Next, the transfer material 1 is subjected to the SMC method or the BM method.
The design layer 3 is placed so as to be in contact with the FRP member 4 having the surface texture formed by the C method.

The FRP member 4 is mainly made of a thermosetting polyester resin, and is made of a fibrous material such as glass fiber or carbon fiber, or a glass fiber reinforced plastic containing an inorganic powdery filler such as talc or silica.

The surface grain is formed on the surface of the FRP member 4 by a SMC molding die grain, which improves the design effect, improves the scratch resistance of the surface, makes the scratch less noticeable, and improves the floor material. It is intended to have an effect such as anti-slip when used. Surface grain is usually 0.1-2 height

Further, in order to closely contact the surface texture of the FRP member 4 without any gap, it is preferable to use a transfer pad 5 having a flexible layer 6 capable of following the shape of the surface texture of the FRP member 4 ( 2-4). The soft layer 6 preferably has a hardness of 70 or less. The hardness of the flexible layer 6 is 7
If the value is 0 or less, the flexible layer 6 is easily deformed and easily follows the shape of the surface texture. In addition, the hardness referred to in the present invention refers to a value measured by a durometer A type spring hardness tester. As the flexible layer 6, silicone rubber, nitrile rubber butadiene rubber (NBR), styrene butadiene rubber (SBR), or the like may be used. In particular, silicone rubber is preferred because of its excellent heat resistance.

The shape of the flexible layer 6 is a flat plate shape (FIG. 2).
(See Figures 3 and 4)
It is good to In order to obtain an inverted shape of the surface embossed shape, it is preferable to use a method such as molding by casting silicone rubber or the like, or shaving.

In order to heat the transfer material 1 to a temperature higher than the heat diffusion temperature, the sublimation (diffusion) temperature of the heat transfer dye (generally 90 to 90)
200 ° C) or more. Further, in order to promote the sublimation of the heat transferable dye, it is preferable that the FRP member 4 is heated and kept warm.

To press from the base sheet 2 side, hydraulic pressure,
It is preferable to press the apparatus with a transfer pad which can be heated on a device such as a press machine which can apply a pressure by a pneumatic or mechanical pressure source.

The reason why the pattern is left for a certain period of time is because a pattern is formed by thermal diffusion sublimation, so that it takes time for the pattern to reach a certain density. Although the time for which it is left is a function of the temperature, it is preferably about 1 to 5 minutes.

Thereafter, the base sheet 2 is peeled off.

In this way, an indoor decorative material can be obtained.

In order to prevent re-diffusion of the heat transferable dye and to enhance the surface resistance from the surface texture side, it is adhered to an FRP member and overcoated with a material having a dye re-diffusion prevention function or a surface resistance enhancement function. You may.

Since the present invention has the above-described structure, it has the following effects.

The indoor decorative material of the present invention is configured such that a heat transferable dye penetrates into the inside of the surface of an FRP member having a surface texture formed by the SMC method or the BMC method to form a design. It is.

Therefore, since the heat transferable dye is impregnated into the inside of the FRP member, even if the surface of the FRP member is slightly worn, the design does not disappear.

Further, in the method for producing an indoor decorative material according to the present invention, a transfer material having a pattern layer containing a heat-migrating dye formed on a base sheet is formed by using a surface texture formed by an SMC method or a BMC method. The design layer is placed in contact with the FRP member having the pattern layer, and then a transfer pad heated to a temperature equal to or higher than the thermal diffusion temperature of the heat transferable dye is pressed from the base sheet side of the transfer material, so that the design layer The transferable dye is diffused and transferred into the FRP member from the surface texture side by the heat of the transfer pad heated by leaving the transfer pad heated for a predetermined time to form a pattern on the FRP member, and then the base sheet is peeled off. It is configured as follows.

Therefore, since the transfer is performed to the FRP member which is a molded product, the alignment between the design and the surface grain is easy, and no positional displacement occurs. Also, the molten FRP
The transfer material is brought into close contact with the FRP member by the transfer pad instead of the pressure, so that the transfer material can be prevented from being broken by adjusting the pressing speed and temperature.
Further, even if the transfer material does not completely follow the surface texture of the FRP member, the heat transferable dye in the design layer can be heated by the heat transfer dye.
Since the process shifts to the P member, the symbol can be reliably formed on the FRP member. As described above, a beautiful pattern can be easily formed on the FRP member having the surface texture formed by the SMC method or the BMC method.

In addition, if the FRP members on which the patterns are not formed are stored in advance, an indoor decorative material can be obtained by using a transfer material having an arbitrary design as needed, which is advantageous in production management. It is.
