Detailed Description
A compound wall paper that generates heat, its concrete preparation mode does, decorate the wall paper skin, generate heat the middle level and arrange in proper order with the heat preservation inlayer and place. The decorative outer layer and the heat-insulating inner layer are connected through the through holes of the heating middle layer to form the heating wall cloth. The connection may be any connection means. In consideration of the strength and reliability of the connection, one or more of metal nail connection, plastic nail connection, polymer adhesive connection, textile thread connection, connection formed by interweaving fibers carried by the decorative outer layer and/or the thermal insulation inner layer are preferable.
The wall cloth decorative outer layer mainly plays a role in decoration and protection. The heating middle layer drives the whole wall cloth to generate heat through the heating function of the heating middle layer, so that the whole wall surface has the heating function. The heat preservation inner layer is used for being combined with the wall surface and reducing the heat conduction of the heating layer to the wall body.
The outer wall cloth decoration layer and the inner heat insulation layer are made of fabric materials, and the middle heating layer is a heating film which is completely sealed and packaged.
The outer wall cloth decoration layer and the inner heat insulation layer are made of traditional fabric materials, and the wall cloth is guaranteed to have no obvious difference from the traditional process in hand feeling and installation. The heating middle layer is a heating film packaged in a plastic package, and mainly plays a role in heating, insulating and guaranteeing safety.
Wherein, the heating middle layer comprises a heating area and a non-heating area; and the non-heating area comprises a through hole.
The through hole is used for enabling the wall cloth decoration outer layer to be in full contact with the heat preservation inner layer, and therefore the effect of stable fixation is achieved. If be a whole heating film can make wall paper decorate skin and wall and keep apart, be difficult to carry out stable fixed, have the risk of becoming flexible, peeling off, dropping in long-term use.
Wherein the total area of the non-heating area is less than 20% of the total area of the heating film.
The proportion of the total area of the non-heating area to the total area of the heating film should be as small as possible to ensure that the composite heating wall cloth can uniformly heat. Therefore, the ratio is preferably 10% or less, and more preferably 5% or less
The area between the through hole and the heating area is an insulating packaging area, and the width of the insulating packaging area is 1-10 mm.
The through hole is positioned in the non-heating area, and an enough insulation distance is required between the through hole and the heating area to ensure safety. Poor sealing or damage easily occurs when the insulation width is too narrow; too wide can result in too large a non-heat generating area, resulting in uneven heating. Therefore, the width is preferably 2 to 5 mm.
Wherein the heat generating middle layer comprises an insulating packaging layer, a heat generating composition and an internal circuit. The heat-generating composition is connected to an internal circuit and sandwiched by an insulating encapsulating layer.
The insulating packaging material may be any insulating material. In view of the flexibility and safety of the heat-generating wall cloth of the present invention, the heat-generating wall cloth is preferably a high molecular polymer film, and is further preferably one or more of a polyethylene film, a polyester film, a polyurethane film, a polyvinyl chloride film, and a polyimide film.

Wherein the metal filaments may also be referred to as metal fibers and/or metal strips. The metal is preferably one or more of aluminum, copper, iron, steel, silver, gold, and platinum.
Among them, the heat-generating composition preferably contains a graphene material, and the content of the graphene material in the heat-generating composition is 5 to 80%.
Since the graphene has high heating and far infrared generation functions, the graphene cannot have the functions of quick heating and radiation heat transfer when the addition amount is too small; the addition of too much causes non-uniformity in film formation of the heat-generating composition and generation of defects. Therefore, the content thereof in the heat-generating composition is preferably 10 to 60%, and more preferably 20% to 40%.
Wherein the heat-generating composition has a PTC function. The heating wall cloth has the advantages that when the temperature controller is abnormal, the heating wall cloth stops heating at a certain safe temperature, and accordingly safety is improved. The PTC function is referred to as a positive temperature coefficient. That is, the resistance of the heat-generating composition itself increases with an increase in temperature, thereby achieving the purpose that the heat-generating power thereof decreases with an increase in temperature.
And a metal reflecting layer is arranged between the heating middle layer and the heat preservation inner side and is connected with a zero line or a grounding line.
The metal reflecting layer can be made of any metal reflecting layer material in the prior art. Preferably a copper foil or an aluminum foil.
The beneficial effects of the metal reflecting layer are mainly embodied in two aspects: on the one hand, because graphite alkene can produce far infrared radiation in the use, the metal reflecting layer can reflect this part of heat back indoor, increases the electric energy availability factor. On the other hand, a trace amount of leakage current may be generated due to an electromagnetic induction phenomenon in the use process, the leakage current may cause tripping or other potential safety hazards of a protection power supply, and the metal foil of the reflection layer may conduct the current to a zero line or a ground line, so that the use safety is guaranteed.

And connecting an external circuit with a low-voltage power supply to obtain the heating wall surface. The 220V voltage used in China is very dangerous. Therefore, the low voltage power supply is preferably not higher than 60V. More preferably not higher than 36V.
In order to control the temperature of the heating wall surface, a temperature control device is also arranged on one side of the wall surface close to the external power supply.
The temperature control device is mainly used for adjusting the temperature of the wall cloth, and the main principle is that the temperature of the outer layer of the wall cloth decoration is detected through a temperature detector in contact with the wall cloth, the temperature is compared with the set temperature, and the on-off of a power supply is controlled according to the difference, so that the purpose of controlling the temperature is achieved. To obtain more precise temperature control, PID control is preferable. For a more convenient control experience, a wireless remote control is preferred.
