Epoxy Resin Has Good Heat Resistance

Aug 01, 2020

Epoxy resin is widely used in the fields of adhesives, sealants and coatings due to its good heat resistance, high strength and good adhesion to the substrate. In addition, because it not only has excellent wear resistance and acid and alkali resistance, but also has the advantages of simple coating process and low cost, it is widely used in the coating of corrosion-resistant and wear-resistant surfaces of parts, repair of defects on workpieces, and corrosion and wear Surface repair, but epoxy resin also has the shortcomings of high brittleness, resulting in poor impact resistance, peeling resistance and vibration fatigue resistance. In this paper, the friction and wear properties of EP coating under dry friction and water, 300# liquid paraffin lubrication were studied, and the wear mechanism of the polymer was analyzed.
