高亮白抗紫外抗老化功能性填料纳米碳酸钙及其制备方法和用途
摘要：
本发明公开了一种高亮白抗紫外抗老化功能性填料纳米碳酸钙，在制备工艺中通过对反应体系浓度、终止pH值、反应温度、分散剂的配方及包覆剂的选择各项指标进行精准控制，得到粒径为80nm‑200nm、白度达到92以上、氧化锌包覆量达到4%、无团聚现象、具有抗紫外抗老化的高性能多用途纳米碳酸钙，所得产品能够在橡胶、硅胶、塑料、造纸领域作为填料增加产品的抗氧化抗紫外线性能及亮洁度。
摘要（英）：

The invention discloses high bright and white anti-ultraviolet anti-aging functional filler nanometer calcium carbonate. Through the accurate control on various indexes including a reaction system concentration, a stop pH value, reaction temperature, a formula of a dispersing agent and the selection of a coating agent, the anti-ultraviolet anti-aging high-performance multipurpose nanometer calcium carbonate with the grain size being 80 to 200nm, the whiteness reaching greater than 92, the zinc oxide covering amount reaching 4 percent and without agglomeration is obtained, and an obtained product can serve as a filler in the fields of rubber, silica gel, plastic and paper making to improve the antioxidant and anti-ultraviolet properties and the brightness of products.
