Title:
SOLAR HEAT HIGH-REFLECTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/018682
Kind Code:
A1
Abstract:
Provided is a structure for paving roads and the like and forming the walls, roofs, rooftops, and the like of buildings, the structure achieving an increase in the amount of retroreflection of sunlight and a reduction in the amount of specular reflection and diffuse reflection of sunlight even if special objects such as glass beads are not arranged on the surface of a paint layer, and, as a result, enabling suppression of a heat island phenomenon. A solar heat high-reflection structure (1) has a surface that is subjected to roughening processing so that a retroreflectance of 1.0 or more (here, the retroreflectance is a value represented by "S/R" where "R" is the reflected light intensity within the range of 30°±10° and "S" is the reflected light intensity within the range of 150°±10° when light with a wavelength of 900 nm is incident at an angle of 150°) is exhibited. The surface is formed by placing a paint layer (4) produced from a solar heat high-reflection paint on a surface forming layer (3) having roughness (5).
