摘　　要：为了根本上彻底解决人造板甲醛释放对人体健康的危害的问题,我们成功地研制了无醛系胶粘剂。本研究以水性异氰酸酯为交联剂,以聚乙烯醇、橡胶乳液与各助剂共混为主剂,制成了环保型人造板用无醛胶粘剂。该胶粘剂性能完全达到国家检测标准,固化快,耐水性、耐热性和耐老化性能优异,胶接强度高,无甲醛释放,对人体健康无害,生产、使用简单,易操作,完全满足现有的工艺要求。In this work,a non-formaldehyde adhesive for plywood was prepared.In this adhesive,a water-based isocyanate was used as the crosslinking agent and an elastic composite system from synthetic rubber latex,PVA and some other additives was used as the main reagent.Experimental results showed that the whole properties of this adhesive met the requirements from the national standard of plywood and decoration.As a new kind of adhesive,its weather resistance,impact resistance,strengths and adhesion properties were excellent It was easy to produce and use.
