摘　　要：通过溶胶-凝胶原位合成法制备了一种新型纳米SiO2改性聚丙烯酸酯涂料,并对其各项性能(物化性能、机械性能、热性能)进行了分析和研究。结果发现,在聚丙烯酸酯涂料中添加纳米SiO2后,涂料乳液粒径增大,粒径分布变窄,有效改善了聚丙烯酸酯涂料的玻璃化温度,涂层的耐热性、硬度均得到了有效提升。A new type of polyacrylate coatings modified with nano-SiO2 by sol-gel synthesis was prepared.The properties such as physical,chemical,mechanical and thermal properties of the coatings were analyzed and studied.The result showed that the particle size of the coatings emulsion increased and the particle size distribution was narrowed after the addition of nano-SiO2,which effectively improved the glass transition temperature of the coatings.The heat resistance and hardness of the coating were improved effectively.
