技术领域
本发明涉及建筑领域，具体是涉及一种钢结构节能外墙体。
背景技术
目前我国城乡住宅竣工建筑面积每年超过10亿平方米，而且在今后相当长的一段时间内，我国住宅建设仍处于增量型发展时期。钢结构住宅体系具有便于实现标准化、部品化，组织进行工业化生产；节能、节水、节地、节材，符合环保及可持续发展的要求等特点。这些特点与住宅产业化的内涵及我国住宅产业化的核心模式---“节约型住宅”的要求相一致，是我国推进住宅产业现代化的较理想的住宅建筑体系。
但传统的钢结构搭配混凝土或者砌体外墙具有一定的缺陷型，如建筑保温性太差，不能满足节约型住宅的要求。一些外墙外体的保温层采用的保温材料虽能达到墙体保温节能效果，但存在防火性和抗裂性能差，易老化寿命短等技术问题，也不利于环保。同时，国内建筑结构基层表面平整度偏差过大，大多数超出外墙外保温的允许偏差范围，因此需要打磨，大大增加了施工周期及工作量。
发明内容
为了克服上述不足，本发明的目的是：提供一种钢结构节能外墙体，该外墙体达到了很好的保温节能的效果；同时还有具有很好的防火性和抗裂性能及耐候性能，并且在节能保温同时还具有环保的特点。
本发明的技术方案是：一种钢结构节能外墙体，它是由钢筋混凝土墙面、内粉刷层、界面层、保温层、防护层和饰面层组成，其特征是：所述的界面层是由乳液、强度等级42.5级硅酸盐水泥、细砂按1:1:1重量比配制成界面处理砂浆；所述的保温层由胶粉聚苯颗粒保温浆料和石墨聚苯板组成。
所述的乳液为高分子乳液。
所述的高分子乳液是有以下重量份的原料组成：硅丙乳液87份、四氯邻苯二甲酸酐5份、聚磷酸铵4份、消泡剂2份和偶联剂2份；所述的聚磷酸铵的分子量为2000。
所述的消泡剂为有机硅类消泡剂；偶联剂为铝酸酯偶联剂。
所述的胶粉聚苯颗粒保温浆料为由硅酸盐类胶粉料、聚苯颗粒轻骨料和水按重量比1：4：8搅拌而成。
所述的聚苯颗粒轻骨料为回收的废聚苯乙烯泡沫材料破碎制成。
所述的石墨聚苯板的尺寸是450mm×600mm长条板，石墨聚苯板用胶粉聚苯颗粒保温浆料找平，不能粘贴石墨聚苯板部位用胶粉聚苯颗粒保温浆料满抹代替。
所述的防护层是由水泥抗裂砂浆与耐碱玻纤网格布复合组成。
所述的水泥抗裂砂浆是由水泥30份、石英砂50份、羟丙基甲基纤维素0.7份、可再分散乳胶粉4份、木质素磺酸钠3份、膨胀珍珠岩9份。
本发明的优点是：该外墙体的保温层采用胶粉聚苯颗粒保温浆料和石墨聚苯板相结合，达到了很好的保温节能的效果，并具有很好的防火性能；本发明的界面层所采用的高分子乳液不仅具有很好的贴合力，并且还具有阻燃的性能；本发明的防护层采用的水泥抗裂砂浆不仅具有较高的粘结强度高、抗压强度和很好的抗裂性外，同时还具有保温隔热性、耐水性、耐候性等性能。
下面通过说明书附图及具体实施例对本发明做进一步详细说明，但不作为对本发明的限定。

具体实施方式
实施例1
一种钢结构节能外墙体，它是由钢筋混凝土墙面1、内粉刷层2、界面层3、保温层4、防护层5和饰面层6组成，所述的界面层3是由乳液、强度等级42.5级硅酸盐水泥、细砂按1:1:1重量比配制成界面处理砂浆；所述的保温层由胶粉聚苯颗粒保温浆料和石墨聚苯板组成。
实施例2
如图1所示，一种钢结构节能外墙体，它是由内粉刷层2、钢筋混凝土墙面1、界面层3、保温层4、防护层5和饰面层6依次顺序组成，所述的界面层3是由乳液、强度等级42.5级硅酸盐水泥、细砂按1:1:1重量比配制成界面处理砂浆；所述的保温层由胶粉聚苯颗粒保温浆料和石墨聚苯板组成。所述的乳液为高分子乳液。
实施例3
在实施例2的基础上，所述的高分子乳液是有以下重量份的原料组成：硅丙乳液87份、四氯邻苯二甲酸酐5份、聚磷酸铵4份、消泡剂2份和偶联剂2份；所述的聚磷酸铵的分子量为2000。所述的消泡剂为有机硅类消泡剂；偶联剂为铝酸酯偶联剂。该高分子乳液在具有很好的贴合力同时，还有阻燃的性能，大大提高了防火性能。

具体施工至少包括如下步骤：
步骤1)施工准备；
步骤2)钢筋混凝土墙面做基层处理；
步骤3)涂界面处理砂浆，形成界面层；
步骤4)保温层施工，先用胶粉聚苯颗粒保温浆料找平，然后铺石墨聚苯板；
