Abstract

An improved lubricating grease additive is composed of the following raw materials in parts by weight: 6 to 10 parts of ethyl acrylate, 8 to 11 parts of methyl silicone oil, 5 to 7 parts of polyvinyl alcohol, 1.2 to 3 parts of ZDDP-T203, 7 to 10 parts of isooctyl phosphate, 1.3 to 2.7 parts of glyceride, 3 to 10 parts of sulfurized calcium alkyl phenolate, 3.2 to 5 parts of bis(salicylidene) propane diamine, 3 to 6 parts of phenothiazine, 1.2 to 3 parts of soap base, 4 to 7 parts of polyisobutylene succinimide, 6 to 11 parts of dimethyl acetamide, 8 to 10 parts of hydrogenated carbonyl phenol, and 6 to 10 parts of silicone oil. The provided improved lubricating grease additive can well improve the cooling and lubricating effect of lubricating grease and has the advantages of low cost and user-friendliness at the same time.

Description

A kind of grease additive of improvement

Technical field

The present invention relates to a kind of grease additive of improvement.

Background technology

The use of current lubricating grease is because its specific semi-solid state, and lubricating grease is easier than lubricating oil to be sealed in bearing, therefore, in use needs additive to improve the performance of lubricating grease.It is an increasing trend that grease additive add-on can progressively improve, and grease additive consumption will inevitably correspondingly increase.Simultaneously mechanical means constantly progress, grease product updates, and all needing provides the performances such as antioxygen, antirust, extreme-pressure anti-wear by additive.The additive effectiveness comparison sold in market is single, and over-all properties is poor, well can not meet the use properties of lubricating grease.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of grease additive, and can be good at the cooling, the lubricant effect that improve lubricating grease, cost is low, easy to use simultaneously.

For solving prior art problem, technical scheme provided by the invention is, a kind of grease additive of improvement, and it is made up of the raw material of following parts by weight:

Ethyl propenoate 6-10 part, methyl-silicone oil 8-11 part, polyvinyl alcohol 5-7 part, the two pungent primary alkyl zinc salt 1.2-3 part of sulphur phosphorus, isooctyl phosphoric acid ester 7-10 part, glyceryl ester 1.3-2.7 part, calcium sulfenyl phenolate 3-10 part, two salicylidene propylene diamine 3.2-5 part, thiodiphenylamine 3-6 part, soap base 1.2-3 part, polyisobutene succinimide 4-7 part, N,N-DIMETHYLACETAMIDE 6-11 part, phenol of hydrogenized carbonyl 8-10 part, silicone oil 6-10 part.

The invention has the beneficial effects as follows: grease additive of the present invention, can be good at the cooling, the lubricant effect that improve lubricating grease, cost is low, easy to use simultaneously.
