The development of flame retardant technology with the development of synthetic polymeric materials

Polymer materials according to the source can be divided into natural, synthetic and synthetic polymer materials. In 1907 baekeland and his assistant, invented the phenolic resin, marked the beginning of human application of synthetic polymeric materials. Because of excellent performance and production application of low investment, synthetic polymer materials got rapid development in just a few decades, electrical and electronic products, high-rise buildings, aircraft, automotive and transportation, decoration and other industries heavy use of natural or synthetic polymer materials, make high polymer material and metal, ceramic and three kinds of one of the most important material.

 

Due to the high polymer material has the characteristics of large molecular weight, high carbon content, and make the most of flammable, combustible, and combustion of polymer materials have very strong toxicity, it also becomes the important reason which cause the loss when the fire broke out, so as to promote the development of the flame retardant technology.

 

Flame retardant technology since 1908 G.A.E n - with natural rubber and chlorine reactions such as gelard with flame retardant chlorinated rubber, pioneered by chemical methods of flame retardant polymer first, especially the demand of polymer industry is developing rapidly in recent 40 years, flame retardant technology rapid development, has developed many efficient and new type of flame retardants.

 

Flame retardants are used to improve the material flame resistance, namely to stop the spread of the material is of ignition and flame inhibition agent. According to the fire retardants and fire retardant base material, the relationship between flame retardants could be divided into two types: add type and reaction type. According to flame retardant element types, often divided into phosphorus-containing flame retardant, organophosphorus, halide phosphorus, nitrogen, phosphorus, magnesium, inorganic phosphorus - nitrogen, antimony, aluminium, magnesium, inorganic phosphorus, boron, aluminum, etc.

 

Flame retardant by endothermic, covering the role in the process of combustion, inhibition of chain reaction and decomposition smothering action principle, non-flammable gas to make flammable polymer materials noncombustible, flame retardant, self-extinguishing, or its flame propagation speed slow, heat release and smoke release rate is reduced, thus effectively improve the fire safety in polymer material application.

 

With the continuous development of science and technology and the application of polymer materials, flame retardant technology research also constantly promote in-depth, its scope has covered the natural polymer materials such as wood, fabric, fiber, synthetic polymer materials such as plastic, rubber and asphalt half a synthetic polymer materials.
