Problems solved by technology

The former is mainly composed of water, mineral oil and emulsifier, which is characterized by good lubricating performance, but poor in stability and permeability, prone to mildew and odor, and short service life; the latter is mainly composed of various water-soluble Additives (such as lubricants, extreme pressure anti-wear agents, anti-rust agents, surfactants, etc.) Stability, long service life, and positive significance in terms of environmental protection and energy saving. It is the mainstream of cutting (grinding) fluid development, and it is also a hot spot in research and development at home and abroad.
CN86102438 discloses an oil-free cutting fluid that does not contain mineral oil, which is characterized by low cost, simple preparation, no pollution, and harmlessness, but still has problems such as short service time and poor lubrication and rust resistance; CN91105163 discloses a long-life synth...

Abstract

The invention relates to a multi-effect water-based composite cutting/grinding fluid which consists of water-soluble oil, cleaning agent, extreme pressure antiwear agent, antirust, antibacterial agent, complexant, solubilizer and anstatic agent. The water-soluble oil is the mixture of aminoethyl alcohol and triethanolamine oleate, the cleaning agent is anionic surfactant or nonionic surfactant, the extreme pressure antiwear agent is one or two of additives A, B, C, D, E and F, the antirust is benzotriazole and sodium benzoate, the antibacterial agent is boric acid and borax, the complexant is EDTA and the solubilizer is urea. The cutting/grinding fluid with various improved performances is non-toxic and tasteless, is an environment-friendly product and has no harm to human body and the skin of users; the operating cycle is normally more than 6 months.

Description

technical field [0001] The invention relates to a cutting (grinding) fluid for metal processing, which belongs to the preparation method of a high-water base type high-efficiency, low-cost and multi-purpose cutting (grinding) fluid. Background technique [0002] The cutting fluid with excellent performance has good cooling, lubricating, cleaning and anti-rust properties, and has a significant effect on improving the quality and efficiency of cutting processing and reducing tool wear. At present, the water-soluble cutting fluids used at home and abroad are mainly divided into emulsified cutting fluids and water-based synthetic cutting fluids. The former is mainly composed of water, mineral oil and emulsifier, which is characterized by good lubricating performance, but poor in stability and permeability, prone to mildew and odor, and short service life; the latter is mainly composed of various water-soluble Additives (such as lubricants, extreme pressure anti-wear agents, ant...
