本発明は、衝撃を緩和し、振動を抑制する高性能な緩衝
・制振パネルの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a high-performance shock absorbing/vibration damping panel that alleviates impact and suppresses vibration.

響をおよぼすことがあった。In general, shock absorbing/damping panels are produced by forming and drying a shock absorbing/damping sheet on a base material such as non-woven fabric, and then attaching it closely to the surface plate using an adhesive such as polyvinyl acetate. . However, with this method, the cost of adhesion is high, and the presence of the base material of the buffer/damping sheet and the hardened adhesive on the contact surface may have an adverse effect on the vibration damping effect of the panel.

の製造法である。The present invention involves mixing flaky powder such as mica or talc, or spherical or amorphous powder such as silica or alumina into an aqueous resin dispersion of polyurethane resin that has excellent adhesion to the surface plate when dry. Stir with a stirrer etc. to uniformly disperse,
This is a method for manufacturing shock absorbing/damping panels in which foam is foamed using a mixer, etc., and then directly coated onto a surface plate made of wood or polymer material using a roll coater or knife coater, and then heated and dried.

液に粉体を混合させ、発泡した液のことである。In the drying process, when molding on a base material such as a nonwoven fabric as in the past, the drying temperature was 120 to 180 ° C, but in the manufacturing method of the present invention, it is directly applied and molded on the surface, Since it is introduced into the dryer together with the surface plate and dried, one side of the foaming liquid layer is covered by the surface plate, and at conventional drying temperatures, only the surface layer of the foaming liquid hardens first. , which hindered the evaporation of water. Therefore, in the manufacturing method of the present invention, the drying temperature is set at 80 to 110°C, and the drying time is increased to 30 to 90 minutes, which is longer than conventional methods.
This enables complete and efficient drying of the foamed liquid layer. Note that the thickness of the buffer/damping sheet formed by this manufacturing method is preferably 10 mm or less. The foaming liquid here refers to a liquid obtained by mixing powder with an aqueous resin dispersion and foaming the mixture.

い。In the present invention, a resin aqueous dispersion containing powder is directly applied to the surface plate and dried, so the buffering/damping sheet formed on the surface plate is created by the anchoring effect of the polyurethane resin. Since it is in close contact with the surface plate and there is no adhesive or nonwoven fabric, the damping effect is not impaired.

されているので、本実施例の有効性が明瞭である。In this example, the resin content of the aqueous resin dispersion was 50%,
Phlogopite with a particle size of 1500 μm was mixed at 140 parts by weight with respect to 100 parts by weight of the resin, and the expansion ratio was set to 6 times.
On top of that, use a 2.5 mm thick plywood as a surface plate with a thickness of 6 mm.
11II11 and dried at 100'C for 60 minutes to obtain a buffer/vibration damping panel. Figure 1a shows the amount of vibration attenuation, including the buffering and damping effects, when an impact is applied from the surface plate side of this buffering and damping panel. In addition, the figure shows a sheet obtained by coating and molding an aqueous resin dispersion having the same formulation as in this example on a nonwoven fabric at the same foaming rate and the same thickness, and drying it.
This is the amount of vibration attenuation of a buffer/vibration damping panel manufactured using a conventional manufacturing method, which is adhered to m-thick plywood using a polyvinyl acetate adhesive. In the conventional manufacturing method, the vibration damping amount in the frequency band from about 200 II z to about 500 Hz is lower than this example because of the hardened adhesive and nonwoven fabric, and this example is effective. It is shown. Since vibration damping in this frequency band is generally considered difficult, the effectiveness of this embodiment is clear.
