Embodiment 1
[0019] Synthetic example 1 of embodiment 1 additive
[0020] Weigh 5 grams of OP-10, dissolve it with 30 milliliters of acetone, add 10 milliliters of toluene, raise the temperature to 54-55 ° C, add ammonium persulfate (APS) initiator solution and 5 grams of sodium acrylate dropwise to the reaction system at the same time, drop After the addition is complete, keep the temperature for 5 hours, stop the reaction, remove the organic solvent by distillation, and obtain the self-made additive. The amount of APS accounts for 0.1% of the amount of sodium acrylate.
Embodiment 2
[0021] Synthetic example 2 of embodiment 2 additives
[0022] Weigh 10 grams of TWEEN-80, dissolve it with 30 milliliters of acetone, then add 10 milliliters of toluene, raise the temperature to 54-55 ° C, add APS initiator solution and 7 grams of ammonium acrylate dropwise, after the addition is complete, keep warm for about 5 hours, then stop Reaction, the organic solvent is removed by distillation, and the self-made additive is obtained. The amount of APS accounts for 0.2% of the amount of sodium acrylate.
Embodiment 3
[0023] Embodiment 3 Fully synthetic cutting fluid (I) preparation of the present invention
[0024] 15 grams of sodium oleate, 5 grams of OP-10, 15 grams of polyethylene glycol 400, 1.5 grams of borax, 12 grams of additives prepared as in Example 1, 0.2 grams of isothiazolinone, and 0.02 grams of emulsified silicone oil were dissolved in an appropriate amount of In deionized water, adjust the pH value of the above solution to about 9 with 10% sodium hydroxide aqueous solution to obtain a total amount of 100 grams of fully synthetic cutting fluid.
[0025] When using or performing performance tests, dilute fully synthetic cutting fluid I 20 times with deionized water or distilled water before use.

Abstract
The invention discloses a fully synthetic cutting fluid which comprises anion active agent, non-ionic surface active agent, polyethylene glycol, borax, bactericide, foam suppressor, pH regulator, water and additive; wherein, the additive is prepared by the following method: the surface active agents are dissolved by acetone, the mixed solution is added with toluene and heated up to 50-60 DEG C, and the reaction system is dripped with acrylate monomer as well as azodiisobutyronitrile (AIBN) or ammonium persulfate (APS) evocating agent; after that, the temperature is preserved for 3-5h, the reaction stops, and organic solvent is removed, so that the additive is obtained. Compared with the existing fully synthetic cutting fluid, the fully synthetic cutting fluid of the invention can completely inhibit leaching of cobalt element in hard alloy containing cobalt when metal is processed, well solves the problem of separating the cobalt in the existing fully synthetic cutting fluid, and is environment-friendly and efficient.
Description
technical field [0001] The invention relates to a fully synthetic cutting fluid for metal processing, in particular to a fully synthetic cutting fluid capable of inhibiting cobalt precipitation. Background technique [0002] Water-based metal cutting fluid can be divided into three types: soluble oil (emulsion), semi-synthetic cutting fluid (microemulsion) and fully synthetic cutting fluid. Compared with soluble oil and semi-synthetic cutting fluid, fully synthetic cutting fluid does not contain mineral oil, and its various components such as anti-rust agent, extreme pressure anti-wear additive, surfactant, preservative and defoamer and other additives are Soluble in water, the diluent is transparent or translucent. Fully synthetic cutting fluid has the following main advantages: (1) Excellent cooling and cleaning performance, so it is suitable for high-speed cutting; (2) The solution is transparent and has good visibility, especially suitable for modern processing equipmen...
