Aluminum hydroxide flame retardant is one of the fastest growing varieties of various types of materials additives. The purpose of the aluminum hydroxide flame retardant is to make the non-flame retardant material have the property of flame retardant, under certain conditions, it is not easy to burn or self-extinguish. As aluminum hydroxide flame retardant technology continues to progress, more and more types of aluminum hydroxide flame retardant, its performance has also been greatly improved. Today, flame retardant aluminum hydroxide flame retardants mainly include two types: one can delay the fire events and curb the spread of fire through a variety of ways to inhibit the combustion reaction, the other is to allow the material surface foam expansion And carbonized to form a protective layer. As peoples awareness of environmental protection and safety continue to improve, but also with the continuous development of new technologies and progress, the future of aluminum hydroxide flame retardant will have greater development, Xiao Bian today to tell you about the future of hydrogen oxidation Aluminum flame retardants the four major development directions, I hope we can help.

  1: Carbonization technology
  When the polymer is burned, it can achieve the purpose of flame retardant by producing carbon in the condensed phase. Carbon material in the surface of the thickness of 1 mm, you can withstand the high temperature of 743 ℃ without fire. In coatings, pentaerythritol, polyphosphazenes, and melamine can be used as a good carburizing agent, carbonization catalyst and blowing agent respectively. If the three by a certain percentage added to the paint, can be made of excellent performance aluminum hydroxide flame retardant coating.
  In addition, the use of easily carbonized polymer and can not be carbonized polymer blending, but also have a good flame retardant effect, such as easy to knot carbon polyphenylene ether and high impact polystyrene blend, because of the ability to knot carbon While greatly improving the flame retardancy; such as adding a small amount of gas phase fire extinguishing halogen-containing aluminum hydroxide flame retardant. Has a high flame retardancy. This carbonization technology will be widely used.
  2: smoke technology
  Since the addition of aluminum hydroxide flame retardant polymer can increase smoke, so smoke has become an important research topic. Smoke suppressants can effectively reduce the amount of smoke and smoke density additives, smoke suppressants Application is the focus of PVC, smoke compounds with the key compound is the most effective anti-smoking agent. In addition to the key and the octaaluminum oxidation outside, the newly developed foreign agent Zinc Molybdenum key is low toxicity and flame retardant excellent smoke suppressant. Due to the high price of aluminide, zinc borate, aluminum hydroxide, zinc, silicon, phosphorus and other compounds with a small amount of aluminum compounds are often added after compounding, which is a realistic way to solve the current smoke elimination problem.
  3: Microencapsulation technology
  Microencapsulation can prevent the migration of aluminum hydroxide flame retardants, improve the flame retardant effect, improve the stability, change the dosage form and so on.
In recent years, foreign countries have microencapsulated products, such as DuPonts Freon fluorocarbon polymer microencapsulated, and used in PVC, PP, as well as PVR (polyurethane), the effect is very good.
  4: Granulation
  Aluminum hydroxide, magnesium hydroxide, antimony oxide and other aluminum hydroxide flame retardants require the use of new technologies and new equipment to make it micronized to improve its fluidity, processability, and improve the flame retardant effect. The average particle size of aluminum hydroxide is required to reach 15m, while for antimony oxide, finer particle size is required. With Sb2O3 colloidal 0. 015 ^ 0 025m colloidal aluminum hydroxide flame retardant treated fiber, the resistance effect of the emblem increased by 8 times, and other properties also increased.
  The above is the future of the four major development directions of aluminum hydroxide flame retardants all the content, I hope we can help
