摘要
目的实现包装人造板的防白蚁功能。方法采用联苯菊酯、溴氰菊酯和高效氯氰菊酯为防白蚁剂,制备具有防白蚁功能的三聚氰胺甲醛树脂胶(MF)速生杨胶合板。研究防白蚁剂对MF胶黏剂的初粘度和胶合强度,白蚁作用方式,胶合板的防白蚁性能和力学性能等的影响。结果所用的防白蚁剂在MF中分散性良好,无分层现象。防白蚁剂对胶合强度有不良影响,溴氰菊酯和高效氯氰菊酯对弹性模量、静曲强度产生不良影响,但其浓度对弹性模量、静曲强度无显著影响。结论当联苯菊酯占MF的质量分数为1.25%,或溴氰菊酯占MF的质量分数为5%,或高效溴氰菊酯占MF的质量分数为2.2%时,胶合板的防白蚁性能最佳,白蚁死亡率达到100%,而且其主要力学性能指标均达到国家标准要求。
Objective To study the termite-resisting function of packing wood-based panel. Methods Mothproof plywood was manufactured using poplar veneer and melamine formaldehyde resin (MF) which were previously mixed with erther bifentrin, dehamentrin, or beta-cypermethrin. In this article, we tested the viscosity of melamine formaldehyde resin and the mechanical properties of mothproof plywood. This study evaluated the ability of termites to decompose pest control-treated or un treated plywood by termite mortality rate. Results The results suggested that the anti-termite agent was uniformly dispersed in the MF resin, and was not stratified. The bonding strength was declined. Dehamentrin and beta-cypermethrin had adverse effects on MOE and MOR, but its concentration had no significant effect on MOE and MOR. Conclusion When the ratio of bifenthrin and MF was 1.25% , or ratio of dehamethrin and MF was 5% , or ratio of efficient deltamethrin and MF was 2.2% , the plywood had the best anti-termite performance, the termite mortality rate reached 100%, and the main mechanical proper- ties met the national standard.
