Description
技术领域
本发明涉及隔热材料技术领域，尤其涉及一种TPO反光隔热发泡材料。
背景技术
防水与隔热材料是建筑行业常用的重要材料，隔热材料可以阻隔建筑物对太阳辐射热量的吸收，防止建筑物表面因吸收太阳辐射热量导致温度升高。防水材料长期在阳光辐射下也会出现老化的问题，影响使用寿命，所以一般会结合反光隔热材料一起使用。
现有技术中，一般在防水材料外面再复合一层反光隔热层，常见的反光隔热层使用的材料有铝箔。但由于是在PE或PET塑膜上镀铝，本质属于塑膜，在外露使用时，一般二年内塑膜会老化，完全失去原来的反光作用。而且铝箔是很薄的金属铝片，抗拉性差、易刺穿，支撑性较弱，有厚度限制、不可承压。
另一种方法就是在防水材料中外刷一层涂料，涂料中添加反光隔热材料，但是反光隔热涂料的涂层性能受外界影响的因素很多，其暴露在大气中，经常受到阳光、雨水风沙等作用，易受沾污，时间久了表面容易变脏，颜色变深，从而导致热反射性能大幅度降低。
发明内容
针对现有技术中缺陷与不足的问题，本发明提出了一种TPO反光隔热发泡材料，将反光材料加入到TPO材料中发泡，得到的TPO发泡材料在其自身具有很好隔热性能的情况下增加了对太阳辐射的反射功能，用于建筑上能减少建筑物对太阳辐射热的吸收，可以防止建筑室内温度上升以及对屋面防水材料起到保护作用。
本发明解决其技术问题所采用的技术方案是：
一种TPO反光隔热发泡材料，包括至少一层TPO发泡材料，所述TPO发泡材料里面设有反光粉；
所述TPO发泡材料单层的配方包括以下重量份的组分：
TPO 50～80份，AC发泡剂2～20份，反光粉2～20份，玻璃微珠1～10份，抗老化剂0.1～1份，抗臭氧剂0.1～3份，分散剂0.1～1份，阻燃剂0.1～5份；
上述组分通过模压发泡或连续挤出发泡加工而成。
进一步的，所述TPO发泡层最外层的表面压制有花纹，所述花纹大小为0.5～3mm，花纹间隙为0.1～3mm，花纹凸起高度为0.1～2mm。
进一步的，所述花纹采用米粒纹。
进一步的，所述反光粉为金属氧化物粉体。
进一步的，所述金属氧化物可以选用三氧化二铁、二氧化锰、三氧化二钴、氧化铜中的一种或多种混合。
进一步的，所述TPO发泡材料采用多层复合时，其相邻层之间设有玻璃纤维层或丙纶无纺布层。
进一步的，所述TPO发泡材料表面可设有耐刺穿橡胶层，其底面设有丁基橡胶粘合层。
进一步的，所述TPO发泡材料与各层之间采用热复合或硫化挤压一体成型。
进一步的，所述TPO发泡材料的发泡倍率为2～50倍。
本发明具有如下有益效果：本发明在TPO材料中添加金属氧化物的反光粉一起发泡，其可以把吸收的日照光线和热量以一定波长反射到空气中，而且TPO发泡材料本身具有很好隔热功能，其导热系数极低的空心玻璃 微珠隔绝热能的传递，即使在大气温度很高时也能阻隔外部热量向物体内部传导。
本发明将TPO发泡材料的隔热功能结合反光功能，能够减少建筑物对太阳辐射热的吸收，阻止建筑物表面因吸收太阳辐射导致温度升高，减少热量向室内传递，同时对屋面防水材料起到了保护作用，提高了防水材料的使用寿命。
本发明TPO发泡材料自身还具有轻量化、耐老化和很好的防水功能，当采用多层TPO发泡材料复合使用时，其具有反光、隔热和防水等多种功能于一体。
本发明将反光与隔热功能合为一体，加工方便，减少施工步骤，避免了现有技术中要涂刷反光涂料或复合反光铝箔膜，节省人力，省时省力，节约成本。
附图说明
图1为本发明结构示意图；
图2为本发明米粒型花纹示意图。
具体实施方式
下面结合附图对本发明的具体实施方式进行详细说明。
实施例一：
如图1所示，一种TPO反光隔热发泡材料，包括两层TPO发泡材料1，所述TPO发泡材料里面设有反光粉，所述反光材料为三氧化二铁粉体。两层TPO发泡材料1之间设有玻璃纤维层，提高了TPO发泡材料的抗拉强度。所述TPO发泡材料表面设有耐刺穿橡胶层2，可有效保护内部的TPO发泡层，防止材料在运输、施工过程中意外磨损，同时可以有效防止TPO发泡层自身的老化。TPO发泡材料的底面设有丁基橡胶粘合层3，便于施工安装。
上述反光隔热发泡材料各层之间采用热复合而成。
其TPO发泡材料单层的配方由以下重量份的组分组成：
TPO 70份，AC发泡剂10份，反光粉10份，玻璃微珠8份，抗老化剂0.6份，抗臭氧剂1.5份，分散剂0.5份，阻燃剂3份；其通过连续挤出发泡加工而成，发泡倍率为10倍。
其中抗老化剂可采用GW-540，抗臭氧剂选用防老剂TPPD，分散剂采用乙二醇，阻燃剂选用氧化镁。
本发明在TPO材料中添加金属氧化物的反光材料一起发泡，其可以把吸收的日照光线和热量以一定波长反射到空气中，而且TPO发泡材料本身具有很好隔热功能，其导热系数极低的空心玻璃微珠隔绝热能的传递，即使在大气温度很高时也能阻隔外部热量向物体内部传导。
如图2所示，本发明TPO发泡层最外层的表面上压制有特殊的米粒型花纹，所述花纹大小为0.5～3mm，花纹间隙为0.1～3mm，花纹凸起高度为0.1～2mm。其设置米粒型的小花纹，可以将太阳辐射的光线反射、散射出去，进一步提高本发明TPO发泡材料的反光功能。
本发明采用单层TPO发泡材料时，可以配合其它防水材料一起使用，通过本发明TPO发泡材料具有的反光功能，对太阳辐射热量的散射，减少了对下面防水材料的辐射使其老化，从而对防水材料起到了保护作用，提高了防水材料的使用寿命。
本发明采用TPO发泡材料，其中的空心玻璃微珠可以隔绝热能的传递，而且具有轻量化、耐老化，使用寿命长。本发明TPO发泡材料自身还具有很好的防水功能，当采用多层TPO发泡材料复合使用时，其具有反光、隔热和防水等多种功能于一体。
本发明将TPO发泡材料中增加反光材料，以及结合压制特殊的小型米粒花纹，使反光与隔热功能合为一体，加工方便，减少施工步骤，避免了现有技术中要涂刷反光涂料或复合反光铝箔膜，节省人力，省时省力，节约成本。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明的范围内。本发明要求保护范围由所附的权利要求书及其等同物界定。
