一种精密铸造件防锈油及其制备方法
摘要：
本发明公开了一种精密铸造件防锈油及其制备方法，涉及铸造业技术领域，由如下重量份数的原料制成：芳烃改性萜烯树脂5‑10份、超细氧化镁负载氢化松香甘油酯3‑5份、三羟甲基丙烷三缩水甘油醚2‑3份、预胶化淀粉2‑3份、氢化蓖麻油1‑2份、分子筛原粉‑泊洛沙姆复合物1‑2份、交联聚维酮0.5‑1份、双季戊四醇0.5‑1份、双丙酮丙烯酰胺0.3‑0.5份、纳米胶粉0.05‑0.1份、120号溶剂油100‑150份。本发明防锈油均匀附着于精密铸造件表面后形成厚度低至0.2mm的超薄防锈保护层，以有效隔绝空气中的氧气和水分以及其他腐蚀性物质对铸造件表面造成的锈蚀。
摘要（英）：

The invention discloses anti-rust oil for a precision casting and a preparation method thereof and relates to the technical field of foundry industry. The anti-rust oil is prepared from the following raw materials in parts by weight: 5 to 10 parts of aromatic hydrocarbon modified terpene resin, 3 to 5 parts of super-fine magnesium oxide loaded hydrogenated rosin glyceride, 2 to 3 parts of trimethylolpropane triglycidyl ether, 2 to 3 parts of pre-gelatinized starch, 1 to 2 parts of hydrogenated castor oil, 1 to 2 parts of a molecular sieve raw powder-poloxamer complex, 0.5 to 1 part of polyvinylpolypyrrolidone cross-linked, 0.5 to 1 part of dipentaerythritol, 0.3 to 0.5 part of diacetone acrylamide, 0.05 to 0.1 part of nano-micelle powder and 100 to 150 parts of 120# solvent oil. The anti-rust oil disclosed by the invention is uniformly attached to the surface of the precision casting to form an ultra-fine anti-rust protection layer with the thickness as thin as 0.2mm, so that rust, caused by oxygen and water in the air and other corrosive substances, on the surface of the casting is effectively isolated.
