聚醋酸乙烯酯共聚胶液的改性研究

聚醋酸乙烯酯作为常用的胶粘剂之一,有明显的优点,但随着环保和绿色生活的要求,其有毒和耐水性等缺陷影响了其更好发展.本研究利用醋酸乙烯酯与其它烯类单体的共聚,制备出了无毒、快干、胶接强度高、耐水性好的高性能聚醋酸乙烯酯共聚改性胶液,并对其相关影响因素及工艺条件的确定进行了讨论.

Study on PVAc Adhesive through Modified Copolymerization

Polyvinyl acetate is one of communal adhesives, having good (overt) advantage. However, with the demand of protecting environment and green life, some limitation such as high toxicity and poor water resistance has tamper with the development of polyvinyl acetate. In this paper, a new type of adhesive was synthesized by copolymerization of VAc and other modified vinyl monomers. The influencing factors and technical conditions were discussed in detail. The properties of adhesive such as avirulence, quick-drying property, high bonding strength and good water resistance were also introduced briefly.
