Abstract

A nano photocatalytic fluorocarbon resin paint is composed of modified synthetic resin and solidifying agent. Said modified synthetic resin is prepared through adding nano slurry to the solution of synthetic resin, mixing with solvent and pigment, grinding, and filtering. Its advantages are high stability and photocatalyzing efficiency of its coated layer, and excellent weatherability.

Description

technical field [0001] The invention relates to paint technology, in particular to a fluorocarbon resin paint with photocatalytic function and a preparation method thereof. Background technique [0002] With the rapid development of industry, it has brought serious pollution to the environment, such as organophosphorus pesticides, aromatic amino compounds, chlorine solvents, benzene solvents, etc. to water pollution, nitrogen oxides (NO x ) and sulfur oxides (SO x ) to air pollution. These harmful substances are very harmful to the human body, and these low-concentration harmful substances are not easy to eliminate and are relatively stable. Since the discovery of irradiated TiO by Fujishima 2 Since the continuous oxidation and reduction reactions of water can occur on the surface, people have studied the photocatalytic reaction of N-type semiconductor materials. It has been confirmed that TiO 2 , ZnO, CdS, SnO 2 、WO 3 , Fe 2 o 3 etc., all have photocatalytic functi...
