在阻燃剂无卤化呼声越来越高的今天,N-P系阻燃剂成为令人关注的热点之一。BL-环保阻燃剂属于N-P系阻燃剂,其主要原料与聚磷酸铵一样是磷酸与尿素,但因为其特殊的合成工艺使它不同于普通的聚磷酸铵。对BL-环保阻燃剂的生产工艺、生产设备及成本等几个方面分别进行了阐述。该阻燃剂具有制备简单、能耗低、生产设备投资少、成本低、与环境友好等优点,符合世界阻燃剂的发展趋势。BL-环保阻燃剂可用于生产阻燃实木、阻燃人造板和阻燃纺织品,并在森林草原防火上得到了创新应用。
In the non-halogenation of flame retardants increasingly high today, N-P flame retardants become one of the hot spots. BL-green flame retardant belongs to N-P series flame retardant. Its main raw material is phosphoric acid and urea like ammonium polyphosphate, but it is different from common ammonium polyphosphate because of its special synthetic process. On the BL-green flame retardant production technology, production equipment and cost, and several other aspects were described. The flame retardant has the advantages of simple preparation, low energy consumption, less investment in production equipment, low cost and environment friendliness, which is in line with the development trend of world flame retardants. BL-environmentally friendly flame retardant can be used for the production of flame-retardant wood, flame retardant wood-based panels and fire-retardant textiles, and in the forest grassland fire has been innovative applications.
