Abstract
The invention discloses a kind of photosensitive glass-ceramics shell, it is characterised in that：It is made up of according to parts by weight the following raw material：40 60 parts of silica, 26 38 parts of lithium carbonate, 5 20 parts of potassium nitrate, 39 parts of aluminum oxide, 0.2 0.7 parts of calcium oxide, 2.5 9 parts of zirconium, 0.1 10 parts of graphene.The present invention adds graphene in the preparation formula of traditional devitrified glass, greatly improves the intensity, pliability and heat conductivility of devitrified glass.
Description
Technical field
The present invention relates to the application of photosensitive glass-ceramics, and in particular to a kind of photosensitive glass-ceramics shell and preparation method thereof.
Background technology
It is well known that the atomic arrangement inside simple glass is that do not have well-regulated, one of the reason for this is also Glass breadks easily.
Glass ceramics (i.e. devitrified glass) has the double grading of glass and ceramics, and glass ceramics is made up of as ceramics crystal,
Its atomic arrangement is very regular, and therefore, glass ceramics is higher than the brightness of ceramics, stronger than glass toughness, prior art
In to have recorded using zirconium oxide be that main component makes mobile phone shell, but zirconium oxide mobile phone shell yield rate is low, and bulk density is big, heat
Curved probability is poor, and crash resistance is poor, therefore generally requires to realize plus frame on the basis of zirconium oxide, and adds after frame due to office
Portion's stress, it is easier to damage zirconium oxide body.Corning Incorporated have developed photosensitive glass-ceramics, but have no in the prior art
Photosensitive glass-ceramics perfection is agreed with into the record on the frangible Electrical articles such as mechanical, electrical brain in one's hands, in addition, for the heat of devitrified glass
Crook is managed and flanging handling process, and successful is not broken through.The present invention adds graphene in devitrified glass.Graphene has
There are very good intensity, flexible, heat conductivility, added in devitrified glass after graphene, devitrified glass can be greatly improved
Intensity, pliability and heat conductivility.
The content of the invention
