Problems solved by technology

The protective resin coated on the outer layer can be changed according to different requirements. In order to meet the high hardness requirements of the outer protective layer, nano or micro particles of high hardness inorganic oxides can usually be added to the resin formula; however, this Although additives can improve the hardness and wear resistance, it is easy to cause poor elongation and formability, and also cause problems such as rough appearance and tactility.
[0007] Furthermore, products with fluffy touch in the prior art use more complex processing techniques, such as corona, or electrostatic flocking processing, or the production of fluffy materials bonded to plastic substrates, which not only has high fixed costs but also The process is complicated and time-consuming, and the biggest problem is the poor bonding between the elastic fluff layer and the plastic substrate

Embodiment Construction

[0028] see Figure 1 to Figure 4 As shown, the film structure of the present invention can be applied to the in-mold decoration (In Mold Decoration, IMD) process, as 3C home appliance casing, automobile interior or audio casing, toy casing, video game joystick, keyboard, mouse, various grips , handle shell... and any high-value-added products that require colorful or 3D decoration technology and a comfortable feel. The film structure includes: a film 10 , a coating 20 , an ink layer 30 and a plastic substrate 40 .

[0029] The film 10 is transparent and its thickness is about 80-500 μm. The material of the film 10 is selected from acrylic (PMMA), polycarbonate (PC), polyethylene terephthalate (PET) , polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), methyl methacrylate and styrene copolymer (MS), triacetyl cellulose (TAC) and cyclo One of the olefin copolymers (COC).

[0030] The coating 20 includes a colloid 21 and at least two kinds of flex...

Abstract

The invention discloses a thin film structure and a manufacturing method thereof for intromode decoration process. The method comprises the steps of coating a coating containing at least two kinds of elastic resin particles on the surface above the thin film, wherein the two kinds of resin particles contains first resin particles for increasing the fluffy feeling and second resin particles for increasing the scratch and abrasion resistances, then forming an ink layer on the surface below the thin film and molding the thin film into a predetermined shape through thermal treatment, molding and laminating a plastic base material under the ink layer in the form of injection molding, and finally hardening the coating by using ultraviolet light. Hereby, the thin film has fluffy feeling as well as scratch and abrasion resistances.

Description

technical field [0001] The invention relates to a film structure and a manufacturing method thereof, in particular to a film structure and a manufacturing method thereof which are used in an in-mold decoration process and have a special fluffy touch and have anti-scratch and wear-resistant properties. Background technique [0002] As technology products are widely used in daily life, more and more product demands have been upgraded from general functionality to high value-added products with both texture and appearance. [0003] Products with traditional colorful appearance are mostly made by ink color registration. Since the ink layer is used as the outermost protective layer of the product, its color will be lost with long-term friction, resulting in fogging or fading, and may also cause peeling and loss. its protective properties. [0004] The production process of ink registration is to apply various patterns or colors on the surface by spraying. When spraying and color...
