Abstract:
A floor projection screen to be installed in front of department stores, shops, shopping malls, and a method for manufacturing the same are disclosed. The floor projection screen is formed by overlapping a hard screen material, which is obtained by mixing white cement with a light diffuser such as glass beads, silica, etc. having a particle of 400 to 800 mesh, or by mixing plastic resin with white cement, calcium material, pigments, etc., and a soft material such as urethane, rubber, or non-woven fabrics, thereby achieving vivid imaging, an anti-skid function, and durability for friction. The floor projection screen is manufactured by stacking a screen material on a surface of a tape-shaped soft material and rolling and hardening the screen material to complete a screen having a centric ring pattern, or by stacking a screen material on a surface of a tape-shaped soft material, repeating the stacking step until a desired size of the screen is obtained, and hardening the resulting stack to achieve a screen surface having a particle size of 40 to 800 mesh.
