Development of Surface Coating based Hybrid Acrylic Copolymers for Coating Application, Preparation, Characterization and Processing

Abstract

In this study, series of hybrid emulsion copolymers with different composition ratios of acrylic acid, methylacrylic
acid with butyle-acrylate, methyl-metha-acrylate, polyvinyl alcohol were generated. The preparation
was performed in a batch reactor on an industrial scale to obtain the resulting resin. While applying various
processes of emulsion polymerization, batch polymerization was chosen to find optimum conditions by
investigating the parameters of the monomer percentages, initiators, temperature and time. Dodecyl Benzene
Sulphonic acid SDBA as emulsifier, as well as sodium dodecyl sulfonic acid SDBAS as co-emulsifier as
redox couple initiator have been chosen as the best and most effective initiators to hybrid acrylic resin
processing Water-dispersed acrylic resin was developed as a hydrophilic monomer, utilizing acrylic acid.
To avoid gelatin and agglomeration, the reaction temperature of the acrylic resin preparation was taken
for 4 hours at 70oC. To understand the effect of silane coupling agent on the properties of hybrid emulsion
copolymers, in the presence of trimetyl-chloro saline. FTIR spectroscopy, 1HNMR spectra, thermal analysis
as well as mechanical tests were widely studied confirmation of the hybrid acrylic resins. The various physicchemical
properties of hybrid emulsion acrylic copolymers including density, viscosity, chemical resistance
and volatile matter were studied. The results show that hybrid emulsion acrylic copolymers are readily
soluble in aprotic polar solvents such as (Toluene, Acetone, Benzene, xylene, DMF, DMSO, Methanol, and
ethanol) without being in need for heating. The emulsion copolymers obtained had a great solid content as
well as have been used as binder in emulsion paints. These polymers have very useful properties such as
high anticorrosive and chemical resistance, the experimental results reveal.
