Problems solved by technology

However, there are few reports in this respect in China. The domestic research on the surface properties of UV-cured coatings still focuses on the wear resistance and scratch resistance of the coating film (Xu Guocai, Zhao Shilin. Coating Industry, 2003, 33 (8))

Abstract

The invention provides an effective UV-cured hydrophobic contamination-resistant coating and a preparation method thereof. The UV-cured hydrophobic contamination-resistant coating is obtained by adding modified nano-silicon dioxide to photosensitive resin, and dispersing and defoaming the modified nano-silicon dioxide. The modified nano-silicon dioxide accounts for 0.1%-20% of the mass of the photosensitive resin based on the mass of the silicon dioxide; the modified nano-silicon dioxide is made by the following method: nano-silicon dioxide particles are added to an organic solvent in which a surfactant is dissolved, evenly stirred, dried in vacuum and pulverized to obtain the modified nano-silicon dioxide. The coating has the main beneficial effects as follows: the preparation method is simple and easy to be operated, the obtained UV-cured hydrophobic contamination-resistant coating has good hydrophobic self-cleaning function and wide application prospect.

Description

(1) Technical field [0001] The invention relates to an ultraviolet light-cured hydrophobic and antifouling coating and a preparation method thereof. (2) Background technology [0002] Hydrophobic and stain-resistant materials refer to materials with hydrophobic and self-cleaning functions on the surface of the coating film. Due to its unique properties, it has broad application prospects in exterior wall and decorative coatings. [0003] Although there are also many reports and products about surface antifouling. But the main ones are solvent and latex coatings modified by silicone / fluorine (see: JP2007-290377377; JP2000-309749), and another example: Zhang Chaocan uses nano-SiO 2 The tarnish resistance of modified water-based exterior wall coatings (Zhang Chaocan; Tang Xianwen; He Dongming; Xie Minli; Shan Songgao Journal of Wuhan University of Technology, 2003, 10), Jia Zhengfeng introduced MPTMS, MPSAEA and methyl methacrylate copolymerization into the polymer containing...
