Long carbon chain dicarboxylic acid total synthesis cutting fluid and preparation method thereof

Abstract

The invention relates to a metal processing cutting fluid and specifically relates to a long carbon chain dicarboxylic acid total synthesis cutting fluid and a preparation method thereof. Long carbon chain dicarboxylic acid, borate and triazole are selected to be coordinated with an antirusting agent for using, and water, lubricating agents, organic amine, boric acid, the long carbon chain dicarboxylic acid, antiseptics, the triazole, softening agents and defoaming agents are used as main ingredients so that defects of poor antirust performances and large additive amounts, which are caused by independently using the borate, benzoate, sebacic acid and urotropine, are overcome. The cutting fluid is stable, good in the antirust performances, excellent in performances of lubrication, rust protection and corrosion prevention and capable of meeting requirements of short-term rust protection among processes; simultaneously, problems of caking of sodium nitrite on metal surfaces during the using of the sodium nitrite are solved, and the long carbon chain dicarboxylic acid is biodegradable and is a green and environment-friendly antirusting agent; and the long carbon chain dicarboxylic acid total synthesis cutting fluid is biodegradable, green and environment-friendly and suitable for various mechanical processing and particularly for various grinding machine processing technologies.

Description

technical field [0001] The invention relates to a cutting fluid for metal processing, in particular to a fully-synthesized cutting fluid with a long carbon chain dibasic acid and a preparation method thereof. Background technique [0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, chipping and grinding. Good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute. At present, the antirust agents used in fully synthetic cutting fluids are usually selected such as borates, benzoates, sebacic acid, urotropine, etc. Although these types of antiseptics are cheap, they have general antirust performance. The quantity is large, and the overall cost performance is not high; sodium nitrite is poisonous, and when added to the cutting fluid, it will crystallize and precipitate after a period of time, easily adsorbed on the metal...

Problems solved by technology

At present, the antirust agents used in fully synthetic cutting fluids are usually selected such as borates, benzoates, sebacic acid, urotropine, etc. Although these types of antiseptics are cheap, they have general antirust performance. The quantity is large, and the comprehensive cost performance is not high; sodium nitrite is poisonous, when added to the cutting fluid, it will crystallize and precipitate after a period of time, it is easy to adsorb on the metal surface, forming agglomerates, and it is difficult to clean. The country has restricted or banned the use of such products
