Abstract

The invention discloses an aluminum material rolling oil additive, belonging to the lubricant composite filed. The additive comprises following substances in percentages by weight: 5-20% of C8-C14 straight-chain fatty acid, 10-30% of borate, 10-20% of zinc phosphate, and the balance of solvent. The aluminum material rolling oil additive is an environment-friendly additive, capable of satisfying aluminum rolling lubrication requirements on the condition that no other antioxidant needs to be added, has less dosage of 1-3%, and is low in cost, high in oil film strength and good in aluminum material annealing performance.

Description

technical field [0001] The present invention belongs to the field of lubricating compositions. Background technique [0002] Aluminum strip and foil rolling oil, like other lubricating oils, needs to be compounded with a certain amount of oily agents, anti-wear agents, antioxidants and other additives according to the conditions of the base oil. To achieve the purpose of lubrication, cleaning and cooling. Oily agents are long-chain fatty acids, alcohols, and esters that can physically adsorb on metal surfaces. Due to their different polarity and performance, the type and structure of additives play a key role in lubricants. Studies have shown that a single additive cannot achieve a good lubricating effect. Compound additives are often used in industry. Considering its anti-friction effect comprehensively, a good lubricant can reduce friction and significantly improve the surface quality of products; If the effect is too poor, rolling will produce obvious surface defects an...
