| Abstract. | The properties of polymer composite materials are largely determined by their structure. To obtain a material with the given properties, we should develop its structural parameters providing necessary complex of operational and technical characteristics. Traditionally, the material structure is studied in three levels: the macro-level (the macro-structure – the structure of the material is visible with the naked eye); micro-level (micro-structure – the structure is visible through a microscope); the molecular-ion level (physical and chemical methods of research – electron microscopy, thermal imaging, x-ray analysis, etc.). In turn, raw materials composition and technological modes of manufacture influence on the structure of materials.The microstructure of disperse systems is largely determined by the technological parameters of the mixing of the initial components. Therefore, the aim of this stage of work is the optimization of the technological parameters of production (the time of mixing and speed of the mixing) of disperse systems on the basis of polyisocyanate and polysilicate of sodium. The methods of optical microscopy, it was established that in the liquid state modified organo-inorganic binders are a two-phase micro-heterogeneous leoprofile emulsion. Dispersion medium is organic oligomer of resin, and disperse particles of spherical form presented the inorganic component water solution of sodium silicate. |
