酮肼交联聚丙烯酸酯纸张表面 施胶剂的制备及性能研究
Study of preparation and properties of ketone-hydrazide crosslinking polyacrylate paper sizing agents
摘要
Abstract
A series of polyacrylate microemulsion were prepared with anionic acetoacetoxyeth-yl methacrylate (AAEM ) and adipic acid dihydrazide (ADH ) crosslinking by Soap-free e-mulsion polymerization ,which can be used to enhance the paper′s surface performance as a surface sizing agents .The effect of the amount of AAEM on emulsion and sizing performance of the paper were systematically studied .The results indicated when the molar percentage of AAEM and ADH were 5 .28％ and 3 .24％ ,respectively ,the performance of paper surface siz-ing has improved significantly compared to starch sizing ,wet and dry strength increased by 47 .6％ ,247 .3％ ,folding endurance increased by 93 .3％ ,and water contact angle also in-creased significantly .In addition ,NMR and FT-IR results showed that :double bond mono-mer was successfully bonded to the acrylate polymer ,and the appearance of hydrazone con-firmed the crosslinking reaction of ketone with hydrazine occurs .SEM showed that ,the e-mulsion can crosslinked a dense network structure in the surface and inside the paper to im-prove the bonding strength between the fibers .Atomic force microscopy showed that :the surface of paper is smooth and showed good hydrophobicity after sizing .关键词
