Description

505563 Α7 Β7 V. Description of the invention (丨) [Technical field to which the invention belongs] ^ The present invention relates to a metal sheet covered with -μ poly Θ cypress tree 1, which has high hardness and excellent embossability and decorative design. , Insulation, chemical resistance and others, it is applied to office appliances such as electrical / electronic devices, audio devices, office appliances such as photocopiers / printers and others. [Related arts] So far, the metal sheet system of soft plasticized polyvinyl chloride and polyolefin mainly composed of polyethylene, polypropylene, thermoplastic acrylic resin, fluororesin, or biaxially stretched polyester film, etc. Used as the housing or internal parts of office appliances such as electrical / electronic devices, audio devices, office appliances such as photocopiers / printers and others. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the notes on the back before filling this page) PVC has excellent economic efficiency, embossability, formability and other. However, because it generally contains a large amount of plasticizer and its film is soft, the plasticizer will penetrate the surface over a long period of time, and the problem of environmental degradation due to the generation of hydrogen chloride during combustion. Therefore, after investigation, polyolefin resins containing polyethylene or polypropylene as the main component are alternatives to polyvinyl chloride. Films made of these resins individually have excellent embossability, chemical resistance, etc., and are harder than plasticized polyvinyl chloride resins. However, when a polyvinyl chloride resin is laminated and formed with a thin sheet of gold tincture, a part thereof is whitened, thereby causing serious damage to a decorative design. Furthermore, there is a case where a rubber component is mixed into a polyolefin resin in order to prevent whitening. In this way, the softness of the manufactured film is in accordance with the standard of plasticized polypaper. The Chinese national standard (CNS) Α4 specification (210 X 297 mm) is applicable to the staff consumer cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. DESCRIPTION OF THE INVENTION (>) Vinyl chloride is the same. Furthermore, thermoplastic acrylic resins and fluoride resins each have unique characteristics-however, the films of these resins are as soft as ... plasticized polyvinyl chloride. In recent years, biaxially stretched polyester films containing polyethylene terephthalate (PET) as a main component are worthy of being regarded as substances for use with metal sheet calendars. Because the biaxially stretched polyester film is hardened, it has excellent film damage resistance (breakage, cracking, etc.). However, in the forming portion of the laminate, the adhesion of the PET film to the metal sheet is liable to deteriorate because the strength of the film is too high. Furthermore, there is a disadvantage in that it is a polyester film decorative design that cannot be biaxially stretched by forming uneven patterns by embossing. [Problems to be Solved] As mentioned above, various resins including plasticized polyvinyl chloride metal are used as office appliances such as electrical / electronic devices, audio devices, office appliances such as photocopiers / printers and others Box or interior parts. However, in each case, there are various disadvantages. Therefore, it is desired that the metal sheet covered with K resin has high strength and excellent formability, and "a" can be given a decorative design by embossing. The object of the present invention is to overcome the shortcomings of the conventional metal sheet covered with K conventional resin, and to provide a metal sheet covered with polyester resin, in which embossed resin is given a decorative design with high strength and excellent formability. .

Description of the invention (W) Furthermore, in the present invention, the basic physical properties of the polyester resin and the metal sheet covered with polyester tooth grease are examined in detail. Of characteristics. As a result, a crystalline property of the frown tree I is a major factor that greatly controls the properties of the metal sheet covered with the M resin. X-ray, differential scanning calorimeter (DSC), density and other methods are commonly used to evaluate the crystallinity of polyester. The crystallinity is affected by the heat treatment conditions and the resin temperature, and the poly (p-parapeptide) and / or poly (p-peptide) (these are crystalline resins) usually reach 30 to 50X. When the polyester resin is formed by copolymerization as described above, the degree of crystallinity decreases, depending on the type or compound amount of the polyacid or polyol, and in some cases, a resin with low crystallinity or no crystallinity can be obtained Resin. Therefore, it is difficult to accurately distinguish a crystalline polyester resin from a low crystallinity resin or a non-crystalline polyester resin. Therefore, in the present invention, when the resin is hot-melted, then quenched and thereafter, the resin temperature K1GC / min rises, and when the resin is melted then the resin M1Q 1 / min is lowered to room temperature. As shown in Figures 1 and 2, the resin that clearly shows the exothermic peak due to resin crystallization and the endothermic peak due to resin melting in differential scanning calorimetry (DSC) is called a crystalline polyester resin . Resin * Among them, in the same differential ~ scanning calorimeter (DSC), the exothermic peak caused by the crystallization of the resin and the endothermic peak caused by the melting of the resin are shown * As shown in Figure 3, it is regarded as Resin with low crystallinity or non-crystalline resin. Here, the ripening peak temperature shown at the rising temperature is usually referred to as the low temperature crystallization temperature (T C 1), and the endothermic peak temperature shown at the falling temperature of the resin molten state is generally referred to as the high temperature crystallization temperature (T C 2).

Description of the invention (j) " Crystalline resins have lower low temperature crystallization temperature (TC 1) and higher " high i crystallization temperature (TC 2). In the case of poly-butene, the low-temperature crystallization temperature (T C 1) is not clearly displayed, but the high-temperature crystallization temperature (τ C 2) is shown to be close to 2 0 0 υ. On the other hand, in a resin having a low crystallinity or a resin having no crystallinity, an endothermic peak system due to crystallization is not clearly shown. In the present invention, the influence of the blending ratio of the crystalline polyester resin and the low crystallinity resin or the non-crystalline resin on the metal sheet covered with the M resin is examined. Results * It was found that polyester resins mainly composed of crystalline polyester resins and containing low crystallinity or non-crystalline resins have high hardness and excellent impact-formability, embossability, and embossed heat resistance, The crystalline polyester resin is preferably blended with a low-crystalline resin or a non-crystalline resin having a weight of 5 to 50. When the resin has a low crystallinity or a blending ratio of less than 5% by weight, a blending effect cannot be obtained. On the other hand, when the blending ratio thereof exceeds 40% by weight X, it is not suitable because the heat resistance of embossing is lowered. Furthermore, the crystalline polymer resin is preferably one having an exothermic peak caused by resin crystallization above the glass transition temperature (Tg) and below 1 7 Q υ.

In some cases * a primer or adhesive can be placed between the metal sheet and the polyester resin layer. Furthermore, a colored layer may be provided as an upper or lower layer of the polyester resin layer. In addition, as a method for obtaining a metal sheet covered with a polyester resin, a method usable in the present invention is to use a device such as an extruder to directly extrude the hot-melt resin onto the metal sheet, and then extrude it. An embossing roller causes an uneven pattern on the extruded resin when the resin is in a hot-melted state, or another method is available in which a device such as an extruder is used to extrude-mold the hot-melted resin K The resin film is completed, and then the extrusion-molded film is laminated with the metal sheet ^ Both of the above methods are suitable for the purpose of the present invention.
