Description
Technical field
The invention belongs to polymeric material field, it is related to a kind of low smoke halogen-free flame-retardant polyolefin plastics, specially a kind of light
Effective thermoplastic low-smoke halide-free fireproof composite polyolefine PP Pipe Compound of cable microbeam and preparation method thereof.
Background technology
With " broadband China " implementation, " integration of three networks " and FTTH, which are built, in depth to be carried out, and 4G communications are built
If bringing more novel optical fiber application demands, the various Novel wiring optical cables for meeting house wiring demand arise at the historic moment, microbeam pipe
Wiring optical cable is successfully applied to several scenes, with good combination property.A series of rooms can be derived by microbeam pipe unit
Interior wiring optical cable, the serial optical cable has that size is small, lightweight, core number big, excellent fireproof performance the features such as, while having good
Good environment and mechanical performance.Low smoke halogen-free flame-retardant polyolefin material is the optimal material for preparing microbeam pipe, its good combination property, just
Gradually substitute the effective material of other microbeams.
Early in 2000, it is special that Jiangdu City, Jiangsu Province Ju Bao Special Resins cable factory succeeds in developing optical fiber microbeam Loose tube PBT
Materials, and put into production.Patent of invention CN1262290A, material dedicated for elastic sleeve tube of optical cable and optical fibres and CN102675608A, PBT optical fiber
The preparation method of material dedicated for elastic sleeve tube individually discloses a kind of synthesis preparation method of PBT microbeams material dedicated for elastic sleeve tube, Neng Gouman
Sufficient Loose tube prepares at a high speed production.Optical fiber is traditional material with PBT microbeam Loose tubes, and mechanical and physical performance and processing characteristics are excellent
It is different, but it is not fire-retardant, and can be produced thick smoke during burning.Other PBT material are as engineering plastics, and difficulty of processing is relatively large, works as plasticizing
When insufficient, Loose tube easily occur enclosed mass, goes out the problems such as die orifice just ruptures.
A kind of patent of invention CN103205057A, modified polypropene Loose tube proprietary material discloses a kind of modified polypropene
The formula composition of microbeam Loose tube proprietary material, patent of invention CN104072930A, a kind of optical cable loose tube polymer alloy
Material and its preparation method and application discloses a kind of optical cable loose tube polymer alloy material and preparation method thereof, and Jiangsu is prosperous
Logical Photoelectric Co., Ltd. also have developed a kind of Full-dry optical cable double-layer coextrusion Loose tube, Loose tube ectonexine material therefor
For PP and PP and PP (or PE) color masterbatch.Such polyolefine material has processing characteristics excellent, and expression surface is smooth, extruded velocity
It hurry up, high hardness high toughness, hydrolysis, the Loose tube of extrusion is not easily broken, but it is not fire-retardant.
Utility model patent CN203191599U discloses a kind of structure composition of ultra-thin glass fiber microbeam Loose tube, therein
Although Loose tube is to be extruded to form with halogen-free fire-retardant polyethylene material, but the effective low smoke halogen-free flame-retardant polyolefin material of common microbeam is squeezed
Go out speed slow, dimensional stability is not good, easily shrinks yielding, beam tube inwall is rough and causes to draw and wears that optical fiber is difficult or optical fiber mistake
Degree bending etc.；Such material bending modulus and modulus of elasticity are relatively low, and optical cable easily rolls over flat when bending, and influence fiber-optic signal；In system
When making wet type optical cable, due to needing factice for filling in microbeam pipe, outside will fill cable cream, and common polyolefin jacket material is easily produced
Raw swelling set or rupture；Oversheath is extruded outside microbeam pipe or when optical cable is under alternating temperature-changing environment, common protective cover material
Easily sticked together with adjacent optical fiber, restrictive coating, waterstop, stiffener assembly etc. and cause the reduction of optical cable transmission ability；Commonly
The fire resistance of low-smoke halogen-free flame retardant material is generally not enough, easily drips and diffusion flame, is unfavorable for suppressing propagation of flame；Other are micro-
Beam tube material, although such as polyvinyl chloride fire resistance is good, its poor toughness can discharge toxic gas during burning.
The content of the invention
The technical problem of solution：In order to overcome the defect of prior art, the existing polyolefine material of solution is not fire-retardant, burning is released
The problem of being placed with poisonous gas, poor toughness, not good stability, obtains a kind of suitable for small micro-dimension, individual layer multilayer, single multicore etc.
