Description
技术领域
本发明属于阻燃材料的制备技术领域,特别涉及一种用于冰箱发泡层的阻燃硬质聚氨酯。
背景技术
现在随着人们生活水平的提高,家电产品已经成为生活中必不可少的组成部分。电冰箱作为常见的家用电器之一已经进入千家万户,目前我国已经成为世界最大的冰箱生产国,中国城市家庭中冰箱的普及率已经超过90%,而且这个数目仍在增加,我国是目前世界上冰箱生产和消费最大的国家,各大冰箱生产企业在中国市场的竞争逐渐进入白热化阶段,而节能、环保、降成本、简化工艺则是是冰箱发展的主要路线。
冰箱要节能,就需要保温,所以在冷藏室和冷冻室与外壳间填充保温材料,冰箱发泡层是一种保温材料,工厂生产冰箱时就在冰箱背面留一个孔,发泡剂就从该孔灌注进去,它会迅速膨胀并充满里面的空隙,固化后就和塑料泡沫一样,主要起保温的作用,现有这种发泡层一般采用聚氨酯,硬质聚氨酯具有优良的物化性能和易于成型加工的优点。其良好的结构强度、极低的导热系数、耐水性、隔音防震效果优良及其声学性能、电学性能和耐腐烛性、无毒性无剌激性以及简单方便的施工方法等特性。使其在石油化工管道、冰箱、冷柜、家具、包装及建筑等方面的应用越来越广泛,“十一五”期间颁布的“节能减排”的国策,使硬质聚氨酯在保温材料里面临着更大的挑战和机遇。由于硬质聚氨酯的多孔性,使其比表面积很大,导致其在空气中极易燃烧。燃烧时会产生较多的有毒有害的烟气,对人们的生活和环境造成了威胁。
因此,在不影响硬质聚氨酯保温性能的前提下,提高聚氨酯的阻燃性能极为迫切。
发明内容
针对现有技术的不足,本发明的目的在于提供一种硬质聚氨酯,用于提高聚氨酯的阻燃性能。
为达到上述目的,本发明的技术方案是:用于冰箱发泡层的阻燃硬质聚氨酯,原料包括白料、黑料,白料包括聚醚多元醇、叔胺类催化剂、氮磷膨胀型阻燃剂、稳定剂、发泡剂,所述黑料为异氰酸脂;原料按质量份数的比例为:聚醚多元醇70~100份、叔胺类催化剂1~5份、氮磷膨胀型阻燃剂15~20份、稳定剂5~10份、发泡剂20~30份、异氰酸脂150~200份。
制作用于冰箱发泡层的阻燃硬质聚氨酯的方法,包括如下步骤:
a、混合搅拌:将白料按比例加入反应器中,搅拌100s直至混匀,搅拌速度为1200~1800r/min;将一定比例的黑料加入反应器中,再次搅拌,初始搅拌速度为400~600r/m,搅拌50s后,搅拌速度上升至1200~1800r/min;
b、发泡:观察到混合物料发白,将混合物料倒出,放入模具内常温发泡;
c、熟化:泡体停止生长,调节温度到55~80℃,保持恒温48h,脱模即得到硬质聚氨酯泡沫塑料。
本发明的有益效果:(1)催化剂使用的是叔胺类化合物,叔胺类催化剂都有很强的催化作用,尤其是对一NCO与一OH反应的催化作用更加明显。前者能促进聚合物分子链迅速增长,粘度快速增加,泡沫网络骨架强度迅速提高。后者能促进-NCO与水反应,迅速产生二氧化碳气体,使聚合物体积迅速增大、膨胀,具有选择性好,辐射移点性好的特点,同时泡沫密度低。(2)现有技术中,聚氨酯材料的阻燃使用阻燃剂分为无机阻燃剂和有机阻燃剂。无机阻燃剂主要有镁系、铝系和硼系等,无机阻燃剂环保,但存在添加量大,且无机阻燃剂与聚氨酯相容性差;有机阻燃剂分为卤系、磷系、氮磷系、氮系阻燃剂,卤系阻燃剂以其性价比高受到人们的亲睐,但其燃烧时容易释放有毒的HCl、HCN和CO气体,并有可能产生对人体有致癌作用的二恶英物质,因此在发达国家其使用受到限制,而本发明使用的的氮磷膨胀型阻燃剂是集氮磷系、氮系和磷系阻燃剂优点于一身的新型阻燃剂。本发明通过叔胺类化合物和氮磷膨胀型阻燃剂有机的结合在一起,制备的硬质聚氨酯时间短,品质高,成本更低;作为冰箱的保温层使用,既保证了保温效果,同时无毒无害,阻燃效果更佳。
作为本方案的进一步优选,催化剂为叔胺类化合物,叔胺属于中等强度的碱性萃取剂,具有选择性好,辐射移点性好的特点,泡沫密度低,经研究发现,叔胺类催化剂具有协同作用,本发明采用的是4:1的二甲基乙醇胺和三亚乙基二胺混合催化体系,经大量事实验证,上述混合催化体系能有效地提高反应的催化效果,缩短泡沫体制品的熟化时间,使生产效率提高。
作为本方案的进一步优选,氮磷膨胀型阻燃剂有以下原料制备:包括甲基磷酸二甲酯、五氧化二磷、亚磷酸三苯酯、季戊四醇、辛酸亚锡和三聚氰胺;使用上述原料制备的阻燃剂,可使聚氨酯以凝聚相阻燃机理为主,在燃烧过程中磷化合物受热分解生成偏磷酸,偏磷酸在高温下聚合生成聚偏磷酸,聚偏磷酸玻璃体不仅覆盖于燃烧体表面,形成一保护膜,能隔绝氧气、起阻燃作用,而且磷酸和聚偏磷酸都是强酸,有很强的脱水性,能使聚合物脱水炭化,在其表面形成炭化层,从而使聚合物内部与氧隔绝,阻止燃烧。同时,由于炭化层的导热性能差,因此能使聚合物与外界热源隔绝,从而在减缓热分解反应,同时又防止和减少了甲烷、一氧化碳等气体的生成和逸出,起到了阻燃的作用。
作为本方案的进一步优选,稳定剂为有机硅泡沫稳定剂,泡沫稳定剂具有3个作用:①乳化作用:通过减弱体系的表面张力来提高各原料的相容性。②成核作用:气泡形成的初始阶段,促进气泡的稳定形成,通过调节泡孔的大小及分布的方式起作用。③稳定作用:制备过程中,通过改善原料体系的稳定性和流动性,达到硬泡制备密度均勻的效果。有机硅泡沫稳定剂适用范围最广,能达到离火自熄,使用更安全。
作为本方案的进一步优选,发泡剂为等比例的环戊烷和异戊烷,泡沫的芯密度低,流动性和脱模性更高,泡沫密度分布更加均匀,脱模时间降低,从而降低发泡剂的成本,正戊烷-异戊烷的气体显示出绝对的优越的绝热性能。
