Due to adoption of halogen-free flame retardant, no environmental pollution is generated.
Description
Technical field
The utility model relates to the banded cable field, is specially a kind of halogen-free flameproof compound copper-plastics band.
Background technology
Compound copper-plastics band is the substitute products of cable with the fine copper band; It is one of important kind in the modern copper processing material; It has in light weight, intensity is big, high temperature resistant, shrink premium properties such as little; Face coat has favorable waterproof property, and the protection cable core gas cut that do not make moist is attacked, and the application on telecommunication cable, Communication ray cable industry continues to increase.Compound copper-plastics band is that fine copper belt and plastic layer heat posted form, and the shared thickness ratio of plastic layer has met or exceeded half the, because plastics are easy to burning, compound copper-plastics band are used have certain potential safety hazard.Therefore need carry out flame-retardant modified to the compound copper-plastics band plastic layer.The mode that flame retardant of plastic generally uses halogen-antimony to combine, but because of halogen to serious environment pollution, fire-retardant for plastic is non-halogen to be current development trend.
The utility model content
The purpose of the utility model is to provide a kind of superthin structure halogen-free flameproof compound copper-plastics band that has, and solves the combustible potential safety hazard that compound copper-plastics band exists on the one hand, avoids halogen containing flame-retardant that environment is polluted on the other hand.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of halogen-free flameproof compound copper-plastics band, compound copper-plastics band are coated on telecommunication cable or optical cable outer surface, and compound copper-plastics band comprises red copper layer and halogen-free antiflaming polyester thin layer successively.
Said compound copper-plastics band is followed successively by red copper layer, adhesive layer and halogen-free antiflaming polyester thin layer.Said adhesive layer 2 thickness are 0.0015～0.015mm.The compound copper-plastics band gross thickness is 0.028～0.308mm.Said red copper layer 1 thickness is 0.02～0.2mm, and halogen-free antiflaming polyester thin layer 3 thickness are 0.008～0.058mm.
The advantage and the beneficial effect of the utility model are:
1, a kind of compound copper-plastics band with fire resistance is provided, has improved its safety in utilization, enlarged the product range of application.Adopted halogen-free flame retardants, environment has not been polluted.
2, the utility model compound copper-plastics band has superthin structure, has saved the copper material of a large amount of preciousnesses, has reduced production cost.
3, the utility model compound copper-plastics band employing halogen-free flameproof biaxially oriented polyester film and copper strips are compound; With reference to GB/T16958-2008; Polyester film hot strength >=150MPa; Substantially exceed the intensity of general ethylene copolymer or vinyon layer, guaranteed the bulk strength of compound copper-plastics band behind the copper strips attenuate.Because biaxially oriented polyester film has good resistance to wear, folding resistance and tear resistance etc., can improve the application property of product.Through flame-retardant modified rear film stable performance, good flame retardation effect.The Zero halogen flame resistance polyethylene film has been preserved polyethylene film excellent chemical stability, heat sealability, resistance to water and moisture resistance, and deep freeze resistance etc. have increased anti-flammability.
4, developed the novel halogen-free flame-retardant adhesive that is applied to compound copper-plastics band, it has good flame retardancy, and electrical property reaches stronger bonding force etc. around Qu Xingneng.
