The application of cable in life is more and more extensive, in increasing Highrise buildings, using increasing cable, and common cable does not have fire resistance, once Highrise buildings or public place presence of fire, the cable of burning will produce a large amount of hazardous and noxious substances, become people's killer, the flame resistant cable that adopts mica tape to be wound around needs multiple wraps in process of production, due to the restriction of processing condition, often easily cause seam lap place to occur defect, mica tape embrittlement after burning, easily come off, cause fire-resistant weak effect, being difficult to provides safety control for people.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of flame retardant properties is good, with low cost, ratio of briquetting is high, uses the formula of safe material, i.e. a kind of formula of low-smoke halogen-free cable line sheath material.
Technical problem to be solved by this invention realizes by the following technical solutions:
A formula for low-smoke halogen-free cable line sheath material, this formula comprises EVA, PE, aluminium hydroxide, magnesium hydroxide, oxidation inhibitor, coupling agent, silicone masterbatch, lubricant, compatilizer, black masterbatch, the shared mass percent of described each component is as follows:
The shared best in quality per-cent of described each component is as follows:
The performance of described each component and effect are as follows:
EVA: i.e. ethylene-vinyl acetate copolymer, owing to having introduced Vinyl Acetate Monomer in ethylene-vinyl acetate copolymer molecular chain, thereby reduce high-crystallinity, improve snappiness, shock resistance, filler intermiscibility and heat seal performance.
PE: i.e. polyethylene, because of polyethylene nonpolarity, so there is the electrical property excellence that dielectric loss is low, dielectric strength is large.
Aluminium hydroxide: aluminium hydroxide can not only be fire-retardant as fire retardant, and can prevent from being fuming, do not produce dropping, do not produce toxic gas.
Magnesium hydroxide: magnesium hydroxide is a kind of novel filled-type fire retardant, during by decomposes, discharge in conjunction with water, absorb a large amount of latent heat, reduce synthetic materials that it the fills surface temperature in flame, there is the polymer unwinds of inhibition and produced inflammable gas is carried out to cooling effect.Decomposing the magnesium oxide generating is again good refractory materials, also can help to improve the fire resistance of synthetic materials, and the water vapour that it is emitted simultaneously also can be used as a kind of smoke suppressant.
Oxidation inhibitor: in the time that it only exists on a small quantity in polymeric system, just can delay or suppress the carrying out of polymkeric substance oxidising process, thereby stop the aging of polymkeric substance and extend its work-ing life, " anti-aging agent " is otherwise known as.
Coupling agent: in plastics compounding, improve a kind of plastics additive of the interface performance of synthetic resins and inorganic filler or strongthener.Claim again surface-modifying agent.It can reduce the viscosity of molten synthetic resin in plastic working process, improves the dispersity of weighting agent to improve processing characteristics, and then makes goods obtain good surface quality and machinery, heat and electrical property.
Silicone masterbatch: in silicone masterbatch, content of siloxane is higher, the viscosity of material is just larger, is more not easy to disperse during for plastics.The content of siloxanes and molecular weight do anti-wear agent compared with Gao Shike and use.
Lubricant: internal lubricant and polymkeric substance have good consistency, it plays a part to reduce force of cohesion between polymer molecule in polymkeric substance inside, thereby improves the internal friction heat-dissipating of plastic melt and the mobility of melt.
Compatilizer: compatilizer increases the consistency of two kinds of polymkeric substance, makes it bonding force between two kinds of polymkeric substance and increases, and forms stable structure, makes disperse phase and external phase even, i.e. compatibilized.Why compatilizer can make the polymer-compatible of two kinds of different in kinds, is because have the cause that can carry out with two kinds of polymkeric substance respectively physics or chemically combined group in its molecule.
Black masterbatch: black masterbatch is the most frequently used a kind of Masterbatch in plastic cement processing, by a high proportion of pigment or additive and thermoplastic resin, the plastic colorant forming through good distribution, its selected resin has good wet and dissemination to tinting material, and be colored material and there is good consistency.
The invention has the beneficial effects as follows: the present invention have flame retardant properties good, manufacture simple, ratio of briquetting is high, do not produce the advantages such as pollutent after calcination; improve the quality of cable sheath material; flame retardant of plastic performance, wear resisting property and ageing resistance are improved; protect the healthy of environment and people, the use of the modern life preferably.

LSZH materials are used in various applications where smoke emission and toxicity caused by burning of the materials can be a safety hazard, such as in aircraft, trains, ships, data centers, and public spaces.
LSZH materials are made from special polymers that contain no halogenated additives, which are responsible for producing smoke and toxic fumes when the material is burned. Instead, LSZH materials are formulated with fire retardant chemicals that reduce the amount of smoke and toxic gases emitted during a fire.
LSZH materials are preferred in situations where human safety is of utmost importance, as well as in settings where sensitive electronic equipment is present, as smoke and corrosive gases can damage electronic components. LSZH materials are also more environmentally friendly compared to traditional halogenated materials, as they release fewer harmful substances into the environment when burned.
Low Smoke Zero Halogen (LSZH) materials are used in a variety of applications where the release of smoke and harmful gases could pose a threat to human life or equipment. Here are some benefits of this material:
Less Toxicity: LSZH materials contain no halogens, which are known to emit toxic gases when burned. This makes them ideal for use in confined spaces such as aircraft cabins, submarines, and underground tunnels where the accumulation of toxic gases can pose a serious risk to human life.
Increased Safety: In addition to reducing toxicity, LSZH materials also reduce the amount of smoke produced during combustion. This helps to minimize the risk of smoke inhalation, which can cause serious health problems and impair visibility in emergency situations.
Improved Equipment Protection: LSZH materials are also beneficial for protecting equipment in the event of a fire. Since they produce less smoke, they can help to prevent smoke damage to sensitive electronic equipment, which can be costly to replace.
Environmental Friendliness: LSZH materials are also environmentally friendly, as they do not emit toxic gases when burned. This makes them a good choice for use in applications where sustainability and eco-friendliness are important considerations.
Compliance with Regulations: Many industries, including aerospace, transportation, and telecommunications, have regulations that require the use of LSZH materials in certain applications. Choosing LSZH materials can help ensure compliance with these regulations and avoid costly fines or other penalties.
