Abstract

The invention discloses a quenching agent for abrasion-resistant alloy processing. The quenching agent for abrasion-resistant alloy processing comprises, by weight, 5-13 parts of polyether, 2-7 parts of laurate, 0.5-1.4 parts of stearic acid, 7-10 parts of sodium benzoate, 2-4 parts of potassium chloride, 15-26 parts of corn starch, 3-8 parts of 6-acetyl oxygen methyl-2,2-dimethyl-1,3- dioxolame-tert-butyl acetate, 5-10 parts of D-aspartic acid, 10-17 parts of palm oil, and 8-12 parts of polyethylene glycol. Firstly, the stearic acid, the corn starch and the palm oil are dissolved in the polyether, so that mixed liquor is obtained; secondly, water is added, the mixed liquor is transferred into a reaction kettle, after the reaction is completed, the temperature is decreased, the laurate and the 6-acetyl oxygen methyl-2,2-dimethyl-1,3- dioxolame-tert-butyl acetate are added, and standing is conducted after stirring; thirdly, centrifugation is conducted, supernate is obtained after centrifugation, the sodium benzoate, the potassium chloride, the D-aspartic acid and the polyethylene glycol are added, the temperature is increased, maintained and then decreased after even stirring, sealing is conducted through paraffin oil, and then the quenching agent is obtained. The prepared quenching agent can greatly improve the abrasion resistance of alloy.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a 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 to refined paraffin-bas...
