ОABOUT
Изобретение относитс к способам склеивани карбамидным клеем иэде-ЛИЙ , например из древесины.BACKGROUND OF THE INVENTION The invention relates to methods for gluing with urea glue urea, for example from wood.
Известны способы скле вани путем нанесени на склеиваемле поверхно сти карбамидного кле , соединени 5 поверхностей и отверждени кле при температурах до в течение до 1 ч.There are known methods for gluing by applying a urea glue, bonding 5 surfaces and curing the adhesive at temperatures up to 1 hour on the bonding surface.
Известные способы требуют громоздкого I.,кассового оборудовани , 10 большого времени отверждени . Прочность склеивани часто не высока вследствие деструкции субстрата под дёйстанем примен емого кислого отвердат ел .15Known methods require bulky I., cash register equipment, 10 large curing times. The bonding strength is often not high due to the destruction of the substrate under the pressure of the acid used to cure it. 15
целью изобретени вл етс увеличение прочности склеивани и значитё ьНое сокращение времени отвержде№ . The purpose of the invention is to increase the bonding strength and significantly reduce the curing time.
Достигаетс это тем, что в состав кле ввод т 10-20 мас.%. четыреххпористого углерода, а отверждение провод т при нормальной температуре под действием ионизирующих излученийКлстрых электронов дозой от 9 до 10 мегарад в течение 12 - 15 с. Пример осуществлени способа склеивани фанеры клеем - карбамидной смолой М-19-62 - приводитс в таблице.This is achieved by the fact that 10-20 wt.% Are added to the adhesive. carbon, and curing is carried out at normal temperature under the action of ionizing radiation of strongest electrons with a dose of from 9 to 10 megarads for 12-15 s. An example of the method for gluing plywood with glue, M-19-62 carbamide resin, is given in the table.
Клеевые соединени при испытани х разрушаютс на 80% по слою древесины и имеют следующие показатели: Предел прочности по (ыванию при раст жении (ГОСТ 1143-41), кгс/см2 37 Предел прочности npii равномерном отрыве по методике ВИАМ, кгс/см 32When tested, glue joints are destroyed by 80% over a layer of wood and have the following characteristics: Tensile strength (stretching (GOST 1143-41), kgf / cm2 37 Tensile strength npii uniform separation according to the VIAM technique, kgf / cm 32
