Özet:

  We performed analysis of the processes of interaction in the systems of chalks with a modifier (potassium methylsiliconate) and acrylic film forming material. The studies were conducted with the help of infrared spectroscopy. The purpose of the work was to estimate the level of development in the processes of interaction in the examined systems. Quantitative parameters of the basic characteristic bands in charge of the valence vibrations of reactive groups of chalks and film forming agent are determined. The shifts in characteristic bands of the IR spectra, changes in their intensity are indicated. The results of present work testify to the fact that in the systems chalk – potassium methylsiliconate – acrylic film forming agent, the processes of interaction proceed with the participation of adsorbed water, bonds C=O and C–O of chalks. We also noted intensive inculcation of polymer (by the intensity of bands characteristic for the С–Н bonds) by 2–8 times with the use of modified chalks in comparison with the starting ones.An increase in the interaction between chalks and the film-forming agent by the modification of this filler is of interest for creating functional composite materials as it provides for an improvement in their properties.
