Abstract
The invention discloses a polychloroethylene cable material for torrid zone and frigid zone, which comprises the following parts: 40-70%wt polychloroethylene resin and 30-60%wt ethylene-acetic acid ethyenyl ester copolymer composition or 70-95%wt vinyl chloride and 5-30%wt maleate copolymer, 20-35%wt dioctyl sebacate and or adipate dioctyl plasticizer, 0.3-1.6%wt ultraviolet adsorbent and 0.5-2.0%wt anti-fungus agent. The temperature scale of cable material is -50+80 Deg C, which is fit for frequent transmitting utility.
Description
Technical field
The present invention relates to a kind of polyvinyl chloride cable material, especially about can adapt to the torrid zone to the frigid zone the general polyvinyl chloride cable material of full temperature band.
Background technology
Polyvinyl chloride (PVC) CABLE MATERIALS has different the requirement at the varying environment temperature condition: xeothermic band area, summer outdoor sunlight temperature up to+70 ℃～+ 80 ℃, have the intensive ultraviolet light simultaneously, thereby require the aging and thermotolerance of anti-sunlight to get well; Subtropics-humid tropical zone, except that temperature under the summer outdoor sunlight reach+60 ℃～+ 70 ℃, there was dampness in the air, the plastics bacterium of easily mildewing causes cable moisture resistance, insulativity to descend, and therefore requires to have mildew-resistant, weather protection is aging; Refrigerant latitudes: winter the outdoor lowest temperature about-50 ℃, the embrittlement temperature of soft pvc CABLE MATERIALS only be-25 ℃, PVC thermoplastic elastomer (modified rubber) embrittlement temperature also has only and is-40 ℃, thereby requirement to have low temperature not crisp firmly.Therefore use in different temperature area, need preparation to adapt to the special PVC CABLE MATERIALS of this area's temperature environment, mobile subscriber (for example geology, petroleum prospecting, army) brings very burden to needing on a large scale for this; Secondly, the existing civilian outdoor use of PVC CABLE MATERIALS also is subjected to certain limitation, and general PVC can only use in-25-+70 ℃ temperature chamber.Therefore so far as yet invention satisfy various by the torrid zone to the frigid zone full temperature band (for example outdoor temperature difference-50 ℃～+ 80 ℃), and can satisfy the general PVC CABLE MATERIALS of outdoor application.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of can adapt to the torrid zone to the frigid zone full temperature band general, to satisfy the polyvinyl chloride cable material that often shifts use.
The object of the invention realizes, the main improvement is mixture or the vinylchlorid (VC) and maleic acid ester (M) multipolymer that base-material adopts polyvinyl chloride (PVC) RESINS (PVC) and vinyl-vinyl acetate copolymer (EVA), softening agent adopts has excellent dioctyl sebacate of property at high and low temperature (DOS) and/or Octyl adipate (DOA), thereby obtain wide temperature range and weathering resistance is strong, be suitable for the polyvinyl chloride cable material of the torrid zone full temperature band use to the frigid zone.Specifically, polyvinyl chloride cable material of the present invention, substantially form by base-material, softening agent, stablizer, it is characterized in that said base-material consists of mixture or the 70-95%wt vinylchlorid and the 5-30%wt maleate copolymer of 40-70%wt polyvinyl chloride (PVC) RESINS and 30-60%wt vinyl-vinyl acetate copolymer, said softening agent is 20-35%wt (in base-material) dioctyl sebacate and/or Octyl adipate, and 0.3-1.6%wt (in base-material) UV light absorber, 0.5-2.0%wt (in base-material) mould inhibitor.
Middle-ultraviolet lamp absorption agent of the present invention can adopt the general UV light absorber of plastics, and wherein better preferential benzophenone (for example UV-P) or the triazine uv absorber of adopting allocated the back into and had better weather resistance than other UV light absorber.
Said mould inhibitor can adopt existing commercial plastics mould inhibitor too, but wherein better preferred employing Salicylanlide or solubility 8-hydroquinoline copper or phosphoric acid are mould-proof-type softening agent such as TTP, TCP.
Stablizer: can be existing polyvinyl chloride (PVC) stabilizer and usual amounts, the 4-8%wt of base-material for example, polyvinyl-chloride use alkali stablizer for example is as tribasic lead sulfate or dibasicity phthalic acid lead or dibasicity Malaysia lead plumbate and dibasic Lead Phosphite combination.
Be to increase plasticizing efficiency, can also join the small quantities of usual softening agent outward, DOP for example, chlorinated paraffin, petrolatum 50 etc.
In addition, according to environment for use, can also add (in base-material) 0.5-1.6%wt and keep away the mouse anti-termite agent, for example cycloheximide and aldrin; The 4-12%wt auxiliary stabilizer, for example Resins, epoxy or epoxy plasticizer, the hydrogenchloride that the favorable for absorption polyvinyl chloride decomposes improves the resistant to thermal aging performance of plastics, reduces the corrosion to the copper class.
Polyvinyl chloride cable material of the present invention owing to the change to base-material and softening agent, thereby improves a lot the more original resin of polyvinyl chloride cable material use temperature scope, gained CABLE MATERIALS average index parameter: volume resistance 8.7-5.5*10
12Ω cm, embrittlement temperature: more than-50 ℃, temperature classification :+80 ℃, the thermal ageing condition: 110 ± 2 ℃, 7 days (168 hours), aging back strength retention ratio 〉=75% (change rate of strength≤± 25%), aging back elongation retention rate 〉=75% (elongation change rate≤± 25%), mildew resistance: 0 grade-1 grade, weather (be subjected to Exposure to Sunlight, drench with rain, comprehensive actions such as wind, topsoil aging), 8 cycles (one-period is equivalent to outdoor 1 year).Thereby polyvinyl chloride cable material of the present invention, can in-50 ℃ of-+80 ℃ of temperature ranges, use, and can adapt to outdoor application, thereby reach in China the torrid zone to the frigid zone full temperature band general, need often to shift (military equipment, geological prospecting, measurement, open-air movable electrical appliances etc.) use thereby satisfied.
Below in conjunction with several embodiments, further specify the present invention.
