Problems solved by technology

[0003] The existing quenching oil generally uses mineral oil as the base oil. The development and refining process of mineral oil produces a large amount of carbon emissions, and the degradation rate is less than 20%. It is not easy to biodegrade and is not environmentally friendly.
Moreover, a large amount of petroleum resin additives are used in the existing quenching oil, which has a large smell and a large environmental pollution

Abstract

The invention discloses low-carbon environment-friendly biodegradable quenching oil which comprises the following components: 80-90% of dioctyl terephthalate; 0-10% of isooctyl palmitate; 0-10% of isooctyl stearate; 0-5% of PIB1300; and 0-5% of PIB2400. The invention further discloses a preparation method of the low-carbon environment-friendly biodegradable quenching oil. Compared with the prior art, the quenching oil has the advantages of being high in cooling speed, easy to biodegrade, low in carbon, environmentally friendly and the like due to the replacement of not-easy-to-degrade mineral oil by DOTP (dioctyl terephthalate) in any proportion, the adoption of DOTP in any proportion as base oil, the combination of DOTP and an additive as well as the special compounding proportion.

Description

technical field [0001] The invention belongs to the field of quenching oil, and in particular relates to a low-carbon, environment-friendly, biodegradable quenching oil and a preparation method thereof. Background technique [0002] The cooling medium used in the quenching process is called the quenching medium, and the quenching medium plays an important role in ensuring the implementation of the quenching process. Quenching medium mainly includes liquid quenching medium, gas quenching medium and solid quenching medium, liquid quenching medium mainly includes water, aqueous solution, quenching oil, gas quenching medium mainly includes air and inert gases such as nitrogen, argon, helium, and solid quenching medium mainly includes metal Fluidized bed medium composed of plates, metal molds (internal water cooling) and solid particles mixed with compressed air or water. [0003] Existing quenching oil generally uses mineral oil as the base oil. The development and refining pro...
