Abstract

The invention discloses an ultraviolet cross-linked organosilicone modified acrylate copolymer emulsion which belongs to the field of high-molecular compounds. The ultraviolet cross-linked organosilicone modified acrylate copolymer emulsion is formed by constitutional repeating units and is a modified acrylate copolymer with a side chain containing an ultraviolet active group and an alkoxy siloxane group. The ultraviolet cross-linked organosilicone modified acrylate copolymer emulsion is obtained through the copolymerization reaction of an ultraviolet active single-functionality degree monomer, an alkoxy siloxane single-functionality degree monomer and a third single-functionality degree monomer. According to the ultraviolet cross-linked organosilicone modified acrylate copolymer emulsion, the side chain of the copolymer contains the ultraviolet active group and the alkoxy siloxane group, double crosslinking is realized, i.e. ultraviolet self-crosslinking and organosilicone self-crosslinking, and a high elastic material with good flexibility is formed, has high surface smoothness, strong contamination resistance, excellent adhesion resistance and no residual small molecules.

Description

technical field [0001] The present invention relates to a silicone-modified acrylate copolymer emulsion crosslinked by ultraviolet light, in particular to a silicone-modified acrylate copolymer emulsion obtained by participating in emulsion polymerization of ultraviolet light-active monomers, which belongs to polymer compounds field. Background technique [0002] Acrylate emulsion uses water as the reaction and dispersion medium, which is environmentally friendly and pollution-free. It is the main component of acrylic emulsion paint. Acrylate emulsion has many outstanding advantages, such as excellent light resistance, weather resistance, acid and alkali resistance, corrosion resistance and good oil resistance, and because of its low cost, acrylate emulsion is widely used in automobiles, construction and electromechanical products and other fields. However, conventional thermoplastic acrylate emulsions have disadvantages such as cold brittleness, hot stickiness, and low st...
