Embodiment 1

[0043] An additive package (Type A) for producing microemulsified cutting fluid, the weight ratio of which is composed of: 19 parts of higher fatty acid, 28 parts of alcohol amine, 11 parts of sodium petroleum sulfonate, 7 parts of sorbitan monooleate, 5 parts of fatty alcohol polyoxyethylene ether, 10 parts of coconut oil diethanolamide, 10 parts of butyl carbitol, 4 parts of polyether, 0.2 part of benzotriazole, 2 parts of antiseptic and fungicide, 3.8 parts of water. Vegetable oleic acid or tall oleic acid or a half-and-half mixture is used for higher fatty acids; monoethanolamine and triethanolamine are used for alcohol amines, and the weight percentage of the two is: monoethanolamine 40%, triethanolamine 60%.

[0044] The obtained additive package is a uniform and transparent liquid, which does not become turbid or stratified after standing at 70°C for 4 hours, and freezes at -12°C for 4 hours and returns to room temperature without crystallization or precipitation, and ca...

Embodiment 2

[0048] An additive package (Type A) for producing microemulsified cutting fluid, the weight ratio of which is composed of: 15 parts of higher fatty acid, 25 parts of alcohol amine, 10 parts of sodium petroleum sulfonate, 11 parts of sorbitan monooleate, 8 parts of fatty alcohol polyoxyethylene ether, 8 parts of coconut oil diethanolamide, 8 parts of butyl carbitol, 3 parts of polyether, 0.4 part of benzotriazole, 3 parts of antiseptic and bactericide, and 8.6 parts of water. Vegetable oleic acid or tall oleic acid or a half-and-half mixture is used for higher fatty acids; monoethanolamine and triethanolamine are used for alcohol amines, and the weight percentage of the two is: monoethanolamine 40%, triethanolamine 60%.

[0049] The obtained additive package is a uniform and transparent liquid, which does not become turbid or stratified after standing at 70°C for 4 hours, and freezes at -12°C for 4 hours and returns to room temperature without crystallization or precipitation, a...

Embodiment 3

[0053] A (Type B) additive package for producing microemulsified cutting fluid, the weight ratio of which is composed of: 19 parts of higher fatty acid, 28 parts of alcohol amine, 11 parts of sodium petroleum sulfonate, 7 parts of sorbitan monooleate, 5 parts of fatty alcohol polyoxyethylene ether, 10 parts of coconut oil diethanolamide, 10 parts of butyl carbitol, 4 parts of polyether, 0.2 part of benzotriazole, 2 parts of antiseptic and fungicide, 3.8 parts of water. Higher fatty acid uses ricinoleic acid or coconut oleic acid or the mixture of both; Alcohol amine uses monoethanolamine and triethanolamine, the weight percentage of both is: monoethanolamine 40%, triethanolamine 60%.

Abstract

The invention relates to a micro-emulsified cutting fluid production additive package and a preparation method and the application thereof. The additive package is composed of, by weight, 5-25 parts of higher fatty acid, 10-35 parts of alkylol amine, 3-15 parts of sodium alkane sulfonate, 5-20 parts of sorbitan monooleate, 2-15 parts of fatty alcohol-polyoxyethylene ether, 3-15 parts of coconutt diethanol amide, 3-15 parts of butyl carbitol, 1-5 parts of polyether, 0.1-0.6 part of benzotriazole, 1-5 parts of antiseptic bactericide and 3-10 parts of water. The additive package is high in emulsifying ability, high in emulsifying efficiency, and fine in hard water resistance and bubble inhibition performance in preparation of cutting fluid, and micro-emulsified cutting fluid is high in water solubility and free of coagulation, caking and precipitation.

Description

technical field [0001] The present invention relates to an additive composition for producing microemulsion cutting fluid (hereinafter referred to as additive package, Additive package) and its preparation method and application. Background technique [0002] Microemulsion cutting fluid is mainly used in metal processing as a process medium. In the national standard GB / T 7631.5-1989 "Classification of Lubricants and Related Products (Class L) Part 5: Group M (Metal Processing)", the two symbols MAE and MAF correspond to microemulsion cutting fluids. The description of the product type and (or) end-use requirements in this standard is: MAE is a concentrate mixed with water, which has antirust translucent emulsion (microemulsion), and MAF has antifriction and (or) extremely Compressive MAE type concentrate; general application is metal processing; special purpose is for metal removal processes such as cutting, abrasive processing, for stamping, deep drawing, calendering, powe...
