Description
Technical field
The present invention relates to the sheath level soft pvc plastics that a kind of cable is used, particularly electric wire PVC environment friendly transparent sheath material.
Background technology
In the insulation and sheath material of electric wire, the PVC(polyvinyl chloride) more cheap, mechanical property is good, and is easy to process, makes it become for a long time the maximum material of wires and cables industry usage quantity.Since 20 end of the centurys, the environmental problem of PVC material extensively is familiar with, and some developed countries have proposed restriction or completely forbidden the decree suggestion of using the PVC cable.In recent years, control and ban use of the PVC material to form strong trend.
Although replace the cry of PVC material with the Halogen material more and more higher, but PVC itself has the advantage that also can't replace in a short time, as cheap, good flame resistance, processing units, technique are simple, and the hardness variable range is wide, and electrical insulating property is good, so oil resistant, chemical-resistant reagent etc. are the use of short-term internal world scope total ban PVC and unrealistic.
In China, PVC CABLE MATERIALS development early, kind, model are more.In the recent period, due to the raising that Environmental Protection in China requires, the development of China PVC CABLE MATERIALS is also on a declining curve gradually.Because the PVC CABLE MATERIALS is cheap, the multiple advantage such as mechanical property excellence, make China PVC CABLE MATERIALS still have in the recent period certain development prospect in addition.But domesticly should pay attention to studying non-leaded PVC or the not halogen-containing environment-friendly type electric wire of development of new.Although the environment-friendly type electric wire replaces the PVC cable also to want considerable time at home on a large scale, this is trend of the times, and therefore the environment-friendly cable material of research and development use PVC is a large technical barrier
Fast development along with society, video equipment is universal rapidly, the use of video electrical wire is more and more extensive, and video electrical wire requires to have shielding properties preferably, the screen layer outside of video capable electric wire all needs to have sheath to coat, allow arranging situation wiry in metal screen layer, arrange the quality condition such as tightness degree, can't be from known outside, if therefore can develop transparent sheath material, can address this problem well.
Summary of the invention
The object of the present invention is to provide a kind of electric wire that can satisfy simultaneously the performance requriements of H-70 type in the transparent requirement of oversheath of video electrical wire, the environmental requirement of satisfying the ROHS of European Union standard and " soft PVC plastic for electric wire and cable " standard GB/T 8815-2008 PVC environment friendly transparent sheath material.
Realize that the object of the invention technical scheme is: a kind of electric wire PVC environment friendly transparent sheath material, its composition and proportioning are counted with mass parts:
Above-mentioned electric wire PVC environment friendly transparent sheath material, described softening agent is the mixture of dioctyl terephthalate, dioctyl phthalate (DOP) and epoxy soybean oil, in the total component of formula, dioctyl terephthalate is 28～35 mass parts, dioctyl phthalate (DOP) is 5～15 mass parts, and epoxy soybean oil is 2～10 mass parts.
Above-mentioned electric wire PVC environment friendly transparent sheath material, described oxidation inhibitor is dihydroxyphenyl propane.
Above-mentioned electric wire PVC environment friendly transparent sheath material, described transparent type calcium-zinc composite stabilizing agent is YC-197.
Above-mentioned electric wire PVC environment friendly transparent sheath material, described lubricant is polymer complex ester brightening agent GH-104.
Above-mentioned electric wire PVC environment friendly transparent sheath material, the described yellow agent that disappears is the ultramarine powder.
Above-mentioned electric wire is to select the vinyl chloride monomer of ethylene process preparation and the polyvinyl chloride resin powder of suspension polymerization preparation with PVC environment friendly transparent sheath material, described polyvinyl chloride resin.
after having adopted technique scheme, the present invention has following beneficial effect: (1) PVC itself is transparent, but itself can not use the polyvinyl chloride resin powder separately, must add multiple auxiliary agent, could be used for goods after processing, yet Pb stabilizer commonly used, opaque, poisonous, not environmental protection, therefore the present invention selects the transparent type calcium-zinc composite stabilizing agent, has the transparency good, nontoxicity, tool is from slip, can use separately, long-term thermal stability is good, anti-sulphur and weathering resistance are good, with PVC and plasticizer compatbility is excellent and the advantage that meets the ROSH standard, therefore transparent sheath material of the present invention can satisfy the transparent sheath service requirements of video electrical wire, still can directly inspect the quality conditions such as arranging situation wiry in metal screen layer, arrangement tightness degree after finished product, guarantee the quality of video electrical wire, and its environmental-protecting performance can satisfy the ROHS of European Union standard-required, and its traditional performance satisfies the index request of H-70 type in standard " soft PVC plastic for electric wire and cable " GB/T 8815-2008.
(2) for the PVC formula of not environmental protection, stablizer selection nargin is large; PVC formula for environmental protection, stablizer selection nargin is little, therefore require to coordinate the plasticiser system variation to strengthen " heat-stable time ", increase the transparency, the present invention selects three kinds of softening agent to consist of Plasticising system, these three kinds of softening agent may be used in transparent PVC, but the dioctyl terephthalate resistance toheat is better than o-phthalic acid dibutyl ester, but the plasticizing efficiency of o-phthalic acid dibutyl ester is higher than dioctyl terephthalate, so mix a small amount of o-phthalic acid dibutyl ester, strengthen plasticization effect; Epoxy soybean oil is a kind of extender plasticizer, but resistance toheat is better than o-phthalic acid dibutyl ester, and plasticization effect is worse than o-phthalic acid dibutyl ester, uses epoxy soybean oil, is also mainly to need to strengthen " heat-stable time "; So the extraordinary reinforcement heat-stable time of Plasticising system energy that these three kinds of softening agent consist of, the transparency of increase sheath material.
(3) stabilising effect due to the environmental protection stablizer does not have the good of plumbous class, but Pb stabilizer is poisonous, not environmental protection, and the dihydroxyphenyl propane that the present invention selects is oxidation inhibitor, after dihydroxyphenyl propane and environmental protection stablizer are also used, effectively improved " heat-stable time ", prevented PVC " xanthochromia ", stablized the transparency.
(4) the lubricant polymer complex ester brightening agent GH-104 of the present invention's selection is that a kind of green CABLE MATERIALS with heat stabilization is lubricated and brightening agent, and it can reduce plasticization temperature, improves extruded velocity, make the lubricated light of polyvinyl chloride cable material, bright in colour.Have that mobility is fast, the characteristics of good dispersity, not backfin, no blooming, its outward appearance be extremely little yellow flap, 44 ~ 54 ℃ of molten points, flash-point more than 245 ℃ of white.
(5) the present invention selects whitening agent to increase transparency; Select the ultramarine powder Huang that disappears; Finally make finished product have good transparency and the feature of environmental protection.
