Environment friendly quenching agent used for abrasion-resistant alloy machining and preparation method thereof

Abstract

The invention discloses an environment friendly quenching agent used for abrasion-resistant alloy machining. The environment friendly quenching agent used for abrasion-resistant alloy machining is composed of the following raw materials including, by weight, 5-13 parts of ethyl alcohol, 2-7 parts of acetic acid ester, 0.5-1.4 parts of stearic acid, 7-10 parts of sodium sulfate, 2-4 parts of potassium hydroxide, 15-26 parts of sweet potato starch, 3-8 parts of 6-acetyl oxygen methyl-2,2-dimethyl-1,2-dioxolame-tert-butyl acetate, 5-10 parts of D-aspartic acid, 10-17 parts of palm oil and 8-12 parts of polyethylene glycol. The stearic acid, the sweet potato starch and the palm oil are dissolved in ethyl alcohol firstly, and a mixed solution is obtained; then the mixed solution is added with water and transferred into a reaction still; after the reaction is finished, temperature reduction is conducted, the acetic acid ester and the 6-acetyl oxygen methyl-2,2-dimethyl-1,2-dioxolame-tert-butyl acetate are added, and still standing is conducted after stirring; then centrifugation is conducted, and a liquid supernatant is taken after centrifugation; and the sodium sulfate, the potassium hydroxide, the D-aspartic acid and the polyethylene glycol are added, temperature rising, thermal insulation, temperature reduction and mouth sealing through paraffin oil are conducted after even stirring, and the environment friendly quenching agent is obtained. The prepared environment friendly quenching agent used for abrasion-resistant alloy machining can greatly improve abrasive resistance of alloys.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an environment-friendly quenching agent for wear-resistant alloy processing. Background technique [0002] Quenching agent is a process oil used as a quenching medium. The quenching agent must have the following characteristics: good cooling performance, high flash point and ignition point, good thermal oxidation stability, low viscosity, and low moisture content. In addition to the above characteristics, the quenching agent should also be non-toxic, odorless, easy to handle, non-polluting to the environment, and make the surface of the quenched workpiece bright. According to the cooling rate, it can be divided into: (1) ordinary quenching agent; (2) fast quenching agent; (3) super (high) speed quenching agent. Ultrafast quenching agents have a fairly fast cooling rate, faster than rapid quenching agents. The oil is prepared by adding refrigerant, detergent and antioxidant t...

Problems solved by technology

In use, the organic solution will accelerate aging after being heated, and its cooling characteristics will change. If it is not replaced in time, the quality of the heat-treated product will be reduced, or even unqualified.

At present, there is no uniform quenching ag
