Embodiment 1

[0017] An anti-rust oil for refrigeration equipment, characterized in that it is composed of the following parts by weight (kg) of raw materials:

[0018] N32#machine oil 80, alkenyl succinate 10, ethylene glycol butyl ether 2, oleic acid triethanolamine 0.8, rosin acid polyoxyethylene ester 5, 1-hydroxybenzotriazole 1, lanolin magnesium soap 3 Disodium lauroyl glutamate 0.2, dimethyl silicone oil 0.3, dibutyl tin dilaurate 0.4, film forming aid 5;

[0019] The said film-forming aid is composed of the following raw materials in parts by weight:

[0020] Coumarone resin 50, methyl methacrylate 10, aluminum isopropoxide 1, trimethylolpropane triacrylate 5, Span-80 0.5, dewaxed kerosene 26, palmitic acid 1;

[0021] Heat the above coumarone resin at 75-80°C, add methyl methacrylate, stir to room temperature, add dewaxed kerosene, and stir and mix at 60-80°C for 30-40 minutes;

[0022] Mix aluminum isopropoxide and palmitic acid, ball mill uniformly, add trimethylolpropane triacrylate, sti...

Abstract

The invention discloses a rust preventive oil for refrigeration apparatuses. The rust preventive oil comprises, by weight, 71-80 parts of N32# machine oil, 5-10 parts of alkenyl succinate, 1-2 parts of ethylene glycol monobutyl ether, 0.8-2 parts of triethanolamine oleate, 3-5 parts of polyoxyethylene abietate, 1-2 parts of 1-hydroxybenzotriazol, 0.2-0.4 parts of disodium lauroyl glutamate, 3-5 parts of lanois magnesium soap, 0.3-1 part of dimethicone, 0.4-1 part of dibutyltin dilaurate and 5-7 parts of a film forming assistant. The rust preventive oil has the advantages of reasonable compounding of raw materials, high reduction of the surface tension, increase of the compatibility of all components, and good low temperature fluidity, and is especially suitable for the refrigeration apparatuses.

Description

Technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to an anti-rust oil for refrigeration equipment. Background technique [0002] Anti-rust oil is made by adding lubricating oil as base oil and adding anti-rust agent and some improved additives. Generally, anti-rust oil can be divided into replacement type anti-rust oil, lubricating oil type anti-rust oil, solvent dilution type anti-rust oil and so on. Among them, lubricating oil-type anti-rust oil is the main rust-preventing oil in my country. It has a wide range of applications. It is mainly used for internal anti-rust of machinery, and can be used for anti-rust sealing and lubrication immediately after unsealing. In addition, this product can also be applied to the rust prevention and lubrication of the frictional working surface of various machinery. Especially, it is widely used in the friction parts of port machinery and marine machinery, such as steel wire ropes. Tod...
