Предлагаемый способ заключаетс в получении I прс1зрачных и полупрозрачйых 1-еплавких и нерастворимых фенопластов ИЗ: фенола и крезолов. Конденсаци осуществл етс сначала нагреванием фенола с сухим гекса в присутствии небольшого количества спирта, с перево цдм полученной смолы типа новолвка j bj резольную при помощи допол|йительНой I обработки новблака в спирто вом растроре тeкcaмeтиJ1eнтeтpамином . Количество гексаметилентетрамина , необходимое дл образовани новолака , ; определ етс , примерно, на 12 мол. фенола 1 мол, гекса, а на резол требуетс на 13 мол. фенола около 2,25 мол. текса. Полученную в спиртовом растворе ;смолу высушивают под уменьшенным давлением, растворитель отгон ют , смолу хо|эошо измельчают и без введени наполнителей прессуют при давлении от 200 до 600 кг/см- поверхности прессуемого издели . Конденсацию с гексаметилентетрамином можно проводить в присутствии небольшого количества едких щелочей, как, например, едкий натр, гидрат окиси бари и т. д. Дл замедлени ;реакции конденсации можно вводить 8 продукты конденсации или в исходный |фенол глицерин, гликоль или амиловым спирт. При примененииThe proposed method consists in obtaining I prc1e and translucent 1-meltable and insoluble phenolic plastics FROM: phenol and cresols. The condensation is carried out first by heating a dry hex phenol in the presence of a small amount of alcohol, transferring the obtained resin of the type jbj resole by means of an additional Novolak I treatment in an alcohol ratchetrothermite. The amount of hexamethylenetetramine required to form a novolak; measured at about 12 mol. phenol 1 mole, hex, and the resol is required at 13 mole. phenol about 2.25 mol. tex. The resin obtained in an alcoholic solution; the resin is dried under reduced pressure; the solvent is distilled off; the resin is finely ground and, without the introduction of fillers, is pressed at a pressure of 200 to 600 kg / cm-surface of the compressible product. Condensation with hexamethylenetetramine can be carried out in the presence of a small amount of caustic alkali, such as caustic soda, barium hydroxide, etc. To slow down the condensation reaction, you can enter 8 condensation products or in the original phenol glycerol, glycol or amyl alcohol. When applied
ЭТОГО метода можно получить прозрачные органические стекла нтарного цвета или окрашенные при помощи специальных красителей в различныецвета . В отличие от литых фенольнь1Х прозрачных пластиков данные фенопласты будут отличатьс высокой механической прочностью и высокими электроизол ционными свойствами. Так например , нормальный брусок дает прочность на удар от 10 до 12 К21см, а пробивной градиент выра аетс в 20000- 30000 вольт на 1 -ifjf толщины. Предлагаемый способ может дать возможность получать .как продукты галантерейногохарактера , так и высокого качества электроизол ционные материалы.This method can be obtained transparent organic glass amber-colored or painted with special dyes in various colors. Unlike cast phenolic transparent plastics, these phenolic plastics will be distinguished by high mechanical strength and high electrical insulation properties. So, for example, a normal bar gives impact resistance from 10 to 12 K21cm, and the penetrative gradient is expressed in 20000-3000 volts per 1 -ifjf thickness. The proposed method can give the possibility to obtain both products of a haberdashery character and high quality electrical insulation materials.
Дл получени полупрозрачных продуктов рекомендуетс при второй фазе конденсации вводить в спиртовые растворы смолы вместе с гекса жирные кислоты или масла, растворимые в. спирте, как например, касторовое и т. д. Количество масел колеблетс в пределах от 2 до 20%.In order to obtain translucent products, it is recommended to introduce fat soluble acids or oils soluble in alcohol solutions of the resin in the second phase of condensation. alcohol, such as castor oil, etc. The number of oils ranges from 2 to 20%.
Конденсаци с гекса дает возможность более легко получать прозрачные продукты, так как при этой реакции конденсации выдел етс аммиак, но не выдел етс вода, что было раньше установлено работами Лебаха, Бэкеланда , Редмана, Кебнера и др.
