Description

耐火1100℃矿物质低压电缆及其制备方法
技术领域
本发明涉及一种电缆，尤其涉及一种0.61kV及以下耐火1100℃矿物质电缆及其制备方法。
背景技术
随着目前石化装置规模越来越大，自动化水平越来越高，电缆在石化装置中的使用安全也引起了相关方越来越高的重视。在石化装置中，电缆用量大、规格品种多，分布广泛且辐照。在火灾防治方面，电缆又具有广泛性、易燃性、串延性的特点，一旦发生火灾，后果不堪设想。据近几年国内石化装置发生火灾的原因调查统计显示，有60%~70%的火灾由电气设备的事故引起，而绝缘大多数电气设备的问题都出现在电缆上。
针对电缆火灾的特点和原因以及石油石化生产高温、高压、易燃、易爆、强腐蚀、生产连续性等特点，需要专门为此研发一款防火系统用电缆。
在石油化工行业，对紧急控制线路有防火保护要求。美国石油学会标准API2218《石油和石化工厂的防火措施》中指出：如果用于启动紧急关闭设备（包括减压系统或隔离系统）的控制电气线路在火灾中可能会暴露在火场中，则该线路需要提供可抵御UL1709（快速升温火灾曲线）的15-30分钟的耐火保护。或与之等效的UL 2196标准（快速升温火灾曲线）15-30分钟的耐火保护。
针对电缆火灾的特点和原因以及石油石化生产高温、高压、易燃、易爆、强腐蚀、生产连续性等特点，需要专门为此研发一款防火系统用电缆。
石化防火系统要求电缆耐温1093度，保持线路完整30分钟，目前市场上的防火电缆的性能不能满足石化要求，因为铜的熔点是1083度，所以在此温度下铜护套已经融化，同时MgOH2也容易吸潮，在接头的地方容易产生故障，无法满足他们的需要。目前客户采用在氧化镁等矿物绝缘电缆，然后再进行采用二次防护的方式进行防火处理，比如采用防火隔离布进行包裹，这样安装敷设的整体成本非常高，敷设时空间的收到很大限制。
发明内容
本发明目的在于提供一种耐火1100℃矿物质低压电缆，该电缆防火效果优异，燃烧缓慢且具有低释放的烟量和毒性气体；同时，提供一种上述耐火1100℃矿物质低压电缆的制备方法。
为达到上述目的，本发明采用的技术方案是：一种耐火1100℃矿物质低压电缆，包括多根导体，多根导体呈环状分布，每根导体外侧依次设有耐火绕包带和绝缘层，所述多根导体外侧设有第一包带，所述第一包带与多根导体之间填充有无碱玻璃纤维填充绳，所述第一包带外侧依次设有隔氧层、耐火层与第二包带，所述第一包带与第二包带为无碱玻璃纤维带，所述第二包带外侧设有外护套；

6. 上述方案中，所述硅烷偶联剂选自甲基三甲氧基硅烷、γ-缩水甘油醚氧丙基三甲氧基硅烷或苯基三甲氧基硅烷。
本发明采用的制备方法技术方案是：一种上述耐火1100℃矿物质低压电缆及其制备方法，包括以下步骤：
S1. 将乙烯-醋酸乙烯共聚物树脂40~80份、聚烯烃弹性体30~50份、聚酯增塑剂15~30份和马来酸酐接枝聚乙烯2~4份，经高速混合机在高速搅拌状态下混合形成混合物；
S2. 降低混合机转速至500 rpm，在S1混合物中加入2-苯基苯并咪唑-5-磺酸1~3份、对甲氧基肉桂酸辛酯0.5~1.5份、钛酸四丁酯2~8份、三烯丙基异氰脲酸酯1~5份、硬脂酸异辛酯 1~3份、戊烷磺酸钠1~3份、十二烷基磺酸钠1~3份、二叔丁基过氧化物1~5份和硅烷偶联剂0.5~2份，混合均匀；

S4. 将S3中混合物料转入双螺杆挤出机中进行挤出造粒，螺杆转速250 rpm，得到隔氧层材料。
由于上述技术方案的运用，本发明与现有技术相比具有下列优点：

2. 本发明耐火1100℃矿物质低压电缆及其制备方法，其电缆结构简单，防火效果优异，燃烧缓慢且具有低释放的特性，同时采用玻璃纤维填充绳能有利于电缆的散热和载流量的提高。

上述实施例1~3和对比例1~2制得的特种矿物质电缆的产品性能如表3所示：
表3
Figure DEST_PATH_IMAGE006
表中总生烟量采用ISO 5660-1标准测试。
如表3的评价结果所示，本发明实施例中特种矿物质电缆氧指数高与对比例，总生烟量低与对比例，说明本发明制得的特种矿物质电缆燃烧缓慢，且释放的烟量极少，在火灾环境下，可以延缓电缆的损坏，同时极低的烟量释放可以降低环境中的毒性，可减少因吸入烟量过多而导致死亡的人数。
经过改进后的防火电缆结构简单，防火效果优异，生产效率明显高于普通防火电缆，采用玻璃纤维填充绳能有利于电缆的散热和载流量的提高，同时制造工艺较简单，施工中易于敷设和接头。本产品耐火性能能达到以下标准要求：
（1）BS 8491标准中的试验方法，每10分钟敲击一次，最后5分钟喷水，供火为360min，火焰温度为1093+40℃，试验结果满足其线路完整性试验要求。
（2）首次采用美标UL2196试验条件进行线缆测试，此产品试验即使是在美国也是非常严苛的，UL 2196 标准中“迅速升温曲线”（与 UL 1709 一致）作为试验检测温度条件下的线路完整性试验要求。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
