Abstract

The invention relates to a halogen-free anti-flaming polypropylene material, which is characterized by comprising the following raw materials: 10 to 20 percent of first polypropylene copolymer, 27.5 to 47.5 percent of second polypropylene copolymer, 0.1 to 0.5 percent of thermal stabilizer of hindered phenol, 0.1 to 0.5 percent of thermal stabilizer monothioester, 0.1 to 0.5 percent of metal deactivator, 0.1 to 0.5 percent of processing stabilizer of phosphate ester, 2 to 10 percent of 1, 3-benzenediol bi(diphenyl phosphate ester), 0.1 to 0.5 percent of antacid agent of houghite and 30 to 50 percent of ammonium polyphosphate. The halogen-free anti-flaming polypropylene material is obtained by adopting polypropylene copolymer with the melt index of 0.2g / 10min to 0.5g / 10min and polypropylene copolymer with the melt index of 1g / 10min to 3g / 10min to carry out mixing combination, has excellent film-forming processability and can be made into films with different thickness between 0.2mm to 0.6mm.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant polypropylene material, which is mainly used for making high-voltage breakdown-proof insulating films of electronic appliances. Background technique [0002] Flame-retardant polypropylene film has good folding resistance and high-voltage breakdown resistance (can withstand high voltage above 5000V), so it has a wide range of applications in the electronic and electrical industry. At present, only polypropylene films using halogenated flame retardants can meet the stringent flame retardant requirements of the electrical and electronic industry. Halogenated flame retardants release a large amount of dense smoke and corrosive halides when burned, causing casualties and corroding various equipment, resulting in the so-called "secondary disaster". With the deepening awareness of the hazards of halogen flame retardant materials, almost all halogen flame retardant materials are gradually being replaced ...
