The silane is grafted polyethylene resin which is added in a flame retardant polyethylene formulation so as to improve environmental stress crack resistance of flame retardant polyethylene cable materials, flame retardant dispersity and the surface of a cable sleeve extruded by flame retardant polyethylene, thereby solving the problems that flame retardant polyethylene cable sleeve is easy to crack and the mechanical property is poor.
Description
Technical field
The present invention relates to a kind of method with silane modified flame retardant polyethylene cable material.
Background technology
Now fire-retardant polyethylene cable material is used for electric wire, cable in a large number, extra-high-tension cable sheath especially, because the mechanical property and the processing characteristics of polyethylene excellence itself, fire-retardant polyethylene cable material is used widely in the production of power cable.
But because the characteristic of itself, having added has halogen fire retardant, and mechanical property descends to some extent because of the adding of fire retardant, if the fire retardant dispersiveness is bad, the easier fire-retardant polyethylene cable material mechanical property that causes descends and the data instability.Tensile strength and elongation at break do not reduce about 40% and 35% respectively before adding fire retardant.
Except mechanical property, the influence that its environmental stress cracking resistance is subjected to is particularly outstanding, because the extra-high-tension cable sheath need guarantee certain degree of hardness and mechanical property, must in prescription, add more high-density polyethylene resin, and the environmental stress cracking resistance of high-density polyethylene resin is relatively poor, particularly after having received a large amount of fire retardants, it is poorer that this performance shows.
Except weakening on the performance, processing characteristics is also poor slightly than general poly-ethylene cable material.Be filled with poly-ethylene cable material surperficial relatively poor of brominated flame retardant, until now, the difficult surface of accepting to have the halogen fire-retardant polyethylene cable material of cables manufacturing quotient representation of some amount arranged still on the market.
At present, there is halogen flame-proof polyethylene demand bigger, but has above three point problem.Therefore, how carrying out the modification work of fire-retardant polyethylene cable material, is this area problem demanding prompt solution.
