摘要
以丙烯酸为原料,制备了聚丙烯酸钠吸附树脂。建立了一种对其粘附性能的测定方法并测定了其粘附性能,讨论了该树脂粘附性能的影响因素。结果表明:当中和度为70%,引发剂用量为单体质量的0.1%,交联剂用量为单体质量的0.01%,吸水倍率为2倍时,材料有最佳粘附性能。
A poly （sodium acrylate） absorption resin was systhesized from acrylic acid （AA）. The adhesion force in swollen states were measured using a new teehnique by a probe contaet. Then the influencing factor of the resin＇s adhesion properties was discussed. The results indicated that the best preparation eraft was as follow：the neutralization value of the acrylic acid is 80 % ,the initiator amount used was the lumpymass 0.1% ,the crosslinking agent amount used was the reactant lumpymass 0.01%. And the adhesion force reached maximum value when the water absorbency was 2 g/g.
