example 1

[0038] Add 145kg of allyl alcohol polyoxyethylene ether with a molecular weight of 2000 and 120kg of water into the reactor, heat to 30°C and stir to completely dissolve the allyl alcohol polyoxyethylene ether, then add 1.2kg of hydrogen peroxide (mass concentration 35%).

[0039] Add 18kg of acrylic acid and 20kg of deionized water into No. 1 high-level tank, add 0.2kg of ascorbic acid, 1.0kg of isopropanol and 38kg of deionized water into No. 2 high-level tank, and then slowly add the solutions in the two high-level tanks to the reaction kettle at the same time. The liquid in the No. 1 high-level tank is added in about 3 hours, and the liquid in the No. 2 high-level tank is added in about 3.5 hours. Add 80kg of acrylic acid to No. 3 head tank, add 0.5 kg of ascorbic acid and 80 kg of deionized water to No. 4 head tank. After the liquid was added to the No. 2 head tank, the constant temperature stirring reaction was continued for 1.0 hour to obtain an intermediate polymer. T...

Abstract

The invention relates to a polymer water reducing agent used for ceramic machining and a synthetic method of the polymer water reducing agent used for ceramic machining. The method is characterized in that firstly, macromolecule unsaturated monomers containing polyether long chains are copolymerized under the action of radical initiators to form intermediate state polymers, then the other part of unsaturated acid and radical imitators are added, copolymerization is performed continuously, and finally neutralizing is performed to obtain the polymer water reducing agent. The polymer water reducing agent is high in water-reducing rate and dispersing and plasticizing capacity and can be applied to the technological processes of powder making, slip casting and others in the ceramic industry and dispersing pigment and fillings in coating and ink.

Description

technical field [0001] The invention belongs to the field of ceramic processing aids, in particular to a polymer water reducer for ceramic processing and a synthesis method thereof. Background technique [0002] Ceramics is a resource industry. my country consumes a large amount of non-renewable mineral resources such as clay and gypsum every year, resulting in a significant reduction in the stock of many high-quality clays, and some areas have been exhausted. Moreover, ceramics is also an industry with high energy consumption. Energy consumption accounts for one-third of the production cost of ceramics, and a large amount of electricity and gas are consumed every year. Therefore, reducing energy consumption and improving resource utilization is an urgent problem to be solved in the ceramic industry. [0003] As the most widely used additive in ceramic processing, water reducing agent can not only reduce the cost, but also further improve the performance of ceramic products...
