摘要

The effect of Cloisite® 20 organoclay content on fire retardancy, mechanical and chemical properties of dried films of halogen-free alkyd resins synthesized from Cloisite® 20 organoclay and dehydrated castor oil (DCO) were investigated. Structural elucidation of the raw and the fire-retardant resins was confirmed through Fourier transform infrared spectroscopy instrumental techniques. The DCO modified alkyd resin macromolecule was synthesized through alcoholysis-esterification interface using glycerol, phthalic and maleic anhydride. Eight samples of fire-retardant resin were produced. Samples Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ and Ⅵ contain 0, 2, 4, 6, 8 and 10% by mass of Cloisite® 20 organoclay, respectively. Samples Ⅶ and Ⅷ contain 4% of weight of Cloisite 20 with 100% PA and 3:1 ratio of phthalic anhydride and maleic anhydride, respectively. The fire retardancy was evaluated using Westgate vertical match test. Itwas found that fire retardancy increases with increases in Cloisite® 20 contents without any noticeable effect on chemical resistance, but certain drawbacks with adhesive and gloss properties were observed. The best result was observed with sample Ⅳ which contains 6% by weight of Cloisite® 20 and showed excellent fire-retardant properties with adhesion, gloss and hardness properties of 5B, 80 and 1.8 Kg, respectively. The infrared (IR) spectra band at 1035, 921, 792, 683 and 556 cm~(−1) of Si-O-Si and O-Si-O stretching confirms the successful grafting of the organomodifier.
