The preparation method is characterized in that a completely-synthesized cutting fluid, which is pollution-free to the environment and harmless for human bodies, and can satisfy the requirements on the processing technology of automobile wheel hubs, is synthesized through reactions, which are assisted by addition of other reasonable and compatible addictives, and carried out between novel special alcohol amine, organic carboxylic acid, and organic heterocyclic polybasic carboxylic acid.
Description
Technical field
The present invention relates to machining of metals liquid field, espespecially a kind of automotive hub fully synthetic cutting fluid and preparation method thereof.
Background technology
Cutting fluid is divided into water-insoluble (oil base) liquid and the large class of water-soluble (water base) liquid two by the oil product chemical constitution, and the former lubricity is good, but easily produces smog, has certain unsafe factor; And latter's cooling performance is good, but easy breed bacteria produces corruption, and rust-preventing characteristic is poor, and life cycle is short.Water base cutting fluid can be divided into again emulsion, semi-synthetic and fully synthetic cutting fluid.
Along with developing rapidly of industry, improving constantly of cutting technology, the continuous refinement of the division of labor, promoted the development of cutting fluid technology, reinforcement along with people's environmental protection consciousness, machining is also constantly to energy-conservation, the future development of environmental contamination reduction and reduction use cost, in the automotive hub course of processing, antirust and the rust prevention during manufacture slushing oil of traditional short-term, by aqueous rust preventive, substituted gradually, correspondingly, use the cutting fluid of oil-containing, need to clean and deoil automotive hub, and mostly the fully synthetic cutting fluid used at present is take that nitrite is as main rush-resisting material, generally also add some phenols salt and phosphoric acid salt, its main deficiency is contaminate environment, irritant to human body, even be detrimental to health, therefore automotive hub processing has proposed new requirement to the cutting fluid technology, it will promote the cutting fluid technology and develop to higher field.
Summary of the invention
A kind of automotive hub fully synthetic cutting fluid of the present invention and preparation method thereof, it is characterized in that, overcome the deficiency of prior art, taking full advantage of novel special hydramine reacts with organic carboxyl acid and organic heterocyclic polycarboxylic acid, and add other rational compatibleness additives, synthetic a kind of environmentally safe, non-stimulated to human body, and can meet the fully synthetic cutting fluid that the automotive hub complete processing requires.
Described novel special hydramine, be the mixture of one kind of multiple straight chain hydramine and cyclammonium, trade(brand)name SA103,
The red-brown transparent liquid, be less than other amine because the special base number of SA103 makes its corrodibility to aluminium,
Well below TEA, DEA, MEA, so SA103 especially is suitable for the processing of non-ferrous metal, little to the corrodibility of non-ferrous metal to the corrodibility of copper, SA103 can be used as pH value conditioning agent simultaneously, and the pH value stabilization is good.SA103 is used in metal working fluid has very strong rust-preventing characteristic and erosion resistance equally, with other amine commonly used, compares, and SA103 also has the cobalt metal dissolving lower than other amine, can extend cutting tool work-ing life;
