本考案は防湿、防水性にすぐれ、基体に対して
接着性がすぐれ、かつ硬質合成樹脂発泡断熱板製
造時に使用し易く、製造された断熱板の反りも少
ない硬質合成樹脂発泡断熱板用表面材に関する。[Detailed description of the invention] This invention is a hard synthetic resin that has excellent moisture and waterproof properties, has excellent adhesion to the substrate, is easy to use when manufacturing hard synthetic resin foam insulation boards, and has less warpage in the manufactured insulation boards. This invention relates to a surface material for resin foam insulation boards.

硬質合成樹脂発泡断熱板はその使用用途に大きな
制限を受けるものであつた。 However, the hard synthetic resin foam used as the core material itself has moisture absorption and moisture permeability, although only slightly, so when constructing a synthetic resin foam insulation board, it was necessary to form a moisture-proof and waterproof layer. .
Conventionally, this moisture-proof and waterproof layer was mainly formed from a polyolefin-based synthetic resin film. However, on the other hand, the surface does not absorb moisture and is inert, so adhesives, especially synthetic resins with water-based adhesives such as cement adhesives, gypsum adhesives, and water glass adhesives. It was impossible to bond foam insulation boards together or to adhere them to other building materials or building frames, and it was also possible to bond them together with concrete when pouring concrete. Therefore, the conventional rigid synthetic resin foam heat insulating board provided with a moisture-proof and waterproof layer has been subject to severe limitations in its usage.

As disclosed in No. 54-171493, a surface material was developed in which asbestos paper and a flexible sheet were adhered with an adhesive, and a moisture-proof synthetic resin film was adhesively laminated on the surface of the flexible sheet. It was done.

た。 However, the surface material disclosed in Utility Model Application Publication No. 54-171493 has kraft paper interposed as a reinforcing material between the asbestos paper and the moisture-proof synthetic resin film, so the tensile strength of the surface material is high, and the long surface While stretching the material, the foamable synthetic resin raw material is applied onto the surface material, and while it is foamed, it is suitable for obtaining a heat insulating board with the surface material adhered to it. There were major drawbacks such as dimensional changes in the kraft paper and delamination of the kraft paper due to absorbed moisture.

きな欠点があつた。 In addition, in order to solve the problem of delamination, a surface material made by laminating only asbestos paper and moisture-proof synthetic resin film without using kraft paper was used, but since there was no reinforcing material, the tensile strength was low. , it was unsuitable for continuous production of insulation boards. Furthermore, a surface material in which nonwoven fabric was used as a bonding layer instead of asbestos paper, and kraft paper and moisture-proof synthetic resin film were sequentially adhesively laminated was used, but although it had high tensile strength and could withstand continuous production of insulation boards, it As expected, the kraft paper had a major drawback of moisture absorption and delamination due to water absorption.

のが好ましい。 That is, the surface material 1 for a hard synthetic resin foam insulation board of the present invention is a surface material used when a hard synthetic resin foam raw material is applied onto the surface material and foamed to continuously produce a hard synthetic resin foam insulation board. It is made by adhesively laminating a moisture-proof synthetic resin film with the entire nonwoven fabric embedded on one side of asbestos paper containing 50% or more asbestos. Asbestos paper 2 has a basis weight of 80
A lightweight material of g/m 3 or more is sufficient, and the pulp content is
Preferably, the content is 10% or less. Pulp content is 10%
If the temperature exceeds the above, if concrete, mortar, plaster, etc. are applied to the asbestos paper 2 side, or if a water-based adhesive is used, it will easily absorb moisture and cause expansion and contraction, so it cannot be used as a surface material for the insulation board. This is undesirable as it causes the insulation board to warp. Also, the basis weight
If it is less than 80 g/m 2 , the strength of the asbestos paper is so low that it may break during processing or cause the heat insulating board to warp, which is not preferable. In order to improve strength and reduce warpage, it is preferable to have a basis weight of 100 g/m 3 or more.

布が使用できる。 The nonwoven fabric 3 is preferably lightweight and coarse-grained with a basis weight of 50 g/m 2 or less, so that the moisture-proof synthetic resin film 4 can sufficiently penetrate into the holes of the nonwoven fabric 3 and the nonwoven fabric 3 can be easily embedded and integrated into the film 4. . As the nonwoven fabric 3, a synthetic fiber nonwoven fabric or a nonwoven fabric mixed with glass or synthetic fibers can be used.

は殆ど変りがなく、実用に供せる。 The moisture-proof synthetic resin film 4 and the nonwoven fabric 3 must be integrated so that the nonwoven fabric 3 is substantially buried in the moisture-proof synthetic resin film 4. The surface of the heat insulating board of the moisture-proof synthetic resin film 4 in contact with the hard synthetic resin foam core material 5 is a synthetic resin surface with no exposed nonwoven fabric 3, but when the foamable synthetic resin raw material is applied onto this surface, This is preferable in terms of coating uniformity and prevention of seepage, and also increases the permeation resistance value against moisture, but even if the nonwoven fabric 3 is slightly exposed, there is practically no change, and it can be used for practical purposes.

It is suitable and can be manufactured efficiently without cutting the surface material during manufacturing.Also, it does not stretch even when the surface material is stretched, so the surface material of the heat insulating board to which the surface material is adhesively laminated can be easily manufactured by the tension during the manufacturing process. Since there is no residual restoring force due to elongation and the dimensional stability is good, the heat insulating board is extremely difficult to warp.
