Abstract

The invention relates to an enamel glaze material for a steel plate. After the glaze material is calcinated, an enameled product has corrosion resistance, chemical resistance, weather resistance and decorative property, and the service life of the enamel can be prolonged. The technical problem to be solved is to provide the enamel glaze material. The enamel glaze material overcomes the defects that the conventional enamel glaze material is easy to deform and soften in high-temperature high-humidity environments. The enamel glaze material capable of resisting corrosion, softening and deformation is provided. The enamel glaze material comprises Ba2O3, Li2O, Na2O, MgO, Al2O3, SiO2, P2O5, SO3, K2O, CaO, TiO2, Cr2O3 and the like.

Description

A kind of frit for porcelain enamel
Technical field
The present invention relates to the frit for porcelain enamel that a kind of steel plate is used, this glaze can be given enamel and ceramic products solidity to corrosion, chemical resistant properties, weathering resistance and decorate properties after calcining, can improve the work-ing life of enamel.
Background technology
As everyone knows, japanning and enamel the porcelain method and can be given steel plate various performances, such as solidity to corrosion, chemical resistant properties, weathering resistance and ornamental, and can improve its work-ing life.And enamel that the porcelain steel plate compares with painted steel sheet be more excellent in many aspects, for example hardness, weathering resistance, cleaning Restoration, thermotolerance and flame retardant resistance, but also have corresponding problem, production cost costliness and enamel layer are easily peeled off.
At present, enamel the porcelain product and also is called rear coated article, by first process steel plate then enamel coating prepare.Compare its manufacturing cost with the precoating goods quite expensive, during the precoating goods, first continuous coating coiled material steel plate then carries out the making of sheet material after enamel porcelain and calcining.On the other hand, the film of painted steel sheet is poisonous to post-treatment to a certain extent.Therefore, by pre-coated steel plate, can manufacture slight fabricated product, reduce manufacturing cost, so be widely used painted steel sheet.In other words, enamel and painting products have limited the broadened application of enamel technical field at price differentials.But, the height had due to enamelware itself suppress contamination and by clean can excellent recovery chemical resistant properties, still be widely used in hospital.
For this reason, at present, in the urgent need to developing a kind of enamel, the porcelain steel plate, when this enameling sheet carries out bending machining after calcining enamel figure layer, still can keep enamel figure layer not peel off.
In order to solve the problem of above-mentioned existence, mainly for the formula of frit for porcelain enamel, taked improvement.But, do not have at present.
Summary of the invention

Contain ZnO in frit for porcelain enamel provided by the invention, because the existence of zinc in al-zn alloy coating can reduce the adhesion between coating and enamel layer, therefore add man-hour in the laggard line bend of enamelization when the gained enameling sheet, can strengthen the problem that enamel layer is peeled off.Due to zinc to oxidizing reaction have the height susceptibility, so its easily in the enamel step with enamel coating in inorganic oxide coating generation oxidizing reaction; The layer formed by oxidation can damage the adhesion between coating and enamel layer at its boundary.By interlayer middle layer between coating and uppermost enamel layer, can control the oxidizing reaction of these layers, just can suppress any excessive oxidation of al-zn alloy coating and enamel coating.
Exist and there is the zinc of sacrificing the solidity to corrosion effect in the alloy layer of contact steel plate, and exist enamel is adhered to excellent aluminium with high-content at alloy layer and enamel layer boundary, therefore obtain the enameling sheet of precoating type.The enameling sheet of this interpolation aluminium sesquioxide not only has excellent enamel adherence and suppresses the end face corrosion, and suppresses in addition the effect that bending machining is partly got rusty.
The Na contained in enamel provided by the invention 2o, Li 2o is the solubility promoter of frit for porcelain enamel, and it has expansion and burns till amplitude, affects glossiness and the weather resistance of enamel firing temperature, generation enamel.
Contain NiO, Co in frit for porcelain enamel provided by the invention 3o 4, MnO, P 2o 5, these compounds belong to adhesive agent, have and suppress reacting of al-zn alloy coating and enamel layer.
The CaO contained in frit for porcelain enamel provided by the invention is the raw material of well fluxing, and it can reduce the viscosity of melts in enamel significantly.
The BaO contained in frit for porcelain enamel provided by the invention is the component that impact generates chemical durability, mechanical property and the thermal expansivity of enamel layer.
SiO in frit for porcelain enamel of the present invention 2that impact generates the chemical durability of enamel layer and the component of mechanical property.
The CaO contained in frit for porcelain enamel provided by the invention and TiO 2use together the effect that plays inferior light.
The proportioning the present invention relates to and percentage composition thereof are all by percentage to the quality.
In sum, the present invention has and compares the existing more resistant to elevated temperatures characteristic of enameling sheet, has and shows, high temperature resistant, in long-time hot environment, the softening time of surperficial enamel glaze is long, corrosion resistance nature is good simultaneously, and glaze is in hot environment, can keep for a long time corrosion resistant characteristic.
