Description
Изобретение относитс к области строительных материалов и предназначено дл получени огнестойкой древесины. Изобретение может быть использовано в деревоббрабатывающей промышленности и в строительстве.The invention relates to the field of building materials and is intended to produce fire resistant wood. The invention can be used in the wood processing industry and in construction.
Известен состав дл огне-биозащиты древесины, включающий буру, борную кислоту, сульфат меди, бихромат натри и концентрированную уксусную кислоту Ci,A known composition for fire bioprotection of wood, including borax, boric acid, copper sulfate, sodium dichromate and concentrated acetic acid Ci,
Известен состав дл огне-биозащиты .древесины, включающий буру, борнуюкислоту и воду 2,A known composition for fire bioprotection. Wood, including borax, boric acid and water 2,
Недостатком состава вл етс то, что он имеет низкую растворимость при комнатной температуре, легко вымываетс из древесины, что ведет к снижению огнезащиты, и не позвол ет примен ть пропитанную древесину во влажных услови х.The disadvantage of the composition is that it has low solubility at room temperature, is easily washed out of wood, which leads to a decrease in fire protection, and does not allow the use of soaked wood in wet conditions.
Цель изобретени - повышение огнестойкости древесины и снижение водовлагопоглощени .The purpose of the invention is to increase the fire resistance of wood and reduce water absorption.
Поставленна цель достигаетс тем, что состав дополнительно содержит триэтаноламинборат при следующем соотношении компонентов, мас.%:The goal is achieved by the fact that the composition additionally contains triethanolamineborate in the following ratio of components, wt.%:
