Description

一种凹土改性的双马来聚酰亚胺-碳酸钙填料
技术领域
本发明涉及一种碳酸钙填料，具体涉及一种凹土改性的双马来聚酰亚胺-碳酸钙填料。
背景技术
碳酸钙是一类重要的功能性无机填料，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，由于碳酸钙为亲水性化合物，导致在实际应用中存在与高聚物相容性不足，分散性差等缺陷，不能达到满意的填充补强效果，因此需要对碳酸钙进行改性处理，以提高其在各类材料中分散性和相容性，以达到改善产品性能的功效。
凹土即凹凸棒粘土（Attapulgite Clay）的简称。是一种稀有非金属矿产资源，它是一种层链状结构的含水富镁铝硅酸盐粘土矿物。凹凸棒石作为一维天然纳米结构材料，可有效改善高分子材料的综合性能，相关复合研究为凹土应用开发研究的热点，也是凹土产业高值化的重要增长点。
专利CN1400167A公开的一种表面改性纳米碳酸钙的制备方法，采用饱和脂肪酸钠盐作为表面处理剂；专利CN1654551A公开了一种纳米碳酸钙的改性方法，采用双子星表面活性剂二磷酸酯盐作为改性剂；都是在已碳酸化完成的碳酸钙乳液中加入表面处理剂在一定温度、浓度和比例下液相活化反应而得。此种方法得到的碳酸钙填料虽然分散性得到了提高，但是应用性能任然没得到改善。
