Abstract
The invention provides a torsion and cold resistant flame-retardant sheath rubber for wind power generation flexible cables. The sheath rubber is composed of: 65-75 parts of chlorinated polyethylene; 15-25 parts of ethylene-propylene-diene monomer rubber; 10-20 parts of nitrile rubber; 10-15 parts of an active agent; 6-9 parts of a stabilizer; 1-3 parts of an antioxidant; 28-45 parts of a flame retardant; 10-20 parts of a low temperature plasticizer; 30-36 parts of a reinforcing agent; 10-20 parts of a filling agent; 1-2 parts of a lubricating assistant; 1-2 parts of a carbon black dispersing agent; 1-2 parts of a silane coupling agent; and 5-10 parts of a composite vulcanizing agent. The sheath rubber has a rubber content of 40-45%, which is the percentage ratio of the weight sum of the chlorinated polyethylene, the ethylene-propylene-diene monomer rubber and the nitrile rubber to the total weight of the sheath rubber. In the invention, three rubber materials are adopted simultaneously, and the composite flame retardant is added to improve the flame retardant property of the sheath rubber. A sheath rubber end product has very good torsion resistance, cold resistance and flame retardant property.
Description
Technical field
The present invention relates to the sheath rubber that a kind of cable is used, particularly the resistance to fire retardant jacket rubber that resists cold of turning round for wind-power electricity generation flexible cable.
Background technology
The whole world is all in the discharge of paying close attention to greenhouse gases, along with the industrialized development in the whole world, more and more to the demand of the energy at present.Past we to obtain the energy be mainly to rely on the oil coal that increases consumption to obtain, this will greatly increase the discharge of greenhouse gases, accelerates the process of Greenhouse effect, brings eco-catastrophe to the whole world.So global each state is all greatly developing renewable energy source.Country has put into effect " Renewable Energy Law ", encourage energetically the development of wind energy, sun power, water energy, biomass energy, wherein wind-power electricity generation is the technology of comparative maturity, it is high that it has concentration degree, construction period is short, and investment intensity is moderate, and I is built the little power supply system in only family or several villages, can build greatly the large-scale wind generating factory of million kilowatt, wind-power electricity generation is several years ago and in the quite a long time from now on all will presenting the trend of great-leap-forward development.China's wind-power electricity generation its technical is multiple countries from the whole world, and many companies introduce, and the cable overwhelming majority is import.Cable for wind power generation is owing to using region constantly to expand, and Construction of Wind Power is more and more to the cold zone such as the north of a desert, Gobi desert; High temperature, the high humiditys such as sea, island have the occasion development of salt fog.The place that this class envrionment conditions is more severe, has proposed many new requirements such as cold-resistant, low-temperature torsion resistance, wet fastness, salt spray resistance with cable to wind-powered electricity generation, meeting these new demands is exactly the trend of current wind-powered electricity generation cable development.
Wind-power electricity generation flexible cable should have the resistance to property turned round, winter hardiness, flame retardant resistance, oil-proofness and higher mechanical and physical performance with sheath rubber.In the past, each enterprise adopts company standard, and user is not high with the resistance to property the turned round winter hardiness of sheath rubber specification of quality to wind-powered electricity generation flexible cable, and the family expenses CPE of cable factory monobasic sizing material is filled a prescription just passable; But wind-powered electricity generation flexible cable cold tolerance from-20 DEG C till now-40 DEG C, the resistance to performance of turning round is from ± 4 circles ,-40 DEG C or-20 DEG C 100 times till now 2000 times; Had again at present technical specifications " voltage rating 1.8/3kV and following torsion-resisting soft cable for wind power generation " (TICW1-2009), user has improved much with the specification of quality of the resistance to property the turned round winter hardiness of sheath rubber flame retardant resistance wind-powered electricity generation flexible cable.
Chinese patent ZL200710047647.X " high-strength cold hardiness cable sheath rubber and preparation technology thereof ", what in the formula of its disclosed eraser sheath, adopt is that chlorinated polyethylene resin is as sizing material.Formula of rubber in Chinese patent ZL200610161495.1 " ethylene-propylene rubber for electric wire and cable " adopts ethylene-propylene rubber(EPR) as sizing material.The rubber material that this class monobasic sizing material is skeleton is difficult to reach the requirement that the requirement of winter hardiness, flame retardant resistance, oil-proofness, particularly cold tolerance are difficult to reach cold-resistant-40 DEG C cryogenic tensile on finished sheath simultaneously; Do not reach the requirement of cold-resistant-40 DEG C low temperature torsion 2000 times yet.
Summary of the invention
The object of this invention is to provide and a kind ofly turn round cold-resistant fire-retardant sheath rubber for resistance to for wind-power electricity generation flexible cable, this rubber can meet " voltage rating 1.8/3kV and following torsion-resisting soft cable for wind power generation " (TICW 1-2009) requirement with sheath rubber completely.
The technical scheme that realizes the object of the invention is the resistance to fire retardant jacket rubber that resists cold of turning round for a kind of wind-power electricity generation flexible cable, and the composition of described sheath rubber and proportioning are: 65～75 parts of chlorinatedpolyethylenees; 15～25 parts of terpolymer EP rubbers; 10～20 parts of paracrils; 10～15 parts of promoting agents; 6～9 parts of stablizers; 1～3 part, oxidation inhibitor; 28～45 parts of fire retardants; 10～20 parts, low temperature softening agent; Strengthening agent 30-36 part; 10～20 parts of weighting agents; 1～2 part of lubricating auxiliary agent; 1～2 part of carbon black disperser; 1～2 part of silane coupling agent; 5～10 parts of composite vulcanizing agents; The gel content of described sheath rubber is 40～45%; Described gel content is (weight of the weight+paracril of the weight+terpolymer EP rubber of chlorinatedpolyethylene)/gross weight × 100%.
