PROCEDURE FOR APPLICATION OF HEAT SHIELDING COATING ON POLYMER MATERIAL Russian patent published in 2011 - IPC C23C14/06 C23C14/35 C03C17/36 B32B18/00 

FIELD: metallurgy.

SUBSTANCE: procedure consists in successive application of first dioxide layer on transparent polymer substratum by vacuum magnetron sputtering. The layer is sputtered to thickness meeting the requirement: d_1T=(25-40)+275×m/n_T (nm), where m=0 or 1, d_1T is thickness of the first dielectric layer of titanium dioxide, n_t is a refractive index of titanium dioxide, the layer of metal made out of silver, a barrier layer made out of aluminium nitride and having thickness as high, as 3 nm, and the second dielectric layer made out of titanium dioxide to thickness meeting condition: d_bXn_b+d_2T×n_T=(25-40)×n_T+275×k (nm), where d_b is thickness of a barrier layer of aluminium nitride, nb is a refractive index of aluminium nitride, d_2T is thickness of the second dielectric layer of titanium dioxide, k=0 or 1.

EFFECT: raised coefficient of attenuation of heat solar radiation at maintaining high transmission efficiency of visible light.
