The basic structure of ZL spray hard foaming and external heat insulation technology system independently developed by Beijing Zhenli Chaoshu Co., Ltd., passed the technical review organized by the Beijing Construction Committee in April 2004; and passed Beijing in January 2005. Project acceptance organized by the Municipal Construction Committee. This technology is the first in China to apply the solvent-free polyester ester hard foam material and polystyrene granule insulation slurry to form the external thermal insulation system. The innovation point is: using the emulsion primer treatment technology to solve the thermal insulation layer and the base layer bonding problem insulation layer Moisture-proof, waterproof and breathable problems; the special interface agent is used to solve the problem of bonding on the surface of the polyurethane foaming material; the technical problem of screed cracking of the polyurethane foaming material is solved by replacing the cement mortar with the rubber powder polystyrene granule insulation slurry; Construction technology combining prefabricated polyurethane angle die with on-site spray polyurethane. Technical Advantages In 2004, through the scientific research project “Research on the causes of cracks in the surface insulation system and the control technology of the external wall insulation systemâ€, the principle of anti-cracking technology of the flexible gradation of each structural layer was proposed creatively, and the wall was proposed.

The system has the following characteristics: hard foam atmosphere Brewing is an excellent thermal insulation material with a thermal conductivity of 0.0220.027 W (mK). The sprayed rigid foam polyurethane is a natural bond with the general wall material, without any adhesive and anchor. Adhesive material can form a continuous insulation layer, ensuring the integrity of the insulation material and the wall and effectively blocking the thermal bridge. Polyurethane is a flame retardant self-extinguishing material after adding a flame retardant. The surface of the polyurethane and the side of the door window are all tightly coated with a rubber powder polystyrene particle slurry with a burning performance grade of B1. When exposed to fire and heat, the heat is transferred to the inside less slowly and the heat is concentrated. The surface of the rubber powder polyphenyl granule slurry layer is beneficial to improve the fire resistance of the insulation layer. The sprayed hard foam polystyrene insulation layer is firmly combined with the base wall to form an organic whole with the base wall, without seams and without cavities, reducing wind pressure, especially negative wind pressure, on the outer wall of the high-rise building. The destruction of the system. The rigid foamed polyester material has excellent waterproof performance, can well block the penetration of water, and maintain the wall in a good and stable thermal insulation condition. The polyester ester moisture-proof primer used has the functions of moisture-proof, water-proof and vapor-permeable, especially in the case where the new wall in the wet rainy season is not completely dried after the completion of the new wall and the water-remaining wall of the base wall is more effective. Moreover, it has excellent permeability and firm adhesion, and can effectively prevent the residual ash of the base wall from adhering to the insulation layer. The interface of polyurethane is prepared by using a special polymer emulsion compounded with an appropriate amount of inorganic gelling material. The interface mortar also has a good bonding effect on the surface of the rigid foam polyurethane and the inorganic surface coating material, so that the polyurethane heat preservation and the rubber powder polyphenyl granule fireproof and vapor permeability transition layer can be firmly combined together. It has a protective effect on the surface of the rigid foam polyurethane to prevent yellowing and pulverization of the surface of the hard foamed polyurethane after exposure to sunlight. 6. Excellent protection performance of rubber powder polystyrene particles fire-retardant and super-vapor layer. The rubber powder polyphenylene granule slurry contains a large amount of inorganic materials, which can not only play a leveling effect after being compounded on the surface of the polyester ester hard foam insulation layer. It has many protective effects on the thermal insulation layer of the rigid foam polyurethane: it effectively prevents the aging effect of the ultraviolet h-line on the polyurethane layer; it compensates for the shortage of the material in the local part such as the door and the window. To avoid the generation of thermal bridges and enhance the thermal insulation effect of the system; the anti-cracking technical route conforming to the flexible layer-by-layer release stress can effectively prevent the occurrence of cracks in the protective surface layer and improve the stability and durability of the system; The insulation layer can save engineering construction and low cost of P; effectively block the fire of the fire source to the insulation layer of the rigid foam. Hard foam polyurethane spraying adopts mechanized operation, and the construction speed is fast and the efficiency is high. In order to ensure the straight line angle of the yin and yang angles, it is better to use the method of pre-fabricating polyurethane to reduce the material loss, which is beneficial to the straight yin and yang angles and the edge of the subsequent process, and improve the overall construction quality and efficiency. The technical route of controlling the crack by layer-by-layer gradient flexible release stress and controlling the difference in thermal conductivity of adjacent materials is adopted. The seam-free insulation layer on-site is seamless without joints, the dispersion stress of tb pre-formed plate is more uniform, and the crack resistance is reliable. So far, the on-site spraying of hard foam polyurethanes has been carried out in the northeast, northwestern China, central China, east China, southwest, west: b and other climatic zones, and has carried out millions of square meters in dozens of projects. application.
