Description
Technical field
The present invention relates to a kind of cable material and preparation method thereof, relate in particular to a kind of HDPE and LLDPE blend cable plastics and preparation method thereof.
Background technology
Cable electric cable; Power cable, normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and often round Yi Gen center, be twisted into, whole outside is surrounded by the tectum of high-insulation.
Electric wire mainly comprises bare wire, insulated wire and insulated line, power cable, telecommunication cable and optical cable for electrical equipment and electrical.Electric wire refers to the material for electric power, communication and associated transport purposes." electric wire " and " cable " do not have strict boundary.Conventionally core number is few, product diameter product little, simple in structure is called electric wire, not insulation be called bare wire, other be called cable; Long-pending larger (being greater than 6 square millimeters) of cross-sectional area of conductor is called large electric wire, and less (being less than or equal to 6 square millimeters) is called little electric wire, and insulated line is called again cotton covered wire.
Wires and cables industry is the second largest industry that China is only second to automobile industry, and range of product meets rate and domestic market occupation rate all over 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first electric wire producing country in the world.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.
China's economic growth continuously and healthily, for cable products provides the huge market space, the incentive that Chinese market is strong, makes the world all sight be focused on to Chinese market, reforming and opening up to the outside world short decades, the formed huge throughput of Chinese cable manufacturing industry allows the world regard with special esteem.Continuous expansion along with industry sizes such as China Power industry, data corresponding industry, urban track traffic industry, car industry and shipbuildings, also will increase rapidly the demand of electric wire, and following electric wire industry also has huge development potentiality.
In November, 2008, China is reply world financial crisis, and government decided drops into 4 trillion yuan and pulls domestic demand, wherein have about more than 40% for urban and rural power grids construction and upgrading.Whole nation wires and cables industry has had again the good market opportunity, and various places electric wire enterprise seizes the opportunity, and meets the construction and upgrading of new round urban and rural power grids.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention provides a kind of HDPE and LLDPE blend cable plastics, has good antistatic property.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned HDPE and LLDPE blend cable plastics.
The present invention seeks to be achieved through the following technical solutions:
A kind of HDPE and LLDPE blend cable plastics, component by following weight parts forms: HDPE100 part, LLDPE50-60 part, 1010 oxidation inhibitor 0.2-0.4 parts, Union carbide A-162 0.2-0.4 part, N, two (2-hydroxyethyl)-N-(3 '-dodecyloxy-the 2 '-hydroxypropyls of N-) methylsulfuric acid ammonium methyl 0.2-0.4 part, organic silicon acrylic ester 0.01-0.03 part, Zinic stearas 0.2-0.4 part.
The present invention also provides the preparation method of above-mentioned HDPE and LLDPE blend cable plastics: by proportioning, take each raw material, after mixing, melting mixing, extruding pelletization, obtain described HDPE and LLDPE blend cable plastics.
Mixed processes can carry out in general mixing machine, controls rotating speed at 300-400 rev/min, and melting mixing, extruding pelletization operation can be carried out in general screw extrusion press.
Obviously, for improving other performances of product, can also add adaptively other auxiliary agents, as photostabilizer, oxidation inhibitor, tinting material and static inhibitor etc. in the present invention.
Polyethylene (PE) is one of five large synthetic resins, and polyethylene is mainly divided into LLDPE (LLDPE), Low Density Polyethylene (LDPE), high density polyethylene(HDPE) (HDPE) three major types.
LLDPE (Linear Low-Density Polyethy-lene), english abbreviation is LLDPE.Linear low density polyethylene is structurally different from general Low Density Polyethylene, because there is not long-chain branch.The linear lag of LLDPE depends on the different process of manufacture of LLDPE and LDPE.LLDPE conventionally under lower temperature and pressure, is closed and generates as butylene, hexene or octene copolymer by ethene and senior a alkene.The LLDPE polymkeric substance that polymerization process generates has the molecular weight distribution narrower than general LDPE, has linear structure simultaneously and makes it have different rheological characteristicss.The suitable l of melt flow characteristics of LLDPE answers the requirement of novel process, particularly uses film expressing technique, can the high-quality LLDPE product of output.LLDPE be applied to polyethylene all traditional cities often strengthened anti-ly stretch, anti-ly penetrate, the performance of shock resistance and anti tear makes LLDPE be suitable for doing film.Its excellent environmental stress crack resistance, low-temperature impact resistance and anti-warpage properties make LLDPE all attractive to tubing, sheet material extrusion molding and the application of all moldings.The up-to-date application of LLDPE is the lining for waste residue landfill and waste liquid pool as mulch film.
Linear low density polyethylene (LLDPE), that ethene and a small amount of high alpha-olefin (as butene-1, hexene-1, octene-1, tetramethyl-amylene-1 etc.) are under catalyst action, a kind of multipolymer forming through high pressure or low-pressure polymerization, density is between 0.915～0.940 gram/cc.But the D-1248-84 regulation of pressing ASTM, the density range of 0.926～0.940 gram/cc belongs to medium-density polyethylene (MDPE).The LLDPE of a new generation is extended to plastomer (0.890～0.915 gram/cc) and elastomerics (<0.890 gram/cc) by its density.But U.S. association of plastics industry (SPI) and the U.S. plastics industry council (APC) only by the range extension of LLDPE to plastomer, do not comprise elastomerics.The eighties in last century, Union Carbide HeDow Chemical company is referred to as very low-density polyethylene (VLDPE) and ultra-low density polyethylene (ULDPE) resin by its early stage plastomer and elastomerics of selling.
High density polyethylene(HDPE) (High Density Polyethylene, referred to as " HDPE ") is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.The milky appearance of ortho states HDPE, is to a certain degree translucent in meagre cross section.PE has good resistance to great majority life and the characteristic of chemicals for industrial use.The chemical of some kind can produce chemical corrosion, for example corrosive oxidation agent (concentrated nitric acid), aromatic hydrocarbon (dimethylbenzene) and halon (tetracol phenixin).Non-hygroscopic and the steam-preventing that had of this polymkeric substance, can be used for packing purposes.HDPE has good electrical property, and particularly dielectric strength is high, makes it be applicable to very much electric wire.In to high molecular grade, there is fabulous shock resistance, even all like this under-40F low temperature at normal temperature.
HDPE of the present invention and LLDPE blend cable plastics, using LLDPE as properties-correcting agent, can effectively improve the fragility of pure HDPE goods, improves toughness and intensity, and CABLE MATERIALS surfaceness is low, can be widely used in built on stilts, buried and telecommunication cable.
