摘要
对纺织用防油剂在防水纸板中的应用性能进行了研究。通过生产实践可以确定纺织用防油剂可以满足防水纸板的使用要求。同时,可以采用防油剂与生产水共混进行浸渍加工,实现纸板的防油要求,要求纸板在雨季使用时,纸板表面的雨水能够顺势滑落到地面,雨水不会向纸张另一面渗透。浆料打浆度、防油剂用量等均会对纸张防油性产生较为明显的影响,较为有利的工艺控制为牛卡45%、办公废纸用量55%,纸浆料打浆度约25°SR,PAE湿强剂50kg/t纸,干强剂用量22kg/t,AKD用量2kg/t纸,防油纸板中氟含量不低于3.5kg/t纸,可以满足防水纸板的性能要求。
The application of textile oil repellent in grease proof paper was studied in this article.Through production practice,it can be determined that the oil repellent can meet the requirements of waterproof paperboard.At the same time,the oil proofing agent and production water can be blended for impregnation process to achieve the oil proofing requirements of the paperboard.When the paperboard is used in the rainy season,the rainwater on the surface of the paperboard can slide to the ground,and the rainwater will not penetrate into the other side of the paper.The pulp beating degree and the amount of oil repellent have obvious inf luence on the oil repellency of paper.The more favorable process control is the kraft 45%,the amount of office waste paper 55%,the paper pulp beating degree about 25°SR,the PAE wet strength agent 50 kg/t paper,the amount of dry strength agent 22 kg/t,the AKD amount 2 kg/t paper,and the fluorine content of waterproof board is not less than 3.5 kg/t paper,which can meet the performance requirements of waterproof board.
