Description
Technical field
The present invention relates to technical field of polymer composite materials, be specifically related to a kind of thermoplastic elastomer, preparation method, it is used and by its cable sheath tube of processing.
Background technology
Existing high-tension electricity transmission directly is exposed in the air with steel core aluminium strand bare wire; Aspect problems such as the loss that reasons such as ponding, icing, the burn into that the various climate changes that experience is more and more complicated bring touches cause, safety; At the beginning of 2008; The southern china most of areas suffers nearly 50 years snowstorm disasters of not meeting, and causes a lot of local many transmitting line broken strings in south, the bar that falls.Power department hopes cable is installed additional protecting jacket, mainly acts in the hope of reaching the anti-ice-snow agglomerative, and requiring sheath is assembly type, and the little condition of giving birth to heat of outdoor all-weather environment and cable that adapts to is used.
Protecting pipe is an insulation protection heat-shrinkable T bush commonly used on a kind of cable.The oversheath of electric wire must be able to be protected the internal and external conductor of cable and influence and other physical damage that insulation layer is avoided environment, weather, hydrolytic action.At present, the sheath material of electric wire mainly contains PVC, general SEBS blend, thermoset rubber or various natural or synthetic elastomerics etc., wherein is the thermoset rubber of representative with EPDM, because the irreversible processing of thermosetting material; Must vulcanize by HTHP, energy consumption is high, and efficient is low; Can not recycle, poor processability, its low temperature brittleness temperature is-30 ℃; Resistance to low temperature is undesirable, and owing to additive can not arbitrarily add, and keep away unavoidable sulfuring up; Influence surface behind the sulfuring up, the surface property of this thermoset rubber is poor, does not reach hydrophobic requirement; The complete processing of PVC is simple, and efficient is high, and processing characteristics is preferable; The vicat softening point temperature of PVC is 80 ℃, and the low temperature brittleness temperature is merely-10 ℃, and is high temperature resistant all undesirable with resistance to low temperature; Aspect surface property, PVC is the polarity material, and it is water-soluble that ester plasticizer is prone to migration; Rainwater has hydrogen bond action to the surface, can't be hydrophobic by force, and surface property is relatively poor; The complete processing of general SEBS is simple, and efficient is high, and processing characteristics is preferable, and its vicat softening point temperature is 80 ℃, and the low temperature brittleness temperature is-45 ℃, and it is high temperature resistant, resistance to low temperature is all undesirable, and its surface property also need carry out modification.PVC causes the electric property of cable and environmental resistance to reduce also easily because of various environmental factors age hardenings.Therefore need the material of existing cable sheath tube be improved.
Summary of the invention
An object of the present invention is to provide a kind of thermoplastic elastomer, to overcome existing cable sheath tube because the defective of poor, resistance to low temperature difference of Drawing abillity and surface property difference.
Thermoplastic elastomer, mainly process by the feed composition of following weight part:
