The data communication cable comprises the following components in parts by weight: 88 parts of SG3 type PVC resins, 39 parts of trioctyl trimellitate, 6 parts of a calcium-zinc stabilizer, 4 parts of antimony trioxide, 0.2 part of polyethylene wax, 0.3 part of stearic acid, 0.1 part of an antioxidant and 16 parts of a water-resistant modifying agent. The antioxidant is selected from one or more of a phenolic antioxidant, an amine antioxidant, a sulfur antioxidant and a phosphite antioxidant. The data communication cable can adapt to complex use environment, can be water-resistant for a long term, and maintains excellent electrical insulation properties, mechanical properties and fire retardance.
Description
Technical field
The present invention relates to the technical field of insulated cable material, more particularly, it relates to the communication cable that a kind of anti-flammability is excellent.
Background technology
Polyvinyl chloride resin, due to the advantage having good rigidly, intensity is high, fire-retardant, corrosion-resistant, electric insulating quality is good and processing characteristics is good, cheap, has a wide range of applications in CABLE MATERIALS industry. Polyvinyl chloride cable material is mainly used in power cable, controls the sheath material of all kinds of cable such as cable, communication cable. Polyvinyl chloride cable material disclosure satisfy that the demand of insulation and sheath substantially, but it is as the continuous expansion of electric wire range of application, the performance requirement of polyvinyl chloride cable material is also more and more higher, and the water-fast and fire resistance of polyvinyl chloride cable material especially of the prior art needs to be improved further.
The outdoors cable natural environment influence owing to being exposed to the sun and rain, therefore requires higher to every physical and chemical index of the insulant used, if desired for water-fast, and insulation and high insulating property etc. in water. Polyvinyl chloride resin itself has excellent water resistance, but must add all kinds of plasticizer, stabilizer, all kinds of filler (potter's clay, calcium carbonate etc.) owing to CABLE MATERIALS produces, and inevitably reduces the immersion electrical property of product. Prior art is generally adopted high-quality plasticizer, minimizing or the mode without filler, but product index performance is still difficult to meet requirement.
Summary of the invention
In order to solve the above-mentioned technical problem existed in prior art, it is an object of the invention to provide the communication cable that a kind of anti-flammability is excellent, this material can adapt to the use environment of complexity, it is possible to water-fast for a long time, and keeps excellent electrical insulation capability, mechanical property and fire resistance. In order to solve above-mentioned technical problem and realize above-mentioned purpose, the present invention adopts the following technical scheme that: the communication cable that a kind of anti-flammability is excellent, component including following weight portion: SG3 type polyvinyl chloride resin 88 parts, trioctyl trimellitate (TOTM) 39 parts, calcium zinc stabilizer 6 parts, antimony oxide 4 parts, Tissuemat E 0.2 part, stearic acid: 0.3 part, antioxidant: 0.1 part, water-fast modifying agent: 16 parts, described antioxidant is selected from one or more in phenolic antioxidant, amine antioxidants, sulfur type antioxidant and phosphite ester kind antioxidant.
In such scheme, described water-fast modifying agent is formed through silane coupler cladding process by nano barium sulfate, calcined kaolin and nano silicon, described water-fast modifying agent includes nano barium sulfate 2 parts, calcined kaolin 7.5 parts, nano silicon 2 parts, 0.5 part of silane coupler silane, described silane coupler silane is vinyl three ('beta '-methoxy ethyoxyl) silane
Owing to technique scheme is used, the present invention compared with prior art has the advantage that 1. present invention are to carrying out Surface coating process after powder predrainage, improves the hydrophobic performance of product, and then product can be used for a long time in wet environment.2. mechanical stability of the present invention is good, and electric property is stable. 3. the water-fast modifier material in the communication cable that anti-flammability of the present invention is excellent selects nanoscale raw material, improve the compactness of product, together with the stabilizer of application, wet environment has water resistant ageing properties and water resistant tree Forming ability, further increases stability and the life cycle of product.
Detailed description of the inventionBelow in conjunction with specific embodiment, technical scheme is further elaborated, but embodiments of the present invention are not limited to this. Data cable waterproof flame retardant PVC cable material in described detailed description of the invention, component including following weight portion: SG3 type polyvinyl chloride resin 88 parts, trioctyl trimellitate (TOTM) 39 parts, calcium zinc stabilizer 6 parts, antimony oxide 4 parts, Tissuemat E 0.2 part, stearic acid: 0.3 part, antioxidant: 0.1 part, water-fast modifying agent: 16 parts, described antioxidant is selected from one or more in phenolic antioxidant, amine antioxidants, sulfur type antioxidant and phosphite ester kind antioxidant.
Water-fast modifying agent is formed through silane coupler cladding process by nano barium sulfate, calcined kaolin and nano silicon, described water-fast modifying agent includes nano barium sulfate 2 parts, calcined kaolin 7.5 parts, nano silicon 2 parts, 0.5 part of silane coupler silane, described silane coupler silane is vinyl three ('beta '-methoxy ethyoxyl) silane.
SG3 type polyvinyl chloride resin: 100 parts, TOTM:35 part, commercially available calcium zinc stabilizer: 5 parts, antimony oxide: 8 parts, Tissuemat E: 0.3 part, stearic acid: 0.2 part, bisphenol-A: 0.2 part, water-fast modifying agent: 12 parts of (wherein nano barium sulfate: 2 parts, calcined kaolins: 7.5 parts, nano silicon: 2 parts, vinyl three ('beta '-methoxy ethyoxyl) silane: 0.5 part). CABLE MATERIALS makes electric wire through detection, and the physical property obtained is as follows. Water resistance test adopts " ASTMD2219-02 electric wire and cable pvc material specification " 5.5 experimental conditions (electric current 60Hz frequency, temperature of soaking: 50 ± 1 DEG C). (1), 1-14d change in dielectric constant rate be 2.7%, 7-14d change in dielectric constant rate is 0.5%, test result analysis: the accelerated water absorption test of product, change in dielectric constant rate much smaller than standard (1-14d, 10%; 7-14d, 5%) requirement, product has good water resistance. (2), specific insulation (GB/T1410-2006) ohm meter 1013, A: water inlet front volume resistivity is 2.8*1013; B: after immersion 1d, specific insulation is 2.7*1013; C: after immersion 14d, specific insulation is 2.4*1013. Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.
