Description

Technical Field

[0001] The utility model relates to the technical field of assembled wall panels, in particular to an assembled thermal insulation wall panel combining wood and an electric heating film. Background Art

[0002] Compared with high-energy-consuming building materials such as cement and concrete, wood can be called a standard low-carbon material because of its green, pollution-free, and naturally renewable properties. Wood building structures have mature practices and a high degree of industrialization, and are widely used in low-rise residential buildings and public buildings.

[0003] The electric heating film is made of a special conductive ink and a metal current-carrying strip that is processed and hot-pressed between insulating polyester films. The electric heating film is divided into two categories: high-temperature and low-temperature. The high-temperature electric heating film is generally used for electronic appliances, and the low-temperature electric heating film is usually used for building heating. The low-temperature electric heating film generates heat after being powered on, and sends the heat into the space in the form of radiation, so that the human body and objects are warmed first. Its comprehensive effect is better than the traditional convection heating method. Since the electric heating film is a pure resistance circuit, its electric heat conversion efficiency is as high as 98%. The low-temperature radiation electric heating film heating system is a low-carbon heating high-tech product.

[0004] Combining two low-carbon products, wood and electric heating film, into assembled insulation wall panels has a wide range of use scenarios in building materials. In low-rise buildings, such as resorts, farms, and ecological parks, assembled wall panels combined with wood and electric heating film integrate the building with the environment, making the building planning more reasonable and the form more diverse. In Inner Mongolia and Xinjiang, where the population is sparse, the land is vast, the population is scattered, and the light and wind energy resources are rich, the assembled wall panels combined with wood and electric heating film can be used with household wind / solar power generation equipment to generate electricity for heating on site, which can cleanly and efficiently meet the needs of local residents for heating, warmth preservation, and easy disassembly and migration. Summary of the invention

[0005] The utility model aims to provide an assembled thermal insulation wall panel combining wood and low-temperature electric heating film, which is required to have a high level of overall structural strength, thermal insulation and heating effects, and is easy to install, disassemble and transport.

[0009] Furthermore, the reflective film layer 3 is an aluminum-plated reflective film, which is protected by two layers of PET film, and can reflect the radiated heat of the electric heating film heating element to the inner layer, effectively reducing the amount of heat loss to the outside, and improving the heating energy-saving efficiency.

[0010] Furthermore, the electric heating film layer 4 is a low-temperature electric heating film, and its main function in the novel wallboard is to provide electric heating and heating function. The film is safe, energy-saving, moisture-resistant and anti-aging, and has a service life of up to 50 years;

[0011] Furthermore, the covering protective layer 5 is a PE material protective film, which has good performance in terms of moisture resistance, heat insulation, flame retardancy, etc., and can meet the design requirements of the utility model. In addition, the PE film is not easy to age and has a long service life, which can fully protect the use of the electric heating film.

[0012] Furthermore, the cement mortar heat storage layer 6 mainly functions to store and distribute heat, and also has the function of enhancing the firmness of the wall and providing attachment for the outer decorative panel;

[0013] Furthermore, the equipotential network layer 7 is made of galvanized steel wire mesh, which is a protective measure to ensure the safety of electricity use and can effectively prevent leakage and electric shock. This layer of galvanized steel wire mesh can be fully buried in the cement mortar heat storage layer;

[0014] Furthermore, the wooden board decorative layer 8 is the innermost decorative layer of the wall panel, and its main function is to beautify the appearance, and it also has the function of strengthening the wall.
