Abstract A heat-conducting mat for absorbing microwave and electromagnetic wave energy comprising: a basic metal material selected from the group including bronze, silver and soft iron, the basic metal material being pressed to form a piece of mat and capable to be rolled up; and a heat-conducting film being coated on the basic metal material; wherein the heat-conducting film comprising a heat-collecting coat comprising a first paste-like mixture of iron oxide powder, ruthenium, glass powder and medium; an electromagnetic wave energy absorbing coat comprising a second paste-like mixture of creaming gold, silver powder and the medium, the electromagnetic wave energy absorbing being printed and coated on the heat-collecting coat; and a protecting coat comprising a third paste-like mixture of iron oxide powder and glass powder, the protecting coat being coated on the electromagnetic wave energy absorbing coat so as to protect the basic metal material from generating static electricity or sparks. So that the piece of mat can be used for a microwave oven and an electromagnetic wave oven.
A heat-conducting mat for absorbing microwave and electromagnetic wave energy comprising: a basic metal material selected from the group including bronze, silver and soft iron, said basic metal material being pressed to form a piece of mat having a thickness of 0.5 mm and capable to be rolled up; and a heat-conducting film being coated on said basic metal material; wherein said heat-conducting film comprising a heat-collecting coat comprising a first paste-like mixture of about 4% iron oxide powder, about 20% ruthenium, about 24% glass powder and about 52% medium, wherein said medium mainly including 53% aromatic solvent and 30% synthetic material; said heat-collecting coat having a thickness of 0.03 mm and a density of 0.005 g/cm 2 ; an electromagnetic wave energy absorbing coat comprising a second paste-like mixture of about 8% creaming gold, silver powder and about 55% said medium, said electromagnetic wave energy absorbing coat having a thickness of 0.09 mm and a density of 0.02 g/cm 2 and being printed and coated on said heat-collecting coat; and a protecting coat comprising a third paste-like mixture of about 10% iron oxide powder and about 90% glass powder, said protecting coat being coated on said electromagnetic wave energy absorbing coat so as to protect said basic metal material from generating static electricity or sparks.
