Abstract
The present invention is by conductor wire core, organosilicon fire prevention mica tape, and the insulating barrier of heatproof flame-retardant CABLE MATERIALS system, restrictive coating are formed.The fire-retardant heatproof prescription of CABLE MATERIALS is made up of multiple fire-retardant and heatproof raw material, and direct and vistanex combines together, aggregates into new polyolefin polymer, so its structure is tight, electric, mechanical and physical performance is good, has good heat-resistant fireproof especially.Be suitable for indoor communications, special occasions such as skyscraper, mine, subway, boats and ships, nuclear power station.
Description
The present invention is relevant with essential electronic element, and is especially relevant with heatproof flame-retardant electric wire and telecommunication cable.
The insulating barrier of present heatproof flame-retardant cable and restrictive coating generally are that single fire retardant and CABLE MATERIALS are mixed and made into.A large amount of fire retardants that use have not flame-retarding power as the plain based flame retardant of an ancient small-mouthed wine vessel, but generate a large amount of smog and poisonous gas during burning, and it is measured with ignition temperature and increases and increase, so can only be used for low-temperature flame retardant.Recently the halogen-free flame-retardant smog of Shi Yonging is few, and toxicity is little or nontoxic, but contains a large amount of hydration materials, has reduced physics, the mechanical performance of cable when temperature is high owing to dehydration, so resistance combustion temperature can not be high.In a word, owing to use single fire proofing, cable is not that a large amount of smog of generation and toxic gas are exactly because of dehydration reduces cable performance, thereby influences the resistance combustion temperature and the duration of fire resistance of cable.
The purpose of this invention is to provide a kind of can heatproof in addition high temperature resistant have again excellent flame retardancy can, physics, the cable that is exclusively used in the high occasion of safety requirements that mechanical performance is good.
The present invention is by conductor wire core, insulating barrier, and restrictive coating is formed.Cable core is outer can wrapped organosilicon fire prevention mica tape; The organosilicon mica tape is with organosilicon mica powder to be bonded on the glass fibre silk ribbon to make, and manufacturer is a Sichuan Chuan Xi mica factory.Insulating barrier, the flame-proof material of restrictive coating connect the certain proportion proportioning by fire retardant matter more than ten kinds and form.Different fire retardant matters and different proportion are made into the prescription of different resistance combustion temperatures and purposes.90-200 part composite flame-proof material and 100 parts of vistanexes directly aggregate into the fire-retardant temperature insulation layer and the restrictive coating material of different resistance combustion temperatures and purposes.The flame retardant combination composition formula of Speical flame retardant cable material can be divided into heatproof prescription and high temperature resistant prescription.
The heatproof flame-retardant prescription mainly is made up of multiple heatproof acid fat and other fire retardant matter.Be divided into 105 ℃, 135 ℃, three series of 365 ℃ of heatproof flame-retardants, fill a prescription to as follows:

The present invention has unique multi-level fire-retardant characteristics, and has guaranteed the various premium properties of cable.Oversheath of the present invention itself is fire-retardant, guarantees flame not to inner Wen Yan, the wrapped mica tape ignition temperature height in middle level, prolongs in the combustion process and does not burn, and can play heat-blocking action.Insulating barrier is fire resistant also.Cable core is subjected to triple protection.
Insulating barrier of the present invention and restrictive coating heat-resistant fireproof effect are that choose reasonable and the proportioning owing to fire proofing realizes.Present a large amount of halogen fire retardants that adopt are to suppress exothermic reaction and the oxygen supply of halogen class non-ignitibility gas partition that free OH causes according to the halogen system of making, to reach fire-retardant purpose.Advantage is that flame-retarding power is not good, does not influence cable performance; Shortcoming is that the amount of being fuming is big, and it is poisonous and be corrosive to discharge a large amount of gases.High more its shortcoming of ignition temperature is remarkable more, can not do the high temperature flame-proof agent.
The non-halogen fire retardant of bringing into use now is by the dehydration endothermic reaction of a large amount of metal hydrates of filling and uses the higher heat resistant polymer of decomposition temperature, generates to suppress inflammable substance, reaches fire-retardant purpose.Advantage is high temperature resistant, and ignition temperature is higher, and fire resistance period is long, and the amount of being fuming is few, and poisonous gas is atomic, and shortcoming is that electric property is descended, and flame-retarding power is not poor.For guaranteeing electric property, its resistance combustion temperature can not be too high.
High temperature flame-proof cable prescription of the present invention mainly selects for use in the halogen-free flameproof thing multiple dehydration temperature low, caloric receptivity is big, suppress the material that ignition temperature rises, ignition temperature is high, selected low cigarette in the fire-retardant materials of a small amount of halogen, low toxicity, the high not material of flame-retarding power on the one hand again for use.Well utilize the advantage of two class flame-proof materials and avoided its weak point.These materials connect Insulation Material and the protective cover material that certain ratio formula combination and vistanex directly aggregate into cable through overtesting.When catching fire, two kinds of fire retardations produce simultaneously to reach fire-retardant purpose.
Flame retardant insulation material of the present invention and protective cover material, physics, mechanical performance and heatproof flame-retardant performance with good CABLE MATERIALS.The hot strength of heatproof flame-retardant material, elongation at break impacts brittle temperature, 200 ℃ of heat-stable times, specific insulation, performance index such as dielectric strength all are better than international standard and national standard.Heat-resistant fireproof prescription is according to the IEC code test, in mechanical performance, and ageing properties, resistance to low temperature, insulation resistance, the darkness of smog, the damage by fume index, poison exponent, performance index such as the acid number of smog all reach or are better than the IEC standard.The test that finished cable is carried out shows: finished cable checked to the bonding degree of different parts that the result was good after wearing out in 100 ℃ * 7 days.3500 volts of 5 minutes dielectric strength passed examinations ,-15 ℃ of low-temperature bendings and shock test are excellent.According to NFC32070(or IEC332-1) carry out frame propagation test, show to have high flame retardant.Carrying out noninflammability can test, and noninflammability reaches 3.5 hours more than 840 ℃, 3-5 fray-out of flame second.Production of the present invention need not increase new in addition equipment and change production operation process and step, need only make suitable process modification.Realize easily producing in enormous quantities.Product cost is low.Product price of the present invention is estimated to exceed one to two times than common same specification cable price.Abroad this series products then generally exceeds four times of common cables.The present invention includes various building private cables, power cable and telecommunication cable can be widely used in skyscraper, blast furnace, subway, mine, private cables such as computer, power distribution room, fire alarm, intracity communication, satellite communication.
