مطالعه خواص فیزیکی، مکانیکی و اشتعال پذیری آلیاژ ABS/PVC

نوع مقاله: مقاله پژوهشی

چکیده

در این پژوهش آلیاژهایی از دو نوع ABS و سه نوع کامپاند PVC به روش اختلاط مذاب تهیه و تأثیر نوع و ترکیب درصد اجزاء بر خواص فیزیکی و مکانیکی و اشتعال پذیری آنها مورد مطالعه قرار گرفت. مطالعات نشان داد که هر دو نوع ABS استفاده شده در این تحقیق، تأثیر مشابهی بر روند تغییرات خواص آلیاژها داشته ولی بهبود خواص فیزیکی و مکانیکی و همچنین کاهش اشتعال پذیری ABS به شدت تابع ترکیب درصد اجزاء و نوع PVC است. در اثر آلیاژ سازی ABS با PVC‌ نرم، مقاومت ضربه‌ای و شاخص مذاب (MFI)، نسبت به ABS به طور چشمگیری افزایش پیدا کرده ولی خواصی نظیر مقاومت کششی، مقاومت خمشی و سختی کاهش می‌یابد. رفتار این دسته از آلیاژها در برابر شعله تقریباً مشابه رفتار ABS‌ است. با اضافه کردن PVC ‌سخت به ABS‌، آلیاژهای به‌دست آمده، مقاومت قابل توجهی در برابر شعله پیدا کرده و در برخی خواص مکانیکی نظیر مقاومت کششی، مقاومت خمشی و سختی افزایش جزئی مشاهده می‌شود ولی مقاومت ضربه‌ای و MFI آلیاژها کاهش می‌یابد.

Study on Physical, Mechanical and Flammability of ABS/PVC Blends

چکیده [English]

In this research blends of two samples of Acrylonitrile-Butadiene-Styrene (ABS) with three samples of                                 Poly(vinyl chloride) (PVC) were prepared via melt processing and their physical, mechanical and fire properties were investigated. It was found that properties of blends were significantly depends on blend composition and PVC compound types, but the properties of blends containing different types of ABS similar results were seen. On blending of ABS with soft PVC compound, impact strength and melt flow index (MFI) of ABS were increased, however, tensile and flexural strength were decreased. In contrast, blending of ABS with rigid PVC improved its fire retardancy and some mechanical properties but decreased its MFI and impact strength.
