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 weight percentage: fatty alcohol polyoxyethylene polyoxypropylene 1-10%, N-formazol Morpholine 0.2~0.6%, sodium polyacrylate 1~5%, reverse block polyether 1~5%, hydrogenated oil 5~20%, antioxidant 0.1~0.5%, and the balance is base oil. The protective lubricant obtained in the present invention, on the one hand, has excellent temperature thixotropy, it is in a condensed state when it is lower than 40°C, it is a liquid when it is higher than 45°C, and it is a semi-condensed state at 40‑45°C; it is excellent on the surface of an aluminum plate. Excellent adsorption, protection and lubricity, no sagging at room temperature, high oil film strength, good retention, good anti-friction and anti-sticking effects, does not affect the operating environment, and the surface of the aluminum plate does not produce discoloration and other corrosion phenomena under high temperature and high humidity; On the other hand, it has excellent cleanability, meets the degreasing requirements of automotive customers, and does not affect subsequent surface treatment and electrophoresis.

Description

technical field [0001] The invention belongs to the technical field of metal protection, and in particular relates to a protective 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 sticking to aluminum, lubricants are often used for process lubrication. However, with the vigorous development of aluminum plate cold rolling production, rolling equipment is advancing day by day, and the need for rolling process lubricants The requirements are also getting higher and higher. At present, there are a variety of lubricants on the market, with mixed reviews. Although they all have a certain lubricating performance, the lubricating effec...
