Abstract

The invention relates to a polymer debonding agent for ceramic slurry with good grinding aid effect. The invention adopts an unsaturated monomer containing two carboxyl groups as an anionic monomer, which has better anchoring effect on ceramic clay ions and better degumming effect. Better and more efficient. The molecular structure of the debonding agent of the present invention contains a large number of diethanolamine groups with good grinding effect and good degumming, which can effectively shorten the ball milling time and improve the degumming performance; it is synthesized by water-based free radical polymerization, and is simple to operate and easy to realize. Industrial production.

Description

technical field [0001] The invention belongs to the field of ceramic additives, and relates to a polymer debonding agent for ceramic slurry with good grinding aid effect and a preparation method thereof. Background technique [0002] The powerful slurry debonding agent for the preparation of ceramic raw materials is an indispensable additive for the processing of raw materials in ceramic slurry. It can significantly improve the fluidity of the slurry, reduce the moisture content, and reduce the energy consumption of spray granulation. It is a kind of It is an environmentally friendly product that enables ceramic production to achieve energy saving and green manufacturing. [0003] At present, the main product of strong slurry debonding agent is sodium tripolyphosphate, which is used alone or in combination. In recent years, due to the high price of yellow phosphorus, the price of phosphorus chemical products with yellow phosphorus as the main raw material has also increased....
