ることによって樹脂発泡体複合板が得られる。A common method for continuously manufacturing composite boards is to discharge a resin mixture onto the bottom material that is being continuously transported.
A top surface material is continuously and laminatedly supplied on top of this resin mixture to form a continuous laminated body. Next, this laminated continuum is passed through a curing furnace and heated while being pressed from the top and bottom surfaces, thereby foaming and hardening the layer of the resin mixture to a predetermined thickness, and the laminated continuum coming out of the curing furnace to a predetermined size. A resin foam composite board is obtained by cutting.

に脆いために使用方法が難しかった。However, among resin foams that serve as core materials, phenolic resin foams have excellent properties such as heat resistance, flammability, and low smoke emission, but compared to other resin foams, phenolic resin foams have very low performance. It was difficult to use because it was brittle.

化合物。In order to solve the drawbacks of phenolic resin foam, a new foamable phenolic resin mixture has been proposed by the same applicant as the present application (Japanese Patent Application Laid-Open No. 115-1989).
No. 20). This foamable phenolic resin mixture is a benzylic ether type phenolic resin and a polyisocyanate compound.

械的物性を有するフェノール樹脂発泡体が得られる。It consists of an aromatic sulfonic acid compound, water, a blowing agent, and a foam stabilizer, and by foaming and curing this mixture, a phenolic resin foam having good mechanical properties can be obtained.

炉の温度を６０〜８０℃として行なった。<Problems to be Solved by the Invention> The present inventors manufactured a phenolic resin foam composite board using the above-mentioned foamable phenolic resin mixture. For this production, the general method as described above was employed, and the temperature of the curing furnace was set at 60 to 80°C.

着力が必ずしも十分でないものもおった。When the composite board thus obtained was examined, it was found that the phenolic resin foam layer had good mechanical properties, but there were some areas where the foam was not uniformly foamed, and the uniformity of density was poor. I found out that there was some problem. Further, although the above-mentioned foamable phenolic resin mixture has good self-adhesive strength with various face materials, the adhesive strength of some face materials with the foam may not necessarily be sufficient depending on the conditions.

できることを見出し、既に特許出願を行なった（特願昭
６０−２０００８４号）。Therefore, the inventors of the present invention improved the conventional manufacturing equipment and changed the conventional curing furnace that performs both foaming and curing of the resin mixed liquid layer.
Completely separated into two chambers: a foaming chamber for foaming the resin mixed liquid layer and a curing chamber for curing the foamed layer.
By providing optimal conditions for foaming in the foaming chamber and optimal conditions for curing in the curing chamber, the foam layer foams uniformly, has excellent density uniformity, and has a sufficient bond between the face material and the foam. It was discovered that a phenolic resin foam composite board with adhesive properties could be manufactured, and a patent application has already been filed (Japanese Patent Application No. 1984-200084).

な場合には、この隔り部分で発泡が起ると発泡体自身が
面材から剥離してしまう現象もみられる。However, in the improved device related to the above-mentioned earlier application,
For example, temperature conditions can be maintained at the optimal temperature for each of the foaming chamber and curing chamber, but since the foaming chamber and curing chamber are placed side by side with fixed dimensions, the foaming time and curing time in each chamber are Each is uniquely determined by the line speed at which the stacked continuous body is conveyed through each chamber. As a result, there is a disadvantage in that production management to ensure foaming in the foaming chamber up to around the rice time (the time required for the foam to reach its maximum height) becomes complicated. Particularly in cases where there is a gap between the foaming chamber and the curing chamber, if foaming occurs in this gap, the foam itself may peel off from the facing material.

してなされたものである。Therefore, the present invention significantly improves the device according to the above-mentioned prior application, and can provide more appropriate conditions to the foaming chamber and the curing chamber, respectively, thereby producing a foam layer of uniform foaming and uniform density. The purpose of this invention is to provide an apparatus that can produce a phenolic resin foam composite board with improved productivity and excellent adhesion between the face material and the foam.

The inventors have completed this invention by discovering that the above object can be achieved by dividing the inside of the curing furnace into a foaming area and a curing area by a horizontally movable partition, instead of having a chamber and a curing chamber. It is.

It is characterized by being divided into a foaming zone where the resin mixture layer is foamed, and a curing zone where the laminated continuous body coming out of the foaming zone is heated to a temperature of 50 to 100°C to harden the foam layer of the resin mixture liquid. That is.

Not only can the optimal temperature for foaming the foamable phenolic resin mixture and the optimal temperature for curing after foaming be provided in each zone, but by moving the partition horizontally, the foaming area and Since the length of the curing zone can be changed, the foaming time and curing time can be adjusted without changing the line speed. Therefore, foaming can be carried out in the foaming region for an optimum period of time up to just before rice time at the optimum foaming temperature within the temperature range of 20 to 80°C, and the thus foamed phenolic resin foam layer can be foamed at a temperature of 50 to 80°C. It becomes possible to efficiently cure in a curing region having an optimum curing temperature within a range of 100°C.

り高いと発泡体中に亀裂を発生する傾向がみられる。If the foaming temperature is lower than 20°C, the rise time will be very long, and if it is higher than 80°C, the foaming rate cannot be controlled, uniform foaming will not be achieved, and density uniformity will deteriorate. On the other hand, if the curing temperature is lower than 50°C, curing will not be sufficient and the mechanical properties of the foam will be poor. Furthermore, if the temperature is higher than 100°C, there is a tendency for cracks to occur in the foam.

表にまとめて示す。Using the equipment shown in the attached drawings, composite plates of various sizes were manufactured using colored steel plates as the bottom material and aluminum foil-covered kraft paper as the top material. At this time, the amount of charged foaming phenolic resin mixture was 39 kQ/Tl13, the line speed was 15 m/ll1in, and the total length of the curing furnace was 3
5m, the suppression conveyance device inside the curing furnace has multiple roller parts 3Hn
and a belt conveyor section of 4 m. In addition, by moving the partition in the curing furnace in the horizontal direction, adjustment was made to provide an optimal foaming region length, that is, a predetermined foaming time, depending on the dimensions of the composite plate. Composite plate dimensions and manufacturing conditions are the first
