摘要
硅灰石是一种新型工业矿物,具有白度高、折射率高、化学稳定性优异和独特的针状结构等特点,广泛应用在涂料、陶瓷、橡胶、塑料、造纸、绝缘、耐火材料等领域.但是,硅灰石颗粒表面呈现固有的亲水疏油性,造成和基体的相容性不佳,使其进一步的应用受到限制.详细介绍了硅灰石的不同改性方法及其优缺点,系统论述了硅灰石在塑料、陶瓷、造纸中的应用研究进展.
Abstract
Wollastonite is a new type of industrial mineral with high whiteness,high refractive index,excellent chemical stability,and unique needle like structure.It is widely used in coatings,ceramics,rubber,plastics,papermaking,insulation,refractory materials,and other fields.However,the surface of wollastonite particles exhibits inherent hydrophilicity and oleophobicity,resulting in poor compatibility with the matrix and limiting its further application.This article provides a detailed introduction to the different modification methods and their advantages and disadvantages of wollastonite,and systematically discusses the research progress of the application of wollastonite in plastics,ceramics,and papermaking.
