preparation example Construction

[0041] The invention provides a kind of preparation method of lubricant, comprises the following steps:

[0042] Heat polyisobutylene to 80-110°C. For example, it can be heated to 95°C first, add aviation kerosene and mix well, then add silicone oil, mix well and then add petrolatum, mix well and cool down to obtain lubricant, which can be cooled to room temperature and then sealed Preserve, can not add petrolatum in lubricant; Wherein, aviation kerosene and polyisobutene can be 10 weight parts, and the weight ratio of aviation kerosene and polyisobutylene can be (3-8):1, and silicone oil can be 2-5 weight Parts, petrolatum can be 0-2 parts by weight. In the preparation process, when selecting equipment, you can choose a furnace with a temperature of more than 20L and a heating temperature of 200°C, and the stirring rod can be made of steel or wood.

[0043] Optionally, the number average molecular weight of polyisobutylene can be 4000-60000, and the molecular weight of silic...

Embodiment 1

Abstract

The invention provides a lubricant and a preparation method thereof. The lubricant comprises in parts by weight: 10 parts of aviation kerosene and polyisobutylene; 2-5 parts of silicone oil; and 0-2 parts of petrolatum, wherein the weight ratio of aviation kerosene and polyisobutylene is (3-8):1. In the lubricant preparation process, polyisobutylene is heated to 80-110 DEG C, aviation kerosene isadded and evenly mixed, then silicone oil is added and evenly mixed, then petrolatum is added and evenly mixed, and cooling is carried out to obtain the lubricant. The lubricant has good lubricating effect, the lubricant is used between a skylight glass and a rubber strip, and between a rubber strip and a rubber strip, the frictional force between the skylight glass and the rubber strip, and between the rubber strip and the rubber strip can be reduced, the friction sound is reduced, the sound generated by a skylight can be eliminated, the sealing property at a joint is enhanced, the high-temperature or low-temperature resistance is good, and the preparation process is simple.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a lubricant and a preparation method thereof. Background technique [0002] The existing sunroof is a necessary configuration function for cars, but generally there will be different degrees of friction sound between the glass of the sunroof and the rubber strips, and between the rubber strips. At present, there are two mainstream ways to reduce the friction sound. One method is to use different materials to increase the friction between the sunroof glass and the rubber strips, and between the rubber strips and the rubber strips. The other method is to reduce the friction by increasing the Lubricants are used to reduce friction and reduce friction sound, but the existing lubricants have poor lubricating effect, low ability to withstand high temperature or low temperature, and the lubricating effect is reduced in high temperature or low temperature environments, which is not conducive to...
