技术领域
本发明涉及造纸领域，尤其涉及一种低收缩耐磨装饰原纸及其制备方法。
背景技术
装饰原纸是一种以优质木浆和钛白粉等填料为主要原料经特殊工艺加工而 成的工业特种用纸，一般在高温条件下压贴在板材表面，用于人造板材的表面 装饰。经装饰纸饰面后的人造板，不仅耐磨、耐热、耐香烟灼烧、耐污染，而 且表面花色丰富，美观时尚，视觉效果好。装饰原纸的主要技术要求是印刷适 性，即良好的油墨转移吸收性，有一定的平滑度、纸质压缩性和柔软性好，同 时要求遮盖性；其次则要求装饰原纸具有良好的吸收性，经浸渍能吸收三聚氰胺 树脂。装饰原纸的质量直接决定着人造板表面修饰质量和人造板产品的品质， 目前装饰原纸耐磨性差，易收缩变形，导致人造板表面修饰质量和人造板产品 的品质降低。
为解决上述问题，本申请中提出一种低收缩耐磨装饰原纸及其制备方法。
