Problems solved by technology

[0003] The existing porcelain plate painting production process has been in a state of backward technology, complicated process and fragile for many years. It is generally made of ordinary ceramic plates. The amount of mineral raw materials and industrial water used in ordinary ceramic plates is large, and the ceramic plates are elastic. , toughness and strength are relatively low
At the same time, in the process of making porcelain plate paintings, it is necessary to continuously use high temperature to fire the ceramic plate. High temperature consumes a lot of energy and makes the color of the porcelain plate not guaranteed, which affects production efficiency.
For example, the invention patent with the application publication number CN104085243A, which is a preparation method of porcelain plate painting, and the invention patent with the application publication number CN108467261A, which is a kind of artistic porcelain plate painting and its production process, all use clay During the preparation process, glazes of various colors are painted on the fired plain porcelain plate to form a picture frame, and then a layer of transparent glaze is applied on the surface of the plain porcelain plate, and finally it is put into the kiln for a second time. It can be formed only by firing at high temperature. It has no water absorption, and the production process is multiple and complicated.
In addition, the existing unglazed porcelain plate is brittle and the finished product is fragile; and the background color is yellowish, and the yield rate is not high

Abstract

The invention relates to the technical field of ceramics, particularly to porcelain clay, and a porcelain and a preparation method thereof. The porcelain clay is composed of silicon oxide, aluminum oxide and calcium carbonate. The preparation method comprises the following steps: 1, preparing a mixture of silicon dioxide, aluminum oxide and calcium carbonate; 2, mixing and grinding green body rawmaterials into powder, adding water, and aging to obtain a pasty mixture; 3, filtering the aged pasty mixture to obtain a green body pug, treating wet green body pug byapplying a ceramic forming process, and carrying out blank trimming, and airing or drying to obtain a ceramic green body; and 4, carrying out high-temperature firing on the aired green body to obtain the porcelain. According to theinvention, the porcelain is obtained through one-time high-temperature sintering, the manufacturing process of the porcelain is simple, and the porcelain surface produced through the method has fine frosted texture and has the advantages of being high in whiteness, extremely easy to color, free of secondary sintering after glazing and coloring, high in toughness, resistant to abrasion and good inwater permeability.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a china clay, porcelain and a preparation method thereof. Background technique [0002] China's porcelain production has a long history and various varieties. Porcelain plate painting, as a kind of porcelain products, refers to a kind of flat ceramic handicraft made by using special chemical pigments on fired plain ceramic plates, glazing, and then firing twice at high temperature. Porcelain plate painting can be mounted , or embedded in a screen for ornamental purposes. Compared with paper paintings and silk paintings, porcelain plate paintings have stable physical and chemical properties. They are not afraid of moisture and mildew. Their colors will remain bright for decades and have great High application, collection and ornamental value, deeply loved by people. [0003] The existing porcelain plate painting production process has been in a state of backward technology, com...
