〔産業上の利用分野〕
本発明は住宅、倉庫等に使用するサンドイッチパネル、

性を具備した建築用パネルに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to sandwich panels used in houses, warehouses, etc.
In particular, it improves the adhesion between a foam that releases moisture such as condensed water during foam formation and a thin metal plate that does not allow such moisture to pass through, and has fire retardant, heat insulating, corrosion and mold resistant properties. It concerns the panel.
一般に、フェノールフオームを芯材とするサンドイッチ

体にフェノールフオームを介在したボード等があった。In general, sandwich-type panels with phenol foam as a core material have a structure in which one side is metal and the other side is sandwiched between flexible sheets, or a board in which phenol foam is integrally interposed between the sheets. Alternatively, there were boards in which phenol foam was interposed between a hard base material such as gypsum board and a sheet-like material.

水分が面材の裏面とフオーム形成途中の反応時間に介在
し、フオームの接着性を大幅に阻害して剥離を招く欠点
があった。[Problems to be Solved by the Invention] However, in this type of panel or board, when the phenol foam is mixed with a resol type phenol resin, a curing agent, and a foaming agent to form a foam between these face materials, condensation occurs during the reaction. Since 10 to 20% of water is released, this water is present between the back surface of the facing material and the reaction time during foam formation, which has the drawback of significantly inhibiting the adhesiveness of the foam and causing peeling.
なお、この縮合水は反応系において不可欠のものである
。また、フェノールフオームの反応系は発泡が始まると
急激であり、接着力の強いゲルタイムにマツチして面材
と接触させることが難しく面材の全面と均一に接着され
にくい不利があった。Note that this condensed water is essential in the reaction system. In addition, the reaction system of phenol foam has the disadvantage that foaming occurs rapidly once foaming begins, and it is difficult to match the gel time, which has a strong adhesive force, and bring it into contact with the facing material, making it difficult to adhere uniformly to the entire surface of the facing material.

ルを提案するものである。In order to eliminate such drawbacks, the present invention interposes a nonwoven fabric or a sheet-like material having a large number of through holes on at least one side of the face material and has water absorbency and flame retardancy, so that the phenol foam can be formed easily. The present invention proposes a construction panel that absorbs most of the condensed water, eliminates the decline in adhesive strength between the facing material and the foam, improves mechanical strength, fire resistance, heat insulation, and productivity, and is also inexpensive.

To further explain, the surface material 1 is made of a metal thin plate, such as a surface-treated steel plate, a steel plate plated with a zinc-nickel alloy, an aluminum/zinc alloy plated steel plate (product name: Galfan, Galvalume steel plate, Super Zinc), an aluminum plate, Metal plates (including flat plates and embossed plates) such as aluminum alloy plates, fluororesin-coated steel plates, copper plates, clad steel plates, and damping steel plates, stainless steel plates, flat titanium plates, or predetermined shapes by roll forming, press forming, etc. For example, Figure 3 (

ド系などの１種、または２種以上からなるものである。In particular, the surface of the backing material 2 that comes into contact with the core material 3 is made of resin such as polyethylene, polyurethane, polyester, or epoxy.
When the seed is laminated as a face material, the adhesive force with the core material 3 is strengthened. This is presumably because the resins adhere more easily to each other than to the surface of the other back material 2, and intermolecular bonds are more likely to act. In addition, the core material 3 is a phenol resin, particularly a substance formed from a resol type resin, a curing agent, and a foaming agent to form phenol foam (hereinafter simply referred to as foam), or a phenol foam obtained by using crude MDI in a phenol resin, or phenol foam. It also includes foams modified to cause the resin to react with other resins. The sheet-like material 4 absorbs condensed water during the formation of the foam 3, and the surface material 1
It is interposed between the back surface 1a of the foam 3 and the foam 3, and functions so that the adhesive force of the foam 3 can be maximized. In particular, if the sheet-like material 4 is a non-woven fabric and has a certain amount of bulk, the reactants of the foam 3 will come into contact with the surface material 1 near the gel time during the reaction before reaching the foam 3, and at the same time, the condensed water during the reaction will form on the sheet. Water is absorbed by the shaped material 4, and the foam 3 and the surface material can be brought into contact without impairing the adhesiveness of the reaction system. Note that the sheet-like material 4 has natural through-holes 5 in the case of non-woven fabric, and in other cases, through-holes 5 of an appropriate size.
For example, as shown in FIG. 2, a large number of holes are drilled. The sheet-like material 4 is mainly made of a flame-retardant and waterproof sheet material, or a sheet of water-absorbing material, which is impregnated or coated with a water-absorbing resin. The above-mentioned water-absorbing resins include (a) starch-based, (0) cellulose-based, and 09 synthetic resin-based, and (a) includes acrylonitrile grafted hydrolyzate,
Acrylic acid graft compound, (2)) is a graft polymer, carboxymethyl compound, ←→ is one or more of polyacrylate type, polyvinyl alcohol type, polyethylene oxide type, etc. .

キュアする。In Example 1, the surface material 1 (with embossment) - sheet material 4a - core material 3 - back material 2 - color steel plate (flat)
, Example 2 is surface material 1 (flat) - sheet material 4b
- core material 3 - sheet-like material 4b - back material 2, and the comparative example had a layered structure of surface material 1 (flat plate) - core material 3 - back material 2 (embossed). In addition, the manufacturing method is to place the surface material 1 on the lower mold,
Next, each component such as phenol resin is mixed and discharged on the back side of the facing material 1, and then the backing material 2 is placed, and an upper mold is placed on it, or a sheet material 4 is laid on the back side of the facing material 1. Then, after discharging the foam raw material, place the backing material 2, place the upper mold,
Cure.

が見られた。From the above results, in Example 1.2, the sheet-like material absorbs the condensed water released during the reaction and foaming of the phenol foam raw material, and also transitions from cream time to gel time while passing through the sheet-like material 4, and the surface It is thought that the contact was made under the best conditions since it came into contact with the material 1 and the backing material 2, and the adhesive strength increased. On the other hand, in the comparative example, the reaction was in the middle, but before the gel time was reached, and the condensed water was still being released.
Since it came into contact with the back of the backing material 1.2 under conditions such as dew condensation, the skin layer of the foam structure was thick and had varying densities. In addition, although all of Example 1.2 and Comparative Examples passed the fire retardancy test overall, Example 1.2 passed the sheet-like material 4.
Despite the intervention, I passed the exam. Furthermore, there was a difference in compressive strength.

The water-absorbing resin absorbs approximately 20% of the total weight of water released during reaction foaming, and no water is present on the contact surfaces between the reactant and the front and back materials. ■The reactant is delayed until the gel time, and then brought into contact with the front and back materials under favorable conditions, greatly improving adhesive strength. ■The foam structure is made more uniform and the mechanical strength is increased. ■It can be manufactured without much dependence on the state of the reaction mixture during production, making it easier to produce and reducing costs. It has the following characteristics.
