百菌清对麦秸秆／PP复合材料耐腐蚀性能的影响

研究了百菌清作为抗菌剂对麦秸秆／PP复合材料耐腐蚀性能的影响，制备5种百菌清含量的麦秸秆／PP复合材料，参照ASTMG21—96对复合材料进行腐蚀实验，并测试腐蚀后麦秸秆／PP复合材料的力学性能、吸水性能、色差以及表面微观结构。结果表明：百菌清添加量为1．25％时，腐蚀后麦秸秆／PP复合材料的综合性能较好，与不添加抗菌剂的复合材料相比，弯曲强度、弯曲弹性模量、拉伸强度、冲击强度分别提高了13．71％，54．91％，10．46％，47．53％，吸水192h的吸水率降低了23．69％，腐蚀前后色差值则减小了11．56。

Effects of Chlorothalonil on Fungus Resistance of Wheat Straw/PP Composites

The effects of chlorothalonil as a fungicide on fungus resistance of wheat straw/PP composites were studied in this paper. Wheat straw/PP composites prepared with 5 different contents of chlorothalonil, were used in the experiment of fungus corrosion of composites with ASTMG21 -96 as the standard. Through the test, the me- chanical property, water absorption, chromatic aberration, microstructure surface of wheat straw/PP composites were observed after corrosion. The results showed that compared with wheat straw/PP composites with no addition of chlorothalonil, if the content of chlorothalonil was 1.25 %, mechanical property of composites was better after fungus corrosion, the bending strength increased by 13.71%, the bending modulus of elasticity increased by 54.91% , the tensile strength increased by 10.46% and the impact strength increased by 47.53% ,while water absorption ability and chromatic aberration were smallest, the bibulous rate reduced 23.69%, the color difference value reduced 11.56.
