Embodiment Construction

[0037] Embodiments of the invention will be specifically described below with reference to the drawings.

[0038] figure 1 A schematic diagram of a foamed resin laminated sound insulating panel 1 according to Example 1 of the present invention is shown. Such as figure 1 As shown in (a), this foamed resin laminated sound insulating board 1 is laminated sequentially with a foamable resin 3a that can be foamed when heated to the foaming temperature, a non-foamed resin 4 that does not foam even when heated, and a high-rigidity resin. The hard plate 2 (for example, steel plate, aluminum alloy plate, etc.) is integrated.

[0039] In the above-mentioned foamed resin laminated sound insulating panel 1, the foamable resin 3a and the non-foamed resin 4, and the non-foamed resin 4 and the hard board 2 are bonded by heat welding by heating and pressing. The temperature of this thermal fusion has been set lower than the foaming temperature of the foamable resin 3a, preferably lower than...

Abstract

A foamed resin laminated sound insulation board (1) is a laminated board having at least an unfoamable resin (3a) in an unfoamed state that can be heated and foamed at a foaming temperature, and a hard board (2). According to the present invention, it is possible to provide a laminate that is not restricted by shape, construction site, and weight, is thin as a whole, has good plastic workability such as press processing, and has sufficient anti-vibration in the final use state after the heating and foaming process. Foamed resin laminated sound-insulating panel exhibiting sound-insulating performance, etc., and method for producing the same.

Description

[0001] This application is a divisional application of the invention patent application with the application number 03148991.5 and the title of the invention: foam resin laminated sound insulation board and its manufacturing method filed by the applicant on July 3, 2003. technical field [0002] The present invention relates to a laminated board comprising a hard board such as metal or industrial plastic and foamed resin. Background technique [0003] Conventionally, various structures have been proposed as laminated sound-insulating panels in which vibration-damping performance and sound-insulating performance are imparted to hard boards such as metals and industrial plastics. [0004] For example, there may be mentioned a confinement-type vibration damping structure in which a damper material is sandwiched between the above-mentioned hard board and a restraint plate having the same rigidity as the hard board. This laminated board is manufactured by sandwiching the vibratio...
