The back side of described eyeglass main body is bonded by the 3rd adhesive layer and graphite linings, and a thermal insulation layer is pasted on resistive layer surface by the second adhesive layer, and described thermal insulation layer is pasted with supporting plate and metallic support successively by the 4th adhesive layer.
The technical scheme improved further in technique scheme is as follows:
1, in such scheme, the described rectangular loop that several have opening is concentric rectangular loop.
2, in such scheme, the thickness of described first adhesive layer, the second adhesive layer is 10 μm ~ 30 μm.
3, in such scheme, the thickness of described graphite linings is 12 μm ~ 30 μm.
4, in such scheme, the thickness of described 4th adhesive layer is 30 μm ~ 60 μm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model antifogging type back mirror, its resistive layer is very reasonable in layout, very even to the heating of all parts of eyeglass, line heat source can be converted to plane heat source rapidly, effectively raise demist and go white effect and heat utilization efficiency, its structure is simple in addition, and cost of manufacture is low, is applicable to widespread production and uses; And its thermal insulation layer is pasted on resistive layer surface by the second adhesive layer, is conducive to improving heat utilization ratio, thus reduces energy consumption; Secondly, the resistive layer due to flexible base film is positioned at the surface opposing with adhesive layer, and when avoiding adhesive goods matrix metal heat resistance layer, after energising, its adhesive can be corrosive to metal surface, greatly changes its resistive performance, affects its heating effect.
