The invention has the beneficial effects that:
the invention adopts the composition of fluorosilicone rubber, ethylene propylene diene monomer rubber and chloroprene rubber, and adds the components of vulcanizing agent, accelerating agent, stabilizing agent, corrosion-resisting agent and fire retardant. The fluorosilicone rubber has excellent hydrogen solvent resistance, oil resistance, acid and alkali resistance of the organic fluorine material due to the introduction of fluorine-containing groups on the basis of keeping the excellent performances of the organic silicon material, such as heat resistance, cold resistance, high voltage resistance, weather aging resistance and the like. The ethylene propylene diene monomer rubber has the advantages of aging resistance, outstanding electrical insulation performance, excellent weather resistance, heat resistance and corrosion resistance. Chloroprene rubber has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance and chemical reagent resistance, and has the defects of poor cold resistance and poor storage stability. The three components are compounded to exert excellent corrosion resistance and stability. The vulcanizing agents are SQS633 and SR633, so that the crosslinking density during vulcanization is improved, the vulcanization degree and the vulcanization speed are improved, and the hardness, the strength and the high-temperature resistance of the rubber can be improved. The accelerator ZDC and the accelerator PZ act synergistically with a vulcanizing agent to accelerate the vulcanization speed and improve the crosslinking degree and the heat resistance.
The corrosion-resistant agent ZS-1041 is resistant to high temperature, acid and alkali corrosion, resistant to thermal shock change and capable of enhancing the corrosion resistance and thermal stability of the sheath at high temperature. The stabilizer 8-hydroxyquinoline zinc salt, the maleic anhydride and the corrosion-resistant agent act synergistically to enhance the thermal stability and the corrosion resistance of the sheath. When the fire retardant decabromodiphenyl ether is decomposed, the free radicals generated by the degradation reaction of the high molecular material are captured, the burning chain reaction is delayed or terminated, and the released HBr is a flame-retardant gas and can cover the surface of the material to play a role in blocking the surface combustible gas. The zinc borate can improve the fire resistance of the protective sleeve, and covers zincate and boric acid to form a heat-insulating layer during combustion, so that the generation of combustible gas is inhibited, oxidation and heat are prevented, and a good smoke suppression effect is achieved. The water and carbon dioxide in the basic magnesium carbonate help to reduce the initial peak heat release and increase the ignition time, and the partial decomposition of huntite helps to reduce the heat release rate in the later stages of combustion, providing a physical barrier, slowing the release of combustible gases to the flame. However, basic magnesium carbonate has low flame retardant efficiency and low melt index. According to the application, the basic magnesium carbonate is modified by adding the silane coupling agent and the surfactant dodecyl trimethyl ammonium bromide or benzalkonium bromide, so that the activation performance of the basic magnesium carbonate is improved, and meanwhile, the basic magnesium carbonate is compounded with decabromodiphenyl ether and zinc borate, so that the flame retardant efficiency is greatly improved.
The cable sheath of the invention has good comprehensive performance: the elongation at break reaches more than 654% at normal temperature, the tensile strength reaches more than 27.9Mpa, and the mechanical property is excellent; soaking in 15% hydrochloric acid and 15% NaOH solution at normal temperature for 60 days to make the surface of the sheath flat and free of cracks; the oxygen index reaches more than 48, and the flame retardant property is good.
