Abstract
A kind of coating procedure of woven bag inside, comprise the following steps: first on circular loom, the warp adopting fibrous material to make and parallel are woven into tubular fiber braiding layer, then the spray painting of extemporaneous preparation is formed liner inside braid, described coating comprises following component (parts by mass): ethylene-vinyl acetate copolymer 26-30; Polyvinyl alcohol 36-45; Isocyanates 16-25; Polyether Glycols 26-35; Diethyl toluene diamine 15-28; Namely the woven bag product of interior spraying is obtained after drying.
Description
Technical field
The present invention relates to a kind of painting method, specifically, relate to a kind of coating procedure of woven bag inside.
Background technology
Woven bag is the packaging of the widely used conveying powdered product of industry such as industry, agricultural, building.Woven bag is normally woven by interlacing silk and forms, and has small gap in the crossover sites of braided wires.In order to make up this defect, polyvinyl resin was once used for woven bag face coat by people.This coating is easily aging to come off, and also not wear-resisting, service life is shorter.The manufacture method of this kind of face coat woven bag is: first weaving fiber tubular article on circular loom, then joins in extruder by coated with resins, through extruder extruding and hot melting film, be coated to the outer surface of knitted cylindrical thing and become product.This production method needs more production equipment, and energy resource consumption is comparatively large, also has requirement to factory building; All adverse effect is brought to the health of environment and operating personnel simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is the deficiency overcoming existing woven bag surface coating process, provide a kind of wear-resisting, corrosion-resistant, intensity is high, long service life, production technology is simple simultaneously, efficiency is high, free of contamination woven bag painting method.
The woven bag of manufacture of the present invention is made up of fiber braiding layer and inner liner, and improvements are that described inner liner forms lining by spraying method in fiber braiding layer inside.
Described fiber braiding layer is with polypropylene (English name pp) for main raw material, through extruding, stretching formation flat filament, then weaves through circular loom, works out.The thickness of described inner liner is 0.1 ~ 0.6mm.
Woven bag preparation method of the present invention is: first on circular loom, the warp adopting fibrous material to make and parallel are woven into tubular fiber braiding layer, then spray painting is formed liner inside braid, described coating comprises following component (parts by mass) and content:
Ethylene-vinyl acetate copolymer 26-30
Polyvinyl alcohol 36-45
Isocyanates 16-25
Polyether Glycols 26-35
Diethyl toluene diamine 15-28.
After above-mentioned coating component being prepared at the scene fully mixing, in temperature 45 C ~ 60 DEG C, under the condition of pressure 10 ~ 15MPa, utilize spray gun spraying in the inner side of fiber braiding layer, form lining coating, after drying, product.
Above-mentioned warp and parallel are adopt acrylic resin and the auxiliary antioxidant DLTP that is 0.6 part according to the acrylic resin that weight portion the is 100 parts ultra-violet absorber UV-327 that to add weight portion be antioxidant 1010, the weight portion of 0.4 part is 0.5 part, weight portion; The mixture obtained is stretched by extruder and wire drawing machine; The polyacrylic fibres of rolling, 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-friendlymaterial material, be sprayed on inside woven bag tubular article, there is coating densification, continuous, jointless feature, corrosion-resistant, high temperature resistant, shock resistance, not easily agingly to come off, and can the infiltration of moisture in completely isolated air and oxygen, especially conveying chemical industry raw material is applicable to, agrochemical, the pulverulent materials such as building building cement.Woven bag painting method provided by the invention improves prior art and uses extruder at woven bag outer surface coated plastic film, the complicated technology of another surface then utilizing bag overturning machine to translate into woven bag coated plastic film again.Its objective is that to provide a kind of raw materials consumption few, cost is low, 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.
Detailed description of the invention
The present invention is further illustrated below by embodiment.
