Description
Technical field
The present invention relates to Cellphone Accessories technical field, the manufacture method of a kind of plastic handset shell.
Background technology
Phone housing is mainly made up of metal or plastics.Metallic mobile phone shell has an advantage that texture is good, intensity is high, but it exists that cost is high, be difficult to processing, have signal problem, not easy coloring and complex process and the problem such as production efficiency is low, therefore it is commercially difficult to occupy advantage.And plastic handset shell cheap, be prone to processing, coloring easily, insulation, little on the impact of signal, and its forming method mainly injection and compacting etc., production efficiency is high, can be mass-produced, thus occupation rate commercially is of a relatively high.But, the intensity of existing plastic handset shell is low, shielding property is poor.
Summary of the invention
It is an object of the invention to provide the manufacture method of a kind of plastic handset shell, this method can solve the problem that existing cabinet intensity is low and shielding property is poor.
In order to solve the problems referred to above, the technical solution used in the present invention is: the manufacture method of this plastic handset shell comprises the following steps:

B, first by uniform to nanometer silicon B-carbide, nikel powder and polyaniline liquid mixing, more finish mix grain after batch mixing is dried；
C, preheating batch mixer, add step B gained material grain and remaining raw material mix homogeneously, joined by mixed material in extruder, through melt extruding pelletize；
D, granulation material is added after drying injection machine, after injection machine heating pressurize, fused materials is pushed in mould, after molding cooling, open mould and take out phone housing.
In the technical scheme of the manufacture method of above-mentioned plastic handset shell, more specifically technical scheme is it may also is that spray teflon coatings on the shell of step D gained, dries.
Further, Merlon 70 parts, acrylonitrile-butadiene-styrene copolymer 30 parts, Methacrylate-butadiene-styrene 5 parts, styrene-maleic anhydride copolymer 8 parts, fire retardant 8 parts, nanometer silicon B-carbide 25 parts, nikel powder 8 parts, polyaniline liquid 8 parts.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that prepared plastic handset outer cover intensity is high, and the most easy to crack, shielding property is good, and has preferably waterproof effect.
