Abstract

In order to maximize the potential of Ukrainian carbonate deposits in composition of waterborne paints were studied properties and their possible for modification by mechanochemical activation in the presence of CH3Si(OH)2OK.

Filtration coefficient, size of the effective specific surface, hydrophilic factor for initial and modified materials are determined during the work in the methodology of moistening research at leaking of polar and nonpolar liquids.

Based on the data can be argued that the surface modification of carbonate by hydroalcoholic solution CH3Si(OH)2OK makes its surface less hydrophilic, increases dispersion, reduces the size of interparticle capillary, increases the effective surface area and will enhance the properties of the finished composite materials.

Thus, investigations have shown that at filling of waterborne paints by carbonates of Ukrainian deposits is reasonable to conduct their preliminary mechanical activation using hydroalcoholic solution CH3Si(OH)2OK at a concentration of 0,5 % wt, because this treatment allows to bring the nature of carbonate surface to film former and improve moistening and distribution of the filler particles in the coating structure.
