Inorganic flame retardants in halogen-free flame retardants
Bacteria acid chloride with reactive monomer developed flame retardant unsaturated polyester, the research opens a new way in the field of flame retardant, then new bromine and (or) the reaction of the phosphorus flame retardant monomer appear constantly.
Since 1986, the debate on the toxicity and environmental issues of polybrominated diphenyl ether flame retardants has been carried out in the field of flame retardation, and the research and development of new substitutes for decabromodiphenyl ether have been promoted. However, with the enhancement of the fire retardant requirement and the enhancement of environmental awareness, the non-halogenation, anti-smoking and detoxification of flame retardants have become the frontier issues in current and future research fields of flame retardants. A great deal of research has been carried out in this field. The new flame retardant of the 21st century will be a compound flame retardant without halogen, high efficiency, low smoke, low toxicity and multi-function.
Aluminum hydroxide of inorganic flame retardants in halogen flame retardants: aluminum hydroxide [Al (OH) 3], which USES up to 40% of the total amount of flame retardant. Al (OH) 3 itself has the flame retardant, smoke and fill three functions, because it is not volatile, non-toxic, and can produce synergistic flame retardant action with a variety of substances, and is known as the inorganic flame retardant.
However, Al (OH) 3 has the disadvantage of adding a large amount, it usually needs to add 50% to show a good flame retardant effect. In order to overcome this shortcoming, it can be used to improve the granulation technology, to develop in the direction of ultrafine, to narrow the distribution of grain size. Improved coating technology to improve its dispersion in polymer; The method of macromolecular bonding method is used.

Halogen-free flame retardant of the inorganic flame retardant of magnesium hydroxide, magnesium hydroxide [Mg (OH) 2] is one of the rapid development of current add additive flame retardant, low smoke, non-toxic, can neutralize the acid in the process of combustion, corrosive gas, therefore is a kind of environment-friendly green flame retardant. The flame retardant mechanism is similar to that of Al (OH) 3. Compared with Al (OH) 3, the decomposition temperature of Mg (OH) 2 than that of Al (OH) 3 100 ￣ 150 ℃, can be used for processing the temperature higher than 250 ℃ flame retardant engineering plastics, and also promote the polymer into the role of carbon, but to achieve a certain amount of flame retardant effect, content need to be more than 50%, had a great influence on the performance of the material. To reduce the number of Mg (OH) 2 in the polymer content, one way is to Mg (OH) 2 particles is small, another method is to use coating technology of Mg (OH) 2 surface modification, to improve its compatibility with polymer.
Of inorganic flame retardants of halogen free flame retardant red phosphorus, red phosphorus is a kind of high performance flame retardant, flame retardant effect of high efficiency, smoke suppression and low toxic, but easy absorption of moisture, oxidation, and emit poisonous gas, dust explosion, dark red, so use is limited by a lot of. In order to solve these shortcomings, surface treatment of red phosphorus is the main research direction, and microencapsulation is the most effective method.
On the international market at present already has a variety of models of microscopic capsule red phosphorus products, domestic also carried out extensive research, the use of aluminum hydroxide, general metal sulfate, synthetic resin as the cyst wall material, but the market is not much. The future direction for the red phosphorus surface treatment: one is through the capsule material of cyst were modified, make it at the same time both the thermal stability, plasticizing and flame retardant, and other functions, development of multifunctional microscopic capsule red phosphorus flame retardants;
The second is to study the effective complex relationship between various flame retardants and red phosphorus flame retardants, and make microencapsulation, increase the flame retardant effect and improve the mechanical properties of materials. Third, red phosphorus has the effect of anti-smoking, and can be used to find the suitable anti-smoking agent to rematch. The fire suppression is more important than fire prevention and promotes the development of tobacco smoke technology.
Of inorganic flame retardants of halogen free flame retardant expandable graphite, expandable graphite is a new type of halogen-free flame retardant, it is made of natural graphite by concentrated sulfuric acid acidification treatment, and then after washing, filtering, drying, and then expanded made under 900 ￣ 1000 ℃. Expandable graphite expansion of initial temperature is 220 ℃ or so, begin to mild inflation in the 220 ℃ in 230 ￣ 280 ℃ rapidly expand, after volume can reach more than 100 times, even 280 times.
