Photosensitive color changing plastic mobile phone shell

Abstract

The invention discloses a photosensitive color changing plastic mobile phone shell. The photosensitive color changing plastic mobile phone shell comprises polycarbonate on the uppermost layer, graphite fibers on the middle layer and inorganic silica gel on the lowest layer. The inorganic silica gel is prepared from silicon dioxide, sodium silicate and sulfacid. Polycarbonate accounts for 74-75% of the total weight of the photosensitive color changing plastic mobile phone shell, graphite fibers account for 4-6% of the total weight of the photosensitive color changing plastic mobile phone shell, and inorganic silica gel accounts for 19-22% of the total weight of the photosensitive color changing plastic mobile phone shell. The photosensitive color changing plastic mobile phone shell has the advantages of being non-poisonous, pervious to light, good in low-temperature characteristic and the like.

Description

technical field [0001] The invention relates to a plastic, in particular to a photosensitive color-changing plastic mobile phone casing. Background technique [0002] Early mobile phones were mostly made of ordinary engineering plastics, and the appearance was usually unmodified, just simple anti-slip patterns or spray paint. Although it is very practical, it cannot satisfy consumers' psychology of advocating beauty. In the following mobile phones, many mobile phones use gorgeous materials to decorate the appearance of the mobile phone. Among them, the piano paint has been welcomed by the public. The piano lacquer process is a kind of baking varnish process. The process is very complicated, and the mechanized piano varnish is still very fast. Some mobile phone manufacturers use piano lacquer technology to manufacture, while others use ordinary polyurethane paint to spray paint, which is much worse in terms of craftsmanship and durability. The piano paint process gives pe...
