The beneficial effects of the utility model are:

The thermal insulation characteristic proposed by the utility model adopts melamine foamed plastic as the thermal insulation board, and the melamine foamed plastic itself has good flame retardancy without adding a flame retardant, and a large amount of inert non-combustible gas—nitrogen will be produced after the surface is in contact with an open flame , so as to isolate oxygen and slow down the combustion speed, and at the same time, a dense coke layer is rapidly formed on the surface of the combustion body, thereby effectively preventing the combustion from developing to the deep layer; its three-dimensional grid structure with an opening rate of up to 99% effectively prevents convective heat transfer of air , has good thermal insulation properties. Compared with polyethylene, polystyrene, polyurethane and other materials, it has higher thermal stability and aging resistance, and can work in the environment of 150°C-400°C for a long time without decomposition and deformation. At the same time, melamine foam also has light Quality, sanitation and safety, environmental protection and energy saving, easy secondary processing characteristics.

The thermal insulation system proposed by the utility model utilizes the characteristics of easy processing of melamine foam plastics, and processes groove arrays on the thermal insulation board to improve the bonding strength between the thermal insulation board and the wall. .
