非硅系PU革离型纸原纸的开发

在实验室条件下,针对非硅系PU革离型纸最重要的三个性能:强度、耐热性和纸膜结合强度,对增强剂的用量进行了三因素四水平的正交实验,对耐热剂某金属氧化物的用量进行了优化,并探讨了纸膜结合强度对原纸的平滑度和孔隙率的特殊要求。结果表明:增强剂的最佳添加量为CS用量为1.5%,PAE用量为0.8%,CPAM用量为0.06%,耐热剂某金属氧化物的最佳用量为6%;原纸的平滑度相对于孔隙率而言,对纸膜结合强度的影响更显著。

Development of base paper for non-silicon release paper for PU artificial leather

The experiments to base paper for non-silicon release paper for PU artificial leather were carried out tbr improving the three most important properties under lab conditions： strength, heat resistance and adhesive strength between coat layer and base paper. The optimum dosage of strengthening agent were obtained via orthogonal experiments. and the dosage of the heat resistance agent was optimized, the influence of smoothness and porosity of base release paper on adhesive strength between coat layer and base paper were investigated as well. The results show that the optimum conditions for strength and heat resistance of the base release paper are as follows： dosage of cationic starch （CS） 1.5%, dosage of polyaminopolyamine epichtorhydrin （PAE） 0.8%, dosage of cationic polyacrylamide （CPAM） 0.06%, dosage of heat-resistant agent 6%. Smoothness of base release paper has a bigger impact on adhesive strength of coat layer and base paper than porosity of base release paper.
