Embodiment 1

[0037] Mix 80mL xylene, 50mL acetone, 0.157mol dimethyldichlorosilane, 0.043mol diphenyldichlorosilane and 0.1mol methylphenyldichlorosilane, keep warm at 30°C, mix 57.6ml water and 100ml acetone Add the mixed solution dropwise to the mixed solution and react at 30°C for 12 hours; after the reaction, wash the product with distilled water until neutral, then add 0.00375mol of hexamethyldisiloxane and 0.077g of tetramethylammonium hydroxide solution , reacted at 100°C for 10h, and washed the product with distilled water for 3-5 times after the reaction; put the washed product into a distillation device and heated it to 135°C, and removed the solvent under reduced pressure until no liquid distilled out. The liquid is polymethylphenylsiloxane.

[0038] Mix and heat 118.75g KN4010, 6.25g polymethylphenylsiloxane, 75.72g 12-hydroxystearic acid, and 30.77g benzoic acid to 95°C, keep stirring for 20min; heat up to 120°C, add 0.25mol isopropyl titanate Esters, heat preservation and st...

Embodiment 2

[0040] The preparation of polymethylphenylsiloxane was the same as in Example 1.

[0041] Mix and heat 112.5g KN4010, 12.5g polymethylphenylsiloxane, 75.72g 12-hydroxystearic acid, and 30.77g benzoic acid to 95°C, keep stirring for 20min; heat up to 120°C, add 0.25mol n-butyl titanate Esters, heat preservation and stirring, during which the by-product alcohols were blown out by nitrogen gas and condensed and collected. After 5 hours, 112.5g KN4010 and 12.5g polymethylphenylsiloxane were added to the system; the temperature was slowly raised to 220°C for high-temperature refining. After raising the temperature to the desired temperature, keep it for 3 minutes, then pour it into a stainless steel container, and after cooling down to room temperature naturally, add 4ml of water and repeatedly stir and shear, grind and homogenize to obtain the composite titanium-based grease.

Embodiment 3

[0043] The preparation of polymethylphenylsiloxane was the same as in Example 1.

[0044] Mix and heat 100g KN4010, 25g polymethylphenylsiloxane, 75.72g 12-hydroxystearic acid, and 30.77g benzoic acid to 95°C, keep stirring for 20min; heat up to 120°C, add 0.25mol isopropyl titanate, Insulate and stir, during which the by-product alcohols are blown out with nitrogen gas and condensed and collected. After 5 hours, 100g KN4010 and 25g polymethylphenylsiloxane are added to the system; the temperature is slowly raised to 220°C for high-temperature refining. Keep it at the required temperature for 3 minutes, then pour it into a stainless steel container, cool it down to room temperature naturally, add 4ml of water, stir and shear repeatedly, grind and homogenize to get the composite titanium-based grease.

Abstract

The invention relates to lubricating grease, in particular to a method for preparing compound Ti-based lubricating grease based on polymethylphenyl silicone. Mineral oil, polymethylphenyl silicone, 12-hydroxystearic acid and benzoic acid are mixed and heated to 95 DEG C, and heat insulation with stirring is performed to obtain a mixture 1. The mixture 1 is heated to 120 DEG C, titanate is added, heat insulation with stirring is performed, during the period by-products are blown out and condensed and collected, and the mineral oil and polymethylphenyl silicone are added into the system after 5 h to obtain a mixture 2. The mixture 2 is slowly heated to 220 DEG C to perform high-temperature refining; after the mixture 2 is heated to a required temperature, maintaining the temperature for 1-5 min, and then pouring the mixture 2 into a stainless container, performing natural cooling to room temperature and then adding water and repeatedly performing stirring and shearing, performing grinding and homogenization, and obtaining the compound Ti-based lubricating grease. The dropping point of the compound Ti-based lubricating grease prepared according to the method can reach 336 DEG C, steel mesh oil separation is less, the evaporation loss is small, a copper sheet is corroded up to standard, and the compound Ti-based lubricating grease has low friction coefficient.

Description

technical field [0001] The invention relates to lubricating grease, in particular to a preparation method of polymethylphenylsiloxane-based composite titanium-based lubricating grease. Background technique [0002] Lubricant plays an extremely important role in industrial production. It can reduce friction, thereby reducing unnecessary energy loss and protecting machinery to extend its service life. Composite titanium-based grease is a new type of grease with many excellent properties. It can replace traditional greases such as lithium-complex grease in many occasions, and the effect is remarkable. Compared with traditional lubricating grease, composite titanium-based lubricating grease without additives also exhibits excellent physical and chemical properties, so it has attracted the attention of researchers at home and abroad. [0003] The existing patent No. CN101307269A discloses a preparation method of composite titanium-based grease, the prepared composite titanium-ba...
