一种绿色天然亚麻纤维增强聚丙烯树脂基复合材料的制备方法

Method for preparing green natural flax fiber reinforced polypropylene resin-based composite material

Abstract

The invention provides a method for preparing a green natural flax fiber reinforced polypropylene resin-based composite material. The method comprises the following steps of: putting flax fibers into water, regulating the pH of the solution to between 1 and 4, adding glutaraldehyde into the solution, and heating and preserving the heat to perform reaction to prepare modified flax fibers; and putting polypropylene resin granules into a hot-mixing stirrer, adding the modified flax fibers into the granules after the polypropylene resin granules are melted, and stirring the mixture to prepare thenatural flax fiber reinforced polypropylene resin-based composite material. In the method, the glutaraldehyde is used for modifying the surfaces of the flax fibers in aqueous solution to improve the adhesive performance of the flax fibers and the polypropylene resin matrix and remarkably improve the tensile strength and modulus of elasticity of the composite material. The obtained green natural flax fiber reinforced polypropylene resin-based composite material has excellent mechanical performance.
一种绿色天然亚麻纤维增强聚丙烯树脂基复合材料的制备方法,将亚麻纤维放入水中后调节pH为1~4,再加入戊二醛加热、保温反应得到改性亚麻纤维;取聚丙烯树脂粒料放入热混合搅拌机内,待聚丙烯树脂粒料熔化后加入改性亚麻纤维搅拌得到天然亚麻纤维增强聚丙烯树脂基复合材料。本发明在水溶液中用戊二醛改性亚麻纤维的表面,提高亚麻纤维与聚丙烯树脂基体的粘接性能,显著提高复合材料的拉伸强度与弹性模量。所得绿色亚麻纤维增强聚丙烯树脂复合材料具有优良的力学性能。
