Combined Extender Pigments Based on Industrial Wastes

Abstract

A pigment-filler for paints is developed based on iron ore enrichment wastes i.e. tailings ferruginous quartziteenrichment (TFQ) and for dust sleeve filters while ceramsite production. The samples of powder materials having a particle size less than 50 microns were used for the experiments. The samples were prepared according to a formulation of paints and varnishes "Plant Paints Quil" (Belgorod). The samples of the primer were tested on the following parameters: dispersibility, the degree of grinding, relative viscosity, hardness, drying time, adhesion and elasticity. The results showed that the proposed pigment-filler is of the same quality as the materials traditionally used for the production of primers. Thus the proof of the possibility and prospects of using TFQ and ceramsite dust as pigments-fillers in the manufacture of paints and varnishes is evident.
