Embodiment 1

[0013] Embodiment 1: plastic substrate cleaning and plasma treatment method

[0014] Plastic substrates such as ABS, PMMA, PE, and PP are placed in deionized water or absolute ethanol for ultrasonic cleaning, and the cleaned plastic substrates are dried and placed on the sample library in the plasma processing chamber, and then Vacuum the chamber to a degree higher than 6×10 -3 Pa, take out the plastic substrate on the sample library with a magnetic force transfer rod and place it on the plasma processor, then feed high-purity argon, nitrogen or a mixture thereof with a flow rate of 20-100 sccm into the cavity to adjust the pressure in the cavity 3 ~ 10Pa, the power applied to the plasma generator is 10W / cm 2 The RF power supply is used, and the processing time is controlled at 3 to 10 minutes. The processed plastic substrate is directly transferred to the sputtering chamber through the sample transfer device for deposition of metal or hard film.

Embodiment 2

[0015] Embodiment 2: Preparation of metal decorative film by radio frequency magnetron sputtering on PMMA plastic substrate

[0016] The purity of the chromium, nickel or titanium metal target for sputtering is 99%, and the relative density is ~0.98. The chromium, nickel or titanium target is correctly installed in the target gun, and the vacuum is pumped until the background vacuum of the sputtering chamber is higher than 2.0× 10 -4 Pa, take the PMMA plastic after the processing of embodiment 1 as the substrate, the substrate is not heated (water cooling is controlled at room temperature), and a certain amount of argon gas is passed into the sputtering chamber, and the pressure in the sputtering chamber is adjusted to be 0.2~5Pa, The RF sputtering power is adjusted to 20W / cm 2 , the deposition time is controlled to be 10-60 minutes, and the prepared metal film has a bright silver-white metallic luster.

Embodiment 3

[0017] Embodiment 3: Preparation of hard decorative film by radio frequency magnetron sputtering on ABS plastic substrate

[0018] The purity of titanium, titanium nitride, titanium carbide or titanium carbonitride targets for sputtering is 99%, and the relative density is ~0.96. The target is correctly installed in the target gun, and the vacuum is pumped until the background vacuum of the sputtering chamber is high. at 2.0×10 -4 Pa, with the ABS plastic substrate treated in Example 1 as the substrate, the substrate is not heated (water cooling is controlled at room temperature), and a certain amount of argon, helium, nitrogen, acetylene, methane is passed into the sputtering chamber or its mixed gas, adjust the pressure in the sputtering chamber to 0.5-8Pa, and adjust the RF sputtering power to 15W / cm 2 , the deposition time is controlled at 5-80 minutes, and the prepared hard film is golden yellow, black, blue or silver gray.

Abstract

The invention relates to a method for depositing a metal or hard ornament film on a plastic substrate. In the method, the metal or hard ornament film is prepared on the surface of a plastic substrate material by using a radio frequency magnetron sputtering technology, and good binding force exists between the prepared ornament film and the substrate. The plastic substrate material comprises ABS plastic (terpolymer of acrylonitrile-butadiene-styrene), PMMA (polymethyl methacrylate) organic glass, PE (poly ethylene) plastics, PP (polypropylene) plastics and the like. The metal ornament film comprises chromium, nickel, titanium, aluminum, aurum, silver, iridium or alloys and the like, and the hard ornament film comprises metal nitrides, carbon compounds, oxides, diamonds and the like. The method has the advantages of simple operation, no pollution and low cost, and the prepared film is good in adhesive force.

Description

technical field [0001] The preparation method involved in the invention belongs to the technical field of decorative materials. Background technique [0002] Plastic is a lightweight material with low price, good chemical stability, good corrosion resistance, rigidity and processability. Based on the above advantages, metal materials have been gradually replaced by plastics in many fields. However, compared with metal materials, the plastic surface generally does not have metallic luster, so that the decorative performance of plastic products is not satisfactory. In order to improve this limitation of plastic products, people have done a lot of work to modify the plastic surface. Covering a layer of metal film or hard film on the surface of the plastic product can not only improve the surface wear resistance of the plastic product, but also improve the appearance of the plastic product and improve its ornamental performance. At present, acid treatment or monomer treatment...
