PP flame retardants

PP flame retardants

Along with the environmental protection increasing, phosphorus-containing flame retardants, because of the large amount of smoke release toxic and corrosive gases will gradually fade out areas of PP flame retardants, halogen-free flame retardants such as inorganic and expansion flame retardants will be the traditional important flame retardant PP.

Inorganic flame retardant is nontoxic and non-corrosive, without causing secondary pollution and high temperature. However, the addition of large quantities has a great influence on the processing performance and physical properties of the products. The surface modification and ultra-micronization model.the can remedy the defects, nano inorganic flame retardants will be the trend of development and application of PP flame retardants, new high-performance pollution-free nano inorganic composite flame retardant PP has a broad development space.

The expansion type flame retardant is very suitable for PP flame retardant due to the low smoke emission, the emission of gas harmless and the formation of carbon layer can effectively prevent the polymer melt. Therefore, the new type of IFR, which is constantly improving and improving, has a very broad development prospect.

Made up of traditional flame retardant synergistic flame retardant system integrated their excellent performance, good flame retardant effect, low cost, as well as flame retardant and smoke suppression, but also has some other special features, was very broad prospects. It can be recombined with flame retardant to reduce the amount of flame retardant and improve the flame retardant performance.

Nano-clay and carbon nanotubes will be the focus of future research of PP flame retardants, and the recombination of other traditional flame retardants will be the mainstream flame retardants for future new PP.

At present, any kind of flame retardant has its own defects. In the future, the flame retardant can greatly improve the flame retardant effect and improve the mechanical properties, thermal performance and other physical properties of PP. In addition, the flame retardants must meet the characteristics of non-toxic, odorless, pollution-free, simple manufacturing and rich sources of raw materials. Seen in this way, the preparation and distribution of traditional fire retardant mickey flame retardants is the most effective way to meet the above requirements, the distribution of flame retardants will be effective for future development of flame retardant, low smoke, non-toxic, green environmental protection, and low filling volume, low cost, multi-function type, fine, etc.

Because nanoparticles of quantum size effect, surface effect, interface effect, small size effect and superplastic characteristics of nano PP composite materials with unique mechanical properties and flame retardant properties, its outstanding characteristic is to use very few can give PP excellent physical and mechanical and flame retardant performance. In addition to nano inorganic flame retardants, lamellar clay and carbon nanotube PP have become the front-end products of PP material development.

PP layered silicate nanocomposites with compatible agent such as PP - g - MA will PP is inserted into the layered silicate of layered structure, the formation of nanocomposite increase is significant, the thermal stability of the thermal degradation reaction is hampered by greatly. In the process of combustion, a dense carbon layer is formed on the surface of the PP to improve the flame retardant performance, so as to reduce the amount of flame retardant and not reduce the flame retardant grade of PP.



Isopropylphenyl Phosphate(IPPP65) Uses:

Isopropylphenyl Phosphate, Flame Retardant IPPP65 Halogen-Free Phosphate Flame Retardant Plasticizer, Will Not Twice Pollute The Environment; In The Phosphate Ester Species Is A Viscosity, Phosphorus Content Is More Moderate A Model. This Product Is Colorless And Transparent, Good Compatibility, The Use Of Both Flame Retardant And Plasticizer, In The Flame Retardant And Plasticizer To Play A Balance Between The Role, But Also To Make The Processing Of The Same Material And Its Physical Properties.


Burning flame retardant mechanism is thought to be formed when the hard coke layer of insulation insulation low permeability to prevent the oxygen supply, thermal degradation of volatile matter of escape, such as the spread of the combustion heat make PP flame retardant performance.
IFR in PP layered silicate nanocomposites have a synergistic effect of clay, clay react with APP form aluminum phosphate ceramic structure and class, increase the carbon layer of protection, the material obtained has more excellent flame retardant properties.

Replace PER with PA6 as carbon agent composed of expansion type flame retardant PP with molten drops, the shortcomings of poor flame retardant effect, adding 4% of nano montmorillonite not only overcomes the drawback of flame retardant system drop, also make the tensile strength increased by 44.3%; In addition, the thermal stability of the materials has been improved, and the residual carbon rate has increased by 12%. SEM observation showed that the nano-montmorillonite addition enhanced the bonding force of the material interface, improved the material toughness and increased the capacity of the material.

Conventional carbon nanotubes flame retardant polypropylene PP flame retardants is hard to get ideal heat release rate, adding a small amount of carbon nanotubes in PP forming nanocomposites greatly improved after the flame retardant performance, even higher than that of organic clay nanocomposites flame retardant performance.

Carbon nanotubes have lipophilicity, dispersed in PP is much easier than clay, don't need to deal with and the use of solvents, organic modification does not produce organic modifier of poor thermal stability of PP flame retardant properties and mechanical properties of negative influence. In addition, its thermal degradation temperature is extremely high, it will not affect the processing process. Carbon nanotubes are environmentally friendly additives that do not harm the environment when they are recycled or discarded.
