Title:
HIGH VISIBLE RAY TRANSMISSIVE HEAT RAY REFLECTION GLASS
Document Type and Number:
Japanese Patent JP3261689
Kind Code:
B2
Abstract:
PURPOSE: To provide a high visible ray transmissive heat ray reflection glass free from defects such as the decrease of perspective safety, ill effect of reflected light, low weather resistance by forming a specific oxide film on a glass substrate high in visible ray transmissivity.
CONSTITUTION: The coating film composed of the oxide is formed on the glass substrate over 86% in visible ray transmissivity for C light source in 5mm plate thickness and <85% in solar radiation transmissivity to have ≥56% visible ray transmissivity for C light source and ≤67% solar radiation transmissivity. That is, the oxide film composed of a mixture of tin oxide with antimony oxide, a mixture of tin oxide and antimony oxide with fluorine or a mixture of tin oxide and antimony oxide with titanium is formed on the glass substrate high in visible ray transmissivity. The high visible ray transmissive heat ray reflection glass secures high visible ray transmissivity by using the glass substrate and exhibits heat ray reflectivity without disturbing the visible ray transmitting property of substrate by forming the oxide film on the substrate.
