Embodiment 1

[0025] 5g polytetrafluoroethylene powder is joined in 5g perfluoropolyether oil (the structural formula of perfluoropolyether oil is formula (I), wherein R f1 For—CF 3 , R f2 for-C 2 f 5 , m=36, n=2; 20°C kinematic viscosity is 60cSt), stirred at room temperature for 30min at a speed of 100±10r / min, then added the obtained mixture and 90g of ethyl perfluorobutyl ether solvent to In the dispersion kettle, stir at a speed of 200±10r / min for 45min, add an empty tank for filling to obtain the product, and the performance characteristics of the product are shown in Table 1.

Embodiment 2

[0027] The chlorotrifluoroethylene-polyethylene powder of 5g is joined in the 5g perfluoropolyether oil (the structural formula of perfluoropolyether oil is formula (II), wherein R f1 For—CF 3 , R f2 for-C 3 f 7 , m=65, n=4; kinematic viscosity at 20°C is 135cSt), stirred at room temperature for 30min at a speed of 100±10r / min, then added the obtained mixture and 90g of ethyl perfluorobutyl ether solvent to In the dispersion kettle, stir at a speed of 200±10r / min for 45min, add an empty tank for filling to obtain the product, and the performance characteristics of the product are shown in Table 1.

Embodiment 3

[0029] The polytetrafluoroethylene powder of 3g is joined in the perfluoropolyether oil of 8g (the structural formula of perfluoropolyether oil is formula (II), wherein R f1 For—CF 3 , R f2 for-C 3 f 7 , m=70, n=5; 20°C kinematic viscosity is 164cSt), stirred at room temperature for 30min at a speed of 100±10r / min, then added the obtained mixture and 89g of methyl perfluorobutyl ether solvent to In the dispersion kettle, stir at a speed of 200±10r / min for 45min, add an empty tank for filling to obtain the product, and the performance characteristics of the product are shown in Table 1.

Abstract

The invention provides a perfluoropolyether lubricant and a preparation method thereof. The perfluoropolyether lubricant comprises, by weight, 2-15% of perfluoropolyether oil and 80-98% of a fluorine-containing solvent. The perfluoropolyether lubricant has the advantages of very simple formula, low cost, and easiness in industrial production; and the lubricant contains no solid lubricant components, so the lubricant is very suitable for lubricating the micro-electromechanical system.

Description

technical field [0001] The invention belongs to the technical field of lubrication of micro-electromechanical systems, and in particular relates to a perfluoropolyether lubricant and a preparation method thereof. Background technique [0002] With the development of modern industry, there are more and more friction pairs of automation and mechanization products, and the requirements for friction reduction, anti-wear, and service life extension are becoming more and more stringent. Lifetime lubrication is even more required on precision parts of electronic products such as some optical equipment and precision instruments. [0003] The traditional lubricating spray is to mix solid lubricating materials, binders, diluents and additives to make a coating, and mix it with propellant and put it into a spray can. This kind of lubricating spray is not suitable for the lubrication of micro-electromechanical systems because its lubricating active ingredients are solid, and the lubric...
