| Summary: | 碩士 === 南台科技大學 === 化學工程與材枓工程系 === 98 === In this study, blending method and polycarbonate microemulsifying preparation / magnesium hydroxide composites, for a variety of nature, such as thermal properties, flame retardant, such as indices and dispersion characteristics. As a result of the fire-retardant material with halogen in the fatal burning will emit toxic gases, air pollution hazards to human health, so this study was to adopt environmentally friendly magnesium hydroxide as a flame retardant agent, and in order to improve between the organic and inorganic binding to silane coupling agent of magnesium hydroxide as a modification of the agent, and the use of microemulsion prepared by polycarbonate / magnesium hydroxide composites. By the experimental observation that the mixing method as the addition of magnesium hydroxide surface will result in poor dispersion and preparation in the microemulsion of polycarbonate / magnesium hydroxide composite materials have found that dispersion impact. The nature of the thermal microemulsion prepared materials to enhance the rehabilitation of the pyrolysis temperature, the thermal stability is better prepared than the mixing, the nature of the impact of the effectiveness of its fire.
