Abstract

Acidic pumice (AP) and basic pumice (BP) were
compatibilised with the polymer matrix by using silane coupling agents before
their addition into polypropylene (PP). In addition, composites with maleic
anhydride grafted polypropylene (Ma-g-PP) were prepared. Composites were
prepared by melt-blending method using lab-scale twin screw extruder which is
the most suitable method for the large scale production. PP composites that
obtained as chip form from the mixer were shaped with injection molding.
Additionally to the mechanical properties of prepared composites, water
absorption test of the composites were performed in order to investigate their
outdoor usage conditions.  Tensile test,
dynamic mechanical analysis (DMA) and melt flow index tests were applied to composites,
respectively. Furthermore, scanning electron microscopy (SEM) micrographs were
examined for observation of the dispersion of pumice particles into
polypropylene matrix. Improvements in mechanical properties of composites were
obtained by using silane-modified acidic pumice, basic pumice and MA-g-PP.
According to SEM micrographs, composites which contain silanized pumice and
MA-g-PP exhibit better dispersion of pumice particles into PP matrix due to
compatibilazition of particles with polymer surfaces. There were no remarkable
changes observed for the melt flow values of especially acidic pumice
containing composites as compared with PP. 
This results support the conclusion that the addition of pumice caused
no obvious problem for the processibily of polypropylene in large scale
applications.

Abstract

 Asidik pomza (AP) ve bazik pomza
(BP) polipropilene (PP) eklenmeden önce silan bağlayıcı kullanılarak polimer
matris ile uyumlu hale getirilmiştir. Bunun yanı sıra, maleik anhidrit
aşılanmış PP (MA-g-PP) ile kompozitler hazırlanmıştır. Kompozitler, büyük
ölçekli üretime en uygun yöntem olan eriyik karıştırma metodu ile laboratuvar
ölçekli çift vidalı ekstruder kullanılarak üretilmiştir. Karıştırıcıdan çip
formunda elde edilen PP kompozitler, enjeksiyonlu kalıplama tekniği ile
şekillendirilmiştir. Hazırlanan kompozit numunelerinin mekanik dayanımları
başta olmak üzere su emme testi ile dış hava şartlarında kullanımları
incelenmiştir. Kompozitlere sırasıyla çekme testi, dinamik mekanik analiz (DMA)
ve eriyik akış indisi testleri uygulanmıştır. Ayrıca pomza parçacıklarının
polipropilen matris içinde dağılımını gözlemlemek için tarayıcı elektron
mikroskobu (SEM) mikrografikleri incelenmiştir. Silan ile modifiye edilmiş
asidik pomza, bazik pomza ve MA-g-PP ile hazırlanan kompozitlerin mekanik
özelliklerinde iyileşmeler saptanmıştır. SEM mikrografikleri incelendiğinde;
silanlanmış pomza içeren ve MA-g-PP matrisli kompozitlerde pomza parçacıklarının,
polimer yüzeyleri ile uyumlu hale geldiğinden PP matris içerisinde iyi dağılım
gösterdigi belirlenmiştir. Özellikle asidik pomza içeren kompozitlerin erime
akış değerlerinde, PP ile kıyaslandığında belirgin bir değişme olmamıştır. Bu
sonuç, büyük ölçekteki uygulamalarda pomzanın dolgu maddesi olarak eklenmesiyle
polipropilenin işlenmesinde önemli bir sorunla karşılaşılmayacağı çıkarımını
desteklemektedir.
