The invention relates to a water-soluble
cutting fluid, which comprises the following
raw material components by weight: 3-5% of monoethanolamine, 5-8% of
triethanolamine, 2-5% of
boric acid, 3-5% ofsebacic acid, 2-5% of
tribasic acid, 15-25% of 25#
transformer oil, 4-6% of
pentaerythritol ester, 5-12% of a T702 anionic surfactant, 5-8% of a
nonionic surfactant, 0.1-0.8% of a
copper corrosion inhibitor, 0.3-1.0% of an
aluminum corrosion inhibitor, and the balance of water. According to the present invention, the water-soluble
cutting fluid is the universal water-soluble anti-
hard water cutting fluid; the
processing range of the water-soluble
cutting fluid is wide, wherein the water-soluble
cutting fluid can process
cast iron, steel, stainless steel,
copper alloys, aluminum alloys and a variety of
metal materials; the water-soluble
cutting fluid is generally suitable for
soft water and
hard water, can be used in all parts of the country, and has excellent hard-
water resistance, whereinthe water-soluble cutting fluid can
resist the
hard water in Shandong area (the hard water rang is 500-1300); and with the independently researched and developed anticorrosion
system, the product does not produce deterioration and
odor changing within the service life of 1 year, and is environment-friendly .
