Problems solved by technology

[0003] In the preparation process of the existing irradiated ethylene-propylene rubber polymer composite cables, the low compactness of the composite material affects the impermeability of the material, resulting in poor waterproof effect of the cable, and the cable composite material cannot effectively suppress smoke during the reaction process. As a result, the cable preparation process is not environmentally friendly. At the same time, the flame retardancy and weather resistance of the prepared cable are not good, which affects the service life of the cable.

Abstract

The invention discloses a preparation method of an irradiation ethylene propylene rubber polymer composite material cable. The preparation method comprises the following steps: (1) preparing an insulating material: weighing rubber, aluminum hydroxide, carbon black, a plasticizer, boron oxide, an ultraviolet radiation resistant agent and a silane coupling agent WD-50 in proportion, putting the weighed materials in an internal mixer, stirring and mixing the materials for 2-3 hours until the materials are uniform to form a rubber compound, adding a vulcanizing agent, performing vulcanizing for 22-28 minutes under the temperature of 150-170 DEG C, and performing extruding through a single-screw extrusion molding machine to obtain a rubber material A. According to the preparation method provided by the invention, the compactness of the cable composite material is enhanced, the impermeability is improved, and the effective waterproof performance of the cable is realized; the cable compositematerial is subjected to low-smoke or smokeless reaction in the reaction process, and the material is non-toxic, so that the environmental protection property in the cable preparation process is enhanced; meanwhile, the prepared composite material has relatively good thermal stability, so that the flame retardancy of the cable is enhanced, and the weather resistance is excellent.

Description

[0001] The invention relates to the field of cable preparation, in particular to a preparation method of an irradiated ethylene-propylene rubber polymer composite cable. Background technique [0002] The demand for cables in power construction is large, and they have certain requirements for flame retardancy and fire resistance. Because of their own flame retardancy and radiation resistance, most cables ensure their performance through insulation structure design. Therefore, insulating materials are an important direction for the development of cables, and polymer composite materials are often used to prepare cables. [0003] In the preparation process of the existing irradiated ethylene-propylene rubber polymer composite cables, the low compactness of the composite material affects the impermeability of the material, resulting in poor waterproof effect of the cable, and the cable composite material cannot effectively suppress smoke during the reaction process. As a result, th...
