摘要

用丙烯酸丁酯（BA）对白乳胶进行共聚改性,对合成条件进行了探讨,确定了相对较佳的合成工艺,合成出一种价格合理、性能优良的木材用胶黏剂—聚醋酸乙烯酯乳液（PVAc）。通过对产物的各种性能的测试比较,及对其应用性能测试,结果表明,其粘接、防冻、耐水性能良好。

Abstract

In this paper,white emulsion was modified by butyl acrylate,and the conditions for synthesizing a new wood adhesive-PVAc were determined.The performances,including viscosity,solid content,mechanical stability,and pH were tested.The performance for application,such as winter resistance,freeze thaw stability,and water resistance were tested and compared with that of the commonly used white emulsion.The results showed the new wood adhesive-PVAc had good performance and no pollution.
