Abstract
- Aiming at the corrosion and abrasion of the inner wall of the steam pipes caused by the piston wear under the high temperature of 150 ℃, based on the solvent-free epoxy resin system, a temperature-resistant and wear-resistant epoxy coating applicable to the inner wall of steam pipes with good comprehensive performance was developed through the selection of filler, additives, and the design of formula. The coating adopted a resin system modified by blending E-031 alicyclic epoxy resin and J-129 phenolic epoxy resin, and selected PTFE as the lubricating filler. Moreover, the effect of its different particle size and dosage on the wear resistance of the coating was researched, and it could be found that the wear resistance of the coating was better when the amount of PTFE powder with a particle size of 2 μm was 7%(mass fraction, the same below). Meanwhile, through the screening of silane coupling agent and the research of performance, the optimal dosage of KH-560 was determined as 1.5%, and finally a solvent-free, temperature-resistant and wear-resistant epoxy coating with good comprehensive performance meeting the use requirements was prepared.
