Abstract
The utility model relates to the field of cable belts, in particular to a copper plastic composite belt applicable to telecommunication cables and optical cables. The copper plastic composite belt is wrapped on the outer surfaces of the telecommunication cables or the optical cables, and the copper plastic composite belt is sequentially provided with a red copper layer, an adhesive layer and a polyester film layer. The copper plastic composite belt has an ultrathin structure, saves a great number of valuable copper products, and reduces production cost. The product can replace pure copper cable mask belts for a certain degree.
Description
Technical field
The utility model relates to the banded cable field, is specially a kind of compound copper-plastics band that is applicable to communication cable and optical cable.
Background technology
Compound copper-plastics band is the substitute products of cable with the fine copper band, is one of important kind in the modern copper processing material, and the application on communication cable, Communication ray cable industry continues to increase.At present, the production standard of compound copper-plastics band is a base material with the fine copper band promptly generally with reference to YD/T 723.4-2007; Thickness is more than 0.1mm; Plastic foil adopts ethylene copolymer or sealed polyethylene plastic, thickness more than 0.05mm, the tensile strength >=15MPa of plastic foil.With the further attenuate of fine copper tape base material, and then the compound copper-plastics band gross thickness is reduced, can further reach and practice thrift copper resource, the purpose that reduces cost.Yet intensity descends behind the copper strips attenuate, adopts ethylene copolymer or sealed polyethylene plastic to be difficult to satisfy the bulk strength requirement of compound copper-plastics band.In addition, in practical operation,, require plastic layer to have wearability, folding resistance and anti tear type etc. because factors such as bending, scratch plastic layer often take place damage phenomenon.Therefore polyethylene and ethylene copolymer can not satisfy actual needs fully.And biaxially oriented polyester film has intensity height, good rigidly, outstanding obdurability, and its tensile strength is 10 times of low density polyethylene (LDPE); Characteristics such as excellent abrasion resistance, folding resistance, anti-pin hole property and tear resistance are arranged; Simultaneously; Its also possess do not have smell, tasteless, colourless, nontoxic, heat-shrinkable is minimum, has good antistatic behaviour, insulating properties; Good hear resistance, low temperature resistant freezing property; Good oil resistivity and chemical-resistant, it belongs to polar macromolecule material and combines closely etc. with adhesive, can satisfy ultra-thin compound copper-plastics band requirement.
The utility model content
The purpose of the utility model is to provide a kind of compound copper-plastics band that is applicable to communication cable and optical cable.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of compound copper-plastics band, compound copper-plastics band are coated on communication cable or optical cable outer surface, and compound copper-plastics band is provided with red copper layer, adhesive layer and laminated polyester film successively.
Said compound copper-plastics band gross thickness is 0.0295～0.64mm.Said red copper layer thickness is 0.02～0.2mm, and the polyester film layer thickness is 0.008～0.036mm, and adhesive layer thickness is 0.0015～0.08mm.
The advantage and the beneficial effect of the utility model are:
1, 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.Make product instead of pure copper cable mask tape to a certain extent.
2, the utility model compound copper-plastics band employing biaxially oriented polyester film and copper strips are compound; With reference to GB/T16958-2008; Polyester film hot strength >=150MPa substantially exceeds the intensity of general ethylene copolymer or vinyon layer, has guaranteed the bulk strength of compound copper-plastics band behind the copper strips attenuate.Because biaxially oriented polyester film has good wearability, folding resistance and tear resistance etc., can improve the application property of product.
3, the utility model compound copper-plastics band has improved the adhesive prescription; At the ripe fabulous electrical property that has; Around Qu Xingneng, increase the peel strength that the ethylene-methyl methacrylate methyl terpolymer component with preferred metal cementability has further improved compound copper-plastics band after need not in the polyesters glue of cured.
Description of drawings
Fig. 1 for the utility model embodiment provide the compound copper-plastics band structural representation; Wherein, 1. red copper layer, 2. adhesive layer, 3. laminated polyester film.
The specific embodiment
Be described further below in conjunction with the structure of accompanying drawing the utility model.
As shown in Figure 1, compound copper-plastics band of the present invention is the composite construction of red copper layer 1 and biaxially oriented laminated polyester film 3, and red copper layer 1 is composited by adhesive layer 2 bonding heating with laminated polyester film 3.
Among the present invention, red copper layer 1 is for to obtain through cold rolling, and the gross thickness of compound copper-plastics band is 0.0295～0.64mm; Wherein, The thickness of red copper layer 1 is 0.02～0.2mm, and the thickness of biaxially oriented laminated polyester film 3 is 0.008～0.036mm, and adhesive layer 2 THICKNESS CONTROL are 0.0015～0.08mm.Said biaxially oriented polyester film (inspiring confidence in many Industrial Co., Ltd.s available from Shanghai) adopts the PET biaxially oriented polyester film; Adopt such plastic layer; Its benefit is: with reference to GB/T16958-2008; Polyester film hot strength >=150MPa substantially exceeds the intensity of general ethylene copolymer or vinyon layer, has guaranteed the bulk strength of compound copper-plastics band behind the copper strips attenuate.Because biaxially oriented polyester film has good wearability, folding resistance and tear resistance etc., can improve the application property of product.
Adhesive: its main component and mass fraction are ethylene-methyl methacrylate methyl terpolymer 20%, saturated polyester 32%, and epoxy resin 32%, melamine resin 6%, polyurethane 10%, and add the p-methyl benzenesulfonic acid that accounts for resin gross mass 0.6%.Have fabulous electrical property, around Qu Xingneng, need not the back cured, characteristics such as preferred metal cementability have further improved the peel strength of compound copper-plastics band.
Said adhesive layer is that resin and p-methyl benzenesulfonic acid are formed; Said resin is by mass fraction, ethylene-methyl methacrylate methyl terpolymer 18-22%, saturated polyester 29-35%; Epoxy resin 29-35%; Melamine resin 4-8%, polyurethane 8-12%, the addition of p-methyl benzenesulfonic acid is resin gross mass 0.5-0.7%.The addition of methyl methacrylate is the 15-30% of copolymer gross weight in the said ethylene-methyl methacrylate methyl terpolymer.Said saturated polyester is Vylon560,335,345,301B, 385 saturated polyesters, and wherein saturated polyester 335,345,301B, 385 are available from Hualun Chemical Co., Ltd., Jiangsu; Vylon560 is available from spinning (TOYOBO) in Japanese Japan; Epoxy resin 6101,634 is available from Shenyang City's applied chemistry research institute; Melamine resin is available from green source, Jiashan chemical industry Co., Ltd melamine; Polyurethane polyurethane tpu is available from Bayer A.G (Bayer).
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit of the present invention and the principle, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
