Preparation and Properties of Poly(vinyl chloride)/Metakaolin Based Geopolymer Composites
摘要
Abstract
Poly(vinyl chloride)/metokaolin based geopolymer composites were prepared by mixing and melting the poly(vinyl chloride) (PVC) resin with initial gel stage geopolymer. Influences of geopolymer content on fusion, mechanical and heat deformation properties, and morphology of fractured section of PVC/geopolymer composites were investigated. It was found that the incorporation of lower content of geopolymer (i.e, ≤8%(wt)) would improve the plasticizing process of PVC resin, and small geopolymer particles are formed and well disperse in PVC matrix with good interface adhesive. In this case, compared with pure PVC, the geopolymer composites have good mechanical properties when their geopolymer contents are less then 8%(wt), and among them, the geapolymer composite with 4%(wt) geopolymer is the best, its impact strength reaches 9.16 kJ×m-2, which is abont 40%higher than that of pure PVC. When the geopolymer content is too high, the plasticization of PVC becomes difficult, the size of geopolymer particles increases and its interface adhesive with PVC decreases, which would lead to the decrease of tensile and impact strengths of PVC composites. Incorporation of geopolymer would improve the heat deformation resistance of PVC composites, and lead to the increase of Vicat heat deformation temperature of PVC composites.关键词
