▎ 摘  要

NOVELTY - Preparing metal organic frameworks (MOFs) required for graphene-modified flame-retardant aqueous polyurethane coatings and adhesives involves adding ammonium molybdate, nano silver, 1,5-naphthalene disulfonic acid to terephthalic acid and deionized water; stirring at 50-60 degrees C for 30-60 minutes, then reaction is stirred at 180-200 degrees C for 2-3 hours; filtering, washing with water, and drying to obtain MOFs, where mass ratio of ammonium molybdate, nano silver, 1,5-naphthalenedisulfonic acid, terephthalic acid and deionized water is (120-140):(6-7):(16-34):200:600. USE - Method for preparing metal-organic frameworks required for graphene-modified flame-retardant aqueous polyurethane coatings and adhesives. ADVANTAGE - The method helps in improving two important indicators of flame retardant and antistatic of polyurethane coatings and adhesives.
