Problems solved by technology

[0003] At present, there are many wire-cut emulsion products on the market, which meet the demand to a certain extent. However, the treatment of the used wire-cut emulsion is relatively difficult, and the discharge of waste liquid has caused serious pollution to the environment. With the environmental protection requirements As well as the improvement of the surface quality requirements of the wire cutting process, there is an urgent need to develop a biodegradable and environmentally friendly wire cutting emulsion

Embodiment 1

[0016] Add 60 parts of deionized water, 6 parts of triethanolamine oleic acid soap, and 0.01 parts of colloidal graphite powder to the flask in turn, heat and stir at 60°C for 30 minutes to obtain Liquid A; add 0.1 part of Tween 60 emulsifier, 0.02 part of benzalacetone, 1 One part of sodium citrate, 0.01 part of 4-methylbenzotriazole, 0.2 part of polyoxypropylene oxyethylene glycerol ether, and 0.2 part of polyvinyl alcohol were added to 2 parts of biodiesel in sequence and mixed uniformly to obtain Liquid B; Liquid A was kept at 1000rpm Under speed shearing and stirring, slowly add liquid B dropwise to liquid A, then adjust the pH of the system to 8.5, and stir for 30 minutes at a temperature of 35°C and 3000 rpm to obtain a wire cutting emulsion, which is diluted with deionized water for 10 Times, the production efficiency can reach 38mm when cutting cast iron materials 2 / min, processing surface roughness R a Up to 0.5μm.

Embodiment 2

[0018] 70 parts of deionized water, 9 parts of triethanolamine oleic acid soap, 0.01 parts of colloidal graphite powder were sequentially added to the flask, heated and stirred at 80°C for 40 minutes to obtain Liquid A; 1 part of Tween 60 emulsifier, 0.04 part of benzalacetone, 1 part One part of sodium citrate, 0.05 part of 4-methylbenzotriazole, 0.6 part of polyoxypropylene oxyethylene glycerol ether, 1.2 part of polyvinyl alcohol were added to 6 parts of biodiesel in sequence and mixed uniformly to obtain Liquid B; Liquid A was kept at 500rpm Under rotational speed shearing and stirring, slowly add liquid B dropwise to liquid A, then adjust the pH of the system to 8.8, and stir for 40 minutes at a temperature of 50°C and 4000 rpm to obtain a wire cutting emulsion, which is diluted with deionized water during use. Times, the production efficiency can reach 29mm when cutting alloy tool steel materials 2 / min, processing surface roughness R a It can reach 0.58μm.

Abstract

The invention discloses biodegradable environment-friendly line-cutting emulsion liquid and a preparation method thereof. The emulsion liquid is prepared from the following raw materials in parts by weight: 60-80 parts of deionized water, 5-12 parts of triethanolamine oleic soap, 0.001-0.02 part of colloidal graphite powder, 0.2-8 part of biodiesel, 0.05-2 parts of a tween-60 emulsifier, 0.01-0.8 part of benzylidene acetone, 1-2 parts of sodium citrate, 0.01-0.1 part of 4-methylbenzotriazole, 0.2-0.8 part of polyoxypropylene oxyethylene glycol ether and 0.1-2 parts of polyvinyl alcohol; the preparation method comprises the steps of mixing the components in two steps, finally adjusting the pH of emulsion liquid, and evenly stirring to obtain the biodegradable environment-friendly line-cutting emulsion liquid. The product prepared by the method is environmentally friendly, biodegradable in components and simple and convenient in preparation method; the biodegradable environment-friendly line-cutting emulsion liquid has the obvious effects of cooling, preventing rust, increasing efficiency and improving processing surface quality in an electro-spark wire-electrode cutting process, thus having good promotional value.

Description

1. Technical Field [0001] The invention relates to the field of emulsions for mechanical processing wire cutting, in particular to a biodegradable environment-friendly wire cutting emulsion and a preparation method thereof. 2. Background technology [0002] The machining process includes multiple processes. Wire EDM is a machining method in which thin metal wires are used as electrodes, and the mechanical parts are pulsed by continuous movement of the wire to cut metal. In order to reduce the temperature of the cut surface, prevent rust on the fresh surface, increase processing efficiency, and improve the quality of the processed surface, wire cutting emulsions are usually used in the processing process to achieve the above goals. [0003] At present, there are many wire-cutting emulsion products on the market, which meet the demand to a certain extent. However, it is difficult to treat the wire-cutting emulsion after use, and the discharge of waste liquid has caused serious pollut...
