涂布液体石蜡对植物纤维基地膜纸的影响
Effect of Coated Liquid Paraffin on Agricultural Cellulose Film
摘要
Abstract
In our present study,bleached softwood pulp was used as fiber raw material with a beating degree of 89°SR,and the addition amount of additives polyamide polyamine epichlorohydrin(PAE),alkyl ketene dimer(AKD),and cationic starch,2.0%,0.4%and 1.0%(based on dry pulp quality),respectively,to prepare(40±2)g/m2 coated base paper.Then the plant fiber base film paper was prepared by coating liquid paraffin on the surface to improve the light transmittance,water resistance and reduce air permeability of the film paper.The results showed that the optimal coating amount of liquid paraffin was 7 g/m2,the quantitative amount was 48.16 g/m2,the dry tensile index was 70.91 N·m/g,the tear index was 5.99 mN·m2/g,and the break resistance index was 5.12 kPa·m2/g.The transmittance was 82.82%and the air permeability was 0.0030µm/Pa·s.The Cobb value after 300 s was 15.8 g/m2.After soaking in water for 12 h,the wet strength of the coated sample was increased by 14.34%than that of the uncoated sample.关键词
