Abstract In order to decrease the usage of formaldehyde and petroleum-derived raw materials, there has been a lot of interest in using protein-based wood adhesives as more eco-friendly and less hazardous alternatives. Fish proteins can be extracted from fish and are known to have good adhesive properties. In this work, we extracted the protein from catfish skin and characterized its effectiveness as a wood adhesive. Upon analysis, this protein from catfish skin (a byproduct of catfish processing) performed well as an adhesive, with similar (or slightly better) dry adhesive strength relative to cottonseed protein isolate. The blend of catfish protein and cottonseed protein displayed about the same dry adhesive strength when compared to catfish protein alone. The hot water resistance of catfish protein and cottonseed protein was comparable, but the 1:1 blend exhibited improved performance than the two proteins by themselves. These results suggest that the protein from catfish skin may be a suitable material for wood adhesive applications.

鲶鱼蛋白作为木材粘合剂的制备与评价

摘要 为了减少甲醛和石油衍生原材料的使用，人们对使用蛋白质基木材粘合剂作为更环保、危害更小的替代品产生了浓厚的兴趣。鱼蛋白可以从鱼中提取，并且已知具有良好的粘附特性。在这项工作中，我们从鲶鱼皮中提取了蛋白质，并表征了其作为木材粘合剂的有效性。经分析，这种来自鲶鱼皮（鲶鱼加工的副产品）的蛋白质作为粘合剂表现良好，相对于棉籽分离蛋白具有相似（或稍好）的干粘合强度。与单独的鲶鱼蛋白相比，鲶鱼蛋白和棉籽蛋白的混合物表现出大致相同的干粘合强度。鲶鱼蛋白和棉籽蛋白的耐热水性相当，但 1:1 混合物表现出比两种蛋白质本身更高的性能。这些结果表明，鲶鱼皮中的蛋白质可能是木材粘合剂应用的合适材料。
