摘　　要：通过万能力学试验机实验,研究了双组分丙烯酸酯胶粘剂、EVA、YEVA、PA以及PUR等5种胶粘剂胶接木粉/聚乙烯复合材的胶接性能,以及EVA、YEVA、PA和PUR 4种热熔胶胶接木粉/聚乙烯复合材的胶接耐水性能。实验结果表明,EVA、YEVA和PUR热熔胶胶接强度要好于双组分丙烯酸酯胶粘剂,且4种热熔胶的胶接耐水性能都好于双组分丙烯酸酯胶粘剂;PA热熔胶胶接强度随浸水时间延长下降最明显。The bonding performance of the hot melt adhesives, including the two-component acrylate, EVA, YEVA（rigid EVA）, PA（polyamide） and PUR（polyurethane） based adhesives, to the wood-polyrthylene composite and the waterproofness of the bonded wood-polyethylene composite specimens with the hot melt adhesives, including EVA, YEVA, PA and PUR based adhesives is superio to that for the two-component acrylate adhesive, and the decreasing of bonding strength for PA based adhesive with increasing the soaking period on water is the clearest among EVA, YEVA, PA and PUR based adhesives.
