Description
Technical field
The invention belongs to metallurgical technology fields, more particularly to a kind of protective coating for surface of steel workpiece.
Background technology
Problem is inevitable in the oxidation and decarbonization for warming molding iron and steel parts in the process.Iron and steel parts are due to exposed
Thermoforming in air generates oxidation, and steel surface is caused to generate iron scale, form decarburized layer.Oxidation and decarbonization not only can
The performance indicator of product is reduced, can also cause huge economic loss, therefore how to handle high-temperature steel anti-oxidation decarburizing problem
It is one of key factor for ensureing warm forming product quality and quality stability.
Invention content
The purpose of the present invention is exactly to overcome the problems of the above-mentioned prior art, and what is provided is a kind of for steel work
The protective coating on part surface, paint ingredient provided by the invention can be under high temperatures, under the effect of the catalyst in water evaporation
After complete, one layer of uniform fine and close protective coating can be formed on surface, improves 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, which is characterized 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 MoS2It is catalyst compounded.
Wherein, the dispersant is PVA.PVA is for GeO2、Al2O3、SiO2Disperse in water, there is relatively good effect.
Wherein, MnO2And MoS2Ratio by weight is 1：1.Catalyst can reach preferably catalysis effect in this ratio
Fruit.
Wherein, GeO2、Al2O3、SiO2Weight ratio be 5：1：2.The GeO of ratio in this way2、Al2O3、SiO2It can be formed and more caused
Close sealer reaches better protecting effect.
Compared with prior art, the present invention has the advantage that as follows：
Under the high temperature conditions, under the effect of the catalyst, a kind of de-oxidizing environment can be formed, under this de-oxidizing environment, this
Under the active ingredient of coating after water evaporation is complete, one layer of uniform fine and close protective coating can be formed on surface, protects steel work
Part is not oxidized.
