Abstract

The invention discloses a low-cost and low-halogen transparent polypropylene film material and a preparation method thereof. The material is prepared from the following raw materials in parts by weight: polypropylene resin, a modification agent, a flame retardant, an antioxidant, a lubrication dispersing agent, terpene resin, an antistatic agent and the like, and is prepared by the steps of mixing the raw materials by using a high speed mixer, granulating by using a twin-screw extruder to obtain polypropylene resin granules, then adding the polypropylene resin granules into a three-roll calendered sheet extrusion molding machine to obtain the low-cost and low-halogen transparent polypropylene film material. The transparent polypropylene film material has the advantages of being low in cost, low in halogen content, good in transparency, and the like, can realize a UL-94 VTM-0 flame-retardant grade at 0.3mm or more, and maintains good high voltage breakdown resistance of polypropylene.

Description

technical field [0001] The invention relates to a film material, in particular to a low-cost low-halogen transparent polypropylene film material and a preparation method thereof. Background technique [0002] Polypropylene, English name: Polypropylene, abbreviated name PP. Its chemical formula is: (C 3 h 6 ) N. [0003] Polypropylene resin is a semi-crystalline thermoplastic. It has excellent properties such as non-toxic, light density, easy processing, chemical corrosion resistance, good electrical insulation, and good mechanical strength. It is widely used in daily necessities, electronic appliances, interior decoration materials, packaging materials, transportation, electromechanical and building materials, etc. Many fields. However, PP is a flammable material, and its oxygen index (LOI) is only 17.4 to 18.5. When burning, a large number of molten droplets are easily spread, which limits the application of PP in many fields. For the flame retardancy of PP, halogen-c...
