Abstract

本发明公开了一种多层复合橡塑发泡保温材料及制备方法，所述复合橡塑发泡保温材料包括两层结构，所述两层结构包括保温层和第一功能层，所述保温层和所述第一功能层均为橡塑发泡材料；所述第一功能层与所述保温层通过共混挤出并经硫化发泡一体成型，所述第一功能层与所述保温层为整体结构。本发明提供的多层复合橡塑发泡保温材料，采用硫化发泡一体成型工艺，在确保保温层绝热保温的性能以外，其功能层通过选取不同的功能高聚物，以此赋予功能层相应的功能，从而满足工程应用上的各种个性化需求。

Description

一种多层复合橡塑发泡保温材料及制备方法
技术领域
本发明涉及橡塑发泡保温材料领域，具体涉及一种多层复合橡塑发泡保温材料及制备方法。
背景技术
传统的NBR/PVC体系橡塑发泡保温材料已经广泛应用于中央空调系统的保温、管道系统的隔热等领域。然而，这类传统的NBR/PVC体系橡塑发泡保温材料通常都是单层发泡而成，由于在建筑领域对保温、防火等性能的刚性要求，单一的配方材料已越来越难以满足一些特定工程的个性化需求，如外观色彩、耐寒、耐高温等。
一种方法是采用单一的功能性橡塑保温材料，虽然可以在某些方面具有突出的性能，但在保温、防火性能上存在不足，例如 SLT在耐寒性上有优异的表现，可防火性能则明显不足(LOI＝30，GB/T 2406)，而建筑保温领域要求LOI≥32。
另一种常见的做法是通过胶粘的方式在保温材料表面覆合一层贴面(铝箔或玻璃纤维)，这种方式具有工序复杂、成本贵、贴面材质影响橡塑保温的柔性导致安装困难等缺点。
发明内容
针对现有技术中存在的缺陷，本发明的目的在于提供一种通过共混挤出并经硫化发泡一体成型的多层复合橡塑发泡保温材料及制备方法。
为达到以上目的，本发明采取的技术方案是：一种多层复合橡塑发泡保温材料，所述复合橡塑发泡保温材料包括两层结构，所述两层结构包括保温层和第一功能层，所述保温层和所述第一功能层均为橡塑发泡材料；所述第一功能层与所述保温层通过共混挤出并经硫化发泡一体成型，所述第一功能层与所述保温层为整体结构。

第一功能层和第二功能层均包括：NBR、功能高聚物、增塑剂、发泡剂、填充剂、阻燃剂、促进剂和硫化剂；
其包括如下步骤：
混炼：分别将保温层、第一功能层和第二功能层中的原料混合均匀，混合温度为130℃～160℃，冷却到90℃以下后出片，得到均未硫化发泡的保温层胶片、第一功能层胶片和第二功能层胶片；
具体地，将保温层中的NBR、PVC、增塑剂、发泡剂、填充剂、阻燃剂投入密炼机中混合，得到保温层混炼胶；将保温层混炼胶排放到开炼机上混合、冷却，向开炼机中加入促进剂和硫化剂，混合均匀后出片，得到保温层胶片；

上述的保温层采用传统NBR/PVC橡塑共混硫化发泡配方体系，是以NBR/PVC为基材、满足GB/T17794的橡塑发泡材料所采用的常用配方。
上述的功能高聚物可包括所有类型的聚合物，例如但不限于ACM、AEM、AU、EU、BR、BIIR、CIIR、ECO、EPM、EDPM、EVM、SBR、NBR、FKM、PM、IR、NR、PE、PP、PET、PBT、PC、PA、PU、PTFE、PMMA等。上述原料可以根据实际功能需求，进行组合搭配，形成该功能高聚物，以赋予第一功能层相应的功能，比如耐老化、耐撕裂、耐高温、耐寒、防霉抗菌等。
上述第一功能层和第二功能层中的NBR在功能层中起到相容剂的作用，并对保温层与第一功能层或对保温层与第一功能层和第二功能层中的硫化体系实现同步硫化产生积极的影响，保证多层复合材料的一体发泡成型。
本发明与无发泡橡塑多层复合材料有本质的区别，对于多层共混发泡材料而言，要求不同的组分协同发泡、一体成型，也就是不同组分的发泡速度要保持一致；而发泡材料的交联硫化程度必须与发泡速度达到一个平衡才可以生产出具备低密度低导热率和高阻水汽渗透的产品，这就要求不同的组分在成型过程中确保发泡速度和交联程度一致。而如果不同的组分采用同样的发泡硫化体系，就可以解决发泡速度和交联程度匹配的问题。
上述增塑剂为磷酸盐/酯增塑剂、石蜡油、氯化增塑剂或它们的混合物，具体为氯化石蜡或磷酸三甲苯酯、DOP、DINP、石蜡油中的一种或几种的混合物；
发泡剂可包含有机发泡剂和/或无机发泡剂的至少一种化学发泡剂，具体为偶氮二甲酰胺；
填充剂为炭黑、白炭黑、铝化合物、基于矿物的材料或基于硅的化合物，或它们的混合物，如炭黑、白炭黑、氢氧化铝、滑石粉、陶土、碳酸钙中的一种或几种的混合物；
阻燃剂包括含硼、铝、锑、磷、卤素、钼、铜和氮的一种或几种元素的化合物，例如氢氧化铝、氢氧化镁、氧化钼、八钼酸铵、三氧化二锑、硼酸锌中的一种或几种的混合物。
还可以在上述功能层中添加颜料，以赋予功能层不同颜色，颜料可以是无机颜料或/和有机颜料，如酞青蓝、橡胶大红、橡胶绿、钛白粉、炭黑中的一种或几种的混合物。
以下通过5个实施例和2个对比例对本发明进行详细说明。
下述各个实施例和对比例的保温层均相同，对于5个实施例的制备方法，实施例4采用上述制备三层保温材料的方法进行制备，其余四个实施例和对比例采用上述制备双层保温材料的方法进行制备。各个实施例和对比例的配方如下表1所示。
表1：实施例1～5及对比例1～2配方
表1中，实施例中的保温层、第一功能层以及第二功能层均是按照重量百分比计算，对比例中的各原料同样按照重量百分比计算。
其中，各实施例和对比例中的功能高聚物的配比见下表2所示。
表2：功能高聚物配比
实施例1 实施例2 实施例3 实施例4 实施例5 对比例1 对比例2
NBR 80％
BR 10％ 25％ 10％ 5％ 45％ 15％
NR 60％ 70％
EPDM 60％ 70％ 30％ 65％
POE 30％ 20％
EVA 10％ 15％ 25％ 30％ 20％
将各实施例和对比例在完成混炼工序并制得混炼胶片后，分别取样，在无转子发泡硫化仪做硫化曲线和发泡曲线。
图1和图2分别为4min、170℃下的发泡曲线和硫化曲线，从图1中可以看出，曲线1至曲线7非常接近，说明实施例1～5的功能层和对应的保温层具有同等的发泡速度，从图2中可以看出，曲线1至曲线7非常接近，说明实施例1～5的功能层和对应的保温层具有同等的硫化速度，因此，采用本发明制备方法，功能层与对应的保温层具有同等的硫化和发泡速度，可以实现同步硫化和发泡成型。而对比例1～2的硫化曲线和发泡曲线与保温层对比则显示了较大的差异，在成型过程中难以实现同步硫化和发泡。结合表3的试验结果也进一步验证了实施例1～5可以制备出一体成型的复合橡塑发泡保温材料，对比例1～2则在硫化发泡过程中脱层、撕裂，未能形成复合材料。
表3：实施例和对比例性能特点
材料 性能特点
实施例1 双层复合 第一功能层为红色，主体颜色为黑色
实施例2 双层复合 第一功能层为绿色，耐撕裂,
实施例3 双层复合 第一功能层为红色，耐老化、高温
实施例4 三层复合 第一和第二功能层为红色，耐老化、高温
实施例5 双层复合 第一功能层为绿色，耐寒、耐低温
对比例1 脱层，未复合 第一功能层为灰色
对比例2 脱层，未复合 第一功能层为红色
对比例3 ArmafelxHT 耐高温，应用于125℃以下管路绝热
对比例4 DurkflexSLT 深冷绝热应用
上述对比例3和对比例4为市面销售单层橡塑发泡保温产品。
参见表1和2中，在实施例2中添加了NR，天然橡胶NR作为主体骨架材料，因其是一种结晶性橡胶，自补强性大，具有非常好的机械强度、弹性及耐屈挠性，可以给复合材料提供足够的耐撕裂性能；另外在第一功能层分中掺混适量的NBR和PVC是为了采用协同的交联发泡体系，在双组分共混挤出发泡工艺中控制复合材料的一体发泡成型。因此，在表3中，实施例2表现为耐撕裂。
同样，实施例3和4中添加了EPDM，EPDM(三元乙丙橡胶)单体作为主体骨架材料，因其主链由化学稳定的饱和烃组成，故其具备优异的耐臭氧、耐热、耐候等耐老化性能；另外在功能层中掺混适量的NBR是为了采用协同的交联发泡体系，在共混挤出发泡工艺中控制复合材料的一体发泡成型。因此，在表3中，实施例3和4表现为耐老化。
表4：实施例和对比例综合性能测试结果
表4中各个参数均根据GB/T17794-2008橡塑发泡保温材料性能测试条件为根据进行测试而来的。
表5：实施例功能层性能测试结果
通过上表3～5可见，本发明制备的复合橡塑发泡保温材料由于其一体发泡成型的柔性特点保持了传统柔性保温材料的绝热、隔音及经济、易安装等性能，它的突出优势在于通过功能功能层的创新设计，可以实现不同的性能要求，从而满足各种保温绝热工程的个性化需求。
相比传统单一的NBR/PVC体系橡塑发泡保温材料，采用本发明提供的制备方法制备的多层复合橡塑发泡保温材料，在确保保温层绝热保温的性能以外，其功能层通过选取不同的功能高聚物，以此赋予功能层相应的功能，从而满足工程应用上的各种个性化需求，如表观颜色多样性、耐老化、耐撕裂、耐高温、耐寒、防霉抗菌等。相比材料表面覆裹各种功能贴面，比如铝铂、纤维布、涂料、塑料膜等，这些贴面都或多或少具有刚性材料的缺点，不便于安装而且工序复杂；而本多层复合橡塑发泡保温材料生产工序简单、一体成型，保持了橡塑发泡材料的柔性即安装便利性。相对单一的功能性橡塑发泡材料，例如Armafelx HT、Durkflex SLT等，这些材料虽然在某一方面具有突出的性能表现，但综合性能表现并不好，导热系数或/和防火性能或/和水汽渗透性能低于普通NBR/PVC橡塑发泡材料，通常地这类材料生产成本偏高售价也高；而众所周知NBR/PVC是目前市面上性价比最优的橡塑发泡保温材料，本发明多层复合橡塑发泡保温材料的保温层是NBR/PVC，可以发挥最优的保温性能兼具特殊个性化性能，同时生产成本也不高。
本发明不局限于上述实施方式，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围之内。本说明书中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
