Abstract

The invention discloses a quick-positioning two-component acrylate structural adhesive and a preparation method and a use method thereof. The adhesive comprises a component A and a component B, an acrylate structural adhesive and an epoxy structural adhesive are organically combined together by adopting a blending mode, and thiol curing agents, epoxy resin and epoxy latent curing agents are addedinto different components, so that the thiol curing agents, the epoxy resin and the epoxy latent curing agents are mutually promoted to react. When the component A and the component B are used after being mixed according to the volume ratio of 10:1, the storage is stable at normal temperature, and the operation time is longer; the thiol curing agent of the component A and the epoxy resin of the component B can be initiated to react by low-temperature heating to achieve the quick-positioning effect, and the generated heat is used for initiate the acrylic acid system reaction to form an interpenetration network structure, and the acrylate structural adhesive and the epoxy structural adhesive are organically combined, the adjustable range of raw materials is large, and the structural adhesivewith excellent comprehensive performance is obtained through blending modification.

Description

technical field [0001] The invention belongs to the field of acrylic structural adhesives, in particular to a fast-positioning two-component acrylic structural adhesive. Background technique [0002] The second-generation acrylic structural adhesive can be cured at room temperature, the operation process is simple, and the bonding range is wide. It is suitable for bonding most metal and non-metal materials. The surface treatment requirements are not strict, and even oil surface bonding is possible. 100% solid content, low curing shrinkage, high peel strength, impact resistance and good weather resistance strength, structural bonding halogen-free metal structural adhesive. Because of its solvent-free and halogen-free structural adhesive, it is widely used in the bonding and fixing of electronic assembly, handheld products, communication equipment, automobile manufacturing, rail transit, elevators, ships, mobile phone / notebook casings and tablet computers. In recent years, wi...
