Description
Изобретение относитс к производству клеев и может быть использовано в деревообрабатывающей промышленности дл склеивани древесных материалов .The invention relates to the manufacture of adhesives and can be used in the woodworking industry for gluing wood materials.
Целью изобретени вл етс повышение прочности и водостойкости клеевого шва, снижение токсичности при отверждении .The aim of the invention is to increase the strength and water resistance of the adhesive joint, reducing toxicity during curing.
Клей готов т следующим образом.The adhesive is prepared as follows.
В.емкость дл смешивани отвешивают карбамидойормальдегидную смолу, 20%-ный раствор эпоксиалкилрезорциновой смолы в метилэтилкетоне и тщательно перемешивают. Перед склеиванием в эту массу ввод т 5%-ный водный раствор дигидрохлорида гидразина , после чего массу тщательно перемешивают в течение 1-2 мин.B. Capacity for mixing is weighed with urea-formaldehyde resin, 20% solution of epoxyalkylresorcin resin in methyl ethyl ketone and mix thoroughly. Before gluing, a 5% aqueous solution of hydrazine dihydrochloride is introduced into this mass, after which the mass is thoroughly mixed for 1-2 minutes.
Состав, соотношение компонентов и йизико-механические свойства предлагаемого и известных клеев и склеенных на их основе материалов приведены в таблице.The composition, the ratio of components and the physical-mechanical properties of the proposed and known adhesives and glued materials based on them are given in the table.
