| 摘 要： | 以镍粉、石墨粉、不锈钢纤维和铜纤维作为导电单元,脲醛树脂为胶黏剂,制备3层落叶松胶合板,研究不同导电单元和涂胶量对板材电磁屏蔽效能(ESE)及胶合强度的影响.结果表明,纯镍粉填充的胶合板的ESE几乎为零;后3种导电单元填充的胶合板ESE分别达到5～10 dB,17～21 dB和6～17 dB;试板的胶合强度除不锈钢纤维添加量为80 g/m2时低于国家标准外,其余条件下均达到或超过国家相关标准要求.

| Abstract: | Some electric materials, such as Ni powder, graphite powder, stainless steel fiber and copper fiber,were added to urea-formaldehyde resin to manufacture plywood that would act as an electromagnetic shield. The influence of different electro-conductive elements and adhesive spread on shielding and bonding strength of Larix plywood was investigated. The results showed that shielding from plywood with the addition of pure Ni powder was nearly zero and that the addition of graphite powder, stainless steel fiber and copper fiber were 5-10 dB, 17-21 dB and 6-17 dB respectively. Except the bonding strength was 0.46 MPa, which was lower than the national standard when the spread of stainless steel fiber was 80 g/m^2, under other conditions, the bonding strength of the plywood could meet or exceed the requirements of the related national standard. |
