Wear-resistant resin adhesive

Abstract

The invention discloses a wear-resistant resin adhesive, which comprises the following components, by mass, 50-80 parts of an epoxy resin pouring sealant, 100-120 parts of a bisphenol A epoxy resin, 120-150 parts of a phenolic resin, 100-150 parts of a non-saturated resin, 150-200 parts of an ABS resin, 100-150 parts of a polyester resin, 120-180 parts of a polyamide resin, 100-120 parts of a rosin resin, 20-30 parts of polytetrafluoroethylene micro powder, 30-35 parts of a polysiloxane compound wear-resistant agent, 15-20 parts of a calcium oxide lubricant, 10-15 parts of a dispersant, and 10-15 parts of a brightener. The cured wear-resistant resin adhesive has no bubble, is flat in surface, good in glossiness, high in hardness, and excellent in leakproofness, has good properties of high temperature resistance, acid and alkali resistance, water resistance, wear resistance, oil resistance, moisture resistance, water resistance, oil resistance, dirt resistance, humidity and heat resistance, and atmospheric ageing resistance, and has excellent electrical and physical characteristics such as electrical insulation, thermal conductivity, flame resistance, stress resistance, and high bonding strength.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a wear-resistant resin adhesive. Background technique [0002] Adding fillers to adhesives can not only reduce costs, but also improve many properties of adhesives, such as improving bond strength, compressive strength and wear resistance. More fillers use quartz powder, corundum powder, talcum powder, light calcium carbonate, etc. Existing epoxy-based wear-resistant adhesives and metal filling adhesives generally add friction-reducing materials such as graphite and molybdenum disulfide and hard materials such as oxides, iron powder, and aluminum powder to epoxy resin adhesives. The existing disclosed adhesive mainly adds iron powder to improve the hardness and strength of the adhesive. The adhesive disclosed in Chinese patent CN1218100 mainly uses molybdenum disulfide to reduce friction and improve the lubricity of the coating. However, in the adhesive disclosed in Chinese ...

AI Technical Summary

Problems solved by technology

The above-mentioned adhesives formed by adding graphite, molybdenum disulfide, talc and other wear-reducing materials, oxides, iron powder and other hard materials to the epoxy resin glue are not enough to resist very harsh wear conditions and environments

[0003] Moreover, the cured products of the currently used resin adhesives are generally brittle, with poor peeling resistance, crack resistance, and impact resistance; and the adhesion to materials with low polarity (such as polyethylene, polypropylene, fluoroplastics, etc.) surface activation treatment
