Abstract

The invention is applicable to the technical field of metal protection, and provides a protective lubricant and a preparation method thereof. The protective lubricant comprises the following raw materials in percentage by weight: 1-10% of fatty alcohol-polyoxyethylene polyoxypropane, 0.2-0.6% of N-methylmorpholine, 1-5% of sodium polyacrylate, 1-5% of reverse embedded polyether, 5-20% of hydrogenated grease, 0.1-0.5% of an antioxidant and the balance of base oil. On one hand, the obtained protective lubricant has excellent temperature thixotropic property, is in a condensed state when the temperature is lower than 40 DEG C, is in a liquid state when the temperature is higher than 45 DEG C, and is in a semi-condensed state when the temperature is 40-45 DEG C; excellent adsorbability, protective property and lubricating property are achieved on the surface of an aluminum plate, sagging is avoided at normal temperature, the oil film strength is high, the retentivity is good, the antifriction and anti-sticking effects are good, the operation environment is not influenced, and the surface of the aluminum plate does not generate corrosion phenomena such as discoloration under high temperature and high humidity; and on the other hand, excellent cleanability is achieved, the degreasing requirement of automobile customers is met, and subsequent surface treatment, electrophoresis and thelike are not affected.

Description

Technical field [0001] The invention belongs to the technical field of metal protection, and particularly relates to a protection lubricant and a preparation method thereof. Background technique [0002] Aluminum and its alloys are important basic materials for the development of my country's national economy, and are widely used in aviation, aerospace, construction, printing, transportation, electronics, chemicals, food, medicine and other industries. [0003] When aluminum and its alloys are cold rolled, in order to prevent aluminum sticking, lubricants are often used for process lubrication. However, with the vigorous development of aluminum plate cold rolling production, rolling equipment is constantly advancing with each passing day, and the use of lubricants for rolling process The requirements are getting higher and higher. At present, there is a dazzling array of lubricants on the market with mixed reviews. Although they can provide certain lubricating performance, the lub...
