Abstract

The invention provides a jade imitated PC (Polycarbonate) material and a preparation method thereof. The jade imitated PC material comprises the following components in percentage by weight: 80-90% ofpolycarbonate, 5-15% of polymethyl methacrylate, 1-2% of a luminous agent, 0.5-1% of a fluorescent agent, 0.5-1% of a brightening agent and 1-2% of aids. The jade imitated PC material prepared by thepreparation method disclosed by the invention has a luminous effect, is high in light transmittance, bright in texture, clarified, enriched in delicate sense, high in surface gloss and bright in color, can give light in darkness for a long time by virtue of photo-induced energy storage, and the luminous duration reaches about 16 hours. Therefore, the jade imitated PC material has excellent application prospects and high application value.

Description

Technical field [0001] The invention belongs to the field of polymer materials and relates to a jade-like PC material and a preparation method thereof. Background technique [0002] There are all kinds of materials with various color effects on the market, which decorate the entire world. While pursuing beauty, it also considers the practicality of the materials, such as luminous materials, which glow in the dark. Due to the pursuit of environmental protection and aesthetics, materials with imitated jade, imitated marble, imitated gemstones, imitated flow lines or wood grain aesthetic resins were born. The materials of this series are dazzling and uneven in the market. The material with imitating jade effect not only gives people a refreshing visual effect in terms of luster, texture, bright, clear and delicate, and it can also emit green fluorescent effect for a long time at night. [0003] CN106147187A discloses a high-gloss halogen-free flame-retardant PC material and a prepar...
