| 摘 要： | 采用3种氨基硅烷偶联剂WD-50、WD-52和WD-57对SiC微粉进行表面改性,制备出高固相含量、低粘度的SiC料浆,并通过红外光谱分析了SiC微粉改性前后的表面特性.结果表明,采用偶联剂WD-52改性的SiC微粉固相体积含量达到54.5%、料浆稳定性显著提高且粘度降低,与偶联剂WD-50和WD-57相比,WD-52的改性效果最好.

| Abstract: | The surface modification of SiC powders with three kinds of aminoorganosilanes WD-50, WD-52 and WD-57 was carried out,and SiC slurry with high solid loading and low viscosity was prepared. Infrared fourier transform spectrometry was applied to analyze the surface characters of SiC powders. The results showed that the largest solid loading of SiC coated with WD-52 was raised up to 54. 5% and the stabilization of slurry also increased remarkably. At the same time , the viscosity of SiC slurry declined. Compared with WD-50 and WD-57,WD-52 was most effective for modification of SiC powders. |
