example 1

[0021] Put 600g of mineral oil into the kettle, add 80g of type A random polypropylene (molecular weight 25000), 150g of No. 50 petroleum wax paste, and 120g of petroleum residue oil, heat up and stir, when the temperature rises to 140-150°C, keep stirring for 20 ~ 30 minutes, stop heating, when the temperature drops to 125 ~ 130 ° C, add lanolin magnesium soap additive, stir evenly, and get out of the kettle. The composition and performance tests are shown in Table 1.

example 2

[0023] Put 510g of mineral oil into the kettle, add 110g of type A random polypropylene (molecular weight 35000), 250g of No. 45 petroleum wax paste, and 100g of petroleum residue oil, heat up and stir, when the temperature rises to 140-150°C, keep stirring for 20-20°C After 30 minutes, stop heating, add lanolin calcium soap additive when the temperature drops to 125-130°C, stir evenly, and leave the kettle. The composition and performance tests are shown in Table 1.

example 3

[0025] Put 500g of mineral oil into the kettle, add 120g of type A random polypropylene (molecular weight 28000), 200g of No. 50 petroleum wax paste, and 150g of petroleum residue oil, heat up and stir, when the temperature rises to 140-150°C, keep stirring for 20 ~ 30 minutes, stop heating, when the temperature drops to 125 ~ 130 ° C, add lanolin barium soap additive, stir evenly, and get out of the kettle. The composition and performance tests are shown in Table 1.

Abstract

The invention provides a kind of combination of alkyl consistent grease, which contains thickener, base oil and addition agent. by pivot of weight of all combination, every component follows this. 1, A type of atactic polypropylene which formula weight is 20000-40000 is 3%-18%. 2, petroleum wax is 10%-40%. 3, petroleum tar is 5%-30%. 4, lanolin metal soap antirust is 1%-7.5%. 5, mineral oil is alw. Because heavy polymer, A type of atactic polypropylene which can be dissolved in the oil, is used, the dripping spot of alkyl consistent grease risen above 80 degree and the problem that the intrinsic alkyl consistent grease has low dripping spot can be solved.

Description

technical field [0001] The present invention belongs to lubricating grease composition, in particular, it is a hydrocarbon base lubricating grease composition for metal rust prevention. technical background [0002] At present, hydrocarbon-based lubricating grease is mainly made of petroleum fat thickeners, namely ozokerite, paraffin and wax paste thickened with high-viscosity mineral oil and added with antirust agents. Such products have the problem of poor high temperature and cold resistance, which need to be improved. In the prior art, the basic formula of hydrocarbon-based lubricating grease is made by thickening high-viscosity mineral oil with ozokerite and wax paste, and adding anti-rust additives. This product has been used for many years and is still widely used now. Its advantage is that it is cheap and has good antirust performance; but its disadvantage is that the dropping point is relatively low, generally 58°C. Metal specimens and steel ropes using this produ...
