Abstract
The present invention provides two polyurea grease lubricant composites. One polyurea grease lubricant composite is composed of the following components of 65 to 95 % of base oil, 3 to 20 % of uramino gelatinizers, 2 to 18 % of calcium-based gelatinizers and 0 to 8 % of extreme pressure agents, and the other polyurea grease lubricant composite comprises the following components of 65 to 95 % of base oil, 5 to 30 % of uramino gelatinizers, 0.2 to 10 % of inorganic calcium salt, 0 to 5 % of calcium-based gelatinizers and 0 to 8 % of extreme pressure agents. The present invention adds calcium compounds to polyurea grease lubricant to enhance the oxidation stability of the grease lubricant without introducing antioxidant having aromaticrings, and is favorable for environment protection. Simultaneously, the introduction of the calcium compounds enhances the extreme pressure abrasion resistance of the grease lubricant.
Description
Technical field
The invention belongs to lubricating grease.
Background technology
Concerning polyurea type lubricating grease because it does not contain the metal ion that base oil is played katalysis, therefore have good oxidative stability, but at some special occasions, as high temperature, at a high speed, still need to add a certain amount of oxidation inhibitor when turning round for a long time.As, US20010002388 is exactly to add conventional oxidation inhibitor in polyurea grease, improves its oxidation stability.Sometimes, in order to reduce the cost of polyurea grease, and improve extreme pressure anti-wear, sneak into a certain amount of compound calcium therein, also will add additive in case of necessity.As, US 5,084, and 193 lubricating grease of introducing are to be mixed by calcium base viscosifying agent and polyurea thickening agent, and are added with additive, and this lubricating grease over-all properties is better.US 4,830, and 767 what introduce is to add calcium phosphate and lime carbonate in polyurea grease simultaneously, make lubricating grease have good antifriction function, but in order to improve antioxygen property, also need add a small amount of oxidation inhibitor.
CN1364859 discloses a kind of mixing thickened agent lubricant grease of high extreme pressure, is to be mixed by polyurea grease and composite calcium-base fat, extreme-pressure anti-friction additive.Described extreme-pressure anti-friction additive is to be mixed by molybdenumdisulphide, antimonous oxide, can also contain lime carbonate in the extreme-pressure anti-friction additive, can further improve the extreme pressure and antiwear behavior of lubricating grease.This lubricating grease has excellent high-temperature performance, colloid stability energy, mechanical stability energy, Corrosion Protection and excellent especially extreme pressure and antiwear behavior, but does not mention antioxygen property.
CN1414076 discloses a kind of high base number composite calcium sulfonate lubricating grease, contain organic carbamide compound that high base number calcium mahogany sulfonate or calcium alkylbenzenesulfonate, acetic acid, boric acid, hydroxy fatty acid and amine and di-isocyanate reaction generate, need add the arylamine kind antioxidant in addition.This lubricating grease has good extreme pressure, performance such as wear-resistant, anticorrosion.
In sum, the ordinary method that improves Oxidation Stability of Grease in the prior art is to add oxidation inhibitor therein, if introducing complex calcium lubricating grease or calcium containing compound then are intended to improve the extreme pressure property of lubricating grease, how not to improve oxidation stability and mention.
Summary of the invention
The present invention aims to provide two kinds of polyurea grease composites with good oxidative stability and extreme pressure and antiwear behavior.
The common feature of two kinds of grease compositions provided by the invention is to introduce calcium containing compound in polyurea grease, improves the oxidation stability energy and the extreme pressure and antiwear behavior of lubricating grease.
First kind of polyurea grease composite provided by the invention is benchmark with the composition gross weight, and be composed of the following components:
1) base oil, 65-95%, preferred 70-90%, more preferably 75-85%;
2) carbamido thickening agent, 3-20%, preferred 5-15%;
3) calcium base viscosifying agent, 2-18%, preferred 3-15%;
4) extreme pressure agent, 0-8%, preferred 0.5-5%.
Second kind of polyurea grease composite provided by the invention is benchmark with the composition gross weight, comprising:
1) base oil, 65-95%, preferred 70-90%, more preferably 75-85%;
2) carbamido thickening agent, 5-30%, preferred 8-25%;
3) inorganic calcium salt, 0.2-10%, preferred 0.5-6%;
4) calcium base viscosifying agent, 0-5%, preferred 1-3%;
5) extreme pressure agent, 0-8%, preferred 0.5-5%.
Said base oil is 100 ℃ of lubricating oil that viscosity is 10-20cSt, comprises mineral oil, vegetables oil or synthetic oil, for example 100SN-500SN Dormant oils, ester class oil, poly ﹠ Alpha ,-olefin oil, vegetable seed wet goods.
Said carbamido thickening agent is by C
