卡纸涂层对EB固化直接真空镀铝工艺的影响

通过改变卡纸涂布量和涂层中瓷土与碳酸钙的比例，研究了卡纸涂层对电子束固化直接真空镀铝工艺的影响。结果表明，随卡纸涂料量提高，表征涂层开放程度的油墨吸收性也随之提高，但卡纸的耐折性能则下降，电子束（EB）固化预涂料涂布量也随之增大；卡纸涂层材料中颜料的组成对卡纸性能及EB固化涂料预涂量有影响，随着颜料中瓷土含量降低，碳酸钙含量提高，涂层的开放程度提高，纸张光泽度下降。

Influence of Coating Composition of Paperboard on Electron Beam Curing and Vacuum Aluminizing Process

The influence of coating composition of paperboard on electron beam curing and vacuum aluminizing process was studied by changing the pigment weight and its composition （the ratio of clay to calci- um carbonate）. The results show that with the increasing of the coating weight on paperboard, K＆N （the parameter for ink absorbency of paper board, which characterizes the openness of the paper coatings） in- creases, the folding performance are reduced and the coating weight for electron beam curing increases. The pre-eoated weight of electron beam curing coating was also depended on the ratio of clay to calcium carbonate. With decreasing the clay content and increasing the calcium carbonate content, the openness of the coatings was increased and the coating gloss was reduced.
