本発明は建築、Ill物の外装材として有用な建築用断
熱t(以下、単に断熱板という)の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a thermal insulating material for buildings (hereinafter simply referred to as a thermal insulating board) useful as an exterior material for buildings and objects.
特にこの断熱板が防火構造用部材として使用でき、かつ
、生産性にすぐれると共K、コストダウンをも図り得る
断熱板に係る。In particular, the present invention relates to a heat insulating board that can be used as a fireproof structural member, has excellent productivity, and can also reduce costs.

物側端から漏洩し、断熱板背面、および型材を汚す。Conventional manufacturing methods for this type of insulation board include distributing refractories uniformly throughout the foam structure of the core insulation material, layering flat sheet materials on top of the foam, and then forming and curing them in a curing oven, etc. was taken. However, when a heat insulating board is manufactured by this type of manufacturing method, there are disadvantages in that the following points are lacking. That is, (1) It is difficult to uniformly mix and discharge the foamed synthetic resin and refractory material, which are the raw materials for the heat insulating core material, and furthermore, the foamed structure becomes rough. ■If the foam structure of the insulation core material is damaged, the expansion ratio and mechanical strength will decrease. ■■、■
This increases the amount of foamed synthetic resin used, leading to an increase in costs. - Foamed synthetic resin leaks from the side edge of the sheet material during foam molding, staining the back surface of the insulation board and the mold material.

多い。これは型材に発泡途中の合成樹脂原料が直接に接
触するためである。すなわち、これは加熱されている型
材の現在の温度と発泡途中の原料の温度との間にズレが
生ずるためである。In other words, when a flat sheet is formed into a foam, the foaming pressure of the foam is used to mold the sheet to fit the mold material, so even a slight deviation will cause the above-mentioned results. (2) In particular, in the case of a cross-sectional shape that has a bulge protruding from the recess of the metal hoop material, the desired cross-sectional shape is very often not achieved because the method involves simultaneously removing the side edges of the female part and releasing the shape. This is because the synthetic resin raw material in the process of foaming comes into direct contact with the mold material. That is, this is because a gap occurs between the current temperature of the mold material being heated and the temperature of the raw material that is being foamed.

熱板の製造方法を提案するものである。In order to eliminate such drawbacks, the present invention laminates fire-resistant aggregate-containing foamed synthetic resin raw material only in the female connection structure part, which is the weakest point in the fireproof structure, and uses foamed synthetic resin alone in the other parts. At the same time, the formed sheet-like material is laminated on the raw material, and the metal hoop material and the sheet-like material are fixed by the self-adhesive property during foaming of the foamed synthetic resin raw material. The present invention proposes a method for manufacturing a heat insulating board that has fire resistance, heat insulation properties, and mechanical strength, and that does not contaminate the heat insulating board or equipment due to resin leaking outside due to the foaming pressure during manufacturing.

The hoop material is continuously fed out and fed to the forming machine 3, and is bent into the cross-sectional shape shown in FIG. 2(a). In other words, FIG. A bent portion 4.5 of a male and female type connection structure is provided, and a recessed portion 6 is formed between the bent portions 4.5. This hoop material 1 is fed to a preheater 7, where it is heated to about 40 to 90 C and transported to the next process.

のに役立つものである。1O is a so-called aggregate-containing foamed synthetic resin raw material 13, which is obtained by mixing fire-resistant aggregate 11 and foamed synthetic resin 12 in a mixer, on the back surface 5a of the bent portion 5 of the hoop material 1 as shown in FIG. It is preferable that the discharge range S is not the entire back surface of the back surface 5a, but an area that is about 2 to 5111 degrees inward from the tip. This is to facilitate the installation work and to provide a safety margin so that a part of the foamed synthetic resin raw material 12 does not go around to the surface 5C via the tip 5b of the bent part 5. The aggregate 11 suppresses its fluidity and helps prevent the raw material 12 from leaking to the outside.

Reference numeral 22 is a cutter for cutting a heat insulating plate fed from the outlet of the curing oven 16 and having a cross section as shown in FIG. 4 into a predetermined size. As a result, as shown in FIG. 4, the heat insulating board has a foam 23 portion made only of foamed synthetic resin and a foam containing aggregate, a so-called fireproof layer 24, which are integrally formed.
Moreover, the hoop material 1 and the sheet-like material 1B are stuck together due to their self-adhesive properties during foaming of the foamed synthetic resin raw material.
