| titleOfInvention | A kind of sulfonate flame retardant and preparation method thereof |
| abstract | The invention discloses a sulfonate flame retardant and a preparation method thereof. The structural formula of the flame retardant is as follows: The preparation method of the flame retardant: dissolve the alkali in the solvent N,N-dimethylformamide to make a solution with a concentration of 4wt% to 6wt%, and place the above solution in a container at -20 to -45°C under nitrogen gas Under protection, add benzaldehyde in an equimolar amount of the same base, and stir for 40-60 minutes; add raw material A in an equimolar amount of the same base to react, and stir until the reaction is completed. The structural formula of the raw material A is The above-mentioned R f is a fluoroalkyl group, a perfluoroalkyl group, a cyclofluoroalkyl group or a cycloperfluoroalkyl group; finally, the reaction temperature is lowered to room temperature, suction filtered, and the filter cake is dried at a constant temperature to obtain a sulfonate flame retardant; The reaction process and post-treatment of the method of the present invention are simple and convenient, and due to the special structure of the obtained flame retardant, the synergistic effect of the fluorine-containing compound and the aromatic sulfonate, the flame retardant performance is excellent, and it has good thermal stability and chemical stability . Adding to transparent PC will not change its transparency and gloss. |
