Surfaces of plastic parts such as automobiles, home appliances, and other industrial materials have been protected and decorated by various methods such as spray painting and hydraulic transfer. In addition to chemical and abrasion resistance features, plastic part surfaces often require high gloss, high image sharpness, weather resistance stable to ultraviolet rays, and various patterns. In particular, the surfaces of automotive interior and exterior plastic parts such as bumpers, side moldings, mirror housings, doors, etc., require a high level of surface protection and decorative properties.

Spray painting, such as undercoat, midway, and top coat, is a dangerous paint solvent evaporation that creates operator safety issues, severe air pollution, and environmental issues caused by emissions. In order to maintain the high quality level, a high cost occurs due to the multi-step paint work and the need for an environmental facility for preventing environmental pollution, and there are problems in that various patterns are difficult to implement.

1 is a method of transferring a printing pattern by floating a water-soluble polyvinyl alcohol film (1) printed with a decorative pattern on water (3), pressing the plastic molded article (2) onto the printing surface, and transferring the printing pattern. Due to the positional misalignment between (1) and the object (3), the defect rate of the decorative pattern is high, the decorative pattern is not precise, and the remaining polyvinyl alcohol film (1) has to be cumbersomely hard-coated to protect the surface after washing and transferring. There is a problem. In addition, there is a problem that discoloration occurs when used outdoors for a long time.

Such spray painting and hydraulic transfer products can cause unpleasant odor problems for drivers and passengers due to solvent evaporation problems when used as automotive interior materials, and require additional costs for recycling due to thermosetting resin coating. There is this.

In addition, after the transparent film such as polycarbonate resin, acrylic resin, and polyurethane resin printed with heat-resistant ink is molded into a three-dimensional shape, the product decorated in the injection mold has a problem of color discoloration due to ultraviolet rays when used outdoors for a long time. There is a problem that the print pattern is partially disappeared by the injection resin of the temperature.

In order to solve this problem, various approaches have recently been attempted to manufacture plastic sheet surfaces and decorative sheets using fluorine-based resins such as polyvinylidene fluoride (PVDF) and acrylic resins. For example, such sheets and methods of sheet production are disclosed in patent WO 88/07416; Patent US 5514427, Patent WO 99/37479, Patent JP 09-193189 A, Patent WO 94/03337, and Patent US 5108836. The sheet prepared by patent WO 88/07416 (corresponding patent of Korean Patent Publication No. 1995-2929) was applied by dissolving polyvinylidene fluoride resin and methyl methacrylate resin in a solution on a mobile polyester carrier and applying at high temperature. It was prepared by the method of drying. Sheets produced in this way require a polyester film to be discarded after sheet production. In addition, there is a manufacturing limitation to thickening the thickness of the transparent film layer required by the user. The production capacity is lowered because a slow line speed is required to apply and dry the resin-dissolved solution without bubble generation. In addition, it contains many organic solvents, so that a large amount of organic solvent gas is emitted during the drying process. Dissolving polyvinylidene fluoride resins requires strong solvents such as N-methyl pyrrolidone and these solvents are expensive. The weak point of the single-layer film using a high content of fluorine-based resin in such a synthetic resin laminated sheet is adhesion to other layers. For example, when printing or ink coating a fluorine resin monolayer film, there was a problem in that a corona treatment or a separate primer should be coated for surface activation.

U.S. Patent No. 5108836 (1992.4.28) discloses a surface protection film having a high layer of fluorine resin and a double layer structure of high acrylic resin. By using a two-layered surface protection film, a separate process from corona treatment or primer coating for surface activation can be avoided when printing or coating fluorine-based resin, but polyvinylidene fluoride resin and methyl methacrylate resin are dissolved in a solvent. It is manufactured by the solution casting method of coating and drying the solution, so a mobile polyester film which is discarded after the above-mentioned synthetic resin laminated sheet is needed, low production capacity due to slow line speed, large amount of organic solvent gas release, expensive strong solvent Problems such as use still remain.

In order to solve the above problems, in the present invention, a two-layer structure transparent film was manufactured using a coextrusion method that does not require a solvent and a transfer polyester film, rather than a solution casting method. Problems such as low production capacity due to slow line speed in solution casting method, release of large amount of organic solvent, use of expensive strong solvent, and use of moving polyester film were solved by film production using coextrusion method. The present invention is to develop a synthetic resin laminated sheet and a molded article useful for protecting and decorating plastic surfaces including a coextruded two-layer transparent film of different compositions consisting of a fluorine resin and an acrylic resin mixture. By manufacturing the coextruded two-layer transparent film, a synthetic resin laminated sheet excellent in weather resistance and interlayer adhesion can be obtained. There is also no use of transfer polyester carriers in the production of transparent protective films and in particular no solvent is required. Therefore, in manufacturing a molded article using a synthetic resin laminated sheet, it is possible to solve the problems of conventional spray painting and hydraulic transfer products and to impart excellent protective properties and decorative effects on the surface of plastic products.

2 illustrates one embodiment of the synthetic resin laminated sheet 18 of the present invention. In this embodiment, the synthetic resin laminated sheet includes the following layers. The present invention relates to a thermoformed and heat-sealable synthetic resin laminated sheet and a molded article which are continuously composed of the layers (10) to (16) below.

Coextrusion two-layer transparent film (12) consisting of 30 to 50% of fluorine resin and 50 to 70% of acrylic resin with a total weight of 100%

A first layer transparent film 10 composed of 50 to 95% of a fluorine resin and 5 to 50% of an acrylic resin with a total weight of 100%

A second layer transparent film 11 composed of 5 to 50% of a fluorine resin and 50 to 95% of an acrylic resin with a total weight of 100%

Printed layers of various patterns, optionally applied (13)                     

Color Ink Coating Layer (14)

Optionally Used Adhesive Layers (15)

Material Sheet (16)

[2 layer structure transparent film]

The two-layer structure transparent film 12 is composed of two layers of different compositions, and protects the printing layer 13 and the color ink coating layer 14 of various patterns selectively applied on the lower surface, and the synthetic resin laminated sheet ( It is a transparent, UV-stable durable film 12 that gives gloss and image sharpness to the surface of the molded product 40 using the 18).

The fluorine resin used in the present invention is a polyvinylidene fluoride homopolymer or a polyvinylidene fluoride copolymer copolymerized with a monomer copolymerizable therewith. The acrylic resin is a methylmethacrylate copolymer copolymerized with methylmethacrylate or a monomer copolymerizable therewith.

The first layer 10 of the transparent film located on the outer surface of the synthetic resin laminated sheet 18 is composed of 50 to 95% of a fluorine resin and 5 to 50% of an acrylic resin. Preferably it consists of 70-95% of fluororesins and 5-30% of acrylic resins. If the fluorine resin content is 95%, the adhesive strength with the second layer tends to be weak. On the other hand, when the content of the fluorine-based resin is 50% or less, UV stability and weather resistance tend to be weakened, and a blocking phenomenon occurs when the film is wound. The ultraviolet stabilizer content of the first layer 10 contains 0 to 1% with respect to 100% of the total content of the fluorine resin and the acrylic resin. If 1% or more of the UV stabilizer is contained, the UV stabilizer may bleed to the surface of the film, resulting in lowering of interfacial adhesion.

The second layer 11 of the transparent film is made of 5 to 50% of fluorine resin and 50 to 95% of acrylic resin. Preferably it consists of 10-30% of fluororesins and 70-90% of acrylic resins. When the acrylic resin content is 50% or less, dispersion of the UV stabilizer becomes difficult and the UV stabilizer tends to evaporate. The UV stabilizer content of the second layer transparent film may be contained in an amount of about 0.1 to 15% based on 100% of the total content of the fluorine resin and the acrylic resin, and preferably 0.5 to 5%. If the UV stabilizer content is 0.1% or less, the ultraviolet absorbing power is lowered and is inappropriate as a protective film.

The transparent films of the first layer 10 and the second layer 11 of the synthetic resin laminated sheet 18 may include other additives such as antioxidants, dispersants, coupling agents.

The two-layer structure transparent film 12 is characterized in that it does not require a separate corona treatment or primer treatment to improve adhesion before printing or color ink is coated on the second layer transparent film 11 surface.

The thickness of the two-layer structure transparent film 12 produced in the present invention is made of 10 to 150㎛, preferably 10 to 100㎛. The transparent film 12 having a thickness of 10 µm or less is degraded in weather resistance, and it becomes impossible to protect the printing layer 13 and the color ink coating layer 14 positioned below. In addition, the transparent film 12 of 150 µm or more does not show a marked improvement in weather resistance. The thickness of the 1st layer transparent film 10 consists of 2-50 micrometers, and at 2 micrometers or less thickness, weather resistance, pollution resistance, and chemical resistance fall. On the other hand, there was no significant improvement in the thickness over 50㎛. The second layer transparent film 11 containing a lot of UV stabilizers should be at least 20% of the total thickness in order to realize the surface protection function.

The transparent film 12 having a two-layer structure composed of a mixture of a fluorine resin and an acrylic resin is coextruded through an extrusion T-die or coextruded through blown blow molding in a molten state having a different composition.

Fluorine-based resins, acrylic resins, UV stabilizers and other additives are prepared in the form of petlets using a twin screw extruder prior to coextrusion.

[Print layer]

The printing layer 13 of various patterns is a layer which is selectively applied for giving various patterns to the appearance of the synthetic resin laminated sheet 18. The printing layer 13 advantageously contains flakes such as pigments, dyes and / or metal flakes, the composition of the printing layer 13 being detrimental to the second layer transparent film 11 which is the side on which the ink chemistry is printed. Includes solvents designed to print without impact.

Since the transparent film second layer 11 containing a high content of acrylic resin has excellent adhesiveness and printability, it can be used outdoors for a long time even when various ink binders such as PVC, urethane, acrylic resin, and fluorine resin are used in combination. Excellent adhesive performance can be achieved. Preferably it is advantageous to use an acrylic ink binder. The thickness of the print layer 13 is suitably 1 to 5 mu m, and gravure printing or rotary screen printing is suitable.

[Color ink coating layer]

The color ink coating layer should be sufficient to maintain the desired color of the molded article 40, and sufficient thickness, pigment and dye, on the order of 5 to 80 mu m, such that the color of the base sheet 16 located on the bottom surface is not visible. And / or additives such as metal flakes. The color ink coating layer 14 may be coated and dried by conventional coating techniques such as roll coating or slot die in the form of a solution when the resin laminated sheet 18 includes a printing layer 13 to which the resin sheet is selectively applied, and optionally applied. When not including the print layer 13 can be prepared by co-extrusion with the transparent film 12.

Since the transparent film second layer 11 containing a high content of acrylic resin is excellent in adhesiveness and printability, various ink binders such as PVC, urethane, acrylic resin, and fluorine resin can be used in combination. Preferably, it is advantageous to use an acrylic resin and a fluororesin mixed binder for a molded article 40 which requires high weather resistance, and an acrylic resin is used as a binder for a molded article 40 that does not require high weather resistance. Do. In the case of coating in the form of a solution, when the color ink coating layer 14 is thick, it is difficult to dry the solvent, and thus, an acrylic bead additive may be added to improve the drying speed.

[Adhesive layer]

The adhesive layer 15 is used for adhering the color ink coating layer 14 and the base sheet 16 and should have adhesion to both the color ink coating layer 14 and the base sheet 16. The adhesive layer 15 is selectively applied according to the resin type of the color ink coating layer 14 and the base sheet 16. Referring to the compatibility of each resin shown in Table 1, the use of the adhesive layer 15 is not necessary if the color ink coating layer 14 resin and the base sheet 16 resin can be heat-sealed. That is, if the color ink coating layer 14 contains an acrylic resin and the base sheet 16 is ABS, it is thermally fused, and thus, by the heat fusion of the color ink coating layer 14 and the base sheet 16 without using the adhesive layer 15. Adhesion is possible. If there is no heat fusion between the color ink coating layer 14 and the base sheet 16, it is possible to mix and use a resin capable of having heat fusion to both the layers 14 and 16. For example, when the color ink coating layer 14 made of acrylic resin and the thermoplastic polyolefin base sheet 16 are bonded, it is preferable that the adhesive layer 15 use an acrylic resin and a chlorinated polyolefin mixture.

[Base sheet]

Films 19, 20, 21, and (2) coated with a color ink coating layer 14 or an adhesive layer 15 on the two-layer structure transparent film 12 illustrated in FIGS. 22 is bonded to the base sheet 16 by heat and pressure. The method to be bonded is schematically illustrated in FIG. 4. The base sheet 16 is selected as a resin alone or as a mixture which may have thermal fusion with the resin used in the molded article 40 with reference to the resin-specific compatibility shown in Table 1. It is preferable to use the same resin as the resin used for the molded product 40. For example, if the resin of the molded article 40 is ABS, use of an ABS base sheet is preferable, and if the resin of the molded article 40 is PP, it is preferable to use a PP base sheet. The base sheet 16 is preferably a thermoplastic material that can be thermoformed into a three-dimensional shape, and should be easy to handle after being thermoformed and of a thickness that can be thermoformed. As illustrated schematically in FIG. 4, films 19, 20, 21, and 22 coated with a color ink coating layer 14 or an adhesive layer 15 on the substrate sheet 16 and the transparent film 12. ) Is laminated on the preheated heating drum 31 through a guide roll 30 and heated first before being heat fused on the heating drum 31 and then heat-bonded by the heat and pressure. It is bonded in and immediately cooled by the cooling roll 33 and then wound in the form of a roll 34.

[Vacuum forming]

If the molded article 40 is a three-dimensional shape, the synthetic resin laminated sheet 18 can be selectively vacuum formed into a three-dimensional shape. 5 schematically illustrates the vacuum forming. The resin laminated sheet 18 is heated enough to be vacuum formed by moving the clamp through a heating oven and then vacuum molded into a three-dimensional shape in the vacuum mold upper mold 50 and the lower mold 51. In the vacuum forming process, a vacuum pressure 52 is applied to the lower mold 51 by a vacuum pump. Cooling water may be circulated in the upper and lower molds 50 and 51 during the vacuum forming process so that the synthetic resin laminated sheet 53 formed in a three-dimensional shape is cooled to a solid state, and the upper and lower molds 50 and 51 are cooled. ) Should be closed for a time sufficient to allow the sheet 53 to cool sufficiently. The vacuum molded synthetic resin laminated sheet 53 is dried so as to match the shape of the injection mold 50 during the injection process and is ready for use in the injection process.

[Thermal Fusion of Synthetic Resin Sheets and Molded Products]

When the molding depth of the molded product 40 is not deep and the shape is not complicated, the synthetic resin laminated sheet 18 is molded in the injection mold of the injection process without the need for three-dimensional vacuum molding, and at the same time, the molded product (heated by the injection resin heat). Can be fused).

In addition, the synthetic resin laminated sheet 18 may be thermally fused with the base sheet 16 by the heat of the extruded resin on the surface of the molded article to be extruded without a separate molding process. Molded article 40 may have a variety of shapes, typically may have a rod, plate, profile shape.

Fig. 6 shows a cross section of the final molded article to which the synthetic resin laminated sheet 18 of the present invention is bonded by heat fusion.
