Problems solved by technology

The additive is composed of C8-C30 mixed fatty acids and fatty acid esters, sulfonated castor oil, sulfur and phosphorus modified products of penetrant, sodium chloride, phosphide, dimethyl silicone oil, etc. in a certain proportion. Viscosity oil, for modern high-speed tool grinding, its cooling and filterability cannot meet the requirements, and the grinding oil does not have the advantages of low oil mist and low volatility
[0006] The grinding oils involved in foreign documents TW229126, US57261301995A, and US2002035043 use esters containing dibasic acids and tribasic acids or their derivatives or use alkali metal sulfonates, and there are no reports of oil-suppressing sprays

Abstract

The invention discloses a low oil mist gear grinding oil composition, belonging to the field of metalworking liquid. The composition according to the invention is composed of the following components by weight percent: 70-81% of refined mineral oil, 10-20% of synthesized fatty acid ester oiliness agent, 5-10% of sulfulrized fatty acid ester, 0-3% of phosphate, 0.3-1.0% of oil mist inhibitor and 0.01-0.1% of antifoaming agent; in the composition, the polymer of oil mist inhibitor is innovatively introduced by means of the coordinate proportioning of the refined mineral oil and the fatty acid ester oiliness agent as main component, thus enhancing lubricity, quickening the sedimentation of the oil mist and effectively reducing the concentration of the oil mist in the operating environment, and in addition, lubricating agent and anti-abrasive agent are scientifically proportioned and used, so the composition contains no chlorine which does harm to ecological environment and human body, has strong universality, can be used for processing black and non-ferrous metals and is non-corrosive to copper, therefore, the composition according to the invention not only imparts excellent processing performance to gear grinding oil, but also effectually improves oil mist environment, which is favorable for environmental protection and body health of operating staff.

Description

technical field [0001] The invention relates to a low-oil-mist gear grinding oil composition, which belongs to the field of metal processing fluid products, in particular to metal cutting oil products. Background technique [0002] There are many kinds of metalworking cutting fluids with different functions, but they can be divided into two categories: oil-based cutting fluids and water-based cutting fluids. Oil-based cutting fluid, also known as cutting oil, is usually composed of mineral oil and a certain proportion of additives. The mineral oil used has kerosene, diesel or light lubricating oil fractions. [0003] In the processing of mechanical products, the last process of gear processing is grinding and finishing. Due to the high requirements on the surface of the workpiece, cutting oil is usually used. In order to meet the lubrication and cooling requirements of the gear grinding process, the viscosity of the cutting oil should not be large, generally 8-15mm 2 / s, s...
