Description
Technical field
The present invention relates to a kind of elevator controllings to be servo-actuated cable, in particular to flexible fire resisting is servo-actuated cable.
Background technique
Our overall national strength and the living standard of the people have a large increase at present, especially building trade in recent years
It has developed rapidly, the living conditions of city dweller are greatly improved；On the other hand, the fundamental realities of the country that China has a large population and a few land is one
Objective reality, it promotes urban architecture that must develop to high level, these factors have just driven the increasing of the dosage of building trade elevator
Add.There is to resident and lives band supplied materials great convenience in the use of elevator, while elevator safety use also just seems more important.
Elevator controlling is servo-actuated transport vehicle of the cable as elevator control signals, since its Special use place and Special use are wanted
It asks, its reliability and safety are just used concerning entire elevator safety.
It is exhausted for copper core polyvinyl chloride that the elevator controlling that China's elevator industry uses at this stage is servo-actuated most of its model of cable
The sheath material of edge pvc sheath flat cable, the cable is thermoplastic polyvinyl chloride's elastic material, although the material has
Preferable elasticity and flexibility, but the material is in being granulated processing, it is necessary to add the weight skill element compound such as lead salt
As stabilizer, it is necessary to use the organic compounds such as polybrominated biphenyls (ether) as plasticizer.A large amount of use meetings that these materials are taken
Make these cables after service life is scrapped, cable waste processing can cause environment seriously to pollute；And this model cable
It is come into operation in elevator or, the toxic gases such as halogen, people can be contained in the gas of burning in event of fire
Body will lead to death by suffocation within a very short time after sucking these toxic gases, reduce personnel escape's chance in material fire.Separately
Outside, due to that can cause to corrode to building, equipment, instrument etc. containing corrosive gas such as halogens, fire quadratic loss is generated.
Be servo-actuated these disadvantages of cable for polyvinyl chloride-insulated polyvinyl chloride flat elevator controlling, at present it is external
A kind of servo-actuated cable of low smoke halogen-free elevator controlling is developed, which has fire-retardant Halogen low toxicity and without a huge sum of money
The features such as belonging to element and polybrominated biphenyls (ether) has smoke amount few, it is toxic to be practically free of halogen etc. in the case where meeting with fire
Gas, cable recycle in the future and scrap processing conveniently, will not cause secondary pollution to environment.
But these low smoke halogen-free elevator controllings are servo-actuated cable, at present by good using overall situation, but user
There are some problems for reflection: 1, cable sheath material is hard, elasticity is bad, and bending property is poor；2, the cable test life that circumnutates is short；3,
Fire resistance is undesirable.
In order to improve the above problem that low smoke halogen-free elevator controlling is servo-actuated cable, there is one kind with ethyl vinyl acetate second
LSOH anti-flaming environment-friendly elevator controlling based on alkene copolymer and ethylene-octene copolymer is servo-actuated cable jacket material, but
It is its fire resistance or not good enough.
Summary of the invention
Technical problem to be solved by the present invention lies in for the servo-actuated electricity of existing LSOH anti-flaming environment-friendly elevator controlling
The not high problem of fire resistance present in cable protective cover material and a kind of flexible fire resisting is provided and is servo-actuated cable, to improve its fire resistance.
The technical problems to be solved by the invention can be achieved through the following technical solutions:
Flexible fire resisting is servo-actuated cable, which is characterized in that including several conductive cable cores arranged in parallel and is extruded in several flat
Row arrangement conductive cable core on ceramic silica gel sheath, the sheath phase-change material on the ceramic silica gel sheath every
The torrid zone, the ceramic silica gel outer jacket being extruded on the sheath phase-change material heat insulating belt；Each conductive cable core by 6 class conductors and around
Wrap on the 6 class conductor fire-resistant isinglass belt, the first layer ceramic silica gel insulating layer that is extruded on the fireproof mica band and
Insulating layer phase-change material heat insulating belt on the ceramic silica gel insulating layer and it is extruded in the insulating layer phase-change material
Second layer ceramic silica gel insulating layer on heat insulating belt.
In a preferred embodiment of the invention, the sheath phase-change material heat insulating belt and the insulating layer phase-change material
The structure of heat insulating belt is identical, is the calcium chloride solution infiltration glass fibre yarn using high concentration, after by drying cylinder Kun, then spray 3000 mesh
CaCl2Powder it is multiple it is molded after, then cut into the width phase-change material band of needs, then be made of aluminium plastic bag vacuum packaging.
Ceramic silica gel material of the invention, which has to be generated after fire burning, reacts the characteristic for forming hard ceramics tubulose,
But the characteristic that original soft condition is presented at normal temperature uses ceramic silica gel as clad, can play heat resistant
Performance, the ceramic silica gel by fire burning after will form ceramic tubular, the electric wire wire by influence of fire can be protected
Cable does not generate short circuit, prevents fire from internally protecting the extent of damage of electric wire, while can completely cut off outside heat.
The refractory mechanism in addition, sheath phase-change material heat insulating belt of the invention and the insulating layer phase-change material heat insulating belt cool down
It is:
Calcium chloride becomes hollow little particle and plays heat insulation after being heated in flame, reheat, with vapor, titanium dioxide
Carbon, CaCl2Between react repeatedly after cool down, until gasification, the porcelain speed of the effective internal layer ceramic silica gel that is delayed, while glass
Yarn can reticulate to solidify the ceramic powder of operation fragmentation, further function as fireproofing function, core is kept to operate normally.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present invention is further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, flexibility fire resisting shown in figure is servo-actuated cable, including several conductive cable cores arranged in parallel and is extruded in
Ceramic silica gel sheath 10 in several conductive cable cores arranged in parallel, the sheath phase transformation on ceramic silica gel sheath 10
Material heat insulating belt 20, the ceramic silica gel outer jacket 30 being extruded on sheath phase-change material heat insulating belt 20.
Fire-resistant isinglass belt 50 of each conductive cable core by 6 class conductors 40 and on 6 class conductors 40 is extruded in fire resisting cloud
Ceramic silica gel insulating layer 60 on master tape 50 and the insulating layer phase-change material heat insulating belt 70 on ceramic silica gel insulating layer 60
And it is extruded in the ceramic silica gel insulating layer 80 on insulating layer phase-change material heat insulating belt 70.
Sheath phase-change material heat insulating belt 20 is identical with the structure of insulating layer phase-change material heat insulating belt 70, is using high concentration
