Problems solved by technology

These dispersants have disadvantages such as narrow dissolving range, easy solidification in a short time, poor adaptability and side effects.
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 provides a ceramic dispersing agent and a preparation method thereof. The preparation method comprises the following steps that 1, allylthiourea, cardanol sodium sulfonate, an acidity regulating agent and water are added into a reaction kettle, stirring is started, and heating is started to increase the temperature; 2, when the temperature is increased to 100 DEG C-120 DEG C, glyoxal starts to be dropwise added, and the dropwise adding time is 1-5 h; 3, cardanol epoxy propyl ether and prenol polyoxyethylene ether are added into the reaction kettle, and after the materials are stirred to be uniform, an initiator solution with the mass percent concentration of 1%-10% starts to be dropwise added, wherein the initiator solution is prepared from an initiator and part of water, the dropwise adding time is controlled to be 0.5-3 h, and the dropwise adding temperature is controlled to be 95 DEG C-120 DEG C; 4, after dropwise adding is completed, reacting continues to be conducted for 1-4 h by keeping the temperature, an alkalinity regulating agent is added for neutralization, after neutralization is completed, retaining water is added, cooling and discharging are conducted, and then the ceramic dispersing agent is obtained.

Description

technical field [0001] The invention belongs to the technical field of ceramic dispersant preparation, in particular to a ceramic dispersant and a preparation method thereof. Background technique [0002] Ceramic dispersant, also known as ceramic decoagulant, debonding agent, water reducer and diluent, etc., refers to a surface that can quickly wet the surface of solid particles and raise the energy barrier between solid particles to a high enough level. active agent. The main purpose is to keep the ceramic slurry with good fluidity within a certain period of time, that is, to reduce the surface energy of the particles, to reduce the interfacial tension between solid and liquid, to better and effectively infiltrate small solid particles, and to obtain high solid content and Good fluidity mud. In the preparation of special ceramic slurry, excellent dispersants can not only affect the surface charge of particles, but also change the chemical bond structure on the surface of ...
