Ceramic underglaze color material and manufacturing method thereof

Abstract

The invention discloses a ceramic underglaze color material, which is composed of the following raw materials: polyacrylic acid resin, hydroxypropyl methylcellulose, N-ethyl urethane, oleic acid, Tween-80, isocyanate and succinic acid Sodium ester sulfonate, silicon dioxide, titanium dioxide, and deionized water. The underglaze color material is easy to load on the green body, has strong adhesion, uniform material color, and can quickly form a film with good peelability, which greatly reduces Difficulty in drawing, the development and use of this kind of underglaze color material solves the problems of uneven material color, inconsistent color tone, time-consuming carving and difficulties in industrial production when preparing art porcelain or porcelain board signboards and other porcelain works. It not only makes the picture of the fired porcelain fine and uniform, and has great artistic appreciation value, but also changes the traditional production method of porcelain, greatly simplifies the production process, and realizes the industrial production of works such as art porcelain and porcelain board signboards, filling the The gap in domestic technology has been filled.

Description

technical field [0001] The invention belongs to the technical field of ceramic manufacturing, and in particular relates to a ceramic underglaze color material and a manufacturing method thereof. Background technique [0002] Ceramics are utensils made of natural clay and various natural minerals through crushing, kneading, molding and calcination. In the process of ceramic preparation, the glaze color of the surface will undergo various chemical changes due to different firing temperatures. Thereby presenting different decoration styles. Among them, Jingdezhen's blue and white porcelain is one of the famous traditional Chinese porcelains. Its blue and white contrast, pleasant and interesting, crystal clear and bright, beautiful and timeless. [0003] Although the porcelain fired with underglaze color is bright in color, acid-resistant and wear-resistant, and can be maintained permanently, due to the inherent material properties of underglaze color, it is difficult to write ...

AI Technical Summary

Problems solved by technology

[0003] Although the porcelain fired with underglaze color is bright in color, acid-resistant and wear-resistant, and can be maintained permanently, due to the inherent material properties of underglaze color, it is difficult to write on larger porcelain works, such as some art porcelain. And the painting area is large, which can easily lead to uneven material color, and it is difficult to achieve the effect of fine picture and uniform color tone in the fired ceramics, so there are very few good products.

[0004] In addition, in the production of advertising signs such as porcelain boards, in addition to the above-mentioned uneven color of the material, the traditional method of engraving and then glazing and firing is also easy to cause the lower layer of material to be damaged and the upper layer of material to be suspended. Poor, time-consuming and labor-intensive, very unfavorable for industrial production

[0005] Therefore, the present invention intends to develop a kind of underglaze color material to solve the problem of uneven material color, non-uniform color tone, time-consuming carving and industrialized production of existing underglaze color materials in the preparation of porcelain works such as art porcelain or porcelain plate signboards. Difficulties and other problems, this kind of underglaze color material can change the production method of traditional art porcelain or porcelain plate signboard, not only simplify the production process, but also enable the industrial production of such porcelain, thus filling the domestic gap
