Abstract

The invention provides a polyethylene material capable of crosslinking in natural light as well as a preparation method and using method thereof, and particularly relates to a polyethylene material as well as a preparation method and a using method thereof. The invention aims at solving the problem that a conventional crosslinking method for preparation of the crosslinking polyethylene material has high crosslinking cost and high energy consumption. The polyethylene material capable of crosslinking in natural light is prepared from a dry polyethylene resin, a photoinitiator, an assistant crosslinker and an antioxidizer. The preparation method comprises the following steps of: firstly preparing a mixed solution of the photoinitiator, the assistant crosslinker and the antioxidizer, then adding the mixed solution to the dry polyethylene resin for preparation of a polyethylene resin which adsorbs the mixed solution, and pelleting the polyethylene resin adsorbing the mixed solution through a double-screw extruder, thus obtaining the polyethylene material capable of crosslinking in natural light. The using method comprises the following steps of: manufacturing the polyethylene material capable of crosslinking in natural light into sheets, and placing the sheets under sunlight for irradiation, thus obtaining natural-light crosslinking polyethylene material. The preparation method is used for preparing the polyethylene material capable of crosslinking in natural light.

Description

technical field [0001] The invention relates to a polyethylene material and its preparation method and use method. Background technique [0002] Due to its excellent electrical insulation, good chemical resistance and good processability, polyethylene is widely used in various fields of people's lives, especially in the wire and cable industry. However, in some special occasions, its performance cannot fully meet people's requirements for material performance, so a series of improvements have been made on polyolefin materials, and the most effective method is to crosslink polyolefin. After the material is cross-linked, its chain structure becomes a three-dimensional network structure. After cross-linking polyethylene, its tensile strength, impact strength, heat resistance, environmental resistance and chemical resistance are all improved, and its resistance Creep resistance, wear resistance, environmental stress resistance, cracking performance and bonding performance have ...
