Abstract
The invention relates to an environment-friendly water-based metal working fluid and a preparation method thereof. The water-based metal working fluid comprises the following ingredients in parts by weight: 15-20 parts of fatty alcohol-polyoxyethylene ether, 15-20 parts of coconut oil fatty acid diethanolamide, 15-20 parts of coconut oil amine polyoxyethylene ether, 3-6 parts of a rosin alcohol solution, 2-5 parts of a synthetic antirusting agent, 0.1-0.2 part of a defoaming agent, 0.3-0.5 part of benzotriazole and the balance of water. The water-based metal working fluid is good in lubricity, high in anti-rust property, high in antibacterial ability, high in stability, and long in service life, does not pollute the environment, is harmless to the human body, and comprehensively satisfies the requirements of highly difficult machining for cutting.
Description
technical field
The present invention relates to a kind of environment-friendly type water metalworking fluid and preparation method thereof, belong to metal processing sectors.
technical background
Current domestic traditional intermetallic composite coating enterprise great majority use Sodium Nitrite and oil in water emulsion to allocate making metal working fluid voluntarily for main raw material, some enterprises are also had to use common finish and emulsifying agent to be made as metal working fluid, there is contaminate environment in above-mentioned metal working fluid, perishable smelly, harmful to the person, lathe, cutter and work material, harm worker is healthy, also there is working fluid corrosion processing material, knife sharpener consumption is large, the shortcomings such as unstable product quality.
Modern mechanical processing also makes machining difficulty day by day increase to the development of the difficult-to-machine material such as high speed, brute force, accurate future development, superhard, super-strength.The reason of these two aspects causes the frictional force in cutting process, heat of friction increases substantially, and this just requires that metal working fluid has better lubrication, cooling, cleaning, rustless property, to obtain desirable finished surface.The lubrication of mineral lubricating oils, rustless property is superior, but cooling, cleaning performance is poor; Cooling, the cleaning performance of emulsion are excellent, but lubrication, rustless property are poor.
Summary of the invention
The object of this invention is to provide and a kind ofly improve grinding speed, grinding temperature is cut in reduction, biodegradable, environmental pollution is little, cost is low metal working fluid.
For realizing above object, a kind of environment-friendly type water metalworking fluid of the present invention, its component and weight proportion are: fatty alcohol-polyoxyethylene ether 15-20 part; Cocoanut fatty acid diethanolamide 15-20 part; Coco amine Soxylat A 25-7 15-20 part; Rosin spirituous solution 3-6 part; Synthesis rust-preventive agent 2-5 part; Defoamer 0.1-0.2 part; Benzotriazole 0.3-0.5 part; The water of surplus.
Further, described synthesis rust-preventive agent comprises Sodium hexametaphosphate 99, triethanolamine oleate ester and water.
Further, in described synthesis rust-preventive agent, the mass ratio of Sodium hexametaphosphate 99, triethanolamine oleate ester and water is 1-2:4-5:10.
A preparation method for environment-friendly type water metalworking fluid, comprises the steps:
Fatty alcohol-polyoxyethylene ether, cocoanut fatty acid diethanolamide, coco amine Soxylat A 25-7, rosin spirituous solution, synthesis rust-preventive agent, defoamer, benzotriazole and water are mixed in proportion, and stir, through after the assay was approved, obtained environment-friendly type water metalworking fluid.
The beneficial effect that the present invention produces is:
(1) cooling performance is given prominence to: greatly can take away heat in metal cutting and fully cool cutter, it is made to keep hardness, intensity, working fluid in use can infiltrate in the superfine microfracture of workpiece cutting surface, make surface metal lattice brittle, machining is easily carried out, thus improves working efficiency.
(2) oilness superior performance: form oil-bound film in cutting zone, the last non seizure load PB value of cutting fluid can reach more than 716N, reduce frictional coefficient, reduce heat generation, reduce cutting force, reduce the consumption of cutter and emery wheel, significant prolongation cutter life, surface processing accuracy significantly improves, and solves lubrication and antirust contradiction between the two well.
(3) excellent stability: the physical and chemical stability that complete synthesis structural rigidity regulates automatically and anti-waste oil ability ensures under high pressure, under correct maintenance, can life-time service.When storing and use, not stratified, can not throw out be separated out, not easily corrupt, do not produce the gas hindering workers ' health.Simultaneously also not containing carcinogenic substances such as nitrite, Working environment is totally tasteless, and adding man-hour can clear observation workpiece surface.Work waste liquid is few, greatly reduces environmental pollution.
