Damp-proof stain-resistant corrugating medium and preparation method thereof

The invention relates to the technical field of corrugated paper preparation, in particular to moisture-proof and stain-resistant corrugated base paper and a preparation method thereof. The waste paper pulp, the aminated carboxymethyl cellulose, the calcium silicate, the diatomite and the polyvinyl alcohol are used for preparing the corrugating base paper, then the hydrophobic coating containing the modified polyurethane emulsion and the modified silicon dioxide is coated on the corrugating base paper, and the hexamethyldisilazane is used for modifying the silicon dioxide, so that the hydrophobicity of the silicon dioxide is enhanced. Therefore, the corrugating base paper has excellent moisture resistance and stain resistance. 本发明涉及瓦楞纸制备技术领域，具体为一种防潮耐污的瓦楞原纸及其制备方法。本发明使用废纸浆、氨基化羧甲基纤维素、硅酸钙、硅藻土、聚乙烯醇制备瓦楞原纸，然后在瓦楞原纸上涂覆含有改性聚氨酯乳液、改性二氧化硅的疏水涂层，使用六甲基二硅胺对二氧化硅进行改性，增强了二氧化硅的疏水性。使得瓦楞原纸具备优异的防潮耐污性。
