Abstract

The invention relates to a preparation method of a weather-resistant antirust oil for electromechanical equipment, and belongs to the technical field of antirust oil preparation. The method comprises the following steps: mixing ethyl orthosilicate, n-butyl alcohol and deionized water, heating the mixture, dropwise adding ammonia water, reacting, adding washed flax fibers to continuously react, carrying out suction filtration and drying to obtain a dried product, and then mixing the dried product with methyl benzene and octadecyl trichlorosilane, stirring the mixture to react, so as to obtain a super-oil-absorbing fiber, and finally stirring the super-oil-absorbing fiber with is CV-A100 vacuum pump oil, liquid paraffin and other substances, and dispersing the mixture to obtain the weather-resistant rust-proof oil for electromechanical equipment. The prepared weather-resistant antirust oil is good in weather resistance, the flash point reaches more than 235 DEG C, the paint film is stable and not easy to fall off; and the viscosity reaches 15-17 mm<2>.s<-1> at 40 DEG C and the viscosity coefficient is high.

Description

technical field [0001] The invention relates to a method for preparing weather-resistant antirust oil for electromechanical equipment, and belongs to the technical field of antirust oil preparation. Background technique [0002] Antirust oil is usually made by mixing solvents, antirust agents and other auxiliary additives (such as dispersants, antioxidants, antifungal agents and defoamers, etc.). The solvent can act as a carrier in the anti-rust oil to disperse the anti-rust agent in the oil; it can also play the role of oil effect. Antirust agent, also known as oil-soluble antirust agent, is a key component in antirust oil that plays an antirust role. The role of auxiliary additives is to improve a certain performance of anti-rust oil or coating film. Anti-rust oil is mostly used for temporary anti-rust during the process, transportation or storage of metal products (mainly steel products). [0003] It has the advantages of good effect, convenient use, low cost, easy con...
