Description
Technical field
The invention belongs to a kind of cable material formula, specifically, particularly relate to a kind of 125 DEG C of irradiation cross-linking low smoke halogen-free fire retardant polyolefin cable materials.
Background technology
125 DEG C of irradiation cross-linking low smoke halogen-free fire retardant polyolefin cable materials are for meeting the characteristics such as low cigarette, Halogen be nontoxic, fire-retardant, high temperature resistant and a kind of retardant cable material developed.It is use polyolefine as base material, the inorganic anti-flaming material such as aluminium hydroxide, magnesium hydroxide makes fire retardant, through blended, plasticizing, granulation can cross-linking radiation CABLE MATERIALS.The exploitation of 125 DEG C of irradiation cross-linking low smoke halogen-free fire retardant polyolefin cable materials, solve following several key problem in technology: (1) is owing to can not use the fire retardant containing halogen, and the inorganic combustion inhibitor that aluminium hydroxide, magnesium hydroxide, zinc borate etc. are nontoxic can only be used, these fire retardants need interpolation 50% ~ 60% (weight percent) just to play good fire retardation, a large amount of interpolations of inorganic combustion inhibitor then significantly reduce the mechanical property of material, so how to ensure the balance of mechanical property and flame retardant properties, this is most important key problem in technology.(2) after adding a large amount of inorganic combustion inhibitors, the processing fluidity of material is very poor, and screw torque sharply rises, and granulation is produced very difficult, insulating exruded also very difficult, how to improve these Drawing abillities and be second key problem in technology.(3) if material melting drippage when burning, more easily make fire spread, the aggravation condition of a fire, also makes material expose the surperficial accelerate combustion made new advances.For this reason, anti-drippage just becomes another research of technique difficult point of this product of exploitation.(4) temperature resistant grade of material requirements is 125 DEG C, for making material can reach this class requirement, will solve the heat-proof aging problem of material well.
Summary of the invention
