Problems solved by technology

The adhesive coating obtained by this invention is temperature-resistant and wear-resistant, but its disadvantages are also obvious. On the one hand, it also considers the particle size of the filler from the perspective of the densest space; on the other hand, it does not consider the adhesive coating. When the temperature shock is severe, its internal structure may undergo destructive changes, causing the adhesive coating to be damaged and peeled off from the inside, thus failing

Abstract

The invention discloses a high-temperature high-strength adhesive wear-resistant material and a preparation method thereof. The high-temperature high-strength adhesive wear-resistant material is composed of A and B components, and A component includes epoxy resin, nano filler fiber, toughening agent, hard filler, self-lubricating filler, metal carbide filler Material, aluminum powder, B component includes curing agent, thixotropic agent, silane coupling agent. The present invention covers the adhesive components of wear-resistant materials by using hard fillers with specific specifications to prevent the adhesive components from being directly eroded and peeled off by the erosion medium, and also adds nano filler fibers to ensure that the adhesive components can be Form a network structure to prevent the adhesive components from being eroded. At the same time, the formula also contains aluminum powder, which prevents static electricity accumulation while being anti-corrosion. The curing agent is dicyandiamide or 2‑ethyl‑4‑methylimidazole The material also has good adhesion and wear resistance at -60°C-250°C.

Description

technical field [0001] The invention belongs to the technical field of adhesive wear-resistant materials, and in particular relates to a high-temperature, high-strength adhesive wear-resistant material and a preparation method thereof. Background technique [0002] With the development of economy and society, people are more and more aware of the importance of reducing the wear of machinery and equipment, and the wear-resistant adhesive coating has been widely used and developed at home and abroad. Wear-resistant adhesive coating refers to a surface that mixes thermosetting polymer adhesive matrix and hard wear-resistant particles (reinforcing phase) according to a certain process and ratio, and coats it on the cleaned workpiece surface to obtain the required wear resistance. technology. This kind of wear-resistant coating has simple coating process, low cost, and small curing shrinkage. It can be used not only for corrosion-resistant and wear-resistant preset coatings on t...
