Abstract

The invention discloses a PP sheet preparation method and device. The method includes weighing 60-80 parts of polypropylene, 40-50 parts of butadiene styrene rubber, 1-2 parts of a stabilizer and 3-4 parts of a dispersing agent, granulating, then weighing 60-80 parts of the granulated materials, 30-40 parts of polypropylene resin, 4-6 parts of flame retardant masterbatch, 6-8 parts of color masterbatch and 1-2 parts of antibacterial masterbatch, mixing and fully stirring by a mixing device, and extruding a PP sheet through an extruder. By adding rubber, the prepared PP sheet has good elasticity and insulativity, materials are fully and uniformly mixed through the mixing device, and product performance differences are avoided.
