Description

Flame-retardant, silane-crosslinked poly-ethylene cable material of a kind of low smell and preparation method thereof
Technical field
The present invention relates to CABLE MATERIALS technical field, be specifically related to flame-retardant, silane-crosslinked poly-ethylene cable material of a kind of low smell 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.
Summary of the invention
Object of the present invention is just to provide flame-retardant, silane-crosslinked poly-ethylene cable material of a kind of low smell and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
The flame-retardant, silane-crosslinked poly-ethylene cable material of a kind of low smell, it is characterized in that, be made up of the raw material of following weight part: high density polyethylene(HDPE) 58-68, metallocene PE 22-32, nylon 6 13-16, antioxidant 330 0.2-0.3, glyceryl monostearate 4-6, vinyl methyl dimethoxysilane 13-17, magnesium hydroxide 6-9, urea 3-5, silicon nitride fiber 8-10, wollastonite 16-20, aqueous acroleic acid resin 35-45, water are appropriate.
The preparation method of the described flame-retardant, silane-crosslinked poly-ethylene cable material of a kind of low smell, is characterized in that comprising the following steps:
(1) wollastonite is calcined 2-3 hour in 640-780 DEG C, cooling adds magnesium hydroxide grinding 30-40 minute, obtained modified wollastonite powder;
(2) nylon 6 is dropped into high mixer after 80 DEG C of dry 24h in vacuum drying oven together with modified wollastonite powder, antioxidant 330, glyceryl monostearate to stir, join mixing granulator in forcing machine;
(3) silicon nitride fiber is dropped in aqueous acroleic acid resin soak 5-8 hour, dry and pulverized 100-200 mesh sieve, add vinyl methyl dimethoxysilane dispersion grinding 30-50 minute, obtain silane recombiner;
(4) high density polyethylene(HDPE), metallocene PE are dropped into high mixer, add silane recombiner, stir, add step (2) material and other remaining component mixing and stirring, putting into single screw extrusion machine extrudes in flakes, test piece is put into the crosslinked 6-8 hour of 80 DEG C of water-baths, discharging.
The present invention has following beneficial effect: the present invention adds anti-tear the drawing property that silicon nitride fiber improves CABLE MATERIALS, the reticulated structure that polyethylene composite carries out the modified formation of crosslinked with silicane can effectively stop oily substance to the intramolecular diffusion of intermingling material, carry out blended with the nylon 6 of modification again, also add that the obtained CABLE MATERIALS of other effective auxiliary agents has that barrier property is excellent simultaneously, low pollution-free, the advantage such as cost is low, flame retardant resistance is strong of smell.
