Polysilicate binding for silicate paints

The results of the study provide information on the resistance of coatings based on the solof silicate paint in the process of freezing and thawing. It was found, that coatings based on sol silicatepaints are characterized by a higher resistance compared of silicate coatings. It is shown, that thecoatings withstood 50 cycles of alternate freezing and thawing. The surface energy of the coatingswas calculated using the critical surface tension of the fluid at the interface with the solid. Thedispersion contribution in the intermolecular interaction between the particles of the coatings wasestimated. The values of the surface tension of the coatings and the values of the dispersioncomponent of the surface energy of the coatings — the complex Hamaker constant — are calculated.It was revealed, that after testing a decrease in the values of the Hamaker constant is observed. It wasestablished, that after testing for frost resistance, the values of the Hamaker constant for coatingsbased on sol of silicate paint are higher compared to coatings based on silicate paint.

The results of the study the fire safety of coatings, based on silicate and sol silicate paints, are presented. The rapid method of the fire tube (based on the definitions of the duration of self-combustion or smoldering and on the mass loss of the sample after exposure to an open flame) established that the coatings belong to the group of non-flammable material, for coatings, based on poly-silicate solutions, have a lower loss of mass, in comparison with coatings based on liquid glass. At the flammability test on the TPR it was established, that coating based on potassium liquid glass and potassium poly-silicate solution did not ignite seen, even at a temperature of 760 degrees. There is no smoke emission. However, a change in the shape and color was recorded. The weight loss of the sample of the coating, based on potassium liquid glass, was 30.14% by weight, and the coating sample, based on the potassium poly-silicate solution, was 27.14%. The evidence of improvement of fire hazard characteristics of coatings based on poly-silicate solutions is obtained.
