塑料制品专用金红石型钛白粉的改性技术

Modification Technology of Rutile Titanium Dioxides for Plastic Products

在塑料制品生产过程中添加金红石型钛白粉可以提升塑料制品的耐光性、耐热性和耐候性,改善塑料制品的物理性能,有效延长塑料制品的使用寿命。未经改性的钛白粉在生产、运输、存储过程中容易吸水,限制了钛白粉的应用范围和功能,文章综述了钛白粉的改性技术,为其在塑料领域的应用打开思路。

Rutile titanium dioxides can be added in the production process of plastic products not only to improve the light resistance,heat resistance and weather resistance,and the physical properties of plastic products,but to effectively extend the service life of plastic products.Unmodified titanium dioxides are so easy to absorb water in the process of production,transportation and storage,which limits its application scope and performance.This paper summarizes the modification technology of titanium dioxides,and provides reference for its application in the field of plastics.
