摘要：
In order to protect the environment and utilize renewable resources, maleopimaric acid epoxy methyl acrylate (MREMA) and polyurethane acrylate (PUA) were synthesized. According to mass 1∶1 proportion of MREMA and PUA, the nanocomposites of MREMA/PUA with different ratio of hydroxyl-containning carbon nanotubes (HCNTs) were prepared. Structures of MREMA and PUA were characterized by FT-IR and NMR. The curing process, dynamic mechanical properties and thermal stabilities and properties of coating films for nanocomposites were characterized by DMA, TGA, TEM and film testers. The results show that HCNTs can enhance the glass transition temperature, Tg, and thermal properties of the cured MREMA/PUA materials. The Tg of the MREMA/PUA/HCNTs nanocomposites with 5% HCNTs is 173.4 ℃, which is 64.6 ℃ higher than that of the pure resin system, and when the content of HCNTs is 7%, the 5% mass loss temperature, Td5, is enhanced approximately 38.2 ℃. The UV-cured coating film has excellent physical and chemical properties. © 2016, Chengdu University of Science and Technology. All right reserved.
