An expansive flame retardant for ammonium polyphosphate
Traditional expansive flame retardant is a kind of flame retardant system composed of acid source, carbon source and gas source. This kind of flame retardant system of flame retardant with high efficiency, no drop, low smoke, non-toxic, non-corrosive gas release characteristics, accord with the requirement of environmental friendly flame retardant system, is considered to be one of the developing direction of halogen-free flame retardant materials today.
Ammonium polyphosphate is an important part of the expansion type flame retardant, ammonium polyphosphate based expansion type flame retardant has a dual function acid source and gas source, because of high phosphorus content, nitrogen content, good thermal stability, nearly neutral, flame retardant effect is good wait for an advantage, has become a hot spot in the field of flame retardant technology research. However, the current production conditions are limited, and the polymerization degree of ammonium polyphosphate is only a few tens. Therefore, ammonium polyphosphate has a certain water solubility and has poor compatibility with polymer materials, which can not meet the corresponding mechanical performance requirements.
Therefore, the research on the expansion type flame retardant with polyphosphate mainly focuses on the following three aspects: (1) to study the new synthesis method and process, and improve the polymerization degree of polyphosphate; (2) surface modification (or microencapsulation) of the existing polyphosphate products; (3) develop the high efficiency coagent of expansive flame retardant. Purpose is to try to improve the efficiency of the expansion type flame retardant flame retardant, reduce cost and adding quantity, improve its compatibility with organic material, improve the flame retardant of resistance to dissolution in damp environment and decomposition temperature of ammonium polyphosphate in performance.
In this paper, a comprehensive review of the polyphosphate-based expansive flame retardant is studied in this paper. The co-effectiveness of expansive flame retardant. On raising the expansion type flame retardant flame retardant efficiency, to reduce the amount of such problems as the synergistic flame retardant research began in the 1990 s, after nearly 20 years of development, in view of the expansion type flame retardant system of effective agent coordination theory and applied research, the application domain expands unceasingly, also effectively promote the expansion type flame retardant system of the process of industrialization and commercialization.

Molecular sieve and other types of silicate. The molecular sieve is a class of SiO4- and alo4-tetrahedral crystalline silicon aluminate connected by oxygen Bridges.

The application of 4A molecular sieve to polyolefin flame retardant and the addition of molecular sieve to change the degradation process of the expansion carbon layer was found by the conical calorimetry analysis, so that the generated carbon layer was more stable.
Later, researchers at home and abroad conducted more in-depth studies on molecular sieves. Wei equal [4] using TGA and X-ray photoelectron spectroscopy (XPS) studies have shown that the ammonium polyphosphate flame retardant polypropylene (PP)/PER system, below 250 e, 4 a molecular sieve has the catalytic esterification of ammonium polyphosphate/PER system, accelerate the NH3, such as H2O in the gas phase, which affect the expansion behavior of ammonium polyphosphate/PER system, improved the matching of gas source and the melt viscosity, leading to the formation of porous carbon layer with high quality, while the latter is the key to improve the performance of polymer flame retardant.
At the high temperature, the 4A molecular sieve was decomposed into SiO2 and Al2O3 under the effect of ammonium polyphosphate/PER organic phase, resulting in the formation of si-p-al-c structure, which played a role in promoting carbon and stabilizing the carbon. Xia et al., which used to be used for the flame retarding treatment of ABS with 4A molecular sieve and ammonium polyphosphate/PER, obtained a similar conclusion.
