が、重量が増し、製造コストが嵩む。Of the above-mentioned conventional composite boards, a composite board in which both surfaces of a foamed phenolic resin are simply covered with a soft surface material such as paper or foil has a significantly higher strength than the foamed polystyrene resin or foamed polyurethane resin. A weak, light impact destroys the foamed resin inside. Further, when the end portion is cut and processed to make it a ceiling material, the foamed resin is too brittle and the end portion is missing. When a high density foamed phenol resin is used, the strength of the foamed resin increases, but the weight increases and the manufacturing cost increases.

ができない。The conventional plate-shaped honeycomb material is filled with foamed phenol resin in the voids, and both surfaces are covered with a surface material, which has excellent mechanical strength, but as a surface material or a honeycomb material, a flammable material such as graft paper is used. Since it is used, despite the fact that the phenol resin is flame-retardant, the surface material or the honeycomb material burns, and the flame-retardant property of the board is lost.
It cannot meet the standard as a flame-retardant or semi-combustible board.

特に長尺物を製造するのが困難である。Further, it is often the case that the honeycomb member is formed into a plate shape extending in the direction perpendicular to the direction of the voids, the voids of the honeycomb member are filled with a foamed resin, and both surfaces thereof are covered with a surface material to produce a composite heat insulating board. Is difficult to manufacture,
In particular, it is difficult to manufacture a long product.
従来の不燃性段ボールは断熱材を用いず、断熱効果が小

成してもよい。Next, the contents of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view of an example of the flame-retardant composite heat insulating board of the present invention. (6) is a flat liner made of flame-retardant paper, and the corrugated core paper (5) is attached between the liners (6) and (6) on both sides to form a single-layer double-sided corrugated board (7). . Columnar void parallel to the corrugated board surface between the core paper (5) and the liner (6)
Fill (2) with the expanded phenolic resin (3). Liner (6)
Does not consist of flame-retardant paper, but plain paper, and its liner
A flame-retardant surface material may be laminated on (6). Only the liner (6) and the core paper (5) on one side of the double-faced cardboard may be made of flame-retardant paper.

剤を介して積層すればよい。FIG. 2 shows a foamed phenolic resin (3) filled in the void (2) of a double-sided double-faced corrugated board (7) 'made of flame-retardant liner (6) and core paper (5). It is sectional drawing of another example of a flame-retardant composite heat insulation board. Fill the void (2) between the core paper (5) and the upper and lower surface liners (6) with the foamed phenolic resin (3), but leave a gap between the inner liner (6) 'and the core paper (5). (2)
However, it is not always necessary to fill the foamed phenolic resin, but in the case of obtaining a product in which all the voids are filled, if a single-layer corrugated board filled with the foamed phenolic resin (3) in advance is laminated with an adhesive. Good.

り過ぎる。As the flame-retardant paper used for the liner (6) and the core paper (5), ordinary flame-retardant treated paper, especially calcium carbonate paper, aluminum hydroxide paper is used. The flame-retardant paper used as the liner (6) is more preferably calcium carbonate paper or aluminum hydroxide paper mixed with glass fibers during papermaking. Those having a basis weight of 50 to 500 g / m 2 are preferable, and more preferably 100 to 300 g / m 2.
belongs to. When the basis weight of these flame-retardant papers is less than 50 g / m 2 , the reinforcing effect of the foamed phenolic resin (3) is small, and
If it exceeds 00 g / m 2 , the flame-retardant composite heat insulating board becomes too expensive.

である。The foamed phenolic resin (3) to be filled in the voids (2) is a mixture of a resole-type or benzylic ether-type liquid phenolic resin with a foaming agent, a foam stabilizer and a curing agent, which is used as the voids (2). And heat and foam. At this time, it is also possible to preliminarily mix, for example, a termite repellent or the like as an insect repellent in the foamed phenolic resin composition used.

(3)を充填することができる。To fill the foamed phenolic resin in the corrugated board voids (2), it is possible to inject the foamable liquid phenolic resin into the molded corrugated board voids (2) and heat and foam it. At the same time, it is preferable to fill the foamed phenol resin at the same time. That is, in the normal corrugated board manufacturing method, glue is applied to the corrugated corrugated corrugated corrugated corrugated corrugated corrugated sheet top with a glue roll, and a liner is placed on the corrugated corrugator roll. It is heated and bonded with, but instead of applying glue to the top of the corrugated core paper (5), apply the foamable phenol resin liquid to the adhesive surface of the liner (6) and step it in a corrugated form. When it is adhered to the core paper (5) and heated, the phenolic resin acts as an adhesive between the liner (6) and the core paper (5), and also between the core paper (5) and the liner (6). Foam in the voids. As a result, at the same time as the production of corrugated board, the foamed phenolic resin is filled
(3) can be filled.

(3)が段ボールにより補強されているため、ボードとし
て圧縮強度及び曲げ強度が大きく、耐衝撃性も向上し、
発泡フェノール樹脂ボードの欠点を大きく改善する。The flame-retardant composite insulation board of the present invention is a foamed phenolic resin.
Since (3) is reinforced with corrugated cardboard, the board has high compressive strength and bending strength and improved impact resistance,
It greatly improves the drawbacks of expanded phenolic resin boards.

The bending strength and the presence or absence of chips during processing of the edges were examined. Moreover, according to the flame retardancy test method of JIS A1321, the temperature time area exceeding the standard temperature curve
The tdθ, the smoke emission coefficient C A per unit area, and the afterflame time were obtained. The results are shown in Table 1 as Examples 1 to 5.
Tdθ less 100 ° C. seconds of the flame retardancy test value, C A is 6
If the afterflame time is 0 or less and the afterflame time is 30 seconds or less, the flame-retardant second grade is passed.
