Abstract

The invention relates to an environment-friendly water-based metal working fluid and a preparation method thereof. The water-based metal working fluid comprises the following ingredients in parts by weight: 15-20 parts of fatty alcohol-polyoxyethylene ether, 15-20 parts of coconut oil fatty acid diethanolamide, 15-20 parts of coconut oil amine polyoxyethylene ether, 3-6 parts of a rosin alcohol solution, 2-5 parts of a synthetic antirusting agent, 0.1-0.2 part of a defoaming agent, 0.3-0.5 part of benzotriazole and the balance of water. The water-based metal working fluid is good in lubricity, high in anti-rust property, high in antibacterial ability, high in stability, and long in service life, does not pollute the environment, is harmless to the human body, and comprehensively satisfies the requirements of highly difficult machining for cutting.

Description

technical field [0001] The invention relates to an environment-friendly water-based metal processing fluid and a preparation method thereof, belonging to the field of metal processing. technical background [0002] At present, most of the traditional metal processing enterprises in China use sodium nitrite and emulsified oil as the main raw materials to make metal processing fluids, and some companies use ordinary oils and emulsifiers to make metal processing fluids. The above metal processing fluids are polluted The environment is easy to deteriorate and smell bad, harmful to people, machine tools, cutting tools and processing materials, and endangering the health of employees. There are also disadvantages such as processing fluid corroding processing materials, high consumption of cutting tools and abrasives, and unstable product quality. [0003] The development of modern machining in the direction of high speed, strength and precision, and the development of difficult-...
