METHOD OF OBTAINING STRENGTHENING HEAT-REFLECTING CLARIFYING COATING FOR TRANSPARENT PLASTIC PRODUCTS Russian patent published in 2015 - IPC C23C14/08 C23C14/20 C23C14/35 

FIELD: chemistry.

SUBSTANCE: method of obtaining strengthening heat-reflecting clarifying coating for transparent plastic product includes formation of sublayer, application of heat-reflecting layer of tin oxide SnO₂ and application of clarifying layer of silicon dioxide SiO₂. Said layers are applied by magnetron sputtering in argon and oxygen medium. As sublayer applied is strengthening adhesion layer of silicon oxide SiO_x, at 1.5≤x<2.0, with thickness (2.7-3.3)·λ₀/4, where λ₀=550 nm, heat-reflecting layer of tin oxide SnO₂ is applied with thickness (3.6-4.4)·λ₀/4 and clarifying layer of silicon dioxide SiO₂ - with thickness (0.9-1.1)·λ₀/4.

EFFECT: increased mechanical abrasion resistance of strengthening heat-reflecting clarifying coating.
