BUILDING MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

The invention relates to a highly durable building material and a method for producing the same. The building material prevents the substrate or an intermediate resin layer from being decomposed by 5 photoradicals that may be generated from zinc oxide. Provided is a building material in which an ultraviolet protection layer containing zinc oxide particles and silica particles is formed directly on the surface of a substrate or indirectly with an intermediate resin layer interposed between the substrate and the ultraviolet protection layer. The silica particles are fixed to the 10 substrate or the intermediate resin layer.
