偶联剂对木塑复合材料冲击强度与热膨胀性能的影响
DOI: 10.3969/j.jssn.1000-2006.2012.03.019, PP. 91-95
Keywords: 冲击强度,热膨胀,偶联剂,木塑复合材料
Abstract:
以高密度聚乙烯(hdpe6761)为基体,松木纤维(pine)为增强材料,mape(epoleneg2608)、mapp(exxelorva1840)和fusabond(wpc576d)为偶联剂,采用注塑法制备木塑复合材料(wpc),并测定了hdpe基体和不同配比wpc的热膨胀性能与冲击强度。结果表明:wpc的冲击强度明显低于高密度聚乙烯板(hdpe),较低的冲击强度是木塑复合材料的一个主要缺点,偶联剂的加入可以提高wpc的冲击强度;wpc的热膨胀系数明显低于hdpe,虽然偶联剂的加入可以较好地抑制热膨胀,但wpc的热膨胀系数的主要影响因素是木纤维的加入量及塑料基体的种类。
