Embodiment 1

[0036] Prepare a kind of far-infrared energy-saving coating, contain the component of following weight:

[0037] Black silicon carbide 35kg, copper oxide 20kg, alumina 15kg, quartz sand 5kg, silica powder 20kg, nano silicon carbide 0.05kg, nano silicon dioxide 0.05kg.

[0038] Among the above components, black silicon carbide, metal oxide, quartz sand and silica powder are all micropowders with a fineness between 400 mesh and 600 mesh. After the above components are uniformly mixed under normal temperature and pressure, they are dissolved in silica sol of the same weight to obtain the far-infrared energy-saving coating of the present invention.

Embodiment 2

[0040] Prepare a kind of far-infrared energy-saving coating, contain the component of following weight:

[0041] Green silicon carbide 40kg, copper oxide 30kg, alumina 20kg, quartz sand 10kg, silica powder 10kg, nano silicon carbide 0.1kg, nano silicon dioxide 0.1kg.

[0042] Among the above components, green silicon carbide, metal oxide, quartz sand and silica powder are all micropowders with a fineness between 400 mesh and 600 mesh. After mixing the above components uniformly at normal temperature and pressure, dissolve in silica sol twice the weight of the mixture to obtain the far-infrared energy-saving coating of the present invention.

Embodiment 3

[0044] Prepare a kind of far-infrared energy-saving coating, contain the component of following weight:

[0045] Black silicon carbide 35kg, green silicon carbide 35kg, copper oxide 25kg, iron oxide 25kg, quartz sand 10kg, silica powder 20kg, nanometer silicon carbide 0.1kg.

[0046] Among the above components, black silicon carbide, green silicon carbide, metal oxide, quartz sand and silica powder are all micropowders with a fineness between 400 mesh and 600 mesh. After mixing the above components uniformly at normal temperature and pressure, dissolve in silica sol 1.5 times the weight of the mixture to obtain the far-infrared energy-saving coating of the present invention.
