Embodiment 1

[0023] a) pretreatment on the surface of the inorganic or organic substrate, b) applying a mixed solution of the photoinitiator benzoin and the polymerizable monomer 1,6-hexanediol diacrylate to the inorganic or organic substrate, After 15 minutes of low-light irradiation and ventilation for a period of time, a 50um undried viscous layer is formed on the surface, c) spray 10nm TiO2 dispersion solution on such a viscous layer, d) pass UV / VIS radiation or electrons The beam cures and dries the coating.

Embodiment 2

[0025] The same method as Example 1, except that the viscous layer is 10um.

Embodiment 3

[0027] The same method as Example 1, except that the viscous layer is 100um.

Abstract

The invention provides a method for preparation of an air purification strong-adhesion coating layer on the surface of an inorganic or organic substrate. The method can effectively strongly fix nano TiO2 on the surface of a building material or a decoration material, a polymer film is formed on the surface, the concentration is obstructed and indoor harmful gas is decomposed, so as to achieve thepurpose of air purification. The invention provides the method for preparation of the air purification surface coating layer, wherein the method includes the steps: a) preprocessing on the surface ofthe inorganic or organic substrate; b) applying a mixed solution of a photoinitiator and a polymerizable monomer onto the inorganic or organic substrate, irradiating with micro light and ventilating for a period of time, and forming a 10-100 [mu]m viscous layer on the surface; c) spraying the viscous layer with a TiO2 dispersive solution; and d) solidifying and drying the coating layer through UV / VIS radiation or electron beams.

Description

technical field [0001] The invention belongs to the field of surface coatings, in particular to a polymeric layer capable of purifying air and strongly adhering to the surface. Background technique [0002] Indoor air pollution has become one of the main factors threatening human health. [0003] Photocurable materials are mainly composed of photocurable resins, reactive diluents and photoinitiators. Photoinitiator refers to a class of compounds that can be excited into free radicals or cations under the action of light. The photophysical and photochemical properties of photoinitiators are very important for the control of photoinitiation and photopolymerization process. [0004] my country is a country with a high incidence of cancer. A cancer patient appears in almost five minutes. According to a large number of research reports, the toxic and harmful gases produced by interior decoration, furniture, and electrical appliances are the main cause of most cancers. Modern peo...
