Embodiment Construction

[0038] Embodiments of the invention will be specifically described below with reference to the drawings.

[0039] 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.

[0040] 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

The present invention provides a foamed resin laminate sound insulation board capable of exhibiting sound proofing performance, which is free from restrictions of shape, applicable place and weight, thinned as the whole laminated plate to enhance plastic workability such as press work, and provided with sufficient vibration damping performance in a final using state after heating foaming process. This foamed resin laminate sound insulation board 1 is a laminated plate comprising at least an unfoamed foamable resin 3a to be foamed at a foaming temperature by heating and a hard plate 2.

Description

technical field [0001] The present invention relates to a laminated board comprising a hard board such as metal or industrial plastic and foamed resin. Background technique [0002] 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. [0003] 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 vibration-damping material from both sides with a hard board and a restraining board, and then heating or pressurizing in this state to bond the parts together to complete lamination integration. Therefore, the laminate is formed into a predetermined shape by plastic working such ...
