Problems solved by technology

Emulsified cutting fluid has good lubricating performance, but poor cooling, permeability, and stability, short service life, environmental protection problems when discharged, non-biodegradable, and prone to mildew and odor; water-based synthetic cutting fluid In terms of performance, it has good cooling, cleaning and stability, and has positive significance in terms of environmental protection and saving oil resources. It is the mainstream of cutting fluid development.
[0004] However, there are many types of water-soluble cutting fluids in the prior art, and the products are uneven. Some products have not been used for a long time, some products have poor anti-rust performance, some products have unsatisfactory lubricating effects, and some products have peculiar smell and strong smell. bad smell

Abstract

The invention discloses water-soluble cutting fluid. The water-soluble cutting fluid contains the following ingredients in parts by weight: 8-9 parts of coconut oil, 8-9 parts of sorbitol, 13-15 parts of polyethylene glycol, 3-5 parts of dodecanedioic acid, 3-5 parts of boric acid, 0.1-0.2 part of benzotriazole, 2-3 parts of ricinoleic acid, 8-15 parts of tetrapolyricinoleic acid, 3-5 parts of DIACID1550, 2-3 parts of sodium gluconate, 2-3 parts of alkyl glycoside, 2-4 parts of protease, 0.3-0.8 part of bactericide, 0.1-0.2 part of antifoamer and the balance of water. The water-soluble cutting fluid prepared from the raw materials has the advantages of good rust resistance, no off flavor, no smelling, long service time and convenience in used treatment. The invention also discloses a preparation method for the water-soluble cutting fluid.

Description

technical field [0001] The invention relates to a water-soluble cutting fluid. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute. It overcomes the shortcomings of traditional soap-based emulsions, which are easy to smell in summer, difficult to dilute in winter, and poor in anti-rust effect, and has no adverse effect on lathe paint. [0003] According to the chemical composition of oil, cutting fluid is divided into two categories: non-water-soluble (oil-based) fluid and water-soluble (water-based) fluid. Water-based cutting fluid can be divided into emulsion, semi-synthetic cutting fluid and fully synthetic cutting fluid. Emulsified cutting fluid has good lubricating performance, but poor cooling, permeability, and stability, s...
