Abstract

리그노셀룰로오스 함유 물질의 판지와 그러한 판지 제조방법. 물질은 입자 또는 섬유로 붕괴되고, 건조전 또는 후에 건조되고, 접착되며 매트를 형성하고 마침내 완성된 판지에 열압에 의해 건조된다. 본 발명에 따라, 증가된 결합반응성이 친수성기의 도입에 의해 수득되고 리그닌의 연화온도가 저하되도록 하기 위해 리그닌은 최종건조 이전에 입자 또는 섬유의 표면층에 적어도 화학적으로 변경된다. 그것에 의하여 판지에 리그노셀룰로오스 물질이 유기적으로 결합된 황이 물질의 원래의 황의 합량을 초과하나 0.4 보다 더 낮게 되도록 부분적으로 술폰화된다.Paperboard of lignocellulosic containing material and method for making such paperboard. The material disintegrates into particles or fibers, dried before or after drying, adhered to form a mat and finally dried by thermal pressure to the finished cardboard. According to the invention, the lignin is at least chemically altered in the surface layer of the particles or fibers prior to final drying so that increased binding reactivity is obtained by the introduction of hydrophilic groups and the softening temperature of the lignin is lowered. This is partially sulfonated such that the organically bound sulfur of the lignocellulosic material on the cardboard exceeds the sum of the original sulfur of the material but is lower than 0.4.
