Abstract
Description
Technical Field
[0012] ,
[0001] The utility model belongs to the technical field of decorative wall panels, and particularly relates to a non-combustible UHPC waterproof and heat-insulating decorative integrated board. Background Technique
[0002] In the prior art, organic and inorganic thermal insulation materials are mainly used for the exterior wall of decorative boards to achieve the effect of thermal insulation. Among them, the most commonly used organic thermal insulation materials are polystyrene and polyurethane. Although polystyrene and polyurethane have good thermal insulation effects and low costs, they are combustible materials with poor fire resistance. At the same time, they will release toxic gases and thick smoke when burning. Therefore, in order to improve the fire resistance of polystyrene and polyurethane, flame retardants are usually added, but this also increases the material cost. Inorganic thermal insulation materials such as rock wool and foam glass have the characteristics of good thermal insulation and good fire resistance. However, rock wool materials have certain hygroscopicity, insufficient waterproof performance, and the thermal insulation performance will also decline after moisture absorption; while foam glass materials do not absorb water, but are brittle, have poor impact resistance, and low strength. Content of the Utility Model
[0003] The purpose of the utility model is to provide a non-combustible UHPC waterproof and heat-insulating decorative integrated board to solve the technical problems raised in the above background technique.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A non-combustible UHPC waterproof and heat-insulating decorative integrated board includes a UHPC protective outer layer, a first heat-insulating layer, a second heat-insulating layer, a reinforcing layer, and a base layer; the UHPC protective outer layer has a "U" - shaped structure, and the first heat-insulating layer, the second heat-insulating layer, the reinforcing layer, and the base layer are sequentially arranged inside it from bottom to top. <00000l3>
[0006] Further, the thickness of the UHPC protective outer layer is 8 - 15 mm.
[0007] Further, the UHPC protective outer layer has a color.
[0008] Further, the first heat-insulating layer is an aerogel felt with a thickness of 8 - 15 mm.
[0009] Further, the second heat-insulating layer is a foamed brick embryo with a thickness of 17 - 23 mm.
[0010] Further, the reinforcing layer is an alkali-resistant fiberglass mesh and a special mortar applied on the alkali-resistant fiberglass mesh, and the thickness of the special mortar is 2 - 3 mm.
[0011] Further, the base layer is a crack-resistant putty.
[0012] The waterproof and heat-insulating principle of the utility model is:
[0013] Regarding thermal insulation: solar radiation heat is reflected by the UHPC protective outer layer. After the residual heat enters, it is blocked by the aerogel felt of the first insulation layer. At the same time, the foamed bricks of the second insulation layer further reduce heat conduction. The glass fiber mesh layer of the reinforcement layer suppresses thermal bridges to achieve synergistic thermal insulation.
[0014] Regarding waterproofness: water is blocked by the UHPC protective outer layer, while the infiltrated water vapor is absorbed by the foamed brick embryo of the second insulation layer. At the same time, the special mortar layer of the reinforcement layer blocks capillary rise. Finally, the anti-cracking putty of the base layer isolates the moisture of the wall base surface to achieve synergistic waterproofing.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This utility model comprises a UHPC protective outer layer, a first insulation layer, a second insulation layer, a reinforcement layer, and a base layer. The UHPC protective outer layer has excellent mechanical properties, can improve the strength of the board, and provides the main flame retardant, heat insulating, and waterproof functions. The aerogel felt of the first insulation layer effectively maintains heat and insulates. The foamed bricks of the second insulation layer reduce heat conduction, cooperate with the first insulation layer to improve thermal insulation performance, and absorb moisture to enhance waterproofing. The reinforcement layer provides internal support, improves the durability and strength of the board, and isolates the capillary rise of moisture, further enhancing waterproofing. The multi-layer structure works synergistically to achieve flame retardancy, heat insulation, and waterproofing of the decorative board. This utility model uses a colored UHPC protective outer layer, which not only ensures the performance of the decorative board but also provides an aesthetically pleasing decorative effect, avoiding the problem of shedding or fading of traditional paint after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 It is a structural diagram of the utility model;
[0018] In the accompanying drawings, 1-UHPC protective outer layer, 2-first thermal insulation layer, 3-second thermal insulation layer, 4-reinforcement layer, 5-base layer. DETAILED DESCRIPTION
[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in this specification are merely provided to help readers gain a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.
[0020] like Figure 1As shown in the figure, a non-combustible UHPC waterproof and heat-insulating decorative integrated board includes a UHPC protective outer layer 1, a first heat-insulating layer 2, a second heat-insulating layer 3, a reinforcing layer 4, and a base layer 5. The UHPC protective outer layer 1 has a "U" - shaped structure, and the first heat-insulating layer 2, the second heat-insulating layer 3, the reinforcing layer 4, and the base layer 5 are successively arranged inside it from bottom to top.
[0021] The UHPC protective outer layer 1 is made of UHPC, that is, ultra-high performance concrete material, and its thickness is 8 - 15 mm. UHPC is a cement-based material, mainly composed of inorganic minerals, belonging to Class A1 non-combustible materials. At the same time, it has an extremely low porosity and a highly dense microstructure, with excellent mechanical properties and durability. Its extremely low porosity and extremely high density form a physical barrier, effectively blocking the intrusion of liquid water and the diffusion of water vapor, having good waterproof performance, and playing a major role in fire retardant, heat insulation and waterproof functions.
[0022] The UHPC outer shell has a color. By adding different materials such as iron oxide red and titanium dioxide in the UHPC mixture, a colored outer shell can be obtained, thus obtaining decorative boards of different colors, achieving an aesthetic decorative effect. At the same time, through the self-colored UHPC outer shell, the problems of peeling or fading after long-term use in traditional painting can be avoided.
[0023] The first heat-insulating layer 2 is aerogel felt, and its thickness is 8 - 15 mm. Aerogel has an extremely low thermal conductivity and excellent thermal insulation performance, playing a major heat-insulating function.
[0024] The second heat-insulating layer 3 is a foamed brick embryo, and its thickness is 17 - 23 mm. The foamed brick embryo is a lightweight brick embryo formed by using industrial solid wastes such as desulfurized gypsum, slag, coal gangue, fly ash, and carbide slag as the main raw materials through a foaming process. It has certain strength and rigidity, can be used as an internal support framework to bear part of the internal stress, and improve the overall strength of the board. Moreover, the foamed brick embryo is a porous structure, containing a large number of tiny closed-cell bubbles, which can hinder heat conduction, play a heat preservation effect, cooperate with the aerogel felt for common heat preservation, and at the same time can reduce the usage amount of aerogel felt and lower the cost. In addition, the foamed brick embryo is mainly made of inorganic non-combustible materials, with good fire resistance, which can further enhance the fire resistance performance. Its internal microporous structure can also absorb a small amount of water vapor, playing a certain waterproof function.
[0025] The reinforcing layer 4 is an alkali-resistant fiberglass mesh and a special mortar applied on the alkali-resistant fiberglass mesh. The special mortar is crack-resistant mortar, and its thickness is 2 - 3 mm. The alkali-resistant fiberglass mesh and the special mortar are mixed to form the reinforcing layer 4. The alkali-resistant fiberglass mesh has good tensile strength and alkali resistance, which can prevent the mortar from shrinking and cracking and improve the durability. The mortar bonds the foamed brick blank and levels the surface of the foamed brick embryo at the same time, providing a good base surface for the subsequent construction of crack-resistant putty.
[0026] The base layer 5 is anti-cracking putty; the anti-cracking putty bridges the micro-cracks existing in the special mortar, and at the same time, fine leveling is performed on the special mortar to ensure that it is fully adhered to the building wall without hollows, forming a flat and smooth wall surface.
[0027] The principle of this utility model is:
[0028] Regarding thermal insulation: solar radiation heat is reflected by the UHPC protective outer layer 1. After the residual heat enters, it is blocked by the aerogel felt of the first insulation layer 2. At the same time, the foamed brick embryo of the second insulation layer 3 further reduces heat conduction, and the glass fiber mesh layer of the reinforcement layer 4 suppresses thermal bridges to achieve synergistic thermal insulation.
[0029] Regarding waterproofness: water is blocked by the UHPC protective outer layer 1, while the infiltrated water vapor is absorbed by the foamed brick embryo of the second insulation layer 3. At the same time, the special mortar layer of the reinforcement layer 4 blocks capillary rise. Finally, the anti-cracking putty of the base layer 5 isolates the moisture from the wall base surface, achieving synergistic waterproofing.
[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
