Description

一种隔热保温无氟聚氨酯泡沫材料
技术领域
本发明涉及一种泡沫，特别是一种隔热保温无氟聚氨酯泡沫材料。
背景技术
聚氨酯泡沫塑料是异氰酸酯和羟基化合物经聚合发泡制成，按其硬度可分为软质和硬质两类，其中软质为主要品种。一般来说，它具有极佳的弹性、柔软性、伸长率和压缩强度；化学稳定性好，耐许多溶剂和油类；耐磨性优良，较天然海绵大20倍；还有优良的加工性、绝热性、粘合性等性能，是一种性能优良的缓冲材料，但价格较高。聚氨酯泡沫塑料一般只用于高档精密仪器、贵重器械、高档工艺品等的缓冲包装或衬垫缓冲材料，也可制成精致的、保护性极好的包装容器；还可采用现场发泡对物品进行缓冲包装。
无氟聚氨酯硬质泡沫作为太阳能热水器中的保温材料，已被国内外业内人士普遍认可，它优异的绝热性能是任何一种高分子材料所不可比拟的，除此之外，它的抗压、防水、阻燃、耐酸碱腐蚀等性能也远比聚苯乙烯、岩棉、珍珠岩等其他保温材料好。

本发明所述隔热保温无氟聚氨酯泡沫材料，由以下具体步骤制备而成：
将A料各原料混合，在常温下研磨20-30分钟，得到浆料；再将B料加入A料中，200-300转/分搅拌30-45秒；浇注到模具中自由发泡，获得模坯；然后，连同模具一起将模坯送入隧道式烘箱中，分段升温：40-45℃下，反应15-25分钟；再在55-65℃下，反应10-15分钟；再在75-85℃下，反应5-10分钟；最后在90-100℃下熟化5-7小时。
