Environment-friendly type near dry cutting liquid and preparation method thereof
Technical field
The present invention relates near dry cutting liquid technical field, specifically a kind of environment-friendly type near dry cutting liquid and preparation method thereof.
Background technology
Lubricated and the refrigerant that traditional metal processing is used is generally pure oil or emulsion, and the usage quantity of lubricated cooling (oil) liquid is big, not only wastes the bulk petroleum resource, also can cause the huge pollution of processing site and environment, also makes the operator ill simultaneously easily.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of environment-friendly type near dry cutting liquid that adopts new formulation to form.
For achieving the above object, designed a kind of environment-friendly type near dry cutting liquid, it is characterized in that being prepared from by following raw materials by weight percent:
Dialkyl group thiophosphate 20-40%
Carbaminate 20-40%
Polyalkylene glycol 20-40%
Carboxylic acid amine 2-5%
Sodium Benzoate 1-2%
Glycolylurea 1-2%
Deionized water 15-35%.
A kind of preparation method of environment-friendly type near dry cutting liquid is characterized in that preparing as follows: (1) takes by weighing raw material by the described weight percent of claim 1; (2) dialkyl group thiophosphate, carbaminate, polyalkylene glycol, carboxylic acid amine, Sodium Benzoate, the glycolylurea that is taken by weighing mixed after, stir; (3) add deionized water again; (4) restir is after 30 minutes, promptly pack finished product.
Described dialkyl group thiophosphate is the mixture of any or both in dialkyl group thiophosphoric acid zinc, the dialkyl group thiophosphoric acid ammonium.
Described carbaminate is the mixture of any one or both in dialkyl thiocarbamic acid zinc, the dialkyl thiocarbamic acid antimony.
The present invention compares with prior art, have good oilness and extreme pressure anti-wear, very a spot of cutting fluid just can satisfy the high-end requirement of metal working process, cooperates the near dry cutting device to use, it is original below 10% that the usage quantity of lubricant is dropped to, and reduces the harm to environment and workman; Wherein, thereby dialkyl group thiophosphate, carbaminate energy and metal react and make the harder mechanical wear that prevents in metallic surface, and simultaneously, friction has been reduced in more slick metallic surface, also help reducing surface load, the compound use of two series products has mutual synergic effect in this prescription; Polyalkylene glycol is used for improving the sticking power of working liquid to the metallic surface, plays good lubrication in this prescription; Carboxylic acid amine can be powerful attached to the metallic surface, forms the barrier film of draining, effectively prevents metallic corrosion; Sodium Benzoate, glycolylurea prevent the breeding of bacterium and mould mainly as sterilant; Deionized water mainly plays cooling effect, strengthens the mutual solubility of each component simultaneously.
