Heat Ray Shielding Glass for Vehicle and Process for Producing the Same
摘要:
[Problems] To develop a heat ray shielding glass usable as a vehicle glass having up-and-down function, the heat ray shielding glass having a film hardness and generating no abnormal noise by friction due to up-and-down movement.[Means for Solving Problems] A heat ray shielding glass for vehicle, including a glass substrate and a heat ray shielding film formed on at least one surface of the glass substrate, in which the heat ray shielding film includes: conductive oxide ultrafine particles dispersed in the film; and a silica binder for binding the ultrafine particles to each other, the silica binder including solid contents produced by hydrolysis and polycondensation of tetraalkoxysilane and trialkoxysilane. In the heat ray shielding film, a ratio between the solid content made from the tetraalkoxysilane and the solid content made from the trialkoxysilane is within a range of from 55:45 to 85:15 on a weight percentage basis, and a ratio between the conductive oxide ultrafine particles and the silica binder is within a range of from 35:65 to 70:30 on a weight percentage basis.
