Abstract

The invention discloses a high-detergency low-foam semi-synthesis grinding fluid. The high-detergency low-foam semi-synthesis grinding fluid comprises the following components in percentage by weight: 15 to 30 percent of self-emulsifying ester, 5 to 10 percent of organic acid, 10 to 15 percent of organic amine, 10 to 15 percent of an antirust agent, 1 to 2 percent of an emulsifying agent, 0.5 to 1 percent of a surfactant, 2 to 5 percent of a coupling agent, 1 to 2 percent of bactericide and the balance of water. The high-detergency low-foam semi-synthesis grinding fluid provided by the invention has excellent detergency performance and excellent low-foam performance, does not use raw materials such as sodium nitrite, nonyl phenol and boric acid harmful to the environment any more, and enables a product to be environmentally-friendly. The invention also discloses a preparation method of the high-detergency low-foam semi-synthesis grinding fluid.

Description

technical field [0001] The invention relates to a high-cleaning and low-foaming semi-synthetic grinding fluid and a preparation method thereof. Background technique [0002] Grinding is a common metal processing method. The high-speed rotating grinding wheel is used to remove excess material on the workpiece, with small machining allowance and high dimensional accuracy. The matching grinding fluid mainly plays the role of cooling, lubricating, flushing and antirust. The traditional non-water-soluble grinding fluid is composed of base oil plus a small amount of oil-soluble additives. Although it has good lubricity and anti-rust performance, it has a major safety hazard of being flammable. At the same time, the oil mist generated during processing will also affect the operation. The health of workers, so the application of water-based grinding fluid has become more and more common recently. Water-based grinding fluids are basically divided into semi-synthetic and fully synth...
