Description
Technical field
The present invention relates to optical fiber jacket material technical field, optical fiber jacket material particularly relating to a kind of long service life and preparation method thereof.
Background technology
Along with the develop rapidly of data communication industry, optical fiber is just widely adopted as the carrier of data transmission.The laying form of optical fiber is buried and built on stilts, and along with the transformation of city netting twine, major part goes underground.In order to prevent the optical fiber of underground, optical cable suffers insect bite or corrosion, and the sheath material of optical fiber and optical cable arises at the historic moment.Current optical fiber, protecting sleeve of optical cable mainly use polyolefine, have light weight, flexural strength is large, frictional coefficient is little, good seal performance, the feature such as corrosion-resistant, but this tubing also exists extremely incendive shortcoming.Initial in order to improve the flame retardant properties of sheath protecting materials; general interpolation contains the fire retardant of halogen; these type of fiber optic cables can release a large amount of smog and hydrogen halide in combustion; people is made to be choked to death in fire; simultaneously comparatively large to plant and instrument corrodibility, therefore the development and application of low cigarette, low halogen and bittern-free flame-proof material has been one of developing direction of domestic and international fiber optic cables and other field.
Inorganic no-halogen fire retardant has stronger polarity and wetting ability, and polyolefine is non-polar material, poor compatibility between the two, interface is difficult to form good combination and bonding, particularly magnesium hydroxide magnesium hydroxide has excellent fire-retardant, press down cigarette, resistance is dripped, antiacid several functions such as grade, be widely used, but magnesium hydroxide polarity is strong, different from resin thermal expansivity, expand with heat and contract with cold during machine-shaping and cause two-phase interface to form microcrack, this will cause the mechanical property of material, water resistance, the decline of insulating property, so surface modification must be carried out to magnesium hydroxide, make magnesium hydroxide in polyolefine, have good over-all properties, have at processing temperatures in good mobility and use temperature and have high intensity and toughness concurrently, and do not change the shock resistance of polyolefine section bar.
Summary of the invention
