METHOD OF PRODUCING GLUING ENHANCER

FIELD: paper.SUBSTANCE: invention relates to pulp and paper industry， specifically to production of reinforcing additive and production of hydrophobic paper containing reinforcing additive. Method of producing the reinforcing gluing additive involves the following stages: I) combining lignin-containing oil and aqueous solution of gelated cationic polysaccharide and optionally water， II) mixing the lignin/polysaccharide mixture at temperature of 40–100??°C， preferably 90–95??°C， until mixture changes colour from grey-white to brown. Method of producing hydrophobic paper involves a step of adding a reinforcing gluing additive and a hydrophobisating agent to a suspension of lignocellulosic pulp on the wet side of the paper making process.EFFECT: invention enables to obtain a reinforcing gluing additive， reduces consumption of gluing agents when producing hydrophobic paper products， and improves properties of such paper products.16 cl， 7 tbl， 6 dwg

技术领域：本发明属于制浆造纸工业领域，具体涉及增强胶黏剂的制备以及含有该增强胶黏剂的疏水纸张的制备。
技术方案：制备增强胶黏剂的方法包括以下步骤：I）将含木质素油与凝胶化阳离子多糖的水溶液以及任选的水进行混合；II）将该木质素/多糖混合物在40~100℃（优选90~95℃）下搅拌，直至混合物颜色由灰白色变为棕褐色。制备疏水纸张的方法包括在造纸工艺的湿部（wet side of the paper making process）阶段，将增强胶黏剂和疏水化剂添加至木质纤维素纸浆悬浮液中的步骤。
有益效果：本发明可制备得到增强胶黏剂，降低疏水纸制品生产过程中胶黏剂的用量，并改善此类纸制品的性能。本申请包含16项权利要求、7个表格、6幅附图。
