Investigation of the effect of cyclic borate ester groups in acrylic copolymers on paint and varnish coatings

Abstract

In this study, cyclic borate ester-bearing methacrylic monomers were created and employed to synthesize acrylic copolymers with varying boron acrylate monomer contents (5, 10, and 20%). The monomers, methyl methacrylate, butyl acrylate, acrylic acid, and boron acrylate, were used to synthesize all of the polymers using free radical polymerization in a solvent medium. The polymers were characterized using FTIR (Fourier transform infrared spectroscopy), DSC (differential scanning calorimetry), Gel permeation chromatography (GPC), 1H and 11B NMR (proton and boron nuclear magnetic resonance), and HPLC. Metal surfaces, such as sheet metal, galvanized steel, and aluminum, were covered with varnish and paint compositions that had a fixed thickness. Contact angle value, glossiness, hardness, drying time, pot life, yellowing resistance, and gloss loss following UV were all measured to assess the coatings' physical characteristics. According to the findings, adding more borate ester groups to polymers increased their hardness as well as decreased the drying time of the coatings. When compared to the binders used in commercially available paints, the polymer with 10% boron acrylate monomer can be utilized to produce paints and varnishes with equal or superior physical properties.

Akrilik kopolimerlerdeki siklik borat ester gruplarının boya ve vernik kaplamalara etkisinin araştırılması

Abstract

Bu çalışmada, siklik borat ester içeren metakrilik monomerler oluşturulmuş ve değişen bor akrilat monomer içeriklerine (%5, 10 ve 20) sahip akrilik kopolimerlerin sentezlenmesinde kullanılmıştır. Monomerler, metil metakrilat, bütil akrilat, akrilik asit ve boron akrilat, bir solvent ortamında serbest radikal polimerizasyonu kullanılarak tüm polimerleri sentezlemek için kullanıldı. Polimerler, FTIR (Fouirer Transform Kızılötesi Spektrofotometre), DSC (Diferansiyel Tarama Kalorimetrisi), Jel Geçirgenlik Kromatografisi (GPC), 1H ve 11B NMR (Proton ve Bor Nükleer Manyetik Rezonans) kullanılarak karakterize edildi. Sac, galvaniz çelik, alüminyum gibi metal yüzeyler sabit kalınlıkta vernik ve boya bileşimleri ile kaplanmıştır. Kaplamaların fiziksel özelliklerini değerlendirmek için temas açısı değeri, parlaklık, sertlik, kuruma süresi, kap ömrü, sararma direnci ve UV sonrası parlaklık kaybı ölçülmüştür. Elde edilen bulgulara göre, polimerlere daha fazla borat ester grubu eklenmesi, kaplamaların kuruma süresini azalttığı gibi sertliklerini de artırmıştır. Piyasada bulunan boyalarda kullanılan bağlayıcılarla karşılaştırıldığında, %10 bor akrilat monomer içeren polimer, fiziksel özellikleri eşit veya daha üstün olan boya ve verniklerin üretilmesinde kullanılabilir.
