Abstract
Description
本発明は、循環社会に貢献できる、高生産時にも衝撃強度、表面外観に優れる、回収ポリスチレン配合ポリフェニレンエーテル系樹脂組成物の製造方法に関するものである。 The present invention relates to a method for producing a recovered polystyrene-containing polyphenylene ether-based resin composition that can contribute to a recycling society and has excellent impact strength and surface appearance even during high production.
家電リサイクル法が施行され、家電OA分野におけるポリスチレンの回収も多く発生している。この回収家電品の筐体等を粉砕して粉砕ペレットが利用されるようになった。しかしながらこの粉砕ペレットを用いた組成物は、物性低下が大きく、成形品の強度、表面外観等が著しく低下する。家電リサイクル法によって回収される家電樹脂には、ハロゲンやアンチモン、電気配線、電子回路などに用いられた材料の粉砕品も混合されており、特に金属の混入は、回収粉砕ペレットを用いて製造された製品の強度、表面外観等を著しく低下させる。回収粉砕ペレットは設置環境により、長期に渡り太陽光などで経年劣化の可能性もあり、さらに再溶融による熱履歴により熱劣化の可能性も否定できない。溶融濾別時にできる限り低温で濾別し、熱安定剤を添加することで樹脂の劣化を防止することができる。ところで、特許文献1〜2には回収ポリスチレン配合ポリフェニレンエーテル系樹脂組成物が開示されているが、特許文献1では、主に発泡体についての製法記載であり、特許文献2には、粉砕品の形状、金属異物が押出機に与える影響の記載はあるが、樹脂材料に与える影響についての記載はない。
The Home Appliance Recycling Law has been enforced, and many polystyrene collections have occurred in the home appliance OA field. Crushed pellets have been used by crushing the housing of the collected household appliances. However, the composition using the pulverized pellets is greatly deteriorated in physical properties, and the strength, surface appearance and the like of the molded product are remarkably reduced. Home appliance resin recovered by the Home Appliance Recycling Law is mixed with pulverized products of materials used for halogen, antimony, electrical wiring, electronic circuits, etc. Especially metal contamination is produced using recovered pulverized pellets. The product strength and surface appearance are significantly reduced. Depending on the installation environment, the recovered pulverized pellets may deteriorate over time due to sunlight or the like, and the possibility of thermal deterioration due to heat history due to remelting cannot be denied. It is possible to prevent deterioration of the resin by filtering at a temperature as low as possible during melt filtration and adding a heat stabilizer. Incidentally,
本発明は、市場から回収されるポリスチレン系樹脂を用い、特に家電及びOA機器からの回収ポリスチレン樹脂を含有するポリフェニレンエーテル系樹脂組成物の改善された製造方法を提供することを目的とする。 An object of this invention is to provide the improved manufacturing method of the polyphenylene ether-type resin composition which uses the polystyrene-type resin collect | recovered from a market, and contains especially the collection | recovery polystyrene resin from a household appliance and OA apparatus.
