Abstract

The invention relates to a high-strength casting reparation adhesive comprising the components of: 85 parts of an epoxy resin, 4 parts of acrylonitrile, 2 parts of dibutyl, 2 parts of dimethylaniline, 2 parts of epoxy vegetable oil, 2 parts of polyacrylamide, 8 parts of ammonium polyphosphate, and 4 parts of methacrylate. The casting reparation adhesive provided by the invention has the advantages of high bonding strength, short curing period, high-temperature resistance, pressure resistance, and long service life.

Description

technical field [0001] The invention relates to a chemical product, in particular to a high-strength casting repair adhesive. Background technique [0002] After the pores are generated in the casting, the effective bearing area will be reduced, and stress concentration will be caused around the pores, which will reduce the impact resistance and fatigue resistance of the casting. Pores will also reduce the compactness of castings, causing some castings that are required to withstand hydrostatic tests to be scrapped. Repairing these defects requires skilled workers to consume a lot of materials and time, and if they are not repaired, they will become waste products. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a high-strength casting repair adhesive. [0004] In order to solve the above-mentioned technical problems, the high-strength casting repair adhesive of the present invention comprises the following components, ...
