| titleOfInvention | Quaternary phosphonium salt flame retardant and synthetic method and application thereof |
| abstract | The invention provides a quaternary phosphonium salt flame retardant and a synthesis method and application thereof, wherein the method comprises the following steps: the method comprises the following steps of carrying out synthesis reaction on trihydroxyethyl isocyanurate and a sulfonyl chloride compound III to obtain an intermediate product II, and then reacting the obtained intermediate product II with triphenylphosphine to obtain a quaternary phosphonium sulfonate compound with a triazine ring structure, namely the quaternary phosphonium salt flame retardant I. The flame retardant is prepared by taking trihydroxyethyl isocyanurate, different substituted sulfonyl chloride compounds and triphenylphosphine as raw materials through two-step reaction, and the obtained flame retardant has good thermal stability and excellent flame retardant effect in polycarbonate; the synthesis operation is simple, the raw material price is low, the synthesis condition is mild, and the yield is high; the introduction of halogen ions is avoided, and hectogram preparation can be carried out; the obtained PC flame-retardant composite material UL-94 can reach V-0 grade only by adding a small amount of flame retardant. |
