Description
Technical field
The present invention relates to cutting fluid technical field, be specifically related to a kind of water-soluble anti-rust cutting fluid and preparation method thereof.
Background technology
Metal cutting is a kind of application working method widely, and can produce very large friction and heat between cutter and workpiece in working angles, this not only affects the quality of working (machining) efficiency and workpiece, also can cause damage to cutter and equipment.Therefore having the cutting fluid of good lubrication, cooling, cleaning and rustless property, is the target always pursued in metal cutting process.
Cutting fluid is that one is used in metal and cuts, cuts, grinds in the course of processing, be used for the industrial type fluid of Cooling and Lubricator cutter and workpiece, cutting fluid is formed through science compound compatibility by multiple super strong functional auxiliary agent, possesses good cooling performance, lubricity, rustless property, oil removing cleaning function, anti-corrosion function, easily dilutable feature simultaneously.Overcome the easily difficult dilution in smelly, winter in summer of traditional soap base emulsion, rust-proof effect difference defect, lathe paint is also had no adverse effects.
The performance of cutting fluid depends on its moiety, and cutting fluid is of a great variety, forms multifarious, usually cutting fluid is divided into water-insoluble (oil base) liquid and the large class of water-soluble (water base) liquid two.The lubricity of oil base cutting fluid is better, and cooling performance is poor.Water-base cutting fluid lubricity compared with oil base cutting fluid is relatively poor, and cooling performance is better.Cut at a slow speed and require that the oilness of cutting fluid is eager to excel, in general, cutting speed uses machining oil lower than during 30m/min.
But due to oil base cutting fluid cost high and pollute relatively serious, thus the water-base cutting fluid product of environmental type performance is had to be the developing direction of cutting fluid, the abundance of water, and it is nonpoisonous and tasteless, be desirable green basal liquid, make great efforts to improve water-base cutting fluid performance and will obtain larger share of market.
At present, the water-soluble metalworking liquid used both at home and abroad is mainly divided into emulsified cutting fluid and water based synthetic cutting fluid.The former, primarily of water, mineral oil and emulsifying agent composition, is characterized in that lubricity is good, but poor in cooling, perviousness, stability, and life cycle is short, there is environmental issue during discharge, not biodegradable, easily produces the phenomenons such as mouldy, smelly; The latter forms primarily of various water-soluble additive (as lubrication, wear-resistant, resistance to compression, antirust, tensio-active agent etc.) and water, be characterized in not oil-containing, performance has good cooling, cleaning, stability, having positive meaning from aspects such as environmental protection, saving oil resources, is the main flow of cutting fluid development.
CN100485018C discloses and a kind ofly belongs to the chemosynthesis auxiliary agent used in metal cutting process technical field, has the water-base cutting fluid of cooling, antirust, cleaning and lubricating function.This invention, by rust-preventive agent, tensio-active agent, lubricant and other auxiliary chemicals, mixes under certain condition and namely obtains desired product.The wherein composition of this cutting fluid and content (by weight percentage) thereof: to tert-butylbenzene formic acid 1 ~ 3%, phenylformic acid 2 ~ 5%, boric acid 2 ~ 4%, ethanolamines 2 ~ 8%, the polyoxyethylene glycol 4 ~ 8% of molecular weight 400 ~ 600, benzotriazole 0.1 ~ 0.5%, the polyacrylamide 0.05 ~ 0.2% of non-ionic type, excess water.This cutting fluid has excellent abrasive dust settleability, and not scab is taken turns; Excellent antirust, cooling, cleaning and lubricity; Never degenerate smelly; Long service life.Feature of the present invention is the compound not containing nitrite and phosphorus, to environment and healthy and beneficial.
But in prior art, water-soluble metalworking liquid still needs to be improved further in work-ing life, rust-preventing characteristic, oilness, adaptation unlike material etc., to substitute oil base cutting fluid better.
