Description
Technical field
The present invention relates to CABLE MATERIALS technical field, be specifically related to a kind of to there is organosilane cross-linked poly-ethylene cable material of sound absorption sound insulation function and preparation method thereof.
Background technology
Along with the development of modern science and technology, the specification of quality of people to electric wire is more and more higher, and the appearance of organosilane crosslinked polyethylene compensate for the deficiency of common polythene electric wire.Organosilane cross-linked poly-ethylene cable material can improve transmission capacity, the overload capacity of circuit, and this material is when manufacturing cross-linked wire and cable, compare with cross-linking radiation with peroxide crosslinking, there is required producing apparatus simple, easy to operate, the advantages such as comprehensive cost is low, the insulating material as lv power cable has become the leading material of low-voltage crosslinked cable insulation at present in China's wires and cables industry.
High density polyethylene(HDPE) is cheap, light weight, excellent property, but the linear molecular structure of high density polyethylene(HDPE) determines it exists performance deficiency at relatively high temperatures, as inter-molecular binding force declines, easily deformation occurs, shows as creep increase, rigidity and mechanical properties decrease; High density polyethylene(HDPE) is non-polar polymer, though have good barrier to water polar solvent, the organic solvents such as p-Xylol have higher perviousness, and barrier properties for gases is also bad.Nylon is polar polymer, to the good barrier property of non-polar solvent, gas, but poor to the barrier of polar solvent, and nylon easily absorbs water, thus reduce the mechanical property of material.The high density polyethylene(HDPE) of crosslinked with silicane modification and nylon are carried out blended, although the barrier of CABLE MATERIALS can be improved, but function is comparatively single, also existing defects in wear resistance, bending resistance, ageing-resistant degree, perishable situation, intensity and resistance to property at sunshine etc.
