Market promotion value of exterior wall thermal insulation exterior decoration coating system

in view of the characteristics and existing problems of building exterior finishes, China's building exterior decoration material market has undergone great changes in recent years, from commonly used coatings and ceramic tile finishes to new elastic Dutch art paint, color decorative mortar, flexible face brick, porcelain stone paint and real stone paint. Among them, elastic Heyi paint has new thinking functions such as hydrophobic self-cleaning, elastic repair, breathing and ventilation; Color decorative mortar has the characteristics of natural color texture, low comprehensive cost, never fade and convenient construction; The flexible facing brick has the characteristics of light weight, thin body, good economy, strong weather resistance, good waterproof and air permeability, and never fade

according to the investigation of the exterior wall external insulation and exterior decoration coating system popularized and applied in the market, several types of products commonly used at present have different disadvantages in recent years. Although ordinary acrylic exterior wall paint products have beautiful colors, plump film, good color retention, good covering power and adhesion, and moderate price, these products belong to hydrophilic coatings, do not have hydrophobic and self-cleaning ability, and cannot solve the cracks in the wall and the water seepage of the wall caused by them. Although the exterior wall elastic paint has good elasticity, strong resistance to base deformation, good crack resistance effect, can cover subtle cracks, plump paint film, and good color retention, but this kind of product has low paint film hardness, poor anti fouling function, and is easy to be polluted. Although Heyi paint has the advantages of lotus leaf hydrophobic effect, strong self-cleaning ability, good one-way permeability, strong environmental adaptability, good aging resistance, etc., this kind of products do not have the ability to make up for cracks. In contrast, the new silicone acrylic resin hydrophobic coating for exterior wall external insulation with acid rain resistance and pollution rain resistance, elastic Heyi paint, integrates the comprehensive functions of the above categories of products, filling the gap between hydrophobic self-cleaning function and high elasticity of domestic paint products. This kind of product is painted on the outside of the insulation layer like a lotus leaf. In case of rain, it can form water droplets and automatically roll down. It can not only be cleaned by domestic diaphragm enterprises mainly using dry diaphragm, but also resist erosion and cracking, and play a good role in protecting the insulation system. In addition, this level of material has certain characteristics, such as hydrophobicity, stain resistance, elastic crack resistance, acid rain resistance, pollution rain resistance and so on. It is a low VOC water-based green environmental protection product, Good recoating function, convenient for construction

cracks in the external insulation system of exterior walls are a common and unavoidable problem. Once cracks appear on the surface of the external wall external insulation system, it will not only affect the appearance, but also make water enter the wall. The length of the external wall external insulation system is often unfavorable or even fatal. If the crack expands further, it will threaten the safety of the main structure of the building. Therefore, the exterior coating used in the system not only needs to have the ability to cover the crack, but also can play the role of compensation for the crack. Because the microstructure of the film surface has hydrophobic function, the elastic Heyi paint popularized in the market can improve the moisture-proof and moisture-proof ability of the material, so as to ensure that the material has a low thermal conductivity. In particular, the application of silicone acrylic resin hydrophobic high elastic coating in the external wall external insulation system can fully display the function of silicone acrylic resin hydrophobic high elastic coating and show the advantages of the external wall external insulation system incisively and vividly

experts said that elastic Heyi paint products meet the current direction of paint development, meet the needs of paint product upgrading and the pursuit of high-performance and multi-function, especially suitable for the application of external wall external insulation system. As a building latex coating product with high weather resistance, high stain resistance, high self-cleaning, high color retention and low pollution, elastic Heyi paint effectively makes up for the cracks in the external wall insulation system, improves the efficiency of building insulation and energy conservation, saves energy, and has good social benefits. According to relevant information, in order to welcome the 2008 Olympic Games, Beijing has repainted the facades of about 9600 buildings around the main streets to ensure the appearance of the city. If elastic Heyi paint is used, it can not only reduce the number of "face washing" of buildings, but also save a lot of resources and related costs. Secondly, it is more economical to use elastic Heyi paint external finish than ceramic tile finish. The one-time investment in using ceramic tile veneer is large, and the labor and auxiliary materials are expensive. Moreover, the process of ceramic tile veneer renovation is very complex, with more energy invested and severe resource expenditure. However, the use of elastic Heyi paint products is simple and easy to construct, and the direct cost savings are more than 60%

building energy conservation is an important part of implementing the strategy of sustainable development. It is the basic national policy to save energy and protect the environment. It is also the current global development trend. It is reasonable to believe that under the development environment of the popularization and application of external wall insulation, improving the energy-saving efficiency of building wall insulation system and extending the service life of the system will bring new opportunities to the external wall insulation industry. It is of great significance in practical development to actively promote building energy conservation and do a good job in building wall insulation
