Abstract
The present invention relates to a preparation method for a UV-shielding material based on Mg—Al Layered Double Hydroxide. The material with multi-layered overlay structure is made from Mg—Al double hydroxide layers and interlayer carbonate, its molecular composition is: MgAl(OH)(CO).mHO. The inorganic layers of this material can play a physical shielding role against UV, and the metal elements dispersed on the layer as well as the interlayer anion can play a great role in the chemical absorbing. In addition, by controlling the particle size and the amount of the layers, UV light can be effectively shielded by multi-level reflection and absorption of the multi-level layered structure. Therefore, the material with multi-level chemical and physical shielding properties has a good UV barrier effect for the anti-ageing asphalt, and could significantly increase its UV resistance properties.
