    硅烷偶联剂对桉木单板--聚氯乙烯膜复合材料性能的影响

    Effect of silane coupling agent on mechanical properties of eucalyptus veneer/polyvinyl chloride (PVC) composites

    • 摘要: 为研究硅烷偶联剂对复合材料的性能影响,采用不同质量分数的硅烷偶联剂对桉木单板进行表面处理,然后与聚氯乙烯膜采用热压--冷压工艺制备木塑复合材料,测定复合材料的物理力学性能,并用扫描电子显微镜观察分析其界面相容机理。结果表明:当偶联剂质量分数为1%时处理效果最好,复合材料的胶合强度最高、耐水性能最好;当偶联剂质量分数为3%时,复合材料的弹性模量和静曲强度最高。单板经过硅烷偶联剂处理后,制得的复合材料的界面相容性得到改善。

       

      Abstract: By treating eucalyptus veneer with different amounts of silane coupling agent, we investigated the effect of the treatments on the physical and mechanical performance of as-obtained eucalyptus veneer/polyvinyl chloride (PVC) film composites by hot-cold pressing crafts. Interfacial compatibility of the composites was analyzed using a scanning electronic microscope (SEM). The best treating effect was observed in the composites coupled with 1% silane agent, which resulted in an increase in bonding strength and water resistance. The treatment with 3% silane coupling agent caused the increase in MOE and MOR. After the treatment with silane coupling agent, the interfacial compatibility of the veneer composites was improved.
