Insulation materials can collect excess heat, release it in a timely and stable manner, with small gradient changes, effectively reducing the amount of loss, and the room temperature can be tended to, and winter insulation can play a balancing role. In the decoration of new buildings and the renovation of old buildings, it overcomes the inherent deficiencies such as wall cracks, condensation, mildew, and peeling; and it is safe and reliable to bond with the base as a whole, with good randomness and no cavity, avoiding tearing and falling off under negative wind pressure. It effectively overcomes the problems of the side ribs after the board is spliced, the outer warping and deformation of the tiles at the positive corners, etc. The organic matter in the material reacts with the free acid in the main wall base to form a compound, which penetrates into the micropores of the main wall to form a community, ensure dry adhesion, and improve the wet adhesion value retention rate, with excellent adhesion. Raw materials such as floating beads and brucite fibers (tubular fibers) are selected, and a closed hydrophobic microporous cavity structure is formed in its structure. As a carrier of phase change materials, it can ensure the long-term practicality of phase change materials.

From the perspective of the fire resistance level of insulation materials, the insulation materials currently used in external insulation systems mainly include three categories: inorganic insulation materials, organic-inorganic composite insulation materials and organic polymer insulation materials. Organic polymer insulation materials: The most widely used energy-saving insulation system on the market is the energy-saving insulation system represented by organic polymer insulation materials, which are mainly polystyrene foam plastics and polyvinyl chloride rigid foams. They are combustible materials with a combustion performance level of E, which are dangerous to cause fire.

Inorganic insulation materials: This is a type of material that is non-combustible and has no fire safety problems, including rock wool, glass wool, expanded vitrified microsphere insulation slurry, etc. The outstanding advantage of inorganic insulation materials is that their fire resistance reaches Class A, and they are harmless to the environment and can be recycled and reused. Once applied, they are effective for a long time, and the energy-saving effect is long-lasting, which fully meets the requirements of both energy saving and environmental protection. However, other properties of inorganic insulation materials cannot fully meet the requirements of external insulation, and the dust and fine fibers they produce not only pollute the air but also easily breed bacteria, which can easily cause harm to human health. They also have disadvantages such as being afraid of water and inconvenient to construct. At present, they do not have the technical conditions for widespread application.

Organic-inorganic composite insulation materials: This material is mainly composed of glue powder polystyrene particle insulation slurry, which has low smoke emission, will not melt, and has no dripping. It is a flame-retardant material and does not have flame propagation. There is no fire safety problem itself. Although it has a certain degree of fireproof function, its thermal conductivity is relatively large. At the same time, the quality of most composite insulation slurries is unstable, and it is difficult to ensure the quality of the project. Within the thickness range of the composite insulation mortar layer allowed for use, it is difficult to meet the provisions of the limit value of the average heat transfer coefficient of the exterior wall in the building energy-saving design standard, so it has not been widely used.
