Abstract

The invention relates to an oil product of a petrochemical product, and in particular relates to rapid bright quenching oil and a preparation method thereof. The rapid bright quenching oil is prepared from the following components in percentage by weight: 75% of deeply refined mineral oil as basic oil, 6% of a brightener, 3.7% of a refrigerant, 8% of an antioxidant, 2.3% of a cake-preventing agent and 5% of animal and plant oil. The rapid bright quenching oil is low in cost and good in cooling property, brightness and thermal oxidation stability, and the surface of a quenched workpiece is bright and free of crack.

Description

technical field [0001] The invention relates to oil products of petrochemical products, in particular to a rapid bright quenching oil and a preparation method thereof. Background technique [0002] Quenching oil is a process oil used as a quenching medium. Although the commonly used commercial quenching oil has good performance, its price is high (generally 13,000-16,000 per ton), which increases the burden on enterprises. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, and provides a fast bright quenching oil with low cost, good cooling performance, brightness and thermal oxidation stability, bright surface of the workpiece after quenching, and no cracking. [0004] In order to solve the above-mentioned technical problems, the present invention is solved through the following technical solutions: a kind of rapid bright quenching oil, which adopts mineral oil as base oil, adds refrigerant, brightener, scorch inhibitor, a...
