High-efficiency antirust grease and preparation method thereof

Abstract

The invention discloses high-efficiency antirust grease and a preparation method thereof. The grease comprises the raw materials of, by weight: 20-40 parts of base oil A, 40-60 parts of base oil B, 4-6 parts of octadecylamine, 3-4 parts of diphenylmethane diisocyanate, 0.5-2 parts of hexamethylenediamine, 1-3 parts of an antioxidant , 2-4 parts of an antirust agent A, and 3-5 parts of an antirust agent B. The preparation method is that: the raw materials are added according to a certain ratio under an appropriate temperature, and mixing and blending is carried out. The antirust grease provided by the invention has excellent high-temperature resistance, high-humidity resistance, salt-spray resistance, and atmospheric corrosion resistance. The grease has good antirust effect for black and non-ferrous metals. The grease is mainly used in long-term storage and antirust of metal products such as bearings, machine tools, machine tool accessories, auto parts, hardware tools, machinery, ordnance, and the like.

Description

technical field [0001] The invention relates to the field of lubricating grease, in particular to a high-efficiency antirust grease and a preparation method thereof. Background technique [0002] At present, there are dozens of varieties of anti-rust grease in China. This kind of anti-rust grease is mainly made of paraffin wax or fatty acid soap thickener, combined with sulfonate and other non-ferrous metal corrosion inhibitors. It is usually used for packaging of various mechanical parts, Storage, high and low temperature performance are poor, anti-rust grease with paraffin as thickener needs to be heated when oil seal and unseal, the operation is complicated and the thermal stability and anti-oxidation stability are difficult to meet the requirements, and it contains metal ions High-quality anti-rust grease will accelerate surface oxidation, and the anti-rust period is shorter in harsh environments. At present, domestic anti-rust grease mainly has problems such as poor an...

Problems solved by technology

[0002] At present, there are dozens of varieties of anti-rust grease in China. This kind of anti-rust grease is mainly made of paraffin wax or fatty acid soap thickener, combined with sulfonate and other non-ferrous metal corrosion inhibitors. It is usually used for packaging of various mechanical parts, Storage, high and low temperature performance are poor, anti-rust grease with paraffin as thickener needs to be heated when oil seal and unseal, the operation is complicated and the thermal stability and anti-oxidation stability are difficult to meet the requirements, and it contains metal ions The anti-rust grease will accelerate the surface oxidation, and the anti-rust period is shorter in harsh environments

At present, the domestic anti-rust grease mainly has the problems of poor anti-rust effect and short service life. Generally, the salt spray test of grease will cause serious corrosion within three to seven days.
