Abstract
This article discusses the process of developing a liquid glass composition designed to protect wood from fire. The main attention is paid to the selection of components such as sodium liquid glass as a binding agent, silica as a filler and a foaming agent to improve the properties of the coating. These components are chosen for their ability to form a protective layer, which swells when heated, significantly increasing the flame retardant properties of the material. The research methods included a detailed analysis of the constituent components of the flame retardant composition and experimental testing of its effectiveness. Laboratory tests were carried out, including the preparation of wood samples, their processing with the developed composition and the subsequent study of their behavior under the influence of high temperatures. The results show that the flame retardant coating effectively protects wood and belongs to the first group in terms of flame retardant effectiveness, being the highest indicator among similar materials. It is recommended to use this composition in a single-layer design to reduce the flammability of wooden structures as effectively as possible. The technological efficiency of the new composition is ensured due to the minimum number of components used and the availability of high-quality raw materials.
