Embodiment Construction

[0020] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 1 as shown, figure 1 It is a flow chart of the first embodiment of the method for preparing a TV casing of the present invention. The method for preparing a TV casing mentioned in this embodiment comprises the steps of:

[0022] Step S111, using PC as a carrier, adding the first color powder, stirring evenly, drying with hot air, and granulating to obtain the first color masterbatch;

[0023] Step S112, using PMMA as a carrier, adding a second color powder, stirring evenly, drying with hot air, and granulating to obtain a second color masterbatch;

[0024] This step adopts PC and PMMA as carrier, because PC and PMMA are not easy to dissolve, therefore, adopt the color powder of different colors to mix with PC and PMMA respectively, be helpful for making the plastic shell of wood grain effect, ...

Abstract

The invention discloses a preparation method of a television shell. The preparation method comprises the following steps of: adding first color powder by taking PC (Poly Carbonate) as a carrier, uniformly stirring, carrying out hot air drying, and pumping tablets to obtain first color masterbatch; adding second color powder by taking PMMA (Polymethyl Methacrylate) as a carrier, uniformly stirring, carrying out hot air drying, and pumping tablets to obtain second color masterbatch; mixing the first color masterbatch and the second color masterbatch by taking HIPS (High Impact Polystyrene) or ABS (Acrylonitrile Butadiene Styrene) natural color materials as main materials, uniformly stirring, and carrying out hot air drying to obtain an injection molding mixture; conveying the injection molding mixture to the hopper of an injection molding machine tool, melting through the injection molding machine tool to prepare molten gel, and filling the molten gel into the cavity of a mould; and cooling the molten gel inside the mould to manufacture the television shell, and separating the television shell from the mould. The method disclosed by the invention has the advantages of easiness and convenience for preparation, short manufacturing time consumption, high efficiency and low cost.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a method for preparing a television casing. Background technique [0002] At present, the TV casings on the market are mainly black, silver, white, transparent borders, decorative strips and other appearance colors. With the continuous replacement of consumer groups, aesthetic fatigue has appeared for common colors. It is expected that there will be a subversive A new look of traditional tones emerges, highlighting the individuality and fashion of modern people. The appearance of wood grain decoration in retro style has become the most trendy choice in the eyes of many consumers. However, the wood-grain-like hues that appear on existing handicrafts or artworks are usually achieved by methods such as film paper transfer, two-color injection molding, co-extrusion, spraying, etc. The cost is high and the efficiency is low. It is very difficult to realize on the size parts, and...
