Embodiment 1
[0024] A kind of quenching oil that can make bearing steel self-blacken after quenching is characterized in that: its composition and the mass fraction of each component are: refined base oil (kinematic viscosity 28-42mm 2 / s, pour point ≤ -9°C, acid value ≤0.02mgKOH / g) 18 parts, 0.3 parts of cooling compounding agent, 0.16 parts of blackening compounding agent, 0.3 parts of brightener, 1.24 parts of surfactant.
[0025] The cooling compounding agent is a mixture of polyisobutylene and EPDM, wherein the mass ratio of polyisobutylene to EPDM is 2:1; the blackening compounding agent is a mixture of acrylate, dyeing agent and wetting agent , wherein the mass ratio of acrylate, colorant (Black AFR, oily colorant produced by BASF) and wetting agent (oil-soluble azone) is 1:2:1; described brightener is petroleum sulfonate and A mixture of dibasic acids, wherein the mass ratio of petroleum sulfonate to dibasic acid is 1:2; the surfactant is oily phenolic resin.
