Description
技术领域
本发明涉及保温材料技术领域，具体为一种橡塑绝热保温材料。
背景技术
保温材料一般是指导热系数小于或等于零点二的材料，具有导热系数低、密度小、柔韧性高、防火防水等特性，保温材料发展很快，在工业和建筑中采用良好的保温技术与材料，往往可以起到事半功倍的效果。建筑中每使用一吨矿物棉绝热制品，一年可节约一吨石油，建筑物隔热保温是节约能源、改善居住环境和使用功能的一个重要方面，建筑能耗在人类整个能源消耗中所占比例一般在30％～40％，绝大部分是采暖和空调的能耗，故建筑节能意义重大，而且由于该隔热保温涂料以水为稀释介质，不含挥发性有机溶剂，对人体及环境无危害，其生产成本仅约为国外同类产品的五分之一，而它作为一种新型隔热保温涂料，有着良好的经济效益、节能环保、隔热效果和施工简便等优点而越来越受到人们的关注与青睐，且这种太空绝热反射涂料正经历着一场由工业隔热保温向建筑隔热保温为主的方向转变，由厚层向薄层隔热保温的技术转变，这也是今后隔热保温材料主要的发展方向之一。太空反射绝热涂料通过应用陶瓷球型颗粒中空材料在涂层中形成的真空腔体层，构筑有效的热屏障，不仅自身热阻大、导热系数低，而且热反射率高、减少建筑物对太阳辐射热的吸收、降低被覆表面和内部空间温度，因此它被行家一致公认为最有发展前景的高效节能材料之一。
当今，全球保温隔热材料正朝着高效、节能、薄层、隔热、防水外护一体化方向发展，在发展新型保温隔热材料及符合结构保温节能技术同时，更强调有针对性使用保温绝热材料，按标准规范设计及施工，努力提高保温效率及降低成本，国内外纷纷展开薄层隔热保温涂料的研究，美国已有多家公司生产这种绝热瓷层涂料，这种太空绝热瓷层是根据美国航空和航天宇宙航行局NASA控制航天飞机热传导的工作原理研制而成的，适用于高压喷涂、无污染，具有良好的抗热辐射、薄层隔热、防水防腐蚀等性能，而国内也有多家企业在研发该类材料，如薄层隔热反射涂料、太阳热反射隔热涂料、水性反射隔热涂料、隔热防晒涂料、陶瓷绝热涂料等等，主要是采用耐候性好、耐水性强、耐老化性强、有较强粘结力和弹性的、且能与保温填料、反射填料相溶性好的成膜材料，选择质轻中空、耐高温、热阻大、并具有良好反射性和辐射性的填料、折光系数高、表面光洁度高、热反射率及辐射率高的超细粉料适合作为反射填料，与成膜基料一起构成低辐射传热层，可有效隔断热量的传递，这种薄层隔热反射涂料与多孔材料复合使用可用于建筑物、车船、石化油罐设备、粮库、冷库、集装箱、管道等不同场所涂装。
近年来的火灾事故中，超过死亡数百分之八十的人员致死原因与建筑材料燃烧产生的浓烟和毒气有关，随着越来越多的公共场所、大型建筑物投入使用，建筑物的防火以及燃烧时对人体的影响受到广泛重视，然而，传统的建筑材料中保温材料使用的是PVC体系橡塑发泡保温材料，其配方体系中含有PVC等含卤原料，当火灾发生时，其燃烧放出大量的有毒烟雾和腐蚀性卤酸，造成的人员伤亡远远大于火灾本身，为此，我们提出一种橡塑绝热保温材料。
