2004/03/22
一種製備陶瓷粉末懸浮液的方法,係提供一分散劑,而分散劑的構造式如下 其中D是H或COOR1、R1可為H、碳數由1到10的烷基或環形脂肪族基或芳香族基,以及陽離子鹽基。R2可為碳數由1至10的烷基、環形脂肪族基或芳香族基,而R3是H或CH3、Z是O或NH、A是COO,SO3或其酸根形態,a為1到5000之整數,以及p、q為1到10之整數。接著,將分散劑溶於一溶劑中,再將陶瓷粉末加入已有分散劑的溶劑中。 A method for preparing a ceramic powder suspension is disclosed. A dispersant having a following structural formula is provided: wherein D is H or COOR.sub.1; R.sub.1 is a hydrogen atom, or an alkyl group, a cyclic aliphatic group, an aryl group, having 1 to 10 carbon atoms, or a cationic salt group; R.sub.2 is an alkyl group having 1 to 10 carbon atoms, a cyclic aliphatic having 1 to 10 carbon atoms or an aryl group having 1 to 10 carbon atoms; R.sub.3 is a hydrogen atom or a methyl group; Z is an oxygen atom or an NH group; A is --COO --SO.sub.3 or an acid form; a is an integer between 1 to 5000; and p and q are integers between 1 to 10. The dispersant is dissolved in a solvent. Ceramic powder is further added into the solvent with the dispersant.
