Abstract

The invention belongs to the field of plastic products, and discloses a preparation method of a polypropylene plastic film. The polypropylene plastic film is prepared from, by weight, 55-65 parts of polypropylene resin, 10-25 parts of polypropylene, 5-8 parts of polypropylene glycol, 3-8 parts of methyl methacrylate, 4 parts of magnesium stearate, 5 parts of allyl thermoplastic elastomer, 3 parts of dibutyl phthalate plasticizer, 3 parts of corn fiber toughener and 4 parts of zinc borate fire retardant. The preparation method includes the steps that polypropylene resin, polypropylene, polypropylene glycol, methyl methacrylate, magnesium stearate, allyl thermoplastic elastomer, the plasticizer, the toughener and the fire retardant are mixed and then molten at a certain temperature, extrusion blow molding is carried out through a circular port die of a screw extruder, drawing and cooling are carried out, and the film is formed.

Description

technical field [0001] The invention relates to a plastic film, in particular to a preparation method of a polypropylene plastic film. Background technique [0002] With the development of the economy, plastics have been widely used in industry and life. There are also many types of plastics, including those with flame retardancy and high temperature resistance. As a large class of general-purpose materials, polypropylene is widely used for its small specific gravity, easy processing, corrosion resistance, non-toxicity and excellent comprehensive performance. Ordinary polypropylene is easy to age under heat due to its active groups, but it is also easy to mutate with polypropylene after adding antioxidants, resulting in a decrease in the performance of polypropylene. Most films have problems such as poor physical stability, low mechanical strength, and flammability. Contents of the invention [0003] The purpose of the present invention is to provide a preparation metho...
