The role of polyurethane hard bubble insulation decorative integrated board

The role of the polyurethane hard bubble insulation decorative integrated board is mainly reflected in the following aspects:

Excellent thermal insulation performance: The thermal conductivity of polyurethane hard bubbles is extremely low, only 0.018-0.024W/(m·K), making it one of the lowest thermal conductivity among all thermal insulation materials at present. This means that the required insulation layer thickness is thinner when the same insulation effect is achieved, thereby reducing the thickness of the building's outer enclosure structure and increasing the indoor use area. At the same time, its closed porosity is as high as more than 90%, and it is a hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water, further ensuring the stability of thermal insulation performance.

Excellent fire resistance: After adding flame retardant, polyurethane has become a flame-retardant self-extinguishing material. Its fire resistance reaches the B1 standard and can even meet the A-level fire resistance requirements through technical improvements. During combustion, carbon deposits will be formed on the surface of the polyurethane, effectively preventing the flame from spreading and no harmful gases are generated at high temperatures, providing higher safety guarantees for the building.

Waterproof and moisture-proof: The closed-cell structure of polyurethane hard bubbles makes it have excellent waterproof performance, which can effectively prevent rainwater penetration and wall seepage, and avoid problems such as degradation of thermal insulation performance and moldy walls caused by humid environments.

Strong resistance to deformation: Polyurethane materials have stable porosity structure and are basically closed-porous structures. They not only have excellent insulation performance, but also have strong resistance to deformation, not easy to crack, and have stable and safe finish. This ensures that the sheet can maintain stable performance and appearance during long-term use.

Decorative effect: The polyurethane insulation decorative integrated board has a variety of imitation high-end stone patterns to choose from, such as thin ceramics or thin stone appearance, which overcomes the defect of monotonous color of general exterior wall paints. At the same time, its panel materials such as metal decorative panels or inorganic pre-coated decorative panels also enhance the decorativeness of the product.

Convenient and efficient construction: This sheet adopts a process of combining factory prefabrication and on-site installation, simplifying the installation process, significantly improving construction efficiency and shortening the project cycle. This highly assembled production method not only conforms to the development trend of prefabricated buildings, but also effectively reduces the quality problems of insulation system caused by improper construction.

Good weather resistance: Polyurethane has good chemical stability, excellent corrosion resistance, and can resist harsh environments such as acid rain. At the same time, its anti-pollution and stain resistance are also good, and it is not easy to reverse alkali, ensuring the long-term beauty and service life of the board.

Energy-saving and environmentally friendly: Polyurethane hard foam is fluorine-free foaming, and does not use harmful substances prohibited or restricted by the state, and is green and environmentally friendly. At the same time, its excellent thermal insulation performance can reduce heating and cooling energy consumption and achieve the goal of energy conservation and emission reduction.

Long service life: The polyurethane insulation decorative integrated board has a long service life, which can be achieved without damage under the influence of external factors such as dryness, humidity or electrochemical corrosion under normal service life.

Sound insulation and noise reduction: The core material in the middle of the board is a thermal insulation layer composed of high-density polyurethane foam, and its interior is an independent closed bubble structure, which has good sound insulation effect. Suitable for apartments, hospitals, schools and other buildings near noise areas.
