Abstract

The invention discloses a production technology of nanometer modified polyolefin resin film, In the technology, un-stretched polypropylene film production process comprises: preparing modified nanometer silica, preparing modified nanometer montmorillonite, adding the prepared modified silica and modified montmorillonite into polypropylene homopolymers, adding dispersant, high speed banburing, melting, extruding and granulating to obtain parent material, melting the parent material, extruding, quenching, thickness measuring, corona treating, winding, cutting and packaging; and the production process of bidirectional stretched polypropylene film comprises an extra step of bidirectional stretching after the quenching step; wherein the weight percentages of the added substances are: modified silica 2%, modified montmorillonite 1.5%, F800E polypropylene homopolymers 93.5% and dispersant 3%. The invention solves problems of poor obstructing performance, relatively high oxygen transmittance, no antibacterial effect and insufficient rigidity of material existing in present CPP and BOPP films in our country; can prolong the shelf life of packing.

Description

technical field [0001] The invention relates to a production process of nanometer material modified polyolefin resin film. Background technique [0002] Polypropylene resin has become the fastest-growing variety among general-purpose resins, especially polyolefin film, which accounts for 40% of the entire plastic product industry due to its rich source of raw materials, low price, easy processing and molding, excellent product comprehensive performance and wide range of uses. about. The traditional polyolefin film process steps are to melt and extrude the polypropylene masterbatch, then undergo rapid cooling, thickness measurement, corona treatment, winding, slitting and packaging. The annual production capacity of BOPP in my country has reached 1.5 million tons, and that of CPP has reached 220,000 tons. Nevertheless, polyolefin films also have some disadvantages. For example, polyolefin films cannot be used for the packaging of electronic products such as electronic integ...
