Embodiment 1

[0013] According to the polypropylene resin that is 100 parts by weight, add the antioxidant 1010 that is 0.4 part by weight, the ultraviolet absorber UV-327 that is 0.5 part by weight, the auxiliary antioxidant DLTP that is 0.6 part by weight; The mixture obtained is passed The extruder and wire drawing machine are stretched and wound to make polypropylene filament. On the circular loom, use polypropylene silk as warp and weft to weave into tubular fiber braided layer, then paint is sprayed on the inner side of braided layer to form inner liner, and described paint includes following components (mass parts) and content:

[0014]

[0015] After the above-mentioned coating components are fully mixed on-site, under the conditions of temperature 45°C and pressure 10MPa, use a spray gun to spray on the inner side of the fiber braided layer to form a lining coating with a spray thickness of 0.1mm. After hot air drying, the inner lining is obtained. Spray woven bags.

Embodiment 2

[0017] Repeat embodiment 1, the coating process of woven bag is roughly the same as embodiment 1, and difference is that coating comprises following component (mass part) and content:

[0018]

[0019] The spraying temperature is 60°C, the spraying pressure is 15MPa, and the spraying thickness is 0.6mm.

Embodiment 3

[0021] Repeat embodiment 1, the coating process of woven bag is roughly the same as embodiment 1, and difference is that coating comprises following component (mass part) and content:

[0022]

[0023] The spraying temperature is 53°C, the spraying pressure is 13MPa, and the spraying thickness is 0.3mm.

Abstract

The invention relates to an internal coating method for woven bags. The method comprises the following steps: weaving warp and weft made of fiber materials into a tubular fiber woven layer on a circular weaving machine, then coating paint prepared on site onto the inner side of the woven layer to form a lining, and finally drying to obtain the inner-coating woven bag product. The pain comprises the following ingredients in part by weight (shown as the specifications).

Description

technical field [0001] The invention relates to a coating method, in particular to a coating method for the inside of a woven bag. Background technique [0002] Woven bags are widely used in industry, agriculture, construction and other industries to transport powder products. Woven bags are usually woven from cross-woven wires, and there are tiny gaps at the intersections of the woven wires. In order to make up for this defect, people have used polyethylene resin for the surface coating of woven bags. This coating is easy to age and fall off, is not wear-resistant, and has a short service life. The manufacturing method of this kind of surface coated woven bag is: weave the fiber tube on the circular loom first, then add the coating resin into the extruder, extrude the hot melt film through the extruder, and coat it on the braided tube The outer surface of the object becomes a product. This production method requires more production equipment, consumes a lot of energy, a...
