Development trend of polystyrene flame retardant
With the increasing demand for environment protection, halogen flame retardant due to large amount of smoke, toxic and corrosive gas will gradually fade out of polystyrene flame retardant field, emphasizes on the use of halogen-free flame retardants such as inorganic flame retardant and intumescent flame retardant will become the development trend of flame retardant polystyrene.
Inorganic flame retardant has the advantages of no toxicity, no corrosion, no pollution and high temperature resistance when burning. However, the addition of inorganic flame retardants has a great influence on the processability and mechanical properties of polystyrene. The above defects can be solved by surface modification and micro modification. Nano inorganic flame retardant will become the development trend of inorganic polystyrene flame retardant.
Intumescent flame retardant is a hot topic because of its advantages such as less smoke, no harmful gas and carbon layer. It is very suitable for polystyrene flame retardant. Therefore, the continuous improvement and improvement of the new intumescent flame retardant is also one of the development trends of polystyrene flame retardant.
The synergistic flame retardant system composed of traditional flame retardant has good properties, good flame retardant effect, low cost, flame retardant and smoke suppression, and some other special functions, and the prospect is still very broad. It can reduce the amount of flame retardants and improve the flame retardancy of polystyrene by compounding with other flame retardants.
Nano clay and carbon nanotubes will be the focus of future research direction of polystyrene flame retardants, and other traditional flame retardants will be the mainstream of the future flame retardant.
At present, any kind of flame retardant has some defects, the future needs of polystyrene flame retardant will not only greatly improve the flame retardant performance, but also improves the mechanical properties, thermal properties and other physical properties. In addition, the flame retardants need to meet the characteristics of non-toxic, odorless, pollution-free, simple manufacturing, rich raw materials and so on.
The compound flame retardant developed in the future will have the characteristics of high efficiency flame retardant, low smoke, non-toxic, green environmental protection, low filling capacity, low cost, multi-function, fine type and so on. Therefore, the future should be in-depth study of surface modification technology of inorganic flame retardant solution, dispersion and interface bonding and other issues to reduce the impact of the deterioration of the mechanical properties of the material, the further development of new intumescent flame retardant and fire retardant synergistic agent.
Tris(2-chloroisopropyl)Phosphate(TCPP)
Cas No:13674 -84-5
HS Code HS: 29199000
The most important indicator of product:
colorless transparent liquid, moisture ≤ 0.1, Acid value ≤ 0.1, Chroma ≤ 50, the phosphorus content: 9.4 ± 0.5
Raw materials: phosphorus oxychloride and epichlorohydrin.
Belong to several categories of dangerous goods:
Currently Tris(2-chloroisopropyl)Phosphate TCPP general cargo exports are not dangerous.
The product is used for the soft / hard polyurethane foam, with thermal and hydrolytic stability good, especially suitable for ASTME84 (Level 11) foam, with low viscosity unsaturated polyester resin in low temperature application and phenolic plastics at. This product is also used to grab the foam sealant and sheet production. For polyvinyl chloride, polystyrene, phenolic resin, acrylic resin and rubber, coating, flame retardant, also used for soft and hard polyurethane foam, epoxy resin, polystyrene, cellulose acetate, ethyl cellulose tree and phenolic plastics, polyvinyl acetate and gun type foam sealant production. Particularly recommended for rigid polyurethane foam has excellent thermal and hydrolytic stability is particularly suitable for ASTM84 (II), compound for polyurethane foam and unsaturated resin and phenolic plastics.
Using polystyrene -g-MAH as the compatibilizer, insert the polystyrene to lamellar structure of layered silicate, the thermal stability of nano composite materials formed by the increased thermal degradation reaction has been greatly hindered, the combustion process will form a compact carbon layer on the surface, improve the flame retardant properties of composite materials. The flame retardant mechanism is generally believed that the formation of combustion heat insulation, insulation, low permeability and hard coke layer prevents the external oxygen supply, thermal degradation of the generated volatiles escape, the combustion heat diffusion of the flame retardant properties of polystyrene was improved.
IFR has a synergistic effect with clay, and clay reacts with ammonium polyphosphate to form aluminum phosphate and ceramic like structure, which increases the protective effect of expanded carbon layer and makes polystyrene more excellent flame retardant. By using PA6 instead of PER as a charring agent composed of IFR with droplet, flame retardant effect bad, adding 4% nano montmorillonite not only overcomes the shortcomings of the droplet, the tensile strength increased by 44.3%; in addition, also improves the thermal stability of polystyrene, the carbon residue rate increased by 12%. Nano montmorillonite can enhance the interfacial bonding force, improve the toughness of the material, and play a role of compatibilization.
Qu Yingjun and other flame retardants were modified with IFR as flame retardant, montmorillonite as synergistic agent and polystyrene -g-MAH as compatibilizer. The results showed that the addition of MMT reduced the flame retardancy and mechanical properties of the polystyrene /IFR system, but solved the smoke phenomenon in the combustion system to some extent. When the amount of IFR is 35 phr, the vertical combustion performance of the system reaches FV-0 grade, and the combustion residue forms a dense carbon layer, which has good mechanical properties and processability.
The conventional flame retardant polystyrene is difficult to obtain ideal heat release rate, adding a small amount of carbon nanotubes in polystyrene and its flame retardant properties have greatly improved, even higher than the flame retardant properties of polystyrene / organoclay nanocomposites. Carbon nanotubes are lipophilic, dispersed in polystyrene than clay much more easily, without modification and the use of organic solvent, not because the poor thermal stability of the organic modifier agent negative effect on flame retardancy and mechanical properties of polystyrene. In addition, the thermal degradation temperature of carbon nanotubes is very high, which will not affect the processing process. Carbon nanotubes are environmentally friendly additive flame retardants, which do not harm the environment when they are reused or discarded.
Polystyrene / carbon nanotube composites were prepared by solution method, Li Wenhua et al. It is found that the carbon nanotubes have heterogeneous nucleation, and the carbon nanotubes are refined, and the thermal stability and flame retardancy of the composites are improved obviously.
