Abstract: The infrared spectrum of imported ceramic dispergator products (PC67, Acumer 9300 and Acumer 9400) were detected and compared. The position and the intensity of the absorption peak in the infrared spectrum of the above three kinds of dispergator products were found to be the same as that of the sodium polyacrylate (PAAS 2000). It means that PC67, Acumer 9300 and Acumer 9400 are a kind of polycarboxylate substance, which is similar in structure to sodium polyacrylate. Using methacrylic acid (MAA) and sodium methallyl sulfonate (MAS) as raw materials, and sodium persulfate as initiator, and hydroquinone as terminating agent, a new type of high efficiency ceramic dispergator was prepared. The influences of reaction temperature (T), reaction time (t) and monomer molar ratio on the dispergation properties of the samples were investigated. The result shows that when T=80 ℃, t=3h and MAA:MAS=2:1, the prepared sample has good dispergation efficiency to ceramic slurry. Adaptability evaluation shows that, compared with PC67 and Acumer 9400, the sample prepared under those conditions has higher dispergation efficiency to building ceramic slurry, sanitary ceramic slurry and household ceramic slurry.
