Abstract

The invention discloses a high temperature-resistant two-component acrylicester adhesive and a preparation method thereof. The adhesive comprises the copolymer of heat resistant acrylate monomer and high temperature-resistant modified resin, wherein the glass-transition temperature of the heat resistant acrylate monomer is more than 50 DEG C, the heat resistant acrylate monomer, at least containing an ethane, comprises one or more of single-methacrylate monomer, dimethacrylate monomer, tri-methacrylate monomer and poly-methacrylate monomer; and the high temperature-resistant modified resin is one or more of maleimide with I-IV structures, triallyl cyanurate (TAC) with a V structure, triallyl isocyanurate (TAIC) with a VI structure, 1,2,4-benzenetricarboxylic acid triallyl ester (TAT) with a VII structure, and 1,3,5-benzenetricarboxylic acid triallyl ester with a VIII structure.

Description

technical field [0001] The invention relates to a two-component acrylic adhesive and a preparation method thereof, in particular to a two-component acrylic adhesive with good high temperature resistance and a preparation method thereof. Background technique [0002] The two-component acrylate adhesive contains two components, A and B, wherein component A contains acrylate monomer copolymer and initiator, and component B contains acrylate monomer copolymer accelerator. When in use, when the two components A and B are mixed, the initiator and the accelerator interact to initiate free radical polymerization of monomers containing unsaturated bonds at room temperature, thereby curing the glue. Two-component acrylic adhesives are used in a wide range of fields, including structural bonding, rapid assembly and assembly, emergency repair, anti-seepage and plugging in industrial and engineering operations. They have fast curing speed, high strength, good toughness and adaptability. ...
