| 摘 要： | 研究了羟甲基化木质素用量对PVC/NBR热塑性弹性体结构与性能的影响。结果表明：在100份（质量，下同）PVC/NBR中加入30份羟甲基化木质素时产物的综合性能最佳，拉伸强度25.6MPa，扯断伸长度520%，邵尔A型硬度77，撕裂强度72.7kN/m；耐老化性能在羟基甲基化木质素用量低于30份时较好；随着羟甲基化木质素用量增加，产物的耐油性能显著提高，动态粘弹分析证实羟甲基化木质素与PVC和NBR有较强的结合力，并且提高了PVC和NBR两相间的相容性。TEM观测发现木质素可在材料中形成第二个连续相，从而与基质构成互穿聚合物网络。

| Abstract: | The influences of lignin-resin(treated with formaldehyde) on the structure and properties of PVC/NBR thermoplastic elastomers were studied.When the lignin-resin was 30 phr,the properties were the best and the tensile strength,elongation at break,Shore A hardness and tear strength were 25.6 MPa,520%,77 and 72.7 kN/m respectively.Hot-air aging experiment showed that less content of lignin-resin(less than 30 phr) could increase enduring aging capability of PVC/NBR.Hot-oil resistance enhanced with the increase of lignin loading amount.Dynamic property indicated that lignin-resin had good compatibility with PVC/NBR,which improved the compatibility between PVC and NBR.TEM photos showed that lignin-resin shaped a second continuous phase,and formed a kind of IPN material with the matrix. |
