Description

A kind of preparation of low-alloy super-strength steel heat treatment protective coating
Technical field
Field is protected in metal heat treatmet the present invention relates to low-alloy super-strength steel, at a kind of metal fever Reason protective coating.
Background technology
The heat treatment of metal material is a very important process in metal machinery manufacture process, it is directly affected The final mass and service life of metal parts.Low-alloy super-strength steel D6AC is a kind of special steel material, its is heat treated Cheng Zhong, maximum temperature is up to 950 DEG C, more than two hours of time.In heat treatment process, it is desirable to metal base without obvious oxidation and Decarburization.After Overheating Treatment, the mechanical performance such as tensile strength, yield strength, elongation percentage cannot all decline metal.Involved by the present invention And Protective paint for heat treatment of metal, can effectively prevent possibility of the low-alloy super-strength steel D6AC in heat treatment process from going out Existing oxidation and decarbonization situation, while the mechanical performance of metal is not in decline.Other metal heat treatmets compared in the market are protected Coating is protected, its thickness of constructing is thinner, and less than 80um, when being quenched in heat treatment process, paint film Automatic-falling area is more than 95%.City Field similar product, construction requirement minimum thickness 100um, pull-away area are more than 90%.
The content of the invention
For the heat treatment requirements of low-alloy super-strength steel D6AC, the present inventor have developed at a kind of metal fever Manage protective coating.During metal heat treatmet, oxygen of the low-alloy super-strength steel D6AC in hot environment can be effectively prevented Change decarburization and the decline of mechanical performance.The principle of the present invention is, is to apply first with the rise of furnace temperature in heat treatment process The fast decoupled of contained resin and auxiliary agent among material, then be the high-temperature fusion of frit powder and color stuffing, formed one layer it is fine and close Inorganic protective film, realizes the high-temperature oxidation resistant protection to base material.In quenching, the spy that film itself coefficient of expansion is larger is utilized Property, realize that the quick of film completely comes off.
The low-alloy super-strength steel D6AC heat treatment protective coatings are by acrylic resin, dispersant, polyamide wax Powder, frit powder, mica iron oxide red, blanc fixe, kaolin, talcum powder, chrome oxide green, solvent composition.
Based on the gross mass of coating, the content of each component is:
The sum of each component content is 100%.
The acrylic resin is alcohol-soluble acrylic resin.
The dispersant is at least one of BYK-182, BYK-184.
The levelling agent is at least one of BYK-346, BYK-320.
The frit powder A is about 400 DEG C of beginning fusing point, and temperature in use is 450 DEG C~650 DEG C of frit, through ball mill grinding It is 800 mesh powders to fineness.
The frit powder B is about 650 DEG C of beginning fusing point, and temperature in use is 650 DEG C~850 DEG C of frit, through ball mill grinding It is 800 mesh powders to fineness.
About 950 DEG C of the frit powder C beginnings fusing point, temperature in use are 900 DEG C~1200 DEG C of frit, through ball mill grinding extremely Fineness is 800 mesh powders.
The solvent 1,2 is the industrial goods ethanol or absolute ethyl alcohol of content 95%.
The solvent 3 is the isopropanol of industrial goods.
The preparation method of low-alloy super-strength steel D6AC heat treatment protective coatings of the present invention, is formulated as described above Stock, its preparation process are:
Acrylic resin and solvent 1 are added in container, dispersant and stream are added under being 100~150 revs/min in rotating speed Flat agent, is stirred 10~15 minutes, adds polyamide wax powder, and rise rotating speed stirs 10~15 minutes to 200~300 revs/min, then Added under being 100~150 revs/min in rotating speed frit powder A, frit powder B, frit powder C, mica iron oxide red, blanc fixe, After kaolin, talcum powder, chrome oxide green stir 20~30 minutes, fineness is ground to less than 50 microns through being sanded, with solvent 2 and molten The viscosity that agent 3 adjusts coating is less than 25 seconds (applying -1 glass).Up to low-alloy super-strength steel D6AC heat treatment protective coatings.
In use, first low-alloy super-strength steel D6AC is stirred evenly with heat treatment protective coating, it is ensured that do not have There is layering and sink to the bottom, it is 60~80 microns which, which requires the thickness of application, can divide 2~3 times and reach required application thickness.
The present invention has the advantages that compared with prior art:
(1) in the case where film thickness is less than 80 microns, there is good heat treatment protecting effect to special steel D6AC.City Field similar product will reach preferable protecting effect, and film thickness is thicker.
(2) in quenching process, for paint film from the area that comes off more than 95%, market similar product, the area that comes off certainly is more than 90%.
