Description
Дл проклейки бумаги и картона примен ют клеи на основе омыленной канифоли. Различные услови проклейки требуют приготовлени различных видов канифольного кле .Adhesives based on saponified rosin are used for sizing paper and paperboard. Different sizing conditions require the preparation of various types of rosin glue.
Предложен способ, позвол ющий получать канифольный клей, пригодный дл проклейки бумажной массы в различных услови х.A method has been proposed which makes it possible to produce a rosin glue suitable for sizing paper pulp under various conditions.
Способ заключаетс в том, что к канифоли добавл ют малеопимаровую кислоту, смесь омыл ют, пли раздельно омыл ют канифоль и малеопимаровую кислоту, затем их смешивают .The method consists in the addition of maleopimaric acid to the rosin, the mixture is saponified, or the rosin and maleopimaric acid are separately saponified, then they are mixed.
Канифоль и малеопимаровую кислоту берут в количестве 75 и 25 вес. ч.Rosin and maleopimaric acid are taken in the amount of 75 and 25 weight. h
Канифольно-малеопимаровый клей значительно повышает степень проклейки (до 200/0), а также влагостойкость проклеенной бумаги.Rosin-maleopimarovy glue significantly increases the degree of sizing (up to 200/0), as well as moisture resistance of glued paper.
Предмет изобретени Subject invention
Способ получени кле дл проклейки бумаги и картона на основе омыленной канифоли , отличающийс тем, что, с целью повышени качества кле , к канифоли добавл ют малеопимаровую кислоту.A method for producing paper and cardboard sizing based on saponified rosin, characterized in that, in order to improve the quality of the glue, maleopimaric acid is added to the rosin.
