The invention discloses a surface decoration processing method of an electronic equipment housing, which comprises the following steps of nickel-tin alloy plating: a nickel-tin alloy layer is plated on an insulating substrate film, titanium oxide layer plating: a titanium oxide layer is plated on the nickel-tin alloy layer, voltage bombardment: the titanium oxide layer is bombarded via voltage, and ink printing: an ink layer is printed in a set area of the voltage bombarded titanium oxide layer. In some embodiments, the insulating substrate film is not easy to crack; the ink layer can be stably attached to the titanium oxide layer, so that a complete NCVM (non-conductive vacuum metallization) layer can be formed; and a stable and better gradient effect can be achieved. In certain embodiments, the side height of the manufactured electronic equipment housing can reach 9mm with a better gradient effect, and the surface hardness can reach 3-4H.

Embodiments of the present invention provide a method for preparing a casing, a casing, and an electronic device. The method for preparing the casing includes the following steps: forming a UV-curable adhesive layer on one surface of a substrate; UV-curable adhesive layer; a coating layer is formed on the UV-curable adhesive layer with pigments. The casing preparation method of the embodiment of the present invention can solve the problem of relatively large pattern noise on the surface of the casing.

The invention discloses a decorative body structure capable of realizing the gradual change of color, which comprises a front decorative body, a rear decorative body and a housing body; the rear decorative body is accommodated in a notch of the front decorative body, a reflecting surface which is manufactured by adopting a reflecting material is arranged on the front wall surface of the rear decorative body, a gap which is gradually increased from top to bottom is arranged between the front wall surface of the rear decorative body and the rear wall surface of the front wall of the front decorative body, the rear wall surface of the front wall of the front decorative body is shaped like an arc which is concave inwards, the thickness of the front wall of the front decorative body is gradually contracted from the top to the bottom, and the front wall surface of the rear decorative body is gradually inclined backwards from the top to the bottom and forms an included angle of about 70 degrees with the horizontal plane. The structure can lead a person to obtain the effect of the gradual change of the color of the front decorative body on the impression effect, that is the color is gradually changed from dark color to light color or gradually changed from dark to blue from the top to the bottom, and the decorative body structure has the characteristics of low manufacturing cost, easy realization and good gradual change effect; simultaneously, the structure can effectively improve the competitiveness of an electronic product, and be applicable to flat-panel televisions or other electronic products.

A laminated and molded body obtained by coextruding and molding at least two kinds of resin materials is preferable as a blow-molding aimed preform, a direct-blow molded bottle, a tube, or a blow molded tube, and has at least one layer constituted of a colored layer having a thickness continuously or intermittently varied in a direction parallel to the extruding direction of the at least one layer and / or in another direction intersecting the extruding direction, thereby enhancing the gradation effect.

The application provides a gradient anti-glare cover plate and a making method thereof as well as electronic equipment. The making method comprises the following steps: providing a substrate; making graded-density grooves in at least one surface of the substrate, wherein the distance between the every two adjacent grooves is less than 5 microns; demoulding; making uneven anti-glare structures on the surfaces of the grooves. The graded-density grooves are firstly formed before anti-glare production, and the distance between the every two adjacent grooves is less than 5 microns, so that the natural gradual change of light can be realized, a gradual change effect is achieved, and the appearance of the gradient anti-glare cover plate is enabled to be more attractive; therefore, the gradient anti-glare cover plate is more greatly different from cover plates of other electronic products, and a homogenization phenomenon is further avoided. Furthermore, the anti-glare effect of the gradient anti-glare cover plate is realized mainly by means of irregular rugged small salient points directly formed in the grooves, and a diffuse reflection function is realized; the gradient and anti-glare effect is realized only by combining the two processes, so that the making technology is simple.

The invention discloses a process for preparing self-generated radially gradient composite materials by an in-situ crystallization method, which belongs to the field of composite material preparation. Specifically: after remelting the self-generated composite material, the remelting temperature is 50-150°C above the liquidus line, pouring it into a SiC casting mold; generating an induced high-frequency magnetic field through a high-frequency power supply and a cylindrical axisymmetric induction coil, and then With the reduction of the power supply of the induced high-frequency magnetic field by 7Kw~2Kw, the preheating temperature of the casting mold is increased linearly by 30℃~300℃; the temperature measuring device of the single-channel SiC casting mold is used to monitor the temperature of the self-generated composite material. When the temperature of the self-generated composite material drops close to the eutectic temperature of the material, the high-frequency magnetic field is turned on, and the action time is 4s-32s. When the temperature of the self-generated composite material rises close to the liquidus temperature, the effect of the high-frequency magnetic field is terminated; finally, the self-generated composite material Solidification molding in SiC casting mold. The invention significantly increases the effective action time of the high-frequency magnetic field and improves the yield of materials.
