Abstract

The invention relates to a preparation method of a photo-cured titanate air purification finishing agent specially used for fiber fabric. The preparation method comprises the steps of mixing deionized water, biomass surface active agent, cage-shaped polyhedron oligomeric silsesquioxane, monoclinic crystal type nano Bi4Ti3O12 particles and silver nitrate according to the mass ratio of 1: (0.01-0.05): (0.05-0.15): (0.02-0.1): (0.001-0.003), stirring and then adding ammonia water for reaction to obtain functional reaction liquid; heating the functional reaction liquid, dropwise adding urethane acrylate monomer into the functional reaction liquid for pre-emulsification, and cooling; adding sodium azide and propylene glycol block polyether, heating up to 60 DEG C, carrying out reaction for 2-4h, and adjusting the pH value to 7-8 to obtain the photo-cured titanate air purification finishing agent. The photo-cured titanate air purification finishing agent has good dispersion stability and has good air purification effect when being applied to a textile; furthermore, the preparation method is simple and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of preparation of air-purifying finishing agents, and in particular relates to a preparation method of a light-cured titanate air-purifying finishing agent special for fiber fabrics. Background technique [0002] According to the report of the World Health Organization, indoor air pollution causes 1.6 million deaths every year in the world, and an average of 1 person dies every 20 seconds. The annual excess deaths caused by indoor air pollution in China have reached 111,000, the excess number of emergency visits has reached 4.3 million, and the direct and indirect economic losses have reached 10.7 billion US dollars. [0003] In recent years, photocatalytic technology and indoor air purification technology have continued to cross-penetrate. Photocatalytic indoor air treatment technology has unique advantages such as good purification effect, simple operation, and no toxic and harmful intermediate products during the t...
