摘要

本文重点研究了不锈钢纤维的施加比率对钢/木纤维复合中纤板性能和电磁屏蔽效能的影响。结果表明,不锈钢纤维的施加比率对复合中纤板的力学性能影响显著;在钢/木混合纤维中施加一定量的异氰酸酯胶可显著改善中纤板的胶合性能并达到国标要求。不锈钢纤维的施加比率及其在中纤板中的复合位置对电磁屏蔽效能影响显著, 当钢/木纤维混合比率为3∶1并复合在中纤板的双侧表面时,其电磁屏蔽效能可达55dB以上。

Abstract

The ratio of steel fiber and wood fiber in a composite MDF, which could be used as electromagnetic shielding material, was studied in this paper. The results showed that steel fiber mixed with wood fiber can cause a negative effect on bonding strength of the composite MDF board, but a certain amount of PMDI resin applied on the steel fiber can significantly improve the board properties. The steel/wood fiber ratio and the mixed fiber position in the MDF also showed an effect on the electromagnetic shielding property of the board. The composite MDF had good electromagnetic shielding effectiveness with values beyond 55 dB at a steel/wood fiber ratio of 3∶1 and the steel/wood composites on the top and bottom surfaces of the MDF.
