Macromolecule water reducing agent for reducing viscosity of clay slurry as well as preparation method and application thereof

Abstract

The invention discloses a macromolecule water reducing agent for reducing viscosity of clay slurry as well as a preparation method and an application thereof. The water reducing agent comprises a monomer, distilled water, inorganic chain transferring agent and initiator; the weight of the monomer accounts for 25 to 40 percent of the total weight of the monomer and distilled water; the monomer comprises crylic acid and sodium allysulfonate; the weight of crylic acid accounts for 70 to 85 percent of the total weight of the monomer, and the weight of sodium allysulfonate accounts for 13 to 35 percent of the total weight of the monomer. A hydrophilic group of the polymer monomer can be well adsorbed onto the surface of particles, hydrophilic side chains can be better strength in the mortar, the characteristics such as low mixing amount and high water reducing rate can be realized; moreover, the preparation method is simple to operate; the requirement on the device is simple in the production process, no after-treatment is needed, the energy consumption is low, and the environmental pollution is avoided. The dosage in the application process of the clay is small, the water reducing effect is good, the mobility of the clay slurry can be remarkably improved, and the viscosity of the clay slurry can be reduced; and the phenomenon that the clay slurry is settled in the addition range of the dosage of the additive can be avoided.

Description

technical field

[0001] The invention relates to the field of preparation of ceramic water reducers, in particular to a polymer water reducer for reducing the viscosity of clay slurry and its preparation and application. Background technique

[0002] With the development of society, people have higher and higher requirements for ceramic products. In the production and processing of ceramic products, in order to increase the fluidity of the slurry and reduce the viscosity of the slurry system, it is necessary to increase the amount of water added, and the addition of a large amount of water will cause poor thixotropy of the slurry system, prone to sedimentation, and also It will increase energy consumption in the drying process of ceramic products, resulting in increased production costs. The addition of ceramic additives can solve this problem well. Ceramic additives can reduce the viscosity of the clay slurry system, increase the fluidity of the system, and make the slurry...
