PE (poly ethylene) film for wire and cable and preparation method of PE film

Abstract

The invention discloses a PE (poly ethylene) film for a wire and a cable and a preparation method of the PE film. The PE film is prepared from the following concrete materials in parts: 15-25 parts ofcrosslinked polyethylene, 8-16 parts of low-density polyethylene, 6-14 parts of medium-density polyethylene, 7-14 parts of polyisobutene, 4-8 parts of modified polyester fiber, 0.5-1 part of aluminumoxide, 0.8-3 parts of cellulose acetate, 2-6 parts of silica gel, 1-5 parts of dimethyl formamide, 1-5 parts of hydroxypropyl methyl cellulose, 2-6 parts of polyethylene terephthalate, 1.2-2.5 partsof nanoscale titanium oxide, 0.5-1.4 parts of nanoscale aluminum oxide, 0.6-1.5 parts of tetrabutyl titanate, 1.4-3 parts of methylphenol, 0.6-1.8 parts of magnesium stearate, 0.8-1.5 parts of an antioxidant and 1.5-3 parts of a plasticizer. The PE film prepared by the invention does not become aged, allochroic, cracked, brittle or pulverized under the action of atmosphere, sunlight and oxygen, the PE film has a relatively stable mechanical property and strong chemical stability simultaneously, and the PE film is simple in processing technology and low in raw material cost, thereby being suitable for production in quantity.

Description

technical field [0001] The invention relates to the technical field of PE films, in particular to a PE film for electric wires and cables and a preparation method thereof. Background technique [0002] PE film, that is, polyethylene film, refers to a film produced from PE film. PE film has moisture resistance and low moisture permeability. Polyethylene film (PE) can produce products with different properties such as low-density, medium-density, high-density polyethylene and cross-linked polyethylene according to different manufacturing methods and control methods. [0003] PE film has a wide range of applications. In the power industry, it is often used to wrap wires and cables. However, with traditional PE films, the adhesion between the PE protective film and the protected product is not firm, and it may fall off during transportation and use. , and the PE protective film product can be effectively peeled off, but there are residues of the protective film on the surface ...

Problems solved by technology

[0003] PE film has a wide range of applications. In the power industry, it is often used to wrap wires and cables. However, with traditional PE films, the adhesion between the PE protective film and the protected product is not firm, and it may fall off during transportation and use. , and the PE protective film product can be effectively peeled off, but there are residues of the protective film on the surface of the profile, because when the protective film is combined with the profile to be protected, it will encounter a suitable environment such as sunlight and moisture. At the same time, the traditional PE film is relatively poor in insulation and high performance resistance, and is prone to wear and tear. These problems need to be improved on the traditional PE film. Therefore, here we propose a wire and cable. PE film and its preparation method
