摘要
为了改善聚醋酸乙烯乳液胶粘剂的耐水性、耐热性、耐寒性和乳液稳定性差,蠕变性大及粘接强度低的缺点。本实验通过采用多苯基多异氰酸酯(PAPI)及羧基丁苯胶乳对聚醋酸乙烯乳液改性,配置出一种双组分改性聚醋酸乙烯乳液,该改性聚醋酸乙烯乳液在室温(25℃)下的固化时间约为1.5h。与传统的聚醋酸乙烯酯白乳胶相比较,具有抗冻性好、贮存稳定、成本低、性能好以及用途更广等优点。可用于制造高档家具。
To improve polyvinylacetate (PVAc) emulsion adhesive the failing of bad water - resistance, heat - resistance , freeze - resistance and emulsion stability, large creep and low bonding strength. In this paper, a kind of two component adhesive was prepared by modifying PVAc emulsion with polyaryl polyisocyanate and carboxylic styrene butadiene latex. The adhesive curing time is 1.5 hour at room temperature(25℃) . By comparing with the traditional white milky glue, the economical and technicaltargets of this PVAc emulsion are better. The PVAc emulsion can meet the need of high - grade furniture manufacture.
