Multiple-effect type water-based synthesized cutting solution and preparation thereof

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...

AI Technical Summary

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 synthetic cutting fluid , excellent performance, but because it contains bactericide, there are certain toxic and side effects; CN94108478 discloses sulfide water-based cutting fluid, the performance of its cutting fluid is all excellent, but the raw material cost of its composition is high, and contains sulfide, to The environment has a certain impact; CN1459493 discloses a long-lasting synthetic cutting fluid with excellent performance, but the No. 1 monomer, No. 2 monomer, and No. 3 monomer in the composition are all reacted at 500 ° C, which consumes a lot of energy; CN1746281, CN1746282 disclose environment-friendly type cutting (grinding) cutting fluid, it has lubricating, extreme pressure anti-wear, good anti-rust performance, nontoxic, harmless to human body, environmental protection, the characteristic of long service life, but due to adding more expensive molybdate, polyether compounds, high product cost
