Abstract
The invention relates to a flexible silane crosslinked polyolefin elastomer insulating wire core and a manufacturing method thereof. The wire core comprises a conductor and an insulating layer, and is characterized in that: the insulating layer is made of a silane crosslinked polyolefin elastomer material in place of a silane crosslinked polyethylene material. The cable core provided by the invention has high bending resistance and the like, and is wide and safe in use. Withstand voltage tests of the insulating wire core show that the insulating wire core can withstand alternating current of 3.5kV for 5 minutes without breakdown. The bending resistance is not less than 18,000 times.
Description
Technical field
The present invention relates to a kind of flexible silane crosslinking polyolefin elastic body insulated wire cores and manufacture method.Belong to the cable technology field.
Background technology
Traditional silanes cross-linked polyethylene insulated cable is mainly used in the environment that fixedly lays, can not be applied to mobile occasion, mainly be because the silanes cross-linked polyethylene insulated cable body is harder, be not suitable for frequent moving, traditional moving all used rubber class flexible cable with cable, and power cable often uses ethylene propylene rubber insulated cable.Use ethylene propylene rubber insulatedly, make cable factory for many plastics classes and can not produce, therefore be subjected to very big placing restrictions on owing to there is vulcanization of rubber equipment.
How on the basis of existing plastic extruder, develop a kind of new silane crosslinking polyolefin elastic body insulated wire cores, can be applied to mobile occasion, replace traditional ethylene propylene rubber insulated power cable, thereby simplify production technology greatly and save manufacturing cost, this is the problem that those skilled in the art thirsts for solving.
Summary of the invention
The object of the present invention is to provide a kind of flexible silane crosslinking polyolefin elastic body insulated wire cores and manufacture method.
Because gentle elastic body insulated body core provided by the invention need frequently reverse in the use occasion of forming flexible cable, therefore must have good antitorque commentaries on classics performance and bending property.So the present invention at first sets about from material development, select silane crosslinking polyolefin elastic body insulating material for use, by this material is tested discovery, this material has following premium properties:
1, have good low-temperature resistance and resistance to wear, and fatigue durability, weather-resistant performance, anti-microbial performance, oil product, chemicals are had fabulous corrosion resistance.Common cable does not have resistance to wear and corrosion resistance.
2, bending resistance excellence: bending resistance is not less than 18,000 times.
3, have than ethylene-propylene rubber quite or better elasticity and flexibility.
In order to guarantee with the flexible silane crosslinking polyolefin material is that the core of insulating barrier has above advantage, and the present invention improves core from the following aspect:
1, conductor: conductor adopts the oxygen-free copper of high-quality, and the purity of copper reaches 99.95-99.99%.Conductor adopts zinc-plated or tin-coated copper conductor not according to the requirement of using, and conductor adopts and meets the requirement that IEC60228 stipulates the 5th kind or the 6th kind conductor regulation.Conductive surface should bright and clean, no greasy dirt, the burr of not damaged insulation, and the single line of projection or fracture.
2, insulating barrier: insulating barrier adopts the flexible silane crosslinking polyolefin elastic body material of the present invention's research and development, and the resistance to low temperature of insulation can reach-10 ℃, and thickness of insulating layer is selected for use and is fit to 1kV level and following voltage withstand class thickness, meets the regulation of GB/T12706.1-2008.
The present invention is first with the traditional ethylene-propylene rubber of silane crosslinking polyolefin elastic insulated material substitution, not only make the price of product more cheap, technology is simple and overcome the use limitation that the conventional silanes cross-linked polyethylene insulated cable lays, guarantee that product has good bending resistance, product has the advantages that to be extensive use of with safety.The technological process of making sees the description of embodiment for details.
The characteristic of the polyolefin elastomer insulated wire cores of crosslinked with silicane provided by the invention is:
1, cable voltage test: stand to exchange 3.5kV, continue 5 minutes, do not puncture.
2, bending resistance is not less than 18,000 times.
Description of drawings
Fig. 1 is an insulated wire cores structural representation provided by the invention;
Fig. 2 is the manufacture craft flow process of insulated wire cores;
Among the figure, 1 is flexible conductor, and 2 is insulating barrier.
Embodiment
Flexible silane crosslinking polyolefin insulated cable provided by the invention as shown in Figure 1, the technological process of wherein making described insulated wire cores as shown in Figure 2, wherein:
1, conductor:
Conductor adopts the 5th class or the 6th class conductor structure of GB/T3956 regulation, can zinc-plated or not zinc-plated two kind, and conductive surface is bright and clean, no burr, cut.
2, insulating barrier:
Insulating material adopts flexible silane crosslinking polyolefin elastic body material, and insulation thickness meets the requirement of GB/T12706.1-2008 regulation, guarantee insulated wire cores have good anti-ly reverse, high strength and electrical insulation properties.
From insulated wire cores manufacture craft flow process provided by the invention as can be known, it at first twists through the wire drawing posterior cord, the bunchy strand is after be twisted into conductor, lay insulating barrier then and form core, or directly lay insulating barrier after the bundle strand and constitute core, core provided by the invention is not less than its bending resistance 18,000 times because of the replacing of insulating layer material.
