【摘要】 本章论述了具有高湿粘性的硼酸化了的聚乙烯醇粘合剂.它由聚乙烯醇树脂,水溶性硼化物及具1,2羟基或1,3羟基的多元醇所组成.这种聚乙烯醇溶液的pH值较低,为新颖纸板粘合剂的生产提供了组合成份.它不但防霉、防潮、无毒,且成本低廉,对纸箱厂行业来说,是可以接受的技术改进.进一步的研究,是用高湿粘性粘合剂来减少金属表面的腐蚀,以及在使用强酸才不致凝胶的系统中,使用具高湿粘性硼酸化的聚乙烯醇溶液.更多还原

【Abstract】 This paper relates to boronized polyvinyl alcohol adhesive with a high degree of wet tack. The adhesive comprises polyvinyl alcohol resin,water soluble boron compound and,polyatomic alcohol consisting of 1, 2 polyols or 1, 3 polyols.The adhesive as mentioned above is of lower value of PH and provides for the new adhesive compositions in the production of the paperboard boxes.It is in depence of moald, moisture proof, no poison and lower cost.A futher object is to reduce the corrosion to metal surface and need not add a strong acid to prevent from the gelation of system.更多还原
