Abstract
The invention relates to a halogen-free cross-linked polyolefin cable material for energy storage cables, comprising the following components in mass fractions: a first elastomer resin: 25%-30%; its melt index under the condition of 190° C.×2.16kg is 1.7-3.1g / 10min; the first elastomer resin includes one or more of EVA, POE, EPDM and PE; the second elastomer resin: 10%-20%; its molecular weight is 35-450,000, including One or more of TPU, TPV and PET; flame retardant: 35%-50%, including inorganic clay and expandable graphite; flame retardant synergist: 2.0%-4.0%; compatibilizer: 5.0%- 12.0%, which is a grafted polymer of maleic anhydride, the melt index of the compatibilizer under the condition of 190℃×2.16kg is 0.5‑1g / 10min; Surface modifier: 0.4%‑1.2%; Crosslinking agent: 1.5 %‑3.5%; Antioxidant: 1.0%‑3.0%; Lubricant: 1.0%‑3.0%; Asphaltene: 1.0%‑3.0%. The halogen-free cross-linked polyolefin cable material for energy storage cables of the present invention has high flexibility, good elasticity, good flame retardancy and long service life at a working temperature of -40°C-125°C.
Description
technical field [0001] The invention relates to a halogen-free cross-linked polyolefin cable material for energy storage cables, in particular to a halogen-free cross-linked polyolefin cable material for energy storage cables. Background technique [0002] Since the energy required by people has strong temporal and spatial characteristics, in order to use energy reasonably and improve the utilization rate of energy, it is necessary to use a device to collect and store the excess energy that is temporarily unused for a period of time in a certain way. In the energy storage system (ESS), it can be extracted and used during peak usage, or transported to places where energy is scarce for reuse. With the maturity and scale of new energy sources such as photovoltaics, wind power, and nuclear energy, the development of energy storage is the key to solving the high penetration rate of renewable clean energy. The value of energy storage can be reflected in the links of "generation, ...
