- An object of the present invention is to provide a breathable sandwich panel that functions as a sound-absorbing material by using a two-cam material filled with a foam material having a breathing structure as a core material and a breathable porous material as a surface material. Propose measures to effectively prevent the filler from falling off from the cells at the edge of the hard cam material (first issue), and bonding that does not impair the breathability of the foam material or porous material It is to propose a method for manufacturing sandwich panels including the use of the agent!
- the first problem is that the cell space of the her cam material is filled with a phenol foam material having an open cell structure, and the vertical and horizontal dimensions of the sheet-like phenol foam material before filling are determined.
- a hard cam structure (claim 1) characterized in that, after filling, the peripheral edge of the hard cam material is trimmed by the filled phenol foam material. Is done.
- the honeycomb material a material made of paper, metal, resin, ceramics or other materials can be selected, and as the filler, a foam material made of a hard foam of synthetic resin such as phenol, urethane, styrene or the like is used. Can be used. In particular, a phenol foam material having an open cell structure is preferable because it exhibits excellent water absorption capability and sound energy absorption performance. If a honeycomb material and a filler are stacked and press-fitted with a press machine, a honeycomb structure in which the honeycomb material cell space is filled with the filler is completed.
- the second problem is that a liquid adhesive having a predetermined viscosity is attached in a narrow strip shape only at the tip of the cell wall facing one side of the hard cam material, and a surface material having air permeability is obtained. And press against the one surface of the honeycomb material to which the adhesive is adhered, before the adhesive is cured. In addition, the foam material having water absorption is pushed into the cell space until it touches the other adhesive force of the adhesive-cam material, and the foam material in contact with the adhesive contains moisture contained in the adhesive.
- the method of manufacturing a breathable sandwich panel includes steps of absorbing hardening to accelerate curing and quickly achieving adhesion of the surface material to the hard cam material (claims)
- the filler is filled even after filling the cell space of the nonicum material.
- the material is not cut apart at the periphery of the hard cam material and remains integrated, and the peripheral portion of the hard material is embedded, so that the filling material does not fall off.
- the filler is exposed around the core material, so that the appearance is easy to process and the end faces are easily aligned.
- a buried plate is partially inserted around the sandwich panel and bonded to the surface material to form a reinforcing seat for mounting parts, etc., or a plywood or a resin plate is placed around the panel. Even when it is inserted and bonded to the surface material, the processing is easy due to the flexibility and ease of cutting of the filler exposed at the periphery of the core material.
- the adhesive adhesion area in the surface material is severely restricted, the obstruction of air permeability can be minimized.
- the location where the adhesive is present is limited to the tip of the cell wall and the hexagonal outline in the surface material with which the tip abuts. Since the cell wall is made thin, the area where the adhesive is present is limited even if it is slightly expanded.
- the adhesive foam is rapidly cured by absorbing the moisture content of the adhesive into the phenol foam material, so that it is possible to accurately prevent the surface material from being displaced from the pressed position. Positioning is achieved.
- the adhesive is cured by filling the concave corners formed by the tips of the orthogonal cell walls and the surface material into a solid fillet shape.
- a projecting portion in which one or both ends in the vertical direction of the her cam material is projected by a predetermined length of the surface force of the filler is provided. (Claim 2).
- the two filler sheets are filled into the cell space of the two-cam material at a longitudinal interval, and the honeycomb Inside the material In the middle of the two filler layers, there is no filler! If there is an air layer! (Claim 3).
- the honeycomb structure with the air layer of the present embodiment, the sound absorbing performance from low frequency to high frequency is improved, and a sound absorbing material for the entire region can be realized.
- the upper and lower side forces of the sheet-like phenol foam material having a thickness exceeding the total height of the two double cam materials A single hard cam material is press-fitted, and a layer in which the hard cam material does not exist and only the filler power is provided is provided in an intermediate portion in the thickness direction of the filler (claim 4).
- the honeycomb structure By providing the honeycomb structure with an intermediate layer (a layer in which no two-cam material is present) that only has the filler of the present embodiment, heat conducted through the honeycomb material wall is blocked by the intermediate layer.
- the foam material constituting the interlayer becomes a heat insulating layer. Increasing the thickness of the intermediate layer improves the heat insulation performance.
- the hard cam material layer located on both sides serves as a protective layer for the foam material.
- the invention of claim 1 or the embodiment according to each of the above embodiments is to manufacture a sandwich panel by using any of the honeycomb structures as a core material and bonding a surface material thereto. At this time, the adhesive applied to the back surface of the surface material can be pressed and adhered to the surface of the core material or the protruding portion (first embodiment) protruding from the surface.
- the embodiment according to the invention of claim 6 is an emulsion adhesive having a predetermined viscosity as the adhesive, wherein the adhesive is attached in a narrow band shape only at the tip of the cell wall. This is achieved by selecting the agent and pouring the adhesive to a predetermined depth in a flat shallow container that is held horizontally, and then immersing only the tip of the cell wall of the hard cam material into it and pulling it up. (Claim 7).
- the adhesive When the adhesive is attached to the tip of the cell wall, the low-viscosity adhesive that flows smoothly flows and a sufficient amount of adhesion cannot be obtained, so that the adhesive has an appropriate viscosity (and surface tension). It is desirable to have In the present invention, the emulsion adhesive is selected because of such viewpoint power. As described in claim 6, the adhesive can be applied in a narrow band only at the tip of the cell wall. The simplest method is to immerse the honeycomb material to a predetermined depth in a flat shallow container (bat) filled with adhesive.
