Abstract

The invention discloses a grinding fluid special for a hard alloy. The grinding fluid is characterized by consisting of the following components in percentage by mass: 6 to 20 percent of cyclohexyl diethanolamine, 10 to 20 percent of organic acid, 1 to 3 percent of benzotriazole derivative, 6 to 15 percent of polyether modified ester, 0.5 to 5 percent of potassium hydroxide, 3 to 5 percent of a coupling agent, 1 to 2 percent of bactericide, 0.1 to 0.5 percent of a polyether modified silicon defoamer and the balance of water. The organic acid is at least one of tricarboxylic acid, undecanedioicacid and sebacic acid; the polyether modified ester has a structure shown in the specification, wherein n is 5-15, and R is an 18-carbon alkyl group; wherein the coupling agent is at least one of neodecanoic acid, isocaprylic acid and isononanoic acid.

Description

technical field [0001] The invention belongs to the technical field of lubricating and cooling for hard alloy processing, and in particular relates to a special grinding fluid for hard alloy which is friendly to the environment, can inhibit cobalt precipitation and has a long service life. Background technique [0002] Cemented carbide has exceptionally high hardness, excellent wear resistance and corrosion resistance even at extremely high temperatures, and is widely used in molds, knives, etc. Cemented carbide will generate a lot of heat during the grinding process, and it needs to use grinding fluid to dissipate heat. Due to the poor heat dissipation of oil-based grinding fluid, it is easy to cause high-temperature burns to the workpiece and the operating environment is harsh, so the grinding of cemented carbide usually uses water-based grinding fluid with good cooling performance. At present, there are many problems in the commercially available cemented carbide water-b...
