TI  - Comparative Study on the Flame-Retardant Properties and Mechanical Properties of 
      PA66 with Different Dicyclohexyl Hypophosphite Acid Metal Salts.

AB  - Three metal salts of dicyclohexyl hypophosphite, namely dicyclohexyl aluminum 
      hypophosphite (ADCP), dicyclohexyl magnesium hypophosphite (MDCP), and 
      dicyclohexyl zinc hypophosphite (ZDCP), were synthesized. These flame retardants 
      were subjected to thermogravimetric analysis, and the results showed that ADCP 
      and ZDCP had higher thermal stabilities than MDCP. They were then separately 
      mixed with polyamide 66 (PA66)to prepare composite materials, of which the 
      combustion properties were determined by the limiting oxygen index method and 
      horizontal/vertical burning experiments. The mechanical properties of the 
      materials were further evaluated using an electronic universal testing machine. 
      The results showed that all the three flame retardants exerted a flame-retardant 
      effect on PA66, but the flame-retardant effect of MDCP was inferior to those of 
      ADCP and ZDCP. All the composites also showed similar mechanical properties. 
      Among the three flame retardants, ADCP had the best overall performance for raw 
      materials, showing good flame-retardant properties while maintaining the 
      mechanical properties of the raw materials. The optimal dosage of ADCP was 15 wt 
      %, at which a V-0 rating in the vertical burning test (UL 94 test) can be 
      obtained.
