Multifunctional barium-free anti-rusting oil and preparation process thereof

Abstract

The invention discloses multifunctional barium-free anti-rusting oil. The multifunctional barium-free anti-rusting oil comprises the following components in percentage by weight: 8%-10% of petroleum calcium sulfonate, 4%-6% of petroleum sodium sulfonate, 2%-5% of S-80, 0.1%-0.5% of T501 / 2, 6 di-tert-butyl p-cresol, 0.3%-0.5% of T706 benzotriazole, 10%-20% of 32# base oil, and 60%-70% of a refined petroleum solvent. The preparation process of the multifunctional barium-free anti-rusting oil comprises the following steps of: adding the refined base oil, the petroleum calcium sulfonate, the S-80 and the petroleum sodium sulfonate into a reaction kettle; heating to 90 DEG C-95 DEG C, cooling to 70 DEG C-80 DEG C after dissolving uniformly, adding the T706 benzotriazole and the T501 / 2, 6 di-tert-butyl p-cresol for uniformly dissolving, preserving the heat for stirring for over half an hour; and finally, filtering and filling into a barrel after diluting by using the refined petroleum solvent. Compared with the prior art, the multifunctional barium-free anti-rusting oil disclosed by the invention has the advantages that anti-rusting requirements of various metals can be satisfied at the same time, an oil film is thin, easy to clean, and the multifunctional barium-free anti-rusting oil is compatible with automobile lubricating oil, can be used for oil assembling, and is barium-free and environment-friendly.

Description

[0001] technical field [0002] The invention relates to a multifunctional barium-free antirust oil and a production process thereof, belonging to the technical field of chemical industry. Background technique [0003] At present, the use of anti-rust oil for temporary protection of metal parts between processes and before assembly is an ideal, economical and effective anti-rust method. In recent years, with the improvement of metal processing technology level and environmental protection awareness, higher requirements have been put forward for anti-rust oil products. Anti-rust oil is developing towards multi-functionality and ultra-thin layer, and the environmental protection requirements are strict. The appearance of metal parts exported to the United States and the European Union must be clean and rust-free to ensure that foreign companies can assemble them on the assembly line without cleaning the products, and foreign companies have clearly proposed to use barium-free ...

Problems solved by technology

However, most of the anti-rust oils it provides are developed by foreign laboratories and have not been optimized for the actual situation in China. Therefore, the requirements for the use environment and production process are very strict, the oil change cycle is short, and the use cost is high.

Especially in the rainy season from April to June and the high temperature and high humidity weather from July to September, the oil itself will corrode the metal parts after less than a week of use, the oil change cycle will be further shortened, and the chance of parts returning to rust very big
