【摘要】：以十二烷基苯磺酸钠(SDBS)为抗静电剂,将其加入到具有核壳结构的高密度聚乙烯(HDPE)木塑复合材料中,以减小壳层HDPE的静电效应。采用超高电阻测量仪、万能力学试验机、表面接触角测试仪以及差示扫描量热仪对样品进行电学、力学、表面润湿性以及热力学分析。结果表明:未添加SDBS的核壳结构木塑复合材料的表面电阻率为10~(15)Ω;添加18%的SDBS后,木塑复合材料的表面电阻率降至10~8Ω。添加SDBS后,木塑复合材料的力学性能先上升后下降,弯曲强度较最高值下降约3.67%,弯曲模量较最高值下降约9.92%,冲击强度较最高值下降约10.20%。复合材料表面润湿性随着壳层SDBS含量的增加而降低,壳层结构HDPE基体结晶度则先降低后提高。
[Abstract]:Using sodium dodecylbenzenesulfonate (SDBS) as antistatic agent, it was added to high density polyethylene (HDPE) wood-plastic composites with core-shell structure in order to reduce the electrostatic effect of shell HDPE. The electrical, mechanical, surface wettability and thermodynamic analysis of the samples were carried out by using ultra-high resistance measuring instrument, universal mechanical testing machine, surface contact angle tester and differential scanning Calorimeter. The results show that the surface resistance of wood-plastic composites with core-shell structure without SDBS is 10 ~ (15) 惟, and when 18% SDBS is added, the surface resistance of wood-plastic composites decreases to 10 鈮，
