Problems solved by technology

[0002] Lubricating oil additives are one or several compounds added to lubricants to make the lubricant acquire some new characteristics or improve some existing characteristics of the lubricant. The additives in the market are generally the compound of the above single additives The only difference is that the composition of the single additive is different and the ratio of several single additives in the composite additive is different. There are many kinds of existing additives, some of which cannot resist oxidation and wear well, and some have more foam , can not effectively prevent corrosion and rust, and some can not improve the viscosity index

Abstract

The invention discloses a lubricant additive. The lubricant additive comprises the following substances in parts by weight: 1-3 parts of petroleum sulfonate, 2-7 parts of polyisobutene boride succinimide, 1-4 parts of alkali dioctylalkyl zinc thiophosphate, 2-10 parts of tetrabutylammonium bromide, 3-9 parts of N, N-dimethylformamide, 1-8 parts of isobutenyl sulfide, 5-10 parts of paraffin, 3-13 parts of polyacrylic acid, 2-8 parts of dodecyl benzene sulfonate and 10-20 parts of dimethicone. The lubricant additive has the benefits as follows: the lubricant additive is convenient to use and low in manufacturing cost, can resist oxidation and abrasion better, has moderate foams, can effectively resist corrosion and rustiness, can improve the viscosity index better and improve the quality of a lubricant.

Description

technical field [0001] The invention relates to a lubricating oil additive. Background technique [0002] Lubricating oil additives are one or several compounds added to lubricants to make the lubricant acquire some new characteristics or improve some existing characteristics of the lubricant. The additives in the market are generally the compound of the above single additives The only difference is that the composition of the single additive is different and the ratio of several single additives in the composite additive is different. There are many kinds of existing additives, some of which cannot resist oxidation and wear well, and some have more foam , cannot effectively prevent corrosion and rust, and some cannot improve the viscosity index well. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lubricating oil additive. [0004] In order to solve the above-mentioned technical problems, the technical solut...
