Embodiment 1

[0187] (flexural modulus of filler-reinforced plastics)

[0188] Using an injection molding machine, material F was molded into a test piece having a thickness of 12.5 mm×127 mm×4 mm. The bending modulus was measured about the said test piece. The results are shown in Table 3.

[0189] (Flexural modulus of plated test piece)

[0190] Using an injection molding machine, the material F was molded into a test piece having a thickness of 12.5 mm×127 mm×1 mm, and a plated layer was formed with the structure shown in Table 2 and the target total thickness a to obtain a plated test piece.

[0191] The bending modulus was measured about the said plating processing test piece. The results are shown in Table 3.

[0192] (plated plastic case)

[0193] Using an injection molding machine, material F was molded into a plastic case main body (internal case test piece for mobile equipment) with a thickness of 80 mm x 125 mm x 1.5 mm, and a plating layer was formed with the composition sh...

Embodiment 2～25

[0194] [Examples 2-25, Comparative Examples 1-5]

[0195]The material F was changed to the materials shown in Tables 3 and 4, and the composition of the plating layer and the target total thickness a were changed to the structures and target total thicknesses shown in Tables 3 and 4, and the test was obtained in the same manner as in Example 1. Sheets, plated test pieces and plated plastic casings. The results are shown in Tables 3 and 4.

Abstract

According to the present invention, there is provided a plastic casing and a component for electrical products in which a component base material containing a thermoplastic resin is adhered to the above-mentioned plastic casing, and the plastic casing can achieve a complicated shape and a thinner wall due to resinization And light weight, even if the wall is thinner and lighter, it has the same rigidity and durability under high temperature conditions as the magnesium metal casing, and by suppressing the warpage and size that are accompanied by thinner wall and lighter weight The reduction of precision can ensure the safety of products. The present invention relates to a plated plastic case comprising: a plastic case main body formed by molding a filler-reinforced plastic having a flexural modulus of ISO 178:2001 of 4,000 to 22,000 MPa; A plating layer with a thickness of 5 to 50 μm is formed on at least a part of the surface.

Description

technical field [0001] The present invention relates to a plated plastic chassis used as an inner casing of electrical products and the like. [0002] This application claims priority based on Japanese Patent Application No. 2012-057957 for which it applied in Japan on March 14, 2012, and uses the content here. Background technique [0003] Cases of weak current products such as mobile phones and notebook computers require high rigidity along with thinning of the product. In this application, metal cases formed by die casting or melt molding using magnesium have been frequently used so far. Recently, plastic cases such as polycarbonate resin, polycarbonate / ABS resin, etc. have been plated and thickened with metal to increase rigidity as a substitute for metal cases. [0004] In addition, high rigidity is also required for an internal casing provided inside an electrical product, and therefore a metal casing such as magnesium is used. Recently, plastic casings have been st...
