Flame retardant mechanism: The flame retardant can be divided into gas flame retardant and aggregated flame retardant. In general, the flame retardant is a substance containing phosphorus or halogen. For gas flame retardants, the author explains its flame-retardant mechanism as an example of phosphate (TMP). During the heating, TMP evaporates and exposes the flame, and the gasification TMP decomposes the phosphorus-containing free radical. Phosphorus-containing free radicals can quickly remove hydrogen free radicals, cut off the combustion chain reaction, thereby inhibiting combustion. For fluorinated flame retardants, the gasified fluoride decomposes fluorine-containing free radicals, eliminating hydrogen radicals. For agglomerated flame retardants, phosphatic-decomposed phosphoric acid can quickly produce dense combustion products in the interface, slow down heat transfer and continuous gasification decomposition of the agglomerate, thereby inhibiting combustion. In 2000, various industry engineers prepared materials and concentrated flame retardant decomposition products to cut the hydrogen-free radicals ** reaction to achieve flame retardant purposes. Phosphorus flame retardants are used in many varieties of paper flame retardant. The phosphorus resistance agent for the papermaking industry is a metadymmonium hydrogen, which is currently widely used in the development of important flame retardant polymmonium in recent years. The molybdenum compound has an increased carbonization of molybdenum compound aggregation phase. The molybdenum compound can be used with a halogen flame retardant, improve the oxygen index, and has a good effect on the phlegm. Commonly used molybdenum compound flame retardant inhibitors have oxide (MoO3) and ammonium octamolybdate (AOM). For PA66 materials with higher flame retardant requirements, single flame retardants usually do not meet the requirements, and the synergistic effect of composite flame retardants will have a larger market; Nano-flame retardants include inorganic oxides, hydroxides, laminated silicates, clays, montmorillonite, carbon nanotubes, but still have certain limitations in terms of flame retardant effects or mechanical properties. Two or more flame retardants are also research trends in flame retardant materials. Due to the low aluminum base content, when the flame-retardant wire and cable coating are used, it does not affect the electrical performance of the material, and the heat is absorbed by the flame retardant to reduce the paper temperature, thereby exerting the flame retardant effect. Zinc borate can be used singly or in combination with other flame retardants. Commonly used surface treatment agents are silane coupling agents, sodium stearate, and the like. The principle is to improve the surface activity of aluminum hydroxide and magnesium hydroxide of the inorganic flame retardant by chemical bonding, thereby increasing compatibility with the matrix resin. Surface treatment mainly includes dry modification and wet modification. Dry modification is to add a small amount of inert solvent and the coupling agent directly with the flame retardant, and then heated the coupling agent; the wet method and the dry method are the difference in dissolving the flame retardant and the coupling agent in the solvent, coupled After the solvent is separated, the modified flame retardant is obtained. In contrast, dry modification is simple. From the perspective of reducing costs, dry modification is generally used as a business production, but will still increase costs. It is to find a simpler method for the development direction of the current flame retardant surface modification, such as mixing the coupling agent with the matrix resin and the flame retardant to make it well in combination with various ingredients during mixing. Good effect. (2) Sucking effect: The inorganic flame retardant in the thermally modified polystyrene plate is thermally decomposed to produce water, and the water is evaporated in high temperature, inhibiting the temperature rise of the polymeric material, producing a flame retardant effect. When choosing an inorganic flame retardant, our company preferred low decomposition temperatures and releases a lot of water-free flame retardants. Recently, some flame retardants are also prohibited from using some flame retardant pentabromodiphenyl ether and octabrominated ether. For newly developed flame retardant products, the impact of the human health LD>Flame retardant plasticizer TCPP factory Phosphoric acid tris(2-chloro-1-methylethyl) ester manufacturer  safety and environment has been fully studied and evaluated. It provides more detailed information for production and use. On the one hand, people are working hard to improve the level of security of existing flame retardants and flame retardant materials. On the other hand, they are committed to developing new environmentally friendly flame retardants (such as halogen-free flame retardants) and gradually promotes its use (eg Global halogen-free flame retardant polypropylene has reached 20% of the total amount of flame retardant polypropylene). It is believed that there is more fires in the new halogen-free flame retardant high-soluble protection, and the agent plastic mainly has LD accuracy, but the liquid retardant in five periods should be changed. Advantages: The content of the silicone flame retardant in the PC is generally below 4%, and the modified material does not lose the physical mechanical properties, intensity and toughness retention ratios of the original PC resin in more than 90%. The processing stability of the silicone flame retardant PC is comparable to the pure PC resin, which can be repeatedly recovered. The thermal deformation temperature of the silicone flame retardant PC is basically maintained in the original PC resin level.Tris(1-chloro-2-propyl) phosphate supplier
