Abstract

The invention relates to a method for preparing an environment-friendly silicone-modified acrylate adhesive. Raw materials of the preparation method comprise a basic monomer, a modified monomer and an auxiliary agent, wherein the basic monomer comprises a hard monomer, a soft monomer and a crosslinking monomer; the modified monomer comprises a silane monomer, a coupling agent and inorganic nano-powder; the crosslinking monomer is glycidyl acrylate or glycidyl methacrylate; and the grain diameter of the inorganic nano-powder is less than 80 nanometers. In the preparation method, the crosslinking monomer adopts the glycidyl acrylate or the glycidyl methacrylate so as to be environment-friendly. The product prepared by the method is a nanometer / silicone double-modified molecular composite polymer material. The molecular composite material is combined with the advantages of two polymer materials, namely silicone and polyacrylic ester and an inorganic nanometer material, and has better performance and broad application.
