Abstract

The invention relates to a metal machining liquid which comprises the following elements in parts by weight: 65 parts of deionized water, 25 parts of a lubricant additive, 1 part of an antirust agent, 1 part of a calcium magnesium ion softener, 5 parts of lauric acid, 2 parts of polyvinyl ether, 0.1 parts of high alcohol and 2 parts of a surfactant. All the additives in the prescription of the metal machining liquid provided by the invention are the additives with rather fast biological degradation speed, so the machining liquid is environment-friendly and does not cause environmental pollution; besides, the machining liquid has no physiological toxicity, so the machining liquid is a rather ideal metal machining liquid friendly to the environment.

Description

technical field [0001] The invention belongs to the field of lubricating oil, in particular to a metal cutting fluid. Background technique [0002] At present, most metal cutting fluids are prepared with a lot of additives like sodium nitrite or heavy metals. These substances are not only carcinogens, but also the discharge of working fluid waste also causes great pollution to the environment. In recent years, with the continuous strengthening of people's environmental awareness and environmental legislation, the requirements for metalworking lubricants have become more and more stringent. Therefore, it is urgent to develop new environmentally friendly metalworking fluids. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art and provide a metal cutting fluid with simple process and safe production. [0004] The present invention solves its technical problem and realizes by taking the following technical so...
