Description

The subjects of investigation: the bentonite clay of Kudrino deposits, organomontmorillonite with melamine and cetyltrimethylammonium cations. The purpose of research is obtainment and identification of montmorillonite organoclays with cetyltrimethylammonium and melamine cations. The research methods: IR spectroscopy and thermogravimetric analysis were used to identify the starting and the resulting compounds. Basic approaches to the modification of the natural bentonite clay were tested: laundering, getting montmorillonite, translation of montmorillonite to Na-type montmorillonite and obtaining organoclays with melamine and quaternary ammonium cations. The nanocomposites of modified organoclays with a copolymer of ethylene and vinyl acetate were synthesized. Scientific novelty of the results: bentonite clay of Kudrino deposits as raw material to produce nanocomposites was investigated; it was found that the addition of organic cations greatly improves the compatibilityof organoclay with the polymer and produces nanocomposites with the maximal distribution of the nanoclays in the polymer structure. The practical importance of research is related to the expected positive effect of the addition of obtained organoclays in intumescent fire retardant coating, which is in improving the flame retardant efficiency of the coating of the traditional composition (ammonium polyphosphate / polyol / amine / copolymer).
