Problems solved by technology

When these dispersants are used in ceramic slurry, there are disadvantages such as large dosage and ineffective effect.
A small number of ceramic enterprises use organic dispersants and inorganic dispersants in combination. Although it can achieve certain effects, the dispersants developed are not universal and cannot be applied to various clay mineral raw materials, so it is difficult to popularize and use them.

Abstract

The invention discloses a composite ceramic dispersant and a preparation method, which belongs to the ceramic additive preparation filed. The composite ceramic dispersant is composed of 35-60% of sodium humate, 1-10% of polyacrylamide, 1-20% of sodium polyacrylat, 1-3% of potassium persulphate and the balance of water by weight percentage, and the preparation method comprises the following steps: preparing a mixing solution, performing a microwave radiation reaction, and grinding. The composite ceramic dispersant has the advantages of strong versatility, less amount and good effect, and the ceramic slurry and glaze slip can reach the required fluidity by the used composite ceramic dispersant under condition that water content is reduced as possible.

Description

technical field [0001] The invention relates to the field of ceramic additive manufacturing, in particular to a composite ceramic dispersant and a preparation method thereof. Background technique [0002] Ceramic slurry dispersant is a kind of ceramic additive, also known as deflocculant, degelling agent, deflocculant, dispersant, thinner. Its main function is to increase the ξ potential (zeta potential) of the system to improve the fluidity of the slurry. After use, the water content of the mud can be reduced as much as possible, and the required fluidity can be achieved, the water content of the billet can be reduced, the energy consumption of drying can be reduced, and the work efficiency can be improved. At the same time, it can reduce the porosity of ceramic products and improve the strength of ceramic products. In addition, the application of dispersant can also play a role of lubrication and grinding aid between the particles in the mud and improve the efficiency of ...
