Formula and production process of CPP film

Abstract

The present invention discloses a formula of a CPP film, wherein a matting PP layer and a CPP base material layer are integrally polymerized to form the CPP film, 5-10 mg of an antistatic masterbatch is added to per cubic meter of the CPP base material layer, per cubic meter of the matting PP layer is coated with 2-5 mg of a polymer emulsion, and per cubic meter of the matting PP layer is further coated with 6-8 mg of a toughening agent. The production process comprises: 1, preparing a micro-emulsion; 2, coating the CPP base material layer by using an antistatic masterbatch, and heating; 3, coating the matting PP layer by using a toughening agent, and heating; 4, carrying out corona treatment; 5, coating the matting PP layer by using the micro-emulsion, and heating; 6, rapidly cooling on a cold casting roller; 7, winding; and 8, packaging. According to the present invention, with the formula and the production process of the PE film, the obtained product has characteristics of good toughness, high transparency, low temperature resistance, good heat sealing property, good sealing performance, no sticking on powder, low cost, and application range expansion.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a formula of a CPP film and a production process thereof. Background technique [0002] High-density polyethylene is a highly crystalline, non-polar thermoplastic resin. CPP has excellent resistance to most domestic and industrial chemicals. The polymer is non-hygroscopic and has good water vapor resistance for packaging purposes. CPP has good electrical properties, especially the high dielectric strength of the insulation, making it very suitable for wires and cables. The existing CPP black and white two-color and other colored films, in the production and use of waterproof membranes, the yellow waste engine oil in the asphalt penetrates into the surface of the CPP film, making the film yellow and affecting the appearance. Catalyst poisoning caused by silicone oil process. Moreover, most of the existing CPP film formulas and production processes have relatively s...

The existing CPP black and white two-color and other colored films, in the production and use of waterproof membranes, the yellow waste engine oil in the asphalt penetrates into the surface of the CPP film, making the film yellow and affecting the appearance. Catalyst poisoning caused by silicone oil process

Moreover, most of the existing CPP film formulas and production processes have single functions, processing and molding are not convenient enough, the quality is poor, the scope of application is relatively narrow, and cannot be applied to large-scale production. The produced CPP film has low toughness and relatively low transparency. Low, poor heat sealing and sealing performance, and easy to be contaminated with powder, not practical enough
