Abstract

The invention belongs to the field of lubricants, particularly relates to a polyisobutene lubricant, and provides the following scheme aiming at the problem of poor temperature resistance of existing lubricating oil. The high-temperature-resistant insulating material is prepared from the following raw materials in parts by weight: 40 to 50 parts of polyisobutene, 5 to 10 parts of graphite powder, 10 to 15 parts of silicone oil, 1 to 5 parts of polyvinyl alcohol, 0.5 to 1 part of oxalic acid diester, 0.5 to 1 part of di-iso-decyl phthalate, 0.1 to 0.5 part of vinyl ester resin, 0.5 to 1 part of octadecyl thiodipropionate, 0.1 to 0.5 part of calcium glycerophosphate, 1 to 5 parts of calcium stearate, 0.3 to 0.7 part of polyimide, 0.4 to 0.8 part of N-phenylmaleimide, 0.1 to 0.5 part of 2-hydroxy-4-methoxybenzophenone, 0.5 to 1 part of distearyl thiodipropionate and 0.1 to 0.5 part of resorcinol monobenzoate. According to the present invention, the polyisobutylene lubricant has advantages of excellent temperature resistance and simple preparation method.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a polyisobutylene lubricant. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. It is divided into : Industrial lubricants, medical surgical equipment lubricants, human body lubricants, the main function is to reduce the friction damage of the friction surface. However, due to the wide range of industrial machinery, the requirements of various machinery for lubricating oil are mainly to meet the requirements of reducing friction and wear, and there are also some special requirements that are put forward according to different working environments and working conditions. Divided into: automotive lubricants; industrial lubrican...
