Description

一种耐磨性复合碳酸钙及其制备方法
技术领域
本发明涉及工业填料领域，尤其涉及一种耐磨性复合碳酸钙及其制备方法。
背景技术
碳酸钙是一种无机化合物，CaCO3俗称：灰石、石灰石、石粉、大理石等，是由钙离子和碳酸根离子结合生成的，是一类重要的功能性无机填料，工业上用途甚广，具有价格低廉、储量丰富、性能稳定、易加工、无毒等优点，能够显著的改善材料的加工性能、物理性能以及降低生产成本等等，广泛应用于塑料、橡胶、涂料、造纸等领域。
在碳酸钙的应用领域中，大多产品属于聚合物的范畴，然而，碳酸钙粒子表面分布有强亲水性的羟基，表现为碱性，和有机高聚物基质材料的界面性质不同，相容性差，难以在基质材料中分散均匀以及和基质材料形成强的结合力，造成两材料之间的界面缺陷，使复合材料某些力学性能下降。因此需要改变传统碳酸钙产品的性能，改善其应用性能以满足新材料、新技术发展的需要，是碳酸钙工业急需解决的问题。
