Description
Изобретение относитс к способам получени клеез холодного отверждени на основе фенольных смол, полученных из подсмольных вод при сухой нерегонке сланцев.The invention relates to methods for producing cold curing adhesives based on phenolic resins obtained from the podsmol waters with dry non-distillation of shale.
Супшость изобретени состоит в том, что вакуумную фракцию 240- 320° (диметилрезорцнны), полученную при разгонке фенолов, конденсируют в смеси с формалином, этиловым спиртом н этилеигликолем.The invention is based on the fact that the vacuum fraction of 240-320 ° (dimethylresistant), obtained by distillation of phenols, is condensed in a mixture with formalin, ethyl alcohol and ethylaglycol.
Преимун1,еством предложенного способа- полученн названных клеев вл етс расширение сырьевой базы дл этих клеев и возможность улучнюни качества получаемой продукции .The advantage of the proposed method, the obtained adhesives is the expansion of the raw material base for these adhesives and the possibility of improving the quality of the products obtained.
Полученне названных клеев ocyHieствл етс следующим образом.The ocyHie adhesives obtained are as follows.
Вначале приготавливают фенолальдегидную смолу конденсацней смеси диметилрезорцинов с формальдегидом в присутствии одноатомных и многоатомных спиртов с введением в конце конденсации едкого натра.First, phenol-aldehyde resin is prepared by condensing a mixture of dimethylresorcinol with formaldehyde in the presence of monohydric and polyhydric alcohols with the introduction of caustic soda at the end of condensation.
Дл приготовлени фенолальдегндной смолы берут продукты в следуюищх соотношени х:For the preparation of phenolic resin, products are taken in the following proportions:
диметилрезорцин 100%-ныйdimethylresorcinol 100%
138 вес.ч.;138 parts by weight;
формалин 37%-ньн 1 formalin 37% n 1
40. ; этиловый спирт 41,4 ; этиленг-тиколь (100 %)40.; ethyl alcohol 41,4; ethylene ticol (100%)
27..27 ..
Смесь тщательно перемешивают н конденснруют при 40-43° в течение 1 часа. Затем температуру реакционной смеси повышают до 96-98° н продолжают конденсашпо при этой температуре еще 1 час. После охлаждени полученной смолы в нее вводитс 15 вес. ч. ускорнтел - 20°;о-ного водного раствора едкого натра.The mixture is thoroughly stirred and condensed at 40-43 ° for 1 hour. Then the temperature of the reaction mixture is raised to 96-98 ° n, the condensation is continued at this temperature for another 1 hour. After cooling the obtained resin, 15 wt. including accelerator - 20 °; of the aqueous solution of caustic soda.
Дл приготовлени кле берут 100 вес. ч. полученной смолы добавл ют 9-11 вес. ч. отвердител - пароформа, после чего смесь тщательно перемешивают до образовани однородного раствора.For the preparation of adhesive take 100 weight. including the resulting resin is added 9-11 weight. the hardener is a vapor form, after which the mixture is thoroughly mixed until a uniform solution is formed.
