Abstract
The invention relates to a process for coating a polyether glycol composition in a woven bag. The process comprises the following steps: weaving warps and wefts made of fiber materials into a cylindrical fiber woven layer on a circular weaving machine; spraying coating prepared on site on the inner side of the woven layer to form lining, wherein the coating comprises the following components in part by weight (shown as the specifications); and drying to obtain the internally coated woven bag product.
Description
Technical field
The present invention relates to a kind of painting method, specifically, relate to apply in a kind of woven bag the polyether Glycols composition process.
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 face coat with polyvinyl resin.This coating is aging coming off easily, and also not wear-resisting, service life is shorter.The manufacture method of this kind face coat woven bag is: first weaving fiber tubular article on circular loom, then coated with resins is joined in the extruder, and 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 larger, and factory building is also had requirement; Simultaneously environment and operating personnel's health 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, provide a kind of wear-resisting, corrosion-resistant, intensity is high, long service life, 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 inner liner, and improvements are that described inner liner forms lining by spraying method in fiber braiding layer inside.
Described fiber braiding layer is take polypropylene (English name pp) as main raw material, through extruding, stretch the formation flat filament, weaves, works out through circular loom again.The thickness of described inner liner is 0.1～0.6mm.
Woven bag preparation method of the present invention is: warp and the parallel that will adopt fibrous material to make on circular loom first are woven into the tubular fiber braiding layer, then spray painting is formed liner in the braid inboard, described coating comprises following component (parts by mass) and content:
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 ultra-violet absorber 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 mixture that obtains is stretched by extruder and wire drawing machine; 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, corrosion-resistant, 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 industry raw material, agrochemical, the pulverulent materials such as building building cement.Woven bag painting method provided by the invention has improved prior art and has used extruder at woven bag outer surface 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.
Embodiment 1
Be that to add weight portion be 0.4 part antioxidant 1010, the ultra-violet absorber 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 mixture that obtains is stretched rolling and make polyacrylic fibres by extruder and wire drawing machine.Be woven into tubular fiber braiding layer with polyacrylic fibres as warp and parallel at circular loom, then spray painting formed liner in the braid inboard, described coating comprises following component (parts by mass) and content:
After scene preparation fully mixes, at temperature 45 C, under the condition of pressure 10MPa, utilize spray gun spraying in the inboard of fiber braiding layer the above-mentioned coating component, form lining coating, coating thickness 0.1mm namely obtains the woven bag of interior spraying after the heated-air drying.
Embodiment 2
Repeat embodiment 1, the coating processes of woven bag and embodiment 1 are roughly the same, and difference is that coating comprises following component (parts by mass) and content:
60 ℃ of spraying temperatures, spray pressure 15MPa, coating thickness 0.6mm.
Embodiment 3
Repeat embodiment 1, the coating processes of woven bag and embodiment 1 are roughly the same, and difference is that coating comprises following component (parts by mass) and content:
53 ℃ of spraying temperatures, spray pressure 13MPa, coating thickness 0.3mm.
