Abstract

The invention relates to a composite additive used for industrial gear oil. The composite additive is basically characterized by comprising, by weight, 7-9% of an antioxidant; 6-8% of an anti-abrasion agent; 5-6% of a metal deactivator; 5-7% of an antiwear agent; 4-6% of an extreme pressure agent; 8-10% of a demulsifying agent; 4-5% of a friction modifier; 5-7% of a pour point depressant; 8-10% of a foam inhibitor; 8-10% of metal magnesium powder; 4-6% of graphite, and the balance base oil. Being economical and practical, the composite additive used for industrial gear oil provided by the invention has the advantages of simple preparation scheme, strong thermal stability, good high temperature extrusion performance, strong oxidation resistance, and high wear resistance, can prolong the demulsibility life, also can enhance the anti-foaming performance, and has comprehensive performance superior to that of similar products. The waste oil is degradable, thus improving the environmental protection requirements.

Description

(1) Technical field [0001] The invention relates to a compound additive for industrial gear oil, in particular to a preparation scheme and a preparation method of the compound additive for industrial gear oil. (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 resi...
