Exemplary implementation of the utility model

The presented panels consist of several layers, each of which is made of a different material. The type and thickness of the layers are determined by the specific application of the panels, using metal foams of composite materials / mixture of aluminum alloy and solid particles /, as well as foams with a gradient structure / foam materials with different porosity in different areas. /, the composition of which is selected depending on the desired qualities of the final product obtained.

According to the attached figure 1, the multilayer thermal and sound insulation panel comprises three layers connected in series, wherein layer 1 is a hard, dense layer of terracotta, ceramic or stone. Layer 2 is a hard layer of closed-pore aluminum foam. Layer 3 is a soft, plastic layer of refractory fibers obtained from natural raw materials - sand and kaolin. This layer has an effective coefficient of thermal conductivity in the range λ = 0.029 - 0.039 W / m K. Such material is non-flammable and serves both for heat and noise insulation and as a barrier for the spread of fires.

The proposed multilayer panel for thermal and sound insulation, insulation from moisture, high-energy air jets and electromagnetic radiation can be used for different purposes in different areas of industry. The thickness of the three layers of the panel is generally in the ratio as follows: Δ1: Δ2: Δ3 = 5: 15: 7. This ratio varies depending on the specific application.

For example, when using the multilayer panel for construction of walls of permanent or movable dwellings, the parameters are the following: thickness of the first layer Δ1 = 6 шш, thickness of the second layer Δ2 = 15 шш and thickness of the third layer Δ3 = 10 шш. Total panel thickness Δ = Δ1 + Δ2 + Δ3 = 31 w. In terms of weight, the part of each layer in the case under consideration is wl = 49%, w2 = 37% and w3 = 14%, respectively.

The proposed multilayer insulation panel is manufactured from known raw materials, using innovative technology and complies with the requirements of environmental protection, resulting in a new product with new qualities and areas of application.
