The cable integrates the environment-friendly performances such as low smoke, halogen-free, fireproofing and the like, and the good and stable signal transmission functions.
Description
Technical field:
The utility model relates to a kind of cable, specifically a kind of high temperature resistant refractory silicone rubber for cable.
Background technology:
At present in industries such as the signal transmission of the distributing system of industrial and mining enterprises such as electric power, metallurgy, chemical industry, military enforcements and detecting instrument, instrument, adopt traditional flame-proof polyethylene insulate flame-proof polyvinyl chloride jacketed cable and common silicone rubber for cable basically.Flame-proof polyethylene insulation flame-proof polyvinyl chloride jacketed cable heatproof is 105 ℃, and common silicone rubber for cable is high temperature resistant to be merely 200 ℃.When fire took place, cable was burnt immediately, has the amount of being fuming height; There is the poisonous corrosive gas of halogen to disengage; Be unfavorable for personnel's the carrying out of evacuation, rescue work like this, and, trapped personnel and precision equipment caused " secondary disaster " owing to there is the corrosive gas of halogen to disengage.The easy fusion of residue after its burning simultaneously, drippage forms short circuit phenomenon.
Summary of the invention:
For overcoming the defective of prior art, the purpose of the utility model is to provide a kind of high temperature resistant refractory silicone rubber for cable, is the cable that a kind of signal transfer functions that will hang down environmental-protecting performances such as cigarette, Halogen, fire prevention and favorable and stable is integrated in one.
The utility model technical solution problem adopts following technical scheme:
A kind of high temperature resistant refractory silicone rubber for cable; Outside the insulated wire cores of cable, be coated with the mica tape that blocks water, polyester belt, copper wire successively and weave total screen, belting layer and external sheath layer; Said insulated wire cores is made up of conductor, wrapped mica tape and insulating barrier on said conductor; The stranded stranding of many insulated core, the cable core gap is provided with packed layer, and said insulating barrier and external sheath layer adopt potteryization silicon rubber to extrude formation.
The design feature of the utility model also is:
Said packed layer adopts low smoke, zero halogen glass rope to fill and forms.
Said belting layer adopts the wrapped formation of LSOH anti-flaming glass fibre belt.
Compared with present technology, the beneficial effect of the utility model is embodied in:
The insulating barrier of the utility model cable and external sheath layer are the ceramic-like duricrust; Duricrust not fusion under fire (650～1300 ℃) environment is not dripped, and ensures unimpeded in the situation line of fire; Play firm protective effect, the great bodily injury that when reducing fire and taking place personnel or equipment is caused.
Wrapped mica tape on the conductor of cable; Insulating layer material adopts enviroment protective ceramic silicon rubber insulation material; This material is that the HTV raw-silastic continuously is that base material adds white carbon black, silicone oil, antistructurizing agent and other auxiliary agent; Mixing through vacuum kneader, in mill, add the ep-type material that vulcanizer is processed.This material is compared with common polythene, and electric property is more or less the same, and guarantees that cable has stable signal transfer functions.Nontoxic at normal temperatures, tasteless, have good flexibility and elasticity, possess the characteristic of silicon rubber; Under flame ablation, burning promptly begins to sinter into hard ceramic-like housing behind 2～4min, and the isolation layer of this hard ceramic-like housing can very effectively stop burning away of flame; And, after burning 2～4min, giving up smoking fully, in ensuing ablation process, itself no longer include smog and produce; The smog that in the 2～4min in early stage, produces also is Halogen, nontoxic.Burning produces because smog mainly is organosilicon, and organosilicon itself does not contain poisonous harmful substance.The external sheath layer of cable adopts environment-friendly ceramic silicone rubber jacket material.This material has taken into full account the Halogen of cable, low cigarette, fire resistance, adopts novel high polymer potteryization silicon rubber composite material, to personnel and equipment do not have illeffects on every side.The auxiliary packing material of cable and band material are to adopt halogen-free flameproof glass fiber material, not only have good flame retardant property, and all are not halogen-containing environment-friendly materials.The utility model provides a kind of have high fire-resistant, Halogen, low cigarette environmental-protecting performance, has stable signal transfer functions simultaneously.The fire resistance of cable reaches the bunchy category-A burning test of GB/T18380 regulation; The low smoke performance of cable is according to the experimental condition of GB/T17651 regulation; Its light transmittance is not less than 60%; The Halogen performance of cable is according to the experimental condition of GB/T17650, and pH value is greater than 5.1, and conductivity is less than 1.2 μ s/mm.Hydrogen halide content 0.59mg/g.In a word, the utility model product is the new product that a kind of signal transfer functions that will hang down environmental-protecting performances such as cigarette, Halogen, fire prevention and favorable and stable is integrated in one, and has vast market prospect.
