Abstract

The invention discloses a multi-response polymer adhesive material. The material is prepared by using the following method: carrying out a reaction at 75-85 DEG C and normal pressure for 12h in the existence of nitrogen by taking a dopamine monomer, a thermosensitive monomer N,N-dimethylacrylamide and an alkyl acrylate monomer as raw materials, azobisisobutyronitrile as an initiator and an anhydrous organic solvent as a reaction medium, and carrying out conventional separation to obtain a multi-response underwater polymer adhesive, wherein the molar ratio of the dopamine monomer to the alkyl acrylate monomer to the thermosensitive acrylic acid monomer is 1 / 25 / 75-1 / 75 / 25, and the molar ratio of azobisisobutyronitrile to the dopamine monomer is 2 / 25-31. The underwater polymer adhesive material with multi-response property is prepared by the copolymerization of several functional monomers; and different from the adhesion property of a traditional underwater adhesive material, the multi-response polymer adhesive material realizes the dynamic regulation of adhesion strength and the effective separation of adhered materials.

Description

technical field

[0001] The invention relates to a multi-response polymer adhesive adhesive material and its application, belonging to the technical field of engineering. Background technique

[0002] Underwater adhesive material is a common engineering material, which is mainly used for the mutual bonding between materials and the sealing of moving parts in underwater operations. Compared with the traditional mechanical reinforcement and gasket sealing technology, the underwater adhesive material prepared by chemical synthesis has reliable, stable and durable adhesive performance.

[0003] Most underwater adhesives on the market are usually based on epoxy resin systems. Its preparation method is usually to stir and disperse the auxiliary agent with the epoxy resin component A and the curing agent B component separately, and then uniformly mix the auxiliary agent-containing component A and component B. Although this type of glue has excellent adhesive performance under wate...
