In the metal carved plate, the so-called A grade refers to non-combustible material, in which cement is grade A, inorganic fireproof insulation board is used for wall insulation material, instead of red brick, thin wall thickness, energy saving is second to none, and indirectly It has expanded the building use area and reduced the building's own weight, which is both thermal insulation material and cold preservation material. However, at present, the popular building exterior insulation materials in the market in China are mainly organic materials. Even with the addition of flame retardants, the highest level can only reach the B1 level.

If we strictly enforce the most stringent fire protection order in history, it means that China's thermal insulation materials industry will face a situation of reshuffle or even elimination. Therefore, the call for revision of the standards for exterior insulation products in the industry has been very high for some time.

According to the conference on the development of safety and environmental protection exterior wall insulation materials industry and industry access conditions, a new generation of metal engraved board materials should be safe and environmentally friendly materials, which should meet three conditions:

1. The first is that the material production process is safe and environmentally friendly, and it does not cause direct harm to the safe and healthy environment, nor does it bury hidden dangers;

2. The second is that the material has high intrinsic safety, and it is not easy to cause safety hazards in the storage, transportation, operation, use and disposal, and it is difficult to cause secondary disasters;

3. Third, the material consumption, energy consumption, waste discharge and treatment, impact on the ecological environment and climate, and comprehensive cost of the material's life cycle are further improved than traditional materials.

The industry believes that "safety hazard does not occur" is essentially different from "no safety hazard". The statement of the Ministry of Industry and Information Technology has already made the insulation materials industry see a vitality, and all insulation material manufacturers must also invest in the new environmental protection building materials industry.
