Problems solved by technology

In the past, there are generally three techniques to achieve this. One is to mix special metal toner in plastic resin to prepare, but the effect of this metal texture is poor, and it is mainly matte; the other is to use electroplating, but electroplating gives The pollution of the environment is relatively large, and the electroplating is limited to hard chromium plating, which cannot form a colored metallic luster; the third method is to use the reactive sputtering method to inject oxygen into titanium oxide while sputtering titanium, but the required sputtering It takes a long time and it is not easy to master the process, and the cost is high

Embodiment Construction

[0011] Please refer to Fig. 1, a kind of treatment method of plastic surface with colorful titanium metal texture, it comprises the following steps:

[0012] Step 1: Ultrasonic cleaning is performed on the surface of the plastic part 1 .

[0013] The principle of ultrasonic cleaning is that the high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated into the medium cleaning solvent. The ultrasonic waves radiate forward in the cleaning liquid, making the liquid flow And tens of thousands of tiny bubbles are produced. These bubbles form and grow in the negative pressure zone where the ultrasonic wave travels longitudinally, and close quickly in the positive pressure zone. In this process called "cavitation" effect, the bubble closure can form an instantaneous high pressure of more than 1000 air pressures, and the continuous generation of instantaneous high pressure is like a seri...

Abstract

The invention discloses a disposing method of plastic surface with colorful titanium metal sense, which comprises the following steps: 1. cleaning the surface of plastic surface; 2. coating a layer of bottom paint with thickness at 5-10um on the plastic surface to display little bright or foggy; solidifying through UV; 3. plating a layer of titanium metal at splashing pattern; 4. adopting plastic of splashed titanium film as anode through anode oxidizing technology and stainless steel as cathode; supplying different voltages in the electrolyte to obtain different colors of colorful metal film.

Description

technical field [0001] The invention relates to a plastic surface treatment method, in particular to a plastic surface treatment method with colorful titanium metal texture. Background technique [0002] Now many products hope to form a colorful titanium texture on the plastic surface to achieve an aesthetic effect. In the past, there are generally three techniques to achieve this. One is to mix special metal toner in plastic resin to prepare, but the effect of this metal texture is poor, and it is mainly matte; the other is to use electroplating, but electroplating gives The pollution of the environment is relatively large, and the electroplating is limited to hard chromium plating, which cannot form a colored metallic luster; the third method is to use the reactive sputtering method to inject oxygen into titanium oxide while sputtering titanium, but the required sputtering It takes a long time and it is not easy to master the process, and the cost is high.
