Description
Technical field
The present invention relates to the heat-resistant fireproof PVC cables of cable manufacturing technology field, more particularly to a kind of low smoke and zero halogen
Material.
Background technology
The base-material of electric wire is mainly PVC plastic, and PVC plastic is one of five big general synthetic plastics, is the current world
On be only second to the second largest plastics variety of polyethylene.Because Corvic has good physical and mechanical properties, can be used for
Construction material, packaging material, electronic material, daily necessities etc. are produced, are widely used in industry, agricultural, building, communications and transportation,
Each field such as power telecommunication and packaging.Electric wire is industrial and agricultural production and the indispensable critical facility of the modern life, at me
Occupy very important status in state's national economy, still, PVC cable deposits potential safety hazard inflammable at high temperature at present,
Power breakdown is easily caused, causes unnecessary economic loss.Therefore, PVC cable material is modified, is people in the art
Member's technical problem urgently to be resolved hurrily.
The content of the invention
The present invention is in order to overcome the problem of inflammable under traditional PVC cable hot conditions, there is provided a kind of low smoke and zero halogen
Heat-resistant fireproof PVC cable material.
To achieve these goals, the present invention uses following technical scheme：
A kind of heat-resistant fireproof PVC cable material, the heat-resistant fireproof PVC cable material are made up of the component of following parts by weight：It is poly-
120 ~ 150 parts of vinyl chloride, 5 ~ 10 parts of magnesium alloy, 50 ~ 100 parts of fire retardant, 20 ~ 50 parts of dispersant and composite flame-proof synergist
5.2 ~ 10 parts.
The heat resistance of magnesium alloy is high, with polyvinyl chloride compound synergic, can both improve the mechanical strength of material, again may be used
To effectively improve the heat resistance of heat-resistant fireproof PVC cable material of the present invention.Add fire retardant and appropriate composite flame-proof synergistic
Agent can then greatly improve fire-retardant, the smoke suppressing of heat-resistant fireproof PVC cable material of the present invention, and security performance is high
Preferably, the fire retardant is nanometer Cu3B2O6With nanometer Cu (BO2)2One or both of.
Preferably, the composite flame-proof synergist is made up of the component of following parts by weight：2 ~ 3 parts of Organosilicon Polymers,
0.2 ~ 1 part of 0.5 ~ 1.5 part of zinc stannate, 1.5 ~ 2.5 parts of organo montmorillonite, 1 ~ 2 part of molybdenum base hydrotalcite and phosphoprotein.
The present invention breaks through traditional fire retarding synergist and selects limitation of the chemical phosphorus reagent as flame-retardant composition, from biology
Material phosphoprotein, with reference to organo montmorillonite and molybdenum base hydrotalcite, Synergistic, increase the flame retardant effect of fire retardant.Organosilicon
High polymer and zinc stannate produce synergy, and effectively fire-retardant and suppression cigarette, its dominant mechanism are：In combustion process, organosilicon is high
Polymers generates the inorganic layer of glassy state when blend burns, and promotes the generation of carbide, and formation has certain thickness isolation
Film, so as to suppress to burn.On the one hand zinc stannate can be promoted into charcoal by being crosslinked, reduce disengaging for combustible volatile；The opposing party
The tin compound of face volatilization can be used as meteoropathic reaction catalyst, CO and soot in catalysis oxidation flame, less toxic gas
Generation, be fire in survivor add chances of survival.Hydrotalcite is layered double hydroxide（LDH）, molybdenum base water
Talcum is the hydrotalcite being modified through molybdenum compound, and molybdenum base hydrotalcite layers have abundant anti-flammability species CO3 2-And the crystallization water,
In heated combustion, anti-flammability gas CO is discharged2Play a part of starvation and reduce material surface temperature.Molybdenum base water simultaneously
Talcum forms condensed phase on surface, prevents combustion front from extending.After molybdenum base hydrotalcite is thermally decomposed, the Large ratio surface of high dispersive is formed
Solid base, there is extremely strong suction-operated to sour gas caused by combustion oxidation, so as to play excellent suppression cigarette effect.Molybdenum base
Hydrotalcite has obvious fire-retardant and smoke suppressing effect as fire retarding synergist, and less addition can refer to not reducing material oxygen
Number（LOI）While, significantly improve the smoke suppressing effect of fire retardant.Montmorillonite is shown due to a large amount of inorganic ions of interlayer
The oleophobic property come, it is unfavorable for it and disperses in polymeric matrix, therefore organically-modified, change montmorillonite surface is carried out to it
It is highly polar, make to be changed into lipophile by hydrophily between cheating engaging layer, reduce its surface energy, while increase the interlamellar spacing of montmorillonite
Greatly, the chain or monomer for enabling polymer enter interlayer, so that organic group covers montmorillonite surface or inserts its interlayer, make it
Surface energy changes, and increases interlamellar spacing, it is changed into lipophile by original hydrophily, increases point of fire retarding synergist
Dissipate performance so that the chemical stability of heat-resistant fireproof PVC cable material is good, and flame-retardant smoke inhibition effect is good.
Preferably, the Organosilicon Polymers are silicones, one kind in amido silicon oil and polysiloxane polymer or
Two kinds.
Organosilicon Polymers have stable, efficient, the low cigarette of thermal oxide, nontoxic, anti-molten drop, substrate performance is influenceed it is small etc. excellent
Point, this is determined by the property for forming the silicon oxygen bond of molecular backbone, by improve molecular structure, improve relative molecular mass,
Blending etc. improves flame-retardant smoke inhibition effect, improves processing into charcoal and matrix material and mechanical property.Due to siliceous fire-retardant poly-
Compound is few, and cigarette is nontoxic, fuel value is low, flame propagation velocity is slow, while there is synergistic effect with some fire retardants.Wherein, poly- silicon
Oxygen alkane polymer is similar to interpenetrating polymer networks（IPN）Partial cross-linked mechanism and be incorporated into heat-resistant fireproof PVC cable material
In polymer architecture, the mobility of silicon additive can be limited significantly, thus make it be not to migrate to by the table of flame-retardant polymer
Face, and with polyolefin grade height those compatible.Silicones can improve processing characteristics, mechanical performance, heat resistance of base material etc., fire-retardant
The recycling effect of agent is preferable, and the machining property of heat-resistant fireproof PVC cable material is improved while flame-retarding characteristic is improved
Energy.
Preferably, the molybdenum base hydrotalcite is by hydrotalcite and ammonium octamolybdate, in molybdenum trioxide and eight molybdic acid melamines
One or more modified be made.
Preferably, the phosphoprotein is from milk, soybean, carry in the one or more in the plant roots of saponin(e and gummy
Acquisition is taken, cost is low, wide material sources, green, and resource utilization is high.
Preferably, the dispersant is the alcohol ester of hydroxyl containing active end group, bis-stearamides, monoglyceride, in oleamide
It is one or more of.
Therefore, the present invention has the advantages that：
（1）Fire-retardant and smoke suppressing effect is good, and securely and reliably, raw material sources are wide, and cost is low；
（2）Without poisonous additive, using biological material as phosphorus source, resource utilization is improved, it is more green；
（3）Heat resistance is good, has good plasticity, has broad application prospects.
