背景技术
发泡材料由于内部含有大量气泡，与传统的材料相比，不仅质轻、省料,而且能吸收冲击载荷,具有优良的缓冲性能而被广泛应用于各种的产品的防护和包装中。目前，常见的发泡材料有聚氯乙烯（PVC）、聚氨酷（PU）、聚烯烃（PE、PP）、乙烯一醋酸乙烯酷(EVA)、热塑性橡胶(TPR)等，其中PVC发泡材料因其具有良好的力学性能和粘结性、加工方便、成本低廉等优点，在实际的生产生活中具有重要的意义。
尤其是在人造革领域，由于PVC具有制品强度高，加工容易，成本低廉等优点，PVC成为人造革的最主要原来之一。在PVC人造革生产过程中，需要发泡形成微孔结构，赋予其成品质轻、手感丰满、柔软的优点。然后，
目前PVC采用的发泡剂一般为偶氮二甲酰胺类发泡剂，在发泡过程中产生较大的气味，而且这种气味会残留在制品中，直接影响了PVC人造革的应用，对人类的生活健康造成了一定程度的威胁。因此，寻找一种环保的PVC发泡材料是当前亟待解决的问题。
