Abstract

The invention discloses an environmental-friendly internal coating process for a plastic woven bag, which particularly comprises the following steps: weaving finished product flat yarns into woven bagcloth by a weaving machine and using the woven bag cloth as coating base cloth for later use; and preparing an environmental-friendly paint for coating for later use, wherein a formula of the environmental-friendly paint consists of raw materials in parts by mass as follows: 6o to 80 parts of polypropylene, 40 to 60 parts of linear polyethylene, 5 to 10 parts of an initiator, 6 to 8 parts of a rare earth stabilizer, 7 to 12 parts of an antioxidant, 8 to 15 parts of a corrosion inhibitor, 6 to 11 parts of a flame retardant and 4 to 9 parts of an ultraviolet light absorber. According to the invention, the environmental-friendly raw materials are adopted to form the paint formula, so that the produced woven bag has excellent liquidity, corrosion resistance, high-temperature resistance and good machining performance and environmental-friendly performance and meanwhile has functions of preventing fire, absorbing ultraviolet rays and resisting to oxidation; moreover, the internal coating process takes spray coating as the main, so that demands for production equipment can be reduced, the production efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a coating process, in particular to an environmentally friendly inner coating process for plastic woven bags. Background technique [0002] Woven bags are usually woven from cross-woven wires with slight seams at the intersections of the woven wires. Therefore, polyethylene resin is usually used for the surface coating of woven bags. The manufacturing method of this kind of woven bag is to weave the fiber tube on the circular loom first, then add the coating resin to the extruder, and pass through the extruder. Extruded hot melt film, coated on the outer surface of the braided cylinder to become a product. This process requires more production equipment, consumes a lot of energy, and the coating is easy to age and fall off, the wear resistance is not strong, and the service life is short. Contents of the invention [0003] The object of the present invention is to provide an environmentally friendly inner coating process fo...
