Odun plastik kompozit malzemelerin termal ve ısı iletkenliği özelikleri üzerine sepiolit mineralinin etkisi
Abstract
Bu çalışmada amaç, polipropilen esaslı odun plastik kompozit (OPK) malzeme üretiminde kullanılan sepiolit mineralinin termal özellikler ve ısı iletkenliği üzerine etkisinin araştırılması olacaktır. Çift vidalı ekstruder ile odun unu, polipropilen ve sepiolit minerali karışımından elde edilen peletler, öğütülmüş ve presleme işlemi yapılarak OPK levhalar üretilmiştir. Üretilen levhaların ısı iletkenliği özelliklerinin (ASTM C 1113-09) yanı sıra Termogravimetrik Analiz (TGA) ve Diferansiyel Taramalı Kalorimetri (DSC) gibi termal özellikleri belirlenmiştir. OPK malzemelerde yangın geciktirici olarak kullanılan sepiolit mineralinin eklenme miktarının artması ile termal ve ısı iletkenliği özelliklerinin geliştiği, kristalizasyon derecesinin ise azaldığı belirlenmiştir.

Effect of sepiolit mineral on thermal properties and thermal conductivity of wood plastic composite materials
Abstract
The aim of this study is to investigate the effect of sepiolite mineral used in the production of polypropylene based wood plastic composite (OPK) materials on thermal properties and thermal conductivity. The pellets obtained from the mixture of wood flour, polypropylene and sepiolite minerals with double-screw extruder were milled and pressed to produce OPK boards. Thermal properties such as Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) as well as the thermal conductivity properties of the produced boards (ASTM C 1113-09) have been determined. It has been determined that the addition of the sepiolite mineral used as fire retardant in OPK materials increases the thermal and thermal conductivity properties, while the crystallization degree decreases.
