Description
1.one.
Изобретение относитс к деревообрабатывающей промышленности, а именно к защите древесины от гниени и возгорани . Предлагаемый препарат целесообразно использовать при строительстве гражданских и промышленных зданий, а также при ремонтном консервировании, в том числе и уникальных пам тников.FIELD OF THE INVENTION The invention relates to the woodworking industry, in particular to the protection of wood from rotting and ignition. The proposed preparation should be used in the construction of civil and industrial buildings, as well as in the maintenance canning, including unique monuments.
Известен препарат дл зашиты древе сины от возгорани , включающий формалдегид-дициандиамид , мочевину, соль амм ВИЯ и фос(|)орной кислоты l.A known preparation for the protection of wood from a fire, including formaldehyde-dicyandiamide, urea, amm VIV salt, and phos (|) hydrochloric acid l.
Такой препарат не способен защищать древесину от биоразрушений.Such a drug is not able to protect the wood from biodegradation.
Наиболее близким к изобретению вл етс препарат, содержащий диаммонийфосфат и фторид натри 2.Closest to the invention is a preparation containing diammonium phosphate and sodium fluoride 2.
Однако данный препарат, эффективный дл защиты древесины от гниени и возгорани , имеет высокую корродирующую способность , что .з 1трудн ет использование пропитанной древесины в гвоздевых, конструкци х или в конструкци х, где примен етс металлический крепеж. К тому жеHowever, this preparation, which is effective in protecting wood from rotting and burning, has a high corrosive ability, which makes it difficult to use impregnated wood in nails, structures or structures that use metal fasteners. Besides
он резко повышает гигроскопичность пропитанной древесины.it dramatically increases the hygroscopicity of the impregnated wood.
Цель изобретени - создание препарата с пониженной корродирующей способностью и менее гигроскопичного.The purpose of the invention is to create a drug with reduced corrosive ability and less hygroscopic.
Это достигаетс тем, что препарат дополнительно Содержит мочевину при следующем соотнощении компонентов, . % П( массе:This is achieved in that the preparation additionally contains urea at the following ratio of components,. % P (mass:
Фторид натри , -1О-30Sodium fluoride, -1O-30
