Fully synthetic water-based stainless steel cutting fluid, preparation method and use method thereof

Abstract

The invention discloses a totally-synthesized water-based stainless steel cutting liquid. The cutting liquid contains the following components: a stainless steel water-based extreme-pressure agent, caprylic-capric acid, boric acid triethanolamine ester, polyethylene glycol, a cation quaternary ammonium salt metal filings settling agent, a dicarboxylic compound antirusting agent, a monobutyl ether coupling agent, a hard-water-resisting agent, a defoamer and distilled water. By virtue of an environmental-friendly total-synthesis formula, the cleaning and settling properties of the cutting liquid are enhanced; an environmental-friendly special water-based extreme-pressure lubricant is used to substitute for the traditional synthetic ester, thereby ensuring the long-time stability of the cleaning and settling properties of the cutting liquid. The cutting liquid plays a very good role in protecting non-ferrous metal and ferrous metal; by virtue of the cation quaternary ammonium salt settling agent, the problem of iron filings settling during the processing of stainless steel is eliminated, and the transparency and stability of the cutting liquid in long-time use are guaranteed.

Description

technical field [0001] The invention relates to the technical field of water-based metal processing lubrication and anti-rust technology, in particular to the preparation and use method of a fully synthetic water-based stainless steel cutting fluid. Background technique [0002] Stainless steel has been widely used due to its advantages of high strength, high wear resistance and low expansion coefficient. Because stainless steel has high tensile strength, yield strength, elongation and impact value in terms of mechanical properties, and its high temperature strength and hardness are also high, in addition, stainless steel also has high corrosion resistance and high temperature resistance. Therefore, it is widely used in industrial sectors such as machinery, petrochemical industry, electronic instrumentation, and national defense. In terms of physical properties, its conduction hot spot is low. Due to these properties, its cutting process has the following four characteristi...

Problems solved by technology

Water-soluble cutting fluid is divided into emulsion and synthetic fluid. Although synthetic fluid is the best in terms of cooling performance, its lubricity is poor. It is difficult to form an ideal lubricating film during processing, and it is easy to produce tool surface The direct contact with the workpiece forms the so-called dry friction, which makes the contact length between the knife and the chips longer and the shear angle smaller, thus increasing the difficulty of cutting

Therefore, it is difficult to meet the requirements of stainless steel cutting with boundary lubrication in cutting.

The lubricity and cooling properties of emulsified oil are between oil agents and synthetic fluids. However, ordinary emulsified oils have general cooling properties and are prone to corruption and odor due to their large oil content, so it is difficult to meet the special processing requirements of stainless steel processing.

[0006] Therefore, there is a need for a cutting fluid used in stainless steel processing, whose lubricating performance, corrosion resistance and cleaning performance can match for a long time, solve the lubrication problem in the stainless steel processing process; solve the tool wear problem; solve the environmental protection problem of waste liquid discharge
