Description
Technical field
The present invention relates to a kind of nanometer high-temperature resistant ceramic silica gel that in silicon rubber, adds nanometer materials and form.
Background technology
In the last few years, particularly after the U.S.'s 911 events, and after the large-scale place of public amusement of domestic a few family, chemical industry, colliery, commercial building fire caused painful people's life and property heavy losses, people had had more deep understanding to fire-fighting, fire safety.How under fire condition, ensure within a certain period of time the unimpeded of electric power and communication, win to greatest extent valuable rescue time, reduce personnel's injures and deaths and the loss of lives and properties, this is that industry is always in the problem of constantly exploring.For cable, at present, what flame resistant cable adopted both at home and abroad is the flame resistant cable that magnesium oxide mineral fire-proof insulation cable and mica tape twine mostly.Magnesium oxide mineral fire-proof insulation cable needs special manufacturing and processing equipment, produce the equipment claimed import of magnesium oxide mineral fire-proof insulation cable in addition, in addition, the outer jacket of magnesium oxide mineral fire-proof insulation cable is full copper, cost is higher, aspect practical application, also be subject to restriction to a certain degree, be difficult to popularize on a large scale use, be difficult to especially promote at covil construction etc.And the flame resistant cable that mica tape twines, need in process of production multiple wraps, because the restriction of processing condition, often easily cause seam lap place defective to occur, mica tape embrittlement after burning, come off easily, also cause fire-resistant weak effect, thereby be difficult to ensure safe and smooth under fire condition of communication, electric power.
Summary of the invention
The present invention is directed to defects, purpose is to provide a kind of and has good physical and chemical performance, thermostable type, flame retardant properties, barrier property, optical property, electrical property and high-low temperature resistant, good insulation preformance, voltage breakdown is high, heat-resistance index is large, bending property is strong, snappiness is good and the Performances of Novel Nano-Porous meter level high-temperature resistant ceramic silica gel of strong anti-interference performance, asepsis environment-protecting.
Technical scheme of the present invention is: the present invention is take silicon rubber as base-material, additional nano level polymer composite filler, carbon black, constitution controller and vulcanizing agent, its ratio is: take the silicon rubber of 100 weight parts as benchmark, nano level polymer composite filler 12-18 weight part, median size 10nm-60nm, carbon black 8-12 weight part, constitution controller 0.8-1.2 weight part, vulcanizing agent 0.3-0.8 weight part.
Described nano level polymer composite filler comprises nano aluminum nitride, nano-calcium carbonate, wherein nano aluminum nitride 3-7 weight part, particle diameter 35nm-55nm, nano-calcium carbonate 9-11 weight part, particle diameter 75nm-85nm.
Preferably, described nano aluminum nitride 5 weight parts, particle diameter 45nm, nano-calcium carbonate 10 weight parts, particle diameter 80nm.
Preferably, described carbon black 10 weight parts.
Preferably, described constitution controller is the hydroxy silicon oil of 1 weight part.
Preferably, two 25 of described vulcanizing agent 0.6 weight part.
Preferably, described raw material also comprises nano silicon.
Advantage of the present invention is: nanometer high-temperature resistant ceramic silica gel of the present invention is manufactured easily, and is applied widely.Use the cable that this material makes and to be widely used in public fire protection, the demanding public arena of fire safety, can also be used for the industries such as metallurgy, iron and steel, coke, colliery, power plant, power transmission and transformation station, petrochemical industry, Nuclear power plants, aerospace.This material manufacturing process is relative with working method simple, identical with the working method of the rubber unvulcanizate of common high temperature silicon rubber, possesses well extrudability and steamed bun pressure property, can use directly that the silicone rubber wire cable machinery is extruded, baking oven for heating is vulcanized, more not need the huge input can the decrease cost without increase equipment.Electric wire with this material produce can equally with the common wiring cable carry out laying installation easily, for extensively popularizing of fireproof electric wire and cable provides precondition and basis.The characteristics such as that the high temperature resistant flame resistant cable that this novel material is made has is high temperature resistant, good insulation preformance, voltage breakdown is high, heat-resistance index is large, bending property is strong, snappiness is good, travelling performance is strong, anti-mechanical external force damage, wear-resisting wiping, oil resistant dirt, anti-electromagnetic interference performance are superior, do not fuse even apply voltage rating 3A fusible cut-out for fiery 90min with cooling 15min duration of test under flame (950-1000 ℃) condition, pilot lamp does not extinguish.
