近年、スマートフォンを含む携帯電話の開発に伴い、携帯電話の内部にアンテナを製造する方法が種々検討されている。特に、携帯電話に3次元設計ができるアンテナを製造する方法が求められている。このような3次元アンテナを形成する技術の1つとして、レーザーダイレクトストラクチャリング(以下、「LDS」ということがある)技術が注目されている。LDS技術は、例えば、LDS添加剤を含む樹脂成形品の表面にレーザーを照射し、レーザーを照射した部分のみを活性化させ、該活性化させた部分に金属を適用することによってメッキ層を形成する技術である。この技術の特徴は、接着剤などを使わずに、樹脂基材表面に直接にアンテナ等の金属構造体を製造できる点にある。かかるLDS技術は、例えば、特許文献1~3等に開示されている。
In recent years, with the development of mobile phones including smartphones, various methods for manufacturing antennas inside mobile phones have been studied. In particular, there is a need for a method of manufacturing an antenna that can be three-dimensionally designed for a mobile phone. As one of the techniques for forming such a three-dimensional antenna, a laser direct structuring (hereinafter, also referred to as “LDS”) technique has attracted attention. LDS technology, for example, irradiates the surface of a resin molded product containing an LDS additive with a laser, activates only the portion irradiated with the laser, and forms a plating layer by applying metal to the activated portion. Technology. A feature of this technique is that a metal structure such as an antenna can be manufactured directly on the surface of the resin base material without using an adhesive or the like. Such LDS technology is disclosed in, for example, Patent Documents 1 to 3.
ここで、機械的特性を向上させるためにガラス繊維を配合しようとすると、難燃性が劣る傾向にある。また、本発明者が検討したところ、LDS添加剤の種類によっても、難燃性に影響が出ることが分かった。本発明はかかる従来技術の問題点を解決することを目的としたものであって、メッキ性を維持しつつ、曲げ弾性率、曲げ強度、シャルピー衝撃強さや荷重たわみ温度などの各種機械的特性および難燃性に優れた樹脂組成物を提供することを目的とする。
Here, if glass fiber is added to improve mechanical properties, the flame retardancy tends to be inferior. In addition, as a result of examination by the present inventors, it was found that the flame retardancy is also affected by the type of LDS additive. The present invention aims to solve the problems of the prior art, and maintains various plating properties while maintaining various plating properties such as bending elastic modulus, bending strength, Charpy impact strength and deflection temperature under load, and the like. It aims at providing the resin composition excellent in the flame retardance.

The number average particle diameter of the polyorganosiloxane is preferably 10 nm or more, more preferably 50 nm to 5 μm, and even more preferably 100 nm to 3 μm.

Examples of the alkyl (meth) acrylate include alkyl acrylates such as methyl acrylate, ethyl acrylate, n-propyl acrylate, n-butyl acrylate, and 2-ethylhexyl acrylate, and methyl methacrylate, hexyl methacrylate, 2-ethylhexyl methacrylate, n- Examples thereof include alkyl methacrylates such as lauryl methacrylate.

多官能性単量体を使用する場合の含有量には特に制限はないが、ポリアルキル(メタ)アクリレート100質量%中の0.1~2質量%であることが好ましく、0.3~1質量%であることがより好ましい。多官能性単量体の含有量を0.1質量%以上とすることにより、複合ゴムのモルフォロジーの変化による衝撃強度の低下を抑制できる傾向にあり、また、多官能性単量体の含有量を2質量%以下とすることにより、衝撃強度がより向上する傾向にある。
The content in the case of using a polyfunctional monomer is not particularly limited, but it is preferably 0.1 to 2% by mass in 100% by mass of polyalkyl (meth) acrylate, and 0.3 to 1 More preferably, it is mass%. By setting the content of the polyfunctional monomer to 0.1% by mass or more, there is a tendency to suppress a decrease in impact strength due to a change in the morphology of the composite rubber, and the content of the polyfunctional monomer. When the content is 2% by mass or less, the impact strength tends to be further improved.

各樹脂組成物の難燃性の評価は、上述の方法で得られたUL試験用試験片を温度23℃、湿度50%の恒温室の中で48時間調湿し、米国アンダーライターズ・ラボラトリーズ(UL)が定めているUL94試験(機器の部品用プラスチック材料の燃焼試験)に準拠して行なった。UL94Vとは、鉛直に保持した所定の大きさの試験片にバーナーの炎を10秒間接炎した後の残炎時間やドリップ性から難燃性を評価する方法であり、V-0、V-1及びV-2の難燃性を有するためには、以下の表に示す基準を満たすことが必要となる。
The flame retardancy of each resin composition was evaluated by conditioning the test piece for UL test obtained by the above-mentioned method for 48 hours in a temperature-controlled room at a temperature of 23 ° C. and a humidity of 50%, and US Underwriters Laboratories. The test was conducted in accordance with the UL94 test (combustion test of plastic materials for equipment parts) defined by (UL). UL94V is a method for evaluating flame retardancy from the afterflame time and drip properties after indirect flame of a burner for 10 seconds on a test piece of a predetermined size held vertically, V-0, V- In order to have flame retardancy of 1 and V-2, it is necessary to satisfy the criteria shown in the following table.
ここで残炎時間とは、着火源を遠ざけた後の、試験片の有炎燃焼を続ける時間の長さである。また、ドリップによる綿着火とは、試験片の下端から約300mm下にある標識用の綿が、試験片からの滴下(ドリップ)物によって着火されるかどうかによって決定される。さらに、5試料のうち、1つでも上記基準を満たさないものがある場合、V-2を満足しないとしてNR(not rated)と評価した。
Here, the afterflame time is the length of time for which the test piece continues to burn with flame after the ignition source is moved away. The cotton ignition by the drip is determined by whether or not the labeling cotton, which is about 300 mm below the lower end of the test piece, is ignited by a drip from the test piece. Furthermore, if any one of the five samples did not satisfy the above criteria, it was evaluated as NR (not rated) as not satisfying V-2.
