Fabrication and Study of Abandoned Glass Fiber/Polypropylene Flame-Retardant Fiberboard

Article Preview

Abstract:

In this paper, flame-retardant fiberboard was prepared by blend mastication and hot-pressing method, using abandoned glass fiber and polypropylene as raw materials and magnesium hydroxide as flame-retardant reagent. The optimized processing conditions were concluded through orthogonal experiment and the range analysis: magnesium hydroxide mass fraction 25% , polypropylene mass fraction 70% , hot-pressing temperature 180, hot-pressing pressure 10 Mpa. Under these conditions, properties of fiberboard were as follow: tensile strength 20.55 Mpa , bending strength 30.98 Mpa , impact strength 3.65 Mpa , limiting oxygen index 28.2%.
