一に分散させることは極めて困難であつた。 Conventionally, when building insulation materials such as insulation boards and decorative panels are made of foamed resin such as urethane foam resin alone, there are drawbacks such as dimensional instability due to primary shrinkage after molding of the construction insulation material. When this architectural insulation material is actually used, it expands and contracts due to temperature differences, and in the winter, gaps may appear at the joints of the construction insulation material, and in the summer, the construction insulation material expands and the joints become tight. It had the drawback of being exciting. Therefore, attempts have been made to mix inorganic reinforcing fibers into architectural insulation materials in order to improve this dimensional change, but it has been extremely difficult to uniformly disperse these inorganic reinforcing fibers into architectural insulation materials.

用断熱材を取り出す。 Hereinafter, the present invention will first be described in detail with reference to illustrated embodiments. The inorganic reinforcing fiber 1 is, for example, something like glass fiber, and is fluffed into flakes. As the foamed resin 2, for example, a urethane foamed resin is used, and one that undergoes an exothermic reaction at 80 to 100°C is optimal. As the adhesive, for example, a hot melt adhesive is used, and its melting temperature is optimally 50 to 80°C. As the mold 3, for example, in the case of continuous molding, a movable mold 3a disposed on the caterpillar 6 of the double conveyor 5 is used, and in the case of batch molding, a fixed mold is used. In this embodiment, a case where a double conveyor 5 is used will be explained. The double conveyor 5 is composed of an upper caterpillar 6a and a lower caterpillar 6b, and a movable mold 3a is continuously disposed on the outer peripheral surface of both caterpillars 6a, 6b. Furthermore, two release paper supply reels 7 are arranged above and below on the entrance side of the double conveyor 5 (on the right side in Figure 1), and on the exit side of the double conveyor 5 (on the left side in Figure 1). 2 up and down
A release paper take-up reel 8 is provided, and the release paper 9 supplied from the release paper supply reel 7 passes through the movable molds 3a of the upper and lower caterpillars 6a and 6b to the release paper take-up reel 8. It is designed to be rolled up. The inorganic reinforcing fiber 1 fluffed into flakes is the first
As shown in the figure, it is supplied to the double conveyor 5 from the entrance side. This inorganic reinforcing fiber 1 is a double conveyor 5
Before being sent to the machine, adhesive has already been applied to fix the flaky fuzz. When the inorganic reinforcing fibers 1 are supplied to the double conveyor 5, the foamed resin supply device 10 disposed above the inlet side of the lower caterpillar 6b supplies the foamed resin 2, and the movable molds 3a of the upper and lower caterpillars 6a and 6b are supplied. It foams in between. At this time, an exothermic reaction of about 80 to 100° C. occurs, so that the adhesive fixing the fluff of the inorganic reinforcing fibers 1 is loosened, and the inorganic reinforcing fibers 1 are uniformly dispersed within the foamed resin 2. Moreover, since the foamed resin 2 is sandwiched from above and below with release paper 9 at this time, the surface will not adhere to the movable mold 3a and become rough. When the foaming reaction of the foamed resin 2 is completed and it hardens, it is pulled out from the exit side of the double conveyor 5, and then cut into a certain size to become a heat insulating material for construction. In the case of batch molding, although not shown, the inorganic reinforcing fibers 1 with fluff fixed with adhesive are stretched in a fixed mold, and then the foamed resin 2
is filled into a fixed mold and foamed, and after the foaming reaction is completed (usually after 5 minutes or more) the architectural insulation material is taken out from the fixed mold.

か壁内に配設して使用されるものである。 In the case of the present combined invention, as shown in FIG. 3, pearlite grains 4 are uniformly sprinkled on fluffed inorganic reinforcing fibers 1, and an adhesive is sprinkled on top of the fluffed inorganic reinforcing fibers 1 to form the inorganic reinforcing fibers 1 together with the pearlite grains 4. The fluff is fixed and fed to a double conveyor 5. In this way, during the exothermic reaction of the foamed resin 2, a large amount of pearlite particles 4 will be uniformly dispersed in the foamed resin 2 together with the inorganic reinforcing fibers 1, resulting in a lightweight, strong, flame-retardant architectural insulation material. Become. Furthermore, the strength can be dramatically improved by pasting paper, plastic sheets, aluminum foil, plywood, or metal plates on both sides of the foamed resin 2. Architectural heat insulating materials formed in this manner are used by being placed on the floors, ceilings, and walls of houses.

きるという利点がある。 As mentioned above, the present invention supplies inorganic reinforcing fibers with fluff fixed with adhesive into a mold,
Then, a foamed resin that reacts at a temperature higher than the melting temperature of the adhesive is injected into the mold and allowed to foam and harden. During the exothermic reaction of the foamed resin, the adhesive is heated and loosened, causing the inorganic reinforcing fibers to fluff. This has the advantage that the fluffy inorganic reinforcing fibers prevent expansion and contraction of the foamed resin due to temperature differences, eliminating dimensional changes in the thermal insulation material for buildings due to temperature differences. In addition, perlite grains are uniformly dispersed in the fluffed inorganic reinforcing fibers, and an adhesive is sprayed to fix the pearlite grains and fluff together, and the inorganic reinforcing fibers are placed in a mold, and the above adhesive is applied to the fluffed inorganic reinforcing fibers. The foamed resin, which foams at a temperature higher than the melting temperature of As a result, the inorganic reinforcing fiber compensates for the decrease in the bending strength of the architectural insulation material due to the inclusion of pearlite particles, creating an architectural insulation material with excellent bending strength and flame retardancy due to the pearlite particles. The advantage is that it can be done.
