Abstract
An environmental protective grinding fluid consists of water soluble polymer surfactant 2-10wt%, composite organic boric acid ester 1-12wt%, additive lubricant cleaning agent 2-20wt%, anti-rusting agent 0.3-3wt%, antibacterial agent 0.1-1wt%, complexing agent 0.1-0.5wt% and water. The organic boric acid ester is prepared by synthesizing borate 20-40%, diglycol 10-30% and glycol ethamine 10-25% with oleic acid 10-25%, binary carboxylic anhydride 5-10% and thiurea 1-3%. It has no harmful substances, better comprehensive performance and chemical stability.
Description
The present invention relates to a kind of metal processing and use chemical assistant, is the preparation method who belongs to the environment-friendly type grinding fluid.
The metal manufacture field is extensive use of grinding fluid, and it mainly plays cooling, lubricated, antirust, cleanup action.This grinding process since the midium or long term always all at the oil-in-water type grinding fluid that uses emulsification ointment, yellow soda ash, Sodium Nitrite preparation.Along with the high speed development of mechanical industry, use the novel precise grinding machine of automatization in a large number, particularly under the requirement of improving the quality of products, use this grinding fluid can not satisfy the needs that improve the quality of products.At first, this grinding fluid life-span is short, rots easily, makes product produce corrosion easily; Secondly, harmful owing to containing nitrite; Once more, this grinding fluid is prepared based on mineral oil, and the oleaginousness height does not meet the emission standard of environmental protection.Some synthetic grinding fluids have appearred in recent years, it is a kind of novel water-based grinding fluid, it is formulated by various water-soluble additive, has stable performance, life cycle is long, low cost and other advantages, but most rust-preventing characteristic, oilness can not meet the demands is as problem such as occur long blackspot easily in lathe cast iron precision work process, get rusty; What have also adds carcinogenic substances such as nitrite in grinding fluid, what have also contains objectionable impuritiess such as phosphorus, chlorine, heavy metal.
The purpose of this invention is to provide a kind of not containing, and have oilness, cooling property, rust-preventing characteristic, cleaning and the good environment-friendly highly efficient grinding fluid of chemical stability human body, the deleterious material of environmental protection.
The grinding fluid of the environment-friendly type of wood invention, comprise that water-soluble polymer tensio-active agent 2-10% and compound organic boric acid ester 1～12% with weight percent are main raw material, auxiliary agents preparations such as the lubricated clean-out system of interpolation, rust-preventive agent, antiseptic-germicide, complexing agent add water and form, the weight proportion that adds auxiliary agent is respectively 2～20%, 0.3～3%, 0.1～1%, 0.1～0.5%, and all the other are water.
The preparation of this environment-friendly type grinding fluid is raw materials used to be preferred low-molecular-weight polyacrylic acid salt; low molecular weight polyacrylamide; polyoxyethylene glycol; polyvinyl alcohol; the lower molecular weight polyoxyethylene; water-soluble polymer tensio-active agents such as polyethers; amine hydroxybenzene; the castor-oil plant acid amides; the tallow alkyl Propanolamine; glycerine; thanomins etc. are as lubricated clean-out system; compound organic boric acid ester; N; the N-dimethylethanolamine; N-acyl group leucine salt; the N-acyl glutamate is an extreme-pressure anti-wear; antirust; antiseptic-germicide; molybdate; benzotriazole is a rust-preventive agent; boric acid is antiseptic-germicide, disodium ethylene diamine tetraacetate; tetrasodium ethylenediamine tetraacetate is complexing agent and defoamer or the like.Described organic boric acid ester is preferably formed by the reaction of compounds such as the borate 20～40% of weight percent, glycol ether 10～30%, diethanolamine 10～25%, oleic acid 10～25%, dicarboxylic acid anhydride 5～10%, thiocarbamide 1～3%.The stable of chemical property more can be brought into play and guarantee to the cooperation of organic boric acid ester of Xing Chenging and polymeric surface active agent like this.
Characteristics of the present invention are: (one) is owing to the compound organic boric acid ester with good combination property is a main raw material, add the polymeric surface active agent of optimum quantity in addition, further protected the chemical stability of boric acid ester, can improve the over-all properties of grinding fluid, main is that the chemical stability of compound organic boric acid ester is further protected, bring into play its over-all properties more, and prescription rationally; (2) owing to do not contain materials such as deleterious mineral oil, nitrite, heavy metal, phenol, formaldehyde, phosphorus, chlorine, harmless, the friendly product of based environment, and also pH value is controlled at 8.5～9.0, can not injure user's skin; (3) owing to do not contain the easily mouldy material of mineral wet goods, and added antiseptic-germicide, so life cycle was generally more than 4 months, defoaming is qualified, rust-preventing characteristic: monolithic＞150h, lamination＞72h; (4) because product of the present invention is colourless or light yellow transparent liquid, working fluid is Clear ﹠ Transparent, helps observing finished surface, can improve workpiece smooth finish, and oilness is good, the work-ing life that can improve emery wheel.
The GB6144-85 standard detection is pressed in rust-preventing characteristic check among the present invention.
