Problems solved by technology

[0003] The commonly used material for the existing shifter panel is PC, which adopts the process of injection molding and spraying light-transmitting paint, but there are defects such as poor light transmission of character lights, difficulty in ensuring uniformity of light transmission, and poor appearance and vision
[0004] There are also other materials used to prepare the shifter panel, but there is still the defect that the light penetrates and interferes with each other between the laser-engraved characters, which affects the functionality and aesthetics of the shifter panel.
Since the light penetrates and interferes with each other between the laser-engraved characters, it is necessary to increase the number of light-guiding and light-shielding parts, which leads to an increase in the number of light-guiding and light-shielding parts and their molding molds, and the cost increases

Abstract

The invention discloses a shifter panel material for preventing light penetration interference and a preparation method of apanel. The panel material is prepared from the componentsin parts by weight:100 parts of PC / ABS plastic alloy,0.3~2 parts of PET, 0.03~0.1part of a compatibilityagent, and 0.1~0.6 part of a photo-stabilizer. The panel material can prevent light penetration interference and improve the scattering of the panel material to the light source.The preparation method of the panel comprises granulation, injection molding, electroplating and radium carving. According to the preparation method, operation is easy, and production efficiency is high.

Description

technical field [0001] The invention relates to a shifter panel material and a preparation method of the panel, in particular to a shifter panel material and a preparation method of the panel that prevent light penetration and interference. Background technique [0002] Vehicle safety, appearance and lightweight body are the current development trends of new energy vehicles. Therefore, higher requirements are put forward for the environmental protection, weather resistance and processability of the materials selected for the automobile central control system. For the light and thin shifter panels that are electroplated and light-colored after laser engraving, the phenomenon of mutual penetration and interference of lights at the characters is often prone to occur. Therefore, it is necessary to improve the scattering properties of the material to the light source. [0003] The common material of the existing shifter panel material is PC, which adopts the process of injection...
