Description
Technical field
The invention belongs to a kind of cable jacket material, specifically, particularly relate to a kind of cable for wind power generation sheath material.
Background technology
Wind-power electricity generation has lot of advantages relative to conventional Power Generation Mode.Such as wind resource is a kind of renewable resources, utilizes wind-power electricity generation to reduce environmental pollution, saves the conventional energy resources such as coal, oil.Wind generating technology is ripe in addition, and advantage of lower cost in renewable energy source, has vast potential for future development.Wind generating technology can flexible Application, both can be incorporated into the power networks, and also from net independent operating, can also form complementary power generation system with other energy technology.Cable for wind power generation, due to residing bad environments, is often subject to the erosion of storm wind heavy rain, being exposed to the sun of burning sun sunlight, and blower fan is longer for working life, and cable with blower fan month after month do not stop transport throughout the year turn, higher to the performance requriements of cable.Cable for wind power generation is operated in special environment, has higher requirement to performances such as its low-temperature bending performance, twisting property, anti-cracking performance, corrosion resistance natures.The wind electric power generation cable result of use used in the market is not ideal, what mainly the sheath material of wind electric power generation cable was selected is the polymer crystallization material that polyethylene or urethane etc. have plastic properties, when causing wind electric power generation cable to use out of doors, after natural low temperature environment cracking, ultraviolet ray ageing become fragile cracking and acid and alkali corrosion, the physical and mechanical properties of sheath is deteriorated, cause cable to scrap, cause extreme loss to applying unit.High density polyethylene(HDPE) (HDPE) uses one of maximum starting material in modern plastics.It has the thermotolerance of good physical strength, toughness and excellence, insulation and chemical stability.But also have an even more important performance requriements to be exactly environmental stress crack resistance for high density polyethylene(HDPE), due to the structure problem of its material itself, make it very responsive to environmental stress, affect the work-ing life of material.So, the weathering resistance of the wind electric power generation cable sheath used on the market at present, physical and mechanical properties and flexibility and oil-proofness to be improved.
Summary of the invention
The object of the invention is to provide a kind of wind-power electricity generation warp resistance antifatigue cable jacket material, the defect that during to overcome that in prior art, wind power generation cable sheath uses out of doors, the physical and mechanical properties of sheath is deteriorated after natural low temperature environment cracking, ultraviolet ray ageing become fragile cracking and acid and alkali corrosion.
The present invention realizes by the following technical solutions:
A kind of wind-force hair cable jacket material, be made up of the material of following weight part: HDPE70-85 part, properties-correcting agent 15 ~ 30 parts, amorphism copolymer 1 5-25 part, Shawinigan black 20-25 part, cold resistant plasticizer 10 ~ 20 parts, reinforcing filler 20 ~ 35 parts, nanoscale inorganic active agent 5 ~ 15 parts, linking agent 1 ~ 3 part, additional crosslinker 2 ~ 5 parts, 1 ~ 3 part, anti-aging agent, inorganic combustion inhibitor 10 ~ 20 parts.
