||With the goal for the application of attapulgite in polymer composites and luminous materials, this dissertation optimized the purification and modification technologies of the attapulgite raw material. Then, the natural rubber/attapulgite and nitrile butadiene rubber/attapulgite/hydrotalcite nanocomposites were prepared. Additionally, yellow phosphor was synthesized by using the attapulgite as the matrix materials. It provided a new way for the application of attapulgite in white LED materials. Furthermore, the preparation technology of the nitrile butadiene rubber/attapulgite nanocomposite was improved based on the existing research work in our group, while perfected the nanocomposite from small to pilot a larger version of the experiments. It laid a foundation for the future industrialized production and commercialization application of the NBR/attapulgite nanocomposite.
