Description
Изобретение относитс к способам антисептировани наружных дерев нных конструкций трудновымываемыми антисептиками и может быть применено дл пропитки, например, дерев нных столбов лнННЙ электропередач и св зи. Известен способ получени трудновымываемого антисептика дл древесины 1путем последовательной ее обработки веществами, образующими малорастворимые соединени . Дл получени токсичного дл дереворазрущающих г.рибОВ, не требующего длительного периода фиксации состава по описываемому способу предложено раствор эквивалентных количеств борной «ислоты, пвнтаэритрита и хлористого кальци нагрезчть иотстаивать, а также осаждать трудновымываемьтй пеетаэритриборат кальци . Дл получени трудновымываемого антисептика 145 г пентаэритрита и 65 г борной кислоты раствор ют перемещиванием в 750 мл воды при нагревамии. Затем добавл ют в раствор 59 г СаСЬ-бН О соли и Продолжают перемещивание и нагрева .ние до полного растворени соли. Раствор охлаждают, отфильтровывают и примен ют дл пропитки древесины. щий это количество аммиака или 23,5 г или 31 л газообразного NHs, или раствор, содержащий 47 г NaOH. В результате обработки в древесине получаетс малорастворима кальциева соль пентаэритритборной кислоты. Препарат обладает свойствами антипирена и не вызывает коррозии металлов. Древесина, защищаема препаратом, «ап .ример древесностружечные и другие плиты, в процессе эксплуатации ие выдел ет вредных дл человека летучих примесей. Проведенные испытани на вымываемость в течение мес ца (по ГОСТ 11540-65) показали , что сум.марна вымываемость в течение мес ца не превышала 10%. Предмет изобретени 1. Способ получени трудновымываемого антисептика дл древесины путем последовательной ее обработки веществами, образующими малорастворимые соединени , отличаюи ийс тем, что, с целью обеспечени возможности получени токсичного дл дереворазрушающих грибов, не требующего длительного периода фиксации состава, раствор ют в -воде эквивалентные количества бордой кислоты, пентаэритрита и хлористого кальци , нагревают ц отстаивают раствор, осаж& дают трудновымываемый пентаэритгриборат кальци второй прЬПиткой щелочью, например водным раствором аммиака. 4 2. Способ по п. 1, отличающийс тем, что пентаэритриборат осаждают обработкой газообразным аммиаком.The invention relates to methods of antisepticizing external wooden structures with hardly removable antiseptics and can be applied to impregnate, for example, wooden pillars of low-voltage electricity transmission and communication. A known method of obtaining a hard-to-washable wood preservative is 1 by sequentially treating it with substances that form poorly soluble compounds. To obtain toxic for wood-destructive gribov, which does not require a long period of fixation of the composition according to the described method, a solution of equivalent amounts of boric acid, pvneerythritol and calcium chloride is proposed to heal and settle, as well as precipitate calcium-rich erythrocyte. To obtain a hard-to-remove antiseptic, 145 g of pentaerythritol and 65 g of boric acid are dissolved by transferring to 750 ml of water while heating. Then, 59 g of CaC-bH O salt is added to the solution and the transfer and heating is continued until the salt is completely dissolved. The solution is cooled, filtered and used to impregnate the wood. This amount of ammonia is either 23.5 g or 31 liters of gaseous NHs, or a solution containing 47 g of NaOH. As a result of processing in wood, a soluble calcium salt of pentaerythritolboric acid is obtained. The drug has flame retardant properties and does not cause corrosion of metals. The wood protected by the preparation, “up. Chipboard and other plates, in the process of exploitation does not release volatile impurities harmful to humans. The tests for washout during the month (according to GOST 11540-65) showed that the total washout during the month did not exceed 10%. The subject matter of the invention 1. The method of obtaining a hard-to-washable wood preservative by successively treating it with substances that form poorly soluble compounds, is different in that, in order to ensure the possibility of obtaining toxic to wood-destroying fungi that do not require a long period of composition fixation, the water equivalent to Bordeaux acid, pentaerythritol and calcium chloride, heat, c, defend solution, precipitate & give the pentaerythritic calcium that is difficult to wash out with a second alkaline drink, for example, an aqueous solution of ammonia. 4 2. The method according to claim 1, characterized in that the pentaerythritolate is precipitated by treatment with gaseous ammonia.
