Abstract
The invention discloses an LSOH (Low Smoke Zero Halogen) flame-retardant cable material which comprises the following components by weight percent: 21%-29% of EVA (Ethylene-vinyl acetate copolymer) resin, 3%-9% of PE (Poly Ethylene) grafts, 60%-70% of an inorganic flame retardant, 1%-3% of metallic oxide, 0.2%-0.5% of vinyl trimethoxy silane, 1%-3% of a lubricant, 0.1%-0.3% of EBS (Ethylene Bis Stearamide) and 0.05%-0.5% of an antioxidant. The LSOH flame-retardant cable material which is obtained by adopting the components and the ratio thereof has a good effect of low smoke flame retardancy, meets the requirement of vertical burning tests, can be used for replacing the traditional PVC (polyvinyl chloride) cable materials, and is secure.
Description
Technical field
The present invention relates to the electric material field, refer to especially a kind of low-smoke halogen-free flame-proof cable material.
Background technology
In recent years, it is found that the personnel's cause of death in fire failure is relevant with dense smoke and the toxic gas of material production more than 80%.along with developing rapidly of China's modern industry, Safety countermeasure also should be more and more perfect, at many large-scale public places, be the secondary disaster (producing a large amount of smog and sour gas during cable fire) of avoiding ignition of cable to cause, the electric wire that uses specializing in electric energy transmitting and communication signals, not only require to have when cable and surrounding environment are caught fire, has flame retardant propertiess such as to stop propagation of flame, and can keep cable and continue electric energy transmitting and communication signals, and also should have low-smoke when burning, produce gaseous corrosion low, be beneficial to the performance at staff's safe escape scene, namely should make cable have Halogen, low cigarette, the performance such as fire-retardant.
also there are at present some open about the technology of flame retardant cable, common low-smoke halogen-free cable is take the EVA(ethylene-vinyl acetate copolymer) and the PE(polyethylene) resin is base material, add inorganic combustion inhibitor, coupling agent, oxidation inhibitor, the auxiliary agents such as lubricant mix through high speed mixer, the Banbury mixer banburying, plastified by parallel double-screw again, at last in the moulding of single-screw machine extruding pelletization, and this class cable is unreasonable because of proportioning, cause flame retarding efficiency low, self-extinguishing is poor etc., can not satisfy the requirement of vertical combustion test, therefore, be badly in need of a kind of cable material with low smoke high flame retardant effect, meet the need of market.
Summary of the invention
The present invention proposes a kind of low-smoke halogen-free flame-proof cable material, has solved cable-flame retardant weak effect in prior art, and the dense problem of combustion fumes.
Technical scheme of the present invention is achieved in that a kind of low-smoke halogen-free flame-proof cable material, comprises each component of following mass percent:
Preferably, the mass percent of each component is:
Preferably, described inorganic combustion inhibitor is magnesium hydroxide, and the decomposition temperature of magnesium hydroxide is more than 340 ℃, and is eager to excel in whatever one does a lot of than other inorganic combustion inhibitors such as aluminium hydroxide etc. to the flame retardant properties that improves wire rod, can reach better flame retardant effect.
Preferably, described metal oxide is the mixture of a kind of in zinc oxide, titanium oxide or two kinds, adds the self-extinguishing that described metal oxide can improve the Halogen material in component, coordinates other flame retardance elements, plays good synergistic effect.
Preferably, described oxidation inhibitor is antioxidant 1010, i.e. four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester, described oxidation inhibitor can the inhibited oxidation effects, extends the work-ing life of described low-smoke halogen-free flame-proof cable material.
Further, described lubricant is the silicone powder.
The preparation of carrying out component according to each above-mentioned component and proportioning mixes, and by melting mixing, through the plasticizing of combined parallel twin screw, the single-screw machine extruding pelletization can obtain the finished product of described low-smoke halogen-free flame-proof cable material through wind cold drying.
beneficial effect of the present invention is: the present invention adopts described EVA resin, described PE connects a thing as base material, and add magnesium hydroxide as described inorganic combustion inhibitor, and metal oxide, reach fire-retardant effect, simultaneously, also added lubricant in described low-smoke halogen-free flame-proof cable material, EBS, oxidation inhibitor, and as other components such as vinyltrimethoxy silane of coupling agent, improved the properties of described low-smoke halogen-free flame-proof cable material, long service life etc., described low-smoke halogen-free flame-proof cable material shows on the low-smoke and flame retardant performance and is particularly splendid, can satisfy the VW-1 vertical combustion testing standard requirement in U.S. UL1518, thereby use safer, can be used for substituting traditional PVC cable material.
Embodiment
For understanding better the present invention; below by following examples, the present invention is done further concrete elaboration; but unintelligible is limitation of the invention; some nonessential improvement and adjustment for those skilled in the art does according to the foregoing invention content also are considered as dropping in protection scope of the present invention.
Each component disclosed according to the present invention and proportioning thereof, we obtain following examples:
Embodiment 1
Embodiment 2
Embodiment 3
Component in embodiment 1 to 3 and proportioning are made finished product 1,2 and 3 according to disclosed information in the present invention, then carry out the vertical combustion test, can satisfy standard-required.
We carry out performance test to implementing 1 again, obtain following test data:
Physical strength is 12.2MPA, and elongation is 185%, and oxygen index (OI) is 41.
Above experimental data explanation, this low-smoke halogen-free flame-proof cable material disclosed by the invention has excellent flame retardant effect, can satisfy the requirement of vertical combustion test, and simultaneously, other properties do well equally, can be used for replacing traditional PVC cable material.
The above is only preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
