Problems solved by technology

However, because the metal shell is easily corroded by corrosive media, the decorative film layer on the surface of the metal shell will fall off, seriously affecting its appearance; the anti-aging performance of the plastic substrate is poor; and the glass shell is fragile and difficult to form complex three-dimensional structure
In addition, none of the shells made of the above three materials has a warm and delicate feel like jade.

Embodiment Construction

[0013] The stone shell of a preferred embodiment of the present invention can be the shell of products such as mobile phone, PDA, notebook computer, MP3, MP4, GPS navigator, bluetooth earphone, digital camera and sound box.

[0014] The material of the stone shell is iron shot stone. The main component of the iron pellets is quartz (SiO 2 ), clay minerals and iron-calcium aggregates. In addition, iron shot stone also contains a small amount of impurities such as carbide, nickel oxide and lead oxide. In the iron shot stone, the mass percentage of quartz is 51-62%, the mass percentage of clay ore is 27-34%, the mass percentage of iron-containing calcium aggregate is 8-10%, and the impurities The mass percentage content is 3~5%. The clay minerals are kaolinite, montmorillonite, calcite, mica and illite. The clay ore contains Zn and Al 2 o 3 , CaO, MgO, Ba 2 o 3 , SiO 2 、TiO 2 and other oxides. The iron-containing calcium polymer contains Fe 2 o 3 , Fe 4 o 3 , CaCO ...

Abstract

A device housing providing a sensation of touch similar to that of jade is made of a material including quartz, clay mineral and a polymer composition containing calcium-magnesium. The clay mineral includes elemental Zn, aluminum oxide, calcium oxide, magnesium oxide, barium oxide, silicon oxide, and titanium oxide. The polymer composition containing calcium-magnesium comprises iron (III) oxide, iron (II, III) oxide, calcium carbonate, and calcium silicate. A method for manufacturing the device housing is also provided.

Description

technical field [0001] The invention relates to a stone casing and a manufacturing method thereof. Background technique [0002] The existing housings of electronic products are mainly made of metal, plastic and glass. However, because the metal shell is easily corroded by corrosive media, the decorative film layer on the surface of the metal shell will fall off, seriously affecting its appearance; the anti-aging performance of the plastic substrate is poor; and the glass shell is fragile and difficult to form complex three-dimensional structure. In addition, none of the shells made of the above three materials has a warm and delicate feel like jade. Contents of the invention [0003] In view of this, a stone shell with good aging resistance, corrosion resistance and hardness is provided. [0004] In addition, a method for manufacturing the above-mentioned stone casing is also provided. [0005] A stone shell, the material of the stone shell is iron shot stone, the mai...
