| titleOfInvention | Preparation method of phosphorus-based organic silicon type flame retardant |
| abstract | The invention relates to the field of fine chemical engineering, in particular to a preparation method of a phosphorus organic silicon type flame retardant; in the method, under the action of a catalyst, p-aminophenyl trimethoxy silane and diethoxy siloxane in a certain proportion are fully reacted in a solvent; and then distilling the water content of the reaction liquid and unreacted monomers to obtain a mixed solution, dropwise adding quantitative phosphorus oxychloride into the mixed solution, and extracting a solvent after the reaction to obtain the phosphorus-based organic silicon type flame retardant. The invention has the advantages of simple and easily obtained preparation process, obvious flame retardant effect and less addition amount, thereby having the advantage of lower cost. |
