阅读说明：本技术 除油除锈磷化三合一皮膜剂、钢铁件及其皮膜化处理方法 (Oil-removing, rust-removing and phosphorizing three-in-one coating agent, steel part and leather membranization treatment method thereof ) 是由 方招娣 于 2017-07-04 设计创作，主要内容包括：一种除油除锈磷化三合一皮膜剂、钢铁件及其皮膜化处理方法。除油除锈磷化三合一皮膜剂用于钢铁件表面预处理,以2000重量份计,包括如下重量份数的成分：50-100份磷酸,10-30份硝酸锌,1-6份硫酸钙,4-15份冰醋酸,1-5份氯化镁,2-6份烷基聚氧乙烯醚,1-6份硝酸镍,余量的水。上述除油除锈磷化三合一皮膜剂能同时去除油污、锈迹,并且形成的膜层,膜层结构细致,附着力牢固,能在钢钢铁表面上生成灰色的皮膜,具有良好防腐性、并且能提高后续涂层的附着力。(An oil-removing rust-removing phosphorizing three-in-one coating agent, a steel part and a coating treatment method thereof. The three-in-one coating agent for oil removal, rust removal and phosphorization is used for surface pretreatment of steel parts and comprises the following components in parts by weight in 2000 parts by weight: 50-100 parts of phosphoric acid, 10-30 parts of zinc nitrate, 1-6 parts of calcium sulfate, 4-15 parts of glacial acetic acid, 1-5 parts of magnesium chloride, 2-6 parts of alkyl polyoxyethylene ether, 1-6 parts of nickel nitrate and the balance of water. The oil-removing rust-removing phosphating three-in-one coating agent can simultaneously remove oil stains and rust stains, and the formed coating has a fine structure and firm adhesive force, can generate a gray coating on the surface of steel, has good corrosion resistance, and can improve the adhesive force of a subsequent coating.)
