Description

Technical Field

[0001] This utility model belongs to the field of exterior wall brick technology, specifically relating to an exterior wall brick with hydrophobic properties. Background Technology

[0002] Exterior wall tiles are mainly used for the decoration and protection of building exteriors. They not only decorate the entire building but also play a vital role in protecting the wall structure due to their acid and alkali resistance and stable physical and chemical properties. Most exterior wall tiles are bonded together with epoxy resin adhesive. However, epoxy resin adhesive easily loses its adhesiveness due to rainwater erosion, leading to tile detachment. Besides affecting the aesthetics of the tiles, detached tiles also pose certain safety hazards. Most exterior wall tiles lack water-repellent properties, allowing rainwater to easily enter the joints between them, eventually causing tiles to detach. Therefore, a new type of exterior wall tile with hydrophobic properties is designed to overcome these technical defects. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an exterior wall brick with hydrophobic properties. This exterior wall brick aims to solve the technical problem that most exterior wall bricks under the existing technology do not have the function of hydrophobic drainage, which makes it easy for rainwater to enter the joints between the exterior wall bricks when it rains, and over time, it will easily lead to the detachment of the exterior wall bricks.

[0005] (2) Technical solution

[0006] To solve the above-mentioned technical problems, this utility model provides an exterior wall brick with hydrophobic properties. The exterior wall brick includes a base brick, a sound-absorbing layer is fixedly connected to the outer surface of the base brick, a face brick is installed on the side of the sound-absorbing layer away from the base brick, a groove is provided on the side of the face brick away from the sound-absorbing layer, the outer surface of the face brick is coated with a superhydrophobic coating, slots are provided on the left and top surfaces of the sound-absorbing layer, and clips are installed on the right and bottom surfaces of the sound-absorbing layer. The material of the sound-absorbing layer is a ceramic aluminum sound-absorbing board.

[0007] When using exterior wall tiles with this technical solution, during installation, the tiles are arranged so that the retaining strip of one tile is inserted into the groove of another, sealing the gaps and forming a unified sound-absorbing layer. This ensures the sound-absorbing effect of the tiles. Furthermore, the superhydrophobic coating provides excellent waterproofing. The special structure of the superhydrophobic material prevents water droplets from remaining on the tile surface, achieving a waterproof effect; water droplets on the tiles will quickly roll off. This process removes attached dust and dirt, achieving a self-cleaning effect. It effectively prevents pollutants from adhering to the coating surface, ensuring the aesthetics of the exterior wall tiles during use. Through the groove design, when raindrops fall on the tile surface, they quickly slide within the tile to the edge. Due to the groove, the tile edge curves upwards, allowing the raindrops to slide directly off the edge and fall away. This reduces or prevents rainwater from flowing into the joints of the exterior wall tiles, minimizing the loss of adhesion and detachment of the epoxy resin adhesive in the joints due to rainwater erosion, thus ensuring the safety of the exterior wall tiles during use.

[0008] Preferably, the sound-absorbing layer has mounting grooves on both the front and back sides, and both sides are grid-shaped. The grid-shaped sound-absorbing layer enhances the adhesion between the sound-absorbing layer and the base and top bricks, making the connection between the sound-absorbing layer, base brick, and top brick more secure.

[0009] Furthermore, the back of the bottom brick has a groove, and the groove is mesh-like. The mesh-like groove makes the bottom brick more stable when installed with brick adhesive.

[0010] Furthermore, a fiberglass reinforcing mesh is embedded inside the outer bottom brick. This fiberglass reinforcing mesh enhances the strength of the bottom brick and ensures its service life.

[0011] (3) Beneficial effects

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] During installation, this utility model arranges the exterior wall tiles so that the locking strip of one tile is inserted into the slot of another, sealing the gaps between the tiles and forming a unified sound-absorbing layer. This ensures the sound-absorbing effect of the tiles. The superhydrophobic coating provides excellent waterproofing, as the special structure of the superhydrophobic material prevents water droplets from remaining on the tile surface, thus achieving a waterproof effect. Water droplets on the tiles quickly roll off, reducing water damage. It removes adhering dust and dirt, achieving a self-cleaning effect. It effectively prevents pollutants from adhering to the coating surface, ensuring the aesthetics of the exterior wall tiles during use. Through the setting of the groove, when raindrops fall on the surface of the tiles, the raindrops quickly slide within the tiles to the edges. Under the action of the groove, the edges of the tiles are curved and raised, and the raindrops slide directly out and fall off from the edges of the tiles. This reduces or avoids the amount of rainwater flowing into the joints of the exterior wall tiles, and reduces the risk of the epoxy resin adhesive in the joints losing its adhesion and falling off due to rainwater erosion, ensuring the safety of the exterior wall tiles during use.

[0022] This specific embodiment is an exterior wall brick with hydrophobic properties, and its structural schematic diagram is as follows. Figures 1-7As shown, the exterior wall brick includes a base brick 1, a sound-absorbing layer 3 is fixedly connected to the outer surface of the base brick 1, a face brick 5 is installed on the side of the sound-absorbing layer 3 away from the base brick 1, a groove 6 is provided on the side of the face brick 5 away from the sound-absorbing layer 3, the outer surface of the face brick 5 is coated with a superhydrophobic coating 2, slots 4 are provided on the left side and top surface of the sound-absorbing layer 3, and clips 8 are installed on the right side and bottom surface of the sound-absorbing layer 3. The material of the sound-absorbing layer 3 is a ceramic aluminum sound-absorbing board.

[0023] The sound-absorbing layer 3 has mounting grooves 7 on both its front and back sides, and both sides are grid-shaped. This grid-shaped design enhances the adhesion between the sound-absorbing layer 3 and the base brick 1 and the top brick 5, making the connection between the sound-absorbing layer 3, base brick 1, and top brick 5 more secure. The back of the base brick 1 has a pressure groove 9, which is mesh-like. This mesh-like pressure groove 9 makes the base brick 1 more stable when installed with brick adhesive.

[0024] In addition, a glass wire reinforcing mesh 10 is embedded inside the outer bottom brick 1. The installation of the glass wire reinforcing mesh 10 can improve the strength of the bottom brick 1 and ensure its service life.

[0025] Working Principle: When using the exterior wall tiles of this technical solution, during installation, the tiles are arranged so that the retaining strip 8 of one tile is inserted into the groove 4 of another, sealing the gaps between the tiles and ensuring the sound-absorbing layer 3 of the installed tiles forms a unified whole, guaranteeing the sound-absorbing effect. The superhydrophobic coating 2 provides excellent waterproof performance to the surface of the exterior wall tiles. This is because the superhydrophobic material has a special surface structure that prevents water droplets from remaining on the tile surface, thus achieving a waterproof effect. Water droplets on the exterior wall tiles will quickly roll off. The raindrops fall, carrying away the attached dust and dirt, achieving a self-cleaning effect. This effectively prevents pollutants from adhering to the coating surface, ensuring the aesthetics of the exterior wall tiles during use. With the setting of the groove 6, when raindrops fall on the surface of the tile 5, the raindrops quickly slide to the edge of the tile 5. Under the action of the groove 6, the edge of the tile 5 is curved and raised, and the raindrops slide directly out and fall off from the edge of the tile 5, reducing or avoiding the amount of rainwater flowing into the joints of the exterior wall tiles. This also reduces the risk of the epoxy resin adhesive in the joints of the exterior wall tiles losing its adhesiveness and falling off due to rainwater erosion, ensuring the safety of the exterior wall tiles during use.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
