摘要
采用水基流延成型钙长石陶瓷基片坯体,研究分散剂、pH值、粘结剂及塑化剂对浆料流动性能的影响。实验结果表明:当浆料中固相含量为48vol%时,以聚丙烯酸胺为分散剂,浆料的pH值10,粘结剂含量为6.0wt%~8wt%时,增塑剂含量为4wt%~6wt%时,可以制备出稳定性良好、流动性适宜的钙长石流延浆料。通过SEM可以看出,高分子膜均匀包覆在钙长石颗粒表面,并且钙长石颗粒分布均匀,没有明显较大的孔隙。
The preparation of ceramic substrate by tape casting technique using aqueous slurries containing latex binder was studied.Effects of the solid phase content,dispersing agent,pH and plasticizer on the viscosities of the ceramic slurries of green tapes were discussed.The results showed that: when the solid content is 48vol%,pH of slurry about 10,latex binder 6wt%-8wt%,plasticizer 4wt%-6wt%,the prepared slurries had relatively low viscosity for casting.SEM photographs results showed polymeric membrane warpping up the anorthite particles and the homogenous distribution of anorthite particles without the obvious bigger pores.
