Description
Technical field
The present invention relates to a kind of cable jacket material, especially a kind of Cold resistant cable sheath material belongs to field of cable technology.
Background technology
It is well-known, current many cold-resistant cable materials, it is all hard in -50 DEG C and lower temperature, flexibility is had not a particle of, such as the digging electric cable used in mining, cold district needs the radar power transmission line rotated back and forth, need cable for elevator that often bending dragging is used etc., if cable does not reach cold-resistant condition, these cables can ftracture, and cause cable short circuit and equipment fault.
Even if not ftractureing, cable is all ice-cold and hard under cold conditions, it is impossible to bent back and forth and mobile, this, which gives, needs roving equipment to make troubles.
The content of the invention
The purpose of the present invention is that there is provided a kind of Cold resistant cable sheath material for above-mentioned the deficiencies in the prior art.The present invention has cold tolerance good, and fire resistance is high, deposits that period of storage is long, and intensity is high, and tear resistance is good, and salt fog resistance is good, smooth in appearance, is difficult incipient scorch, the advantage of easy processing.
The purpose of the present invention is achieved through the following technical solutions：A kind of Cold resistant cable sheath material, it is characterized in that, including following each component is prepared from by weight：100 parts of natural rubber, 8-16 parts of ethylene-vinyl acetate copolymer, 10-20 parts of di-n-octyl sebacate, 20-25 parts of calcium carbonate, 55-65 parts of antimony oxide, 1-2 parts of antioxidant, 3-4 parts of age resistor ODA-40,1-3 parts of accelerator, 1-2 parts of stearic acid, 4-5 parts of magnesia, 4-5 parts of zinc oxide, 1-3 parts of anti-termite agent.
The anti-termite agent is made up of by weight following components：5-15 parts of 70-90 parts of AVM, 5-15 parts of asarinin and Dihydrocapsaicin.
The accelerator is captax, Vulcanization accelerator TMTD, accelerant CZ.
The antioxidant is antioxidant 1010, anti-oxidant DLTP.
A kind of Cold resistant cable sheath material, it is characterized in that, including following each component is prepared from by weight：100 parts of natural rubber, 10-13 parts of ethylene-vinyl acetate copolymer, 15-18 parts of di-n-octyl sebacate, 22-24 parts of calcium carbonate, 58-62 parts of antimony oxide, 1-2 parts of antioxidant, 3-4 parts of age resistor ODA-40,1-3 parts of accelerator, 1-2 parts of stearic acid, 4-5 parts of magnesia, 4-5 parts of zinc oxide, 1-3 parts of anti-termite agent.
Natural rubber is generally chip solid, and relative density 0.94, refractive index 1.522,2~4MPa of elastic membrane amount softens at 130~140 DEG C, and 150~160 DEG C viscous soft, starts degraded at 200 DEG C.There are higher elasticity, slightly plasticity, crystallization at low temperatures hardening under normal temperature.There is preferable alkali resistance, but intolerant to strong acid.Water insoluble, lower ketones and alcohols, can be swelled in non-polar solven such as chloroform, carbon tetrachloride.
Ethylene-vinyl acetate copolymer closedcells structure, do not absorb water, moistureproof, water resistance it is good；The chemicals such as sea water resistance, grease, acid, alkali corrode, antibacterial, nontoxic, tasteless, pollution-free；Non junction, and be easy to carry out hot pressing, cut out, gluing, laminating etc. are processed；Resilience and tension stress are high, and toughness is high, with good shockproof, shock-absorbing capacity；Heat-insulated, heat-insulating and cold and low temperature performance excellent can cold-resistant and exposures；Closedcells, soundproof effect is good.
Di-n-octyl sebacate is cold-resistant plasticizer, with plasticizing efficiency is high, volatility is low, existing excellent cold resistance, there is preferable heat resistance, light resistance and electrical insulating property again.
The protective cover material that the present invention is provided, its cold resistance is high, and its resistance to low temperature can reach -40 DEG C, and the cold resistance of common neoprene only has -30 DEG C, it is impossible to the use for the regional removal cable that seasons oneself to cold.
The protective cover material that the present invention is provided, waiting time is long, can deposit one-year age under 40 DEG C of environment temperatures, and incipient scorch and vulcanization will not occur for its sizing material, extrudes smooth in appearance.
The protective cover material that the present invention is provided, fire resistance is high, and its oxygen index (OI) up to 42% or so, can substantially increase the fire-retardant rank and the scope of application of cable.
The protective cover material that the present invention is provided, its intensity is high, and tear resistance is good, and its tensile strength can reach more than 16.0N/mm2, and tear strength is up to 13.1N/mm or so, and high tensile strength improves cable physical burden.Larger tear strength improves cable wear resistance can be with resistance to torsional bending performance.
The protective cover material that the present invention is provided, resistance to saltfog is high, and it undergoes 672 hours in 90 DEG C, the aqueous solution containing NaCl30g/L, and its tensile strength and elongation at break are not in larger change compared with reset condition, are applicable very much in the larger environment of resistance to mist and use.
