Abstract

The effects of components of intumescent systems based on silane-terminated polyether (STP) polymers on their thermolysis character were studied. Thermal analysis and fire-resistance tests showed that neither the molecular weight of the STP polymer, nor a moderate change in the ratio of components in the intumescent system relative to the selected base composition, has a significant effect on the thermolysis, whereas a change in the amounts of fillers such as kaolin and, in particular, titania, provides doubling of the fireproof rating of the studied coatings due to the structuring of the char foam formed upon thermal destruction and acts as a heat-insulating coating. These results may be of significant importance in the development of heat-expanding fire-protection compositions based on STP polymers.

期刊介绍: Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
