Abstract

The invention relates to a preparation method for a gear oil composite additive. The gear oil composite additive is basically characterized by comprising, by weight, 6-8% of a rusting inhibitor; 8-10% of an antiwear additive; 4-6% of an extreme pressure additive; 4-5% of a solid extreme pressure additive;7-8% of a demulsifying agent; 7-9% of a foam inhibitor; 4-5% of a viscosity index improver; 4-5% of a metal deactivator; 6-7% of boron powder; 4-6% of metal magnesium powder; and the balance base oil. Being economical and practical, the gear oil composite additive provided by the invention has the advantages of simple preparation scheme, strong thermal stability, good high temperature extreme pressure performance, strong oxidation resistance and high wear resistance, can prolong the demulsification life, and can enhance the anti-blistering performance, and the comprehensive performance is stronger than that of similar products. The waste oil can be degradable, thus enhancing the environmental protection requirements.

Description

(1) Technical field [0001] The invention relates to a gear oil additive, in particular to a preparation method of a gear oil compound additive. (2) Background technology [0002] With the continuous progress of mankind and the development of science and technology, the reform and innovation of various mechanical equipment have put forward higher requirements for the use of various lubricating oils and various lubricating oil additives. In terms of gear oils, scientists are working hard to improve the efficiency of transmissions in order to provide end users with lower operating costs. But this results in higher gear speeds and loads, as well as higher fluid operating temperatures. And the existing gear oil urgently needs to improve the following problems: [0003] 1. Higher change thermal stability. [0004] 2. Improve the extreme pressure performance at high temperature. [0005] 3. Improve oxidation resistance. [0006] 4. Extend the life of demulsibility. [0007] 5...
