Water-based lubricant with favorable high-temperature antifriction property

Abstract

The invention discloses a water-based lubricant with favorable high-temperature antifriction property, which comprises the following components in parts by weight: 7-9 parts of benzoperoxide, 3-7 parts of phosphate, 25-36 parts of butyl glycidyl ether, 5-6 parts of p-chlorobenzoic acid, 15-22 parts of water-based dodecahydroxystearic acid, 5-8 parts of silane coupling agent, 13-26 parts of fatty acid amide, 35-64 parts of polytetrafluoroethylene, 3-6 parts of stearic acid, 9-17 parts of styrene, 3.5-7 parts of sodium tripolyphosphate and 65-80 parts of water. The lubricant has the advantages of favorable lubricating effect, high lengthening coefficient, environment friendliness, no pollution, simple and quick preparation method, smooth internal and external surfaces, low and cleanable residues, better high-temperature antifriction property, no smoke dust pollution and no residue, and is easy to clean.

Description

technical field [0001] The invention relates to a water-based lubricant with good anti-friction performance at high temperature. Background technique [0002] Lubrication and plastic forming are closely related. In the process of cold plastic forming of aluminum (aluminum alloy), when the aluminum to be processed and the mold move relative to each other, there is resistance between the contact surfaces that prevents tangential movement, that is, external friction. The existence of external friction will increase the force and energy required for processing, so the surface of aluminum must be lubricated. If the lubrication of the surface does not meet the requirements, it will aggravate the wear of the mold, and the phenomenon of adhesion, abrasion and scratches on the surface of the workpiece will occur. Therefore, the development of lubrication technology can promote the development of aluminum cold plastic forming. [0003] In the 1930s, the emergence of phosphating-sap...

Problems solved by technology

People try to use zinc stearate powder and animal oil as lubricants for aluminum materials with low hardness. However, zinc stearate powder seriously pollutes the workshop environment, endangers the health of operators, and adheres unevenly on the surface of aluminum materials. Difficult to control the thickness, scratches and roughening often occur; animal oil is easy to stick to the mold, and it is not easy to clean
