Embodiment 1

[0023] (1) Use ABS, PC / ABS material panel parts as covering parts, spray a colorless and transparent primer on the front side of the panel parts, light curing or heat curing is completed, and the thickness is 15 microns;

[0024] (2) Subsequent metallization treatment is carried out on the surface of the color pattern, that is, the panel parts are placed in 1.2×10 -2 Pa~2.0×10 - 2 In the vacuum environment of Pa, the metal layer (In / Sn) is attached to the back side of the panel by physical vapor deposition (PVD), and its thickness is 50 nanometers; in the same vacuum environment, plasma chemical vapor deposition (PECVD) is carried out The non-metallic layer (Nb 2 o 5 / SiOx) is attached to the backside surface of the panel member and covered with a metal layer with a thickness of 80 nanometers;

[0025] (3) After the metallization is completed, a colorless, transparent or colored protective paint is sprayed, and light curing or heat curing is completed, and the thickness is...

Embodiment 2

[0027] (1) Use the transparent PC panel part as the cover part, spray a transparent hard coating on the front side of the panel part, light curing or heat curing is completed, and the color pattern is set on the back side by hot stamping;

[0028] (2) Subsequent metallization treatment is carried out on the surface of the color pattern, that is, the panel parts are placed in 1.2×10 -2 Pa~2.0×10 - 2 In a vacuum environment of Pa, a metal layer (In / Sn) is attached to the back side of the panel with a thickness of 30 nanometers by physical vapor deposition (PVD); in the same vacuum environment, plasma chemical vapor deposition (PECVD) is carried out The non-metallic layer (Nb 2 o 5 / SiOx) is attached to the backside surface of the panel member and covered with a metal layer with a thickness of 150 nanometers;

[0029] (3) After the metallization is completed, spray a colorless, transparent or colored protective paint, which is light-cured or heat-cured, with a thickness of 20...

Embodiment 3

[0032] (1) Use the transparent PC panel as the cover, spray a transparent hard coating on the front side of the panel, light curing or heat curing is completed, set the color pattern on the back side by hot stamping or printing ink, and then spray colorless and transparent Primer, light-cured or heat-cured, with a thickness of 25 microns;

[0033] (2) Subsequent metallization treatment is carried out on the surface of the color pattern, that is, the panel parts are placed in 1.2×10 -2 Pa~2.0×10 - 2 In the vacuum environment of Pa, the metal layer (In / Sn) is attached to the back side of the panel by physical vapor deposition (PVD), and its thickness is 30 nanometers; in the same vacuum environment, plasma chemical vapor deposition (PECVD) is carried out The non-metallic layer (Nb 2 o 5 / SiOx) is attached to the backside surface of the panel member and covered with a metal layer with a thickness of 150 nanometers;

Abstract

The invention relates to a manufacturing method of a covering piece having a function of an adaptive cruise control system of a vehicle. The manufacturing method comprises the following steps of usinga panel piece as the covering piece, and setting colored patterns on the front side or the back side of the panel piece; then performing vapor deposition on the surface of the colored patterns in a vacuum environment to form a metal layer and a nonmetallic layer, wherein the metal layer is covered by the nonmetallic layer; and finally protecting the metal layer and the nonmetallic layer, so as toobtain the covering piece. The covering piece manufactured by the manufacturing method disclosed by the invention can realize the appearance effect of metal mirror surface or matte metallic luster ora plurality of colored patterns, two-way penetrating of radar waves is effectively met, and the covering piece can be applied to marks of auto makers, grating decorative cover plates, grating decorative strips and the like.

Description

technical field [0001] The invention belongs to the field of automobile signs, and in particular relates to a preparation method for a cover with the function of an automobile active cruise radar system. Background technique [0002] Car signs are widely used on various types of cars because of their appearance decoration and identification functions. The ACC system is the adaptive cruise control system. The system adjusts the vehicle to follow the vehicle at a safe distance according to the driving status of the vehicle in front. When there is no vehicle in front, the vehicle drives at a constant speed set by the driver. The car label is assembled on the front of the vehicle, covering the front radar in the ACC system, and the part where the radar wave passes does not hinder the emission and reflection of the radar wave. [0003] But at present effectively satisfy the two-way penetrating car label of radar wave and still leave blank. Contents of the invention [0004] T...
