制限が存する等の欠点がある。By the way, in the method for producing a resin molded body having an emboss that matches the pattern, the one using press molding in the +1+ term requires a step of mechanically attaching an emboss that matches the pattern to a decorative sheet having a pattern; This method is not only complicated, but also has the disadvantage that the embossing on the decorative sheet is easily crushed. Furthermore, the method in which the embossing step is carried out at the same time as the press forming described in item (2) has the disadvantage that the pattern on the decorative sheet and the embossing are difficult to synchronize, making it difficult to obtain a sheet of good quality. Furthermore, in the case of performing the post-emboss process in item (3), it is difficult to synchronize the pattern and the emboss, as in the case of item (2) above, and there is also the complexity of requiring a post-emboss process. . In addition, the method described in (4) in which room-temperature curable resin is poured requires a process of mechanically attaching an emboss that matches the pattern to a decorative sheet with a pattern, and a process of casting and curing the curable resin. However, there are disadvantages such as not only the process is complicated but also the resins that can be used are limited.

のである。On the other hand, the method of manufacturing a thermoplastic resin molded body having an emboss that matches the pattern of the present invention does not require a mechanical process for applying the emboss, so the process is simple, and the process is simple, and the pattern and the emboss do not match. The synchronization is perfect, the emboss effect is remarkable, and the height or low of the emboss can be adjusted as desired by selecting conditions.

成形における加熱に続く冷却を開始するのが良い。It goes without saying that plates, metal plates, etc. may be incorporated. ◇ The thickness of the thermoplastic resin layer involved in compression during press molding in the press molding material is 90~90 mm at the start of press molding.
When the press pressure is compressed to 40%, if the press pressure is maintained constant throughout the pressurization period, that is, the initial maximum press pressure is maintained, the press pressure is gradually reduced during the pressurization period. It has been found that this can be achieved in about 1/2 the pressing time compared to the press molding method. Furthermore, if the thickness of the thermoplastic resin layer at the start of cooling in press molding exceeds 90% of the initial thickness, the unevenness effect of embossing will be insufficient, and if it is less than 40%, the unevenness effect will not appear. This has the disadvantage that the pattern is disturbed. Therefore, in order to express a stable pattern with a remarkable emboss effect,
Preferably, when the compressed material is compressed to about 80 to 60%, cooling following heating in press molding is started.

ものである。In the resulting acrylic decorative board, which is a resin molded product, a printed pattern layer consisting of an abstract pattern formed through a transparent acrylic resin layer protrudes upward, and embossing that is in sync with the pattern layer is introduced. ◎ [Action of the Invention] The method for manufacturing a thermoplastic resin molded body having an embossment that matches the pattern of the actual invention is a method using printing ink. Press-molding a molding material in which the thermoplastic resin layer is a stack of a decorative sheet made of a thermoplastic resin sheet having a pattern layer and one or more thermoplastic resin layers in contact with the decorative sheet. A method for producing a thermoplastic resin molded article, which comprises melting a pattern layer and two or more thermoplastic synthetic resin layers that are in contact with the pattern layer in the thickness direction during press molding.
By fluidizing, distortion caused by the difference in flow behavior when the thermoplastic resin sheet and the pattern layer in the decorative sheet are melted at the same temperature is formed in the thermoplastic resin layer that is in contact with the pattern layer in the thickness direction. Alternatively, it is formed on the pattern layer and a thermoplastic resin layer that is in contact with the pattern layer in the thickness direction to obtain an embossing effect that synchronizes with the pattern.

塑性樹脂成形体が容易に得られるものである。In particular, in the method of the actual invention, during the press forming process of the molding material, the degree of deformation in which at least one of the upper and lower surfaces of the molding material extends in the horizontal direction is suppressed or prevented. Therefore, the distortion caused by the difference in flow behavior between the thermoplastic resin sheet and the pattern layer in the aforementioned decorative sheet when they are melted at the same temperature becomes more pronounced, resulting in a thermoplastic resin molded product with a clear embossing effect that synchronizes with the pattern. can be easily obtained.

生して固定されるためであると推定される。For example, in the youngest inventions 1 to 3, in which the melting temperature of the resin vehicle constituting the printed pattern layer in the decorative sheet is lower than the melting temperature of the thermoplastic resin sheet in the decorative sheet, the temperature of the molding material after the start of grease molding is When the temperature rises, the pattern layer portion first melts, and the flow resistance in the horizontal direction in the thickness direction of the molding material between the melted portion and the intervening film, embossing plate, frame, or press platen increases. A middle stage is reached in which the amount of water decreases, and as the press molding progresses, the whole becomes softer, and moreover, it is placed under pressure. As a result, the thermoplastic resin layer in the molding material begins to flow, but this flow is greater in areas near the intervening film, embossing plate, frame, or press surface plate than in areas farther away from the curvature. Because the velocity is high, a distribution of flow velocity occurs in the thickness direction. As described above, this flow is caused by the intervening film, embossing plate, or frame of the core layer, or the press surface plate in the pattern layer and the thermoplastic resin layer portion that is in contact with the pattern layer in the thickness direction. It is promoted because the resistance is small,
It is presumed that this is because the pressure in the part where the flow rate is high is higher, and in such a state, distortion occurs and becomes fixed. In addition, in the inventions of the youngest brothers 4 to 6, when the temperature of the molding material rises after the start of press molding, the pattern layer portion first melts, and the thermoplastic resin at least in the upper and lower portions in the thickness direction of the pattern layer melts. The sheet and the thermoplastic resin layer create an intermediate stage in which the flow resistance in the horizontal direction in the thickness direction of the living material is reduced, and further press forming progresses to soften the whole and, moreover, it can be placed under pressure. Become. For this reason, the thermoplastic resin layer in the molding material starts to flow in the horizontal direction, but this flow is caused by the intervening film, embossing plate, frame, or parts near the press platen to parts further away from them. Since the flow rate is slow compared to the above, a distribution occurs in the flow rate in the thickness direction. This flow is promoted in the pattern layer portion because the resistance to horizontal flow is reduced between the thermoplastic resin sheet and the thermoplastic resin layer that are in contact with at least the top and bottom of the pattern layer, and the flow rate is increased. It is presumed that this is because the pressure in the faster parts becomes greater, and in this state distortion occurs and becomes fixed.

When rises,
First, the non-printing pattern layer surface of the thermoplastic resin sheet in the decorative sheet is melted, and in the melted portion, the area between the intervening film, embossing plate, frame, or press surface plate is formed in the thickness direction of the molding material. A mid-shade stage is achieved in which the horizontal flow resistance is reduced, and the press molding progresses further, softening the entire product and placing it under pressure.

定される。Since the flow velocity is higher in areas near the embossing plate, frame, or press platen than in areas farther away, a distribution in flow velocity occurs in the thickness direction of the forming material. This flow is promoted in the non-printed pattern layer portion of the thermoplastic resin sheet because, as described above, the core layer has low resistance to the intervening film, embossing plate, frame, or press surface plate. As a result, the pressure in the parts where the flow velocity is high becomes greater,
It is presumed that this is because distortion occurs and is fixed in such a state.

The thermoplastic resin layer in the part realizes an intermediate stage in which the flow resistance in the horizontal direction with respect to the thickness direction of the molding material is reduced, and as the press molding progresses, the entire material softens and is placed under pressure. Become. For this reason, the thermoplastic resin layer in the molding material begins to flow in the horizontal direction, but this flow is caused by the intervening film and embossing plate.

れる。Alternatively, the flow velocity is slower in parts near the frame or the press surface plate than in parts farther away, resulting in a distribution in the flow velocity in the thickness direction. This flow is promoted in the non-printed pattern layer surface portion because the resistance to horizontal flow is reduced in the thermoplastic resin layer that is in contact with at least the top and bottom of the non-printed pattern layer surface in the thickness direction. It is presumed that this is because the pressure in the faster speed section becomes greater, and in this state distortion occurs and becomes fixed.

質的に利用し得る融点温度差である。In the inventions of youngest brothers 1 to 3, the difference between the melting point of the thermoplastic resin (vehicle) in the printed pattern layer of the decorative sheet and the melting point of the thermoplastic resin sheet in the decorative sheet is 5.
It has been confirmed that a sufficiently effective embossing appears when the temperature is above It has been confirmed that when the difference between the melting point of the thermoplastic resin layer and the melting point of the thermoplastic resin layer directly in contact with the printed pattern layer is 5° C. or more, a sufficiently effective embossing is produced. In addition, there is no particular limit on the upper limit of the difference between the melting point of the vehicle of the printed pattern layer and the melting point of the thermoplastic resin layer that is in direct contact with the printed pattern layer, but there may be problems with handling workability, raw materials, etc. The practically usable melting point temperature difference is from about 40°C to about 40°C.

In the inventions of the youngest brothers 4 to 6, an even higher embossing effect can be obtained when the thermoplastic resin layers constituting both the upper and lower pattern layers of the decorative sheet have different thermal melting behavior. It will be done.

If the thermoplastic resins in the thermoplastic resin layers above and below the pattern layer are the same, the emboss effect is difficult to appear, so the printed pattern layer is placed above the thermoplastic resin layer in the thickness direction, that is, the resulting press It is preferable that the press molded body is exposed above the center of the thermoplastic resin layer in the molded body.

効果を奏するものである。[Effects of the Invention] The method for manufacturing a thermoplastic resin molded body having an emboss that matches the pattern of each of the present inventions does not require mechanical or chemical steps for applying the emboss, so the manufacturing process is simple. Moreover, embossing is introduced due to the difference in behavior due to thermal melting between the thermoplastic resin layer and the pattern layer during press molding, and on the thermoplastic resin layer to be molded,
At least one side of the lower side is suppressed or prevented from deforming in the horizontal direction during press molding, which is caused by the difference in flow behavior due to thermal melting between the thermoplastic resin layer and the pattern layer. Since the distortion becomes noticeable, the synchronization between the pattern and the emboss is perfect, the unevenness of the emboss is noticeable, and the height of the emboss obtained by the selection of the thermoplastic resin layer in the press molding material and the selection of the press molding conditions. This has the advantage that the height can be adjusted arbitrarily.
