非异氰酸酯法大豆油基泡沫材料的研究

Study on soybean oil-based foaming materials prepared by non-isocyanate method

以丙烯酸酯化环氧化大豆油及改性偶氮二甲酰胺为起始原料,在自由基引发下模塑固化发泡制备出新型大豆油油基泡沫材料,该方法不依赖异氰酸酯原料。研究了发泡体系的热分解特性、泡沫材料的固化度、压缩性能及泡孔形态。

With acrylated epoxidized soybean oil （AESO） and modified azoformamide （MAC） as starting matefials,a new soybean oil-based foam was prepared successhtUy by radical mould curing. And this method doesn＇t need to introduce isocyanates. The heating decomposition of foaming system, curing degree, compression properties and cell morphology of formed foaming muterials were investigated by using soxhlet extractor, material test system and SEM.
