摘要
松香胶目前仍是造纸用主要施胶剂,且已从皂化胶、强化胶、
    阴离子乳液松香胶发展到阳离子乳液松香胶—第四代产品。同时施
    胶正从酸性向中性工艺转变。我国目前仍以非木材纤维造纸为主,
    以速生丰产的桉木为原料造纸进行中性造纸是今后发展方向。本课
    题主要研究开发高效中性松香施胶剂,主要工作如下:
     (1)制备出XQ-CR阳离子松香胶、XQ-AR阴离子中性松香胶,使
    之用于桉木化机浆及其他浆料配抄优质印刷纸的中性施胶。XQ-CR
    阳离子松香胶的制备关键是阳离子松香的制备及乳化,采用的是高
    分子乳化剂。XQ-AR阴离子中性松香胶的制备关键是特效乳化剂的
    制备,其主要成分是烷基酚聚氧乙烯醚马来酸酯磺酸盐。
     (2)中性乳液松香胶必须配加相同离子性的聚丙烯酸树脂增效
    剂,这种增效剂同时具有分散和增强作用,本身亦可用于对施胶度
    要求不高的纸种的施胶处理。本课题分别研究了阴离子和阳离子聚
    丙烯酸树脂增效剂的制备条件,重点解决了松香改性及乳化、乳液
    贮存和应用工艺等问题。
     (3)制备出中性施胶用的专用留着剂。分别研究了阳离子淀粉、
    阳离子聚丙烯酰胺和阳离子聚酰胺多胺环氧氯丙烷等的应用条件,它
    们的共同特点是,具有较高的相对分子质量和较强的阳离子性,可
    在中性或弱碱性条件下显示正电性,与纤维有较强的结合作用,能
    够通过化学和物理作用产生一定的增强、留着效果。但作为中性施
    胶松香留着剂,效果以聚酰胺多胺环氧氯丙烷最佳,其在碱性条件下
    可发生自交联作用,本身亦可用于对施胶要求并不很高的纸种的施
    胶。

The rosin sizes are still the mainl~ sizing agents for paperrnaking by now. The
    
     cationic rosin sizing agents are called to be the fourth generation production from the
     soaped sizes. the fortified sizes and the anionic rosin sizes of emulsion. Simultaneously.
    
     the papermaking technology have been conversing from acidic to weekly acidic or
     neutral sizing. Also the non-wood fiber are still the mainly materials for papermaking
     in china, but using the eucalyptus wood as the new raw material for papemiaking at
     neutral conditions will be the direction of development. The present investigation relates
     to sizes for a papermaking. more specifically to an internal size which works very well
     in papermaking under weakly acidic to neutral conditions. Series emulsions of rosin
     sizes have been gotten based on lots of the literatures of at home and abroad.
    
     (1) The XQ-CR cationic rosin sizes and the XQ-AR anionic rosin sizes have been
     developed. Conventional rosin emulsion sizes consists mainly of so-called fortified
     rosins, i.e., rosins modified with ctj~-unsaturated dibasic acids, and an anionic surfactant.
     Among a few of anionic surfactants. the sulfate ester of the maleic anhydride and
     polyoxyethylene nonylphenyl ether has shown to be the effective emulsifying agent.
     The anionic and cationic rosin sizes are both used in a dispersion in the present of the
     alkyl acrylate resin emulsions which can be used as the size synergist.
    
     (2) Comprising a rosin sizing agent fortified by adding the same ionic copolymer
     emulsion of alkyl actylate with stvrene wherein the rosin and modified rosin are
     dispersed in water with the aid of an emulsifying agent and the size synergist, and paper
     sized therewith. The rosin emulsion sizing agent of the present invention have exhibited
     an distinguished sizing effect in neutral papermaking systems even when content of the
     calcium carbonate is high therein and been excellent in mechanical and storage stability
     while decreasing the production cost in addition the sizing agent presents no significant
     difficulties in its production.
    
     (3) To increase the size degree of above rosin emulsion, the polyaminoamide
     epichlorohydrin (PAE) has been used. Comprising the copolymer of cationic acrylamide
     with other hydrophilic monomer and the cationic starch, it serves very well as both a
     retention aid and a sizing agent for neutral paper because its sizing quality around the
    
    
    neuthel pH is low The high molecular weight ard the Stronger cationic ctwes are
    necesSary for attributing the excellent proPerties of retention and sizing. Not only as the
    sPecial retention agent for rosin sizes, but also the PAE can be used as the wet
    reinfOrcing agent by crossing of itself at the neutrai or basic condition.
    (4) The best conditions of preparaion and aPpiicaion of above products have been
    detendned, the sizing technology of catiohic size XQ-CR is as mis: sulfate altalniurn
    4%. XQ-CR 0.5W1 .0%,PAE 0.259M.5%. calciurn carbomate 25% with the reverse
    sining. in the summer, the disadvantaged infiuences of high temperatUr and high pH
    value tO sdrig are reduced by adding more sulfate aIurnndum and sizing agent and PAE.
    The selected technology ofedonic sizing agen XQ-AR is as this: XQ-AR 0.5Wl.0%.
    sulfate aiwtum 4%, PAE 0.259ed.5%. talcium carbomate 25% with the bet
    seq.
    (5) The measure ofsimCtUr and Properties for above ProduCts are cAned out. lt is
    helpful for studying on the chdrical interachon mechasm betwen aids and the Paper
    fiber and neutral sthe mecbosm in wet processing.
