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 asurfactant 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 curing hydrophobic antifouling paint and a preparation method thereof. (2) Background technology [0002] The hydrophobic antifouling material refers to the material with the function of hydrophobic self-cleaning on the surface of the coating film. Due to its unique properties, it has broad application prospects in exterior walls and decorative coatings. [0003] At present, although there are many reports and products about surface anti-fouling. But the main ones are solvent-based and latex coatings modified with silicone / fluorine (see: JP2007-290 377377; JP2000-309749), another example: Zhang Chaocan uses nano-SiO 2 Stain 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). Fluorine monomer, etc., to obtain a coating with hydrophobicity (Jia Zhengfeng, Zhou Jingfang, Dang Ho...
