Description

一种改性聚氨酯
技术领域
本发明涉及保温材料技术领域，具体涉及一种改性聚氨酯。
背景技术
聚氨酯是现在建筑外墙普遍采用的保温材料，而作为保温材料其阻燃性能自然是最重要的衡量指标之一。现有的多数聚氨酯均是通过添加大量卤代阻燃剂来实现阻燃，这种做法有如下缺点：添加大量卤代阻燃剂不但大幅提高了成本，且卤代阻燃剂本身存在挥发性，其阻燃性能随时间推移会逐渐下降，影响其使用过程中的稳定性；此外，大量卤代阻燃剂的添加还会影响聚氨酯的尺寸稳定性，还会影响其抗压抗拉强度。
发明内容
本发明提供一种不含卤代阻燃剂且阻燃性能良好的改性聚氨酯，该改性聚氨酯成本低，无毒环保，且阻燃性能随时间推移无明显变化，使用稳定可靠。
本发明的技术方案如下：
一种改性聚氨酯，由白料、黑料混合发泡而成，所述白料为组合聚醚，所述黑料为异氰酸酯，发泡过程中需要添加助剂，所述助剂包括催化剂、发泡剂、交联剂、泡沫稳定剂。在发泡过程中，控制所述黑料与白料的质量比大于1.8:1；所述改性聚氨酯制备过程中不添加阻燃剂；所制得的改性聚氨酯具有六元环分子结构，其结构式为
。
以该改性聚氨酯为芯保温层的聚氨酯保温板的制备过程如下：
1)将助剂溶于白料中，通过充分搅拌，让其完全均匀溶于白料中；
2)控制黑料和白料的温度介于20℃-25℃，黑料和白料的质量比大于1.8:1，然后以将黑料和白料抽入高压发泡机设备进行充分混合发泡，经高压混合均匀后，经由枪管浇注在预置在层压机下部传送带上的玻璃纤维水泥毡表面；另一玻璃纤维水泥毡随层压机上部传送带进入层压机中，设定层压机温度为70℃，进行聚氨酯发泡和熟化过程，然后进行切割修边，即得到最终的改性聚氨酯保温板。
传统的聚氨酯要形成高分子链，是通过组合聚醚的羟基和异氰酸酯的羧基交联后形成酯结构。这种结构的聚氨酯本身并没有阻燃特性，因此传统的聚氨酯的阻燃性能是通过添加大量卤代阻燃剂实现。这种做法成本较高，且添加大量的阻燃剂不仅会影响聚氨酯的尺寸稳定性，还会影响其抗压抗拉强度；最重要的是，这类阻燃剂会随时间挥发进而造成聚氨酯的阻燃性能随时间推移下降。本发明中的工艺是通过提高黑料:白料的比例达到1.8:1以上，在发泡过程中，部分黑料(异氰酸酯)和白料(组合聚醚)发生交联反应，形成传统的聚氨酯结构；另一部分黑料(异氰酸酯)在催化剂的作用下发生自聚反应，该自聚反应的产物是具有六元环分子结构的化合物，该化合物本身即具有优异的阻燃性能，因此，本发明的改性聚氨酯无需额外添加卤代阻燃剂，既安全环保，且阻燃性能随时间推移不会降低。
本发明所得的改性聚氨酯不含卤代阻燃剂，但具有更优良的阻燃性能，且成本低、无毒环保、阻燃性能随时间推移无下降。经试验测定，所述改性聚氨酯氧指数不小于32，烟密度等级小于75，导热系数不大于0.024W/m·K。
具体实施方式
下面将结合具体实施方式对本发明实施例中的技术方案进行清楚、完整地描述。
一种改性聚氨酯，由白料、黑料混合发泡而成，所述白料为组合聚醚，所述黑料为异氰酸酯，发泡过程中需要添加助剂，所述助剂包括催化剂、发泡剂、交联剂、泡沫稳定剂。在发泡过程中，控制所述黑料与白料的质量比大于1.8:1；所述改性聚氨酯制备过程中不添加阻燃剂；所制得的改性聚氨酯具有六元环分子结构，其结构式为
。
传统的聚氨酯要形成高分子链，是通过组合聚醚的羟基和异氰酸酯的羧基交联后形成酯结构。这种结构的聚氨酯本身并没有阻燃特性，因此传统的聚氨酯的阻燃性能是通过添加大量卤代阻燃剂实现。这种做法成本较高，且添加大量的阻燃剂不仅会影响聚氨酯的尺寸稳定性，还会影响其抗压抗拉强度；最重要的是，这类阻燃剂会随时间挥发进而造成聚氨酯的阻燃性能随时间推移下降。本发明中的工艺是通过提高黑料:白料的比例达到1.8:1以上，在发泡过程中，部分黑料(异氰酸酯)和白料(组合聚醚)发生交联反应，形成传统的聚氨酯结构；另一部分黑料(异氰酸酯)在催化剂的作用下发生自聚反应，该自聚反应的产物是具有六元环分子结构的化合物，该化合物本身即具有优异的阻燃性能，因此，本发明的改性聚氨酯无需额外添加卤代阻燃剂，既安全环保，且阻燃性能随时间推移不会降低。
以下是本发明的一些具体实施例，各实施例中黑料和白料的质量比发生变化，其他实验条件保持不变。
实施例1
本实施例中黑料和白料的质量比为1.8:1，改性聚氨酯保温板的制备步骤如下：
1)将助剂溶于白料中，通过充分搅拌，让其完全均匀溶于白料中；
2)控制黑料和白料的温度介于20℃-25℃，然后以将黑料和白料抽入高压发泡机设备进行充分混合发泡，经高压混合均匀后，经由枪管浇注在预置在层压机下部传送带上的玻璃纤维水泥毡表面；另一玻璃纤维水泥毡随层压机上部传送带进入层压机中，设定层压机温度为70℃，进行聚氨酯发泡和熟化过程，然后进行切割修边，即得到最终的改性聚氨酯保温板。
实施例2
本实施例中黑料和白料的质量比为1.85:1，改性聚氨酯保温板的制备步骤同实施例1。
实施例3
本实施例中黑料和白料的质量比为1.9:1，改性聚氨酯保温板的制备步骤同实施例1。
实施例4
本实施例中黑料和白料的质量比为1.95:1，改性聚氨酯保温板的制备步骤同实施例1。
实施例5
本实施例中黑料和白料的质量比为2.0:1，改性聚氨酯保温板的制备步骤同实施例1。
对实施例1-5中所得的聚氨酯保温板进行性能测试，包括氧指数、烟密度等级和导热系数的测量以及阻燃性能评估。需要注意的是，在进行氧指数、烟密度等级和导热系数测试前，须剥离或切除聚氨酯保温板表面的玻璃纤维水泥毡层，以确定所测得的数据可以准确反应聚氨酯层的性能。其中，氧指数的测试按照GB/T2406.1-2008和GB/T2406.2-2009的标准执行，烟密度等级的测试按照GB/T8627-2007的标准执行，导热系数的测量按照GB/T10294的标准执行。
实施例1-5中的性能测试结果如下表1所示。
表1实施例1-5的性能测试结果
氧指数 烟密度等级 导热系数(W/m ·K) 阻燃性能
实施例1 36 42 0.023 B1
实施例2 35 44 0.024 B1
实施例3 35 45 0.022 B1
实施例4 34 48 0.023 B1
实施例5 34 47 0.022 B1
可见，实施例1-5中的改性聚氨酯其氧指数均不小于32，烟密度等级小于75，导热系数不大于0.024W/m·K，燃烧等级均为B1级。可见，本发明所得的改性聚氨酯不含卤代阻燃剂，但具有更优良的阻燃性能，且成本低、无毒环保；由于不含挥发性的卤代阻燃剂，因此本发明的改性聚氨酯的阻燃性能随时间推移无下降。
以上对本发明所提供的一种改性聚氨酯进行了详细介绍和具体阐述。显然，以上所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。综上所述，本说明书内容不应理解为对本发明的限制。
