Description
技术领域
本发明涉及一种建筑材料,特别是一种节能阳光膜材料。
背景技术
膜结构是近几十年发展起来的一种新型的大跨度空间结构,它由具有优良性能的织物(膜材)通过支撑构件(如刚性梁、柱、柔性索),或给膜内空气加压以一定的方式组合并施加适当的初始预张力而形成具有一定刚度的空间结构形状,从而承受一定外荷载的一种空间结构形式。它的历史可以追溯到远古时期的人们利用树木的纤维和兽皮建造的帐篷。
中国专利申请号200620043712.2,授权日为2007年11月7日,发明创造名称为一种阳光膜,该申请公开了一种由一层薄膜状的基础支撑层构成,基础支撑成的下侧面复合有一个第一表面层,基础支撑层上侧面有一个第二表面层,第二表面层的外表面上设置一个结合层的阳光膜。其中基础支撑层由聚酯切大有光切片构成,结合层是电晕处理层或化学预处理层。该发明设计的阳光膜光泽度高、雾度低、适合于作为隔热膜、窗膜保护膜、反光膜等的基材薄膜使用。该发明创造由于其支撑层的强度弱,具有力学强度差的缺点。
中国专利申请号201310029492.2,专利公开日为2013年6月26日,发明创造名称为一种储能变色建筑膜材料的制备方法。该申请公开了一种储能变色而建筑膜材的制备方法,包括将PVC粉体、增塑剂混合均匀而制成PVC预浸胶,然后预烘干制备半成品,将PVC粉末、增塑剂、碳酸钙、热稳定剂、光稳定剂、储能微胶囊和变色颜料共混组成的PVC高分子涂层胶涂覆在半制品表面,然后预烘干,最后烘焙而制成吃醋能变色建筑膜材料。该制备方法能够使储能微胶囊和变色颜料在高分子中均匀分散,并且使制备的储能变色建筑膜材料材质均匀,变色均匀,同时涂层膜与基布之间粘结牢度高。该建筑膜材料的制备方法采用相变储能微胶囊、变色颜料添加到PVC高分子涂层中,该PVC建筑膜材具有一定的储能效果,但不具备自发热功能。
中国专利申请号201710461251.3,专利公开日为2017年9月22日,发明创造名称为一种PVC建筑膜材。该申请公开了一种PVC建筑膜材料,由以下原料制成:PVC树脂20~80份,聚氯乙烯22~35份、二硫代氨基甲酸酯11~18份、聚异氰酸酯5~10份、己内酰胺33~45份、2-羟基-4-正辛氧基二苯甲酮1~5份、乙烯-醋酸乙烯-一氧化碳共聚物10~15份、增塑剂1~3份、三氧化二锑1~15份、阻燃剂4~9份、氯丁橡胶1~4份、甲基丙烯酸甲酯8~12份、二氢吡啶3~6份、抗氧剂1~4份、粘合剂1~4份、乙醇22~45份、水12~34份。该发明提供的PVC建筑膜材具有抗氧性能好、具有优良的阻燃、防火性能,且使用寿命长的有点。然而该PVC膜材料在建筑膜材料的关键指标机械性能的强度没有明确的说明。
所以,有必要研制一种机械性能优良、具有降外界的热量吸收,储存到膜内层的阳光膜材料。该阳光膜既可以提供良好的机械性能,又具有调温储能的效果,在农业、工业制造领域具有广泛的用途。
