| Popis: | 97 In this research, we add different types of anti-static agents to PVC/TPU polymer composite for discussing their anti-static and physical properties. In addition, this research shows the chemical mechanism between matrix and anti-static agents, and how much they affect in the composites. Now, the government pays more attentions on environmental protection, so how to reduce the hazardous components within materials is the goal that every industry has to achieve. However, while developing new materials, it’s also necessary to consider its additional functions. Although PVC possesses great processing ability in different ways, its applications are defined due to environmental pollution factors. Thus, in current industries, it must blend other polymers to reduce its chlorine contents to avoid environmental pollution. We prepare the standard samples of the innovative materials by adding different anti-static agents and other additives such as stability agents and plasticizer through two-roll milling. Then, we use different analysis apparatus to compare their properties and interactions between the composites and anti-static agents. Ultimately, we will get the brand-new PVC/TPU composites that meet the practical applications and prevent the environment from polluting. As the result of the research, adding the Esters into the PVC/TPU has the best efficiency of electric conduction in these tested anti-static agents, and the tested value of electric conduction drops to 3.22 × 108 Ω/sq from 2.87 × 1012 Ω/sq. Moreover, the Esters completes the route of electric conduction cause of the great compatibility and separation. Furthermore, we may learn it has the fabulous thermal stability from the TGA and DSC analysis, therefore, there’re rarely cracking and decomposing issues in processing operation. |
