碩士 === 中國文化大學 === 化學工程與材料工程學系奈米材料碩士班 === 105 === A wide range of synthetic resin industry, the scope of application is also quite extensive, with the industry changes, market growth and decline, the proliferation of technology, and green environmental competitiveness under the pressure of the traditional solvent-based PU operation requires the use of a large number of solvents, and organic solvents flammable and explosive, volatile, hardening process will be a lot of solvent release, resulting in air pollution and ecological pollution, affecting public safety, so the development of solvent-based PU is limited, gradually replaced by environmentally friendly water-based PU. The environment-friendly water-based PU used in this experiment is a non-polluting material for the environment, but the nature of the waterborne PU has a low molecular weight, hydrolysis resistance and heat resistance. In order to improve the nature of the environmentally friendly waterborne PU, Aluminum powder, the use of its high-strength powder, high hardness, high temperature, good flame resistance and good corrosion resistance of the nature of its own, to produce water-based PU / nano-alumina nano-composite materials, can effectively strengthen the water-based PU machinery Nature and thermal properties, making the application of water-based PU more extensive. This project is to research the waterborne PU/ nano-Aluminium oxide composites and determine properties about physical, mechanical properties, electrical properties, optical properties and dynamic mechanical properties. In this study, using Aminoethyl methacrylate hydrochloride (AEMA) was grafted onto the surface of nano-Aluminium for modification. For the waterborne PU Add prepared Al2O3 and m-Al2O3 Nanocomposites with a different number of grams of composition (per 100 grams of resin contained in the composition of the number of grams). Explore the different components of the number of grams of Al2O3 and m-Al2O3 nanometer morphology of waterborne PU nanocomposites (FT-IR, SEM and XRD), physical properties (density, porosity), mechanical properties (abrasion index, tensile strength and impact strength), thermal properties (TGA, MI, DSC and VST), electrical properties (dielectric constant) and the optical properties (transmittance).
