine again.The thickness of described inside liner is 0.1～0.6mm.
Woven bag method for making of the present invention is: warp and the parallel that will adopt lamination coating to make on circular weaving machine first are woven into the tubular fiber braiding layer, then spray painting is formed liner in the braid inboard, described coating comprises following component (mass parts) and content:
Ethylene-vinyl acetate copolymer 16-20
Polyvinyl alcohol 26-35
Isocyanates 30-45
Polyether Glycols 20-35
Diethyl toluene diamine 10-20.
After the above-mentioned coating component prepared abundant mixing at the scene, in temperature 45 C～60 ℃, under the condition of pressure 10～15MPa, utilize spray gun spraying in the inboard of fiber braiding layer, form lining coating, after the drying, product.
Above-mentioned warp and parallel are to adopt acrylic resin and are that to add weight portion be 0.4 part antioxidant 1010, the ultraviolet absorbent UV-327 that weight portion is 0.5 part, the auxiliary antioxidant DLTP that weight portion is 0.6 part for 100 parts acrylic resin according to weight portion; The compound that obtains is stretched by extruder and draw bench; The polyacrylic fibres that rolling forms, it has high strength, high abrasion, good toughness, the premium properties such as lightweight.The coating of above-mentioned spraying is a kind of novel environment friendly material, it is inboard to be sprayed on the woven bag tubular article, have coating densification, continuous, jointless characteristics, withstanding corrosion, high temperature resistant, shock resistance, be difficult for aging coming off, and the fully moisture in the air-isolation and the infiltration of oxygen, especially be fit to carry chemical frbre industry raw material, agrochemical, the pulverulent materials such as construction cement.Woven bag painting method provided by the invention has improved prior art and has used extruder at woven bag outside face coated plastic film, then utilizes the again complicated technology of coated plastic film of another surface that bag overturning machine translates into woven bag.Its objective is that a kind of raw materials consumption is provided is few, cost is low, and is lightweight, woven bag manufacture method of long service life and products thereof.Not only technique is simple, equipment investment is few for the method, production efficiency is high, and is conducive to environmental protection.
The specific embodiment
Further specify the present invention below by embodiment.
