Improvement of fire retardant properties of wood materials

Abstract

Any kind of construction involves the use of wooden structures that require the achievement of an appropriate class of their fire hazard with the provision of the required fire protection indicators. Currently, fireproofing of wood materials is carried out mainly by impregnating wood with fireproofing compositions. And the search by scientists for relatively cheap and environmentally friendly fire retardant materials (flame retardants) for impregnating and treating wood is still relevant. This article discusses the role of fire retardant for wood material. The experimental study using 4% tetraethoxysilane is described. An optimal method of applying a composition for increasing fire resistance and a fire-retardant efficiency group of the test composition have been experimentally established. The positive effect of this composition on the fire-retardant properties of the wood chip board was also established. Time characteristics during soaking and drying of samples are recommended.
