【摘要】:利用熔融法、溶液法制備聚丙烯接枝丙烯酸(PP-g-AA)、乙烯-辛烯共聚物接枝馬來酸酐(POE-g-MAH)、聚丙烯接枝馬來酸酐(PP-g-MAH)_3種大分子增容劑,用來改善木塑復(fù)合材料相容性問題?疾炱鋵(fù)合材料的力學(xué)性能、流變性能以及材料吸水性的影響。結(jié)果表明,添加PP-g-AA、POE-g-MAH和PP-g-MAH作為增容劑,木塑復(fù)合材料的性能都有所提高。其中,溶液法制得的增容劑,效果顯著。當(dāng)添加10%(wt,質(zhì)量分?jǐn)?shù))溶液法制得的PP-g-MAH,木塑復(fù)合材料的拉伸強(qiáng)度為25.21MPa,沖擊強(qiáng)度為4.014kJ/m~2,復(fù)合材料的扭矩達(dá)到5.8N·m,吸水率低至0.9%。
[Abstract]:Three kinds of macromolecular Compatibilizers, polypropylene grafting acrylic acid (PP-g-AA), ethylene-octene copolymer grafting maleic anhydride (POE-g-MAH) and polypropylene grafting maleic anhydride (PP-g-MAH), were prepared by solution method to improve the compatibility of wood-plastic composites. The effects of the composites on the mechanical properties, Rheological properties and water absorption of the composites were investigated. The results show that the properties of wood-plastic composites are improved by adding PP-g-AA,POE-g-MAH and PP-g-MAH as Compatibilizers. Among them, the Compatibilizer prepared by solution method has remarkable effect. When the tensile strength of PP-g-MAH, wood-plastic composites prepared by adding 10% (wt, mass fraction) solution is 25.21 MPA, the impact strength is 4.014 KJ 鈮,
