Abstract

The invention provides a thermosetting high-strength acrylate adhesive. The thermosetting high-strength acrylate adhesive is prepared from resin components and a curing agent component. The resin components include, by weight, 12-20 parts of epoxy modified acrylate resin, 20-45 parts of methyl methacrylate, 15-25 parts of chlorosulfonated polyethylene, 6-12 parts of methacrylic acid, 1-6 parts of aluminum acetylacetonate, 1-3 parts of allyl methacrylate, 0.3-0.8 part of hydrogen peroxide and 0.1-0.5 part of tris-(2,4-di-tert-butyl-pheny)phosphite ester. The curing agent component is 100 parts of butylaldehyde-aniline condensate. The prepared acrylate adhesive has good strength and impact resistance and also has structure adhesiveness, corrosion resistance and aging resistance.

Description

technical field [0001] The invention relates to a thermosetting high-strength acrylate adhesive, which belongs to the field of adhesives. Background technique [0002] With the rapid development of automobile lightweight and electrical and electronic products, adhesives have been widely used in the industrial field and people's daily life. Acrylic adhesive has the following characteristics: 1. Good weather resistance 2. Can realize oil surface bonding 3. High strength and shear resistance 4. Impact resistance and easy to use. However, common acrylic structural adhesives in practical applications cannot meet the requirements of use, and have defects such as poor strength, corrosion resistance and impact resistance. Therefore, to develop a better acrylate adhesive to meet the above defects. Contents of the invention [0003] Aiming at the product problems in the current market, the main technical problem to be solved by the present invention is to provide a thermosetting, ...
