Description
Technical field
The invention belongs to metallurgical technology field, more particularly to a kind of protective coating for surface of steel workpiece.
Background technology
During warm molding, the oxidation and decarbonization of iron and steel parts is inevitable problem.Iron and steel parts are due to exposed
Thermoforming, produces oxidation in atmosphere, causes steel surface to produce iron scale, form decarburized layer.Oxidation and decarbonization not only can
Reduce the performance indications of product, can also cause huge economic loss, therefore how process high-temperature steel anti-oxidation decarburizing problem
It is to ensure one of key factor of warm forming product quality and quality stability.
Content of the invention
The purpose of the present invention is exactly the defect in order to overcome above-mentioned prior art to exist, there is provided a kind of be used for iron and steel work
The protective coating on part surface, the paint ingredient that the present invention is provided can be under high temperature, in water evaporation in the presence of catalyst
After complete, one layer of uniform fine and close protective coating can be formed on surface, improve the structure and performance of surface of steel workpiece, so as to reach
To the effect of high temperature protection, purpose of the present invention is to be achieved through the following technical solutions：
A kind of protective coating for surface of steel workpiece, it is characterised in that composed of the following components by weight:
SiO2:45～50%
GeO2:8～13%
Al2O3：14～28%
Dispersant:0.02-0.2%
1.5 waterglass of modulus：5～10%
Catalyst:0.5～1%
Water：15-50%；
The catalyst is MnO2And MoS2Catalyst compounded.
Wherein, the dispersant is PVA.PVA is for GeO2、Al2O3、SiO2Disperse in water, have reasonable effect.
Wherein, MnO2And MoS2Ratio by weight is 1：1.Catalyst can reach preferably catalysis effect in this ratio
Really.
Wherein, GeO2、Al2O3、SiO2Weight ratio be 5：1：2.The GeO of such ratio2、Al2O3、SiO2Can be formed and more be caused
Close sealer, reaches more preferable protected effect.
Compared with prior art, the present invention has the advantage that as follows：
Under the high temperature conditions, in the presence of catalyst, a kind of de-oxidizing environment can be formed, under this de-oxidizing environment, this
Under the effective ingredient of coating after water evaporation is complete, one layer of uniform fine and close protective coating can be formed on surface, protect iron and steel work
Part is not oxidized.
