Abstract

The invention relates to preparation of high glass adhesion UV (ultraviolet) resin. The preparation method is as follows: propenyl-containing nanosilicon dioxide is prepared from nanosilicon dioxide modified by acrylic monomers, and then is blended with fluorine-containing acrylic resin to prepare an even nanosilicon dioxide inorganic-organic hybrid composite system by an advanced light curing technology, and the high glass adhesion UV (ultraviolet) resin is high in adhesion on glass surfaces. In a light polymerization process of the product, the nanosilicon dioxide modified by the acrylic monomers is polymerized with the fluorine-containing acrylic resin by chemical bonds, so that the nanosilicon dioxide is more evenly distributed in the polymer. Product curing analysis aims to improve the product adhesion and wear resistance and improve application of the nanosilicon dioxide composite acrylic monomers in the coating field.

Description

technical field [0001] The invention relates to acrylic monomer modified nano-silica particles, uniformly dispersed in fluorine-containing acrylic monomer and resin to prepare organic-inorganic hybrid UV resin formula, which has high adhesion on glass surface. Background technique [0002] Nano-silica has a three-dimensional network structure, has a large specific surface area, shows great activity, can form a network structure when the paint is dry, and at the same time increases the strength and smoothness of the paint, and improves the suspension of the pigment. It can keep the color of the paint for a long time without fading. In the interior and exterior wall coatings of buildings, if nano-silica is added, the can-opening effect of the coating can be significantly improved. The coating does not layer, has thixotropy, anti-sagging, and good application performance, especially the anti-staining performance is greatly improved, and has Excellent self-cleaning ability and ...
