Abstract

The invention discloses bearing anti-rust oil and a preparation method thereof. The preparation method includes the following steps of firstly, taking heavy calcium carbonate powder to be ground through a grinding machine; secondly, increasing the temperature in a stirring tank to be 90-120 DEG C, and adding 140-170 parts of mineral oil, 3-7 parts of petroleum sodium sulfonate, 2-4 parts of phytic acid, 3-6 parts of nonylphenol polyoxyethylene ether, 2-5 parts of calcium lignosulphonate and 1-5 parts of hydroxyl-terminated polybutadiene into the stirring tank to be stirred for 30-50 min; thirdly, adding 4-8 parts of starch sodium octenylsuccinate, 0.5-1 part of fluorocarbon resin, 1-4 parts of acetyl castor butyl alcohol acid, 1-3 parts of perfluorinated octyl ethyl acrylate and 1-3 parts of heavy calcium carbonate powder into the stirring tank to be stirred for 20-40 min, and cooling to prepare the bearing anti-rust oil. The prepared bearing anti-rust oil can effectively prevent bearings from rusting.

Description

technical field [0001] The invention belongs to the field of antirust oil, and relates to a bearing antirust oil and a preparation method thereof. Background technique [0002] In order to avoid corrosion and reduce losses, people have adopted various methods, and using anti-rust grease to protect metal fasteners is one of the most common protection methods at present. During the storage, transportation and use of metals, due to the influence of water vapor, oxygen, acid, alkali, salt and carbide in the ambient atmosphere, physical and chemical changes will occur under certain temperature, humidity and time extension conditions. rust due to change. The corrosion of metal will cause the loss of metal and the decline and loss of the function of metal parts. Metal rust is caused by the oxidation reaction of metal in contact with moist air or electrolyte solution. Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechani...
