Graphite lubricant with good high temperature adhesion

Abstract

The present invention discloses a graphite lubricant with good high temperature adhesion, the graphite lubricant is prepared from the following raw materials in parts by weight: 25-35 parts of petroleum ether, 4-8 parts of absolute ethanol, 5-9 parts of engine oil, 0.2-0.4 part of calcium salicylate, 1-2 parts of ethylene bis stearamide, 2-4 parts of polyethylene wax, 2.5-4 parts of nano-graphite, 3-5 parts of sodium gluconate, 1-2 parts of polyacrylamide, 1-2 parts of toluene diisocyanate, 4-9 parts of methyl isobutyl ketone and 15-25 parts of modified graphite powder; the graphite lubricant is reasonable in raw material distribution, both can ensure good low-temperature film forming performance, also ensures good high temperature adhesion and suspension dispersion property, and has high temperature resistance, high contact pressure resistance and adequate load wear-resisting capacity, the manufacturing process can meet the needs of aluminum extrusion, the cost is moderate, and the performance cost ratio is high.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a graphite lubricant with good high-temperature adhesion. Background technique [0002] The non-lubricated extrusion process was gradually replaced by the lubricated extrusion process, and a special extrusion lubrication technology was formed. The lubrication technology has been widely used in the processing and production of aluminum profiles. [0003] More than 99% of the extruders in my country use the movable extrusion pad technology. The starting point is that the extrusion pad cannot be 100% guaranteed to be separated from the residual pressure. In order to make the extrusion process continuous, one extrusion machine is equipped with several extrusion pads. Pads, work in turn. In the production of building profiles, a lubricant is often applied to the end surface of the movable extrusion pad in contact with the pressure residue, which is conducive to the smooth separation of the e...

Problems solved by technology

[0004] The traditional aluminum profile extrusion lubricant in our country is rapeseed oil plus graphite, not only the separation effect is not ideal, it is not heat resistant, and only one ingot can be extruded at a time, and the smoke is too thick, the fire is too big, pollutes the environment, and seriously harms Safe Production
