Description

PMMA包裹NaHCO3乙醇溶液的热膨胀微球及其制备方法
技术领域
本发明属于高分子材料技术领域，具体涉及一种PMMA包裹NaHCO3乙醇溶液的热膨胀微球及其制备方法。
背景技术
热膨胀微球具有良好的物理化学性能。热膨胀微球制备的发泡材料其强度、力学等性能比单纯的气体发泡有很大的优势，发泡材料泡孔均匀、细腻，力学性能良好，热膨胀微球不仅增加了材料的比体积，而且还有质轻、绝缘性、消除噪音等优点以及改善材料折光性和透明度等光学性能的特性。被广泛应用于建筑、汽车、飞机材料和特种材料等行业。
目前，现有技术中，如专利CN104140549.A的发明专利，涉及低温热膨胀微球。该发明由不饱和烯属类单体聚合得到的外壳包裹惰性碳氢化合物，所述不饱和烯属类单体由丙烯腈、丙烯酸酯类和乙酸乙烯酯单体组成，但是芯材选用烷烃类，芯材为低沸点、易挥发且分子量大于26的低分子烷烃，目前应用最多的是石油醚、异辛烷、异戊烷。制备方法为悬浮聚合法。由于低沸点的烷烃在聚合反应过程中需要高压以减少其挥发，这不仅增加了实验成本，污染环境，也存在很大的安全隐患。且悬浮聚合方法试验周期长，操作复杂。
