Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall waterproof coatings, and more specifically to an exterior wall waterproof polyurethane coating structure. Background Art

[0002] Exterior wall waterproof polyurethane coating is a waterproof coating that uses polyurethane resin as the main ingredient. It effectively prevents moisture penetration and protects the building from moisture damage by forming a strong and flexible coating on the surface of the building's exterior wall. It is widely used in exterior wall waterproofing treatment of buildings.

[0003] Most of the existing exterior wall coatings use a single polyurethane coating for waterproofing, but the waterproof effect is not ideal, which can cause rainwater to erode the inside of the wall, causing moisture in the house. In addition, the sound insulation effect of the coating structure itself is not ideal, which affects the indoor living environment and causes great trouble to the user.

[0004] In addition, the existing exterior wall waterproof coating lacks certain heat insulation properties. When the external environment is hot, it is very easy to be invaded by high temperature, which in turn increases the indoor temperature and causes certain discomfort to personnel. Moreover, its own resistance is also poor. When in use, it is very easy to cause wall damage due to external impact. It will also cause certain cracks due to long-term use, which can easily affect the aesthetics of the exterior wall.

[0005] In view of this, we propose a waterproof polyurethane coating structure for the exterior wall. Utility Model Content

Multiple fixed columns can stably support the inside of the cement base layer 100. The fiber layer 1 200 and the fiber layer 2 260 are both made of glass fiber, which is convenient for improving the uniformity of its application.

[0030] Furthermore, a plurality of circular holes 230 are opened on the right outer wall of the fiber layer 1 200 , and a sound insulation layer 240 is applied on the right side of the fiber layer 1 200 , and the sound insulation layer 240 fills the plurality of circular holes 230 .

[0032] Furthermore, an adhesive layer 250 is applied to the side wall of the fiber layer 1 200 on the basis of the sound insulation layer 240 , and a fiber layer 2 260 is adhered to the side wall of the adhesive layer 250 .

[0033] In some embodiments: the adhesion layer 250 is generally composed of a polymer resin, a solvent, a filler, etc., and its main function is to enhance the adhesion between the coating and the substrate and improve the durability and stability of the coating.

[0034] Furthermore, the second fiber layer 260 is in a mesh shape, and the waterproof film 270 is evenly adhered to the side wall of the second fiber layer 260, so as to further improve the waterproof performance of the coating.

[0035] It is worth noting that a waterproof layer 280 is applied on the right side of the waterproof film 270 , and a reinforcement layer 300 is sprayed on the right outer wall of the waterproof layer 280 , which is usually made of polyurethane.

[0036] It is worth noting that the reinforcement layer 300 is a superelastic material composed of polyurethane and polyurea elastomer, and a heat-resistant layer 310 is coated on the right side of the reinforcement layer 300.

When in use, the fiber layer 200 can cooperate with the sound insulation layer 240 inside the circular hole 2230 on the outer wall to effectively reduce the propagation of external noise, improve the sound insulation effect of the building, and create a quieter and more comfortable indoor environment. The setting of multiple circular holes can better increase the filling amount of the sound insulation coating, thereby enhancing its sound insulation. The fiber layer 200 can be installed on the outer wall of the cement base using multiple fixing columns 220, thereby better improving its stable support for use.

[0040] Secondly, when in use, the reinforcing layer 300 composed of polyurethane and polyurea elastomer has good elasticity and flexibility, can adapt to the changes and expansion of the exterior wall surface, reduce the risk of cracking or falling off, and can also better increase a certain impact resistance, reduce the degree of damage to the wall caused by external impact, and because polyurethane and polyurea elastomers themselves have good waterproof properties, the super elastic material in the exterior wall coating structure can also more effectively prevent moisture penetration, form a good waterproof barrier, and thus improve its practical performance.
