Abstract

The invention relates to the field of UV coatings, and particularly discloses a UV antibacterial and mildew-proof finish paint and a preparation method thereof. The UV antibacterial and mildew-proof finish paint is prepared from aromatic polyurethane acrylic resin, UV hyperbranched resin, a reactive diluent, a photoinitiator, aluminum oxide, fumed silica, a bactericide and other auxiliary agents in certain parts by mass, the preparation method comprises the following steps: mixing the aromatic polyurethane acrylic resin, the UV hyperbranched resin and part of the components of the reactive diluent, then adding the photoinitiator and part of the components of other auxiliary agents, performing mixing, adding the fumed silica and the other components in the other auxiliary agents and the other components in the reactive diluent, and performing mixing, and finally, adding the rest components of the reactive diluent, the rest components of the other auxiliary agents and the bactericide, and uniformly mixing the substances to obtain the UV antibacterial and mildew-proof finish paint. The UV antibacterial and mildew-proof finish paint can be used for coating the surfaces of various indoor and outdoor objects, and has the advantage of excellent yellowing resistance.

Description

technical field [0001] The application relates to the field of UV coatings, more specifically, it relates to a UV antibacterial and antifungal topcoat and a preparation method thereof. Background technique [0002] UV coatings refer to coatings that are cured by UV radiation, and their solid content can be as high as 100%, so they have no volatile components and do not pollute the environment. With the improvement of people's awareness of consumption, higher requirements are put forward for their own health. Nowadays, health and environmental protection have become the first requirement that people pay most attention to when decorating. There are also more requirements for environmental protection products. Antibacterial ceramics, antibacterial wallpapers and other anti-mold and anti-bacterial products are becoming the new favorites in the home building materials market. [0003] In the related art, the UV antibacterial coating uses aromatic urethane acrylate as a matrix re...
