Description
Technical field
The present invention relates to electric wire for automobiles, particularly relate to a kind of flame retardant automotive line CABLE MATERIALS.
Background technology
The cable used on automobile, weather conditions and working environment all compare badly, should bear the high temperature in summer, stand the cold in winter again, also have the humidity caused of raining.Existing automobile cable, owing to being difficult to bear so harsh working environment, often result in cable use long-time after, aging cracking or the softening of cable insulation occur, cause wire dew to cause car electrics short trouble；
Usual automobile electric wire polyvinyl chloride cable material production method is with Corvic for base material, add plasticizer, stabilizer and processing aid, process through special kneading device, although automotive line can be met produce primary demand, but there is the problem that abnormal smells from the patient is big, scraped finish performance is not good and processing characteristics is undesirable.Automotive line uses position special due to it, automobile cannot avoid the mutual friction between line and line in running, once the worn out meeting of plastic sheath directly results in short circuit and causes hidden peril of accident, in addition, automobile bodies is a space comparatively closed, the necessary environment-friendly tasteless of the kit item used in compartment, the healthy not damaged to people.In sum, automotive line PVC Insulation Material is except necessary electric property, it is necessary to scraped finish tasteless, resistance to.Through retrieving domestic patent, it has been found that existing patent is all not related to the innovative technology of this patent, now enumerate 3 Patents and illustrate.Mentioning in the patent of invention that the patent No. is 201,010,548,647 1 kinds of automotive line PVC of Suzhou Zhao Feng plastic cement company limited, from formula, automotive line PVC is solved Cost Problems, alternative Foreign Automobile line PVC still there is no performance and is obviously improved.The patent No. of Tianjin Dehao Ultrafine New Materials Co., Ltd is mention in CN201010599789.9 material special for flame-retarding polyvinyl chloride insulated cable, by the material special for flame-retarding polyvinyl chloride insulated cable that the design of formula and technique obtains, there is the electrical insulating property of excellence, processability and heat stability, good surface can be obtained with common screw extruder.And be applicable to automotive wire bundle manufacture, but improvement is sent to for abnormal smells from the patient and scraped finish.The patent No. of company limited of Sinopec is mention in 200810139982.7 1 kinds of automotive line electric wire igelites and preparation method thereof, adopts automotive line igelite prepared by Chemical Crosslinking Methods.Its wearability and thermostability improve, and in its formula, raw material types is more, and it contains the selection of cross-linking agent and initiator, there is the problem that raw material is chosen and quality consistency is relatively difficult to ensure card.
Summary of the invention
It is an object of the invention to provide a kind of flame retardant automotive line CABLE MATERIALS, it can effectively reduce abnormal smells from the patient, meanwhile, has excellent wearability, thermostability；Achieve again the surface and mechanical performance that have kept at high processing speeds.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of flame retardant automotive line CABLE MATERIALS, described flame retardant automotive line CABLE MATERIALS is processed by the component of following weight portion and is obtained: Corvic 100 parts, trioctyl trimellitate (TOTM) 25 parts, p-phthalic acid's dioctyl ester 11 parts, epoxy soybean oil 5 parts, calcium carbonate 19 parts, calcium-zinc composite stabilizing agent 7 parts, 1 part of high melting point polyethylene wax, phenolic antioxidant 1010 is 0.16 part, acrylic resin 2 parts, 3 parts of barium sulfate, silicone powder body 1.6 parts, Di-2-ethylhexyl terephthalate 1.5 parts, described high melting point polyethylene wax fusing point is higher than 105 DEG C.
The technical scheme improved further in technique scheme is as follows:
1, in such scheme, described PVC resin polymerization degree 1300.
2, in such scheme, described calcium carbonate is the one in calcene, nano-calcium carbonate.
3, in such scheme, described calcium carbonate is ground calcium carbonate.
4, in such scheme, the complex that described silicone powder body is siloxanes and silicon dioxide mixes according to the weight ratio of 1:4.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
1, flame retardant automotive line CABLE MATERIALS of the present invention, it selects the plasticizer that specific components and content trioctyl trimellitate (TOTM), p-phthalic acid's dioctyl ester, epoxy soybean oil form to arrange in pairs or groups with Corvic, the positive acting making these several plasticizers maximizes, namely the effect of every kind of plasticizer is played, wearability, abnormal smells from the patient or abnormal flavour is improved little while the mechanical property ensured or improve its excellence, High-speed machining performance, decreases the consumption of plasticizer simultaneously；Secondly, automotive line causes its phenomenon easily often rubbed against due to its restriction using environment, with the passage of time thin-walled automotive line will certainly conductor expose formation short circuit cause motor-vehicle accident, this product passes through formula adjustment, add containing 3 parts of barium sulfate, silicone powder body 1.5 parts, its wearability of centralized optimization, also enhances the corrosion resistance of product simultaneously；Again, polyvinyl chloride resin, plasticizer, processing aid and filler are in optimized selection and proportioning by this formula for a product especially, ensure its High-speed machining speed in automotive line production scene at 600 ~ 800m/min still to keep good surface up and down, line surface is without crude phenomenon；Again, the heat resistance of 105 DEG C of Insulation Material can be better strengthened by adding 105 DEG C of calcium-zinc composite stabilizing agents and antioxidant 1010 collocation.
2, flame retardant automotive line CABLE MATERIALS of the present invention, the Corvic adopting specific aggregation degree mates with specific plasticizer, significantly make Corvic that plasticizer absorption is relatively more abundant, so that the internal bond strength of material is comparatively tight, improve mechanical property further.
