The invention discloses a high-strength adhesive for a solid surface material. The adhesive comprises an A agent and a B agent, wherein the A agent comprises the following components, in parts by weight: 100 parts of methyl methacrylate, 1-20 parts of a methacrylic acid functional monomer, 0.1-0.5 part of n-dodecanethiol, 0.1-0.3 parts of azobisisobutyronitrile, 0.5-5 parts of a thickening agent and 0.2-5 parts of an accelerant; and the B agent comprises the following components, in parts by weight: 8-9.5 parts of dioctyl terephthalate and 0.1-5 parts of benzoyl peroxide. According to the adhesive provided by the invention, the methacrylic acid functional monomer is introduced into the adhesive for the solid surface material, the functional monomer has the characteristics of improving bending resistance, adhesion performance and impact resistance in the adhesive, so that the bonding strength is greatly improved, and requirements of higher construction standards are met. 本发明公开了一种高强度实体面材胶粘剂，包括A剂和B剂，其中，所述A剂包括如下重
