| 摘 要：將兩種不同的堿木質(zhì)素（Lignin A和Lignin B）分別與乙烯-乙酸乙烯酯共聚物（EVA）在轉矩流變儀中共混后，經(jīng)平板硫化儀熱壓成片制得Lignin／EVA復合材料。探究了兩種堿木質(zhì)素的理化性質(zhì)及其對Lignin／EVA復合材料力學(xué)性能的影響。傅里葉紅外光譜分析（FT-IR）表明Lignin A以紫丁香基基本結構單元為主，Lignin B則以愈創(chuàng )木基、紫丁香基基本結構單元為主；Lignin／EVA復合材料的力學(xué)性能測試結果表明Lignin A／EVA復合材料的力學(xué)性能比Lignin B／EVA復合材料的力學(xué)性能好；掃描電子顯微鏡（SEM）測試結果表明Lignin A與EVA的共混相容性較Lignin B與EVA的共混相容性好。 |

| Abstract：Alkali lignin (Lignin A or Lignin B) was mixed with ethylene vinyl acetate copolymer (EVA) in a torque rheometer, and the obtained Lignin/EVA composites samples were prepared by hot pressing. The physicochemical properties of two alkali lignins and their effects on the mechanical properties of Lignin/EVA composites were evaluated. Data from Fourier transform infrared spectroscopy (FT-IR) showed that Lignin A was dominated by the basic structural unit of syringa, however, Lignin B was mainly composed of basic units of guaiacyl and syringa; the mechanical properties of Lignin A/EVA composites were better than that of Lignin B/EVA composites; the results of SEM indicated that the compatibility between Lignin A and EVA was better than that between Lignin B and EVA. |
