Abstract
本实用新型涉及一种隔氧层阻燃耐火电缆包带,它由基材层(1)、隔氧层(2)和阻燃剂层(3)组成,其特征在于:基材层(1)的两面上分别涂有阻燃剂层(3),两个基材层(1)的阻燃剂层(3)间设有隔氧层(2)。当电缆着火时,隔氧层能释放出大量水份变成蒸汽,起到降温阻燃作用,当水份释放完后隔氧层高阻燃电缆包带烧结成一个筒状陶瓷体硬壳,隔断热氧反应,达到电缆难燃、耐火、自灭的作用,满足电缆在火场中继续通电的要求。
The utility model relates to a flame-retardant and fire-resistant cable tape with an oxygen barrier layer, which is composed of a base material layer (1), an oxygen barrier layer (2) and a flame retardant layer (3), and is characterized in that: the base material layer (1) ) are respectively coated with flame retardant layers (3), and an oxygen barrier layer (2) is arranged between the flame retardant layers (3) of the two base material layers (1). When the cable catches fire, the oxygen barrier layer can release a large amount of water into steam, which plays a role in cooling and flame retarding. After the water is released, the high flame retardant cable tape of the oxygen barrier layer is sintered into a cylindrical ceramic hard shell. Cut off the thermal oxygen reaction, achieve the functions of flame retardant, fire resistance and self-extinguishing of the cable, and meet the requirements for the cable to continue to be energized in the fire scene.
Description
本实用新型涉及一种隔氧层阻燃耐火电缆包带，具体的说是涉及一种基材层间设有隔氧层的电缆专用包带。The utility model relates to a flame-retardant and fire-resistant cable tape with an oxygen barrier layer, in particular to a special cable tape with an oxygen barrier layer between base material layers.
目前，随着我国国民经济的迅猛发展，我国电力工业也在日新月异地发生着变化，尤其是用于输电的电缆产量和质量也在成倍的增长。然而，由于电缆结构的不完善引发了不少火灾，也引起了广泛关注，在不断改进和完善阻燃耐火电缆的结构，目前，虽然有单层结构的阻燃包带在应用，但起不了隔氧层的作用，因为现有的阻燃包带本身具有阻燃和不燃的物质较少，当包裹在电缆芯线外的一层一旦电缆着火，不能在缆芯周围烧结成一个筒状硬壳隔氧层，阻断不了外部热氧反应的通道，达不到电缆阻燃的目的，所以现有的电缆包带不能满足电缆耐燃或阻燃的要求，故现有的电缆包带的结构有待于进一步改进。At present, with the rapid development of my country's national economy, my country's power industry is also changing rapidly, especially the output and quality of cables used for power transmission are also increasing exponentially. However, due to the imperfection of the cable structure, many fires have been caused, and it has also attracted widespread attention. The structure of flame-retardant and fire-resistant cables is constantly being improved and perfected. At present, although there are single-layer flame-retardant tapes in use, they cannot The role of the oxygen barrier layer, because the existing flame-retardant tape itself has less flame-retardant and non-combustible substances, when the layer wrapped outside the cable core wire once the cable catches fire, it cannot be sintered into a cylindrical hard core around the cable core. The oxygen barrier layer of the shell can't block the channel of external thermal oxygen reaction, and can't achieve the purpose of cable flame retardancy, so the existing cable tape can't meet the requirements of cable flame resistance or flame retardancy, so the structure of the existing cable tape To be further improved.
本实用新型的目的在于设计一种基材层间设有隔氧层的一种隔氧层阻燃耐火电缆包带，以克服现有技术的不足。The purpose of the utility model is to design a kind of flame-retardant and fire-resistant cable tape with an oxygen-barrier layer between the substrate layers to overcome the deficiencies in the prior art.
本实用新型的目的是这样实现的，它由基材层(1)、隔氧层(2)和阻燃剂层(3)组成，其特征在于：基材层(1)的两面上分别涂有阻燃剂层(3)，两个基材层(1)的阻燃剂层(3)间设有隔氧层(2)。The purpose of this utility model is achieved in that it is composed of base material layer (1), oxygen barrier layer (2) and flame retardant layer (3), and it is characterized in that: the two sides of base material layer (1) are respectively coated with There is a flame retardant layer (3), and an oxygen barrier layer (2) is arranged between the flame retardant layers (3) of the two base material layers (1).
本实用新型与现有技术相比：当电缆着火时，隔氧层能释放出大量水份变成蒸汽，起到降温阻燃作用，当水份释放完后隔氧层高阻燃电缆包带烧结成一个筒状陶瓷体硬壳，隔断热氧反应，达到电缆难燃、耐火、自灭的作用，满足电缆在火场中继续通电的要求。Compared with the prior art, the utility model is as follows: when the cable catches fire, the oxygen barrier layer can release a large amount of water to turn into steam, which plays the role of cooling and flame retardant. It is sintered into a cylindrical hard shell of ceramic body, which cuts off the thermal oxygen reaction, achieves the functions of flame retardant, fire resistance and self-extinguishing of the cable, and meets the requirements for the cable to continue to be energized in the fire scene.
