- the present inventor has studied conditions for preventing the simultaneous-painting sheet from breaking at the time of molding with respect to the first problem of the related art described above. As a result, it was found that the above characteristics (1) to (3) were required.
- the reason why the simultaneous painting sheet 3 breaks during injection molding is that the heat of the molding resin 10 is applied to the molding simultaneous painting sheet 3 and the molding simultaneous painting sheet 3 is stretched along the flow of the molding resin 10. Sometimes, this is because the molding simultaneous painting sheet 3 has no strength against this.
- the injection temperature of most molding resins 10 is 150-280 ° C. Therefore, first, (1) 150.
- simultaneous painting is performed with various simultaneous painting sheets, and the simultaneous painting sheet that broke during molding and the simultaneous painting that did not break Sheet 3 was separated.
- (II) 2 8 0 for the case of injection molding the moldable polycarbonate resin at that temperature in ° C, subjected to similar-mold sheet decorating, shaping simultaneously did not break and the molded foil-decorating sheet was broken during molding Painting sheet 3 and were separated.
- the temperature of the simultaneous painting sheet surface during molding was measured, the heat of the injection-molded resin was transmitted, and in the case of (I) above, it was around 62 ° C, and in the case of above (II), it was 94%. ° C.
- the temperature range was 6 2 to 9 4 ° C, the injection molding as described above
- Most of the molding resin used for molding has an optimum injection temperature of 150 to 280 ° C, and the heat of the resin is transmitted to the sheet for simultaneous painting to raise the temperature of the surface of the sheet for simultaneous painting to 28 ° C. This is because the sheet with simultaneous painting must have strength that does not break even when the temperature is raised to 0 ° C.
- Some molding resins have an optimum injection temperature exceeding 280 ° C. However, if such a resin is used, no matter how much the material of the sheet with simultaneous painting is improved, deterioration will occur.
- Some molding resins have an optimum injection temperature of less than 150 ° C, but if such resins are used, the performance of the simultaneously molded article obtained will be insufficient in heat resistance.
- test piece 13 of a molded simultaneous painting sheet having a width of 1 O mm was placed on a pair of chucks based on the measurement method of
- the environmental temperature is a temperature in a state where the test piece is heated to the same temperature as the atmosphere around the test piece.
- Specimen 13 was obtained by cutting a simultaneously painted sheet with a width of 1 O mm and a pair of chucks 15 and 16 into a size that could be used for a tensile test at a check inter-quence distance of 5 mm.
- the reason why the size of the test piece 13 is not increased is to prevent the test piece 13 from softening and becoming wrinkled under the above-mentioned environmental temperature before the test piece 13 is pulled. Also, if the size of the test piece 13 is too small, the measurement error increases. Therefore, measurement errors can be minimized. As a result, the size became as above.
- the upper check 15 is fixed with the screw 14 while sandwiching the upper end of the test piece 13.
- the lower chuck 16 is fixed by screws 14 with the lower end of the test piece 13 interposed therebetween. As shown in FIGS. 12 to 14, the upper chuck 15 is fixed to the testing machine, while the lower chuck 16 is moved downward by the movable member 17 at a speed of 50 O mtnZ. The test piece 13 descends to apply a tensile force.
- test piece 13 was pulled at a speed of 50 OmmZ because the drawing speed of the simultaneous painting sheet was too fast during the actual three-dimensional processing and injection molding, and it was possible to reproduce and measure it. Due to the small number of devices, the speed that seems to be the fastest in the range that can be measured with a general tensile tester was selected. Even though this is still slower than the speed at which the simultaneously painted sheet is stretched during processing, the measured data hardly changes even if the tensile speed setting is changed, so this is enough to simulate.
- the simultaneous molding painting sheet 3 is used for the mold 4 for injection molding.
- a step of inserting the sheet into the sheet 5 is required, and the strength of the stiffness (Rigidity) is required for the simultaneous painting sheet 3.
- the strength of the waist is proportional to the cube of the Young's modulus and the thickness of the simultaneous painting sheet 3 at 25 ° C.
- the Young's modulus of the simultaneous simultaneous painting sheet 3 of the first embodiment of the present invention is determined by the above-described tensile test at the above width of the test piece 13, the distance between the chucks 15 and 16, and the above speed. Initial tensile modulus at the time of the measurement (that is, at a temperature of 25 ° C, as shown in Figs.
- the temperature at which the property of the simultaneously painted sheet changed when heated was 40 to 2 ° C.
- the width of 10 mm A test piece 50 of the simultaneous painting sheet was fixed at a chuck inter-distance of 5 mm using a pair of chucks 52 and 53, and one end of the test piece 50 was applied with a load of 20 gf at a constant speed of 50 OmmZ.
- the tensile elongation at break when the tensile test was performed was required to be 130% or more.
- the upper chucking 52 is fixed by screws 51 in a state sandwiching the upper end of the test piece 50.
- the lower chuck 53 is fixed by screws 51 with the lower end of the test piece 50 sandwiched therebetween.
- Chuck 53 of lower descends downward to 50 Omm / min by the movable member 54 Test A tensile force is applied to the piece 50.

It is necessary to extend without breaking. Therefore, the range of the temperature at which the properties change with heat was set at 40 to 200 ° C.
- the more optimal range of the temperature at which the property changes due to this heat depends on the intended use. For example, for home appliances such as refrigerators and air conditioners, the size of the product is large and the stereo formability is important, so it is better to select a material whose properties change with heat at a temperature of 40 to 160 ° C. On the other hand, for automotive interior parts, considerable heat resistance and deep three-dimensional workability are required, so it is better to select a material whose properties change with heat at a temperature of 60 to 150 ° C.
- the preferable range of the total thickness of the simultaneous forming painting sheets 3, 45 is 50 to 200.
- it is 250-700 ⁇ m. The reason is that if it exceeds 700 ⁇ m, it is difficult to roll the simultaneous-painting sheet simultaneously, and it will not be possible to continuously send and process the simultaneous-painting sheet. .
- an adhesive layer may be formed in advance on the surface of the backing sheet that is to be integrally bonded to the molding resin. Even if the adhesive layer is not present, the backing sheet layer basically functions as an adhesive layer. However, the presence of the adhesive layer makes it possible to further firmly adhere to the molded resin.

- the second embodiment is directed to a second problem, namely, to prevent scratches.
- the outermost surface of the molded simultaneous painting sheet that is, the surface of the base sheet is easily damaged when the molded simultaneous painted product is obtained.
- the base sheet of the simultaneous painting sheet is made of a material such as polybutadiene resin, a simultaneously painted article can be obtained in manufacturing, but if this is subsequently assembled and processed as a part, the nail marks of the assembler will be removed.
- the power to make the sheet surface defective is S Service.
- the present inventor has examined how much surface hardness is necessary for the second problem so that the nail mark of the assembler does not increase the ratio of defective products on the surface of the base sheet. .
- the simultaneous-painting sheet having a pencil hardness value of 3 B to 2 H measured from the surface of the above-described simultaneous-painting sheet opposite to the surface to be adhered to the molding resin. I knew it was fine. In other words, a base sheet having a surface hardness of less than 3 B in pencil hardness, specifically, a simultaneous painting sheet made of a polybutadiene film could not be used.
- the method of measuring the surface hardness is 15 O mm X using a lead brush tester for paint film (see Fig. 15, Fig. 50, Fig. 51) based on JISK5401--1969.
- This is a method in which the surface of a test piece 27 cut to 7 O mm is drawn using a pencil and the hardness of the surface is determined based on the presence or absence of scratches. It is the pencil hardness when less than.
- the drawing is performed by pressing the pencil 18 at 45 ⁇ 1 degrees against the test piece 27 with the weight 20 and moving the test piece mount 19 in that state.
- reference numeral 19a denotes a stopper for fixedly attaching the test piece 27 to the test piece mounting base 19
- reference numeral 19b denotes a test piece stopper rod.
- a non-stretched or low-stretched polyethylene terephthalate film, an amorphous or low-crystalline polyester copolymer film, an acrylic film, polycarbonate Tofilm, polypropylene film, polybutylene terephthalate film, polystyrene film, polyurethane film, acrylonitrile butadiene styrene copolymer film, nylon film, polyvinyl chloride film, fluorine film, or cellulose acetate film may be selected.
- acrylic film is outstandingly excellent in transparency and weather resistance, and was a high value-added film as a base sheet in terms of improving the sharpness of design and protecting the pattern layer. .
- the degree of crystallinity should be adjusted so that the hardness becomes 3 B or more.
- the third embodiment has a third problem, that is, a problem of preventing a trimming cross section line from being seen.
- a third problem is that the cut end surface of the simultaneous-painting sheet integrated with the molding resin by trimming is not buried in the molding resin and is exposed, resulting in poor design.
- the boundary line between the simultaneous painting sheet and the solid molding resin surface was conspicuous, and the simultaneous simultaneous painting was performed. There was a problem that the design was poor.
- the molded simultaneous painting sheet according to the third embodiment of the present invention has a thickness of 200 / m, excluding the thickness of each backing sheet.
- the color of the backing sheet is a dark color within the following range in the CIE1976 L * a * b * color system, and the simultaneous painting sheet is constituted.
- the above-mentioned simultaneous molding and painting system except for the thickness of each of the backing sheets 66 is performed.
- the thickness of the sheet 61 is 200 / m or less, and the color of the backing sheet 66 is darkened so as to be within the following range in the CIE1976 L * a * b * color system.
- the reason for limiting the color of the backing sheet layer 66 in this way is as follows. That is, when performing the trimming process using a die press having a sharp blade 70, the simultaneous molding painting sheet 61 is not completely cut vertically, but its cut end face 67 Has an angle with respect to the front and back of the painted film 61 (see Fig. 32). Even when trimming by laser cutting, if the simultaneous painting sheet 61 is three-dimensionally added to the drawing shape by preforming before trimming, the direction of irradiation of the laser beam 71 Therefore, the cut end surface 67 has an angle with respect to the front and back surfaces of the simultaneous painting sheet 61 (see FIG. 33).
- the molding resin 69 used for automotive interior parts is often black or a similar color. As a result, most of the light is absorbed on the surface where the molding resin 69 is exposed, and there is little reflection.
- the end face 67 is formed coarsely by cutting, and light is scattered, so that the see-through rate when viewed from behind the cut end face 67 is poor.
- the cut end face 6 7 of the picture layer 6 3 and the picture layer The cut end face 67 of the second pattern layer 68, which is similar in color to the base of 63, is also a lighter color than the molding resin. As a result, compared to the surface where the molding resin is exposed, only the light (or color) reflected on the entire cut end surface of the simultaneous painting sheet 61 is conspicuous.
- the portion of the backing sheet layer 66 of the molded simultaneous painting sheet 61 is black or black so that the reflected light (or color) of the entire cut end face 6.7 of the molded simultaneous painting sheet 61 is not conspicuous. A color similar to that, and the backing sheet 6 Layers other than 6
- the thickness of the transparent resin film 62, which functions as a film, and the pattern layer 63, which has the wood grain conduit layer 64, and the base layer 65, and the second pattern layer 68, is 20.
- the simultaneous forming painting sheet 61 is fixed to a preforming mold having a concave portion for deep drawing by means of a clamp or the like.
- the simultaneous forming painting sheet 1 is heated and softened by a heat source and the preforming mold is heated. Vacuum suction from the side to make close contact with the surface of the preform.
- the vacuum suction is released, and the simultaneous molding painting sheet 61 is removed from the preforming mold.
- an unnecessary portion of the simultaneous painting sheet is trimmed to obtain a desired three-dimensionally shaped simultaneous painting sheet 61.
- the three-dimensionally formed simultaneous painting sheet 61 is inserted into a cavity mold having a concave portion for deep drawing, and is fixed to the cavity mold.
- the cavity mold and the core mold of the injection molding mold 72 are clamped to form a closed space between the molding simultaneous painting sheet 61 and the core mold. During this time, the molten molding resin 69 is injected (see Fig. 30 and Fig. 31). After cooling, the cavity mold and core mold are opened, and the molding simultaneous painting sheet 6 is obtained.
- This molded insert-formed product is obtained by trimming the simultaneous-painting sheet 61, ie, the reinforcing sheet, ie, the backing sheet 66, whose end face is black and the total thickness of the other laminates Is not more than 200 // m, so that even if the line of the cut end face 67 of the simultaneous painting sheet 61 is exposed, it is not conspicuous, which is preferable in design.
- the material of the backing sheet 66 has the above-mentioned characteristics (1) to (3) when it is formed into the simultaneous painting sheet 61,
- the pencil hardness value measured from the surface opposite to the surface to be bonded to the molding resin of the heating sheet 61 is 3B to 2H
- the base sheet 62 is an unstretched or low-stretched polyethylene terephthalate film, Non-crystalline or low-crystalline polyester copolymer film, acrylic film, polycarbonate film, polypropylene film, polybutylene terephthalate film, polystyrene film, polyurethane film, atarilonitrile butadiene styrene copolymer film, nylon film, polyvinyl chloride film, It must be made of a material that satisfies the conditions such as fluorine film or cell opening-acetate film.
- Such materials for the backing sheet 66 include unstretched or low-stretched polyethylene terephthalate film, non-crystalline or low-crystalline polyester copolymer film, polypropylene finolem, polyethylene film, polystyrene finolem, fluorine film, A polybutylene terephthalate film, a methacrylstyrene copolymer film, an acrylonitrile butadiene styrene copolymer film, a polycarbonate film, a polyurethane film, a nylon film, a polyvinyl chloride film, a nitrocellulose film, and the like.
- the base sheet 62 is made of a material which is easily vaporized and foamed, a problem arises in that the surface of the simultaneous painting sheet 61 becomes somatized even if the backing sheet 6 is made of the above-mentioned material. This problem and its solution will be described below.
- the fourth embodiment has an object to prevent a fourth problem, that is, an orange peel (yuzu skin) state.
- the fourth problem is that when forming into a desired shape by vacuum forming, the moisture contained in the sheet material evaporates and foams due to the heat during vacuum forming, and the surface of the simultaneous painting sheet becomes orange-peeled. In some cases, it was easy to see and the design was impaired, resulting in defective products. In such a case, a material with a low content (a material that prevents vaporization and foaming) is selected because the vaporized foaming component contained in the backing sheet material often causes the generation of yuzu skin. It is preferable to do so.
- the molded simultaneous painting sheet according to the fourth embodiment of the present invention is configured such that the material of each of the backing sheets is a material that prevents vaporization and foaming.
- the material of the backing sheet 104 is configured to be a material that prevents vaporization and foaming.
- 101 is a base sheet
- 102 is a picture layer
- 103 is an ABS film for strengthening the adhesiveness with the molding resin.
- the backing sheet 10 since the vaporized foaming component is often water, the backing sheet 10
- Examples of such materials include unstretched or low-stretched polyethylene terephthalate film, non-crystalline or low-crystalline polyester copolymer film, water absorption of 0.15% or less, polypropylene film of 0.03% or less, and water absorption of 0%.
- the fifth embodiment has a fifth problem, namely, prevention of warpage.
- the fifth problem is that when the shrinkage rate differs greatly between the material of the base sheet and the backing sheet (for example, the base sheet is made of an acrylic film (shrinkage rate of 5 to 100 0), and if the backing sheet is a normal polypropylene film (shrinkage ratio: about 15 1 000), this will cause warpage in the simultaneous painting sheet after three-dimensional processing, resulting in trimming. In addition, there is a problem that it is difficult to paint simultaneously with molding.
- the molded simultaneous painting sheet according to the fifth embodiment of the present invention includes a force in which a difference in shrinkage between the base sheet and the backing sheet is OZl 000 to 8/1000, or
- the sheet was composed of a plurality of sheet laminates, and the difference in shrinkage between the base sheet and the backing sheet furthest from the base sheet was 100 to 8/1000.
- the base sheet is made of an acrylic film.
- the backing sheet is a polypropylene film 83 simultaneously molded with the polypropylene film 83. It is preferable to modify a polypropylene film having a large molding shrinkage.
- 82 is a picture layer.
- a polypropylene film 83 contains a olefin-based rubber 84 and a filler 85 to suppress molding shrinkage.
- the mechanism is rubber
- EPM ethylene propylene rubber
- EPDM ethylene-propylene-gen terpolymer
- TPE thermoplastic elastomer
- EVA ethylene acetate butyl
- filler In addition to talc and calcium carbonate, titanium oxide, aluminum hydroxide, ferrite, carbon fiber, glass fiber ii, silica, myriki, carbon black, clay, anoremina, Wood flour or felt.
- the effect of suppressing the gradual shrinkage of the polypropylene film when cooling the heated sheet increases as the content of the olefin rubber and the filler increases, but the effect of the olefin rubber decreases.
- the propylene film becomes softer and the rigidity of the simultaneous painting sheet decreases.
- the filler separates and shrinks from the polypropylene film surface during the vacuum forming process, and the polypropylene film surface becomes uneven, which also affects the acryl film. Decreases the design of the simultaneous painting sheet.
- the content of the olefin rubber is in the range of 20 to 150 parts by weight based on 100 parts of the polypropylene resin.
- talc was used as the filler
- the content of the filler was found to be 5 to 20 parts by weight in terms of 100 to 100 parts of the polypropylene resin within an appropriate range.
- the best suitability range of the above both was 50 to 100 parts of EPM or EPDM and 10 to 15 parts of talc with respect to 100 parts of polypropylene resin in terms of weight.
- a problem occurs due to excessive addition of the olefin rubber or the filler, as shown in FIG.
- the reason for this is that the content of the olefin rubber contained in the polypropylene film layer closer to the acryl film becomes smaller, so that the decorative film as a whole Since the rigidity is maintained and the filler content is low, the filler is less likely to separate from the polypropylene film surface due to heating during preforming, and even if separated, the polypropylene closer to the acryl film This is because it is blocked by the film layer and does not reach the acrylic film. .
- the polypropylene film layer closer to the acryl film it is preferable to increase the thickness of the polypropylene film layer closer to the acryl film and to reduce the thickness of the polypropylene film layer farther from the acrylic film (the outermost polypropylene film layer).
- the polypropylene film layer closer to the acrylic film also includes the polypropylene film layer that is in direct contact with the acrylic film. The reason is that, generally, the larger the film thickness, the smaller the shrinkage tends to be. Therefore, by increasing the thickness of the polypropylene film layer closer to the acrylic film, the effect of the shrinkage of the polypropylene film layer farther from the acrylic film can be suppressed from reaching the acrylic film.
- the thickness of the polypropylene film layer remote from the acryl film is preferably equal to or twice the thickness of the acrylic film.
- the shrinkage is not as small as that of an acrylic film. Therefore, if the film thickness is not made larger than that of the acrylic film, the entire simultaneous painting sheet will be warped toward the polypropylene film layer side.
- the thickness of the propylene film layer is more than twice the thickness of the acrylic film, the shrinkage ratio does not change.
- the content of the filler contained in the polypropylene film layer farther from the acryl film (the outermost polypropylene film layer) is 100 to 30 parts by weight in terms of 100 parts of the polypropylene resin. Is an appropriate amount. The reason is that when the filler is contained in an amount of 30 parts or more, not only is it difficult to form a three-dimensional shape during preforming, but also it is difficult to adhere to the molding resin (or adhesive layer). On the other hand, if it is less than 10 parts, the effect of suppressing shrinkage becomes insufficient, and This is because it warps to the propylene film layer side. (Sixth embodiment)
- the sixth embodiment is directed to a sixth problem, namely, to improve the registration accuracy of a picture.
- the sixth problem is that the simultaneous painting sheet that can be three-dimensionally processed is easily deformed by the tension of the printing press and the drying heat applied when forming the pattern layer, so that the registration accuracy of the wood grain pattern etc. This is a problem that can only be applied to loose picture patterns. If these sheet layers are made of a material having a very high heat resistance, there is a problem that the sheet cannot be stretched and cannot be processed into a three-dimensional shape. Therefore, a material having a relatively low heat resistance cannot be selected. However, when a material with low heat resistance is selected, there is a problem that misregistration occurs during the printing and drying process, and the printing becomes difficult.

Thereafter, the backing sheet 33 is laminated.
- the backing sheet 33 is laminated on the pattern layer 32 side of the base sheet 31. Thereafter, the carrier sheet 34 is peeled off.
- another carrier sheet 34 is used as a printing material, and a pattern layer 32 is once formed on the surface thereof, and then a base sheet 31 is laminated on the pattern layer 32 side.
- the picture layer 32 is transferred to the base sheet 31 by peeling and removing the carrier sheet 34 as shown in FIG.

- the carrier sheet 34 has a dimensional change rate of 0.6% at an environment temperature of 90 ° C. A material having high tensile strength and excellent surface smoothness is used.
- Carrier sheet 34 with a dimensional change rate of 0.6% or less at an environmental temperature of 90 ° C is an inexpensive biaxially stretched polyester film because it is peeled off in the process of manufacturing a simultaneously painted sheet. It is preferable to use a biaxially stretched polypropylene film.
- the environmental temperature was set to 90 ° C because the ambient temperature in the drying unit installed in a normal multicolor printing machine is 60 to 90 ° C, and the highest value, 90 ° C Is adopted. Drying at as high a drying temperature as possible allows the residual organic solvent contained in the ink of the picture layer 32 to be scattered and prevents the simultaneous painting sheet 45 from being deteriorated due to the residual organic solvent.
- the dimensional change rate as used herein means that a sheet (8 Omm as an example of the sixth embodiment of the present invention) having a certain dimension at normal temperature (20 ° C.)
- 0.5Z80 (0.6%) as an example of the sixth embodiment.
- the reason why the dimensional change rate was set to within 0.6% is that the dimensions of the formed simultaneous painting sheet were 80 mm x 250 mm for the air conditioner heater panel in order to actually obtain a molded simultaneous painting sheet.
- the printing register accuracy must be within ⁇ 0.5 mm, which does not cause any discomfort to the printing register deviation, at least when viewed by the naked eye, and is set to 0.580 or 0.6%.
- the thickness of the carrier sheet 34 is preferably in the range of 5 to 300 ⁇ m. If it is less than 5 ⁇ m, the carrier sheet 34 may be easily cut due to the tension of the printing press, and if it exceeds 300 / m, it will be difficult to install it on a rotary printing press and productivity will decrease.
- the carrier sheet 34 having a thickness of 15 to 50 ⁇ m has good workability for bonding and peeling to the base sheet 31 and is more preferable. like this By using a thinner carrier sheet 34, it is possible to produce prints with a multi-color rotary press, compared to printing a pattern layer 32 directly on a substrate sheet 31 of several hundreds / m. Therefore, mass productivity is improved.
- the carrier sheet 34 is separated from the carrier sheet 34 so that the carrier sheet 34 can be easily separated from the base sheet 31 or the picture layer 32 can be easily transferred from the carrier sheet 34 to the base sheet 31 or the backing sheet. It is also good to apply a mold treatment to peel and chew.
- the carrier layer 3 4 is peeled off from the base sheet before the pattern layer 3 2 is formed, or the pattern layer 3 2 is placed on the carrier sheet 3 4 until the pattern layer 3 2 is transferred. 5

- the movable mold 35 is closed with respect to the fixed mold 36, and the molten molding resin 40 is injected into the cavity 43 from the gut portion 39 of the fixed mold 36, and the molding resin 40 is discharged. It is solidified to form the resin molded product 41 in the cavity 43, and at the same time, the molding simultaneous painting sheet 45 is integrally bonded to its surface (see Fig. 23). Then, after removing the resin molded product 41 from the movable mold 35, unnecessary portions of the simultaneous painting sheet 45 adhered to the resin molded product 41 are removed (see FIG. 24). In the case where the trimming process has been performed to a desired shape in advance as described above, it is not necessary to remove an unnecessary portion of the simultaneous forming painting sheet 45.
- the movable mold 35 and the fixed mold 36 as molds for injection molding are not particularly limited to the above-described embodiment, but have a gate section 39 for injecting the molding resin 40.
- the fixed mold 36 and the movable mold 35 are closed, the fixed mold 36 and the movable mold 35 are closed. What is necessary is to use a material in which a plurality of cavities 43 are formed.
- the molding simultaneous painting sheet 45 set in the cavity 43 formed by the movable mold 35 for injection molding and the fixed mold 36 covers the cavity forming surface 37.
- the cavity 43 may be one that forms a hole in the resin molded product 41.
- the recess forming the cavity 43 may be formed in either the fixed die 36 or the movable die 35.
- the movable mold 35 or the fixed mold 36 may have a clamp member 38 for pressing and fixing the molded simultaneous painting sheet 45 around the concave portion (see FIGS. 21 to 23).
- the clamp member 38 may be installed on the fixed mold 36 or the movable mold 35.
- the molding resin 40 is not particularly limited. Typical molding resins 40 used for interior and exterior parts of automobiles include polycarbonate resin, atalylonitrile butadiene resin, polypropylene resin containing talc, and alloys thereof.
- the mold of the injection molding machine can be applied not only to the case of a two-piece mold but also to the case of a three-piece mold.
- the seventh embodiment has a seventh problem, namely, a problem of insufficient concealment of the picture layer.
- the seventh problem is that when the pattern layer must be formed with a low hiding power and a color cast that is significantly different from the color of the backing sheet (for example, highly saturated yellow), the effect of the color of the backing sheet can be reduced. That is, the desired color appearance may not be obtained.
- the simultaneous simultaneous painting sheet according to the seventh embodiment of the present invention has the following problem in relation to the backing sheet 66 and the picture layer 63.
- the structure was such that the picture layer 68 was formed.
- the picture layer 63 is formed by a general-purpose printing means or the like, there are cases in which the color material of each color has a high concealing color and a color concealment which is not so depending on the difference in the concealing power of the coloring material of each color. If the pattern layer 63 needs to be formed with a color appearance that is low in concealment and significantly different from the color of the backing sheet 66 (for example, highly saturated yellow), the effect of the color of the backing sheet 66 In some cases, the desired color may not be obtained.
- the second pattern layer 68 is formed in order to improve the hiding power of the pattern layer 63.
- the second pattern layer 68 may be formed by coating or a sheet.
- the material of the second picture layer 68 is preferably a material that prevents vaporization and foaming, similarly to the backing sheet 66.
- the foaming component in the backing sheet 66 is vaporized and foamed by interposing the second pattern layer 68 that prevents vaporization and foaming. This is because the surface of the simultaneous painting sheet 61 can be suppressed from appearing to be yuzu-skin-like. This is presumably because only the backing sheet is vaporized and foamed, and the second pattern layer 68 prevents the gas generated from reaching the pattern layer 63.
- the material of the second pattern layer 68 include, for example, polyethylene. Resin, polypropylene resin, styrene resin, flame-retardant ABS resin, or thermoplastic polybutadiene resin.For details, polypropylene resin with a water absorption of 0.03% or less, water absorption of 0.
- the thickness of the second picture layer 68 is preferably 10 / m or more in order to obtain the concealing property and the vaporization foaming prevention property, and is preferably less than 200 / im in order to prevent the trimming sectional line from being visible.
- the above molding resin is not particularly limited, but the most typical molding resins used for interior and exterior parts of automobiles and electric appliances are polystyrene, acrylonitrile styrene copolymer resin, acrylonitrile butadiene styrene copolymer resin. Or polycarbonate resin and polypropylene resin.
- the painting sheet is preferably made mainly of acrylic resin, styrene resin (including styrene elastomer resin), acrylonitrile butadiene styrene resin, thermoplastic polybutadiene resin, or polycarbonate resin.
- the simultaneous painting sheet is preferably made of a polypropylene resin or a polyethylene resin in consideration of the ease of recycling after use and the adhesion to the molding resin.
- the most common of the three-dimensional processing methods is the vacuum forming method, which is a simultaneous painting method.
- a sheet is heated to above its softening point to make it soft and extensible, and the sheet is suctioned under vacuum to form the inner surface of the mold cavity for vacuum forming.
- This is a method of forming a desired three-dimensional shape by pulling and adhering to the object.
- there are a pressure forming method, a press forming method for pressing heated rubber, a press forming method, and the like.
- trimming method there are a method of burning off the simultaneously-painted sheet by irradiating a laser beam, and a method of preparing a trimming punch and punching out the simultaneously-painted sheet by press working.
- the trimming-removed three-dimensional shaped simultaneous painting sheet is set in a mold for injection molding so as to be fitted into the mold, the mold is closed, and the molten molding resin is injected into the cavity to form the molding resin. Is solidified to form a resin molded product, and at the same time, a molding simultaneous painting sheet is integrally adhered to the surface thereof.
- the base sheet or the backing sheet may be colored without providing a picture layer, so that the simultaneous painting sheet is colored.
