摘要
以天然热塑材料木质素和LDPE-EVA为原料,研究了不同木质素以及增容剂含量对木质素/LDPE-EVA共混材料的力学及热性能影响。结果表明,20份木质素与LDPE-EVA共混效果较好,拉伸强度达到最大(25.88 MPa),较LDPE-EVA聚合物提高了9%,且共混物在100℃附近的吸热峰出现一定左移(3.6℃),降解性能增加;10份增容剂LDPE-g-MAH的加入使体系拉伸强度达到35.66 MPa,较未加增容剂时提高了26.6%,100℃附近的吸热峰进一步左移(2℃),降解性能小幅降低,显著提高了共混物的相容性。
The mechanical and thermal properties of lignin/LDPE-EVA blends were investigated with different offers of lignin and compatibilizer.The results indicated that the tensile strength of blends was increased to 25.88MPa（increase by 9% compared to the LDPE-EVA）and the decrease of endothermic peak and improvement of degradation were observed with filling 20 parts of lignin.In addition,the introduction of 10 parts of compatibilizer LDPE-g-MAH was the main reason for the continued increase of strength tensile and decrease of endothermic peak,which improved the compatibility of blends.
