Description
Technical field
The present invention relates to a kind of wire-insulating compound and manufacture method thereof, is a kind of wire-insulating compound and manufacture method thereof of anti-electric arc specifically.
Background technology
Along with economic development, the popularity of electrical equipment is more and more higher, and the use amount of lead is also increasing.Present wire insulation layer material mainly is based on polyvinyl chloride (PVC), and adds corresponding adjuvants and make.But because thermal endurance, anti-flammability and the resistance to ag(e)ing of polyvinyl chloride are all relatively poor, thereby the useful life of lead is shorter, and fail safe and reliability are all relatively poor.And that polyvinyl chloride needs to add in the course of processing is leaded, the auxiliary agent of barium, cadmium, these auxiliary agents that contain the harmful heavy metal element lead is long-time can dissolving after using, environment is polluted.In addition, the lead that polyvinyl chloride the is made hydrogen chloride that in combustion process, can give off poisonous gas, harm people's health.Chlorinated polyethylene rubber (CPE) is used at lead, cable industry on a large scale as a kind of material of good cost performance in recent years, because at chlorinated polyethylene rubber is the chlorine-containing polymer that does not have two keys on a kind of main chain, so it has excellent chemical stability, resistance to ag(e)ing, anti-flammability and oil resistance are all better.In order to improve the anti-flammability of chlorinated polyethylene rubber lead, generally with antimonous oxide (Sb
2O
3) be the collaborative use of fire retardant and chlorinated polyethylene rubber, form halogen antimony flame-retardant system.In addition, when lead is applying when burning under the voltage condition, form carbide and generate heat owing to electric current flows through the burning back, charcoal is because heating and oxidized, generation electric spark when it disappears.Halogen antimony flame-retardant system very easily forms does not have the burning of falling into, and the carbide on top layer contains a large amount of heats, quickens charring layer formation and very easily produces electric spark, and existing technology generally is to add metal hydroxides in the chlorinated polyethylene rubber lead.Metal hydroxides in the lead is decomposes when wire combustion or generation electric arc, produces moisture, absorbs a large amount of heat, can reach the fire-retardant purpose of cancellation electric arc.But in this chlorinated polyethylene rubber lead, because of it needs to use a large amount of antimonous oxides in the course of processing, and the burning of antimonous oxide is flameless combustion, is not easy to control the cancellation of electric arc.And the cost of antimonous oxide is higher, and the production cost of lead is risen.Therefore, present chlorinated polyethylene rubber lead awaits further improvement.
Summary of the invention
Goal of the invention of the present invention is to overcome the deficiencies in the prior art, and a kind of have good anti-flammability, the wire-insulating compound of arc resistance are provided.
Another goal of the invention of the present invention provides a kind of method for preparing the said wires Insulation Material.
Goal of the invention of the present invention is achieved in that a kind of wire-insulating compound, it is characterized in that: described wire-insulating compound comprises chlorinated polyethylene rubber (CPE), fire retardant, filler, plasticizer, crosslinking coagent, vulcanizing agent and electric arc quencher, and each components contents is calculated by weight and is respectively 100 parts of chlorinated polyethylene rubbers (CPE), fire retardant 1-5 part, filler 20-80 part, plasticizer 10-30 part, crosslinking coagent 2-5 part, vulcanizing agent 2-5 part, electric arc quencher 20-50 part.
Described fire retardant is antimonous oxide (Sb
2O
3).
Described filler is that wherein one or more the above-mentioned composition of superfine talcum powder, calcium carbonate, potter's clay mixes with arbitrary proportion.
Described plasticizer is trioctyl trimellitate (TOTM) (TOTM).
Described crosslinking coagent is cyanacrylate (TAIC).

Described electric arc quencher is super fine magnesium hydroxide (MDH).
Contain activated magnesia (MgO) in the described wire-insulating compound.
The content of described activated magnesia (MgO) is figured part into 5-10 by weight.
Contain carbon black in the described wire-insulating compound.
The content of described carbon black is figured part into 2-3 by weight.
Described manufacture method may further comprise the steps:
A. in banbury, add fire retardant, crosslinking coagent and electric arc quencher successively, to be mixedly add filler and chlorinated polyethylene rubber (CPE) successively after evenly, under atmospheric pressure environment mixing 1-3 minute;
B. add plasticizer, under atmospheric pressure environment mixing 1-4 minute;
C. depress the pressure thallium, after the dnockout temperature reaches 70-80 ℃, promote and press thallium;
D. clean dust, when the dnockout temperature reaches 90-110 ℃, add vulcanizing agent;
E. continue dnockout 30-70 second after adding vulcanizing agent, expect the enterprising one-step melting of mill then down;
F. the rubber that mixes was parked under normal temperature, normal pressure 10-20 hour, treated that rubber answer normality gets final product.
The present invention has the following advantages:
1, in the wire-insulating compound of the present invention, because fire retardant antimonous oxide (Sb
2O
3) content less, significantly reduced the phenomenon of glowing of charring layer after the wire combustion, also less to the negative effect of arc resistance, so lead has good arc resistance.In addition, add electric arc quencher (super fine magnesium hydroxide (MDH)) in lead, metal hydroxides meeting decomposes produces moisture when wire combustion, absorbs a large amount of heat, plays good flame-retardant effect.And in the wire combustion process, the electric arc quencher can produce cooperative effect with fire retardant, has further strengthened the arc resistance of lead.
2, in the wire-insulating compound of the present invention, because fire retardant antimonous oxide (Sb
2O
3) content less, its cost also decreases, and can save a large amount of production costs.
Embodiment
Mainly comprise chlorinated polyethylene rubber (CPE), fire retardant, filler, plasticizer, crosslinking coagent, vulcanizing agent and electric arc quencher in the wire-insulating compound of the present invention, each components contents is calculated by weight and is respectively 100 parts of chlorinated polyethylene rubbers (CPE), fire retardant 1-5 part, filler 20-80 part, plasticizer 10-30 part, crosslinking coagent 2-5 part, vulcanizing agent 2-5 part, electric arc quencher 20-50 part.It is the product of CPE135B that chlorinated polyethylene rubber (CPE) can adopt the trade mark of AsiaSat chemical production.Fire retardant is selected antimonous oxide (Sb for use
