Abstract

The invention provides a meter panel surface shield composition, a meter panel surface shield, and a preparation method of the surface shield. The meter panel surface shield comprises a polymer resin and an organic dye, wherein the polymer resin is selected from one or more of polymethyl methacrylate, polycarbonate or a cycloolefin copolymer; the organic dye is selected from one or more of a phthalocyanine dye, a halogenated phthalocyanine dye, a perylene dye, a qinacridone (qinacrididone) dye, a diketopyrrolopyrrole dye, a dioxazine dye, a quinophthalone dye, a benzidine dye, an isoindole dye, a benzimidazolone dye, an anthraquinone dye, a pteridine dye and a condensed azo dye. The haze of the meter panel surface shield prepared from the composition is small, so it is convenient for clearly reading the indication of a meter panel.

Description

technical field [0001] The invention relates to an instrument panel mask composition, an instrument panel mask and a preparation method thereof. Background technique [0002] At present, the popularity of automobiles in daily life is getting higher and higher. In the current automobile industry, a large number of plastics have been used to replace various non-ferrous metals and alloy steels in order to improve the flexibility of automobile industry design, reduce the cost of parts processing, assembly and maintenance, and use plastics to produce automobile bodies and Components are also one of the main directions to achieve lightweight and energy-saving automobiles. [0003] As an important part of the car, the instrument panel mask needs to enable the driver to clearly see the readings on the instrument panel to provide protection for safe driving. At this time, it is required that the instrument panel mask has very good light transmittance and can be kept clear. In the ...
