Description

Technical Field

[0001] The present invention relates to the technical field of decorative films, and in particular to a high-gloss mirror gloss film and a preparation process thereof. Background Art

[0002] With the development of building decoration materials, more and more research has been done on integrated wall panels. Integrated wall panels are mainly made of decorative films and base panels. The appearance of the decorative film determines the appearance of the integrated wall panels. In order to achieve the decorative effect of stainless steel mirrors, mirror films with mirror effects have been developed and prepared.

[0003] Currently, mirror film production primarily involves coating a color layer on the substrate surface and then metallizing the back of the substrate to create a reflective layer, resulting in mirror-like decorative films with varying colors. The substrate is primarily made of PET, but the untreated PET surface is not completely mirror-flat. Direct metallization will not achieve a high mirror gloss, and coating the color layer on the substrate surface will also result in imperfections in the color layer's flatness, making it impossible to produce a mirror film with a higher gloss. Therefore, improvements are needed. Summary of the Invention

[0004] The present invention addresses the defects in the prior art in that a mirror film with higher gloss cannot be produced due to poor surface flatness of the substrate when producing the mirror film, and provides a new high-gloss mirror gloss film and a preparation process thereof.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] A process for preparing a high-gloss mirror-like gloss film comprises the following steps:

[0007] S1. Performing unwinding and coating operations on a substrate layer in sequence to obtain a mirror film semi-finished product with a coating primer layer. The substrate layer is made of PET, PMMA, PC, or ABS. During the coating operation, the coating speed is 7-20 m / min. The coating is a resin coating, which is composed of the following raw materials in parts by weight: 0-20 parts of a solvent, 0.5-2 parts of an initiator, and 60-80 parts of a polyurethane acrylate resin. The solvent is ethyl ester, butyl ester, or isopropyl butanone. The initiator is one or a mixture of the following: photoinitiator TPO, photoinitiator TPO_L, photoinitiator 184, photoinitiator 1173, or photoinitiator 907.

[0008] S2, performing radiation baking on the mirror film semi-finished product 1 to obtain a mirror film semi-finished product 2;

[0009] S3, performing mirror roller pressing and curing operations on the mirror film semi-finished product 2 to adjust the flatness of the coating base coating layer until the pressure values ​​on the driving side and the operating side of the mirror roller are consistent, thereby obtaining a mirror film semi-finished product 3;

[0010] S4, performing a film application operation on the side of the mirror film semi-finished product 3 with the coating primer, performing a film rolling operation, and hanging and standing for 24 hours to obtain a mirror film semi-finished product 4;

[0011] S5, performing unwinding and film tearing operations on the mirror film semi-finished product 4, and performing metal coating operations twice on the side of the mirror film semi-finished product 4 with the coating primer layer, to obtain a mirror film semi-finished product 5 with a metal coating layer;

[0012] S6. Apply a protective coating to one side of the mirror film semi-finished product 5 having the metal coating layer, and apply a hardening layer to the other side of the mirror film semi-finished product 5 to obtain a high-gloss mirror gloss film with high-gloss mirror gloss.

[0013] The mirror rolling operation improves the defects and roughness of the substrate surface. The two consecutive metal plating operations make the coating thicker and denser, without pinholes, bubbles and other defects, so that the mirror gloss film has a higher gloss. The above steps protect the entire process of the mirror gloss film processing, reduce the occurrence of scratches and bruises on the mirror gloss film during the production process, and further improve the yield rate of the mirror gloss film.

[0014] Preferably, in the above-mentioned process for preparing a high-gloss mirror-finish film, a slit coating method is used when performing the coating operation in step S1.

[0015] Slit coating can be used to apply most resin coatings, for example, resin coatings without the addition of solvents can also be coated. Moreover, slit coating can accurately control the coating thickness and coating width.

[0016] Preferably, in the above-mentioned process for preparing a high-gloss mirror gloss film, in step S2, multiple groups of infrared lamps are used to radiation bake the mirror film semi-finished product, the radiation baking temperature is 50 degrees to 100 degrees, and the radiation baking time is 5 seconds to 20 seconds.

[0017] Radiation baking can not only accelerate the volatilization of the solvent, but also accelerate the self-leveling of the coating on the mirror film semi-finished product, thereby enhancing the mirror effect of the mirror film semi-finished product.

[0018] Preferably, in the above-mentioned process for preparing a high-gloss mirror gloss film, a mirror roller is used in step S3 to perform a mirror rolling operation on the mirror film semi-finished product 2, the surface of the mirror roller is made of hard chrome, and the hardness of the mirror roller is HRC56-HRC66.

[0019] The mirror roller is made of hard chrome with a hardness of HRC56-HRC66, which makes the mirror roller have super high wear resistance and super long service life; the mirror roller is used for mirror rolling operation to improve the glossiness of the mirror film semi-finished product.

[0020] Preferably, in the above-mentioned process for preparing a high-gloss mirror gloss film, in step S3, while performing the mirror rolling operation, a UV lamp is used to cure the mirror film semi-finished product 2, the curing temperature is 23 degrees to 55 degrees, and the curing time is 0.5 seconds to 1 second.

[0021] Carrying out UV curing operation at the same time as mirror rolling operation not only improves the production efficiency of mirror film, but also enables the semi-finished mirror film to be fully cured and meet the corresponding performance requirements; using UV lamp for curing operation has the advantages of environmental protection and high efficiency.

[0022] Preferably, in the above-mentioned process for preparing a high-gloss mirror-finished film, when the mirror-finished film semi-finished product 5 is subjected to a metal coating operation in step S5, the material of the metal coating is aluminum, silver or copper.

[0023] By selecting aluminum, silver or copper, mirror effects of different colors can be achieved, thereby improving the aesthetics of the mirror film.

[0024] Preferably, in the above-mentioned process for preparing a high-gloss mirror-finish film, in step S6, the protective coating is treated by flow coating with silicone oil; the hardening layer is made of polyurethane acrylate resin, and the coating speed of the hardening layer is 20 m / min-30 m / min.

[0025] The protective coating layer uses silicone oil to improve the smoothness of the metal coating surface and reduce the adhesion of dust and other substances to the metal coating surface. The hardening layer uses polyurethane acrylate resin with excellent temperature resistance, thermal stability, wear resistance and good adhesion, thereby improving the stability of the hardening layer fixed on the substrate layer and the protective effect on the substrate layer.

[0026] A high-gloss mirror-finish film is manufactured according to the above-mentioned preparation process of a high-gloss mirror-finish film, including a hardening layer, a substrate layer, a coating primer, a metal coating layer and a protective coating, wherein the hardening layer, substrate layer, coating primer, metal coating layer and protective coating are distributed from top to bottom.

[0027] The protective coating and the hardening layer improve the protection effect of the high-gloss mirror gloss film, and the coating primer improves the flatness of the substrate layer, making it easier to perform metal coating to obtain a metal coating layer with high gloss.
