Paragraph 0034, (2016/12/01)
The invention relates to a phosphorus-sulfur-halogen synergistic flame retardant plasticizer compound and a preparation method thereof. The structure of the compound is as shown in the following formula (as shown in the description), wherein C3H6X is CH3CHCH2Cl, CH2CHClCH3, CH2CH2CH2Cl, CH3CHCH2Br, CH2CHBrCH3 or CH2CH2CH2Br. The preparation method comprises the following steps: enabling reaction of dimethyl benzene thiophosphate and halohydrin under existence of a catalyst or taking reaction of dimethyl benzene thiophosphate dihalide and epoxypropane in an organic solvent; carrying out purification treatment to obtain the faint yellow sticky fluid phosphorus-sulfur-halogen synergistic flame retardant plasticizer. The flame retardant disclosed by the invention contains phosphorus, sulfur and halogen three flame retardant elements, so the flame retardant is good in flame retardancy; furthermore, the flame retardant plasticizer is good in plasticization and applicable for PVC, polyurethane, epoxy resin, unsaturated resin and other materials; the preparation method is simple in technology, high in yield, free of hydrogen chloride pollution, low in equipment investment and easy for large-scale production.
