Description

Technical Field

[0001] This utility model relates to the field of ultra-wear-resistant flooring technology, specifically to a water-based polyurethane mortar ultra-wear-resistant flooring. Background Technology

[0002] Flooring refers to the construction and treatment of existing ground using specific materials and processes to present a certain degree of decoration and functionality, such as epoxy self-leveling flooring, corundum wear-resistant flooring, epoxy terrazzo flooring, cement-based terrazzo, epoxy colored sand flooring, epoxy anti-static flooring, epoxy anti-slip flooring, polyurea anti-corrosion flooring, polyurethane flooring, silicone PU flooring, concrete sealing and curing agent flooring, etc.

[0003] The prior art patent document with publication number CN217711535U provides a water-based polyurethane mortar ultra-wear-resistant floor, including a base layer, an inorganic insulation layer laid on the upper end of the base layer, a waterproof layer laid on the upper end of the inorganic insulation layer, an organic insulation layer laid on the upper end of the waterproof layer, a pressure-resistant layer laid on the upper end of the organic insulation layer, a wear-resistant layer laid on the upper end of the pressure-resistant layer, and several evenly distributed anti-slip blocks on the upper end of the wear-resistant layer. Several fixing blocks are embedded on the upper end of the base layer, and the fixing blocks are located between the inorganic insulation layer and the base layer. The upper end of the fixing blocks is fixedly connected to the foundation pile. It can achieve the purpose of water and air permeability, high compressive load resistance, and reduced cracking and bulging of polyurethane mortar ultra-wear-resistant floor through the combined use of multiple materials. It is not only wear-resistant and durable, crack-proof and bulging-proof, but also waterproof and high-temperature resistant, which greatly improves the service life of polyurethane mortar ultra-wear-resistant floor.

[0004] Although the device has many beneficial effects, it still has the following problems: The existing double-layer insulation structure lacks an active thermal deformation design and relies solely on the tensile strength of the material itself to passively resist thermal stress. When the temperature difference between the floor and the substrate exceeds a certain level, the interlayer shear stress may still exceed the tolerance limit of the bonding interface, leading to the risk of bulging. Secondly, heat conduction is only achieved through the permeable holes in the base layer, lacking a directional heat conduction path. The floor surface relies solely on anti-friction blocks to increase friction and lacks a three-dimensional drainage structure, making it prone to forming a water film in rainy weather, which reduces the floor's coefficient of friction. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned problems of insufficient thermal expansion control and low heat transfer and drainage efficiency, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a water-based polyurethane mortar ultra-wear-resistant flooring. Hexagonal protrusions are pressed onto the surface of the butyl rubber roll, with gaps between adjacent protrusions. This allows the waterproof layer to undergo lateral displacement during thermal expansion, absorbing interlayer shear stress and preventing peeling damage to the bonding interface. Simultaneously, radial water-guiding grooves are engraved on the surface, with a hydrophobic PTFE coating sprayed inside to increase drainage speed. Combined with anti-slip particles, this forms a combined drainage and anti-slip function, improving the floor's friction coefficient in rainy weather. Aluminum sheets are pre-embedded within the silicon carbide heat-resistant layer, utilizing aluminum's high thermal conductivity to quickly transfer surface heat to the base layer, reducing the floor surface temperature.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0012] The wear-resistant layer has a flow guide groove on its top, and the flow guide groove has a radial structure;

[0013] The top of the heat-resistant layer is embedded with a heat sink, which is rectangular. The heat sink facilitates the heat transfer of the heat-resistant layer while improving the support and compressive strength of the heat-resistant layer.

[0014] The top of the waterproof layer has a square groove, and multiple protrusions are integrally formed inside the square groove. The protrusions have a hexagonal structure. A conductive mesh is embedded inside the waterproof layer. The conductive mesh conducts static electricity and improves the waterproof layer's resistance to pressure and cracking.

The PTFE coating accelerates the water flow rate while reducing the adhesion of dirt inside the guide channel, thereby reducing cleaning costs.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of water-based polyurethane mortar ultra-wear-resistant flooring has hexagonal protrusions pressed on the surface of butyl rubber rolls, with gaps formed between adjacent protrusions. This allows the waterproof layer to undergo lateral displacement during thermal expansion, absorbing interlayer shear stress and preventing peeling and damage to the bonding interface.

[0021] This type of water-based polyurethane mortar ultra-wear-resistant flooring features radial water-guiding grooves carved on the surface, with a hydrophobic PTFE coating sprayed inside the grooves to increase drainage flow rate. Combined with anti-slip particles, it forms a drainage and anti-slip composite function, improving the floor friction coefficient in rainy weather.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a water-based polyurethane mortar ultra-wear-resistant floor, including:

[0035] Please see Figures 1-5This embodiment of a water-based polyurethane mortar ultra-wear-resistant floor includes a base layer 500, which is made of C35 concrete. A waterproof layer 400 is bonded to the top of the base layer 500 via modified asphalt primer. The waterproof layer 400 is made of butyl rubber modified asphalt roll material. A heat-resistant layer 300 is bonded to the top of the waterproof layer 400 via self-adhesive tape. The heat-resistant layer 300 is made of water-based epoxy resin with added silicon carbide particles. A compression-resistant layer 200 is bonded to the top of the heat-resistant layer 300 via steel fiber reinforced concrete and an epoxy resin interface agent. The compression-resistant layer 200 is made of steel fiber reinforced concrete. A wear-resistant layer 100 is anchored to the top of the compression-resistant layer 200 via C20 fine aggregate concrete. The wear-resistant layer 100 is made of water-based polyurethane mortar with added nano-alumina, which increases the surface hardness of the wear-resistant layer 100 and enhances its wear resistance.

[0036] The top of the wear-resistant layer 100 is provided with a drainage channel, which has a radial structure, so that the surface of the wear-resistant layer 100 can quickly drain water in rainy weather.

[0037] The top of the heat-resistant layer 300 is embedded with a heat sink 310. The heat sink 310 is made of aluminum and is rectangular to increase the heat dissipation area. Together with the silicon carbide particles inside the heat-resistant layer 300, it transfers the surface temperature of the wear-resistant layer 100 to the base layer 500, thereby reducing the surface temperature of the wear-resistant layer 100.

[0038] The top of the waterproof layer 400 has a square groove, and multiple protrusions 410 are integrally formed and connected inside the square groove. The protrusions 410 have a hexagonal structure. After absorbing heat, the protrusions 410 expand and deform elastically through the gaps between the protrusions 410, absorbing the thermal stress of the waterproof layer 400. The waterproof layer 400 is embedded with a conductive mesh 420. The conductive mesh 420 is made of copper wire. Static electricity is conducted through the conductive mesh 420 and then transferred to the edge of the ground. The ground is connected through a lateral conductive strip buried at the edge of the ground to prevent the waterproof layer 400 from being broken down by static electricity. At the same time, because the conductive mesh 420 is completely sealed inside butyl rubber, it isolates oxygen and moisture, ensuring long-term conductive stability. The conductive mesh 420 does not damage the integrity of the waterproof layer 400 and adapts to the thermal expansion and contraction deformation of the ground.

[0039] It is worth noting that, in order to improve the drainage and impermeability of the base layer 500, multiple drainage channels 520 are specifically provided on the top of the base layer 500 to facilitate drainage and prevent water accumulation from aggravating thermal expansion and contraction. The drainage channels 520 are filled with permeable particles, which are permeable ceramsite. The top of the base layer 500 is covered with geotextile 510. The geotextile 510, together with the permeable particles, forms a capillary barrier to prevent groundwater backflow.

[0040] Furthermore, to enhance the compressive strength of the compressive layer 200, specifically, the compressive layer 200 is embedded with multiple hollow tubes. The hollow tubes are made of PVC and have a honeycomb structure, which disperses the concentrated load and improves the compressive strength. The gaps between the hollow tubes are filled with lightweight ceramsite concrete to reduce the self-weight of the compressive layer 200 and prevent the base layer 500 from settling and cracking.

[0041] Finally, to enhance the anti-slip properties of the wear-resistant layer 100, the top of the wear-resistant layer 100 is embedded with multiple anti-slip particles to improve its anti-slip performance. The inside of the drainage channel is coated with a PTFE coating to reduce the coefficient of friction inside the drainage channel, accelerate the drainage flow rate, and reduce dirt adhesion, thereby reducing cleaning costs.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-5 The specific application process of this embodiment of water-based polyurethane mortar ultra-wear-resistant flooring is as follows:

[0044] 1: Under normal circumstances, when the top of the wear-resistant layer 100 is subjected to pressure, the pressure impact energy is transferred to the compressive strength layer 200. The multiple honeycomb hollow tubes inside the compressive strength layer 200 will effectively disperse the pressure impact energy, reduce the elastic modulus of the floor, disperse the concentrated load, and improve the compressive strength of the floor.

[0045] 2: Under high temperature and sun exposure, the surface temperature of the wear-resistant layer 100 rises. At this time, the heat is transferred from top to bottom. When passing through the heat-resistant layer 300, the heat dissipation fins 310 on the top of the heat-resistant layer 300 will accelerate the heat dissipation efficiency and reduce the surface temperature of the wear-resistant layer 100. The top protrusions 410 of the waterproof layer 400 are heated and, together with the gaps between the multiple protrusions 410, undergo thermal expansion and elastic deformation to absorb the thermal stress of the waterproof layer 400, thus preventing the floor from cracking due to thermal expansion under high temperature and sun exposure.

[0046] 3. In rainy weather, the drainage channel on top of the wear-resistant layer 100 will quickly drain water from the surface of the wear-resistant layer 100. Combined with anti-slip particles, it will increase the friction coefficient of the wear-resistant layer 100. When water penetrates to the base layer 500, the drainage channel 520 on top of the base layer 500 will quickly drain the water. The geotextile 510 covering the top of the base layer 500, together with the permeable particles filled inside the drainage channel 520, forms a capillary barrier structure to prevent groundwater backflow.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
