Title:
ULTRAVIOLET RAY SHIELDING FILM
Document Type and Number:
Japanese Patent JP2014205811
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ultraviolet ray shielding film which can be used for plastics or objects installed in outdoor, whose raw materials are easily produced, and with which a uniform ultraviolet ray shielding effect to a surface of an object to be shielded is obtained.SOLUTION: The ultraviolet ray shielding film comprises: a base material transparent to visible light; and particles which are distributed in the base material and have a prescribed particle diameter so that ultraviolet components of solar light are scattered or absorbed. The ultraviolet ray shielding film is formed by applying a coating material, obtained by blending the particles in the base material, on the surface of an object to be shielded or sticking a film in which the particles are distributed in the base material on the surface of an object to be shielded. The particles are preferably composed of at least one of zinc oxide having particle diameters of 50-100 nm, titanium oxide having particle diameters of 60-100nm, and zirconia having particle diameters of 100-200nm. Further, it is preferable that the particles are distributed in a volume fraction 0.3 to 1.2% in the base material.
