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 naphthalene-based ceramic dispersant and a preparation method thereof. The steps are as follows: (1) Add glucose allylamide, methylnaphthalenesulfonic acid, acid regulator and water to a reaction kettle, start stirring, and start Heating to raise the temperature; (2) When the temperature rises to 95-120°C, start to add formaldehyde dropwise for 0.5-5 hours; (3) Add 3-ureapropyltrimethoxysilane, cyclic Oxygen compound, after being stirred evenly, start to drop an initiator solution with a mass percent concentration of 1-10%, which is prepared from the initiator and part of the water; the dropping time is controlled at 0.5-4 hours , the temperature is controlled at 90 to 120°C during the dropwise addition; (4) after the dropwise addition, keep the temperature and continue the reaction for 1 to 4 hours, add an alkaline regulator for neutralization, and cool down and discharge the material after the neutralization is completed, to obtain the naphthalene Department of ceramic dispersant.

Description

technical field [0001] The invention belongs to the technical field of preparation of ceramic dispersants, in particular to a naphthalene-based 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 struct...
