Corrosion-resistant cutting fluid and preparation method thereof

Abstract

The invention discloses a corrosion-resistant cutting fluid which is composed of the following components in parts by mass: 10-15 parts of polyvinyl alcohol, 5-10 parts of stearic acid, 3-6 parts of triethanolamine, 5-8 parts of sodium carbonate, 3-5 parts of sodium cumenesulfonate, 120-140 parts of diluted cucumber juice, 1-3 parts of preservative, 0.1-0.5 part of bactericide, 0.1-0.3 part of softener and 0.03-0.06 part of defoaming agent. By selecting excellent materials and adopting the scientific processing method, the corrosion-resistant cutting fluid solves the problems of corrosion, deterioration and smelliness for the machine tool in the past cutting fluid, and can prevent the corrosion, cavitation corrosion and scaling on the machine tool internal surface and form a protective layer. The corrosion-resistant cutting fluid has favorable cooling and lubricating effects, generates fewer precipitates in the use process, and ensures the workpieces to be clean and acceptable. Nitrites and phosphorus and sulfur compounds are eliminated in the product formula, and the cucumber juice is added; and thus, the product is green and environment-friendly. The properties of the product are not changed; and the product has the advantages of high economy, low cost, no toxicity and no adverse effect on skin.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid, and in particular relates to a corrosion-resistant cutting fluid and a preparation method thereof. Background technique [0002] Nowadays, cutting fluid is used when cutting workpieces in machining centers in enterprises. Generally, cutting fluid must meet the four purposes of cooling, lubrication, cleaning, and rust prevention. It can reduce the cutting force during cutting, and take away the heat generated in the cutting area in time. Reduce the cutting temperature, improve the durability of the tool, thereby increasing production efficiency, improving the surface roughness of the workpiece, and ensuring the machining accuracy of the workpiece. The cutting fluid currently used is generally fully synthetic or semi-synthetic or emulsified oil, and the main component is alcohol amine ester Classes, water, surfactants, etc., but heat will be generated during the working process.

[0002] Nowadays, cutting fluid is used when cutting workpieces in machining centers in enterprises. Generally, cutting fluid must meet the four purposes of cooling, lubrication, cleaning, and rust prevention. It can reduce the cutting force during cutting, and take away the heat generated in the cutting area in time. Reduce the cutting temperature, improve the durability of the tool, thereby increasing production efficiency, improving the surface roughness of the workpiece, and ensuring the machining accuracy of the workpiece. The cutting fluid currently used is generally fully synthetic or semi-synthetic or emulsified oil, and the main component is alcohol amine ester Classes, water, surfactants, etc., but heat will be generated during the working process. Alcohol amine ester compounds will be oxidized when the temperature rises, the acidity will increase, and many corrosive substances will be generated, resulting in the deterioration of the cutting fluid and the increase of sediment. It is easy to smell in summer, difficult to dilute in winter, and the anti-rust effect is poor. Some low-end enterprises are still using sodium nitrite as anti-rust agent. Adding water to sodium nitrite has excellent cooling performance, and it is also good for anti-rust, but it will cause workpieces after processing There are white spots on the surface, and sodium nitrite is carcinogenic, causing damage to the operator's body
