Problems solved by technology

[0002] The nano-anti-ultraviolet finishing agent uses a light-resistant stabilizer as the base material, and the light stabilizer enters the fiber in the form of nanoparticles through the baking method and is fixed on the fiber, so that the fabric has excellent anti-ultraviolet performance; the traditional anti-ultraviolet finishing agent uses nano The material is directly synthesized, which reduces the anti-ultraviolet performance, does not have antibacterial properties, is not conducive to user use, and is troublesome to make, time-consuming and laborious, which is not conducive to user production. At the same time, the raw materials of traditional anti-ultraviolet finishing agents are expensive, which increases production costs and is not conducive to processing and production; For these defects, it is necessary to design a preparation method of chitosan-based anti-ultraviolet finishing agent

Abstract

The invention discloses a preparation method of a chitosan-based uvioresistant finishing agent. A formula of the chitosan-based uvioresistant finishing agent is prepared from the following componentsin percentage by mass: 15-25% of ammonium polyphosphate, 20-30% of chitosan, 15-25% of sodium lactate, 10-20% of 2,4-dihydroxy benzophenone, 2-4% of 4-nitro-1, 10-20% of titanium dioxide, 1-3% of sodium hydroxide, 5-10% of methylbenzene, 0.5-1% of citric acid, 0.5-1% of ethyl alcohol and 1-3% of a dispersing agent. According to the preparation method, safety and reliability are achieved, the chitosan-based uvioresistant finishing agent is commonly prepared by adopting the chitosan as a processing raw material and adding ammonium polyphosphate, sodium lactate, 2,4-dihydroxy benzophenone, 4-nitro-1, titanium dioxide, sodium hydroxide and methylbenzene, the ultraviolet resistance is enhanced, meanwhile, the antibacterial property is achieved, user use is facilitated, making is simple and convenient, time and labor are saved, and user production is facilitated.
