耐高温的热喷涂封孔剂及其使用方法
摘要：
本发明是一种耐高温的热喷涂封孔剂，该封孔剂的化学成分的重量份数为：树脂58-62份、填料4-8份、溶剂22-28份、固化剂16-22份，粒径40-60μm铝粉8-12份，氧化铈1-4份，分散剂6-8份；粘接助剂2-6份；所述溶剂为丙酮和乙烯乙二醇醚以体积比3:2混合的混合溶剂；所述的固化剂为二乙烯三胺、间苯二胺、酚醛改性胺、二氨基二苯基甲砜DDS中的一种；所述填料按二氧化硅：重钙粉：氧化锆=5:1:3的重量份数比例混合。本发明提供的封孔剂具有良好的渗透性和稳定性，而且抗磨损、耐高温腐蚀和抗酸液腐蚀等性能显著提高。
摘要（英）：

The invention discloses a high-temperature-resistant thermal spraying hole sealing agent. The hole sealing agent comprises the following chemical constituents in parts by weight: 58 to 62 parts of resin, 4 to 8 parts of a filler, 22 to 28 parts of solvent, 16 to 22 parts of a curing agent, 8 to 12 parts of aluminum powder with the particle size being 40 to 60 [mu]m, 1 to 4 parts of cerium oxide, 6 to 8 parts of a dispersing agent, and 2 to 6 parts of a bonding auxiliary agent, wherein the solvent adopts mixed solvent of acetone and ethylene glycol ether with the volume ratio of 3:2; the curing agent adopts one of diethylenetriamine, metaphenylene diamine, phenolic modified amine, diaminodiphenyl methyl sulphonyl DDS; the filler is mixed from 5 parts of silicon dioxide, 1 part of heavy calcium powder and 3 parts of zirconium oxide by weight. The hole sealing agent has good penetrability and stability, and obviously improves the abrasion resistance, high temperature corrosion resistance and acid liquor corrosion resistance.
