摘要:以二乙醇胺、丙烯酸甲酯、三羟甲基丙烷以及环氧氯丙烷为原料,合成不同代数的端环氧基超支化聚(胺-
酯)(EHPAE)。其后,以从制革废弃物中提取的明胶为原料,不同代数的 EHPAE 分别作为交联单体进行改性,

制得一种环保型鞋用或包袋用胶粘剂。采用 FTIR、 HNMR 和 GPC 对超支化聚合物和胶粘剂的结构及相对分子
质量分布进行表征,之后对胶粘剂的粘结性能进行测定,结果表明:EHPAE-Ⅲ较其余两者的改性效果更为明显,
当 EHPAE-Ⅲ用量为明胶质量的 30%时,改性后胶粘剂的固含量由 11.42%提高到了 30.33%,同时剪切强度为
2.216 MPa、T-剥离强度为 3.375 N/mm、水接触角为 100.9°,相较于市售胶粘剂的剪切强度(1.868 MPa)、T-剥
离强度(2.864 N/mm)、水接触角(84.8°),制备得到胶粘剂的粘结性能和疏水性均更优。

Abstract: Epoxy-terminated hyperbranched poly (amine-ester) (EHPAE) samples with different generation
were prepared from diethanolamine, methyl acrylate, trimethylolpropane and epoxy chloropropane. And
then, an environmental-friendly of adhesives for footwear or bags were synthesized using gelatin extracted
from leather wastes as main material, different generation of EHPAE samples as cross-linking monomer,
respectively. The structure and relative molecular mass distribution of hyperbranched polymers and
1
adhesive were characterized by FTIR, HNMR and GPC. Moreover, the bonding performances of the
adhesive was measured. The results showed that EHPAE-III exhibited better modification effect than the
other two. When the dosage of EHPAE-Ⅲ was 30% (based on the mass of gelatin), the solid content of the
modified adhesive was increased from 11.42% to 30.33%. Meanwhile, the shear strength and T-peel
strength of the prepared adhesive were 2.216 MPa and 3.375 N/mm, respectively. The water contact angle
was 100.9°. While the commercial available adhesive showed shear strength, T-peel strength and water
contact angle of 1.868 MPa, 2.864 N/mm and 84.8°. It was found that the prepared adhesive had better
adhesive properties and hydrophobicity than the commercial available adhesive.
