Abstract
Изобретение относитс к области целлюлозно-бумажной промышленности и позвол ет улучшить качество картона за счет повьппени удлинени при разрыве и сопротивлени излому при сохранении остальных показателей. К макулатурной массе добавл ют дивинил- метилметакрилатный латекс, перемешивают и ввод т в качестве полимерной добавки полигексаметиленгуанидин The invention relates to the field of pulp and paper industry and improves the quality of cardboard by increasing the elongation at break and resistance to fracture while maintaining the other indicators. Divinyl methylmethacrylate latex is added to the waste mass, mixed and polyhexamethyleneguanidine is added as a polymer additive.
Description
Изобретение относитс к целлюлозно-бумажной промьштенности, в частности к композици м составов дл изготовлени картона, и может быть использовано в производстве картона.The invention relates to the pulp and paper industry, in particular to compositions of compositions for the manufacture of cardboard, and can be used in the manufacture of cardboard.
Целью изобретени вл етс улучшение качества картона за счёт повьппе- ни удлинени при разрьгое и сопротивлени излому при сохранении остальных показателей.The aim of the invention is to improve the quality of the paperboard by increasing the elongation with rarefaction and resistance to fracture while maintaining the other indicators.
Состав дл изготовлени картона содержит макулатуру, дивинилметил- метакрилатньй латекс и полимерную добавку, в качестве последней содержит полигексаметиленгуанидин (ПГМГ) при следуюгцем соотношении компонентов , мас.%:Composition for making cardboard contains waste paper, divinylmethyl methacrylate latex and polymer additive, as the latter contains polyhexamethyleneguanidine (PGMG) at the next ratio of components, wt.%:

П р и м е р 2. Массу готов т ана- логично примеру 1, только вместо ППС ввод т ПГМГ в виде 0,1%-ного водного раствора. Остальные примеры, вьтол- ненные аналогично примерам 1 и 2, сведены в таблицу,PRI mme R 2. The mass is prepared similarly to Example 1, but instead of PPS, PHMG is introduced in the form of a 0.1% aqueous solution. The remaining examples, similar to examples 1 and 2, are tabulated.
Из таблицы следует, что удлинение при разрыве картона, изготовленного из предлагаемого состава, по сравнению с известным увеличилось на 35- 50%, сопротивление излому .- в 2-3 ра- за. При снижении расхода ПГМГ резко падает впитываемость при одностороннем смачивании картона, изготовленного из предлагаемого состава, С увеличением расхода ПГМГ впитываемость при одностороннем смачивании у картона , изготовленного из предлагаемого состава, ухудшаетс .It follows from the table that the elongation at break of cardboard made from the proposed composition, in comparison with the known, increased by 35-50%, the fracture resistance .- 2-3 times. With a decrease in the consumption of PHMG, the absorbability drops dramatically when one-sided wetting of the cardboard made from the proposed composition drops.
