Machinery seal vapor phase anti-rust and preparation method thereof

Abstract

The invention relates to a machinery seal vapor phase anti-rust oil comprising following ingredients in percentage by weight: 3-15 percent of barium dinonynalphthalene sulfonate, 3-15 percent of petroleum sodium sulfonate, 1-15 percent of dodecencylsuccinic acid, 0-5 percent of dicyclohexyl amine nitrite, 0-5 percent of ethanol and 5-88 percent of hydrocarbon solvent. A preparation method of the machinery seal vapor phase anti-rust oil comprises the following steps of (1) putting the 5-88 percent of hydrocarbon solvent in a mixing cylinder and heating to 45 DEG C; (2) putting the 3-15 percent of barium dinonynalphthalene sulfonate, the 3-15 percent of petroleum sodium sulfonate and the 1-15 percent of dodecencylsuccinic acid into the mixing cylinder in sequence and stirring for 1h; and (3) evenly mixing the 0-5 percent of dicyclohexyl amine nitrite and the 0-5 percent of ethanol, putting in the mixing cylinder and stirring for 1h to obtain the product. The invention can effectively prevent corrosion of chloride and sulfide, has good high-wet resistance, no toxicity and good heat stability and can be mixed with lubricating oil, hydraulic oil or punching oil after being diluted.

Description

technical field [0001] The invention relates to a mechanically sealed vapor phase antirust oil and a preparation method thereof. Background technique [0002] Anti-rust oil is widely used in machinery. The existing closed lubricating oil or hydraulic oil system is protected. During transportation and shutdown, the lubricating oil of the parts is lost and exposed to the humid environment to produce rust. Existing sealing equipment, such as blind holes and dead corners of engines, large compressors, special gearboxes, etc., where there is no contact with anti-rust oil, are prone to oxidation and rust. Contents of the invention [0003] The present invention aims to solve the above problems, overcome the problems of easy oxidation and rust in blind holes and dead corners of sealing equipment where the anti-rust oil cannot be touched, and provides a mechanically sealed gas-phase anti-rust oil. The invention is applicable to the rust prevention of engines, large compressors an...
