POLİ(BÜTİL AKRİLAT-KO-METİL METAKRİLAT)/MONTMORİLLONİT SENTEZİ VE YOL ÇİZGİ BOYA BAĞLAYICISI OLARAK KULLANIMI

Bu çalışmada, su bazlı kaplama malzemelerinde bağlayıcı olarak kullanılan poli(bütil akrilat-ko-metil metakrilat) kopolimerinin emülsiyon polimerizasyonu ile sentezlenmesi amaçlanmıştır. Sentezlenen kopolimerin film özelliklerini geliştirmek amacıyla Na-montmorillonit kullanılarak nanokompozit elde edilmiştir. Diferansiyel taramalı kalorimetre (DSC) ile camsı geçiş sıcaklığı, termal gravimetrik analiz (TGA) ile ısıl kararlılık belirlenmiştir. Bu analizler kopolimerin ısıl özelliklerinin geliştiğini göstermiştir. Ayrıca gerçekleştirilen mekanik test ile mekanik dayanımın da arttığı görülmüştür. Elde edilen katkısız ve montmorillonit katkılı kopolimerlerin bağlayıcı olarak kullanıldığı su bazlı yol çizgi boyaları üretilmiştir. Üretilen yol çizgi boyalarının Karayolları Genel Müdürlüğü’nün istediği standartlarda olduğu örtme, yüzey kuruma, dip kuruma, aşınma direnci ve kromatiklik koordinatları gibi boya testleri ile belirlenmiştir. Montmorillonit, kopolimerin film özelliklerini geliştirmiştir. Ancak katkısız kopolimerli bağlayıcı ile montmorillonit bazlı nanokompozit bağlayıcının kullanıldığı boyaların özellikleri arasında önemli bir fark görülmemiştir.
Anahtar Kelimeler:

poli(bütil akrilat-ko-metil metakrilat), nanokompozit, yol çizgi boyası, emülsiyon polimerizasyonu

SYNTHESIS OF POLY(BUTYL ACRYLATE-CO-METHYL METHACRYLATE)/NANCOMPOSITES AND ITS USE IN ROAD MARKING PAINT

In this study, poly (butyl acrylate-co-methyl methacrylate) copolymer which has been used as binders in water-based coating materials  is intended to be synthesized by emulsion polymerization. In order to improve the film properties of the resulting copolymer, polymer-nanocomposites were obtained via Na-montmorillonite. By using Differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA), glass transition temperature and thermal stability was determined, respectively. DSC and TGA showed the improvement in thermal properties. It has also been found out through mechanical test that the mechanical strength of the pure latex increased. Water based road marking paints were produced by using pure latex and Na-montmorillonite reinforced copolymer. Produced road marking paint was in the limits of the General Directorate of Highways standards according to the dye tests of hiding power solid dry time, no pick up time, abrasion resistance and chromaticity coordinates. Montmorillonite enhanced copolymer film properties. However, no distinction was observed between the properties of pristine copolymer containing paint and nanocomposite copolymer containing paint.
