Embodiment 1
[0028] 30 grams of isotactic polypropylene, 20 grams of polyolefin elastomer Dow Engage POE 8842, 0.25 grams of antioxidant 1010, 1 gram of flame retardant magnesium hydroxide and 0.25 grams of processing aid glyceryl stearate, at 180 Mixing at ℃ for 6 minutes, with a rotation speed of 60r / min, a recyclable insulating material for high-voltage DC cables is obtained, and its space charge performance is shown in figure 1 (b).
[0029] The recyclable high-voltage DC cable material obtained in the above implementation examples of the present invention still has a suitable storage modulus at 90° C., indicating that its mechanical properties have been greatly improved. At the same time from figure 1 (b) It can be seen that the material has good space charge suppression ability. From the perspective of comprehensive performance, the material meets the requirements of recyclable wire and cable insulation, does not require cross-linking in the preparation process, and is a recyclable...
