RADIOPROTECTIVE SANDWICH MATERIAL Russian patent published in 2011 - IPC B32B17/00 

FIELD: technological processes.

SUBSTANCE: invention refers to sphere of creation of radioprotective sandwich materials intended to be used as multi-purpose glasing of modern transport vehicles. Radioprotective sandwich material includes one layer of organic glass and at least two layers of polymer film. Functional electrically conductive thermal-protective coating in which layers of polymer film are made from polyethyleneterephthalate is applied to one of the films. Between them there located is additional electrically conductive layer on the basis of acrylic polymers and organic solvents with dielectric permeability ε≥60. As functional electrically conductive thermal-protective coating there used is metal dielectric coating with surface resistance of 5-30 Ohm/kV on the basis of metals and oxides or nitrides of metals chosen from the group: silver, copper, indium, titanium, stannum, aluminium.

EFFECT: invention ensures improvement of radar absorbent properties of material - reduction of the fraction of the radiation reflected from sandwich glasing in radio range at maintaining high level of resistance to impact effect, thermal-protective and optic propertires.
