| 摘要: | 合成樹脂產業種類繁多，應用範圍也相當廣泛，隨著產業的變遷、市場的消長、技術的擴散，以及綠色環保競爭力的壓力下，過去傳統的溶劑型PU操作需要使用大量溶劑，且有機溶劑易燃易爆、易揮發，硬化過程中又會大量釋出溶劑，造成空氣汙染及生態環境汙染，影響公共安全，因此溶劑型PU發展受到限制，逐漸被環保型水性PU取代。本實驗使用的環保型水性PU是對環境無汙染的材質，但是水性PU的性質有較低的分子量、耐水解性和耐熱性，為了補強環保型水性PU性質上的不足，因此加入奈米氧化鋁粉末，利用其粉末高強度、高硬度、耐高溫、耐燃性佳和良好抗腐蝕性能的本身性質，製作出水性PU/奈米氧化鋁之奈米複合材料，可以有效地強化水性PU之機械性質及熱性質，使得水性PU的應用更廣泛。
本研究旨在製備水性PU/奈米氧化鋁之複合材料研究，並檢測其物理性質、熱性質、機械性質與光學性質。本實驗使用氨基乙基甲基丙烯酸酯鹽酸鹽 (Aminoethyl methacrylate hydrochloride , AEMA)接枝於奈米氧化鋁表面進行改質。用以水性PU添加Al2O3和m-Al2O3奈米複合材料的製備與不同的成份克數(每100克的樹脂所含該之成份克數)。
探討不同成份克數的Al2O3和m-Al2O3對水性PU奈米複合材料的形態學(FT-IR、SEM及XRD)、物理性質(密度、空孔率)、機械性質(硬度、耐磨耗指數、抗張強度及耐衝擊強度)、熱性質(TGA、MI、DSC及VST)及光學性質(透光率)之性能和影響的差異程度。
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). |
