High-temperature chain lubricant and preparation method thereof

Abstract

The invention discloses a high-temperature chain lubricant and a preparation method thereof. The high-temperature chain lubricant comprises the following raw materials in parts by weight: 10-30 parts of polydimethyl terephthalate, 20-80 parts of polyvinyl pyridine, 60-100 parts of vinyl acetate, 10-50 parts of zinc sulfide, 40-60 parts of p-phenylenediamine, 70-100 parts of zinc barium stabilizer, 10-20 parts of phellodendrine, 10-20 parts of magnoline, 5-20 parts of silane coupling agent, 6-10 parts of kaolin powder, 40-60 parts of defoamer and 40-80 parts of modifier. The preparation method comprises the following steps: uniformly mixing the polydimethyl terephthalate, polyvinyl pyridine, vinyl acetate, zinc sulfide and p-phenylenediamine, heating to react, and cooling; adding the zinc barium stabilizer, phellodendrine, magnoline, silane coupling agent and kaolin powder, and heating to react; and cooling, adding the defoamer and modifier and stirring uniformly. The melting point is 309-318 DEG C; and the high-temperature chain lubricant has the advantages of favorable high temperature resistance and stable properties, and is slightly influenced by the temperature change.

Description

technical field [0001] The invention belongs to the field of chain lubricating oil, in particular to a high-temperature chain lubricating agent and a preparation method thereof. Background technique [0002] Chain lubricants are lubricating media used to reduce the frictional resistance of friction pairs and slow down their wear. Lubricants can also cool, clean and prevent pollution on the friction pair. In order to improve the lubricating performance, suitable additives can be added to some lubricants. When selecting a lubricant, it is generally necessary to consider many factors such as the movement of the friction pair, the material, the surface roughness, the working environment and working conditions, and the performance of the lubricant. In mechanical equipment, lubricants are mostly delivered to the parts that need to be lubricated through the lubrication system. Depending on the source, there are mineral lubricants (such as machine oil), vegetable lubricants (suc...

Problems solved by technology

However, the lower the viscosity index of the lubricating oil, the greater the viscosity of the lubricating oil with the change of temperature during use. The performance of the lubricating oil may change at high temperature, which will affect the final use effect.
