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.

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

Öz

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.
