Alüminyum birçok üstün özelliklere sahip olmasına rağmen kolayca çizilme
ve aşınma, çok çabuk korozyona uğrama, kir ve leke tutma gibi bazı
dezavantajlara sahiptir. Alüminyum yüzeyine hibrid kaplama yapılarak aşınmaya,
çizilmeye, korozyona, kir ve lekeye karşı dirençli hale getirmek aynı zamanda
görsel ve dekoratif özellikler kazandırmak mümkündür. Bu çalışmada yüksek
miktarda flor içeren yapılar ile silisyum içerikli yapılarla reaksiyona
sokularak flor içerikli inorganik faz elde edildi. Hibrid yapının organik kısmı
ise epoksi akrilat, hekzan diol diakrilat ve UV başlatıcıdan oluştu. Organik ve
inorganik kısımların manyetik karıştırıcı yardımıyla homojen bir şekilde
karıştırılmasıyla flor içeren hibrid kaplama formülasyonları yüzeye uygulandı.
Farklı içeriklere sahip formülasyonlar UV ışınlarıyla sertleştirilerek
yüzeylerin kaplama performansları incelendi. Alüminyum levha yüzeyleri UV
ışınlarıyla sertleşebilen flor içerikli hibrid malzemeyle kaplanarak aşınmaya,
sürtünmeye, çizilmeye, korozyona, kir ve lekelere karşı dirençli hale
getirildi. Bununla beraber yüksek parlaklıkta görsel ve dekoratif özelliklere
sahip bir yüzey elde edildi.

Improvement of surface properties of aluminum sheets with UV curable hybrid coatings

Öz

Although aluminum has many superior properties, it has some
disadvantages such as scratching and abrasion, very quick corrosion, dirt and
stain retention. It is possible to make the aluminum surface resistant to
abrasion, scratching, corrosion, dirt and stains by giving a hybrid coating at
the same time to give visual and decorative features. In this study, fluorine
containing inorganic phase was obtained by reacting high amounts of fluorine
containing structures with silicon containing structures. The organic part of
the hybrid structure consisted of epoxy acrylate, hexane diol diacrylate and UV
initiator. Hybrid coating formulations containing fluorine were applied to the
surface by mixing the organic and inorganic parts homogeneously with a magnetic
stirrer. The formulations with different contents were hardened by UV rays and
the coating performance of the surfaces was examined. Aluminum sheet surfaces
were coated with fluoride-containing hybrid material which was hardened by UV
rays and made resistant to abrasion, rubbing, scratching, corrosion, dirt and
stains. However, a surface with high visibility and decorative features was
obtained.
