この発明は広幅タイプの断熱用板の製造方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a wide type insulation board.
従来、浴室用の内装建材として第１図に示すよ

れた断熱用板３を製造することが行われている。 Conventionally, as shown in FIG. 1, foamable urethane resin 2 is injected into a grooved rib 1 made of vinyl chloride resin and foamed and hardened to produce a heat insulating board 3 with excellent heat insulating properties as an interior building material for bathrooms. things are being done.
ところが、この断熱用板３の幅の広いものを得

じるという問題があつた。 However, when trying to obtain a wide insulation board 3, the urethane resin side shrinks during and after the foam curing treatment of the foamable urethane resin 2, and warps in the width direction as shown in FIG. There was a problem that this occurred.
したがつて、この発明の目的は、幅方向に反り

供することである。 Therefore, an object of the present invention is to provide a method for manufacturing a wide type insulation board that does not warp in the width direction.

８側の中央部が凸状に変形され、その湾曲状態で
発泡性ウレタン樹脂８が発泡硬化処理される。 An embodiment of this invention will be described based on FIGS. 3 and 4. That is, as shown in FIG. 3, a groove-shaped rib 6 made of vinyl chloride resin is supplied onto the lower conveyor 5 of the double conveyor 4 provided in close proximity to the upper and lower stages, with the groove facing upward.
Then, foamable urethane resin 8 is injected into the groove from a resin injection machine 7 provided above, and then carried into the double conveyor 4 for foaming and curing treatment.
At this time, the conveyance surfaces of the upper and lower conveyors 9 and 5 forming the double conveyor 4 are each formed of a mold consisting of an upper caterpillar 10 and a lower caterpillar 11 as shown in FIG. The central part of the lower caterpillar 11 forms a concave surface, and the central part of the lower caterpillar 11 forms a convex surface, so that the rib 6 carried in between has a convex central part on the side of the foamable urethane resin 8 injected into the groove. The foamable urethane resin 8 is deformed into a shape, and the foamable urethane resin 8 is foamed and hardened in the curved state.
そして、このようにして形成された断熱用板

平状の板状体となるのである。 When the heat insulating board thus formed is cooled to room temperature after the foaming hardening process, the foamed urethane resin shrinks and becomes a flat plate without warping.

ができた。 The degree of curvature of this mold varies depending on the constituent components of the foamable resin composition, the material of the rib 6, its width, the depth of the groove, etc. In this example, the width of the rib 6 is 30 cm, and the width of the rib 6 is 30 cm. As a result of setting the height of the curved portion to 2 mm, it was possible to obtain an excellent heat insulating board without warping.

がある。 As described above, the method for manufacturing a heat insulating board of the present invention includes injecting a foamable resin composition into the grooves of a channel member,
Because the foaming and curing process is performed with the central part curved toward the foamable resin composition side, it is possible to obtain a wide insulation board that does not warp in the width direction, increasing the efficiency of construction on wide wall surfaces. It has the effect of being able to.
