Glass-ceramics (i.e., glass-ceramics) has dual characteristics of glass and ceramics, and glass-ceramics is composed of crystals like ceramics, and its atomic arrangement is very regular. Therefore, glass-ceramics is brighter than ceramics and tougher than glass. Strong. It is recorded in the prior art that zirconia is used as the main component to make mobile phone cases, but the yield of zirconia mobile phone cases is low, the volume density is high, the probability of hot bending is poor, and the drop resistance is poor. Therefore, it is often necessary to add zirconia on the basis of zirconia. The upper frame is realized, and after adding the frame, due to local force, it is easier to damage the zirconia body
Corning Corporation of the United States has developed photosensitive glass-ceramics, but there is no record of perfectly fitting photosensitive glass-ceramics to mobile phones in the prior art. In addition, there is no success in the heat-bending and edge-folding processes of glass-ceramics. breakthrough

preparation example Construction
[0025] The invention describes a method for preparing a photosensitive glass-ceramic mobile phone case, which is characterized in that it comprises the following steps:
[0026] (1) Configure silicon dioxide, lithium carbonate, potassium nitrate, aluminum oxide, calcium oxide, and zirconium as raw materials. After the mixing is completed, the raw materials are placed in a melting furnace to be melted into a solution;
[0027] (2) Immediately send the solution to the annealing furnace for annealing treatment after casting the solution to be a billet;
[0028] (3) Carry out specification slicing with blank utilizing commercially available wire cutting machine;
[0029] (4) Roughly polishing and punching the slices into rectangular standard slices;
[0030] (5) The four edges of the rectangular standard sheet are processed into a four-fold rough product by pre-setting data heat bending on the hot press;
[0031] (6) Carry out light treatment to crude product;
[0032] (7) Carr...
Embodiment
[0040] Example, using 50 parts of silicon dioxide, 32 parts of lithium carbonate, 10 parts of potassium nitrate, 4.5 parts of aluminum oxide, 0.5 parts of calcium oxide, and 3 parts of zirconium as raw materials, the photosensitive glass mobile phone case was prepared according to the above steps, and a total of 10 parts were prepared. individual such as figure 1 For the samples shown, each sample is tested for experimental mechanical properties, using equipment: INSTRON-5566 universal material testing machine Vickers / microhardness tester; the test results are as follows:

Abstract
The invention discloses a method for preparing a photosensitive glass-ceramics mobile phone shell and relates to application of photosensitive glass-ceramics. The method disclosed by the invention comprises the following steps: configuring silicon dioxide, lithium carbonate, potassium nitrate, alumina, calcium oxide and zirconium serving as raw materials, and placing the raw materials in a melting furnace to be molten into a solution; performing cast molding on the solution, immediately feeding the solution into an annealing furnace, performing annealing treatment on the solution to become a preform body; performing specification slicing on the preform body by using a commercially available wire cutting machine; performing rough polishing on the slices, and performing punching treatment to obtain rectangular standard slices; performing preset data hot-bending shaping on four edges of the rectangular standard slices on a hot press so as to obtain a four-fold crude product; performing illumination treatment on the crude product; performing crystallization treatment on the illuminated crude product in a calcining furnace; performing fine polishing, thereby obtaining the finished mobile phone shell. According to the method disclosed by the invention, the utilization range is wide, the thickness can reach 0.15 mm, and the mobile phone shell is wear / corrosion-resistant, high in electric conductivity and high in heat conductivity coefficient, and has enough strength to be prevented from being smashed to pieces. In addition to the mobile phone shells, the technology disclosed by the invention can be further applied to circuit boards, aerospace engineering and military defense projects.
Description
technical field [0001] The invention relates to the application of photosensitive glass-ceramic, in particular to a method for preparing a photosensitive glass-ceramic mobile phone case. Background technique [0002] As we all know, the arrangement of atoms in ordinary glass is irregular, which is one of the reasons why glass is fragile. Glass-ceramics (i.e., glass-ceramics) has dual characteristics of glass and ceramics, and glass-ceramics is composed of crystals like ceramics, and its atomic arrangement is very regular. Therefore, glass-ceramics is brighter than ceramics and tougher than glass. Strong. It is recorded in the prior art that zirconia is used as the main component to make mobile phone cases, but the yield of zirconia mobile phone cases is low, the volume density is high, the probability of hot bending is poor, and the drop resistance is poor. Therefore, it is often necessary to add zirconia on the basis of zirconia. The upper frame is realized, and after addi...
