摩擦性の必要がないからである。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a vertical cross-sectional view of an endless melamine resin decorative board according to the present invention. In this drawing, an endless melamine resin decorative board 1 for a vertical plate has a pattern 2 made of a quick-setting melamine resin, and A long roll-shaped makeup in which the core 3 of the layer is made of a quick-setting phenol resin, and the bucca-4 is made of a fast-setting phenol resin or a fast-setting melamine resin. The thickness of the plate depends on the number of cores 3, or the basis weight of the base papers that make up the cores 3 and their resin impregnation amounts, and is preferably 0.2 mm to 0.8 mm, but is particularly limited. is not. Since these decorative boards are used for vertical boards, the overlay used for ordinary decorative boards is not necessary. In other words, the overlay plays a role of protecting the surface pattern when it is used on a work top such as a desk, a table, a sink, etc.
This is an essential layer for horizontal applications, but it is not necessary for abrasion resistance in vertical applications.

It is a resin adjusted to a condition of being cured in 0 seconds or less. In general, melamine resins have a fast curing property among condensed resins, but under the above curing conditions, a satisfactory surface condition cannot be obtained due to insufficient resin flow and gas generated by condensation. In the present invention, the above-mentioned drawbacks are improved, and it is a melamine resin having melamine and formaldehyde as main components, and partially alkyl etherified with alcohols or glycols and oxides, and further depending on the application. It contains modifiers such as urea, benzoguanamine, acetoguanamine, and paratoluenesulfonic acid amide.

販されていない。As described above, the endless melamine resin decorative plate for vertical plates according to the present invention is batch type 909 × 1818 mm (3 × 6) by a conventional multi-stage press machine.
Length) or 1212 × 2424 (4 × 8), which is obtained by manufacturing a melamine resin decorative sheet, but the length is endless, so the size in the length direction is free. Therefore, there are many advantages in terms of application. That is, when used for a wall surface or the like, the melamine resin decorative board of the conventional size has a seam because the length is limited, but the endless melamine resin decorative board of the present invention becomes a seamless single piece, and the design Is superior. When a thin melamine resin decorative board having a thickness of 0.6 mm or less is manufactured by a conventional multi-stage press, it is often not commercially available because it is often damaged during handling work due to its thinness and the yield is reduced.

FIG. 2 is an explanatory view showing the main part of the manufacturing process of the endless melamine resin decorative board of the present invention. In this drawing, a pattern-impregnated paper 2 impregnated with a fast-curing melamine resin, a fast-curing phenol resin. Each roll of core-impregnated paper 3 impregnated with, and packer-impregnated paper 4 impregnated with a fast-curing phenolic resin or a fast-curing melamine-based resin can be sequentially stacked on the impregnated paper unwinding device A from above. It is inserted into the attached continuous forming press machine B, and the continuous forming press machine B is composed of a heating drum 5, endless steel belts 6 and 7, and a pressurizing portion 8, and the endless steel belt is driven by the heating drum. The integrated impregnated paper inserted into the continuous molding press is sandwiched between the mirror-like steel belt 6 contacting the front side and the steel belt 7 contacting the back side. The upper and lower endless steel belts receive heat from the heating drum.

60 ° C is a good temperature, and this temperature depends on the grade of the obtained endless melamine resin decorative board. That is, in the case of producing an endless melamine resin decorative board for post forming, 140 to 150 ° C. is particularly preferable, and in the case of producing an endless melamine decorative board for a vertical plate, 150 to 150 ° C.
160 ° C. is preferred. Next, the applied pressure may be 10 to 30 kg / cm 2 by the tension applied to the endless steel belt and the pressure applied by the fluid in the pressurizing section 8. The material of the endless steel belt is hard stainless steel (SUS
In 304), the surface condition of the mirror-finished steel belt 6 having a thickness of 1.2 mm differs depending on the surface finish of the endless melamine resin decorative plate to be obtained. That is, when the matte product is obtained, the surface state of the mirror-like steel belt 6 is matte, and when the product is glossy, the surface condition of the mirror-like steel belt is glossy. The surface finish state of the steel belt on the back side is not particularly limited.

After that, the back surface is continuously sanded by the sander device D using the belt sander 10, and the endless melamine resin decorative board 1 is wound by the product winding device E. Here, a cutting machine such as a guillotine cutter, a rotary knife, or a tip saw may be inserted in the preceding step of the product winding device E to cut the product to an arbitrary length. That is, when the thickness of the decorative plate is 1.0 mm or more, it is difficult to wind it, so that the decorative plate is cut into a length according to the order in the market, loaded, packed and shipped. In the case of a scroll, the product is packed and shipped in a length that meets the market order.
