Problems solved by technology

[0003] A kind of aluminum material rolling oil composite additive in the related art, this additive is mainly composed of C 8 -C 14 Composed of straight-chain fatty acids and octyl borate, since fatty acids and metal surfaces are more chemically adsorbed than physically adsorbed, and the activation energy required for chemical adsorption is at least 10 times that of physical adsorption, so in the actual annealing process, These substances will remain on the surface of the aluminum material, resulting in poor annealing cleanliness, easy to cause product quality problems such as black spots and black spots on the surface of the aluminum material, and at the same time increase the energy consumption of annealing; in addition, the addition of sulfur and phosphorus anti-wear agents, The volatilization effect is affected, and the oil spots on the surface of the aluminum are serious after annealing. It is necessary to prolong the annealing time, increase the annealing temperature, and further increase the energy consumption
Therefore, the composite additives for aluminum rolling in the related art have the disadvantages of poor annealing cleanability, low surface quality of annealed products, and high annealing energy consumption.

Abstract

The invention provides an aluminum rolling composite additive which is prepared from, by mass, 65.0-79.0% of mixed alcohol additives, 15.0-25.0% of mixed fatty alcohol acid ester additives and 6.0-12.0% of aluminum rolling base oil. The mixed alcohol additives are prepared from, by mass, 15.0-25.0% of n-decyl alcohol, 28.0-38.0% of dodecanol and 40.0-50.0% of myristyl alcohol. The mixed fatty alcohol acid ester additives are prepared from, by mass, 70.0-80.0% of tetradecanoic acid-methyl ester and 20.0-30.0% of methyl palmitate. Compared with the prior art, the aluminum rolling composite additive has the advantages of being good in annealing detergency, high in annealing product surface quality and low in annealing energy consumption.

Description

【Technical field】 [0001] The invention relates to the technical field of lubricating compositions, in particular to a composite additive for aluminum rolling. 【Background technique】 [0002] The rolling oil used for aluminum materials (such as aluminum plates, strips, foils) needs to add a certain amount of additives such as oily agents, anti-wear agents, and antioxidants according to the conditions of the base oil to achieve lubrication, cleaning, and cooling. Purpose. However, 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 the product; If the effect is too poor, rolling will produce obvious surface defects and reduce the surface quality. At the same time, its annealing performance should also be considered to maintain the cleanliness of the surface of the aluminum strip. Th...
