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, deltamentrin, 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 untreated 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. Deltamentrin 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 deltamethrin 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 properties met the national standard.
