Problems solved by technology

[0004] The curtains in the above invention patents all have a certain anti-ultraviolet function, which can isolate the ultraviolet rays in the sun and avoid ultraviolet rays from harming people's skin, but the zinc oxide and titanium dioxide in the anti-ultraviolet composite layer of CN 102362775 A cannot be effectively combined with the curtain fabric matrix , so the ability to absorb ultraviolet rays is not good, and the anti-ultraviolet layer coating in CN 102805545 A is an acrylic coating, and the anti-ultraviolet ability is effective

Abstract

The invention relates to composite ultraviolet-proof finishing liquid. The composite ultraviolet-proof finishing liquid comprises 25-30 g / L of nanometer oxide, 15-30 g / L of metallo chelate, 20-30 g / L of synergist, 15-20 g / L of ethyl alcohol, 10-15 g / L of methyl alcohol, 10-15 g / L of urea, 2-4 g / L of glycerinum, 0.5-1 g / L of polyoxyethylene ether, 0.5-1 g / L of azodiisobutyronitrile, 0.3-1 g / L of flatting agent, 0.2-1 g / L of antifoaming agent, and 1-2 g / L of curing agent, water serves as the solvent, the nanometer oxide is the powder mixture of ZnO, TiO2 and SiO2. Woven cloth treated through the finishing liquid has the excellent ultraviolet-proof function, the shading coefficient reaches to over 70%, the ultraviolet light shielding rate reaches to over 98%, and the ultraviolet protection factor (UPF) is higher than 40.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a composite anti-ultraviolet finishing liquid and its preparation method and application. Background technique [0002] Curtains are an important part of the soft decoration of the living room, and play an important role in the beautification of the modern home environment and the construction of the environment. Curtains are especially important in high-speed rail. Because the high-speed rail runs faster, the light outside the car will flash to the human eye with the high-speed running of the car. Close your eyes and rest your mind, the poor quality of the curtains will affect the rest of the passengers. [0003] In recent years, with the development of science and technology, various new functional curtain woven fabrics have emerged, such as curtain woven fabrics with anti-ultraviolet function, which can absorb ultraviolet rays to a certain extent, so as to avoid the harmful eff...
