In addition, vinyl chloride resins having practically well-balanced properties in mechanical strength and durability have been widely used. However, vinyl chloride resins generally contain a plasticizer in order to improve moldability, which migrates and adversely affects other resinous materials, for example, causes cracks, causes a peeling phenomenon. Sometimes its use has been restricted. In recent years, it has been pointed out that vinyl chloride resins may generate toxic gases such as hydrogen chloride and highly toxic substances such as dioxins during combustion. It has been strongly requested.

る。The raw material of the thermoplastic acrylic resin film of the present invention is basically a blend of a rubber elastic body and an acrylic resin as described above, but generally, the tear strength and the flexibility are improved. For this reason, the amount of the rubber elastic body is relatively large as compared with the above-mentioned impact-resistant thermoplastic acrylic resin.

温度範囲が最も好ましい。[0008] The thermoplastic acrylic resin film of the present invention is bonded to a substrate sheet at a surface temperature of 80 to 160 ° C and integrated. If the integration temperature is lower than 80 ° C., sufficient adhesion cannot be obtained, and peeling and other undesirable phenomena occur during thermoforming such as curved surface processing of the composite sheet. In order to further improve the adhesiveness, it is preferable that the temperature is 90 ° C. or higher, which is higher than the softening temperature of the thermoplastic acrylic resin film. If the temperature exceeds 160 ° C., the thermoplastic acrylic resin film is greatly deformed, and it is difficult to obtain a good composite sheet. From the viewpoint of controlling film adhesion and film deformation, a temperature range of 90 to 120C is most preferable.

A decorative panel structure made of an impact-resistant thermoplastic acrylic resin having J / m 2 or more, preferably 2.5 KJ / m 2 or more, can be easily used even in an area where an impact may be applied carelessly. Defects such as cracks do not occur, which is practically preferable. The upper limit of the Charpy impact strength of the base sheet is not particularly limited as the upper limit increases, but is usually 10 KJ / m.
A value of about 2 is sufficient. As a method of integrating a thermoplastic acrylic resin film into a base sheet to form a composite sheet, a heat lamination method in which both are separately prepared, pressed under appropriate heating conditions and bonded, and a thermoplastic acrylic resin are used. When extruding a base sheet
An in-line laminating method of continuously laminating in the process can be cited, but the latter method does not require at least a substrate sheet washing step as compared with the above-described method of integrating by thermal laminating. Therefore, the method is simple and the process is excellent in mass productivity.

る。That is, a thermoplastic acrylic resin film having a decorative pattern printed thereon is continuously formed into a composite sheet by an inline lamination method under a tension of 1 to 10 kg / m (per unit length in the width direction of a roll). As a result, a composite sheet having excellent appearance quality can be stably obtained without irregularities or the like due to entrainment of air bubbles and dust in the air, and it is more industrially useful to use the composite sheet for a decorative panel structure. To explain in more detail, an extruder, a sheet die, a polishing roll, a usual sheet extrusion equipment including a take-up roll, a press roll is provided between the polishing roll and the take-up roll as necessary, At this time, the printed film is fed out, and is supplied to a polishing roll or a pressure roll under tension through a tension roll, and is pressed against an extruded base sheet.

である。At this time, the tension of the printing film is 1 to 10 kg / m (per unit length in the width direction of the roll) in order to continuously attach the printing film to the base sheet.
Under tension of the polishing roll or the pressure roll of the pressure bonding roll at a pressure of 0.1 to 8 ton / m (per unit length in the width direction of the roll). It is preferable because it can be uniformly laminated. When the tension is less than 1 kg / m, wrinkles are apt to be formed in the film. When the tension exceeds 10 kg / m, the residual stress of the printed film becomes large, which causes warpage of the composite sheet. With a roll pressure of less than 0.1 ton / m of a polishing roll or a pressure roll, air is easily entrained.
If it exceeds ton / m, optical distortion occurs, which is not preferable.
Further, by using an expander roll or a spiral roll as the tension roll, film wrinkling at the time of lamination can be favorably prevented, which is convenient.

部品数、工程数の削減ができるので、好ましい。The thickness of the base sheet is appropriately determined according to the intended use, but a thickness in the range of 1 to 5 mm is usually used. The thickness of the thermoplastic acrylic resin film is 0.1 mm in view of the ease of film formation and printing. Those having a range of 02 to 0.2 mm are suitable. Various materials can be used as a support for a decorative panel structure such as a vehicle interior, an interior interior, and the like. For the vehicle interior, ABS or PP glass fiber reinforced resin can be used. For the interior of the vehicle, synthetic resin, paper, ceramics, concrete,
Materials such as metal can be used. For example, when molding an automobile instrument panel, by adopting a gas injection method in which a molded product rib portion is hollow, it is possible to reduce the thickness of the material and to save reinforcing members such as metal rain, This is preferable because a great reduction in weight can be achieved and the number of parts and steps can be reduced.

In order to incorporate the composite sheet into a support having three-dimensional irregularities, it is necessary to previously form the composite sheet into a predetermined shape along the support by a sheet thermoforming method. Here, the sheet thermoforming method is a method of shaping a sheet in a state where the sheet is heated and softened. Specifically, the sheet is formed into a predetermined three-dimensional shape by any of vacuum forming, pressure forming, and hot pressing. Is the way. The composite sheet of the present invention, such as a box shape by the sheet thermoforming method,

An extruded sheet is formed by a conventional method using a unit including mφ, L / D = 32, a single axis), a sheet die, and three polishing rolls, a pressure roll, and a take-up roll, thereby forming a base sheet having a width of 900 mm. The gap between the sheet die discharge port and the polishing roll, and the rotation speed of the polishing roll and the take-up roll were adjusted, and the thickness of the sheet was adjusted to a target of 2 mm. The Charpy impact strength of the base sheet thus obtained was 1.4 KJ / m 2 .

(# 99141 transparent / product of Asahi Kasei Corporation) is used as a raw material to form a film having a thickness of 0.06 mm by an inflation method, and a roll-shaped material having a woodgrain pattern printed thereon is prepared. The paper is continuously supplied via a tension roll and a pressure roll so that the printing surface is located on the sheet surface side, and is attached to one surface of the sheet. At this time, the surface temperature of the base material sheet of the pressure-bonding roll was adjusted to 1 by adjusting the extrusion amount of the extruder.
Adjust to 05 ° C or 120 ° C. The tension roll stress in the attaching stage is 3 kg / m (per unit length in the width direction of the roll), and the pressure of the pressure roll is 0.6 ton.
n / m (per unit length in the width direction of the roll). The resulting composite sheet has substantially the same good appearance as an acrylic resin sheet obtained by a conventional method, substantially free of surface imperfections such as surface irregularities that impair the appearance.
