Abstract
The invention relates to the technical field of automotive part machining, in particular to a preparation method of heat treatment fluid for heat treatment of an automobile brake disc. The preparation method comprises the steps that 15 parts of sodium polyphosphate and 20 parts of water are firstly added into a vessel and stirred for 10 minutes; then 1.5 parts of potassium carbonate is slowly added, stirring is carried out while adding is carried out, and stirring is carried out for 5 minutes after adding is finished; then 20 parts of polyvinyl acetate 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 minutes after adding is finished; then 0.5 part of anthra-glucoside is slowly added, stirring is carried out while adding is carried out, and stirring is carried out for 5 minutes after adding is finished; and finally 10 parts of ethylene glycol and 25 parts of water are slowly added, and stirring is carried out for 20 minutes. According to the preparation method of the heat treatment fluid, by means of step-by-step adding and reasonable selecting of feeding sequences, the dissolving property of all the substances can be improved, the probability of particle aggregation can be avoided, and therefore the heat treatment protection function of the heat treatment fluid is remarkably improved.
Description
Technical field
The present invention relates to vehicle component processing technique field, specifically relate to a kind of preparation method of automobile brake disc thermal treatment heat treatment solution.
Background technology
In prior art, brake flange is adding man-hour, and thermal treatment is absolutely necessary manufacturing procedure.In prior art, after brake flange carries out carburization step when thermal treatment, and do not add any heat treatment solution as strengthening agent, heat treatment efficiency can be caused so low, product of low quality, product surface causes the defects such as damage, easily occurs doing over again.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of preparation method of automobile brake disc thermal treatment heat treatment solution, for achieving the above object, present invention employs following technical scheme:
A preparation method for automobile brake disc thermal treatment heat treatment solution, first adds 15 parts of sodium polyphosphates and 20 parts of water in container, stirs 10 minutes; Then slowly add 1.5 parts of salt of wormwood, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 20 parts of polyvinyl acetate emulsions and 10 parts of water, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 0.5 part of anthra-glucoside, limit edged stirs, and stirs 5 minutes after interpolation; Finally slowly add 10 parts of ethylene glycol and 25 parts of water, stir 20 minutes.
Beneficial effect of the present invention shows:
1) formulating of recipe of the heat treatment solution, used in thermal treatment process is novel, rationally, particularly with the addition of a small amount of anthra-glucoside, can significantly improve heat treated processing efficiency, form excellent protective membrane, the quality of product is significantly improved.
2), the preparation method of heat treatment solution, by progressively adding and choose reasonable order of addition(of ingredients), the solubility property between each material can not only be improved, the possibility of particle agglomeration can also be avoided, the thermal treatment protection function of heat treatment solution is promoted significantly.
3), the preparation method of automobile brake disc thermal treatment heat treatment solution; operating procedure is succinct; by spraying the step of heat treatment solution after increase carburizing; and the formula of appropriate design heat treatment solution and preparation method; form excellent protective membrane; thus realize thoroughly being protected of brake flange surface, then improve the thermal effectiveness of brake flange and the quality of product.
Embodiment
Below with reference to embodiment, the present invention is described in detail.But; embodiment content is only citing made for the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
One, the composition of heat treatment solution
20 parts of polyvinyl acetate emulsions, 15 parts of sodium polyphosphates, 1.5 parts of salt of wormwood, 0.5 part of anthra-glucoside, 10 parts of ethylene glycol and 55 parts of water.
Two, the preparation method of heat treatment solution is:
First in container, add 15 parts of sodium polyphosphates and 20 parts of water, stir 10 minutes; Then slowly add 1.5 parts of salt of wormwood, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 20 parts of polyvinyl acetate emulsions and 10 parts of water, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 0.5 part of anthra-glucoside, limit edged stirs, and stirs 5 minutes after interpolation; Finally slowly add 10 parts of ethylene glycol and 25 parts of water, stir 20 minutes.
Three, the preparation method of automobile brake disc thermal treatment heat treatment solution, step is as follows:
Step 1., erasing brake flange surface greasy dirt, use ethanol clean 2 times, dry;
2., by brake flange step puts into cementing furnace carburizing, and treatment temp is 900 DEG C, and the treatment time is 2 hours;
Step 3., carburizing quenches after completing under pressure is 0.3MPa, to be cooledly makes its naturally cooling to when 50 DEG C;
Step 4., the heat treatment solution being heated to 40 DEG C is in advance sprayed into the surface of brake flange;
Step 5., put into dry 5 hours of constant temperature oven to form protective membrane on its surface, constant temperature in-furnace temperature is 100 DEG C.
