Polycarboxylic acid type ceramic dispersant as well as preparation method and application thereof
The invention belongs to the technical field of preparation of ceramic dispersants, and discloses a polycarboxylic acid type ceramic dispersant as well as a preparation method and application thereof. The preparation method comprises the steps of mixing 3-dimethyl(methacryloyloxyethyl) ammonium propane sulfonate, acrylic acid, a neutralizing agent and a chain transfer agent by agitating; heating to reach a temperature of 60 to 90 DEG C to obtain a mixed solution I; dropwise adding an initiator solution into the mixed solution I; heating to obtain a mixed solution II; adding a chain terminator into the mixed solution II; stopping heating; cooling by agitating until reaching room temperature so as to obtain the polycarboxylic acid type ceramic dispersant. The polycarboxylic acid type ceramic dispersant has an obvious reinforcement effect for ceramic biscuits; with the adoption of the polycarboxylic acid type ceramic dispersant, the application of a reinforcing agent can be decreased; quaternary ammonium cations are introduced to a main chain of polycarboxylic acid, so that the hydration capacity and heat stability of the polycarboxylic acid type dispersant can be improved; the preparation method has the advantages that the reaction is carried out under mild conditions, the synthesis process is simple, and the industrial production is easily carried out.
