Title:
GLASS FIBER-REINFORCED, HALOGEN-FREE, AND FLAME-RETARDANT POLYPROPYLENE MATERIAL AND PREPARATION METHOD AND APPLICATION OF SAME
Document Type and Number:
WIPO Patent Application WO/2018/090802
Kind Code:
A1
Abstract:
The present invention discloses a glass fiber-reinforced, halogen-free, and flame-retardant polypropylene material and a preparation method and an application of the same. The material of the present invention is prepared from the following components in parts by weight: 20-50 parts of polypropylene, 5-30 parts of a phosphorus-nitrogen halogen-free intumescent flame retardant, and 30-50 parts of glass fibers, wherein the content of elemental calcium is 50-660 ppm, preferably 130-300 ppm, and more preferably 180-250 ppm based on the total weight of the glass fiber-reinforced, halogen-free, and flame-retardant polypropylene material. It was found unexpectedly that by controlling the content of elemental calcium in the polypropylene material to within a range of 50-660 ppm by adding a trace amount of elemental calcium to the glass fiber-reinforced, halogen-free, and flame-retardant polypropylene material, the polypropylene material had notably improved flame retardance and smoke suppression functions, excellent weather resistance, desirable heat resistance, water resistance, and corrosion resistance, and other features, and is thus a highly suitable plastic material for engineering plastic building templates. The glass fiber-reinforced, halogen-free, and flame-retardant polypropylene material according to the present invention can be widely applied in plastic building templates, and has high application value and a broad application prospect.
