Цель изобретени - повьшение на чальной влагопрочности бумажного полотна ,The purpose of the invention is to increase the initial moisture resistance of the paper web,
Сущность изобретени заключаетс в том, что состав дл проклейки бумаги в массе, coAepKamttfi канифоль и водорастворимое акрилсодержащее св зующее , в качестве водорастворимого акрилсодержащего св зующего содержит продукт взаимодействи щелочного гидролизата полиакрилонитрила или сополимера, включающего, мас.%: ак- рилонитрил 90-93; метилакрилат 6-8; итаконовую кислоту 1-2, с белой сажей при их массовом соотнощении со-, ответственно (3:1)-( 15:1) .The essence of the invention is that the bulk paper sizing composition, coAepKamttfi rosin and a water-soluble acrylic-containing binder, as a water-soluble acryl-containing binder, contains the product of the interaction of an alkaline polyacrylonitrile hydrolyzate or a copolymer, including wt.%: methyl acrylate 6-8; Itaconic acid 1-2, with white soot at their mass ratio is, respectively (3: 1) - (15: 1).
Применение указанного продукта в составе дл проклейки бумаги обеспечивает в совокупности с канифолью увеличение начальной влаголрочности бумажного полотна, что позвол ет снизить обрывность его в мокрой части бумагоделательной машины, а также повысить в композиции бумаги более дшевого коротковолокнистого полуфабриката .The use of this product in a paper sizing composition, in combination with rosin, increases the initial moisture content of the paper web, which makes it possible to reduce its breakage in the wet part of the papermaking machine, as well as increase the more short-fibrous semi-finished product in the paper composition.
В качестве коротковолокнистых полуфабрикатов могут быть использованы древесна масса различных способов изготовлени , макулатура, лиственна целлюлоза.As a short-fiber semi-finished product, pulp of various manufacturing methods, waste paper, hardwood pulp can be used.
Дл придани бумаге специальных свойств в бумажную массу могут включатьс специальные добавки, такие ка синтетические смолы и каучуковые ла- тексы.To impart special properties to paper, special additives such as synthetic resins and rubber resins may be included in the pulp.
Пример 1. Состав дл прокле ки бумаги в массе готов т смешением канифольного кле из модифицированно живичной канифоли (80%) и продукта взаимодействи щелочного гидролизата полиакрилонитрила с белой сажей при их соотношении 3:1 (20%), Приготовленный проклеивающий состав в количестве 2,5% от массы абсолютно сухог волокна (а.с,в) ввод т в волокнистую суспензию, содержащую небеленую хвойную целлюлозу (50%), размолотую до 35 ШР, древесную массу (60%) и каоли ( 17%) от массы а.с,в, и довод т глиноземом рН массы до 4,5, Из полученной бумажной массы получают бумагз массой 80 г/м и определ ют разрушающее усилие в сухом состо нии, впиты0Example 1. A bulk paper sizing composition is prepared by mixing rosin glue from modified gum rosin (80%) and the product of the interaction of an alkaline polyacrylonitrile hydrolyzate with white soot at a ratio of 3: 1 (20%). The sizing composition prepared is 2, 5% by weight of absolutely dry fiber (a.c, c) is introduced into a fibrous suspension containing unbleached softwood pulp (50%), ground to 35 SR, wood pulp (60%) and kaoli (17%) by weight a. c, b, and pH is adjusted to 4.5 with alumina. From the resulting paper pulp, boomers are obtained weight of 80 g / m and breaking force determined in a dry state, vpity0

При определении начальной влагопрочности получают бумажное полотно массой 45 г/м и с сухостью 35%, а затем с помощью специального шаблона раздел ют на полоски щириной 20 мм и испытывают на приборе Lorentzen Wettre при скорости раст жени 90 мм/мин. Результаты испытаний представлены в таблице.unilateral wetting, kink and ash content. When determining the initial moisture resistance, a paper web with a mass of 45 g / m and with a dryness of 35% is obtained, and then using a special template is divided into strips with a width of 20 mm and tested on a Lorentzen Wettre device at a stretching rate of 90 mm / min. The test results are presented in the table.
Пример 2. Состав дл проклейки бумаги готов т смешением канифольного кле из талловой модифицирован- ной канифоли (20%) и продукта ,взаимо- действи щелочного гидролизата сополимера , включающего, мас.%: акрило- нитрил 90-93; метилакрилат 6-8; ита- конова кислота 1-2 с белой сажей при их соотношении 15:1 (80%). Проклеивающий состав в количестве 2,5% от а.с.в. ввод т в волокнистую суспензию , содержащую беленую сульфитную хвойную (55%) и беленую сульфатную лиственную (45%) целлюлозы (степень помола 37 ll p) и каолин 17% от массы а.с.в., рН массы 4,8. Из полученной бумажной массы получают бумагу 80 г/м и испытывают по примеру 1.Example 2. A paper sizing composition was prepared by mixing rosin glue from tall modified rosin (20%) and product, reacting an alkaline hydrolyzate of a copolymer, comprising, in wt%: acrylonitrile 90-93; methyl acrylate 6-8; Itadic acid 1-2 with white soot at a ratio of 15: 1 (80%). Sizing composition in the amount of 2.5% of a.s.v. they are introduced into a fibrous suspension containing bleached softwood sulphite (55%) and bleached hardwood (45%) pulp (grinding degree 37 ll p) and kaolin 17% by weight of al.c.., pH of the mass is 4.8. From the resulting paper pulp, paper of 80 g / m is obtained and tested as in example 1.
Пример 3. Состав дл проклейки бумаги готов т смешением канифольного кле из живичной канифоли (40%) и продукта взаимодействи щелочного гидролизата сополимера с белой сажей при их соотношении 8:1 (60%), а затем ввод т в бумажную массу по примеру 2.Example 3. A paper sizing composition was prepared by mixing rosin glue from gum rosin (40%) and the reaction product of an alkaline hydrolyzate of a copolymer with white carbon black at a ratio of 8: 1 (60%), and then introduced into the pulp of Example 2.
Пример 4 (известный). Состав дл проклейки бумаги готов т смешением канифольного кле из живичной канифоли модифицированной (40%) и сополимера , содержащего, мас.%: акрило- нитрил 90-93; метилакриат 6-8; итако- нова кислота 1-2 (60%), а з&тем ввод т в бумажнзпо массу по примеру 1. Результаты испытаний представлены в таблице.Example 4 (known) The paper sizing composition is prepared by mixing rosin glue from gum rosin modified (40%) and a copolymer containing, in wt.%: Acrylonitrile 90-93; methyl acrylate 6-8; This acid is 1–2 (60%), and it is thus introduced into the paper pulp according to Example 1. The test results are presented in the table.
Сопоставительньй анализ показьгоа- ет, что предлагаемый состав дл проклейки бумаги в массе по сравнению с известный позвол ет повысить начальную влагопрочность на 16-35%,разрушающее усилие в сухом состо нии на 6-26% и проклейку на 2-3 г/м- .A comparative analysis shows that the proposed mass sizing composition compared to the known one allows an increase in the initial moisture resistance by 16-35%, a breaking force in the dry state by 6-26% and a sizing by 2-3 g / m- .
