Description
技术领域 technical field
本实用新型属于建筑声学的微穿孔吸声材料技术领域。The utility model belongs to the technical field of micro-perforated sound-absorbing materials for architectural acoustics.
背景技术 Background technique
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C N1307957A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。The micro-perforated sound-absorbing material is a thin sheet perforated with a large number of micro-perforations with a diameter less than 0.6 mm, and the perforation rate of the micro-perforations (perforation area to the area of the thin sheet) is less than 6%. Due to the large sound resistance of the micro-perforation, when there is a cavity behind the sound-absorbing material, the material and the rear cavity can form a micro-perforated plate sound-absorbing structure with a wide sound-absorbing frequency band and a large sound absorption coefficient. sound. The sound absorption performance of the micro-perforated panel sound-absorbing structure is determined by the micro-perforated aperture, the number of layers of the sound-absorbing panel, the perforation rate and the rear cavity. Generally, the smaller the micro-perforated aperture, the better the sound-absorbing performance. "Practical Building Sound Absorption Design Technology" China Architecture and Building Press. Micro-perforated sound-absorbing materials do not need filling materials, are light in weight, environmentally friendly and hygienic, and have good sound-absorbing performance. However, micro-perforated sound-absorbing materials have always had the disadvantages of difficult processing and high processing costs due to the small diameter of the holes to be processed. Chinese Patent Publication No. CN1307957A patent, on August 15th, 2001 disclosed the technical scheme called " a kind of method and product of processing microporous metal plate ", and its background technology paragraph states that laser processing cost is expensive, therefore proposes the following Metal micro-perforated plates are processed by corrosion method to improve efficacy and reduce processing costs. However, this production process is still relatively complicated, and the production cost is still relatively expensive.
中国专利授权公告号C N201111890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。Chinese patent authorization announcement number CN201111890 patent, on September 10, 2008, disclosed the technical solution titled "a kind of micro-perforated sound-absorbing material", which provides a micro-perforated aluminum foil that can be made by continuous rolling perforation with licker-in rollers. This micro-perforated aluminum foil has a small perforation hole size, good acoustic performance, low price and easy to use. However, this kind of micro-perforated aluminum foil itself is not stiff enough, so it needs to be installed with a skeleton.
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V U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。Corrugated originally refers to the tiles and corrugated tubes of building roofs, but now generally refers to sheet materials with convex and concave folds or strips, such as color steel plates for building roofs and corrugated cardboard for packaging. Corrugated cardboard is generally formed by bonding V-shaped, U-shaped and V U-shaped corrugated paper with face paper. The paper material, flute height and number of layers can be selected according to the packaging design requirements. Corrugated cardboard also includes Y-PLY super strong corrugated cardboard and serpentine corrugated cardboard. The so-called Y-PLY super-strength corrugated board is a kind of corrugated board whose corrugated direction is criss-crossed and has relatively high compressive strength in all directions. The so-called snake-shaped corrugated paper is a kind of corrugated paper with a serpentine shape, which has the advantages of reducing the gap between the vertical compressive strength and the parallel compressive strength, and even if it is not bonded to the surface paper, the corrugated paper produced by it will The shape can also remain unchanged for a long time.

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。As is known, the decoration process often uses materials that are covered with convex and concave bending surfaces of different sizes, but still remain flat macroscopically, such as crumpled but flattened cloth, or patterned aluminum foil. This kind of convex and concave wrinkles, in addition to making people feel the thick texture of the material, can also cover up the spots, creases and other defects on the surface of the raw material. It is known that the fan surface, the umbrella surface and the piano case can be scaled by using the folding principle. It is well known that the Hobermann sphere (U.S. Patent No. 4780344 in 1988) is a structure formed by a plurality of folded surfaces or components in a helical interlocking manner. stretch and retract.
