Modified nano high-strength polyethylene films

Abstract

The invention discloses modified nano high-strength polyethylene films which are prepared by combining the following process modules, wherein the process modules comprise an additive module, a pulp grinding and filtering module, a batching module, a mixing module, a kneading module, a molding module, a cooling module and a packaging and warehousing module; the output end of the additive module isthe pulp grinding and filtering module; the pulp grinding and filtering module can receive materials from the interior of the additive module; the strength adhesive module is added in the production process of the polyethylene films; therefore, under the action of the strength adhesive module, the high-density polyethylene module and the low-density polyethylene module can be better mixed and interacted; the inner core operation is carried out after the mixing process, so that the produced polyethylene films can be connected with each other more tightly, the phenomenon of gaps is avoided, andthe strength can be better enhanced by using the strength adhesive module.

Description

Technical field [0001] The invention belongs to the technical field related to polyethylene film production, and specifically relates to a modified nano high-strength polyethylene film. Background technique [0002] Polyethylene is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (minimum use temperature can reach -100 to -70°C), has good chemical stability, and can withstand most acids and alkalis (not resistant to oxidizing properties) Of acid). It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation. The performance of polyethylene depends on its polymerization method. High-density polyethylene is produced by Ziegler-Natta polymerization under medium pressure organic compound catalysis. Under this condition, the polymerized pol...
