Abstract
Description
本発明は、樹脂組成物、成形体、電子部品、及び電子機器に関する。 The present invention relates to resin compositions, molded articles, electronic components, and electronic devices.
一般に有機物である高分子樹脂材料は火災時に燃焼するので、難燃剤を添加した難燃性樹脂が、自動車材料、電気電子機器材料、住宅材料、その他の加工分野における部品製造用材料等に幅広く使用されている。このような樹脂材料について、難燃性だけでなく機械的強度も良好である事が求められており、とりわけ衝撃強度に耐える必要がある。これを実現するためには、良好な外観を射出成形で容易に得ることができるために市場で普及しているポリカーボネート（ＰＣ）樹脂に、ＡＢＳ樹脂やポリスチレン（ＰＳ）樹脂を配合した樹脂組成物が知られている。特に、コストダウンを目的とした場合、ＰＣ／ＰＳアロイを用いることが既に知られている。 Since polymer resin materials, which are generally organic substances, burn in the event of a fire, flame retardant resins containing flame retardants are widely used in automobile materials, electrical and electronic equipment materials, housing materials, and materials for manufacturing parts in other processing fields. Has been done. Such a resin material is required to have good mechanical strength as well as flame retardancy, and in particular, it is necessary to withstand impact strength. In order to realize this, a resin composition obtained by blending ABS resin or polystyrene (PS) resin with polycarbonate (PC) resin, which is widely used in the market because a good appearance can be easily obtained by injection molding. It has been known. In particular, it is already known to use a PC / PS alloy for the purpose of cost reduction.
特許文献１には、難燃性と剛性、及び耐衝撃性に特に優れた樹脂組成物の提供する目的で、ポリカーボネート（ＰＣ）樹脂とその他樹脂と、リン含有化合物とを含有する樹脂組成物が開示されている。この樹脂組成物は前記リン含有化合物としてホスファゼン誘導体、及びリン酸エステルを含有しており、難燃性と剛性、及び耐衝撃性に優れた樹脂組成物となっている。特許文献１には、樹脂１００質量部に対してＰＣ樹脂８０質量部、ＡＢＳ樹脂１６重量部、ＰＳ樹脂４質量部の構成が開示されている。 Patent Document 1 describes a resin composition containing a polycarbonate (PC) resin, another resin, and a phosphorus-containing compound for the purpose of providing a resin composition having particularly excellent flame retardancy, rigidity, and impact resistance. It is disclosed.

Preferably, it is 1.0 part by mass or more and 3.0 part by mass or less with respect to 100 parts by mass of the total resin.
If the content is less than 0.1 parts by mass, the content is too small to achieve the object of the present invention. If it is contained in an amount exceeding 4.0 parts by mass, it tends to aggregate in the resin composition during kneading, which is not preferable. When the content is 4.0 parts by mass or less, it becomes difficult to aggregate in the resin composition, and it becomes easy to achieve the object of the present invention.
（ホスファゼン系化合物以外のリン系化合物）

Knead while appropriately adjusting conditions such as speed, kneading temperature, and kneading time.
例えば、上記各成分を、タンブラー、ヘンシェルミキサー等を用いて、予め混合した後、バンバリーミキサー、ロール、ブラベンダー、単軸混練押出機、二軸混練押出機、ニーダー等の混練機で溶融混練してもよい。また、例えば、各成分を予め混合せずに、これらの成分をフィーダーを用いて押出機に投入し、溶融混練してもよい。更に、例えば、一部の成分のみを予め混合し、その後、溶融混練することによって得られる樹脂組成物をマスターバッチとし、このマスターバッチと再度残りの成分とを溶融混練してもよい。 For example, each of the above components is mixed in advance using a tumbler, a Henschel mixer, or the like, and then melt-kneaded by a kneader such as a Banbury mixer, a roll, a lavender, a single-screw kneading extruder, a twin-screw kneading extruder, or a kneader. You may. Further, for example, these components may be put into an extruder using a feeder and melt-kneaded without mixing the components in advance. Further, for example, the resin composition obtained by premixing only a part of the components and then melt-kneading may be used as a masterbatch, and the masterbatch and the remaining components may be melt-kneaded again.
ここで、この工程では、特に限定されることなく、任意選択された成分を予め溶融混合させた後に、二軸混練押出機に添加することも好ましい。リン酸エステルが室温で液体の場合、ホスファゼン系化合物をこの成分に室温で溶解させることが可能である。また、リン酸エステルが室温で固体（例えば、粉末）の場合、これらの成分を乳鉢で混ぜた後、混合物を９０℃以上に加熱して溶融させ、この溶融状態の混合物を二軸混練押出機に添加することが可能である。 Here, in this step, without particular limitation, it is also preferable that the arbitrarily selected components are melt-mixed in advance and then added to the twin-screw kneading extruder. When the phosphate ester is liquid at room temperature, the phosphazene compound can be dissolved in this component at room temperature. When the phosphoric acid ester is solid (for example, powder) at room temperature, these components are mixed in a dairy pot, and then the mixture is heated to 90 ° C. or higher to melt the mixture, and the mixed mixture in the molten state is melted by a twin-screw kneading extruder. Can be added to.
なお、上記リン酸エステルとホスファゼン系化合物の予混合は、溶融混練工程の例示であり、リン系化合物の分散性を高める観点から、好ましい実施形態となるが、本発明の樹脂組成物の製造方法において必須となるものではない。また、上記乳鉢を用いた混合は、混合方法の例示であり、本発明の樹脂組成物の製造方法における混合方法は、これに限定されるものではなく、いかなる方法としてもよい。 The premixing of the phosphoric acid ester and the phosphazene-based compound is an example of the melt-kneading step, and is a preferred embodiment from the viewpoint of enhancing the dispersibility of the phosphorus-based compound. It is not essential in. Further, the mixing using the mortar is an example of the mixing method, and the mixing method in the method for producing the resin composition of the present invention is not limited to this, and may be any method.
特に、混練温度は、ＰＣ樹脂の溶融温度（Ｔｍ）を基に決められる。Ｔｍの測定については、ガラス転移点（Ｔｇ）と同様にＤＳＣ、ＴＭＡ、ＤＴＡ、温度を変えられる粘弾性装置などどのような測定値を用いても良いが、これらの装置を用いて測定されたＴｍ温度付近で混練すれば本発明の樹脂組成物が容易に得られる。 In particular, the kneading temperature is determined based on the melting temperature (Tm) of the PC resin. For the measurement of Tm, any measured value such as DSC, TMA, DTA, and a viscoelastic device whose temperature can be changed may be used as in the case of the glass transition point (Tg), but the measurement was performed using these devices. The resin composition of the present invention can be easily obtained by kneading at a temperature near Tm.
また、このＴｍ温度未満では、剪断流動が効果的に働き、ホスファゼン系化合物のドメイン形成を阻害するので好ましい。特に混練温度をＴｍ未満からＴｇ＋２０℃の温度領域で本発明の好適な結果を得ることが可能である。 Further, below this Tm temperature, the shear flow works effectively and inhibits the domain formation of the phosphazene compound, which is preferable. In particular, it is possible to obtain the preferable results of the present invention in the temperature range of the kneading temperature of less than Tm to Tg + 20 ° C.
ＴｍやＴｇについては測定方法で変わることが知られている。本発明では、ＤＳＣで計測されたＴｍやＴｇの値を用いるのが好ましい。 It is known that Tm and Tg vary depending on the measurement method. In the present invention, it is preferable to use the values of Tm and Tg measured by DSC.
