Abstract
The invention discloses a high-flame-retardance fireproof cable made of inorganic materials. The high-flame-retardance fireproof cable comprises a plurality of wire cables, a fire-resistant layer made of inorganic materials and a flame-retardant jacket. The fire-resistant layer made of the inorganic materials is extruded on the wire cables; the flame-retardant jacket is sleeved on the fire-resistant layer made of the inorganic materials; each wire cable consists of a copper conductor and a vitrified silicon rubber insulating layer extruded on the copper conductor; and a filling layer is filled in the fire-resistant layer made of the inorganic materials. The high-flame-retardance fireproof cable is characterized in that the fire-resistant layer made of the inorganic materials comprises, by weight, 85% of magnesium hydroxide, 6% of serpentine powder, 4% of magnesium calcium carbonate, 3% of sodium silicate and 2% of chlorinated paraffin which are squeezed to form the fire-resistant layer made of the inorganic materials. The insulating layer is made of vitrified silicon rubber, and because the insulating layer has high fire resistance and the vitrified silicon rubber is vitrified at a high temperature, the insulating performance of the cable is guaranteed during spontaneous combustion of the cable and external fire disasters. Besides, as the fire-resistant layer made of the inorganic materials is totally made of the inorganic materials by cold stirring and extruding, the materials cannot be combusted during the fire disasters, and flame-retardant and fireproofing effects can be achieved effectively.
Description
Technical field
The present invention relates to the fireproof cable technical field, particularly a kind of inorganic material high flame retardant fireproof cable.
Background technology
Along with the development of Macromolecular materials industry, high molecular synthetic material more and more is widely used in the fields such as building, chemical industry, military affairs and traffic, because the inflammability of macromolecular material.Therefore flame-retarded technology receives the concern in the whole world, along with various countries to the enhancing of environmental consciousness and the in succession promulgation of flame retardant regulation, the development in fire retardant market is very fast, and is particularly efficient, smoke suppressing is strong, and the mineral-type fire retardants such as nontoxic mg (oH) 2 more and more are subject to user's favor.
Magnesium hydroxide Mg (OH)
2Be inorganic combustion inhibitor, producing, use and discard in all do not contain hazardous substance, and can also in combustion process in the acidity and the corrosive gas that produce, be a kind of environment-friendly fire retardant.China is to Mg (OH)
2The development of flame-retardant system generally is the Mg (OH) that considers to add the different quality mark in flame-retardant system
2Content changes anti-flammability, hardness, processing characteristics and the chemical property of fire proofing, makes composite flame-retardant agent have efficiently, hang down cigarette, nontoxic function concurrently.
More than contain Mg (OH)
2Fire retardant all is packing types, thermal endurance, oil resistance, flexibility, the performance requirement of strength of cable are all higher now, single on the fire resistance performance, although but fire-resisting cable mg (oH) 2 fire retardants of producing with this composite material can reach cigarette, the fire-resistant effect of low cigarette reaches far away fire prevention truly, the specification requirement of safety.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of inorganic material high flame retardant fireproof cable for the existing weak point of prior art.This fireproof cable indices all reaches and surpasses the BS6387 standard-required.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of inorganic material high flame retardant fireproof cable, comprising the several wire cable and being extruded in the inorganic material flame retardant coating on the several wire cable and being enclosed within fire-retardant overcoat on the described inorganic material flame retardant coating, wherein every cable is made of copper conductor and the ceramic silicon rubber insulation that is extruded on the described copper conductor; Be filled with packed layer in described inorganic material flame retardant coating, it is characterized in that, described inorganic material flame retardant coating is that the material extruding by following percentage by weight forms:
Magnesium hydroxide: 85%, the snake stone flour: 6%, magnesium calcium carbonate: 4%, sodium metasilicate: 3%, chlorinated paraffin wax: 2%.
Owing to having adopted technical scheme as above, the present invention compared with prior art has following advantage:
1, state to include the fire retardant of magnesium oxide composition all be composite material, the material that adds other according to different grades is with performances such as the machinery that increases composite material, electric insulation, flexibilities, but this compound owing to having added other material, composite material all is not comprised of inorganic material, so, can not embody the incombustible characteristic of inorganic material.The present invention selects magnesium hydroxide, snake stone flour, magnesium calcium carbonate, sodium metasilicate, chlorinated paraffin wax.Directly fully stir (can add in right amount water depending on caking ability), through cold extrusion press the flame retardant coating that all is comprised of the inorganic material stirring is squeezed on the insulating barrier of cable, cable is played fire prevention, fire-resistant effect.
What 2, insulating layer material of the present invention was selected is ceramic silicon rubber because its good fire resistance and when running into high temperature the material ceramic, it can when cable spontaneous combustion and outside fire occur, guarantee the insulation property of cable.The inorganic material flame retardant coating owing to being to be formed by the cold stirring extrusion process of inorganic material all, occurs constantly at fire, and material itself can not burn, and can effectively reach back-fire relief and fireproof effect.The present invention can delay and stop spreading of the intensity of a fire by selecting suitable, appropriate refractory material when the outside breaking out of fire of cable, as much as possible normally move the protection safety of life and property to reach the energising circuit.The heating that causes owing to reasons such as overload, superpressures in cable self-operating process during the accidents such as spontaneous combustion, guarantees the as far as possible safe operation of time of circuit.
