Phospho-silicon flame retardant
Silicone flame retardants is a rising star of the flame retardant family, halogen after its development and phosphate flame retardants, it by its excellent flame retardancy, low burning rate, low heat, prevent drip), good workability (liquid), especially friendly to the environment (low smoke, low carbon monoxide generation) and the attention of people.
However, when used in single use, the flame retardant of silicon is often poor in compatibility with the polymer and high price. When phosphorus - silicone flame retardants used jointly, at high temperatures, phosphorus catalytic contributed to the formation of carbon and silicon, increase the thermal stability of the carbon layer, thereby phosphorus, silicon flame retardant synergistic flame retardant effect, improve the flame retardant efficiency, decrease the cost of application.
2004, Peng Zhi han reported a new structure for pure cotton fabric flame retardant processing of phosphonic acid ester flame retardant containing silicon SPFA, the phosphine flame retardants can improve the coal rate of materials, especially for the oxygen of the high polymer, such as cellulose and rigid polyurethane foam plastics, etc.) in particular.
In 2006, Zhang et al. synthesized the symmetric-structured double - ring cage - flame retardant CPQS with silica and pentaerythritol. Thermal analysis results show that the double loop cage four ligand silicon at 700 ℃ of weightlessness is only 19.98%, and carbon layer been compacted layer. Applying it to epoxy resin, 20% of the added amount can bring the LOI value to 26.5 and realize the ul94v-0, and the thermal stability of the resin has also been improved.
In 2007, wu Dan et al. reported the expansion of phospho-silicon flame retardant in the following structure. Compared with traditional flame retardants, it contains no halogen and has three elements of expansive flame retardant. The DOPO structure is used as an acid source to overcome the disadvantages of traditional flame retardant.
In 2009, Ding et al. synthesized the structure symmetric phosphorous, silicon flame retardant dopo-tmds and dopo-dmdp, and applied it to epoxy resin. The results show that the two phospho-containing flame retardants can improve the thermal stability, mechanical properties and flame retardant properties of the resin. Especially the flame retardant performance, when the phosphorus content in the resin is 2%, the LOI value can reach 32-33, and the vertical combustion achieves v-0.

In 2010, Hu et al. synthesized P (dopo-vtes) from DOPO and ethylene triethoxysilane. Thermo-gravimetric shows P (DOPO - VTES) at 700 ℃ carbon residue rate is as high as 86.31%. The value of the LOI can reach 32.8 when the added amount is 5%, and the vertical combustion reaches v-0 at the time of the 2% montmorillonite.
With the increase of fire safety standards and the rapid growth of plastic production, the production and sales of global flame retardant are increasing at a rate of 3.0%~ 7.0%. In addition, people's increasing attention to environmental protection, the dominance of halogen flame retardants has been gradually shaken, which provides a greater development space for phosphor flame retardants.
However, if any flame retardant is widely used, it must be technically mature and economically feasible. Although there are many new kinds of phosphorus flame retardants developed and reported, they have not yet entered the industrial production and application fields. Especially the essential phosphor flame retardants, due to the complex preparation process and high production cost, make it difficult to industrialize. Compared with halogen flame retardants, some phosphor flame retardants can't match the efficiency and price. Therefore, the existing problems of phosphorus flame retardants need to be further worked.
In 2007 Schfer et al. reported on a DOPO structure called DPPO. DPPO reacts with the phenolic epoxy resin den-438, or with hydroxylation of hydrogen peroxide and formaldehydes, and den-438 reaction, and three types of phosphorous epoxy resin based on DPPO structure are synthesized.
For comparative study of Schfer etc are synthesized by DOPO phosphorous type phenolic epoxy resin, curing with DDM, DPPO epoxy curing the LOI value is slightly lower than curing, DOPO structure between 26.5 ~ 31.1, may be associated with phosphorus content, but DPPO curing or showed good thermal stability and high carbon residue rate.
