Background technology
Wire cable insulating and sheath are commonly called as CABLE MATERIALS with plastics, and which includes rubber, polyvinyl chloride, polyethylene, poly-
A variety of kinds such as alkene, nylon.Existing CABLE MATERIALS is generally polyvinyl chloride and polyethylene kind high molecular material, this is a kind of easy
Combustible material.After fire occurs for ambient enviroment, flame can spread to entire circuit rapidly along cable, cause the expansion of flame.
Spot fire caused by reduce cable fire, the use of flame retardant cable are more and more common.Present flame retardant cable mainly has
Halogen is fire-retardant, when fire occurs, can generate a large amount of smog, generate hydrogen halide toxic, with irritating and corrosive.Smog
Fire fighting and evacuating personnel can be interfered, hydrogen halide meeting etching apparatus can also be detrimental to health.Produce and use low smoke and zero halogen
Flame retardant cable has become a kind of trend, and fireproofing cable material without halide is key therein.Meanwhile ensureing low cigarette, nothing
While halogen, flame retardant property, it is also necessary to ensure its mechanical performance and insulation performance.
The content of the invention
Present invention aim to provide a kind of fireproofing cable material without halide, ensureing low cigarette, Halogen, anti-flammability
While energy, it can also be ensured that mechanical performance and insulation performance.
To achieve the above object, the technical solution adopted by the present invention is：A kind of fireproofing cable material without halide, the cable
Expect that raw materials by weight portion includes following component：120 ~ 160 parts of base resin, 200 ~ 300 parts of halogen-free flame retardants, silane surfaces change
2 ~ 4 parts of agent of property, 20 ~ 35 parts of compatilizer, 2 ~ 4 parts of antioxidant.
Preferably, the base resin is mixed by ethylene-vinyl acetate copolymer, polyvinyl, polyolefin elastomer
It closes, the ethylene-vinyl acetate copolymer, polyvinyl, the weight ratio of polyolefin elastomer are 100:(10~
30):(10~30)。
Preferably, in the ethylene-vinyl acetate copolymer, vinyl acetate accounts for ethylene-vinyl acetate copolymer content
20%~28%。
Preferably, the polyvinyl is metallocene PE.
Preferably, the halogen-free flame retardants is hydroxide flame retardant and zinc borate, the hydroxide flame retardant and boron

Preferably, the flame-resistant lubricant that parts by weight are 0.5 ~ 1.5 part is further included in the CABLE MATERIALS.
It is furthermore preferred that the flame-resistant lubricant is silicone.
A kind of method for preparing above-mentioned fireproofing cable material without halide, step include：By CABLE MATERIALS raw material according to weight
After number mixing, the draw ratio of the fireproofing cable material without halide, wherein comminutor is obtained after being granulated directly in comminutor
For (48 ~ 56):1.
The prior art that above unspecified part is known using those skilled in the art is realized.
The fire retardant reaction mechanism used in the present invention is as follows：
The fire retardant mechanism of aluminium hydroxide：
The fire retardant mechanism of aluminium hydroxide is:1. aluminium hydroxide absorbs heat when passing through decomposition, to achieve the purpose that reduce polymer temperature;
2. the vapor that aluminium hydroxide discharges when decomposing can dilute the concentration of imflammable gas and oxygen;3. filling aluminium hydroxide can be with
Decline the concentration of polymer;4. the aluminium oxide that aluminium hydroxide decomposes generation is covered in the surface of polymer, therefore can completely cut off
Oxygen plays fire-retardant effect.
The fire retardant mechanism of magnesium hydroxide：
Magnesium hydroxide is all inorganic additive flame retardant as aluminium hydroxide, and moisture can be released when being thermally decomposed, and is absorbed big
The latent heat of amount can both reduce the actual temperature of the flame of material surface, slow down polymer degradation as low molecular speed, reduce
The generation of combustible, and the temperature of material surface oxygen can be watered down by the steam released, make the burning of material surface
More difficult progress.Magnesium hydroxide advantageously forms surface char, prevents the entrance of heat and oxygen.The magnesia resolved into simultaneously
Or good refractory material.So once burning things which may cause a fire disaster is destroyed, burning can voluntarily stop.
The fire retardant mechanism of zinc borate：
The fire retardation of borate is essentially from the following aspects：1. glassy state inorganic expansive coating can be formed；2. it can promote
Into charcoal；3. the effusion of volatile fuel can be hindered；4. can be dehydrated at high temperature, have and absorb heat, foam and rush dilute combustible
Effect.The fire retardant mechanism of hydration zinc borate is：When temperature is higher than 300 DEG C, zinc borate thermal decomposition releases the crystallization water, plays
The effect of oxygen in heat absorption cooling effect and diluent air.On the other hand, zinc borate decomposes generation B at high temperature2O3, it is attached to
On the surface of polymer formed one layer of coating, this coating can inhibit imflammable gas generation, can also prevent oxidation reaction and
Thermal decomposition acts on.
Fireproofing cable material without halide prepared by the present invention is ensureing the basis of CABLE MATERIALS insulation performance and mechanical performance
On, good flame retardation effect, and Halogen, burning will not harmful smokes.Also, antioxidant is added in the CABLE MATERIALS of the present invention, it can
To improve the heatproof of CABLE MATERIALS and ageing-resistant performance.Meanwhile CABLE MATERIALS of the invention need not be first by raw material in preparation process
It carries out mixing and carries out extruding pelletization after directly mixing, by increasing the draw ratio of comminutor and increasing compatilizer, silane table
Face active agent content ensures its kneading effect.Preparation method is simple, at low cost, highly practical.
