Изобретение относитс к целлюлозно-бумажной промышленности, а именно к композици м бумажной массы дл производства клееных видов бумаги и картона с повышенной прочностью во влажном состо нии, и может быть использовано в бумажном и картонном производстве,The invention relates to the pulp and paper industry, namely, paper pulp compositions for the production of glued paper and paperboard with increased wet strength, and can be used in paper and paperboard production,
Целью изобретени вл етс улучшение качества массы дл повышени прочности бумаги во влажном состо нии , снижени ее впитываемости при одностороннем смачивании и сохранении прочности в сухом состо нии,The aim of the invention is to improve the quality of the mass in order to increase the strength of the paper in the wet state, reduce its absorbency while one-sided wetting and preserve the strength in the dry state,
Пример, К небеленой сульфатной целлюлозе в виде водной суспензии добавл ют 2 мас,% канифольного кле и перемешивают 120 с, затем добавл ют 0,2 мас.% продукта поликонденсации эпихлоргидрина и аммиака (ПРПЭА) в виде водного раствора и премешивают в течение 300 с,Example: To the unbleached sulphate pulp, in the form of an aqueous suspension, add 2% by weight of rosin glue and mix for 120 seconds, then add 0.2% by weight of the polycondensation product of epichlorohydrin and ammonia (PREPA) as an aqueous solution and mix for 300 seconds. ,
ПРПЭА представл ет собой соединение желто-коричневого цвета общей формулыPRPEA is a yellow-brown compound of the general formula

с молекул рной массой 2-2,5 тыс, у.е. При синтезе полиэлектролита эпихлор- гидрин и аммиак берут в мольном соотношении 1:0,43,with a molecular weight of 2-2.5 thousand, cu In the synthesis of polyelectrolyte, epichlorohydrin and ammonia are taken in a molar ratio of 1: 0.43,
Из полученной бумажной массы на листоотливном аппарате ЦБТФ изготавливают опьп-ные образцы массой 1м, 70 г, которые испытывают в соответствии с требовани ми ГОСТ 13525.1-78, ГОСТ 12607-67, ГОСТ 13525,7-79, ГОСТ 9582-75,From the obtained paper pulp on a TsBTF sheet-making machine, samples of 1 m, 70 g are produced, which are tested in accordance with the requirements of GOST 13525.1-78, GOST 12607-67, GOST 13525,7-79, GOST 9582-75,
Составы бумажных масс и показатели бумаг на их основа сведены в таблице , The composition of the paper pulp and paper indicators on their basis are summarized in the table
Как видно из таблицы, использование предлагаемой бумажной массы позвол ет увеличить прочность бумаги во влажном состо нии в 1,7-2,2 раза и снизить впитываемость бумаги приAs can be seen from the table, the use of the proposed paper pulp allows one to increase the strength of paper in the wet state by 1.7-2.2 times and reduce the absorbency of paper when
одностороннем смачивании в 1,2-3,4 раза при сохранении прочности бумажного листа в сухом-состо нии.one-sided wetting 1.2-3.4 times while maintaining the strength of the paper sheet in the dry state.
