Classification by type of flame retardant compounds

( 1 ) inorganic flame retardants : inorganic flame retardant main role is endothermic , the main varieties of aluminum hydroxide, magnesium hydroxide , red phosphorus , antimony oxide , molybdenum oxide , ammonium molybdate , zinc borate , zinc oxide , zirconium oxide, hydroxide, zirconium, etc. , in which aluminum hydroxide , magnesium hydroxide, red phosphorus , antimony oxide, the most widely used , in particular aluminum hydroxide, magnesium hydroxide can not only play a flame retardant , and can play the role of filling . They have good thermal stability , high efficiency , smoke suppression , resistance drops, fill safe, environmentally clean and cheap and other basic characteristics of the flame retardant material has been widely used . However, poor washability inorganic flame retardants , inorganic flame retardant because with strong hydrophilic polar , non- polar fabric with poor compatibility . Meanwhile, in order to achieve the required flame retardant fabric , a large amount of inorganic flame retardant added , the mechanical properties of materials and processing performance impact . Therefore, the conventional ultrafine inorganic flame retardants and nano research in recent years has been unprecedented attention. In addition, to reduce the effect of the same flame retardant amount of a flame retardant compound , flame retardant research synergies , but also flame retardant research direction in recent years .

( 2 ) organic flame : organic phosphorus-based flame retardants and halogen is divided into two series . The former use is very restricted. Halogen includes chlorine and bromine flame retardants two categories. However, chlorine-based flame retardants brominated flame retardants to be better than the poor , and this is difficult to produce because of the reason of free chlorine group . In addition, as bromide, corrosive and toxic thermal decomposition is relatively small , and therefore the small amount of chloride can be achieved using the same flame-retardant effect . Therefore, use of brominated flame retardants much more common . However, the use of the total situation, halogen flame retardant due to its decomposition products containing halogen acid , smoke big , harmful , etc, are gradually being replaced by other inorganic flame retardants .

Flame retardant textile multifunctional composite fabric finishing production process

Textile flame retardant properties, three methods can be obtained . One is for flame-retardant treatment of textiles , to reach the fire retardant purposes, but the flame retardancy and washing with time gradually increase the number of weakened or disappeared. For cotton, linen, wool and other natural fibers , can only be used after finishing methods, namely by adsorption deposition, chemical bonding , van der Waals forces and non-polar bonding and so on. Another method is the direct production of flame retardant fibers , textiles made from such fibers having a permanent flame retardancy. Polyester , polyvinyl alcohol and other synthetic fibers they use this method. The third method is based on the actual needs of the production , effectively combine these two methods produce flame-retardant textiles. In addition to considering its flame retardant fabric , but also take into account the toxicity of flame retardant products and melt , so as to minimize the human and environmental damage.
