Abstract

The invention discloses hard water-resistant semi-synthetic metal cutting fluid and a preparation method thereof. The hard water-resistant semi-synthetic metal cutting fluid comprises: by weight, 20 to 30% of base oil, 30 to 50% of a nonionic surfactant, 5 to 10% of an anionic surfactant, 5 to 8% of one or more antirust agents, 3 to 4% of a couplant, 0.5 to 1% of a corrosion and scale inhibitor, 5 to 6.9% of an extreme-pressure agent, 0.3 to 0.5% of an antifoaming agent, 0.2 to 0.5% of a bacteriacide and the balance water. The hard water-resistant semi-synthetic metal cutting fluid can resisthard water of 800ppm, is widely suitable for regions having high water hardness, realizes direct use of dilution water without water softening treatment, has a long service life of more than 2 years,and has excellent performances of lubricity, rust resistance, cooling performances and defoaming performances.

Description

technical field [0001] The invention relates to a hard water resistant semi-synthetic metal cutting fluid and a preparation method thereof. Background technique [0002] When the existing metal cutting fluid is used, the concentrated solution needs to be prepared into a high water-based dilution solution with water. Due to its formula and other reasons, it is not resistant to hard water, and the use of hard water will cause the quality of cutting fluid to decline, increase the processing cost, and bring trouble to use. At the same time, there are also unsatisfactory aspects such as lubricity, rust prevention, cooling, and defoaming performance. purpose of invention [0003] The object of the present invention is to provide a hard water resistant semi-synthetic metal cutting fluid and a preparation method thereof. [0004] Technical scheme of the present invention [0005] A semi-synthetic metal cutting fluid resistant to hard water, wherein each raw material com...
