摘 要
随着人们环境保护意识的不断增强，开发绿色环保型产品已成为各行各业发展的主流方向。聚醋酸乙烯酯乳液俗称白乳胶，是应用最广的胶粘剂之一，由于它为水基胶粘剂，具有其他胶粘剂不可比拟的无毒、无腐蚀和优良的环保性能，并且原料来源广泛，成本较低，在胶粘剂中所占比例也越来越大，但白乳胶也存在一些性能上的不足，如耐水性，耐热性，抗蠕变性，耐寒性及耐机械稳定性等均较差。因此，需要对聚醋酸乙烯酯乳液的合成工艺进行研究，确定最佳红岩精彩片段摘抄>日童工艺条件，或对聚醋酸乙烯酯乳液进行改性，以提高其各方面的性能，也扩大其应用领域。
本文重点阐述了聚醋酸乙烯酯乳液合成原理，最佳合成工艺及改性研究。在其应用上，除普遍适用于木材的粘合以外，聚醋酸乙烯酯类胶粘剂正渐渐的被应用于建筑等很多行业，并且，本文针对目前研究较少的胶类降解的研究给予系统盘转移简单的分析。

Along with the enhancement of people’s environment protection consciousness, the green environment protection product has become the mainstream. The polyvinyl acetate emulsion is named the white emulsion, which is one of the most widely ud adhesives. Becau it is water ba adhesive, comparing with other adhesives it is non-toxic, non-corrosion and fine environment protection performance. The raw material of polyvinyl acetate emulsion is widespread, costs lower, so its proportion in the adhesive is more and more.But the white emulsion also has the insufficiency in some performance, like the water resistance, the thermal stability, the anticreep, the resistance to cold and bears mechanical stability are all infirmness. Therefore, we need to conduct the rearch to the polyvinyl acetate emulsion synthesis craft, and find the best craft condition, or carry on the modification to the polyvinyl acetate emulsion. We can enhance its various performance through the craft improvement and the modification of the performance, also expand its application.
教师论文This article elaborates the polyvinyl acetate emulsion synthesis principle, best synthesis craft and modified rearch. In its application, besides it is generally ud for the lumber agglutination, the polyvinyl acetate adhesive is gradually applied to the construction and so on. In this article, some simple analysis of degradation is also mentioned .
