摘 要: | 对Al(OH)3阻燃的高密度聚乙烯/木粉复合材料研究结果表明:随木粉和Al(OH)3添加量的增加,Al(OH)3对复合材料的阻燃效率增加,高木粉添加量的复合材料氧指数达27.1%,Al(OH)3的阻燃效率达0.203。增加木粉含量,复合材料的拉伸强度和弯曲强度明显提高;但Al(OH)3对拉伸强度的影响不大,而明显提高弯曲强度。增加木粉和Al(OH)3的含量,均能明显降低复合材料的冲击强度,破坏复合材料的韧性。

Influence of Aluminium Hydroxide on Flame Retardancy and Mechanical Properties of PE-HD/Woodflour Composites |

Abstract: | Flame retardancy and mechanical properties of the composites of high-density polyethylene, woodflour and aluminium hydroxide (Al(OH) 3) were investigated. The flame retarding efficiency of the composites increased with increasing content of woodflour and Al(OH) 3, with a limiting oxygen index of 27.1 % and a flame retarding efficiency of Al(OH) 3 of 0.203 being obtained. While woodflour improved both the tensile and flexural strengths, Al(OH) 3 improved the flexural strength only. However, both woodflour and Al(OH) 3 were harmful to the unnotched izod impact strength of the composites. |
