Abstract

The invention discloses an EPDM/PE (Ethylene-Propylene-Diene Monomer/Polyethylene) mixture with high gel content. The EPDM/PE mixture contains the following components in parts by weight: 70-80 partsof EPDM, 20-30 parts of PE, 1 part of GMA (Glycidyl Methacrylate), 0.5-0.8 part of o-divinyl benzene, 0.1 part of an LCP (Liquid Crystal Polymer), 30 parts of mineral oil, 10 parts of butyl chloride and 0.3-0.5 part of DCP. Meanwhile, the invention further discloses a preparation method and a preparation device of the EPDM/PE mixture. The EPDM/PE mixture disclosed by the invention is high in gel content, high in tensile strength and low in thermal deformation, and the heat resistance is greatly improved.

Description

technical field [0001] The invention belongs to the field of wire and cable preparation, and in particular relates to an EPDM / PE mixture with high gel content, a preparation method and a preparation device thereof. Background technique [0002] Wire and cable are used to transmit electric (magnetic) energy, information and wire products to realize electromagnetic energy conversion. In the broad sense, wires and cables are also referred to as cables for short. In the narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts; one or more insulated cores, and their respective possible coatings. Protective layer and outer sheath, the cable may also have additional uninsulated conductors. The covering layers used for these wires and cables are mostly made of rubber. At present, ethylene propylene diene monomer (EPDM) is the most commonly used material for the covering layer of wires and cables. EPDM / PE (polyethylene) i...
