Formula for epoxy resin adhesive

Abstract

The invention discloses a formula for epoxy resin adhesive. The formula comprises the following ingredients in parts by weight: 20-30 parts of bisphenol A epoxy resin, 5-15 parts of chopped carbon fiber, 2-5 parts of curing agent, 0.5-2 parts of flexibilizer, 1-2 parts of accelerant, 1-2 parts of coupling reagent, 2-5 parts of silicon dioxide powder, 5-15 parts of distilled water, 2-3 parts of 2-mercaptobenzimidazole and 1-2 parts of thickening agent. The epoxy resin adhesive has the characteristics of good viscidity, high heat conductivity, good chemical stability, and small possibility of deterioration, and therefore, heat resistance and reliability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a formulation of an epoxy resin adhesive. Background technique [0002] Carbon fiber reinforcement and repair of concrete structures is a new type of reinforcement and reinforcement technology that emerged in developed countries such as Japan and the United States in the late 1980s and early 1990s. It has been widely used in the reinforcement and repair of bridges and building concrete structures. . Compared with the traditional reinforcement technology, carbon fiber reinforcement has the advantages of high strength and high efficiency, excellent corrosion resistance, durability and good fatigue resistance, does not increase the weight and volume of components, and has a wide range of applications. [0003] Since the carbon fiber itself has very good mechanical properties, the adhesive often becomes a key factor in determining the quality of the carbon fiber reinforcement proce...
