Abstract
Description
(一)技术领域(1) Technical field
本发明涉及一种安全高效的含氟灭火剂组合物。The invention relates to a safe and efficient fluorine-containing fire extinguishing agent composition.
(二)背景技术(2) Background technology
哈龙灭火剂是一种卤化碳氢化合物的统称。“哈龙”灭火介质由于具有灭火高效、化学性质稳定等优点，而被广泛应用在民航、精密、贵重的火灾场景中。因在分解时卤代烃游离基与臭氧反应，造成严重的环境问题。因此，寻找新一代灭火高效、环境友好的“哈龙”替代产品成为了热点问题。因此一系列的哈龙替代物相继出现。Halon fire extinguishing agent is a general term for halogenated hydrocarbons. "Halon" fire extinguishing medium is widely used in civil aviation, precision and expensive fire scenes due to its advantages of high fire extinguishing efficiency and stable chemical properties. Serious environmental problems are caused by the reaction of halogenated hydrocarbon radicals with ozone during decomposition. Therefore, it has become a hot issue to find a new generation of "halon" substitute products with high fire extinguishing efficiency and environmental friendliness. Therefore, a series of halon substitutes have appeared one after another.
七氟丙烷作为典型的哈龙替代灭火剂，由于其不含有氯或溴，不会对大气臭氧层发生破坏作用且在释出后不会留下残余物或油渍，广泛的应用于精密电子设备及贵重物品的灭火场景中；但在常温常压下作为气体灭火剂仍需要封装在压力容器中进行运输，不方便且存在一定的安全隐患。Heptafluoropropane is a typical halon substitute fire extinguishing agent. Because it does not contain chlorine or bromine, it will not damage the atmospheric ozone layer and will not leave residue or oil stains after release. It is widely used in precision electronic equipment and valuables However, as a gaseous fire extinguishing agent under normal temperature and pressure, it still needs to be packaged in a pressure vessel for transportation, which is inconvenient and poses certain safety hazards.
对比哈龙灭火剂七氟丙烷灭火剂的灭火效率仅能达到哈龙灭火剂的二分之一，灭火效果并不理想且灭火过程中容易产生具有刺激性腐蚀性的HF气体，对灭火现场人员的生命安全存在危害。Compared with the halon fire extinguishing agent, the fire extinguishing efficiency of the heptafluoropropane fire extinguishing agent can only reach half of the halon fire extinguishing agent, the fire extinguishing effect is not ideal, and the irritating and corrosive HF gas is easy to be produced during the fire extinguishing process, which is harmful to the lives of the fire extinguishing personnel. There is a safety hazard.
综上所述，七氟丙烷在常温常压下为气体，在运输过程中存在安全隐患，且七氟丙烷灭火剂的灭火效果比起传统的哈龙灭火剂并无优势，灭火过程中产生的有害气体对现场人员的生命安全也会造成危害，这些缺陷对于哈龙替代灭火剂的推广使用而言是十分不利的。In summary, heptafluoropropane is a gas at normal temperature and pressure, and there are safety hazards in the transportation process, and the fire extinguishing effect of heptafluoropropane fire extinguishing agent is not superior to that of traditional halon fire extinguishing agent, and the harmful gas produced during fire extinguishing is harmful to the scene. The life safety of personnel will also cause harm, and these defects are very unfavorable for the popularization and use of halon alternative fire extinguishing agents.

对比例1：Comparative example 1:
七氟丙烷：100％。Heptafluoropropane: 100%.
下面通过杯式燃烧法对上述灭火剂组合物的最低灭火浓度进行测试。The minimum fire extinguishing concentration of the above-mentioned fire extinguishing agent composition is tested below by the cup combustion method.
将正庚烷倒入干燥塔中，连接干燥塔与燃烧杯将正庚烷导入杯中，调节液面与杯顶5mm～10mm。打开空气钢瓶，调节空气流量稳定在30L/min；点燃燃料，并预燃60s，在此期间将杯中的燃料液位调节至距杯顶1mm内；开始将实施例1～12中的灭火剂组合物通过蠕动泵分别通入油浴锅管路中(对比例1中使用七氟丙烷气瓶代替蠕动泵输送)，油浴锅温度设置为130℃使充分气化，并逐渐增加灭火剂流量，直至在该流量下1min内火焰熄灭，记录灭火剂流量及灭火时间，增加蠕动泵转速会增加灭火剂浓度，操作时注意这一增加量不要超过先前浓度的2％；下步实验前，应及时清除杯中燃料及附在杯上的残留物及烟黑。重复2次上述操作根据三次实验平均值，分别计算实施例1～12及对比例1中的灭火浓度：Pour the n-heptane into the drying tower, connect the drying tower and the combustion cup to introduce the n-heptane into the cup, and adjust the liquid level and the top of the cup by 5mm to 10mm. Open the air cylinder, adjust the air flow to be stable at 30L/min; ignite the fuel, and pre-ignite for 60s, during which the fuel liquid level in the cup is adjusted to within 1mm from the top of the cup; start to use the fire extinguishing agent in Examples 1-12 The composition was passed into the pipeline of the oil bath boiler through a peristaltic pump (heptafluoropropane gas cylinder was used instead of the peristaltic pump in Comparative Example 1). The flame is extinguished within 1 minute under this flow rate, record the fire extinguishing agent flow rate and fire extinguishing time, increasing the speed of the peristaltic pump will increase the concentration of the fire extinguishing agent, pay attention to this increase during operation not to exceed 2% of the previous concentration; before the next step of the experiment, it should be cleared in time The fuel in the cup and the residue and soot attached to the cup. Repeat the above-mentioned operation for 2 times and calculate the fire extinguishing concentration in Examples 1 to 12 and Comparative Example 1 respectively according to the average value of three experiments:
灭火浓度计算公式：The formula for calculating the fire extinguishing concentration is:
式中：C为含氟灭火剂组合物灭火时的体积分数，即灭火浓度；In the formula: C is the volume fraction when the fluorine-containing fire extinguishing agent composition is extinguished, that is, the fire extinguishing concentration;
V为含氟灭火剂组合物气化后的体积流量，L/min；V is the volumetric flow rate after gasification of the fluorine-containing fire extinguishing agent composition, L/min;
Vair为空气的体积流量，L/min。V air is the volume flow rate of air, L/min.
实验结果见表1：The experimental results are shown in Table 1:
表1Table 1
由表1数据可知，对比对比例1与实施例1～12可知通过加压混合得到的含氟灭火剂组合物其灭火浓度由7.59％最低降低到了4.23％降幅达到了40％以上，这就表明了随着灭火助剂与稳定剂的加入七氟丙烷灭火剂的灭火效果得到了极大的提升；实施例1～3与实施例4～6相比可发现加入灭火助剂选用全氟三乙胺对灭火浓度的降低效果要优于2-BTP，这是由于全氟三乙胺与七氟丙烷的相容性更好因此混合制得的灭火剂组合物具有更好的协同作用；实施例1～3与实施例7～9对比可发现稳定剂选用全氟三丁胺灭火效果会优于全氟三丙胺，其原因是全氟三丁胺在高温下更易裂解会产生更多的活性自由基参与到灭火反应中。As can be seen from the data in Table 1, comparing Comparative Example 1 with Examples 1 to 12, it can be seen that the fire extinguishing concentration of the fluorine-containing fire extinguishing agent composition obtained by pressurized mixing has been reduced from 7.59% to 4.23%, and the decline has reached more than 40%, which shows that Along with adding fire extinguishing aid and stabilizing agent, the fire extinguishing effect of heptafluoropropane fire extinguishing agent has been greatly improved; Embodiment 1～3 can find that adding fire extinguishing aid selects perfluorotriethylamine for use compared with embodiment 4～6 The reduction effect of fire extinguishing concentration is better than 2-BTP, and this is because the compatibility of perfluorotriethylamine and heptafluoropropane is better, so the fire extinguishing agent composition mixed has better synergy; Embodiment 1～3 and From the comparison of Examples 7 to 9, it can be found that the fire extinguishing effect of perfluorotributylamine as a stabilizer is better than that of perfluorotripropylamine. The reason is that perfluorotributylamine is easier to crack at high temperature and will produce more active free radicals to participate in fire extinguishing Reacting.
