PE partition plate with anti-oxidation function

Abstract

The invention discloses a PE partition plate with an anti-oxidation function, which relates to the technical field of PE partition plates. The PE partition plate comprises a partition plate body, the front face and the back face of the partition plate body are connected with anti-oxidation protective films in an adhesive mode through hot melt adhesive layers, the top of the back face of each anti-oxidation protective film is connected with a PE base plate in an adhesive mode through an adhesive film, and the bottom of each PE base plate is connected with a flame-retardant film in an adhesive mode through an adhesive film. By arranging the PE base plate, the PE base plate is effectively protected on the outer wall of the partition plate body, ultraviolet rays and electric waves generated in the use environment of the partition plate are absorbed under the action of the ultraviolet ray absorption film and the electric wave absorption film arranged in the PE base plate, the mechanical strength of the partition plate is guaranteed, and the overall service life of the partition plate is prolonged; and meanwhile, through the action of an anti-aging protective film and an antioxidant coating film which are arranged outside the PE base plate, the use of the partition plate is effectively protected, the oxidation efficiency of the partition plate is reduced, the anti-oxidation effect of the PE partition plate is further improved, and the practicability of the partition plate is enhanced.

Description

technical field [0001] The invention relates to the technical field of PE separators, in particular to a PE separator with an anti-oxidation function. Background technique [0002] Polyethylene (referred to as PE) is a thermoplastic resin obtained 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, and has excellent durability. Low temperature performance (minimum operating temperature can reach -100~-70°C), good chemical stability, can withstand most acid and alkali erosion (not resistant to oxidizing acids), insoluble in general solvents at room temperature, low water absorption, and electric Excellent insulation; PE separator is an important component of the battery, it is placed between the positive and negative plates of the battery, the quality of the separator directly affects the discharge capacity of the battery and the service life of the charge-disc...
