几种PP基木塑复合材料流变行为的研究
Study On The Rheological Behavior Of Several PP/Wood-Plastic Composites
我国每年木材加工余下废弃木屑量在几百万吨以上，其它天然纤维如稻糠等达上千万吨。每年城市人口产生的废旧塑料达240～280万吨，如果能将这些废旧材料有效地利用起来，将产生巨大的经济与社会效益。木塑复合材料是以木纤维或植物纤维为主要组分，经过预处理使之与热塑性树脂或其它材料复合而成的一种新型材料，此类产品可替代相应木制品，可以节约大量森林资源，处理掉大量废旧塑料及木材加工中产生的废弃木粉，有利于保护并改善生态环境，是符合21世纪发展方向的环保型化工新材料。本文研究了各种木塑复合材料的流变行为,结果表明,各种木塑复合材料为典型的假塑性流体,在实验温度下,不但对剪切速率敏感,而且对温度也敏感。在各种木塑复合材料中,稻壳粉木塑复合材料的流动性最好。
hina made million tons wood a year, other natural fibers such as rice chaff up to 10 million tons. The urban population annually generated waste plastics 240 ~ 2,800,000 tons, If these waste materials can be effectively utilized,It will produce enormous economic ane social benefits,Wood-plastic composite materials based on wood fiber or vegetable fiber as the main component,If it can deal with a large number of wood processing waste plastics and waste wood flour produced,It will help protect and improve the ecological environment,It is consistent with the direction of development of environment-friendly new chenical materials of 21 century.The rheological behavior was studied in this paper, The results indicate that various Wood-Plastic Composites are the typical pseudo-plastic fluid,and they are not only sensitive to the shear rate, but also temperature in the experiment temperature range. The wood-plastic composites of rice husk powder have the best fluid in various wood-plastic composites.
