Abstract

The invention relates to a manufacture process of a PE braided base cloth digital printing material. The manufacture process includes a PE braided base cloth layer. Firstly a lower layer of macromolecule material base coating is arranged on the surface of the PE braided base cloth layer, then an upper layer of macromolecule material top coating is arranged again on the surface of the lower layer of the macromolecule material base coating. The manufacture process includes: putting the PE braided base cloth layer and coating in, scraping, drying in sections, pressing and adhering, cooling in sections, putting the coating in, scraping, drying in sections, pressing and adhering, cooling in sections, rolling, testing the quality, slitting and packaging, and storing. The materials have good adhesive force by coating a mixture of polyurethane resin, silicon dioxide, defoamer, dispersing agent, and solvent twice on the PE braided base cloth. The printed patterns have clear outlines. The product has high strength, high weathering resistance, and high wear resistance. The material is green and environment-friendly.

2) primary coat: PE braiding base cloth layer passes through scraper gap with the speed of 5-20m/min, by the polyurethane resin mixture that contains 50%-70%, the dimethylbenzene of 20%-40%, the defoamer of 0.1%-0.3%, the macromolecule mixture of the formulation material of the dispersant of 0.3%-0.5% is at the uniform velocity coated on PE braiding base cloth layer;

3) the PE braiding base cloth layer that has applied macromolecule mixture need be dried through five sections of intensification temperature controls; First paragraph oven temperature is controlled at 50-70 ℃, and second segment oven temperature is controlled at 60-80 ℃, and the 3rd section of oven temperature is controlled at 70-90 ℃, and the 4th section of oven temperature is controlled at 60-80 ℃, and the 5th section of oven temperature is controlled at 55-75 ℃;

4) pressurizing attaching, makes priming coat and PE braiding base cloth layer in conjunction with tightr;

5) divide four chill rolls cooling the PE braiding base cloth layer of oven dry, what in four chill rolls, inject is recirculated water cooling under normal temperature, and the PE braiding base cloth layer of oven dry carries out cooling through four chill rolls successively;

6) face is coated with: PE braiding base cloth layer passes through scraper gap with the speed of 5-20m/min, by the polyurethane resin mixture that contains 50%-70%, the dimethylbenzene of 20%-40%, the silica of 3%-6%, the defoamer of 0.1%-0.3%, the macromolecule mixture of the formula of the dispersant of 0.3%-0.5% is at the uniform velocity coated on priming coat, forms finishing coat;

7) repeat above-mentioned 3), 4), 5) step once;

8) rolling;

9) quality inspection, cuts packing, warehouse-in.

The polyurethane resin mixture that described lower floor macromolecular material priming coat is 50%-70%, the dimethylbenzene of 20%-40%, the defoamer of 0.1%-0.3%, the dispersant of 0.3%-0.5%, the polyurethane resin mixture that described upper strata macromolecular material finishing coat is 50%-70%, the dimethylbenzene of 20%-40%, the silica of 3%-6%, the defoamer of 0.1%-0.3%, the dispersant of 0.3%-0.5%.

Obvious advantage and the effect implemented after this technology are: by twice coating polyurethane resin on PE braiding base cloth layer, silica, defoamer, dispersant, the mixture of solvent, makes material adhesive force good, picture and text clear-cut, product strength is high, and weatherability, mar proof are strong, and give material environmental protection performance.
