Flame retardant for polymer materials

Flame retardant for polymer materials

With the development and application of polymer materials, the research of new flame retardant and flame retardant technology is attracting more and more attention.

The two major topics of the study on the flame retardant of polymer materials are: (1) the design and synthesis of the new flame retardants (including flame-retardant copolymers) with multiple flame retardant effects, including the design and synthesis of the flame retardant copolymer. (2) flame retardant modification of macromolecular materials was studied by using radiation crosslinking and plasma modification grafting.

From the industrial application, it is still the leading direction of the flame retardant of the polymer materials. Halogen flame retardant is one of the largest organic flame retardants in the world, and in the 1970s and mid-1980s, it experienced a golden age of rapid development.

However, in recent years, the halogenated flame retardant has attracted a lot of attention in the application process, one is polybromodiphenyl ether itself and the pyrolysis of its flame retardant polymer and the toxicity of combustion products;

The other is a substitute for antimony oxide. So far, halogen flame retardant polymers, such as polyvinyl chloride (PVC), chloroprene rubber (CR) and high polymer materials with halogen organic flame retardants, are widely used. While these halogen flame retardant materials show superior flame retardation, they produce more smoke and toxic, corrosive gases (halogenated hydrogen) during combustion. This gas is one of the most dangerous factors in the fire, because of their diffusion speed is greater than the flame spread speed, get in the way of people in the fire evacuation and put out the work, make the life and property were seriously damage. From here, we do not lose face of the harmful effects of halogen flame retardants on the social environment and our lives. Therefore, we must pay attention to the research and development of halogen-free flame retardants.

The application of halogen and phosphorous flame retardants dates back to the early 19th century. Since the 1950s, the wide application of polymer materials has greatly improved the organic phosphorus flame retardants. In the early 1970s, organophosphorus flame retardants accounted for more than half of the total sales volume in the us, mainly used for the flame retardant plasticity of PVC resin. With polyurethane and the proposition of polyolefin and various engineering plastics flame retardant, research of new varieties of organic phosphorus flame retardants is active, is the trend of the development progress of thermal stability and flame retardant efficiency, a good performance in a series of halogen-free organic phosphorus flame retardants.

In the early 80 s, used on the expansion of the flame retardant coatings are introduced into polymer flame retardant, flame retardant system during this period, professor GCamino conducted a series of pioneering work in Italy, and establishing and perfecting the phosphorus and nitrogen as the main body of the expansion type flame retardant system and flame retardant mechanism theory. Since the 1980s, the study of ring and caged phosphate and its derivatives has attracted widespread attention.

Thus, people familiar with the flame retardant mechanism of flame retardants for polymer materials is an important content of flame retardant science, with phosphate as the source of acid and pentaerythritol as carbon source, melamine and so on as the expansion of the gas source of flame retardant mechanism of flame retardant system had certain were called, but due to different flame retardant system in the thermal oxidation reaction of polymer material, so the new flame retardant mechanism of flame retardant system remains to be further research.

Inorganic flame retardants such as Al (OH) 3, Mg (OH) 2, zinc borate and inorganic phosphorus compounds, many of inorganic flame retardant is packing type, they add large amount in the resin, so on the processing technology and the performance of the final products have a serious impact. In the 1990s, efforts to improve the performance of inorganic flame retardants were focused on the following four aspects: (1) particle size ultramicro refining and particle size distribution; (2) surface treatment; (3) less dust or dustless; (4) microencapsulation. Flame retardant mechanism of inorganic flame retardant

Al (OH) 3, Mg (OH) 2 flame retardant, flame retardant mechanism of Al (OH) 3 flame retardant referred to as "ATH, its consumption accounts for more than 80% of inorganic flame retardants, it has a flame retardant, smoke abatement, filling the three functions, non-volatile, non-toxic, corrosion small, low prices, has been hailed as a environment-friendly flame retardants. Mg (OH) 2 flame retardant also has the characteristics of the above, and Mg (OH) 2 Al (OH) 3 soft, in the mixing, molding processing equipment wear less, the thermal decomposition temperature of Mg (OH) 2 is higher, the mixing and processing temperature, pyrolysis and the influence from the quality of the product.
