Water and Oil Resistance of Special Paperboard for Petroleum Packaging

The influence of different coating formulas and times on the water and oil resistance of paperboard was studied. The water and oil resistance of paperboard coated with a modified butadiene-styrene copolymer latex and fluorinated anion grease-proof agent was better than that coated with modified butadiene-styrene copolymer latex,where the modified butadiene-styrene copolymer latex was used as the pre-coating substrate and the F1516 fluorinated grease-proof agent was used as the top coating material. By coating modified butadiene-styrene copolymer latex with 30% solid content and F1516 fluorinated grease-proof agent with 24% solid content,the oil resistance of paperboard could reach anti-oil grade 12 and the water resistance could increased by98. 64%( compared with the base paperboard without any coating treatment).

二次涂布对石油包装特种纸板性能的影响

研究了以不同固含量的A号涂布剂为底涂原料,以23%,固含量的阳离子聚丙烯酸酯作为面涂原料对牛皮卡纸进行二次涂布,观察其对石油包装特种纸板抗水抗油性能及强度性能的影响.结果表明:随着A涂布剂固含量的增加,纸板的抗水性能和抗油性能逐渐增加;纸板的强度性能除横向抗张强度无明显变化、纵向撕裂度有所减小外,其他强度性能都逐渐增加.当A号涂布剂的固含量为30%,时,石油包装特种纸板的各项性能较好,可以满足石油包装纸板的性能要求.
