Formula and production process of PE film

Abstract

The present invention discloses a formula of a PE film, wherein the base material is a polyethylene transparent film, and the matched material is formed by uniformly mixing and combining the following materials: 30-50 parts of metallocene linear low density polyethylene, 20-30 parts of smooth masterbatch, 10-15 parts of an antistatic masterbatch, 5-8 parts of a penetrating promoting agent, 2-5 parts of myrcene, 3-8 parts of a polypropylene resin, 4-8 parts of a styrene-butadiene rubber, 0.5-2 parts of silicone oil, 0.2-0.6 part of stearic acid, 2-5 parts of polyester fiber, 1-2 parts of cellulose acetate, 0.5-1 part of silica gel, 1-2 parts of aluminum oxide, 0.1-0.5 part of dimethylamide, and 1-2 parts of a light stabilizer. The production process comprises: 1, blending a primer; 2, unwinding; 3, coating the material; 4, drying; 5, cooling; 6, detecting; 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 reasonable design, convenient processing and molding, high strength, high transparency, strong flame retardant performance and strong antibacterial performance, and can emit fragrance so as to make the packaged product have the additional value.

Description

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

Moreover, most of the existing PE film formulas and production processes have relatively single functions, and the processing and molding are not convenient enough, the quality is poor, the scope of application is relatively narrow, and it cannot be applied to large-scale production. The produced PE film has low strength and relatively low transparency. Low, poor flame retardant and antibacterial properties, not practical enough
