Technical Field

The utility model relates to the technical field of decorative paintings, in particular to a heating decorative painting.

Background

At present, the decoration picture that generates heat is mostly with the brilliant electric plate of carbon and graphite alkene as the source that generates heat, but graphite alkene generates heat, and the brilliant electric plate of carbon self generates heat and can only reach the low temperature of 180 ~ 200 degrees, and the temperature is lower to the decoration picture of heating, can not reach the heating effect well.

The heating film layer formed by the graphene and carbon crystal electric heating plates is unstable, easy to damage by collision and easy to oxidize, and has high attenuation degree and the like. The greatest defects of the heating layer and the picture layer of the graphene heating glass decorative picture and the carbon crystal electric heating plate decorative picture are that the picture layer is not afraid of water and moisture, the picture layer not only fades and can bubble after being placed for several years, and the phenomenon of hollow patterns occurs, and the heating layer is easily oxidized and quickly attenuates.

In addition, the decorative picture is printed by a UV printer, the temperature resistance limit of ink of the UV flatbed printer is between 150 ℃ and 240 ℃, and if the temperature is exceeded, the ink cannot be attached to the surface of an object, so that the pattern is peeled off and deformed. Also, the inks deteriorate when exposed to acids and alkalis, which in turn leads to distortion of the decorative picture pattern. And the printed picture is not wear-resistant and is easy to bump and grind. The graphite alkene glass decoration of uv printing is drawn, and the brilliant electric plate decoration of carbon is drawn fixed production only, and it generates heat the rete and can't tailor, can destroy the rete that generates heat, and the picture layer also can be scraped the flower, damages. Subsequent processing is difficult. The uv printing is performed by using low-temperature ink, and is only printed on the surface of the glass through drying at 70-100 ℃ in the manufacturing process. When the graphene heating glass decoration picture and the carbon crystal electric heating plate decoration picture are heated to more than 100 ℃, the picture layer is partially dissolved and emits irritant gas harmful to a human body.

The greatest defects of the heating layer and the picture layer of the graphene heating glass decorative picture and the carbon crystal electric heating plate decorative picture are that the picture layer is afraid of water and moisture, the picture layer not only fades and can also bubble after being placed for several years, and the phenomenon of hollow patterns occurs, and the heating layer is extremely easy to oxidize and quickly attenuate.

The transparent N-type semiconductor nano electrothermal film is a new generation of heating material. The heating mode of the heating wire is different from that of the traditional metal resistance wire. It has excellent physical and chemical properties of corrosion resistance, oxidation resistance, temperature shock resistance, insulation, flame retardance, moisture resistance, high hardness, no toxicity, no harmful radiation, no discharge of harmful substances and the like. It has zero inductive reactance, pure resistance heating and power factor of 1. And the surface-shaped heating breaks through the traditional resistance wire in a linear heating form, the heat transfer effect is good, and the electric heat conversion efficiency is high: 80% -97%, has better energy-saving advantage. The service life is long, the material is not easy to decay, and the accelerated life passes 5000 hours of test. The formula adopted by the electrothermal film liquid in the prior art ensures that the prepared electrothermal film has unstable effect and higher attenuation degree, and the film coating process is immature and cannot reach uniformity, so that the film layer is easily damaged under the condition of high-temperature dry burning.
