Abstract

The invention provides a dispersant for glaze. The glaze dispersing agent comprises the following raw materials in parts by mass: 60-80 parts of EDDHA, 2-5 parts of borax and a proper amount of water; the preparation method comprises the following steps: s1: the method comprises the following steps of (1) purchasing EDDHA and borax on the market, and weighing the EDDHA and the borax respectively for later use; s2: and (3) mixing the EDDHA and borax weighed in the S1 according to the weight ratio of 60-80: 2-5, adding a proper amount of water, mixing and stirring until uniform yellow viscous liquid is obtained, and thus completing the preparation of the dispersing agent for glaze. The dispersant for glaze provided by the invention has the advantages of simple preparation and stable molecular group, can dilute ceramic glaze slip, reduce the thixotropy of the ceramic glaze slip, solve the phenomena of jellied bean curd and egg bubble of the glaze slip, and can prevent the glaze slip from precipitating.

Description

Dispersing agent for glaze

Technical Field

The invention relates to the technical field of buildings, in particular to a dispersing agent for glaze.

Background

Ceramics are a generic term for ceramics and porcelain. The pottery was invented in the neolithic age about 8000 years ago. Common ceramic materials are clay, alumina, kaolin, and the like. Ceramic materials generally have a high hardness but a poor plasticity. Besides being used for tableware and decoration, ceramics play an important role in the development of science and technology. The ceramic raw material is extracted from a large amount of clay which is the original resource of the earth. The clay has toughness, can be plasticized when meeting water at normal temperature, can be slightly dried for carving, and can be completely dried for grinding; when the mixture is burnt to 700 ℃, the pottery can be made into pottery which can be filled with water; when the ceramic material is burnt to 1230 ℃, the ceramic material is vitrified, almost completely does not absorb water, and is high-temperature resistant and corrosion resistant.

In the ceramic production process, the thixotropy of the ceramic glaze slip is easy to be higher, and the phenomena of jellied bean curd and egg bubble of the glaze are easy to occur.

Therefore, there is a need to provide a novel dispersant for glaze to solve the above technical problems.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a dispersant for glaze, which is simple to prepare, has stable molecular groups, can dilute ceramic glaze slip, reduce the thixotropy of the ceramic glaze slip, solve the phenomena of jellied bean curd and egg bubble of the glaze slip and prevent the glaze slip from precipitating.

In order to solve the technical problems, the glaze dispersing agent provided by the invention comprises the following raw materials in parts by mass: 60-80 parts of EDDHA, 2-5 parts of borax and a proper amount of water;

the preparation method comprises the following steps:

s1: the method comprises the following steps of (1) purchasing EDDHA and borax on the market, and weighing the EDDHA and the borax respectively for later use;

s2: and (3) mixing the EDDHA and borax weighed in the S1 according to the weight ratio of 60-80: 2-5, adding a proper amount of water, mixing and stirring until uniform yellow viscous liquid is obtained, and thus completing the preparation of the dispersing agent for glaze.

Preferably, in S2, the mixing and stirring are performed at normal temperature, and the mixing and stirring time is controlled to be 2.5-5.5 h.

Compared with the related art, the dispersant for glaze provided by the invention has the following beneficial effects:

the invention provides a dispersant for glaze, which has stable molecular groups, can well dilute ceramic glaze slip to reduce the thixotropy of the ceramic glaze slip, can prevent the ceramic glaze slip from generating beancurd jelly and egg bubble, and can effectively prevent the ceramic glaze slip from precipitating.
