Abstract
The geography, atmosphere, rock mineral, and chemical composition of the Dazu Rock Inscriptions are described. The results suggest that the main type of weathering of the Dazu Rock Inscriptions is chemical. A new product, an acrylate-organic silicon nucleus/shell IPN Emulsion, is developed as an ideal protective material of the inscriptions because of its low contamination properties and low cost. It has the merits of organic silicon coating and polyacrylate coating, overcomes the "protective" damage made by the poor wet air permeability (24.0%) of polyacrylate coating, and a quick decrease in adhesive force of organic silicon coating.
