Abstract

The invention provides an anti-emulsification rust-proof quenching oil composition and a preparation method of the anti-emulsification rust-proof quenching oil composition. The anti-emulsification rust-proof quenching oil composition comprises, by mass percentage, 90.2-96.63% of paraffin-based base oil, 1.8-7.9% of polyolefin, 0.025-0.1% of petroleum sulfonic acid soap, 0.02-0.1% of triethanolamine soap, 0.025-0.1% of polyether and 0.5-1.5% of antioxidant. According to the anti-emulsification rust-proof quenching oil composition, the triethanolamine soap is introduced into the anti-emulsification rust-proof quenching oil composition, and the triethanolamine soap is blended with the polyether and the polyolefin to realize emulsification prevention and rust prevention. The anti-emulsification rust-proof quenching oil composition has the beneficial effects of water film replacement rust prevention and good dewatering and clarifying performance, the composition is thoroughly mixed with water, and after the sedimentation and drainage, the oil layer has good clarification and less water and can be reused in a quenching oil tank.

Description

technical field [0001] The invention relates to the technical field of quenching oil, in particular to an anti-emulsification and anti-rust type quenching oil composition and a preparation method thereof. Background technique [0002] In the heat treatment process using quenching oil as the quenching medium, in the quenching and tempering heat treatment process of metal parts, before the workpiece enters the tempering furnace, it must go through a water washing process to clean the quenching oil on the surface of the workpiece. After cleaning, the damp quenched workpiece must not rust during tempering. The quenching oil that has been cleaned must have good sedimentation and drainage performance. The quenching oil that has been cleaned and recovered can only be reused in the quenching oil tank after sedimentation and drainage, saving about 40% of the consumption of quenching oil. If the settling and drainage performance of the quenching oil is poor, the quenching oil recover...
