Embodiment Construction

[0009] The present invention will be described in more detail below in conjunction with examples. However, the content of the embodiments is only an example and description of the present invention. Those skilled in the art can make various modifications or supplements to the described specific embodiments or replace them in similar ways, as long as they do not deviate from the principles of the invention. Conception or beyond the scope defined in the claims shall belong to the protection scope of the present invention.

[0010] 1. Composition of heat treatment agent

[0011] Made from 12 parts of acrylate emulsion, 10 parts of sodium laureth sulfate, 0.5 parts of potassium carbonate, 0.5 parts of flavonoid glycosides, 10 parts of cyclohexane and 40 parts of water.

[0012] Two, the preparation method of heat treatment agent is:

[0013] First add 10 parts of sodium lauryl ether sulfate and 20 parts of water into the container, and stir for 5 minutes; then slowly add 0.5 par...

Abstract

The invention relates to the technical field of vehicle part machining, in particular to a preparing method for a heat treating agent for heat treatment of a speed changing box shell. Firstly, 10 parts of sodium laureth sulfate and 20 parts of water are added into a container to be stirred for 5 min; then 0.5 part of potassium carbonate is slowly added, stirring is carried out while adding is carried out, and stirring is carried out for 5 min after adding is completed; then 12 parts of acrylate emulsion and 10 parts of water are slowly added, stirring is carried out while adding is carried out, and stirring is carried out for 5 min after adding is completed; 0.5 part of flavonoid glycoside is slowly added, stirring is carried out while adding is carried out, and stirring is carried out for 5 min after adding is completed; and finally, 10 parts of cyclohexane and 10 parts of water are slowly added, and stirring is carried out for 20 min. According to the preparing method for the heat treating agent, through gradual adding and reasonable selection of the feeding sequence, the dissolving property of all substances can be improved, the possibility of particle aggregation can be avoided, and the heat treatment protection function of the heat treating agent is obviously improved.

Description

technical field [0001] The invention relates to the technical field of vehicle parts processing, in particular to a preparation method of a heat treatment agent for heat treatment of a gearbox case. Background technique [0002] Usually, heat treatment is an essential process when the gearbox housing is processed. In the prior art, the gearbox housing is directly carburized during heat treatment without adding any heat treatment agent as a protective agent, which will result in low heat treatment efficiency, low product quality, and damage to the product surface. Contents of the invention [0003] In view of the technical problems existing in the prior art, the object of the present invention is to provide a preparation method of a heat treatment agent for the heat treatment of the gearbox housing. In order to achieve the above object, the present invention adopts the following technical solutions: [0004] A kind of preparation method of heat treatment agent for heat tre...
