Since a normal resin housing has no conductivity, it does not have an electromagnetic wave shielding ability, which results in promoting electromagnetic wave interference. In addition, since most of electronic devices have a live part, a casing used for the live part must also have flame retardancy, and additionally, impact resistance and heat resistance are required.

As a method of shielding electromagnetic waves using a resin housing,
There are a method of blending a conductive filler with the resin, a method of conductive coating, metal spraying, vacuum deposition, sputtering, and a conductive surface treatment such as metal plating. Among these methods, the electroless plating method is the most excellent in terms of high shielding effect and certainty. On the other hand, the only resin that can be easily electroless plated is an acrylonitrile-butadiene-styrene terpolymer (hereinafter abbreviated as ABS) resin.
For other resins without exception, it is necessary to mix the inorganic filler in the resin body, pre-etch in the plating process, adjust the surface by post-etching, neutralization, etc., and improve the adhesion strength by annealing, etc. It is not preferable because it causes deterioration of physical properties and high cost. In addition, the flame retardant of ABS (hereinafter abbreviated as FRABS) has problems such as low heat distortion temperature, halogen compound as a flame retardant, corrosion of molding die and deterioration of catalyst in plating process.

無電解メッキができる難燃樹脂組成物を得るべく鋭意検
討した結果、次に述べる知見を得た。
The present inventor is mainly composed of PPE resin and ABS resin,
As a result of intensive studies to obtain a flame-retardant resin composition capable of easily performing electroless plating while maintaining sufficient flame retardancy, impact resistance and heat resistance, the following findings were obtained.

1)難燃剤として芳香族燐酸エステルを多量に使用した

1) When a large amount of an aromatic phosphate ester is used as a flame retardant, the flame retardancy is satisfactory, but the heat distortion temperature of the resin composition decreases, and in order to maintain this, the amount of the PPE resin must be increased. . However, when the amounts of the aromatic phosphate and the PPE resin are increased, the deposition property and adhesion of the electroless plating are reduced.

2) When red phosphorus is used as the flame retardant, the heat distortion temperature of the resin composition does not decrease. Therefore, when red phosphorus is used,
Not only flame retardancy is obtained, but also aromatic phosphates and
Since the amount of PPE resin can be reduced, excellent electroless plating properties can be obtained. When a large amount of red phosphorus is used, the impact resistance of the resin composition decreases. In order to obtain the required flame retardancy without impairing the impact resistance, it is necessary to use red phosphorus and an aromatic phosphate together.

3)ABS樹脂とPPE樹脂の相溶性を改良した場合、無電解
メッキは均一な厚さで密着性も良いものが得られる。
3) When the compatibility between the ABS resin and the PPE resin is improved, the electroless plating can have a uniform thickness and good adhesion.

4)ABS樹脂の量が多すぎると、エッチング工程での成
形品表面が、エッチング過剰になるため無電解メッキ品

4) If the amount of the ABS resin is too large, the surface of the molded product in the etching step becomes excessively etched, so that the surface condition of the electroless plated product deteriorates.

5)PPE樹脂/ABS樹脂組成物中のアクリロニトリル量
は、成形品の剥離性だけでなく、無電解メッキの析出量
や密着性にも大きな影響を持つ。
5) The amount of acrylonitrile in the PPE resin / ABS resin composition has a great influence not only on the releasability of the molded product, but also on the deposition amount and adhesion of electroless plating.

When a rubber-like elastic body containing no conjugated double bond, such as a hydrogenated product of an ethylene-propylene copolymer or a styrene-butadiene block copolymer, is used, etching is difficult, the anchor effect is reduced, and plating adheres. It is better to avoid it because it deteriorates the sex.

In the present invention, the graft ratio of the graft component to the rubber-like elastic material of the graft rubber phase (α) in the component (B) is desirably 40 to 300%, preferably 40 to 200%. When the graft ratio is 40% or less, the compatibility between the components (A) and (C) and the component (B) is insufficient, so that the molded product is likely to be peeled off and the dispersibility of the component (B) is deteriorated. Therefore, unevenness is caused in the thickness of the plating, and the adhesion is reduced, which is not preferable. If a graft ratio of more than 300% is to be obtained, the polymerization time must be significantly increased, which is not preferable from an economic viewpoint.

On the other hand, when the content exceeds 30% by weight and 9% by weight, respectively, not only the molded product is easily peeled off, but also it becomes difficult to be etched in the electroless plating step.
