High temperature resistant antioxidant long-acting antirust grease and preparation method thereof

Abstract

The invention discloses a high temperature resistant antioxidant long-acting antirust grease. The high temperature resistant antioxidant long-acting antirust grease is characterized in that the antirust grease is prepared from the following raw materials in parts by weight: 12-14 parts of high viscosity mineral oil, 15-28 parts of coal oil, 5-7 parts of 200-mesh amorphous graphite, 3-5 parts of nano zinc oxide, 1-2 parts of OP-8 emulsifier, 2-3 parts of aluminum distearate, 43-47 parts of solid paraffin, 12-15 parts of Vaseline, 1-2 parts of calcium hydroxide, 1-2 parts of zinc butyl octyl dithiophosphate, 6-8 parts of barium dinonyl naphthalene sulfonate and 2.5-4 parts of protective agent. The high temperature resistant components such as amorphous graphite and nano zinc oxide are added into the antirust grease through grinding, so that the high temperature resistance and heat stability are enhanced; the protective agent is added, so that the antirust grease has good waterproof lubrication effect, a firm hydrophobic membrane can be formed on the surface of metal, and rusting caused by corrosion of water and oxygen is avoided; the antirust grease is resistant to high temperature and oxidation, the product is not evaporated all the year round, the effect is lasting, and the antirust performance is excellent.

Description

technical field [0001] The invention relates to the field of anti-rust liquid, in particular to a high-temperature-resistant and anti-oxidation long-acting anti-rust grease and a preparation method thereof. Background technique [0002] In order to protect the metal from the corrosion of the corrosive medium in the environment, anti-rust grease is usually used in engineering construction to isolate the metal surface from the corrosive medium. Using anti-rust grease as a temporary protection is an ideal and effective anti-corrosion method, which has the advantages of good effect, convenient use, low cost, easy operation and easy removal. However, most anti-rust greases need to be heat-sealed, the operation is complicated, and the thermal stability and anti-oxidation stability are difficult to meet the requirements. This requires the anti-rust grease to have good thermal stability and high temperature resistance. [0003] Through research and development, the use of special t...
