Description
Technical field
The present invention relates to a kind of corrosion-resistant macromolecular material for power cable protective layer, belong to technical field of polymer materials.
Background technology
Power cable is the cable for transmitting and distribute electric energy.Be usually used in Urban Underground electrical network, the lead line in power house, the in-line power of industrial and mining enterprises and cross river, excessively extra large submarine transmission line.In electric power circuit, the proportion shared by cable increases just gradually.Power cable is in order to transmission and the cable product distributing high-power power in the basic routing line of power system.The basic structure of power cable is made up of core (conductor), insulation layer, screen layer and protective layer four part.The effect of protective layer is protection power cable from the intrusion of introduced contaminants and moisture, and prevents external force from directly damaging power cable.
In recent years along with the appearance of haze phenomenon, Air Quality worse and worse, no matter be that overhead cable or buried cable are all subject to certain impact, overhead cable is exposed in air for a long time, be subject to Exposure to Sunlight, high temperature, ozone, acid rain, the erosions such as the objectionable impurities in greasy dirt, air, buried cable is then vulnerable to termite, mouse gnaws, and underground sewage corrosion etc., especially in coastland, corrode by sea wind wave throughout the year, seawater alkalescence is high, has certain corrosive attack to wire material, shortens the life-span of cable to a great extent.
Summary of the invention
The object of the present invention is to provide a kind of corrosion-resistant macromolecular material for power cable protective layer, there is oil resistant, heat-resisting, fire-retardant, resistance to daylight, resistance to ozone, ageing-resistant, the features such as acid and alkali-resistance.
The described corrosion-resistant macromolecular material for power cable protective layer, is made up of the raw material of following weight part:
High density polyethylene(HDPE) 30-40 part, thiorubber 15-30 part, terpolymer EP rubber 10-20 part, chloroprene rubber 20-30 part, antioxidant D 0.5-1 part, antioxidant 4010 1-2 part, photostabilizer NBC 1-2 part, sepiolite 4-6 part, white carbon black 2-5 part, epoxy resin 3-6 part, magnesium oxide 1-3 part, vulcanizing agent PM 5-8 part, vulcanization accelerator TMTD 3-5 part, 3-aminopropyl triethoxysilane 0.3-1 part, dioctyl terephthalate 8-10 part, tricresyl phosphite isooctyl acrylate 7-11 part, aluminium hydroxide 15-30 part, calcium carbonate 10-20 part, Ca Zn composite stablizes 7-10 part, Ursol D 0.5-1.5 part, polyethylene wax 1-5 part, rosin 1-5 part.
Preferably for the corrosion-resistant macromolecular material of power cable protective layer, be made up of the raw material of following weight part:
High density polyethylene(HDPE) 35 parts, thiorubber 20 parts, terpolymer EP rubber 15 parts, chloroprene rubber 25 parts, antioxidant D 0.7 part, antioxidant 4010 1.5 parts, photostabilizer NBC 1.5 parts, sepiolite 5 parts, white carbon black 3 parts, epoxy resin 5 parts, 2 parts, magnesium oxide, vulcanizing agent PM 6 parts, vulcanization accelerator TMTD 4 parts, 3-aminopropyl triethoxysilane 0.6 part, dioctyl terephthalate 9 parts, tricresyl phosphite isooctyl acrylate 9 parts, 20 parts, aluminium hydroxide, 15 parts, calcium carbonate, Ca Zn composite stablizes 8 parts, Ursol D 1 part, polyethylene wax 2 parts, rosin 3 parts.
High-density polyethylene material density is higher, good crystallinity, and degree of crystallinity is large, and molecular layer intermolecular forces is large, and macro manifestations is that density of material is high, the better mechanical properties such as tensile strength, and material hardness is high, and abrasion resistance properties is excellent, and resistance to chemical corrosion is good; But material flexibility is slightly poor.Thiorubber has the excellent properties such as low-temperature flexibility, solvent resistance, stress relaxation, after thiorubber mixes with epoxy resin, the thiol group of end and epoxy resin generation chemical reaction, thus enter in the epoxy resin structural after solidification, impart the good snappiness of epoxy resin, high shearing resistance and the stripping strength after being cross-linked.Chloroprene rubber has good physical and mechanical properties, and oil resistant is heat-resisting, resistance to combustion, resistance to daylight, resistance to ozone, acid and alkali-resistance, chemical-resistant reagent, and have higher tensile strength, elongation and reversible crystallinity, cementability is good; Shortcoming is that winter hardiness and package stability are poor.Terpolymer EP rubber has excellent resistance to weather, resistance to ozone, heat-resisting, acid and alkali-resistance, resistance to water vapor, colour stability, electrical property, oil-filled property and normal temperature mobility, because it lacks polarity, degree of unsaturation is low, thus all has good resistance to various polar chemical product such as alcohol, acid, alkali, oxygenant, refrigeration agent, washing composition, vegetable and animals oils, ketone and fat etc.; But belong at fat and belong to less stable in solvent (as gasoline, benzene etc.) and mineral oil with virtue.Aluminium hydroxide itself is fire retardant, can as flame retardant filler.Sepiolite has the performances such as extremely strong absorption, decolouring and dispersion, and also have high thermostability, high thermal resistance can reach 1500 ~ 1700 DEG C, and formative nature, insulativity, anti-salinity are all very good.Using sepiolite and white carbon black as weighting agent, mainly in order to reduce product cost, reduce the consumption of resin, the reinforcing property of sepiolite is close to white carbon black, but price comparatively white carbon black is cheap, and acid and alkali-resistance, resistance to chemical attack ability are strong, and in rubber item, dispersing property is good, be the desirable packing strengthening agent of rubber item, can significantly reduce costs.Dioctyl terephthalate is a kind of environment-friendlyplasticizer plasticizer, has the performances such as outstanding electric durability energy, heat-resisting, low second-order transition temperature, low volatility, is the desirable softening agent producing excellent CABLE MATERIALS.Antioxidant 4010 is one of excellent universal anti-aging agent of natural rubber and synthetic rubber, excellent to aging action protective benefitses such as heat, oxygen, ozone, light, is also the excellent lasting be full of cracks of mechanical stress formation and the inhibitor of flex crack.Also have the solarization of high-energy radiation and cupric ion and necessarily have protective effect.The thermostability of calcium-zinc composite stabilizing agent is close or exceed some barium/cadmium stabilizer, Pb stabilizer, and the good weatherability of this kind of stablizer, nontoxic, be of value to HUMAN HEALTH and environment protection.
Compared with prior art the invention has the beneficial effects as follows:
The power cable protective layer material that the present invention produces has excellent physical and mechanical properties; combination of flexibility and hardness; tensile strength, stress relaxation, tearing toughness and screen resilience performance are strong, simultaneously excellent to aging action protective benefitses such as heat, oxygen, ozone, light.The present invention with high density polyethylene(HDPE), thiorubber, terpolymer EP rubber and chloroprene rubber are major ingredient, by rational proportion, greatly improve the corrosion resistance nature of product, oil resistant, heat-resisting, resistance to combustion, resistance to daylight, resistance to ozone, ageing-resistant, acid and alkali-resistance, chemical-resistant reagent, resistance to weather, resistance to water vapor, delay the aging speed of CABLE MATERIALS simultaneously, extended working life, save production cost.Because the present invention has high thermostability and erosion resistance, and environment-protecting asepsis, therefore can be widely used in power cable protective layer.
