Problems solved by technology

However, choosing vegetable oils and esters as base oils often requires special attention to their service life; choosing white oil, diesel oil, and engine oil as base oils is prone to problems such as strong odor, poor cleaning and emulsification stability; Alkylphenol polyoxyethylene ether as an emulsifier may cause potential water hazards (nonylphenol polyoxyethylene ether has been banned in Europe); petroleum sulfonate Sodium bicarbonate as an emulsifier brings the risk of corruption and deterioration; choosing ethanol and ethylene glycol monobutyl ether as an auxiliary agent brings about problems such as high volatility, poor product stability, unfriendly smell, foaming and peeling of machine tool paint; sterilization and mildew prevention The combination of components is unreasonable, and the service life of the emulsion bath is too short; the product relies too much on defoamers to eliminate foam, which is not suitable for high pressure and severe filtration systems

[0027] Dilute the emulsion prepared in Example 2 to a mass percentage concentration of 8%-10%, and use it in the scraping and rolling process of the inner wall of the hydraulic cylinder to effectively protect the balls and rollers. The roughness of the inner wall is up to standard, and the anti-rust period is ...

Embodiment 3

[0030]An emulsion, prepared from the following components by weight percentage: 4% tall oil fatty acid, 8% tap water, 6% organic alcohol amine, 4% fatty acid amide, mixed and stirred for 15 minutes (until the mixture is clear and transparent) Then add naphthenic oil 43.3%, sulfurized fatty acid ester 15%, polymer ester 5%, methyl-benzotriazole 0.2%; 1,2-benzisothiazol-3-one 3 %; Iodopropynyl butyl carbamate 0.5%; Fatty alcohol alkoxylate 3%; C12-C18 isomeric fatty alcohol 1%, Tween-802%, Siben-805%, just stir well.

[0031] The emulsion prepared in Example 3 is clear and transparent, and meets the relevant performance standards of SH / T0365 and GB / T6144-2010.

[0032] Dilute the emulsion prepared in Example 3 to a concentration of 8%-10% by mass, and use it for sawing of alloy steel rods with tungsten carbide saw blades. Lubricating oil is equivalent when processing. The emulsion of the present invention can effectively reduce the generation of oil mist on site and greatly re...

Abstract

The invention discloses emulsified liquid capable of replacing oil products. The emulsified liquid is prepared from the following components in percentage by weight: 30%-55% of naphthenic base oil, 10%-35% of an extreme-pressure lubricant, 0-10% of an oily lubricant, 2%-5% of an anionic emulsifier, 5%-12% of a nonionic emulsifier, 2%-10% of organic alcohol amine, 5%-10% of a rust inhibitor, 0.1%-1% of a copper corrosion inhibitor, 0-4% of a bactericide, 0-1% of a mildew preventive, 0-3% of a coupling agent and 0-10% of water. The formula of the emulsified liquid does not contain silicon, boron, phosphorus and formaldehyde, and the emulsified liquid is safe and environmentally friendly; on the other hand, by virtue of the emulsified liquid, the processing effects of the oil products can be realized, but the cost of the emulsified liquid is far lower than the costs of the oil products, so that the production cost of a user can be greatly lowered by virtue of the emulsified liquid.

Description

technical field [0001] The invention relates to a metal processing medium used for lubricating, cooling, cleaning and storing between processes to prevent corrosion during forming and cutting, in particular to an emulsion and a preparation method of the emulsion. Background technique [0002] In the metalworking industry, metal cutting fluids are widely used. Reasonable selection of metal cutting fluid can improve the friction between the workpiece and the cutting tool, reduce the cutting force and cutting temperature, reduce the thermal deformation of the workpiece, improve the machining accuracy and reduce the roughness of the machined surface. Similarly, the use of forming fluid in the metal forming process can improve the life of the mold and ensure the processing quality. Metal forming fluids and cutting fluids are divided into pure oil products, emulsions, semi-synthetics, and full-synthetics according to their oil content. In recent years, with the increasing requir...
