The halogen-free elastomer cable material for the thermoplastic wind energy cable is not required to be crosslinked after being subsequently prepared into a cable, the preparation process is simple, and the material can be recycled.
By the scheme, the invention at least has the following advantages:
1. in order to improve the flexibility and elasticity of the halogen-free elastomer cable material for the thermoplastic wind energy cable, the resin A with a specific melt index or molecular weight and the resin B with a high molecular weight are compounded, so that the material has better oil resistance on the premise of non-irradiation, can meet the requirement of the oil resistance of a wind energy cable sheath material (902# oil, 100 ℃, 24h, and the retention rate of strength and elongation at break is more than 75 percent), simplifies the production process and reduces the production cost. Wherein, the resin A is a block copolymer of ethylene, and the resin B is polyethylene resin, and the compatibility of the two is better.
2. In order to improve the flame retardance of the halogen-free elastomer cable material for the thermoplastic wind energy cable, the halogen-free elastomer cable material is compounded with a flame retardant and a flame retardant synergist, wherein the flame retardant simultaneously contains inorganic clay and expandable graphite, and the inorganic clay not only has flame retardance, but also can improve the flexibility and elasticity of the cable material. The expandable graphite is a graphite product obtained by taking natural crystalline flake graphite as a raw material and carrying out chemical or electrochemical treatment, and the expandable graphite can be instantly expanded when meeting high temperature and is changed into a worm shape from a sheet shape, so that the structure is loose, porous and bent, the specific surface area is large, the adsorption force is strong, the filling property is good, and the expandable graphite is used in a cable material, so that the dispersity of flame retardant particles and the compatibility with elastomer resin are improved, the improvement of the flame retardant property of the whole material is facilitated, and the smoke density is reduced; the dispersibility of the flame-retardant particles is improved, so that the light transmittance of the final cable material is high.
3. The compatilizer comprises a maleic anhydride grafted polymer with the melt index of 0.2-2.0g/10min, the maleic anhydride grafted polymer is suitable for the elastomer resin composition, and the maleic anhydride grafted polymer with the excessively high or excessively low melt index can not ensure the good compatibility of other components with the elastomer resin composition.
4. By adding a small amount of asphaltene into the halogen-free elastomer cable material for the thermoplastic wind energy cable, the asphaltene is not melted when being heated to more than 300 ℃, only decomposed into gas and coke, and no fraction is available, thereby avoiding the generation of toxic gas after asphalt combustion, having good insulativity and waterproofness, improving the service condition of the cable and prolonging the service life.
5. The low-temperature flexibility modifier is added into the cable material, so that the low-temperature flexibility modifier has a synergistic enhancement effect with the block copolymer of ethylene and the polyethylene resin in the cable material, and the low-temperature flexibility modifier has excellent low-temperature resistance performance of the material, reduces the glass transition temperature of the resin and improves the flexibility performance of the material at a lower temperature.
6. Because the addition amount of the PBT resin is less, the insulation property of the cable material is not influenced. The PBT resin with a small amount is added into the cable material, so that on one hand, the PBT resin has good affinity with a flame retardant and can play a certain flame retardant effect, and meanwhile, due to the crystallinity, a tiny crystal unit is formed in the cable material, so that the low-temperature flexibility of the cable material is improved.
7. Through the synergistic effect of the components, the halogen-free elastomer cable material for the thermoplastic wind energy cable has low hardness (78A), softness, high elasticity and torsion resistance, and particularly passes a torsion test (2500 times (2000 standard requirements)) at ultralow temperature (-60 ℃ (55 standard temperature)). The cable material disclosed by the invention has high flame retardant property after being prepared into a wire, can pass IEC60332-3-24C flame retardant test, and has low smoke density and light transmittance up to 86% (60% of standard requirement).
