Description
Technical field
The present invention relates to the application of photosensitive glass-ceramics, and in particular to a kind of preparation side of photosensitive glass-ceramics mobile phone shell
Method.
Background technology
It is well known that the atomic arrangement inside simple glass is one of the reason for not having well-regulated, 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, 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, bulk density is big, heat
Curved probability is poor, and crash resistance is poor, therefore generally requires to be realized 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 onto mobile phone, in addition, being processed for the hot bending treatment of devitrified glass and flanging
Technique, not successful breakthrough.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of low cost, easy processing, node index photosensitive crystallite high
The preparation method of glass mobile phone shell.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of preparation of photosensitive glass-ceramics shell
Method, it is characterised in that：Comprise the following steps：
(1) configured with silica, lithium carbonate, potassium nitrate, aluminum oxide, calcium oxide, zirconium as raw material, after the completion of by original
Material is placed in melting furnace and carries out being molten into solution；
(2) being sent at once after solution-cast is molded in annealing furnace carries out annealing for blank；
(3) blank is carried out into specification section using commercially available wire cutting machine；
(4) rough polishing is carried out to section and punching is processed as rectangle standard film；
(5) the side edge of rectangle standard film four is done into preset data hot bending on hot press and is processed as four flanging crude products；
(6) crude product is carried out into photo-irradiation treatment；
(7) crude product after illumination is carried out into Crystallizing treatment in baking furnace；
(8) and then carry out finishing polish mobile phone shell finished product is obtained.
Further technical scheme is that the raw material is formulated with following portions by weight composition：
Silica 40-60,26-38 parts of part lithium carbonate, potassium nitrate 5-20 parts, aluminum oxide 3-9 parts, calcium oxide 0.2-0.7
Part, zirconium 2.5-9 parts.
Further technical scheme is that the raw material is formulated with following portions by weight：
50 parts of silica, 32 parts of lithium carbonate, 10 parts of potassium nitrate, 4.5 parts of aluminum oxide, 0.5 part of calcium oxide, 3 parts of zirconium.
Further technical scheme is that fusion temperature is maintained at 1500-1600 DEG C in step (1).
Further technical scheme is that fusion temperature is maintained at 1580 DEG C in step (1).
It is using the beneficial effect produced by above-mentioned technical proposal：Implement the technology of the present invention and do not need special installation, only
Common industrial ceramics production equipment is needed, can be produced if melting furnace, wire cutting machine, hot press, baking furnace etc..Thrown with equipment
Money is saved, and production process is pollution-free, and added value of product is high, is a new technology being worth promoting, separately the advantages of energy-conserving and environment-protective
Outward, utilization scope of the present invention is wide, low cost, high yield rate, easy processing, and product thinness is up to 0.15mm, and wear-resisting, corrosion resistant
Erosion, high temperature resistant, electrical conductivity is high, thermal conductivity factor is big, and intensity is enough to avoid being broken into pieces, and the present invention compares the mobile phone shell of zirconium oxide,
Using integrally formed hot bending process, the effect of frame is instead of, it is very easily supporting with mobile phone, it is auxiliary without other structures
Help；, by four flangings into after mobile phone shell, outward appearance is beautiful, and performance is far longer than zirconium oxide product for this mobile phone shell photosensitive glass-ceramics.
