ニレンエーテル系樹脂組成物に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention provides a polyphenylene ether resin composition that has excellent moldability and weather resistance, exhibits good surface gloss, and has excellent secondary processability such as paintability. relating to things.
ポリフェニレンエーテル樹脂(以下rPPB樹脂」と略
称する)は、耐熱性に優れ、機械的性質、電気的性質、

実用化されている。このように%PPB樹脂は耐熱性が
高いことが一つの大きな特徴であるが、反面、溶融粘度
が高いので成形加工性が悪く、さらに高温下において熱
酸化されやすいので、高温における成形加工によって本
来有する優れた性能が損われることが多い。Polyphenylene ether resin (rPPB resin) has excellent heat resistance, mechanical properties, electrical properties,
Since it has various other excellent properties, it has been put to practical use as an engineering plastic for various purposes by taking advantage of its properties. One of the major characteristics of %PPB resin is that it has high heat resistance, but on the other hand, it has poor moldability due to its high melt viscosity, and it is also prone to thermal oxidation at high temperatures, so it cannot be processed by molding at high temperatures. The excellent performance it possesses is often compromised.

の、PPB樹脂本来の特徴である耐熱性の低下、具体的
には熱変形温度の低下は避は難いのが実情である。Therefore, in order to improve the moldability of PPE resin, for example, US Patent No. 3,385,455 discloses that PPE resin
It is disclosed that polystyrene is blended with IB resin, and it is taught that by using rubber-modified polystyrene as the polystyrene, moldability and impact resistance are improved. However, although these resin compositions have improved moldability and impact resistance, they are not satisfactory in terms of surface gloss, weather resistance, secondary processability, and the like. Furthermore, as another method of improving moldability, a method of adding a plasticizer or a lubricant has also been proposed. but,
In either method, although moldability is improved, the reality is that it is difficult to avoid a decrease in heat resistance, specifically a decrease in heat distortion temperature, which is an inherent characteristic of PPB resin.
耐候性や表面光沢を改良するために、一般的には紫外線
吸収剤やシリコンオイル等を添加すればよいとされてい
るが、その効果は十分ではなく、また、表面光沢の改良
法として、ゴム変性ポリスチレン中のゴム粒径な小さく
することも提案されているが、この方法でも表面光沢の
改良はまだ不十分である。In order to improve weather resistance and surface gloss, it is generally considered that adding ultraviolet absorbers, silicone oil, etc. is sufficient, but the effect is not sufficient, and as a method for improving surface gloss, rubber It has also been proposed to reduce the rubber particle size in modified polystyrene, but even with this method the improvement in surface gloss is still insufficient.
さらに、無機充填剤や無機強化剤を配合したPPM樹脂
組成物では、表面光沢のみならず、塗装等の二次加工性
が悪いという間嘔点がある。Furthermore, PPM resin compositions containing inorganic fillers and inorganic reinforcing agents have drawbacks such as poor surface gloss and poor secondary processability such as painting.
