Description
Technical field
The present invention relates to a kind of communication material, particularly relating to a kind of plastic sheeting for making optical cable or cable shield and preparation method thereof, belonging to communication Material Field.
Background technology
The structure collectivity of optical cable can be divided into cable core, screen layer (that is, metal plastic composite strip layer), restrictive coating three parts.Wherein, cable core is the effect of signal transmission; What screen layer adopted is metal plastic composite strip material, is closely wrapped up by cable core by metal plastic composite strip vertical bag, airtight.Shielding, armouring, anticorrosion, moistureproof effect; It is a kind of vinyon material that restrictive coating adopts; after certain temperature is melted; by the mode extruded together with the plastics tight bond on metal plastic composite strip surface, not easily peel away, play the protective effect of anticorrosion, protection against the tide, anti-external world.
The application of metal plastic composite strip in the communication materials such as fiber optic cable widely.The main material of metal plastic composite strip is made up of metal level and plastic film layers.And the plastic film layers that current metal plastic composite strip uses mostly adopts be ethene---acrylic copolymer resin, ethene---methacrylic acid copolymer resin, ethylene-vinylacetate copolymer, low density polyethylene (LDPE) and LLDPE resin, by certain weight proportion through three-layer co-extruded technique blowing.Flow out in circular die mouth like in monofilm after this melt of three layers is laminated in die cavity, due to the thermoplasticity of this several plastic raw materials and melting fabulous, so after they flow out die cavity when extruding, what bond between layers is just quite firm, and plastic sheeting just cannot be made to form the effect of layering.
And communications optical cable cable needs connecting and torsional buckling of manpower or pulling equipment when constructing erection, in order to avoid pulling during construction erection, the situation damaging optical fiber such as to sprain, do not affect the transmission of optical fiber or the quality of Received signal strength, after the fiber optic cable made, need to do torsional buckling experiment, that is: together with cable core can closely be wrapped up with metal plastic composite strip, and external sheath layer is divided into two parts from the disengaging of metal plastic composite strip completely.Its experimentation is: be fixed on the fixed support of torsional buckling experimental machine by one end of fiber optic cable long for the 500mm got, after the other end removes the long external sheath layer of 50mm, be fixed on the support of experimental machine left rotation and right rotation, unlatching experimental machine is carried out left and right and is repeatedly rotated torsional buckling more than 300 times, the entirety of external sheath layer and cable core and screen layer departs from completely, and the entirety of cable core and screen layer is not destroyed.In addition, communications optical cable cable, when constructing erection, needs to carry out length connection.And use the metal plastic composite strip that existing this plastic sheeting makes, when constructing erection due to bonding quite firm between external sheath layer and metal plastic composite strip, be difficult to restrictive coating from peel-away removal metal plastic composite strip, have impact on the progress of fiber optic cable when constructing erection completely, meanwhile, also cause the materials such as the cable core of fiber optic cable not to be reused and cause waste.
Summary of the invention
The present invention is directed to during existing metal plastic composite strip plastic sheeting uses the deficiency existed, provide a kind of can the plastic sheeting and preparation method thereof of control hierarchy.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of can the plastic sheeting of control hierarchy, comprise adhered layer, easily tear layer and peel ply, it is characterized in that, described adhered layer is made up of ethylene-acrylic acid copolymer or ethylene-methacrylic acid copolymer, described easily tear layer by vinyl acetate content lower than 20% ethylene-vinyl acetate copolymer, ethylene-methyl methacrylate ionomer, poly 1-butene, silica, β-propionic acid octadecyl, three phenyl-phosphites, N, N '-ethylene bis stearamide, 2, 6-di-tert-butyl-4-methy phenol, oleamide, triphenyl phosphate, the blend that oleyl palimitamide is mixed to form according to a certain weight ratio is made, described peel ply is by ethylene-vinyl acetate copolymer, low density polyethylene (LDPE), the blend that linear low density polyethylene resin material is mixed to form according to a certain weight ratio is made.
The invention has the beneficial effects as follows: structure of the present invention can control hierarchy plastic sheeting make fiber optic cable screen layer composite band after, adhered layer can compound paste on the surface of the metal level of metal plastic composite strip securely, and the external sheath layer of fiber optic cable also can with can control hierarchy plastic sheeting peel ply tight bond together with, by easily tearing layer and its not molten effect repelled mutually, the external sheath layer of fiber optic cable can be easy to be separated from adhered layer, and do not destroy adhered layer, ensure that metal plastic composite strip not by the intrusion of moisture, there is good moisture-proof role, when screen layer is not damaged, thus protect cable core.In addition, the recycle value of cable core can be improved and the progress of fiber optic cable at erection construction can be improved.
Principle of the present invention is as follows:
Adhered layer requires with the adhesion strength of the metal level of metal plastic composite strip higher, the fusing point of---acrylic copolymer (EAA) or ethene---methacrylic copolymer resins (EMAA) lower (fusing point: 70 DEG C ~ 90 DEG C) because the ethene that adhered layer uses, thermoplasticity is good, fusing time is short, is easy to bond with the metal level of metal plastic composite strip firm.Peel ply requires the external sheath layer tight bond with fiber optic cable, because the fusing point of the ethylene-vinylacetate copolymer that peel ply uses and low density polyethylene (LDPE) and LLDPE is lower (fusing point: 90 DEG C ~ 120 DEG C) also, the fusing point of the external sheath layer of fiber optic cable is at 100 DEG C ~ 120 DEG C, fusing point is close, and the jacket material of these plastic raw materials and fiber optic cable has great similitude and affinity in chemical composition, be easy to be fused together, therefore, bonding is also very firm.Easily tear ethylene-vinylacetate copolymer (EVA), ethene that layer uses---methacrylate ion polymer (suryn), poly 1-butene (PB-1), β-propionic acid octadecyl, oleyl palimitamide, 2,6-di-tert-butyl-4-methy phenol, silica, triphenyl phosphate, three phenyl-phosphites, N, N '-ethylene bis stearamide (EBS wax) material, chemically poor with the melting of adhered layer and peel ply material therefor on composition, there is the effect repelled mutually, that is: serve the effect of obstruct.When the melt of this trilamellar membrane is extruded simultaneously, flow out in circular die mouth like laminated after image monofilm in die cavity, the particularity of material is adopted owing to easily tearing layer, cause the bonding strength between adhered layer and peel ply lower, namely cannot be bonded together very securely, thus peel ply and adhered layer can be cut separation, and mutually do not destroy.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the described weight proportion easily tearing each component in layer is as follows: vinyl acetate content lower than 20% ethylene-vinyl acetate copolymer: 35 ~ 38%, ethylene-methyl methacrylate ionomer: 45 ~ 48%, poly 1-butene: 18 ~ 20%, silica: 0.4 ~ 0.5%, β-propionic acid octadecyl: 0.1 ~ 0.2%, three phenyl-phosphites: 0.1 ~ 0.2%, N, N '-ethylene bis stearamide: 0.1 ~ 0.2%, 2, 6-di-tert-butyl-4-methy phenol: 0.1 ~ 0.2%, oleamide: 0.1 ~ 0.2%, triphenyl phosphate: 0.2 ~ 0.3%, oleyl palimitamide: 0.1 ~ 0.2%.
