Abstract
The invention relates to a P3 type low-smoke zero-halogen plastic coated metal hose and a manufacture process thereof. The P3 type low-smoke zero-halogen plastic coated metal hose is characterized in that an inner layer of the P3 type low-smoke zero-halogen plastic coated metal hose is provided with a P3 type galvanized metal hose, and a layer of zero-halogen low-smoke flame-retarding polyolefin materials are wrapped outside the P3 type galvanized metal hose in vacuum mode. The manufacture process of the P3 type low-smoke zero-halogen plastic coated metal hose includes a P3 type metal hose manufacture stage, a laminating stage and a product finishing stage. By adopting and using the P3 type low-smoke zero-halogen plastic coated metal hose manufactured with the manufacture process, fire hazards can be prevented and harm on human bodies after combustion happens in the fire hazards can be reduced due to the fact that the P3 type low-smoke zero-halogen plastic coated metal hose is low-smoke and non-toxic.
Description
[technical field]
The present invention relates to the protection of External cable such as a kind of cable and use flexible pipe, particularly a kind of P3 type low smoke and zero halogen plastic coated metal hose and manufacture craft thereof.
[background technology]
As everyone knows, cable place installation environments such as subway, city are underground, city building are abominable especially, and make easily As time goes on that cable is aging, oxidation etc. causes cable to destroy.So people can connect a kind of protection flexible pipe in the cable outer cover usually, like this cable and outside environment separation of living in are opened, to reach the purpose of protection cable.When flexible pipe was applied in the modern building breaking out of fire, flare high temperature made the cable burning, because the cable flexible pipe adopts the PPC material in its top layer usually in the prior art, this material is inflammable, can produce a large amount of toxic gases after the burning.Breaking out of fire escape time part is not owing to receive to burn dead or burn in building, and greatly part is owing to suck toxic gas such as volume of smoke and cause dead or the escape ability of scattering and disappearing causes death.
[summary of the invention]
For solving above deficiency; The present invention provides a kind of P3 type low smoke and zero halogen plastic coated metal hose and manufacture craft thereof, is that a kind of low-smoke and flame retardant gathers the hydrocarbon material through the P3 type low smoke and zero halogen plastic coated metal hose that this manufacture craft obtained, if burning under extraneous environmental impact; It is little to contain the cigarette amount after the burning; Can not produce toxic gas, can take precautions against the aging fire that causes of cable and take place, can take precautions against fire yet the human influence.
Technical problem to be solved by this invention is: existing cable outsourcing flexible pipe is the PPC material owing to what adopt; Produce a large amount of toxic gases in fire generation after-combustion; Make and be arranged in building, particular surroundings people are poisoned to death or influence the lost escape ability of respiration capability; And extensively build for modern building, Urban Fires are taken precautions against very important.
The technical scheme that the present invention adopted is: P3 type low smoke and zero halogen plastic coated metal hose and manufacture craft thereof; P3 type low smoke and zero halogen plastic coated metal hose is characterized in that internal layer is a P3 type galvanized metal flexible hose, at P3 type galvanized metal flexible hose external vacuum coating one deck halogen-free and low-smoke flame-retardant polyolefin material; Its manufacturing process steps does,
The system P3 metal tube stage: when making P3 type galvanized metal flexible hose, require flexible pipe to reel and form by zinc-plated mild-carbon steel strip; The galvanized layer thickness of steel band is not less than 7 μ m; That zinc coat requires is even, smooth, complete, do not allow dezincify, ink speck exists; Flexible pipe does not allow to get rusty through the neutral salt experiment in two cycles, between the pitch of flexible pipe support power elasticity should flexibly and be arranged, and does not allow and blocks and serious pulling force elasticity; External buckle does not allow crackle and serious snag phenomenon in the flexible pipe, and internal diameter size is 4 millimeters-150 millimeters specifications.
The overlay film stage: use the hot laminating machine of vacuum; In the hot laminating machine of vacuum, add the halogen-free and low-smoke flame-retardant polyolefin material, temperature is controlled between 150 degree-300 degree as required, and thickness is between the 30-70S when requiring overlay film; Overlay film is evenly complete, and smooth surface does not have electric leakage or salient point.
The finished product stage: will cover the P3 type galvanized metal flexible hose cutting size as required that the halogen-free and low-smoke flame-retardant polyolefin material membrane finishes, and the test package warehouse-in is deposited.Require section neatly smooth in the time of cutting.
The employing halogen-free and low-smoke flame-retardant polyolefin material of overlay film; It is a kind of used for oil platform 125 degree irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin jacket materials for 200910052099.9 of Chinese patents are called; Its composition is base-material (EVA, va content 20%-30% among the EVA), compatilizer (maleic anhydride graft EVA), antioxidant, halogen-free flame retardants (organic silicon composite, magnesium hydroxide and aluminium hydroxide compound), lubricant (dolomol and Tissuemat E), crosslinking sensitizer (triallyl fulminuric acid fat).The whole system of this jacking is not halogen-containing nontoxic, and the amount of being fuming is low in the time of burning.
Beneficial effect of the present invention: after adopting its application of metal hose of the present invention's making, can take precautions against fire, the LSZH reduction of burning back take place to the human injury at fire.
Further understand characteristic of the present invention and technology contents for making, see embodiment of the present invention for details, yet appended execution mode is only for reference and explanation usefulness, is not to be that the present invention is limited.
