Flame retardant without halogenation
Currently, halogen free, low smoke, low toxicity of environmentally friendly flame retardant has been the pursuit of goals, the world some flame retardant supply and application in recent years showed high enthusiasm, to no halogenated flame retardants for flame retardant halide and the development of flame retardant materials also spent a lot of power.
According to the analysis, the main varieties of flame retardant without halide are phosphor flame retardant and inorganic hydrate, and the phosphor flame retardants mainly include red phosphorus flame retardant.
Red phosphorus flame retardant is a kind of represented by red phosphorus flame retardants, is a kind of purple or slightly brown amorphous powder, for organic halogen free flame retardants, it has excellent thermal stability, not volatile, corrosive gas is not produced, flame retardant effect is good, good electrical insulation, etc. There is no toxicity hazard in the use, the addition quantity is small, indissolubility, melting point higher advantage. It can be widely used in many kinds of resin, unsaturated resin, hot melt adhesive, rubber, paint and other products flame retardant.
May be red phosphorus flame retardant effect in phosphorus flame retardants series, flame retardant efficiency is the highest, because the best red phosphorus theory is completely by elemental phosphorus, phosphorus content is 100%, while phosphorus content decreased after coated, but still far higher than other phosphorus compounds, together with coated red phosphorus moisture absorption after sex on the thermal stability and storage, transportation and processing more convenient, so red phosphorus in the phosphorus flame retardant series currently the most widely used thermoplastic materials, but its weaknesses first performance must be in red or black in color, it greatly limits its application in a lot of material.
Triethyl phosphate (TEP)
Triethyl phosphate(Flame retardants TEP) is mainly used as the high boiling point solvents,catalysts, plasticizers, flame retardants, ethylating agent, and organic peroxide stabilizer. And Triethyl phosphate(TEP) is widely used in medicine, pesticides, vinyl ketone, resins, hydraulic oil and other production areas. In Japan, 70% of this product is used in catalyst.

In addition, red phosphorus, although after coated, but limited to technology and the raw material of a variety of reasons, in the process of using or may inevitably lead to "fire", even more serious is the processing characteristics of the red phosphorus is poorer, and the compatibility of resin is not so good, processed material mechanics performance is very poor, coupled with the taste of the "smell" in the process of production makes it difficult to spread in the high-grade material.
Most of the organic flame retardants are toxic, corrosive, smoke and other shortcomings, and are more expensive. Inorganic flame retardants can compensate for these defects. General inorganic flame retardants often have both flame retardant and smoke elimination functions. Therefore, inorganic flame retardants have developed rapidly in recent years. In addition to the aforementioned Sb and P inorganic, there are also AL, Mg and B. An inorganic substance such as Mo and Zn. These inorganic flame retardants are mostly endothermic water loss, and the water vapor cools and dilutes the combustible gas, thus inhibiting the burning.
Aluminum compounds: main varieties are AL (OH) 3, when the ambient temperature of 190 ℃, AL (OH) 3 began to water loss. However, due to its low water temperature, it is not suitable for high polymer use. Due to its rich source of alumina and low price, it has triple functions of flame retardant, anti-smoking agent and filler, so it is still a promising flame retardant.
Boron compound: boron compound is a kind of flame retardant with a large number of varieties, including zinc borate, ammonium borate, boric acid, borax, barium borate, etc. The flame retardant mechanism has the same "membrane effect" as the same phosphorus compound as AL (OH) 3, and produces a layer of solid melt covering the surface of the polymer, producing flame retardant effect. Zinc borate and Sb2O3 amount and flame retardant effect can be any more than they are used alone, and smoke less, the price is low, the price of zinc borate is only about a third of Sb2O3, is an ideal Sb2O3 substitution.
Magnesium compounds: magnesium compound flame retardant is mainly Mg (OH) 2 is a newly developed flame retardant. Flame retardant mechanism of it, like AL (OH) 3, but the water temperature of 300-350 ℃, so more suitable for polyolefins. Mg (OH) 3 also has flame retardant and smoke suppression. Mg (OH) 2 treated with surface treatment agent has better flame retardant effect. If you add 47 to polypropylene. 6 Mg (OH) 2 and 1, processed by stearic acid. 1% NaCl - KCl solid melt, can meet the UL - 94 - VO standard.
