2.1 材料
Nano-CaCO3 particles (D50: 30−70 nm by TEM (Fig. 1) and BET: ca.17m2•g-1) were supplied by Shanghai Zhuoyue Nanotech Corporation. Methyl methacrylate (MMA, Shanghai Lingfeng Chemicals) was purified by distillation under reduced pressure; potassium persulphate (K2S2O8, initiator, Shanghai Lingfeng Chemicals) was of chemical grade. Silane coupling agent A174 (γ-methacryloxypropyltrimethoxysilane) was purchased from Shanghai Yaohua Factory. Polyvinylchloride (PVC, WS-1000S) was supplied by Shanghai Chlor-Alkali Chemical Co., Ltd.
纳米碳酸钙粒子(中值粒径:透视电子显微镜测定为30-70纳米 (图1)且用BET比表面积仪测定Ca的比表面积为17 m²/g)由上海Zhuoyue 纳米技术公司提供。MMA (上海Lingfeng化工生产)用减压蒸馏法提纯;过硫酸钾(K2S2O8,引发剂,上海Lingfeng 化工)是化学级别的。硅烷偶联剂A174(γ-(甲基丙烯酰氧)丙基三甲氧基硅烷)从上海Yaohua 厂采购。聚氯乙烯(PVC,WS-1000S)由上海氯碱化工股份有限公司供应。

2.2 PMMA emulsion polymerization on CaCO3 nanoparticles
2.2.1 Surface silanation of nano-CaCO3 particles
The nano-CaCO3 particles were homogeneously dispersed in ethanol (solid content 20%) by a sonication dispersion equipment. The slurry was then heated to 80°C with stirring, and the silane coupling agent A174 (5%, calculated based on the weight of nano-CaCO3 particles) was added into the slurry. After the slurry was stirred for 120 min at 80°C, it was filtered and the filter cake was then dried at 120°C in low vacuum for 120 min to obtain silanated CaCO3 powders.
2.2 碳酸钙纳米粒子上的PMMA乳液聚合作用
2.2.1纳米碳酸钙粒子的表面硅烷化处理
纳米碳酸钙粒子通过声波降解扩散装置均匀散布在乙醇(固含量为20%)中。边搅动边加热料浆至80°C,然后在料浆中加入硅烷偶联剂A174(5%,基于纳米碳酸钙粒子的重量来计算)。在80°C温度下搅动120分钟后,过滤料浆,将滤饼在120°C低真空环境中烘干120分钟,从而得到硅烷化的碳酸钙粉末。
