| titleOfInvention | A kind of preparation method of hygroscopic flame retardant modified PTT polyester |
| abstract | The invention relates to the field of polyester materials, and the invention discloses a preparation method of a hygroscopic flame-retardant modified PTT polyester, comprising: 1) esterification reaction: mixing terephthalic acid with 1,3-propylene glycol, isosorbide and a The burning agent undergoes esterification reaction to generate polymerized monomer; 2) Polymerization reaction: adding a catalyst to the polymerization system comprising the polymerized monomer obtained in step 1), a polymerization reaction occurs, and a hygroscopic flame-retardant modified PTT polyester is obtained. In the present invention, before the polymerization reaction, isosorbide and flame retardant are added. Under the premise of excellent tensile strength and breaking strength, the PTT polyester obtained by the invention has improved hygroscopic performance and a higher oxygen index value, thereby improving the flame retardant effect of the PTT polyester and enriching its use. scope. |
