Problems solved by technology

Giving plastic metal luster and appearance by electroplating process is the main surface treatment technology at present. However, the wet electroplating process has the following disadvantages: (1) high water and energy consumption; (2) a large amount of waste water (mainly containing heavy metal ions) , cyanide, acid-base and organic pollutants) and toxic waste gas (mainly containing all kinds of acid mist and dust); (3) easy to cause fire and cause heavy losses
Therefore, under the dual pressure of energy and environmental problems, the development of wet electroplating technology is also seriously hindered in the global trend of energy saving, emission reduction and consumption reduction due to its serious pollution to the environment and damage to human health.

Embodiment 1

[0026] In this embodiment, the base material of the decorative part is PC, and there is a groove on the rear surface of the substrate. The groove is covered with a chromium coating with a thickness of 10nm and a diamond-like coating with a thickness of 200nm from the inside to the outside. Inductive visible light sources arranged in a certain shape.

[0027] The method for preparing the surface coating of the above-mentioned automobile trim comprises the steps of:

[0028] Step 1: Suspend the plastic substrate on the metal support and place it in a vacuum chamber. Introduce Ar gas so that the pressure in the chamber is 0.2Pa. Set the power of the ion source of the anode layer to 150W to ionize Ar, and apply to the metal support Pulse negative bias voltage -50V, use argon ion beam to etch the surface of the substrate, and the etching time is 5min;

[0029] Step 2: Introduce Ar gas into the coating chamber so that the pressure in the chamber is 0.3Pa, turn on the DC magnetron s...

Abstract

The invention discloses a car trim and a preparation method of a surface coating of the car trim. The trim comprises a plastic substrate, wherein the plastic substrate is transparent to visible light; the back surface of the substrate is provided with a groove; the groove is internally covered with a nano metal coating and a diamond-like coating from interior to exterior; and an outermost layer is provided with induction type visible light sources which are arrayed according to a certain shape. The invention also provides the preparation method of the surface coating of the car trim. The preparation method of the surface coating of the car trim comprises the following steps of (1), carrying out bombardment on a base material by adopting an Ar ion beam; (2), depositing the nano metal coating by adopting direct-current magnetron sputtering; and (3), depositing a hydrogen-containing diamond-like coating by adopting an ion source. Through the above preparation method of the surface coating, on one hand, a plastic material is enabled to have a silvery white metal appearance, and on the other hand, when the light sources on the back surface of the substrate are lit, a luminous pattern can be seen from a frontal surface; the method is green and environment-friendly; and the zero emission of a pollutant to an environment is achieved.

Description

Technical field: [0001] The invention relates to an automobile decoration part which has a silver-white metal appearance and can transmit light and a surface treatment method thereof. Background technique: [0002] In the modern automobile industry, plastic metallization is the main component of automobile decoration, and high-end decoration is a symbol of vehicle grade. Giving plastic metal luster and appearance by electroplating process is the main surface treatment technology at present. However, the wet electroplating process has the following disadvantages: (1) high water and energy consumption; (2) a large amount of waste water (mainly containing heavy metal ions) , cyanide, acid-base and organic pollutants) and toxic waste gas (mainly containing various types of acid mist and dust); (3) easy to cause fire and cause heavy losses. Therefore, under the dual pressure of energy and environmental issues, the development of wet electroplating technology is seriously hindere...
