摘　　要：以三聚氰胺、双氰胺、戊二醛为主要原料,合成了一种无甲醛氨基树脂复鞣剂(GDAR)。研究了GDAR的复鞣性能,并与商品氨基树脂(FAR)进行了应用性能对比,结果表明:GDAR可提高成品革的丰满性、粒面紧实度及抗撕裂力。GDAR产品中及其复鞣的成革中均无游离甲醛检出,具有明显的环保优势。扫描电镜结果表明,GDAR可均匀地填充于胶原纤维之间,从而赋予成革均匀一致的手感。A novel formaldehyde -free amino resin retanning agent （GDAR）was synthesized with melamine, dicyandiamide and glutaraldehyde as raw materials. The retanning properties of GDAR were also studied using commercial amino resin（FAR） as comparison. The results show that GDAR can enhance fullness, grain tightness and tearing strength of leather. Additionally, there is no formaldehyde in both GDAR and retanned leather by GDAR. The SEM results indicate that the GDAR can dispersion and penetration in collagen fibers evenly,which gives uniform and even hand feeling for the retanned leather.
