Description
Technical field
The present invention relates to a kind of fire-resistant cable material, belong to cable material technical field.
Background technology
Flame retardant cable, refers to that the sizing material without surrounding materials such as halogen, not leaded cadmium chromium mercury is made, will not be sent during burning
The environment-friendly cable of toxic smog, it is adaptable to skyscraper, market, theater, power station, chemical plant, city square and other
The occasion high to cable-flame retardant characteristic requirements such as public utilities.The low smoke, zero halogen of cable, low smoke and low halogen characteristic, when fire occurs
When, rate of propagation is slow, and smoke density is low, it is seen that degree is high, and pernicious gas burst size is small, is easy to personnel to withdraw.The corrosion of burning gases
Property is small, it also avoid the infringement to instrument and equipment, low halogen, the characteristic of Halogen so that cable material is in ageing-resistant and UV resistant
And other irradiation behaviours are greatly improved, so as to extend the service life of cable.
Rubber and the main material that plastics are the insulation and sheaths for manufacturing electric wire.These materials mainly have two major classes,
One class is halogen material（Polyvinyl chloride, polytetrafluoroethylene (PTFE), neoprene, fluorubber etc.）.When fire occurs, these materials by
In burning and thermal decomposition, substantial amounts of smog can be produced and poisonous acid halide hydrogen, cause secondary to the person, equipment and instrument
Disaster, and greatly difficult very casualties can be brought to evacuating personnel and fire-fighting work.Another kind of is halogen-free material（Poly- second
Alkene, crosslinked polyethylene, polypropylene etc.）.These materials are not fire-retardant in itself, it is necessary to which fire-retardant material can just be become by adding fire retardant
Material.If the fire retardant of addition is Halogen, bittern-free flame-proof material is just obtained.In recent years China halogen-free flameproof exploitation and should
Made significant progress with aspect, have magnesium hydroxide, aluminium hydroxide, Phos system and organophosphor system etc. using more at present.
The addition of these fire retardants improves the fire resistance of halogen-free material, but be due to fire retardant and plastics compatibility it is poor, it is difficult
With dispersed in the material, so as to reduce its flame retardant effect.It would therefore be highly desirable to find, a kind of fire resistance is good and smoke suppressing effect
Good fire-resistant cable material.
The content of the invention
The technical problems to be solved by the invention are：For traditional fire-resistant cable material in preparation process, fire retardant and help
Agent is poor with Compatibility in Plastics, it is difficult to dispersed in CABLE MATERIALS, and causing the problem of fire-retardant and smoke suppressing effect is poor, there is provided one
Plant fire-resistant cable material.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of fire-resistant cable material, it is characterised in that：Including following component, each component is calculated by weight as：8~10 parts of modifications are multiple
Close nano-meter flame retardantses, 3~5 parts of stabilizers, 4~6 parts of Tissuemat Es, 0.2~0.4 part of antioxidant and 80~100 parts of polymer
Resin.
Described modification composite Nano fire retardant is the stearic acid of the magnesium hydroxide and aluminium hydroxide that have adsorbed precipitation generation.
Described stabilizer is to be obtained by epoxide modified oleic acid with calcium hydroxide and zinc oxide reaction.
Described antioxidant is one kind in antioxidant 1076, antioxidant 1010 or antioxidant 1178.
Described fluoropolymer resin is LLDPE.
The present invention is compared with other method, and advantageous effects are：
（1）Odium stearate is dispersed in water by the present invention first, the hydroxide ion produced using odium stearate and hydrolysis of urea
Reacted with magnesium ion in solution and aluminium ion, slow to combine generation magnesium hydroxide and aluminum hydroxide crystals, the crystal of generation is hard
The stearic acid absorption that the hydrolysis of resin acid sodium is produced, hydrolysis and adsorption process are carried out simultaneously, coordinate the sky of Long carbon chain in stearic acid molecule
Between steric hindrance, be prevented effectively from the crystal to be formed and further grow up and reunite, stearic acid and magnesium hydroxide, aluminium hydroxide is reached uniformly
Mixing, added in product, because of the presence of stearic acid components, can effectively improve fire retardant compatible with organic polymer CABLE MATERIALS
Property, so fire retardant can be uniform and stable scattered in CABLE MATERIALS, during fire-retardant, nano-particle can thermally equivalent, shape everywhere
Into high-density flame-proof layer, with excellent fire-retardant and smoke suppressing effect；
（2）The present invention utilizes the epoxide modified oleic acid of hydrogen peroxide, reacts, is made as electricity with calcium hydroxide and zinc oxide after separation
The dry cake of cable material stabilizer composition, coordinates the use of antioxidant, effectively improves the stability of product in use,
And whole formula is not added with halogen containing flame-retardant, poisonous acid halide gas will not be always discharged in fire-retardant process, it is to avoid give people
Body, equipment and instrument cause secondary disaster.
