Advanced Sol-Silicate Paint

Abstract

Deficiencies of silicate paints are revealed. Novel sol-silicate paint obtained by mixing liquid glass and silica sol has been developed. The nominal viscosity of the paintwork was determined using a VZ-4 viscometer. The relative hardness of the coatings was determined using the M-3 pendulum device. The tensile strength (cohesive strength) was determined on a tensile testing machine IR 5057-50. Analysis of the IR spectra shows that the presence in the composition of the polysilicate binder of various polymer silica provides increased durability of silicate coatings. Dependence of the relative hardness of the films based on the polysilicate solution on their thickness is calculated. The presence of polymer varieties of silica in the polysilicate binder was established, which provides increased durability of silicate coatings. A correlation between the content of high-polymer fractions of silicon-oxygen anions in the polysilicate solution and the tensile strength of the films was revealed, which consists in the fact that with an increase in the content of SiO2, an increase in the tensile strength of the films is observed. Thus, in accordance with its exploitation characteristics, the developed sol-silicate paint can be used for decoration of both external and internal walls of buildings.
