Coolant for aluminum alloy processing

Abstract

The invention discloses a coolant for aluminum alloy processing. The coolant is prepared from components in parts by mass as follows: 20-30 parts of stearate, 5-10 parts of low-silicon acidized triethanolamine, 4-8 parts of sodium dodecyl sulfate, 5-8 parts of organic silicone oil, 3-5 parts of dodecenylsuccinic acid, 8-15 parts of a sodium hydroxide solution with the concentration being 55%, 0.1-0.2 parts of diethyl acetate tetrahydrate and 40-50 parts of wheat grass juice. The selected materials are excellent, the coolant is formed through high-temperature and high-pressure composition with the scientific processing method and is high in antibacterial capacity, good in antirust effect and free of layering, the problems of cutting fluids corrode machine tools, deteriorate and stink in the past are solved, few precipitates exist during usage, the product is clean and qualified, nitrite, phosphorus and sulfur compounds are eliminated in the product formula, the wheat grass juice is added, and the product is environment-friendly, economical, low in cost and non-toxic, causes no harmful effects on skin, can significantly improve the finish of processed surfaces and provide good antirust protection for parts and is applicable to cutting of black metals, aluminum and aluminum alloys.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid, and in particular relates to a cooling fluid for aluminum alloy processing. Background technique [0002] Nowadays, when cutting aluminum alloy workpieces in enterprises, heat and debris will be generated. In order to ensure the processing quality, it is necessary to choose coolant according to the different processing materials during processing. In order to meet the purpose of cooling, lubrication, cleaning and rust prevention, from practical Generally speaking, kerosene can be used as a coolant, but the cleaning of kerosene is a problem, and it has been phased out now. Currently, fully synthetic or semi-synthetic or emulsified oil coolants are generally used. The main components are alcohol amine esters, water, surface Active agents and other things, but heat will be generated during the working process. Alcohol amine ester compounds will be oxidized when the temperature rises, the acidi...

[0002] Nowadays, when cutting aluminum alloy workpieces in enterprises, heat and debris will be generated. In order to ensure the processing quality, it is necessary to choose coolant according to the different processing materials during processing. In order to meet the purpose of cooling, lubrication, cleaning and rust prevention, from practical Generally speaking, kerosene can be used as a coolant, but the cleaning of kerosene is a problem, and it has been phased out now. Currently, fully synthetic or semi-synthetic or emulsified oil coolants are generally used. The main components are alcohol amine esters, water, surface Active agents and other things, 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. Difficult to dilute, poor anti-rust effect, some low-end enterprises are still using sodium nitrite as anti-rust agent, sodium nitrite is added with water, the cooling performance is excellent, and the anti-rust effect is also good, but it will cause white spots on the surface of the workpiece after processing, and Sodium nitrite causes cancer and causes damage to the operator's body
