阳离子分散松香胶/AKD乳液/壳聚糖联合提高麻浆与烟梗浆配抄滤嘴棒用纸的疏水疏油性能OA
Improvement of Hydrophobic and Oleophobic Properties of Filter Rod Paper Made by Hemp Pulp and Tobacco Stalk Pulp Based on the Addition of Cationic Dispersion Rosin Size/AKD Emulsion/Chitosan
以麻浆和烟梗浆为原料,抄造滤嘴棒用纸.通过浆内添加施胶剂[阳离子分散松香胶和烷基烯酮二聚体(AKD)乳液]和表面涂布壳聚糖的方法,提高滤嘴棒用纸的疏水疏油性能.探究施胶剂添加量和壳聚糖涂布量对滤嘴棒用纸防水性能、防油等级和物理性能的影响.研究结果表明:当浆内阳离子分散松香胶和 AKD 乳液添加量均为2%(相对绝干浆)时,滤嘴棒用纸的接触角为 128.8°,60 s 时滤嘴棒用纸的可勃值为 24.30 g/m2;当壳聚糖涂布量为20 g/m2时,滤嘴棒用纸的防油等级为 12级.
The filter rod paper was made by hemp pulp and tobacco stalk pulp in our present study.The hydrophobic and oleophobic properties of the filter rod paper were improved by adding sizing agent(cationic dispersion rosin size and al-kylenone dimer[AKD]emulsion)and coating chitosan on the surface.The effects of sizing agent additions and chitosan coating weights on the water repellency,oil repellency and physical properties of the filter rod paper were further investi-gated.The study showed that when both cationic dispersion rosin size and AKD emulsion were added by 2%(based on oven dry pulp),the contact angle of the composites reached at 128.8° and the Cobb 60 s value of the composites was 24.30 g/m2.The oil resistance grade of the composite was 12 when the coating weights was at 20 g/m2.
