Abstract

The invention discloses a preparation process of a polymer plastic film. According to the technical scheme, the preparation process of the polymer plastic film is characterized by specifically comprising the following steps of 1, preparing raw materials, namely taking, in parts by mass, 80-100 parts of polypropylene, 20-40 parts of polyethylene, 2-4 parts of an antioxidant, 1-1.5 parts of a coupling agent, 3-5 parts of a surfactant, 10-12 parts of a flexibilizer, 8-10 parts of montmorillonite powder, 2-5 parts of a lubricant and 12-15 parts of a degradable material; and 2, mixing the raw materials, putting the polypropylene, the polyethylene, the coupling agent, the antioxidant and the flexibilizer in a stirrer in parts by weight to be mixed, so that all the materials are fully dispersed and mixed. The added flexibilizer improves the toughening effect, so that the thermal deformation temperature is not changed or slightly reduced, the impact resistance is obviously improved, the addeddegradable material enables the film to have the functions and characteristics of the traditional plastic, and the film can be split and degraded in the natural environment after reaching the servicelife, thereby being beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of plastic film production and processing, in particular to a preparation process of a polymer plastic film. Background technique [0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as laminations.
