Problems solved by technology

Kerosene has high dielectric strength, low viscosity and good fluidity. It is a commonly used working fluid in EDM. However, kerosene has a low flash point, high volatility, strong odor, and poor safety, which can easily cause fire accidents.
Special mineral oil can overcome some shortcomings of kerosene, but this type of oil contains a certain amount of aromatic hydrocarbons, which leads to poor safety of oil products, odor, and irritating effect on the

Example Embodiment

[0008] The first step is to add sorbitol anhydride monooleate to the engine oil according to the mass ratio of 1: (3~5), and heat and stir to dissolve it in the engine oil to form a mixture of engine oil; the second step is for sorbitan monooleate The mass ratio of ester, alkylphenol polyoxyethylene ether, rosin and engine oil is 1:(0.05~0.15):(0.10~0.15):(3~5). Add alkylphenol polyoxygen to the oil mixture Vinyl ether and rosin are heated and stirred to obtain a mixed solution; the third step is based on the mass ratio of sorbitan monooleate, alkylphenol polyoxyethylene ether, rosin, engine oil, and deionized water at 1: (0.05 ~ 0.15): (0.10~0.15): (3~5): (2~6), add deionized water to the mixture and stir to obtain a water-in-oil emulsion; the fourth step is to make the particle size of 5-10 microns The aluminum powder is added to the water-in-oil emulsion, and 5-10 grams of aluminum powder is added to each liter of the emulsion, and the water-in-oil mixed powder working solut...

Abstract

The invention relates to a water-in-oil type mixed powder working solution which belongs to the field of special processing. The working solution comprises sorbitan monooleate, alkylphenol polyoxyethylene, rosin, machine oil, deionized water and aluminum micropowder. When in preparation, the sorbitan monooleate is added into the machine oil according to the proportion requirement and heated and stirred so that the sorbitan monooleate is dissolved into the machine oil to form a machine oil mixed solution; then, the alkylphenol polyoxyethylene and the rosin are added according to the proportionrequirement and heated and stirred so that the alkylphenol polyoxyethylene and the rosin are dissolved into the machine oil mixed solution; the deionized water is added into the mixed solution and stirred to obtain water-in-oil type emulsion; and finally, the aluminum micropowder is added into the water-in-oil type emulsion and stirred to obtain the prepared water-in-oil type mixed powder workingsolution. The water-in-oil type mixed powder working solution has the advantages of even suspension of solid particles, difficult sedimentation, difficult combustion, no pollution, low cost, safe use, high processing efficiency, high processing surface quality, and the like compared with the conventional kerosene mixed powder solution.

Description

technical field [0001] The invention belongs to the field of special processing and relates to a water-in-oil type powder mixing working fluid. Background technique [0002] At present, the working fluids commonly used in EDM at home and abroad include oil-based working fluids and water-based working fluids. [0003] Oil working fluid mainly includes kerosene, special mineral oil and synthetic oil. Kerosene has high dielectric strength, low viscosity and good fluidity, and is a commonly used working fluid in EDM. However, kerosene has low flash point, high volatility, strong odor, and poor safety, which can easily cause fire accidents. Special mineral oil can overcome some shortcomings of kerosene, but this type of oil contains a certain amount of aromatic hydrocarbons, which leads to poor safety of oil products, odor, and irritating effect on the skin. Synthetic oil mainly includes normal alkanes and isoparaffins. Since no phenolic antioxidants are added, the color of the...
