preparation example Construction

[0022] The invention provides a method for preparing ceramic powder, mainly by adjusting the formula of ceramic powder, reducing the clay content in the formula, and mixing additives for improving strength in the powder after powder making to prepare ceramic powder material. In the present invention, "clay" refers to clay materials for ceramics, such as washed ball clay, mixed clay, kaolin, bentonite (mainly composed of montmorillonite), attapulgite (variable composition) and the like.

[0023] Hereinafter, as an example, the preparation method of the ceramic powder of the present invention will be described.

[0024] Formulation of ceramic powder

[0025] The formula of ceramic powder contains clay and other commonly used ceramic raw materials, such as ceramic sand. In the present invention, the ceramic powder formula is adjusted to reduce the clay content. The clay content can be 0-10 wt%, preferably 0-8 wt%. From the perspective of saving clay resources, the less the cl...

Abstract

The invention relates to ceramic powder and a preparation method thereof. The preparation method comprises the steps that a ceramic raw material containing ceramic sand and clay is prepared into slurry, powder spraying is carried out, and first powder is obtained, wherein the clay content in the ceramic raw material is 0-10 wt%; an additive is evenly mixed with water to form mixed water, wherein the additive can be evenly dispersed in water and can improve the green body strength; the mixed water is atomized and evenly mixed with the first powder, and therefore the ceramic powder is obtained.

Description

technical field [0001] The invention belongs to the field of ceramic building materials, and in particular relates to a ceramic powder and a preparation method thereof. Background technique [0002] Porcelain clay is an essential part of ceramic formula. Its main function is to provide strength, viscosity and toughness for the formula to ensure that the formula will not rot during molding and processing. It is a non-renewable resource. After decades of use, it is good There are fewer and fewer ceramic clays, and the composition, whiteness, strength and other properties are getting worse and worse. The development of high-grade ceramics is more and more restricted, and the cost is getting higher and higher. At present, many additives can improve the strength of the green body very well, but they have a particularly large impact on the flow rate of the slurry. It is difficult to greatly change and reduce the amount of clay, and directly use the reinforcing agent to make powder...
