Abstract
The invention relates to a composite material for insulation and jacket of electrical wires and cables, belonging to the field of materials for insulation and jacket of electrical wires and cables, in particular to a material for insulation and jacket of polyester electrical wires and cables. The composite material comprises the following components by weight: 40-55 percent of polyvinyl chloride resin (PVC), 13-18 percent of polycarbonate, 26-32 percent of plasticizer, 5-9 percent of activated calcium carbonate, 2.5-4 percent of stabilizing agent and 0.5-1 percent of lubricant. Cables made of the composite material have excellent performance; the performances such as high-temperature, low-temperature, acid and oil durability, corrosion prevention and shock resistance are improved; the service life of the cable is prolonged; the operation is safe and reliable; loss for production and inconvenience for resident life caused by power cut or replacing cable are reduced; and the spare part expense and the running cost are reduced.
Description
Technical field
The invention belongs to the insulation and the sheath material of electric wire, relate in particular to the insulation and the sheath material of polyester electric wire.
Background technology
Electric wire is the carrier that power transmission or information are transmitted, and is widely used in industry and the civilian electricity consumption facility.Environment for use or occasion difference require different.Especially industry environments for use such as wind-power electricity generation, metallurgy and chemical industry are abominable, and cable product is proposed some specific performance properties requirements.Require low temperature resistant, the antitorque commentaries on classics of cable as wind power plant, metallurgy industry requires cable high temperature resistant, corrosion-resistant, and chemical industry requires acidproof, the oil resistant, corrosion-resistant of cable.And the PVC sheath material flexibility of current use is poor, elongation at break is little, anti-cracking performance is poor, do not possess anti-ly reverse, anti--40 ℃ of low temperature or anti-110 ℃ of pyritous performances, oil resistant, acidproof, antiseptic property do not reach requirement yet, cable is short work-ing life, changes frequently, influences industrial production and normally carries out.Have to adopt silicon rubber or polyurethane material in order to satisfy these particular requirements, to have.But the shock-resistance of silicon rubber is poor, and cable sheath ftractures easily, and work-ing life is also short, and the cost of polyurethane material is too high.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this invention is to provide a kind of wire cable insulating and sheath matrix material, the insulation and the sheath that are used for electric wire, improve the high-and low-temperature resistance, shock resistance of electric wire, acidproof, oil resistant and Corrosion Protection, increase the service life, safe and reliable to operation, reducing has a power failure or change cable causes damage and resident living inconvenience to production, reduces spare part expense and operation cost.
A kind of wire cable insulating and sheath matrix material are characterized in this material by weight percentage, and be composed of the following components:
Polyvinyl chloride (PVC) RESINS (PVC) 40%～55%
Polycarbonate 13%～18%
Softening agent 26%～32%
Treated carbonates 5%～9%
Stablizer 2.5%～4%
Lubricant 0.5%～1%
It is 100000 that described polycarbonate gets ultra high molecular-weight polycarbonate powder weight-average molecular weight by the triphosgene legal system.
The high-molecular weight polyvinyl chloride (PVC) RESINS helps improving low temperature brittleness, thermal ageing and the solvent resistance of mixture.Utilize polycarbonate to have excellent property modification mixture, improve shock-resistant, oil resistant, acidproof and performance that temperature resistant range is wide.
The used softening agent of matrix material of the present invention is the mixture of dioctyl phthalate (DOP) DOP and the dioctyl sebacate DOS that resists cold, and the ratio of both weight is 1:1, improves the snappiness under the mixture low temperature, increases the cold tolerance of mixture.
With the cable that matrix material of the present invention is made, advantage is: anti-ly reverse, shock resistance low temperature resistant reaching-40 ℃, high temperature resistant 110 ℃, oil resistant, acidproof and anti-corrosion resistance nature; The cable long service life, safe and reliable to operation, maintenance is few, reduces power failure or changes loss and the resident living inconvenience that cable causes to production, reduces spare part expense and operation cost.
