本発明は表面に仕上塗装とか化粧シートによる
ラミネート処理が可能なウレタン樹脂発泡板の表
面処理方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for surface treatment of a urethane resin foam board, which allows the surface to be subjected to finish coating or lamination with a decorative sheet.
元来ウレタン樹脂発泡板は断熱性、保温性及び
遮音性に優れ、しかも軽量であるから建材として
最適なものであることは自明であるが、ウレタン
樹脂発泡板は独立気泡体で全く通気性を有しない
ので、その表面に例えば塩化ビニル樹脂シートを
貼着しようとしても接着剤が硬化されず、従つて
通気性のないシートでラミネートすることは不可
能である。 It is obvious that urethane resin foam board is ideal as a building material because it has excellent heat insulation, heat retention, and sound insulation properties, and is also lightweight, but urethane resin foam board is a closed cell structure and has no breathability at all. Therefore, even if an attempt is made to attach a vinyl chloride resin sheet to the surface, the adhesive will not harden, and therefore it is impossible to laminate with a non-air permeable sheet.
本発明はこのようなウレタン樹脂発泡板の欠点

いて説明すると下記の通りである。 The present invention aims to eliminate such drawbacks of the urethane resin foam board and provide a board material ideal as a decorative board for construction, and one embodiment thereof will be described below based on the drawings.

下層の発泡層５を露出させない場合もある。 After sanding both the front and back sides of the urethane resin foam board 1 to make it a substantially smooth surface, a 0.25 mm thick glass nonwoven fabric 2 is attached to both the front and back sides using an acrylic/ethylene adhesive as shown in FIG. . In this case, the glass nonwoven fabric 2 is polymerized after volatilizing the solvent of the adhesive to some extent and leaving it in a semi-dry state. After the adhesive has completely dried, as shown in Figure 2, the foamable phenolic resin liquid 3 is uniformly applied to the glass nonwoven fabric 2 on the front side using a flow coater at a coating amount of 80 to 100 g/m2. It is allowed to sufficiently penetrate into the glass nonwoven fabric 2 to bring the glass nonwoven fabric 2 into a wet state. At this time, the phenol resin liquid 3 is
The thickness h 1 to the top surface of is approximately 0.5 mm. Subsequently, this was passed through a tunnel-type heating furnace with an internal temperature of 100°C for 7 minutes to foam and harden the phenolic resin liquid 3, thereby forming a phenolic resin foam layer 4 having an uneven upper layer as shown in FIG. A phenolic resin foam layer 5 in which glass fibers are mixed in the lower layer is formed. At this time, the thickness h2 of the entire foam layer including the glass nonwoven fabric 2 was approximately 2.0 mm. Finally, the upper phenolic resin foam layer 4 is sanded to make the surface smooth. In this case, as shown in Fig. 4, almost the entire upper foam layer 4 is removed to expose the lower foam layer 5 (thickness h3 is about 0.5 mm) on the surface; Remove until 4 is smooth,
The lower foam layer 5 may not be exposed.

のセンイを毛羽立てる方法もある。 In the above example, the glass nonwoven fabric was attached to the front and back sides of the urethane resin foam board using an adhesive.
When molding a urethane resin foam board, glass nonwoven fabrics are sometimes layered on the front and back sides and attached at the same time as the molding. Furthermore, in order to make the lifting of the glass fibers on the phenolic resin foam layer more noticeable, there is also a method of fluffing the fibers of the glass nonwoven fabric in advance.

とができるのである。 In this way, the method for surface treatment of a urethane resin foam board according to the present invention forms an open cell type phenolic resin foam layer on the surface of a single cell type urethane resin foam board, so it is possible to use a general paint finish or a non-porous chloride resin foam layer. A laminated finish such as a vinyl sheet can be applied, and although this phenolic resin foam layer forms relatively large irregularities on the surface, the air bubbles are small.
Moreover, since it is soft, it can be easily smoothed by grinding.

を形成することができるのである。 In particular, in the surface treatment method according to the present invention, a glass nonwoven fabric is pasted on the front and back sides of a urethane resin foam board, and then a phenolic resin foam layer is formed on the front nonwoven fabric. There is no risk of warping. In addition, since the foamable phenol resin liquid is completely permeated into the glass nonwoven fabric to make it wet, and then the resin liquid is foamed, the connections between the glass fibers are broken as the resin liquid foams, and the bonds within the foamed layer are broken. A foam layer is formed at the bottom where glass fibers are mixed and dispersed while floating, so by grinding and smoothing the uneven foam layer in the upper layer, it is possible to give the surface of the urethane resin foam board an appropriate amount of elasticity. Therefore, it is possible to form a tough film while maintaining the same properties.
