一种天然气/凝析液管道内壁用减阻防腐涂料及其制备方法
摘要：
本发明公开了一种天然气/凝析液管道内壁减阻防腐涂料及其制备方法。该涂料由质量比为(2-4)∶1的组分A和B组成，所述组分A组成如下：液态有机硅树脂5～30，液态环氧树脂30～55，增韧剂1～15，流平剂0.1～2，消泡剂0.1～1.5，分散剂0.05～1.5，偶联剂0.1～2，防沉剂0.0～2，颜料0～15和填料10～60；组分B组成如下：改性多元胺类固化剂40～70，酚醛树脂固化剂5～35，分散剂0.5～2.5，防沉剂0.5～2.5，和填料15～50；所述涂料中组分A和B采用二元包装。该涂料在50℃下具有良好的抗高压天然气或气液失压起泡、抗剪切、粘结强度高、耐磨性好、抗天然气凝析液的腐蚀、涂层光滑致密、无溶剂、快干等优点，适合于内减阻、防腐和耐磨环境下的工矿要求。
摘要（英）：

The invention discloses an anti-drag and anticorrosion coating for an inner wall of a natural gas/condensed liquid pipeline and a preparation method thereof. The coating comprises an ingredient A and an ingredient B according to a mass ratio of (2-4):1, wherein the ingredient A comprises the following ingredients in parts by mass: 5-30 parts of liquid organic silicon resin, 30-55 parts of liquid epoxy resin, 1-15 parts of flexibilizer, 0.1-2 parts of leveling agent, 0.1-1.5 parts of defoaming agent, 0.05-1.5 parts of dispersing agent, 0.1-2 parts of coupling agent, 0.0-2 parts of anti-settling agent, 0-15 parts of pigment and 10-60 parts of filler; the ingredient B comprises the following ingredients in parts by mass: 40-70 parts of modified polyamine curing agent, 5-35 parts of phenolic resin curing agent, 0.5-2.5 parts of dispersant, 0.5-2.5 parts of anti-settling agent and 15-50 parts of filler; and the ingredient A and the ingredient B in the coating are packaged in a binary manner. The coating has the advantages of good resistance to high pressure natural gas or gas-liquid decompression and bubbling, shear resistance, high bonding strength, good wear resistance, resistance to corrosion of natural gas condensed liquid, smoothness and compactness of the coating, no solvent, quick drying and the like below 50 DEG C, and is suitable for mining requirements under anti-drag, anticorrosion and wear-resistant environments.
