Conventionally, various efforts have been made to give transparent plastic plate-shaped bodies a design quality. One of them is a printed transparent synthetic resin film laminated on an extruded resin plate with the printed side facing inside. Specifically, a product in which a biaxially stretched polystyrene film and an extruded polystyrene plate are laminated with a printed pattern interposed therebetween is commercially available. However, since this material is made of polystyrene, it has poor weather resistance and cannot withstand long-term outdoor use. Therefore, it is expected that a similar type of decorative board using polymethyl methacrylate resin (hereinafter referred to as acrylic resin), which is known to have weather resistance, will be developed and put on the market.

It consists of a copolymerization of 85% and 1% to 15% of methyl acrylate. The purpose of copolymerizing methyl acrylate is to suppress thermal decomposition during melt molding and to provide good fluidity. In addition, methyl ester is used as the acrylic acid alkyl ester for copolymerization to methyl methacrylate because it can be heated without losing the original characteristics of polymethyl methacrylate resin, such as transparency and surface gloss. This is because it provides resistance to decomposition and good fluidity.

イルムが剥離する現象の有無・程度で判断した。 By the way, when thermally adhering an acrylic resin film to the melt-extruded plate made of the above-mentioned molding acrylic resin, it is known to those skilled in the art that a film made of an acrylic resin having the same copolymer composition as the extruded plate is used as the film. This is the most common-sense choice I can think of. This is because, as common knowledge in chemistry, similar things have good compatibility. However,
In the course of various experiments conducted by the present inventors leading to the present invention, it was discovered that an acrylic resin film composed of the above-mentioned composition for molding had extremely poor thermal adhesion to a melt-extruded plate, especially when printing ink was present between the plate and the film. In this case, it was found that it was almost impossible to produce products with marketability. The adhesion was evaluated by determining whether or not the film peeled off at the cut end when the laminate was cut using an appropriate means such as a plastic saw or a plastic cutter.

This is an acrylic resin decorative board that is laminated through layers, and in order to obtain a good laminated acrylic resin decorative board, the acrylic resin film must have a special resin composition that is different from the resin composition of the extruded acrylic resin board. Based on the technical basis that it must be used.

刷法によつてなされる。 The present invention will be explained below with reference to the drawings. FIG. 1 shows an enlarged sectional view of one embodiment of the acrylic resin decorative board of the present invention. 1 is a plate-shaped extrusion molded body made of a copolymer resin of methyl methacrylate and acrylic acid methyl ester. 2 is a film made of a copolymer resin of methyl methacrylate and n-butyl acrylate.
3 is a printing ink layer, and the plate-shaped extrusion molded body 1 and the film 2 are laminated via the printing ink layer 3. The copolymer composition of the copolymer of methyl methacrylate and acrylic acid methyl ester in No. 1 is 85 to 95 weight percent of the former and 15 to 5 weight percent of the latter, and is commercially available as a methacrylic resin for molding from a resin manufacturer. It is. 2
In the copolymer of methyl methacrylate and n-butyl acrylate, it is preferable that the former be 65 to 95% by weight and the latter be 35 to 5% by weight, but more preferably the former be 70% by weight.
~85% by weight, the latter 30-15% by weight. The most preferred ratio is around 75:25 weight percent. If the ratio of n-butyl acrylic acid ester is too high, the transparency, which is a feature of polymethyl methacrylate resin, will be lost, which is not preferable. On the other hand, if the ratio is low, the film formability will deteriorate, which is not preferable.
The film is preferably formed by an inflation method under the lowest possible stretching conditions, and preferably has a heat shrinkage force of 5 kg/cm 2 or less. A film with a high heat shrinkage force is not preferable because the film will shrink when the extrusion molded product and the film are thermally bonded. Here, the thickness of one plate-shaped extrusion molded product is 0.5 m/m to 10 m/m, preferably 2 to 6 m/m. The thickness of the film No. 2 is preferably 30 to 200 microns. The printing ink layer 3 is preferably made of an ink with as high weather resistance as possible. The weather resistance of an ink is determined by the weather resistance of the pigments and resins used, and the formulation of these generally must depend on the know-how of the ink manufacturer. In particular, it must meet the general requirements for an ink, such as being transparent, having a beautiful color, and having good suitability for printing on film, and must also have good weather resistance, so this selection was made after thorough basic testing. There must be.
If there are concerns about the weather resistance of the ink, the ink layer can be protected from ultraviolet rays by incorporating an ultraviolet absorber into the copolymer resin that constitutes the extruded plate and film. . The printing layer is formed by gravure printing on the surface of the film.
This is done by offset printing, flexographic printing or silk printing.

化粧板の一例の拡大断面図を示すものである。 To manufacture the acrylic resin decorative board of the present invention,
While extruding the plate-shaped extrusion molded product using an extruder, films having a printed layer are pasted together with the printed side facing inside to form a laminate, and then this laminate is passed between two rolls. This ensures perfect lamination adhesion. By providing an appropriate pattern of embossing on one or both surfaces of the roll, an acrylic resin decorative board with an embossed pattern can be obtained. FIG. 2 shows an enlarged sectional view of an example of an acrylic resin decorative board obtained by passing the laminate between two embossing rolls.

The composition of this acrylic resin film was a copolymer of 76 weight percent methyl methacrylate and 24 weight percent n-butyl acrylate. Additionally, this film has an ultraviolet absorber incorporated into it and has an ultraviolet blocking function. The heat shrinkage stress of the film was 3 to 4 Kg/cm 2 . An acrylic resin consisting of a copolymer of 95% by weight of methyl methacrylate and 5% by weight of acrylic acid methyl ester and containing 0.1% by weight of an ultraviolet absorber was extruded into
The film was extruded to a width of m/m, and the film was placed so that the printed surface faced the extruded plate.

An acrylic resin decorative board was manufactured under the following conditions. The obtained acrylic resin decorative board showed peeling of the film at the cut end, and could be easily peeled off by hand. This film is a biaxially stretched film with a heat shrinkage stress of 15 Kg/cm 2 in both the vertical and horizontal directions before lamination. Therefore, there was a phenomenon in which the film caused some heat shrinkage during lamination and the printed pattern was slightly distorted.
