Problems solved by technology

[0010] In view of the deficiencies in the prior art, the purpose of the present invention is to propose a composite high-pressure additive for aluminum cold rolling to solve the problem of insufficient oil lubrication under large rolling forces during cold rolling of aluminum sheets, strips and foils. The product still maintains good lubricating properties, and at the same time ensures the requirements of the annealed surface quality of aluminum

Embodiment 1

[0038] Example 1: Screening of extreme pressure antiwear agents

[0039] Select different extreme pressure antiwear agents, and cooperate with alcohol ester additives, antioxidants, and base oils to test annealing oil spots and judge regression grades. The antioxidant used in the present embodiment is BHT, and structural formula is as follows:

[0040]

[0041] Higher fatty acid esters are C12 fatty acid esters and C12 fatty alcohols In the aluminum cold rolling composite high-pressure additive, the mass percentages of extreme pressure antiwear agent, higher fatty acid ester, higher fatty alcohol, antioxidant, and base oil are 40%, 5%, and 5%, respectively, 0.5%, and the balance is base oil. Aluminum cold rolling composite high-pressure additives were mixed with aluminum rolling oil additives and base oil (the amount added in Table 2 is parts by mass), and the oil film strength and annealing oil spots were tested. The results are shown in Table 2.

Abstract

The invention belongs to the field of lubricant compositions, and provides an aluminum cold rolling composite extreme pressure additive. The aluminum cold rolling composite extreme pressure additive comprises, by mass, 25-50% of an extreme pressure anti-wear agent, 4-10% of high fatty acid ester, 4-10% of higher aliphatic alcohol, 0.5-3% of an antioxidant and 30-55% of base oil. 1-5 Parts of the composite extreme pressure additive is added to the rolling oil, and 5-8 parts of an aluminum rolling oil additive and base oil are combined, so the integral lubrication performance of the rolling oil is improved without changing the original process, the strength of an oil film is increased obviously, the rolling lubrication ability in the strip and foil processing process under a large reduction condition is guaranteed, and the annealing oil stain condition is good.

Description

technical field [0001] The invention belongs to the field of lubricating compositions, and in particular relates to a lubricating agent composition containing aliphatic additives, a preparation method and application thereof. Background technique [0002] With the continuous development of the aluminum cold rolling processing industry, high-speed, large reduction, and multi-stand rolling mills have emerged, while rolling aluminum sheets, strips and foils with large rolling forces and large reductions, aluminum rolling oil often has insufficient bearing capacity In addition, the deformation heat and friction heat of the alloy during rolling make the temperature of the rolling mill, the rolled piece and the oil product continuously increase. At this time, the aluminum rolling oil product will also have insufficient lubrication. The reason is mainly due to the aluminum rolling The oil that plays a decisive role in the bearing capacity is the aluminum rolling oil additive. At pr...
