The environmental impact reduction principles of bioprotective paintwork material during the wood surface paint

Abstract

A bioprotective paintwork materialfor wood surface with reduced content ofbiocide additive has been developed. The fungi inertness of acrilyc, styrene-acrylic and vinyl-acetate-ethylene films on the base of its dispersions has been investigated. It has been shown that the most stable film to the mold fungi when the changing of mechanical properties and chemical struct ure is a film on the base of acrylic dispertion. The influence of pigments, their volume concentrationand paint surface on the coatingfungi inertness coatingwas studied. It was noticed that zinc oxide among zinc pigment decelerates fungi growthbetter than others. The main principles ofenvironmental impact reduction of abioprotective paintwork material have been defined. They are: the choice a biostable film binder, fungitoxic pigment and inert filler use, their quantities are defined on the pigment volume concentration, except the component which can stimulate fungi growth.
