Description
Technical field
The invention belongs to cable machinery technical field more particularly to a kind of cables of fire-retardant fireproof.
Background technique
Currently, needs of the people to fast transfer of data, information, to computer, word processor, fax, sensor and
The dependence of communication equipment significantly rapidly increases.The appearance of new technology is so that online become with networking of the equipment of this respect can
Can, result in the comprehensive development of communication system.These systems increase in the use of specific area, such as skyscraper, and ship flies
Machine, train, drilling platforms and mine.In order to connect these electronic components, need in these structures and field using a large amount of
Electric wire and cable.Typically, wire and cable is installed in air handling system and wire and cable pipeline is easily to apply.By
Be in air-conditioning and wire and cable pipeline it is continuous by these devices, insulation and the safety of sheath material are basic demands, i.e.,
It is required that these materials have low flame propagation and cigarette to form speed, and different physics is executed under the conditions of various adverse environments
Performance.
The insulating layer and restrictive coating of current heatproof flame-retardant cable are usually that single fire retardant is mixed system with CABLE MATERIALS
At.The fire retardant largely used is an ancient small-mouthed wine vessel element based flame retardant, generates a large amount of smog and poisonous gas when having not flame-retarding power, but burning,
Its amount increases with ignition temperature and is increased, therefore is only used for low-temperature flame retardant.Recently used halogen-free flame-retardant smog is few, toxicity
It is small or nontoxic, but containing a large amount of hydration substances, since dehydration reduces physics, the mechanical performance of cable, institute when temperature is high
It can not be high with resistance combustion temperature.In short, due to using single fire proofing, cable is not to generate a large amount of smog and toxic gas
Cable performance is exactly reduced because of dehydration, to influence the resistance combustion temperature and duration of fire resistance of cable.It is well known that in China
Since rainwater is more, cable duct or cable tunnel are easier by rain drop erosion humidity for southern area, and in traditional cable duct
The products such as the inorganic putty of used fire-proof sealing material or fire retardant package, after rain drop erosion, moisture-sensitive deformation, stability
Can it is poor, back-fire relief effective performance is severely impacted, it is difficult to achieve the effect that it is fire-retardant, prevent fires, it is moisture-proof.
Due to having formulated more stringent fire safety standard, wire cable insulating material needs to improve its burning and hair
Bright performance, while excellent physical property is kept, need to improve its fire for low expense wire cable insulating material compositions
Flame is propagated and smoke generation characteristics, while to have excellent physical property.
Fire often occurs because of artificial origin or natural calamity among social production life, to the life of the people
Life property, which causes immeasurable loss, especially electrical equipment, and wire and cable is even more becomes main fire source, line
Short out road not only to electrical equipment generate directly damage and also be easy initiation fire, in a fire caused by line short but will add
The sprawling of the fast intensity of a fire.The usually not fire-proof of cable currently on the market or the safeguard measure of anti-short circuit generally use plastic cement
Protective layer of the equal combustibles as cable, this be easy so that adjacent cable heated and it is glutinous together, cause short circuit and damage use
Electric equipment causes fire, and when fire has occurred, this cable but will accelerate the sprawling of the intensity of a fire.
China Patent Publication No. is CN203931594U, invention and created name be it is a kind of can positive fire protection cable, can
The cable of positive fire protection includes electric conductor, glass fibre wrapping layer, low melting point glass powder layer, thin wire winding layer and Ke Tao
Porcelain plastic material layer, glass fibre wrapping layer wrap up electric conductor, and low melting point glass powder layer wraps up glass fibre wrapping layer, carefully
Conducting wire winding layer is closely wound for thin wire and rearranges, and thin wire winding layer wraps up low melting point glass powder layer, can ceramic
Plastic material layer wraps up thin wire winding layer.But existing cable is there is also fire retardant effect is poor, the conductive effect of cable
The problem of fruit difference and wiring inconvenience.
