[0064] How to make plastic sheet

[0065] (1) Select an ABS base layer 1 with a thickness of 3mm, and bake it at 80°C for 8 hours to remove the stress of the base layer 1;

[0066] (2) Clean and remove impurities on both surfaces of the base layer 1 whose stress has been removed in step (1);

[0067] (3) For the base layer 1 cleaned in step (2), wipe the oil agent with an alkaline solvent, wherein the degreasing agent cannot affect the surface effect of the base layer.

[0068] (4) The surface of the base layer 1 after step (3) is degreased is activated by various activation techniques known to those skilled in the art, mainly roughening, sensitization, and three steps of activation, so that the surface of the base layer 1 forms a metal catalyst center.

[0069] (5) To the base layer 1 after step (4) activation, adopt electroplating technology known to those skilled in the art, plate one layer of chemical nickel film layer 7, wherein, electroplating condition is: nickel sulf...

[0081] How to make plastic sheet

[0082] (1) According to the same steps and methods as steps (1) to (9) of Example 1, a plastic sheet is made. The difference is that a layer of anti-plating ink is coated on the second surface of the base layer during pre-plating treatment.

[0083] (2) Dry the plastic sheet that has completed step (1) to obtain a plastic sheet plated with four metal layers of nickel, copper, tin, and chromium. Use EPYAG25 laser equipment with a current of 21A to engrave the desired pattern. 6. Adjust the depth of laser engraving by adjusting the current of the laser equipment. It is better to just expose part of the copper layer 2, part of the tin layer 3 and part of the base layer 1.

[0084] (3) Prepare the DSMT100P series metal paint 1, spray it on the reverse side of the material obtained in step (2) to obtain a film layer 9, and then bake it at 70°C for 2 hours, and the film thickness is 15 μm.

[0085](4) Spray a layer of polyurethane colored paint 5...

Abstract

The invention provides a sheet material. The sheet material comprises a base layer and pattern layers arranged on the surface of the base layer, wherein the base layer comprises a first surface and asecond surface, the first surface is at least provided with two pattern layers; the patterns are formed on each the pattern layer in sequence from the outermost layer to the base layer, and the patterns on the pattern layers are overlapped to show colorful metallic luster; the base layer may be a plastic layer or plastics-metal compound layer; and the second surface is also provided with the pattern layers. The sheet material has the colorful metallic third-dimensional decorative effect and meets the individualized needs of people. The invention provides the method for manufacturing the sheetmaterial, which is simple in process and can be easily implemented; and the invention also provides the electric product shell of the sheet material, which is widely used.

Description

technical field [0001] The invention relates to a sheet material, a manufacturing method thereof and a product casing. Background technique [0002] Some product casings, such as plastic sheets, are widely used in electronic products due to their advantages of light weight and low price. With the continuous development of the portable electronics industry, the trend of requiring metal texture on the surface of the casing of mobile phones, PDAs, MP3s, notebook computers, etc. is becoming increasingly obvious. The most common way to form the metal texture on the surface of the plastic shell is to electroplate or PVD (Physical Vapor Deposition) a metal layer on the plastic surface. With the improvement of the level, when people buy electronic products, they not only pay attention to the function and quality of electronic products, but also the personalized demand for electronic products has gradually become the main reason for purchasing electronic products. [0003] In the p...
