Abstract

The invention relates to a high impact-resistant epoxy resin filling adhesive and a preparation method thereof. The high impact-resistant epoxy resin filling adhesive consists of a component A and a curing agent in a weight ratio of 100:6.5-100:7.5, wherein the component A consists of the following raw materials in percentage by weight: 20 to 60 percent of epoxy resin, 5 to 15 percent of toughening agent, 0.1 to 0.5 percent of thixotropic agent, 2 to 10 percent of diluent, 30 to 70 percent of filler and 0.1 to 0.5 percent of aid; and the curing agent is one or a mixture of more of straight chain aliphatic amine, aliphatic cyclic amine, polyether amine and low molecular weight polyamide. The preparation method for the high impact-resistant epoxy resin filling adhesive comprises the following steps of: mixing the component A and the curing agent in a proper weight ratio, and curing at the temperature of between 10 and 35DEG C for 16 hours.

Description

technical field [0001] The invention relates to a high-impact epoxy resin filler and a preparation method thereof, belonging to the technical field of epoxy resin adhesives. Background technique [0002] Epoxy resin filler is an important industrial material, which is widely used in shipbuilding, electric power, petroleum, mining and non-ferrous metallurgy industries, as pad filling or back plate filling, etc. Taking marine applications as an example, at present, the proportion of China's shipbuilding industry in the global market is rising significantly, and China has become one of the world's important shipbuilding centers. The trend of international industrial transfer has shown the huge opportunities of the shipbuilding industry in front of Chinese enterprises, providing a broad space for the development of epoxy resin fillers for ships. [0003] Before the advent of marine epoxy resin fillers, in order to ensure the consistency of the shafting line, the main and auxili...
