| Zusammenfassung: | The invention relates to a preparation method of weather-aging-resistant polyamide resin, which comprises the following steps of: mixing an end-capping reagent with an aromatic compound containing a binary active group and water according to a molar ratio of 0.99-1.01, mixing the end-capping reagent with organic silicon containing the binary active group and water according to a molar ratio of 0.99-1.01, mixing 1, 6-hexamethylenediamine, 1, 6-adipic acid and water according to a molar ratio of 0.99-1.01, and stirring to obtain the weather-aging-resistant polyamide resin. Uniformly mixing the obtained solution to obtain a mixed polyamide salt D solution; and heating the polyamide salt D solution to obtain a polyamide melt E, carrying out underwater granulation on the polyamide melt E through a granulator, and drying to obtain the weather aging resistant polyamide resin. The weather-resistant polyamide resin disclosed by the invention can be used as an engineering plastic material to prepare products with requi |
