In this study; poppy stalks collected from Afyonkarahisar/Sinanpaşa district were added to the polypropylene produced with the trade name NAFILean-PF2 555 (20% hemp added PP) at a rate of 20%. MAPP, which was added as a compatibility agent, was added at 5-10 and 15% ratios, mixed in a twin screw extruder and produced as granules. The effect of the addition of maleic anhydride grafted polypropylene (MAPP) at different rates on its mechanical and morphological properties was investigated. The granules obtained in the extruder were dried and the test samples were molded in the injection machine in accordance with the standards. In order to determine the mechanical values of the obtained polymer composite, modulus of elasticity, tensile strength, breaking strength, elongation at break, impact strength and hardness tests were carried out. In addition, photographs were taken with scanning electron microscopy (SEM) to determine the distribution of hemp and poppy stems. As a result of the analysis, with the addition of poppy stalks and MAPP in 20% hemp added PP (NAFILean-PF2 555); It was determined how the modulus of elasticity, tensile strength, breaking strength, elongation at break, impact strength and hardness values changed. As a result of SEM examination, it was determined that hemp and poppy particles were homogeneously dispersed.

Ticari NAFILean Polipropilen/Haşhaş (Papaver Somniferum) Sapı Polimer Kompozitinin Mekanik ve Morfolojik Özelliklerine MAPP’nin Etkisi

Öz

Bu çalışmada; NAFILean-PF2 555 (%20 kenevir katkılı PP) ticari ismi ile üretilen polipropilene Afyonkarahisar/Sinanpaşa ilçesinden temin edilen haşhaş sapları %20 oranında katılmıştır. Uyumluluk maddesi olarak maleik anhidrit aşılı polipropilen (MAPP) %5-10 ve 15 oranlarında katılarak çift vidalı ekstruderde karıştırılmış ve granül halinde üretilmiştir. Mekanik ve morfolojik özelliklerine değişik oranlarda MAPP ilavesinin etkisi araştırılmıştır. Ekstrüzyon makinesinde elde edilen granüller kurutulmuş ve enjeksiyon makinesinde standartlara uygun şekilde test numuneleri basılmıştır. Elde edilen polimer kompozitinin mekanik değerlerinin belirlenmesi için elastiklik modülü, çekme mukavemeti, kopma mukavemeti, kopma uzaması, darbe mukavemeti ve sertlik testleri yapılmıştır. Ayrıca kenevir ve haşhaş saplarının dağılımlarını belirlemek için taramalı elektron mikroskobisi (SEM) ile fotoğrafları çekilmiştir. Analizler sonucunda %20 kenevir katkılı PP (NAFILean-PF2 555) içerisinde haşhaş ve MAPP ilavesiyle; elastiklik modülü, çekme mukavemeti, kopma mukavemeti, kopma uzaması, darbe mukavemeti ve sertlik değerlerinin nasıl değiştiği belirlenmiştir. SEM incelemesi sonucunda kenevir ve haşhaş partiküllerinin homojen dağıldığı tespit edilmiştir.
