Abstract

The invention discloses an aluminum rolling oil additive composition, the present invention is characterized in that the composition comprises the following components by mass percentage: (1) oiliness agent: 30 to 48%; (2) antiwear agent containing phosphorus: 3 to 15%; (3) oleamide: 26 to 35%; (4) de-emulsifier: 0.5 to 2.8%; (5) phenolic antioxidants: 0.1 to 0.5%; (6) hydrogenated base oil: the balance. The oiliness agent is monoolein and / or oleic acid; the antiwear agent containing phosphorus is one or more selected from amine sulfuric-phosphoric diester, phosphorothioate and its amine salt, phosphate ester and its amine salt; the de-emulsifier is a combination of two types non-ionic high-molecular surfactants. According to the invention, an antiabrasive agent oleamide and the phosphatide antiwear agent are combinated with aliphatic acid and fatty acid ester, which achieves the goal of reducing the friction coefficient and improving the annealing performance; and the application amount of the additive and the cost of aluminum rolling oil can be reduced.

Description

technical field [0001] The invention relates to an additive composition, in particular to an aluminum material rolling oil additive composition. Background technique [0002] Aluminum rolling oil is mainly composed of appropriate mineral base oil and modified compound additives. Because the oil film formed by the base oil and the metal surface only produce physical adsorption, the adsorption force is small, and the lubricity is poor, so it is necessary to add additives to the base oil on industrial rolled aluminum to improve the boundary lubrication ability of the oil film. Additives are polar compounds or polymers that can improve certain properties of oil products. It is one of the most economical and effective ways to improve the lubricating properties of mineral base oils. [0003] The main additives in aluminum oil are oily agents, which can physically adsorb long-chain fatty acids, alcohols, and esters with the metal surface. Due to their different polarity and perfor...
