Quenching agent used for machining abrasion-resistant alloy and preparing method thereof

Abstract

The invention discloses a quenching agent used for machining an abrasion-resistant alloy and a preparing method thereof. The quenching agent used for machining the abrasion-resistant alloy is composed of, by weight, 5-13 parts of polyvinyl alcohol, 2-7 parts of polyglycol laurate, 0.5-1.4 part of stearic acid, 7-10 parts of sodium sulfite, 2-4 parts of potassium trichlorine, 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; at first, stearic acid, corn starch and the palm oil are dissolved into polyvinyl alcohol to obtain mixed liquor, then water is added, the mixed liquor is transferred into a reaction kettle, after the reaction is finished, polyglycol laurate and 6-acetyl oxygen methyl-2,2-dimethyl-1,3-dioxolame-tert-butyl acetate are added in a cooling manner, and after stirring is carried out, the mixture stands; and then centrifuging is carried out, after centrifuging is carried out, supernatant liquor is taken, sodium sulfite, potassium trichlorine, D-aspartic acid and polyethylene glycol are added, after the mixture is stirred uniformly, temperature rising, temperature preserving and cooling are carried out, and sealing is carried out through paraffin oil, so that the quenching agent is obtained. The prepared quenching agent can improve abrasion resistance of the alloy greatly.

Description

technical field

[0001] The invention relates to the technical field of materials, in particular to a quenching agent for processing wear-resistant alloys and a preparation method thereof. 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 a...
