Abstract

The invention is a breathable ultraviolet-resistant anti-static polyurethane resin coating adhesive and a preparation method thereof. The breathable ultraviolet-resistant anti-static polyurethane resin coating adhesive is prepared by compounding water-based breathable anti-static polyurethane resin, a blocked polyurethane crosslinking agent, nano zinc oxide and a thickening agent, wherein the water-based breathable anti-static polyurethane resin is prepared from components A, the blocked polyurethane crosslinking agent is prepared from components B, the components A comprise 50-200 parts of polyoxyethylene ether glycol, 50-200 parts of polyoxypropylene ether glycol, 1-5 parts of trimethylolpropane, 40-200 parts of polyisocyanate, 3-10 parts of a chain extender, 0.02-0.06 part of a catalyst, 30-60 parts of a solvent, 3-10 parts of sodium hydrogen carbonate, 3-10 parts of sodium hydrogen sulfite and 500-1,500 parts of deionized water, and the components B comprise 100-200 parts of 1.6-hexylidene diisocyanate trimer, 42-92 parts of acetone oxime or methyl ethyl methyl ethyl ketoxime, 0.02-0.06 part of a catalyst, 400-900 parts of a solvent and 30-80 parts of an ultraviolet-resistant additive. The breathable ultraviolet-resistant anti-static polyurethane resin coating adhesive has excellent air permeability, ultraviolet resistance and static resistance and has good dry and wet rubbing fastness.

Description

technical field [0001] The invention relates to a breathable, anti-ultraviolet and antistatic polyurethane resin coating adhesive for textile fabrics and a preparation method. [0002] It contains two components: one is air-permeable, antistatic water-based polyurethane resin; the other is an anti-ultraviolet polyurethane cross-linking agent, which is prepared by mixing the two components. Background technique [0003] At present, there are many kinds of functional coating adhesives for textile fabrics. [0004] CN 101481580A discloses a waterproof, low-temperature-resistant soft, moisture-permeable coating glue and its preparation method. The patent uses lignocellulose powder, silicone polyurethane resin, polyisocyanate or melamine resin as a cross-linking agent. Waterproof, low temperature resistant soft, moisture-permeable coating glue. The patent provides a waterproof, low-temperature, and moisture-permeable coating adhesive. The coating adhesive does not have an anti...
