Description

一种微穿孔铝箔
技术领域
本实用新型属于建筑声学的微穿孔吸声材料技术领域。
背景技术
微穿孔吸声材料是一种穿有大量直径小于0.6毫米微穿孔的薄片材,其微穿孔的穿孔率(穿孔面积比薄片材面积)小于6％。由于微穿孔声阻很大,当这种吸声材料后方有空腔时,其材料与后空腔能形成一种吸声频带较宽,吸声系数较大的微穿孔板吸声构造,吸收声音。微穿孔板吸声构造的吸声性能,由微穿孔孔径.吸声板层数.穿孔率和后空腔所决定,一般是微穿孔孔径愈小,其吸声性能愈好。《实用建筑吸声设计技术》中国建筑工业出版社。微穿孔吸声材料无须填充材料,质量轻,环保卫生,吸声性能好。但是,微穿孔吸声材料因需要加工的孔径很小,因而一直存在着加工难,加工费用很贵的缺陷。中国专利公开号ＣＮ1307957Ａ专利,于2001年8月15日公开了名称为《一种加工微孔金属板的方法和产品》的技术方案,其背景技术段陈述了激光加工成本贵,因此提出以腐蚀法加工金属微穿孔板,提高功效,降低加工成本。但是,这种生产工艺仍然比较复杂,生产成本仍然比较贵。
中国专利授权公告号ＣＮ201111890专利,于2008年9月10日公开了名称为《一种微穿孔吸声材料》的技术方案,提供了一种可用刺辊连续滚动穿孔制成的微穿孔铝箔。这种微穿孔铝箔的穿孔孔径很小,声学性能很好,价格低廉,使用方便。但是,这种微穿孔铝箔自身挺度不够,要用骨架安装。
瓦楞原指建筑屋面的瓦片与楞筒,现在则泛指凸凹有折面或条楞的片状材料,比如建筑用屋面彩钢板和包装用瓦楞纸板。瓦楞纸板一般由呈Ｖ形.Ｕ形和ＶＵ形的瓦楞纸与面纸粘接形成,其纸材料.楞高和层数可按包装设计要求选择。瓦楞纸板还包括Y-PLY超强瓦楞纸板和蛇形瓦楞纸。所谓Y-PLY超强瓦楞纸板,是一种将瓦楞纸的瓦楞方向纵横交错排列的,各向压强度都比较高的瓦楞纸板。所谓蛇形瓦楞纸,是一种楞形呈蛇形弯曲的瓦楞纸,其优点有减小了垂直压强度与平行压强度之间的差距,以及即使不与面纸粘接,其所压出的楞形也能长期保持不变。资料见《瓦楞纸箱生产实用技术》化学工业出版社。《瓦楞包装设计》印刷工业出版社。
公知,装饰工艺经常使用布满大小不等凸凹弯折面,但宏观仍保持平整的材料作装饰,比如揉皱但展平的布料,又比如花纹铝箔。这种凸凹皱折,除了使人感到材料质感厚重,也能掩饰原材料表面的斑点.折痕等暇疵。公知,利用折叠原理能使扇面.伞面和琴箱缩放。公知,霍伯曼球面(美国1988年第4780344号授权专利)是一种由多个折面或构件以螺旋互锁方式形成的结构,不但能按需要展成平面和弧面,而且还能自如地伸展和回缩。资料见《影响美国的100个专利》北京大学出版社。
实用新型内容
本实用新型要解决的技术问题,是提供一种挺度较好,容易安装,吸声性能好的微穿孔铝箔。
为解决上述技术问题,本实用新型采用的技术方案为:一种微穿孔铝箔,包括材料厚度0.12毫米以下,有穿孔率小于5％,穿孔直径小于0.5毫米微穿孔的铝箔,所述微穿孔铝箔的形状为瓦楞状。
本实用新型所述瓦楞状微穿孔铝箔,其楞形可以为蛇形瓦楞。本实用新型所述瓦楞状微穿孔铝箔,其至少一面可以连接有片状微穿孔铝箔,其片状微穿孔铝箔可以有凸凹皱折。本实用新型所述瓦楞状微穿孔铝箔,其至少一面可以连接有另一瓦楞状微穿孔铝箔,两者的瓦楞方向可以相错。本实用新型所述瓦楞状微穿孔铝箔,其至少一面可以连接有铝穿孔板,也可以连接有两条以上的铝线,还可以连接有铝网。
本实用新型使用方式很多,比如制成平板材料以现用天花龙骨安装,又比如卷成灯笼状以钢丝悬挂起来,再比如将其粘接于墙前方的支架前面,都能很好地吸收声音。
本实用新型利用瓦楞折起的立面使微穿孔铝箔既有挺度,又有收展性,容易安装,利用瓦楞立面加大了吸声面的表面积,解决了提供一种有一定挺度,容易安装,吸声性能好的微穿孔铝箔的问题。本实用新型的叠层制品,强度很大,吸声性能很好,容易安装。
