Green and environmental-friendly heat insulation board

Abstract

The invention discloses a green and environmental-friendly heat insulation board which comprises an intermediate support material with a honeycomb structure. Two sides of the intermediate support material are wrapped by high gas barrier material layers; low-radiation-coefficient surfaces are arranged on the inner side surfaces of the high gas barrier material layers; air, argon, carbon dioxide ormixtures thereof are filled in honeycomb holes of the intermediate support material, or the honeycomb holes of the intermediate support material are vacuumized; phonon eutectics are coated on the low-radiation-coefficient surfaces and the surface of the intermediate support material or mixed with the intermediate support material; and the high gas barrier material layers and the intermediate support material are glued by adopting glues. According to the green and environmental-friendly heat insulation board provided by the invention, through adopting the reasonable structure for matching withthe phonon eutectics, the transfer of a heat flow can be reduced, and the green and environmental-friendly heat insulation board has a low heat conductivity coefficient, light weight and a good flame-retarding effect, can be cut into any size so as to meet the installation requirement, can be folded into multiple layers for use so as to meet the requirements on the installation thickness and a heat resistance value, uses recyclable materials, is simple in production process and use process and non-pollution, and belongs to green and environment protection.

Description

technical field [0001] The invention relates to a green environmental protection material, in particular to a green environmental protection thermal insulation board used for thermal insulation of walls and other objects. Background technique [0002] Heat transfer occurs by three mechanisms: conduction, convection, and radiation. Heat conduction is the transfer of kinetic energy between molecules of matter. Convection is the transfer of heat by molecules of matter moving from one place to another in space. Thermal radiation is the heat transfer in the space between two objects by electromagnetic waves. [0003] The development of thermal insulation materials is to try to reduce heat conduction, heat convection and heat radiation. Many insulation materials have been around since the 1950s, but widespread use did not begin until the oil crisis of the 1970s. Due to the oil crisis, coupled with improved living conditions, the need to insulate buildings, prevent heat loss an...

AI Technical Summary

Problems solved by technology

These problems include: (1) It is difficult to maintain a vacuum long enough to make it useful as a commonly used thermal insulation material

(2) The materials used for outer wrapping layer, core material, getter and sealing are more expensive

(3) Vacuum board VIP cannot be cut, because the cutting air leaks and the vacuum degree drops

(5) Most of the vacuum panel VIP core materials are commonly used materials for thermal insulation materials, which have environmental protection problems and affect the ecological environment and sustainable development.

These problems limit the practical application of vacuum panel VIP

[0019] Commonly used external wall thermal insulation materials are not green and environmentally friendly, affecting the ecological environment and sustainable development, and there are fire hazards

Foreign countries began to pay high attention to the environmental protection problems of commonly used thermal insulation materials more than 20 years ago, and started research work in this area, but in addition to improving thermal insulation performance to reduce material consumption and recycling In addition to the great progress in technology, the progress of alternative new materials is slow
