Problems solved by technology

[0005] Existing polyether coupling agents mostly use single-component low-carbon chain monobasic acids or dibasic acids as coupling agents, which have disadvantages such as large odor, large foam, and insolubility in water; and the coupling effect is poor under high alkaline conditions, and the amount of addition Large, and a large amount of addition will greatly reduce the alkalinity of the system, thus affecting the rust inhibitor and cleaning ability of cutting fluid or cleaning agent

Abstract

The invention discloses a water-based polyether coupling agent and a preparation method thereof. The water-based polyether coupling agent is prepared from a benzoic acid, a p-tert-butyl benzoic acid, an acylamino acid, a fatty alcohol polyoxyethylene ether carboxylic acid, an organic acid, organic amine, inorganic base and deionized water. The blended water-based polyether coupling agent has the characteristics of high coupling capability on polyether in a high alkaline environment and low additive amount, has a higher coupling capability than a single-component coupling agent, and also has certain antirust property and cleaning property; the additive amount of an antirust agent and a surfactant in a cutting fluid or a cleaning agent can be reduced and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a metal working fluid, a cleaning agent, and the like for metal cutting, processing, and forming processes, and belongs to the technical fields of metal cutting, forming, cleaning, and the like. Background technique [0002] With the development of modern mechanical processing in the direction of high speed, strength and high precision, modern harsh processing conditions have put forward higher and higher requirements for the quality of cutting fluid, especially for the lubrication and low foaming of cutting fluid in high-speed grinding machine processing. higher requirement. As a kind of cutting fluid, the grinding fluid plays the role of cooling, cooling, lubricating and washing for the grinding of high-precision parts, and also has a certain influence on the improvement of production efficiency and the stable control of the precision of processed parts. Therefore, its Low foam requirements are higher. In addition, in order...
