Interaction of Metakaolin-Phosphoric Acid and Its Fire Performance of Polypropylene Composite

摘要：

　　Metakaolin soaked in sulfuric acid for 2h to get a mid-product (S4) and then Calcined at different temperature(200,400,600,800℃) to give the acid-kaol(C2, C4, C6, C8).The modified kaolinite has also applied in polypropylene (PP) with intumescent flame-retardant (IFR).The flammability of PP/IFR/acid-kaol were studied by limiting oxygen index (LOI), vertical burring test (UL-94), LOI value of PP/25 wt.% IFR composite was 27.5%, it increased to 34.8% by 3.0wt.% S6 substitution with IFR.Moreover, its thermal stability has improved significantly.
