Problems solved by technology

[0003] However, there are some problems in the production and use of enamelled steel plates at present: first, the production cost of enamelled steel plates is relatively high, and the production efficiency is low. Shape, and then enamelled to prepare enameled steel plate for application, this method not only has high production costs, high labor costs, but also a great waste of energy and raw materials; secondly, the current enameled steel plate has poor processability, and the enamel layer is sticky Adhesion is not good enough, and the enamel layer cracks and falls off during processing; again, the preparation temperature of enamel glaze and the firing temperature of enamel are relatively high, which is a great waste of energy. There are also certain restrictions
The enamel steel plate can be bent, and the enamel layer will not peel off after bending, but it will produce certain cracks, which will extend to the bottom of the enamel layer and the coating, so that the middle layer and the coating are cracked, and the base steel plate is exposed. The glaze and its enamelled steel sheet described in the patent are not suitable for continuous production of enamelled coils

[0044] The preparation method of the enamel glaze for the above-mentioned enamel coil comprises the following steps:

[0045] 1) Selection of raw materials. According to the purpose of the present invention, the raw materials of the glaze can be directly mixed with the required oxides or fired from the mixture, which is not limited. That is to say, the required raw materials can be directly selected from industrially pure grades, or can be extracted from mineral raw materials. Optional raw materials include clay, quartz sand, barium carbonate, cobalt oxide, boron oxide, copper oxide, aluminum oxide, magnesium oxide, antimony trioxide, nickel oxide, iron oxide, phosphorus pentoxide, potassium feldspar, boric acid, Potassium carbonate, barium carbonate, potassium oxide, sodium nitrate, ammonium hydrogen phosphate, potassium hydrogen phosphate, etc.;

[0046] 2) Weigh the required raw materials according to the above ratio and fully pulverize and mix them, and pass through at le...

Abstract

The invention relates to an enamel glaze for an enamel rolled plate, a preparation method of the enamel glaze as well as a method for preparing the enamel rolled plate by the enamel glaze. The preparation method of the enamel glaze is characterized in that the method comprises the steps as follows: 1) selecting materials, weighing needed materials by a certain proportion and sufficiently grinding and mixing the weighed materials; 2) heating and baking the mixture, baking the mixture for at least 30 minutes and at most 2 hours at the temperature of 700-100 DEG C so as to sufficiently melt the mixture of the materials; 3) conducting quenching, putting the sufficiently-melted mixture in water to quench and then forming smashed glaze after quenching; and 4) grinding and refining the smashed glaze to prepare the enamel glaze. An enamel steel plate prepared by coating the prepared enamel glaze on a steel plate has excellent resistance to acid-base corrosion and is braked at the low temperature of 500-600 DEG C; the enamel layer neither cracks nor peels in bending, thereby having excellent processability; the enamel layer has strong adhesion and the radius of curvature in bending can achieve the minimum of 250mm; and the roll-to-roll continuous production of the enamel steel plate can be realized.

Description

technical field [0001] The invention relates to an enamel glaze for enamel coils and a preparation method thereof, belonging to the field of enamel glazes and its preparation, in particular to an enamel glaze for enamel coils, a preparation method thereof and a method for preparing enamel coils using the glaze. Background technique [0002] The development of enamel has a history of thousands of years, and the initial enamel was used by a few people as handicrafts. With the continuous development of technology, a new era of enamel development has been created. The promotion and application of various metal materials and enamel has also accelerated the development of the enamel industry. The emergence of enamel has greatly improved the service life of metal materials, expanded its scope of use, and endowed metal materials with a series of excellent properties, such as corrosion resistance, weather resistance, decoration, heat resistance, flame retardancy, etc. . Enamel stee...
