Abstract

The invention discloses waterborne high-moisture-permeability anti-ultraviolet functional coating glue which is prepared in the mode that 90-110 parts of ethylene glycol polyether with the average molecular weight being 2000, 90-110 parts of ethylene glycol polyether with the average molecular weight being 1000, 55-60 parts of toluene diisocynate, 60-65 parts of acetone, 8-10 parts of 1,4-butanediol and 2.5-4 parts of nano titanium dioxide are polymerized, and the materials are dispersed in 580-620 parts of deionized water and thickened through 1.5-2 parts of associative polyurethane flatting and rheological agents. The moisture-permeable anti-ultraviolet functional coating glue is particularly suitable for 15-20D fine-denier nylon chemical fabric, and is soft in using hand feel and good in fastness.

Description

technical field [0001] The invention relates to a coating glue for after-finishing of textiles. The glue coating is used to process 15-20D fine-denier nylon chemical fiber cloth, which has two functions of high moisture permeability and anti-ultraviolet rays. Its technical feature is to use nano-titanium dioxide to modify the water-based polyurethane prepolymer to synthesize a water-based coating adhesive with high moisture permeability and anti-ultraviolet function. Background technique [0002] Summer sun protection skin clothing is mostly made of 15-20D fine-denier nylon chemical fiber cloth. After coating processing, it is required to have a moisture permeability of more than 3500 (according to GB / T12704.1-2009 standard), and an anti-ultraviolet UVA index value of 5%. Below, the anti-ultraviolet UVB index value is below 5%, and the anti-ultraviolet UPF index value is above 50 (the anti-ultraviolet index is tested according to: GB / T18830:2009 standard). This coated fabri...
