Description
Известен способ получени кле с использованием в качестве сырь канифоли.A known method for producing glue using rosin as a raw material.
С целью упрош,ени и удешевлени процесса , предложен способ полученн кле леносредственио пз очин1.еииой при 80-90 С живицы путем обработки ее при той же температуре малеиновым ангидридом, 25-40%ным раствором едкого натра и отгопки скипидара .In order to simplify and reduce the cost of the process, a method has been proposed for the use of resine glue at 80-90 ° C of the resin by treating it at the same temperature with maleic anhydride, 25–40% solution of caustic soda and turpentine boiling.
Пример. Очищенную нри 80-90°С от примесей живицу из отстойника подают в реактор , где при температуре 80-90°С нри ме .ханическом неремешивании ее обрабатывают малеиновым ангидридом в течение 10 - 15 мин. Необходимое количество малеинового ангидрида рассчитывают, исход из желаемого содержани малеонимарата натри в клее, но не превыша необходимое количество дл св зыва1Н1Я всей левонимаровой кислоты . Потом к смеси ностененно добавл ют едкий натр в виде 26-40Vn-iioro водного раствора дл Ызфаботки кле необходимой степени нейтра.гнзации. Затем нри темнературе массы 102-103 С начнпают отгон ть скинндар острым наром, носле отгонки скинидара в массу добавл ют воду дл получени кле пасты необходимой концентрации.Example. Purified resin 80-90 ° C from impurities resin from the settling tank is fed into the reactor, where at a temperature of 80-90 ° C, under the condition of non-mixing, it is treated with maleic anhydride for 10-15 minutes. The required amount of maleic anhydride is calculated based on the desired content of sodium maleonym in the glue, but not exceeding the required amount for bonding H1I of the entire levonimic acid. Then caustic soda is added to the mixture in the form of a 26-40Vn-iioro aqueous solution to form an adhesive with the required degree of neutralization. Then, at a temperature of 102-103 ° C, the skindar is pushed off with a sharp nap, and water is added to the mass in order to obtain the necessary concentration of adhesive paste.
Предмет изобретени Subject invention
Способ нолученн кле нз нродуктов переработки древесины, отличающийс тем, что, с целью упрощени и удешевлени нроцесса, очищенную нри 80-90°С от нримесей в отстойниках живицу последовательно обрабатывают нрн той же температуре малеиновым ангидридом, 25-40 /о-ным раствором едкого натра и отгон ют скипидар.The method for obtaining wood processing products, characterized in that, in order to simplify and reduce the cost of the process, at 80-90 ° C from the mixtures in the settling tanks, the resin is successively treated at the same temperature with maleic anhydride, 25-40 / about-caustic soda and distilled turpentine.
