Abstract
The invention relates to a novel low-smoke zero-halogen flame-retardant cable sheath material, which comprises the following components in percentage by weight: 15-35 percent of low-density polyethylene, 15-35 percent of ethylene-vinylacetate copolymer, 8-30 percent of modified nano magnesium hydroxide, 2-6 percent of microencapsulated red phosphorus, 8-19 percent of thermoplastic phenolic resin, 1.8-3 percent of dicumyl peroxide as a crosslinking agent, 0.1-0.25 percent of antioxidant 1010, 1-3.5 percent of lead sulfate tribasic as a lead compound and 0.1-1 percent of N-salicyl aminophthalimide as a copper inhibitor. According to the novel low-smoke zero-halogen flame-retardant cable sheath material, the consumption of the modified nano magnesium hydroxide is reduced by adding the thermoplastic phenolic resin and the microencapsulated red phosphorus on the basis of ensuring the performance of mechanical energy, and the purpose of synergically retarding flame is achieved. When the cable sheath material burns, the microencapsulated red phosphorus absorbs a great deal of water decomposed and released when the modified nano magnesium hydroxide burns, to generate phosphoric acid, metaphosphoric acid, polymetaphosphoric acid and the like which cover the surface of the thermoplastic phenolic resin with higher carbon content, so that the surface of the thermoplastic phenolic resin can be dehydrated and carbonized in an accelerating way to form a thick liquid film layer for isolating oxygen and heat from the inside sheath material, and thus burning can be weakened or interrupted, and the flame-retardant effect of the cable sheath material is enhanced; meanwhile, the novel low-smoke zero-halogen flame-retardant cable sheath material disclosed by the invention has the advantages of zero halogen, low smoke formation amount during burning and little pollution to environment.
Description
Technical field
The present invention relates to a kind of cable sheath material, especially novel low-smoke halogen-free inflaming-retarding cable sheath material.
Background technology
The existing material of making cable sheath is generally the polyolefins macromolecular material, and this is a kind of inflammable material, and after the surrounding environment presence of fire, flame can cause the expansion of flame along the cable rapid spread to whole circuit.In order to improve the flame retardant properties of cable, generally in cable jacket material, add halogenated flame retardant.But this type of sheath material amount of being fuming when burning that contains halogenated flame retardant is big, can produce macro-corrosion property gas and toxic gas, brings very big difficulty for fire extinguishing, escape, and causes secondary harm easily.
Summary of the invention
In order to overcome the deficiency of existing cable sheath material, the present invention provides a kind of novel low-smoke halogen-free inflaming-retarding cable sheath material, and flame retardant properties is good; The amount of being fuming is few; And do not contain halogenated flame retardant, even burning can not produce corrosive gases and toxic gas yet, be convenient to fire extinguishing and escape.
The present invention provides a kind of novel low-smoke halogen-free inflaming-retarding cable sheath material, and its component and content weight percentage are: new LDPE (film grade) 15～35%, ethylene-vinyl acetate copolymer 15～35%; Modified Nano Marinco H 8～30%, micro encapsulation red phosphorus 2～6%, novolac resin 8～19%; Linking agent Di Cumyl Peroxide 99 1.8～3%; Antioxidant 1010 0.1～0.25%, lead compound lead sulfate tribasic 1～3.5%, the amino adjacent benzene diimine 0.1～1% of anti copper agent N-bigcatkin willow.
Preparing method of the present invention adopts following process step:
Take by weighing material by prescription: new LDPE (film grade), ethene-vinyl acetate copolymer, modified Nano Marinco H, micro encapsulation red phosphorus, novolac resin, linking agent Di Cumyl Peroxide 99, antioxidant 1010, lead compound lead sulfate tribasic, the amino adjacent benzene diimine of anti copper agent N-bigcatkin willow; Place two roller open mills to carry out mixing these materials; 120～125 ℃ of the preceding roll temperatures of plasticator; 130～135 ℃ of back roll temperatures mixing about 20 minutes, are processed the present invention.
The invention has the beneficial effects as follows: on the performance basis that guarantees its mechanical energy,, reach the purpose of cooperative flame retardant through adding the consumption that novolac resin and microcapsule red phosphorus reduce the modified Nano Marinco H.Cable jacket material is when burning; Wherein micro encapsulation red phosphorus absorbs the modified Nano Marinco H burning time-division and separates the large quantity of moisture of release and generate phosphoric acid, metaphosphoric acid, gather metaphosphoric acid etc.; Be covered in the novolac resin surface that has than high carbon content, can make its surface quicken the dehydration carbonization, form very thick liquid film layer oxygen, heat and inner sheath material are separated; Can weaken or interrupt burning, strengthen the fire retardation of material.Simultaneously, material Halogen of the present invention, the burning fuming amount is few, and is little to the pollution of environment.
