Volume resistivity and congo red heat stable time of the PVC plastic are improved by employing high-insulation and high-congo red type calcium zinc composite stabilizer DA-970. The PVC plastic fits the environmental requirements of an ROHS standard; the performance meets the J-70 index requirements of a GB/T-2008 standard of plasticized polyvinyl chloride (PVC) compounds for the wires and cables.
Description
Technical field
The present invention relates to the insulation-grade soft pvc plastics that a kind of cable is used, particularly electric wire is with 70 ℃ of insulation-grade environment-friendly type soft pvc plastics.
Background technology
In the insulation and sheath material of electric wire, PVC is more cheap, and mechanical property is good, and is easy to process, so that it becomes the maximum material of wires and cables industry usage quantity for a long time.Since 20 end of the centurys, the environmental problem of PVC material extensively is familiar with, and some developed countries have proposed restriction or completely forbidden the decree suggestion of using the PVC cable.Have data to show, the Western European countries are at the consumption of cable field PVC, and 1994 is 441kt, the line is busy 58% of the used resin of cable, and 2000, PVC is 398kt at the total consumption of West Europe cable industry, the line is busy 48% of the used resin of cable, total amount and proportion are all on a declining curve.In recent years, control and ban use of the PVC material to form strong trend.
Although replace the cry of PVC material with the Halogen material more and more higher, but PVC itself has the advantage that also can't replace in a short time (as cheap, good flame resistance, processing units, technique are simple, the hardness variable range is wide, electrical insulating property is good, oil resistant, chemical-resistant reagent etc.), so the use of short-term internal world scope total ban PVC and unrealistic.
In China, PVC CABLE MATERIALS development early, kind, model are more.In the recent period, because the raising that Environmental Protection in China requires, the development of China PVC CABLE MATERIALS is also on a declining curve gradually.But because the PVC CABLE MATERIALS is cheap, the in addition multiple advantage such as mechanical property excellence is so that China PVC CABLE MATERIALS still has certain development prospect in the recent period.At present, although also can not eliminate the PVC electric wire abroad at once, this must cause the great attention of domestic wires and cables industry, domesticly should pay attention to studying non-leaded PVC or the not halogen-containing environment-friendly type electric wire of development of new.Although the environment-friendly type electric wire replaces the PVC cable also to want considerable time at home on a large scale, this is trend of the times.More domestic high-grade projects have proposed requirement to this.
The patent disclosure of publication number CN101377967A " a kind of novel environment protection PVC cable sheath material " a kind of environment protection PVC cable sheath material that uses common calcium zinc stabilizer, its volume specific resistance requires low, reduces although realized the environmental protection insulating property; The patent disclosure of publication number CN101230171A " high electric-property high temperature resistant wearable environment protection plastic insulating material " use the insulating material of common calcium zinc stabilizer, high temperature plasticization agent and water-ground limestone, but use its volume specific resistance of common calcium zinc stabilizer do not reach requirement yet, use its cost of high temperature plasticization agent high, use water-ground limestone its than great.
