Organic boron flame retardant
At present, with flame retardant effect is one of the most common elements are: the first Ⅲ group of boron, Ⅳ B/zirconium, titanium Ⅴ A family of n/p/antimony and Ⅶ group of bromine/chlorine, etc. Among them, nitrogen and phosphorus are used in cellulose fiber, halogen and antimony are used in the durability of synthetic fibers.
The quality measure of flame retardant, in addition to the flame retardant performance, should consider itself is toxic, whether in the finishing process of poisonous gas produced, whether to produce a large amount of smoke and harmful gas in the combustion process. A variety of flame retardants are disabled by itself is toxic, such as three early (nitrogen heterocyclic propyl) phosphine oxide (APO, also known as TEPA), and recent ten pbdes (DEBDE) and hexabromocyclododecane (HBCD).
The flame retardant of phosphor is good in flame retardant properties. It is used for textile finishing with good washing resistance and long resistance to flame retardation, but it is easy to change the fabric color and the smell and toxicity. The flame retardant of halogen flame retardants is good, but it produces secondary pollution during use and combustion.
As new environmental regulations introduced gradually, organic boron flame retardants for its excellent flame retardant, low toxicity and smoke suppression characteristics is attention, accord with flame retardant no halide, no poison and smoke suppression of the development trend.
Boron resources are abundant, as early as the 18th century has used borax as a flame retardant, is the earliest inorganic boron flame retardant. However, organic boron compounds have limited application due to the instability of hydrolysis and the factors that can cause water washing and high price. However, compared with organophosphorous flame retardants, organic boron flame retardants are far less toxic and have good smoke suppression.
If the organic boron compounds and nitrogen, phosphorus, halogen, such as silicon into the same molecular structure in the synthesis of boron compound flame retardants, and try to improve the content of boron in molecular, on the one hand can improve the resistance of pure boron flame retarding agent hydrolysis stability and lower the price, at the same time also can reduce the toxicity of bromine and phosphorus flame retardant.
Nitrogen flame retardant when used alone, poor flame retardant effect, but combined with phosphorus compounds as flame retardant effects, such as inorganic ammonium phosphate and ammonium polyphosphate, phosphoramide, phosphite ester, phosphonic acid esters, such as organic class N - hydroxy methyl allyl dimethyl phosphite phosphonic acid amine (NMPPA) and four hydroxymethyl phosphonic chloride and urea grain preshrinking body (Proban) and so on.

Cresyl Diphenyl Phosphate(CDP) Use
This Product Is Flame Retardant Plasticizer, And Resin Compatibility, For Polyvinyl Acetal, Nitrocellulose, Polyvinyl Chloride, Natural Rubber And Synthetic Rubber; Can Also Be Used For Synthetic Lubricants And Hydraulic Oil; Substitutes For Triphenyl Phosphate. Applicable To Polyvinyl Chloride, Vinyl Chloride Copolymer, Polyvinyl Acetal, Nitrocellulose, Ethyl Cellulose, Cellulose Acetate Butyrate And So On.
Boron and nitrogen flame retardant compound, or through boron and nitrogen ligand chain formation of the compound flame retardant, can show good flame retardant performance. Their synergistic flame retardation is performed separately. When nitrogen fertilizer is heated to produce the non-combustible gases such as ammonia and nitrogen, carbon dioxide produced when adding cellulose for flame retardants are, these non-combustible gas when heated dilutes the oxygen in the air and polymer produced by combustible gases, and non-combustible gas generated, due to the endothermic reaction took part quantity of heat; At the same time, nitrogen traps free radicals, inhibits the chain reaction of high polymer, and ACTS as the scavenger of free radicals.
Boron-n composite flame retardant is the introduction of two elements of boron and nitrogen into the same molecular structure. The interaction of two elements in combustion can produce a better synergistic flame retardant effect.
Boric acid is a basic raw material for the synthesis of boron mixed atomic flame retardants. The main intermediates of this type of flame retardants are 2-allyl -1,3- oxycyclopentane, which is produced by the reaction of potassium borohydride with allyl alcohol in the presence of acetic acid. The compound is a heterocyclic ring of boron oxygen and is very stable and does not hydrolyze. The single and double - ring compounds of B - N ligand were obtained respectively with ethanolamine and diethylamine.
For the flame retardant with B/N coordination chain, the conventional rolling and baking finishing process is used for the flame retardant finishing of cotton fabric, the flame retardant effect is good, and the LOI value is 24.2 and 25.2 respectively.
Intermediate heating to 150 ~ 160 °, partial hydrolysis, often pressure distillation to remove allyl alcohol again; The two products, respectively 25.2 and 22.4 respectively, were respectively obtained after the reaction and heating of ethylene glycol with the ethylene glycol. The former containing boron is taller and shows better flame retardancy.
