201018581 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to an in-mold decorative molding process in which a multifunctional plastic is applied to the manufacturing method, and in particular, a process of performing a molding step. 3 Pre-stones [Prior Art] Traditionally, the process of improving the surface properties and added value of plastic products is better than metal-layer or artificial leather. Spraying and painting are used as surface coating eyebrows. # 2二暴材次 Consider the durability of the above (4) layer and «Silk's adhesive energy, which affects the durability of the product. In this way, the production also has the effect of protective film, and the appearance color variability and selection. 'Can't make colorful and complicated lines or 3D special effects. If you want to enhance the surface of the special grain hand multi-channel paint spraying process after the above-mentioned bonding step, it is not only difficult to (4) uneven coating.

In Mold Decoration / owning, the integration of injection molding and assembly is achieved, and various effects can be made, which are very decorative and functional. In order to improve the surface physical properties and decorative properties of IMD 201018581, such as improving the surface hardness of the film, and imparting a special image and structure to the surface of the thin M surface, the surface of the plastic film of the generation is coated with a special functional coating. It has become a subject of 1MD production application. At present, the film commonly used in the industry is a film of the process of (10). The procedure includes coating a special coating on the upper surface of the plastic material, and thermally hardening the surface to achieve surface hardening, and printing on the surface of the lower surface _ _ F 〇 rm_ molding, and ► ^ ^ t shot to make the final difference, and finally UV light hard to make the surface of the product to high hardness and high wear resistance. However, the disadvantage of =cure is that it must go through two hardening procedures, which will consume more than one parent: the time and the fixed cost; and the plastic film in the ultraviolet hard f's table, the wear resistance characteristics are very poor, easy to cause H Also prepared #人工作(4) Cheng Lang is damaged and the guiding material is poor, the raw yield is greatly reduced; on the other hand, the final hardening step is in the most productive step, and then the downstream application end (such as the shell manufacturing must After the shape of the outer casing is formed, the resin hardening step is carried out, so that the downstream material must be light-hardened, thereby causing an increase in the cost of the lower (four) business, and finally, the process cost of the outer casing molding factory is increased. The team moved the hardening step to the molding step before using the non-extensible resin. Coating the tree in a discontinuous manner also caused complicated processing, while the discontinuous resin film also made the outer protective function poor. The reason is that the present invention is capable of improving the above-mentioned defects, and proposes a present invention which is reasonable and effective in improving the above-mentioned defects. Further ten 201018581 [Invention content] a main purpose of this month is to provide a multi-functional plastic film coating: method and application of the manufacturing method of the in-mold decorative molding process, the manufacturing method can provide a high elongation resin layer molding material First, the hardening step of the resin is carried out, and then the process is carried out. - The film is not like _ _ material. After the film is formed, there is no need to apply a bit of the mouth. Therefore, the process has a simplified process and a cost saving effect; and the zebra, the special graphic and the texture feel are Highly anti-wear, knowing, is a multi-functional protective film. - In order to achieve the above purpose, the present invention provides a multifunctional plastic::: system;: method, the steps are as follows: Step -: provide - plastic film: Two: a main cloth a polymer coating on the upper surface of the plastic film; and / step two.

An in-mold decorative molding process using a method for manufacturing a multifunctional plastic film, comprising the steps of: Step 1: providing a plastic film; Step 2: coating a polymer coating on the upper surface of the plastic film; Three: hardening the polymer coating to form a malleable tree 26 201018581 Glue: sheet: upper surface, the plastic film and the tree wax: the structure is formed - a malleable plastic film, and the plastic film is formed There are a plurality of patterns; less "Step 4: coating an ink layer on the lower surface of the plastic film; Step 5: forming the ductile plastic film into a pre-form; and, y step 6. Shooting a plastic In the lower surface of the plastic film. 1 〇, as in the in-mold decoration molding process described in claim 9, wherein the plastic film is polyethylene terephthalate (PET). Polycarbonate (PC), Triacetonitrile Cellulose (TAC) ^Polymethylmethacrylate (P-A), Methyl methacrylate Benzene Methylmethacrylate styrene or Cyclic Olefin Copolymer (C0C), and the thickness of the plastic film is 1 〇 to 1 〇〇〇 micrometer (em). The in-mold decoration molding process according to Item 10, wherein the polymer coating is an ultraviolet curing resin or a thermosetting resin. 1. The in-mold molding as described in claim 11 The process of the ultraviolet curing resin includes a Ful 1 acrylate resin, a p〇iyester acrylate oligomer, and an Epoxy acrylate oligomer. Any one or two of the polyurethane acrylate oligomers 27 201018581 O^umhane acryiate oilg (10) er), and the ultraviolet light curing resin is uniformly dispersed in the diluted monomer 1% as in the patent scope item 12 The in-mold decorative molding system comprises: a monofunctional reactive monomer, a dual-functional = reactive monomer, a trifunctional reactive monomer, a polyfunctional ruthenium single limb or both the above. Cheng such as: two special: in-mold decoration of the first three steps in the range of three lines forming system provided - ultraviolet light - Mi foreign money energy light curing resin. The in-mold decorative molding pin-hardening resin described in Item No. 11 of the patent scope includes acrylic polyol resin, ::: resin, polyamidamine resin, poly-imine resin, water resin, phenol resin. , epoxy resin. The in-mold decoration molding process described in Item 15 of the 6th paragraph of the benefit range causes the heat-curing 1 grease heat-hardening step to be performed at a predetermined temperature in the in-mold decoration molding process as described in Item 11 The second step further includes a step of adding and dispersing the powder particles to the coating. The mold-forming structure structure described in Item No. 11 of Section C is the in-mold decoration molding system described in Item ii of the claim sect. Step 5 is to form the predetermined shape by using a high-pressure molding or a plastic film having a ductility and ductility. The method of sputum is as follows: In the in-mold money molding system described in claim 1 of the patent application, in the sixth step, the plastic is molded by injection molding, and is attached to the lower surface of the plastic film.
