A Study on the Development of Polycarbonate corrugated sheet materials with 3-layer co-extrusion process technology for livestock barn roof

Abstract

Polycarbonate materials used for livestock barn roofing undergo degradation not only due to the factors such as temperature, humidity, and UV exposure in outdoor environments but also from gases generated in livestock settings, such as ammonia and hydrogen sulfide. Therefore, we studied the development of materials to improve weather resistance, impact resistance, and chemical resistance with various tests including DSC, FT-IR, thermal deformation, flexural strength, and impact strength, confirming the optimal content of 7 wt% (utilizing ECOZEN). In the weather resistance test, the PC-2 material exhibited a △YI 2 level, and it was observed that UV absorbers of the Benzophenone and Triazine series showed inadequate weather resistance compared to the Benzotriazole series. we expect that future development efforts will focus on creating polycarbonate-based materials with enhanced weather resistance and chemical resistance for the applications in livestock barns
