Изобретение относитс к состава, дл модификации .древесины и может Выть использовано в деревообрабатывающей промышленности.The invention relates to a composition for modifying wood and can be used in the woodworking industry.
JtssecTHH составы дл пропитки дре-весины , содержащие в качестве основы синтетические смолы и) модифицирующие добавки, например карбамидно-формальдегидную смолу, i м одифицирова.нную фу-рановыми соединени ми j|l3.JtssecTHH compounds for impregnation of wood, containing synthetic resins as bases and i) modifying additives, for example, urea-formaldehyde resin, are odifferential furan compounds j | l3.
Однако такие составы не придают древесине посто нной водостойкости И требуют дл протекани полимериза1ции инертную среду, However, such compositions do not give wood a constant water resistance, and an inert medium is required for polymerization to proceed.
Наиболее близким к изобретению в л етс состдв дл пропитки древесины, содержащий раствор фенолоспирта с мо дафицирующей добавкой - фенилтоихлорсилйнГа .The closest to the invention is the composition of wood for impregnation, containing a solution of phenol alcohol with a modifying additive, phenyl toylchlorosiline.
К недостаткам этого состава отно .ситс высока токсйчность и низка жизнеспособность, что затрудн ет его промышленное использование.The disadvantages of this composition are high toxicity and low viability, which makes its industrial use difficult.
Цель.изобретени повашение жианеспособности состава и снижение его токсичности достигаетс тем, что в .качестве лгоднфйцируюадей добавки вэ тН мочевино-формадьдегидна смола, при следушЕ; Г} соотнс нени х компонентов (веСс%). The purpose of the invention is to improve the liquidity of the composition and reduce its toxicity by the fact that, as a fruit, the additive of the additive is TN urea-formahyde resin, with the following; G} of the ratios of the components (all%).
