【摘要】：以十二烷基苯磺酸鈉(SDBS)為抗靜電劑,將其加入到具有核殼結(jié)構(gòu)的高密度聚乙烯(HDPE)木塑復(fù)合材料中,以減小殼層HDPE的靜電效應(yīng)。采用超高電阻測量儀、萬能力學(xué)試驗(yàn)機(jī)、表面接觸角測試儀以及差示掃描量熱儀對樣品進(jìn)行電學(xué)、力學(xué)、表面潤濕性以及熱力學(xué)分析。結(jié)果表明:未添加SDBS的核殼結(jié)構(gòu)木塑復(fù)合材料的表面電阻率為10~(15)Ω;添加18%的SDBS后,木塑復(fù)合材料的表面電阻率降至10~8Ω。添加SDBS后,木塑復(fù)合材料的力學(xué)性能先上升后下降,彎曲強(qiáng)度較最高值下降約3.67%,彎曲模量較最高值下降約9.92%,沖擊強(qiáng)度較最高值下降約10.20%。復(fù)合材料表面潤濕性隨著殼層SDBS含量的增加而降低,殼層結(jié)構(gòu)HDPE基體結(jié)晶度則先降低后提高。
[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，
