耐黄变聚氨酯泡棉及其制备方法
技术领域
本发明涉及泡棉技术领域，具体涉及一种耐黄变聚氨酯泡棉及其制备方法。
背景技术
聚氨酯是在大分子主链中含有氨基甲酸酯基的聚合物，称为聚氨基甲酸酯，聚氨酯分为聚酯型聚氨酯和聚醚型聚氨酯两大类，具有很多优异的性能，所以其具有广泛的用途。在相同硬度下，聚氨酯材料比其它的弹性体承载能力高、耐磨、抗冲击性高、回弹范围广、不受臭氧侵蚀的影响、耐辐射、抗霉菌高、可在标准设备上加工，也可与木材、金属和大部分塑料粘接，制成降噪音材料，其模塑和加工成本低。聚氨酯泡棉是通过聚氨酯发泡做成的，具有很好的弹性，在日常生活中很常见。现有的聚氨酯泡棉在高湿度、高热度的环境下使用一段时间后，容易发生黄化现象，影响其使用，鉴于此，有必要对传统的聚氨酯泡棉及其制备方法作出改进。

具体地，前述交联剂为六亚甲基二异氰酸酯。
优选地，前述稳定剂为二甲基硅油。
耐黄变聚氨酯泡棉的制备方法，包括以下制备步骤：
S1、将复合多元醇、异氰酸酯、催化剂和水加入至反应釜中，搅拌均匀，加热至65~75℃，反应1~3h；
S2、将反应釜的温度升高至80~95℃，加入扩链剂和交联剂，反应1.5~2.5h；
S3、将反应釜的温度降至52~68℃，加入柠檬酸和稳定剂，搅拌均匀，反应2~3.5h；
S4、向反应釜中充入发泡气体，并将反应釜的压强升至6~9MPa，保持0.5~1h，进行发泡，得到泡棉体；
S5、将泡棉体浸泡于缓冲溶液中0.5~1.5h，并加热至55~65℃，取出后干燥，形成聚氨酯泡棉。
优选地，前述缓冲溶液包括以下重量份数的组分：乙二醇12~20份、柠檬酸15~18份、柠檬酸钠11~16份、乙二酸12~17份、草酸钠10~15份和水8~10份。
