Description
Исходным сырьем дл получени искусственных смол по предлагаемому авторами изобретени способу их приготовлени служат корни диKopacTynjero растени шаир из семейства ферул.The starting material for the production of artificial resins according to the method of their preparation proposed by the authors of the invention is the roots of the diopus Tyynjero shair of the ferul family.
Корни этого растени содержат от 55 до 62% углеводов и от 33 до 35% смолоподобных веществ, которые при конденсации с формальдегидом в присутствии щелочи или кислоты дают термореактивную смолу, пригодную дл изготовлени пресспорошков дл производства пластических масс.The roots of this plant contain from 55 to 62% carbohydrates and from 33 to 35% tar-like substances, which, when condensed with formaldehyde in the presence of alkali or acid, give a thermosetting resin suitable for making press powders for the production of plastics.
Искусственные смолы могут быть получены также и путем непосредственной обработки, измельченных корней формальдегидом, без предварительного выделени смолоподобных продуктов.Artificial resins can also be obtained by direct processing, comminuted roots with formaldehyde, without first isolating tar-like products.
В случае предварительного извлечени смолоподобных продуктов, конденсацию последних провод т исход из расчета 30-60 в. ч. 37%ного раствора формальдегида на 100 в. ч. выделенной смолы в присутствии 1-3 в. ч. едкого натра. В случае же непосредственной обработки корней на 100 в. ч. измельченного корн берут 20-40 в. ч, 37%-него раствора формалина. ОбОтв . редактор М. М. АкишинIn the case of preliminary extraction of tar-like products, the condensation of the latter is carried out on the basis of 30-60 volts. h. 37% solution of formaldehyde per 100 in. including isolated resin in the presence of 1-3 c. h caustic soda. In the case of direct treatment of the roots in 100. including crushed root take 20-40. h, 37% formalin solution. REF. editor M. M. Akishin
работку провод т в присутствии 1 - 3 в. ч. едкого натра.the work is done in the presence of 1–3 in. h caustic soda.
Смесь всех этих указанных компонентов в общих случа х нагревают при перемещивании до 85- 95°, после чего продолжают перемешивать при этой температуре еще 30-60 мин. Полученную искусственную смолу нейтрализуют эквивалентным количеством серной, сол ной или молочной кислоты, в случае применени минеральных кислот прессовочные порощки получают в дальнейшем суховальцевым методом; в случае же нейтрализации молочной кислотой - эмульсионным методом.A mixture of all these specified components is heated in general cases when moving up to 85-95 °, after which they are further stirred at this temperature for another 30-60 minutes. The artificial resin obtained is neutralized with an equivalent amount of sulfuric, hydrochloric, or lactic acid; in the case of the use of mineral acids, compression flakes are obtained further by the dry-spacing method; in the case of neutralization with lactic acid - the emulsion method.
Приготовление прессовочных порошков и прессование изделий производитс известными методами при температуре 140-200° и удельном давлении 200-300 кг/см.Предмет изобретени The preparation of pressing powders and the pressing of products is carried out by known methods at a temperature of 140-200 ° and a specific pressure of 200-300 kg / cm.
Способ приготовлени пластических масс на основе искусственных смол, отличающийс тем, что формальдегид конденсируют с мелко измельченными корн ми растени щаир (Ferula Schair) или со смолой, выделенной из корней этого растени известными приемами.A method for the preparation of plastic resins based on artificial resins, characterized in that formaldehyde is condensed with finely chopped shchair root plants (Ferula Schair) or with a resin isolated from the roots of this plant using known techniques.
