Abstract

The invention relates to a tempering oil composition and a preparation method thereof, and can be used for mainly solving the problems in the prior art that the tempering oil does not have an antirust property for a workpiece, the ordinary antirust agent is not matched with other components in the tempering oil, and the antirust property is poor. The tempering oil composition comprises the following components in parts by weight: a) 0.5 to 8 parts of antirust agent; b) 0.1 to 8 parts of cleaning dispersion agent; c) 0.05 to 3 parts of antioxidant; d) 0.001 to 3 parts of brightening agent; e) 75 to 98 parts of basic oil; the antirust agent is selected from at least one of sulfonate or dodecenylsuccinic acid; the cleaning dispersion agent is selected from at least one of alkenyl succinimide, polyisobutene bissuccinimide, polyisobutene poly-succinimide or macromolecular succinimide; the antioxidant is selected from at least one of phenolic antioxidant or amine antioxidant; the brightening agent is selected at least one of imidazoline oleate or methyl terpene resin. By adopting the technical scheme, the problems can be well solved, and the tempering oil composition can be used for the low-temperature tempering process of different components in the automobile industry, the bearing industry and the tool industry.

Description

technical field [0001] The invention relates to a tempering oil composition and a preparation method thereof. Background technique [0002] Tempering, also known as tempering, is a metal heat treatment process in which the quenched workpiece is reheated to an appropriate temperature lower than the lower critical temperature, and after a period of heat preservation, it is cooled in air, water or oil. Its purpose is mainly to reduce or eliminate the internal stress generated during quenching, or reduce the hardness and strength of the workpiece to improve its ductility or toughness. The tempering process includes high temperature tempering (500~600°C), medium temperature tempering (300~400°C) and low temperature tempering (160~260°C). The corresponding tempering heating equipment generally adopts electric furnace, salt bath furnace and oil bath stove. Usually, only oil is used as a medium for low temperature tempering, which is called tempering oil. In the industry standard...
