| titleOfInvention | A kind of anti-aging self-flame retardant PET masterbatch and preparation method thereof |
| abstract | The invention discloses an anti-aging self-flame retardant PET composite material and a preparation method thereof, comprising the following raw materials in parts by mass: 100 parts of terephthalic acid, 90 to 120 parts of ethylene glycol, 25 to 35 parts of pyromellitic acid, and amino acids. 5-15 parts of guanidine sulfonate, 3-7 parts of aminotrimethylene phosphonic acid, 2-4 parts of dicyandiamide, 2-3 parts of catalyst, and 20-30 parts of functionalized layered double metal hydroxide; preparation method thereof S1: After mixing terephthalic acid, ethylene glycol and catalyst, under the condition of 0.1MPa and 200～220℃, pre-esterify for 2～3h, then add pyromellitic acid, guanidine sulfamate, Amino trimethylene phosphonic acid and dicyandiamide are heated to 280-290°C and stirred for 1-1.5h; S2: vacuumize the S1 reaction system to 50-100Pa, perform polycondensation reaction at 270-280°C for 3-6h, and then add functional The layered double metal hydroxide is formed, and the reaction is kept stirring for 1 to 2 hours, and then cooled and solidified. By embedding the flame-retardant substance in the PET molecular chain, the method of the invention endows the PET material with self-flame-retardant properties, avoids the problem of phase delamination, and greatly improves the mechanical strength and mechanical properties of the PET material. |
