Resumo
Paint is a prevalent type of surface of coating well known to most people. It is an easy-to-apply product, with
excellent physical and chemical resistance and a wide range of applications. The function of a paint is to protect
and beautify amongst other properties. Paints are formed using five components: resin, pigments, fillers, solvents
and additives. This work deals with a specific type of paint, composed of a water-based acrylic emulsion, whose
film formation is by coalescence and used to coat walls and other surfaces. The aim of this innovative research
was to evaluate the effect of the addition of cellulosic dispersion of waste paper tissues treated by electron beam
irradiation to an acrylic emulsion-based paint. The methodology used was a case study carried out at the Nuclear
and Energy Research Institute that consisted of adding aqueous dispersions of cellulosic wipes with mass
concentrations varying from 0.1% to 10% in deionized water, and treated by electron beam processing with
absorbed doses from 5 kGy to 50 kGy. The results obtained followed the parameters of the Abrafati Sectorial
Quality Program. The main sample parameters analyzed were specific density, which reached an average of
1.35 g/cm3
; and covering power, whose value of 93.55% was above the specified limit (minimum of 90%).
Among other results obtained, improvements in appearance, applicability and functionality were significant. It
was concluded that this research constitutes an incremental improvement to the acrylic emulsion paints segment,
and environmental sustainability, through the reuse of cellulosic tissue residues.
