ТЕРМОДЕСТРУКЦИЯ СТЕБЛЕЙ БОРЩЕВИКА СОСНОВСКОГО, МОДИФИЦИРОВАННЫХ МОНОЭТАНОЛАМИН (N→B)-ТРИГИДРОКСИБОРАТОМ

Abstract

In the presented work, the process of thermodegradation of unmodified and borazote-modified crushed stems of Sosnovsky's Heracleum by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) was investigated. The general purpose of the study is to determine the decomposition temperature of the main chemical components and the values of mass loss of unmodified and modified crushed stems of Sosnovsky's heracleum to establish the conditions for the production of thermal insulation materials based on modified crushed stems. The concentration of the used modifier was 10%, 30% and 50% of monoethanolamine(N→B)trihydroxyborate (MEATHB). The data obtained allowed us to conclude that the use of 30% and 50% MEATHB modifier reduced the magnitude of mass loss compared to the control samples. Thus, the optimal concentration of the modifier different 30% was established for the manufacture of composites from modified crushed stems of Sosnovsky's heracleum with the possibility of processing and/or drying at temperatures less than 100°C.
