Problems solved by technology

However, there are the following problems: 1. Noise problems occur during the operation of the electric slide rail of the car seat; In a low temperature environment (-25°C to -40°C), the lifting speed is slow, or even does not run; 3. After the grease is assembled on the lifter, there is a pungent smell, and the content of VOC and toxic and harmful substances exceeds the standard, etc.

Abstract

The invention relates to a low-smell composition of automobile seat electric sliderail lubricating grease and a preparation method thereof. The composition comprises the raw materials in percentage byweight: 60-65% of basic oil, 35-40% of a densifier, 0.5% of a structure modifier, 0.5% of an antioxidant and 0.5% of an antirust agent. The prepared environment-friendly automobile seat electric seatsliderail lubricating grease can effectively solve the problems that the noise generated by the slide rail in the operation process is high, the slide rail operates slowly at the low temperature, theoriginal equipment manufacturer smell and toxic and harmful substances exceed the standard by strictly controlling the variety selection of raw materials in the original formula of the product, the investigation of the adding amount and the technology in the preparation process. The lubricating grease has the excellent high and low temperature resistance, mechanical stability, colloid stability,the good antirust performance and long service life, meanwhile meets the environment-friendly and non-toxic requirements, and belongs to the low-smell lubricating material.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to the lubricating grease for an electric slide rail of an automobile seat and a preparation method thereof. Background technique [0002] With the rapid development of my country's automobile industry, the demand for automobiles has changed from first-time purchase to renewal. Automobiles no longer exist only as means of transportation. People have given automobiles more expectations and requirements: safety, environmental protection, energy saving, space Spacious and comfortable etc. The car seat is no longer a simple seat, such as adding electric heating function, automatic massage function, etc., reflecting people's pursuit of a higher quality of life. In the future, the car seat slide rail will develop in the direction of light weight, high strength, integration and platformization. Structures will also continue to be generated and applied. While constantly pursuin...
