Light-cured acrylic acid adhesive and preparation method thereof

The invention provides a photocuring acrylic acid adhesive and a preparation method thereof, and the photocuring acrylic acid adhesive is prepared from the following raw materials in parts by weight: 33.45-60 parts of modified epoxy acrylic resin; 0-25 parts of polyester acrylic acid; 24.3 to 40 parts of a reactive diluent; 0.8 to 2 parts of a silane coupling agent; 3-4 parts of a photoinitiator; 1-15 parts of polymer composite talcum powder; 0.7 to 1.55 parts of an auxiliary agent; the high-molecular composite talcum powder is prepared from unmodified talcum powder, a copolymer a and a copolymer b, wherein the unmodified talcum powder is uniformly dispersed in matrixes of the copolymer a and the copolymer; the structural formula of the copolymer a is # imgabs0 #, wherein n is equal to 200 to 2000; and the structural formula of the copolymer b is # imgabs 1 #, wherein m is equal to 28-69. The preparation method of the light-cured acrylic acid adhesive is simple and easy to operate, the light-cured acrylic aci
