[0002] Microcement is a highly innovative new architectural coating, demonstrating remarkably high adhesion, allowing it to easily adhere to a wide variety of substrates, from solid concrete to pristine brick and stone. Microcement also boasts exceptional wear and compression resistance, making it particularly suitable for high-traffic areas, where it can remain in excellent condition despite frequent traffic and activity.

[0003] Microcement paint is essentially a unique paint made from a solid cement base, carefully blended with polymers, bright pigments, and a variety of other additives. It has an extremely delicate surface texture, can present a strong decorative effect, and gives people the ultimate visual enjoyment. Microcement paint is not just a beautiful visual effect, it also has amazing durability and powerful functionality. Whether facing the erosion of time or various complex usage environments, it can demonstrate excellent quality and reliable performance.

[0004] Chinese utility model patent publication number: CN 215254259 U, discloses: a wear-resistant micro-cement coating floor structure, wherein the surface of the anti-cracking mortar layer of the wear-resistant micro-cement coating floor structure is sequentially provided with a micro-cement base material layer and a micro-cement surface material layer. Since the micro-cement material itself has strong wear resistance and high pressure resistance, when the floor structure is subjected to high-frequency, long-term friction and trampling, the surface of the floor structure is not easily scratched or damaged and cracked. In addition, the micro-cement material has a good decorative effect, which meets the user's demand for modern or minimalist decoration and effectively enhances the beauty and design sense of the floor structure. However, the wear-resistant micro-cement coating floor structure does not have a buffer structure, cannot effectively buffer the impact of heavy objects and daily pressure, and reduce damage to the entire floor structure. The protective coating is a mixture of polyurethane water-based clear topcoat and floor protection wax, and has insufficient wear resistance. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a wear-resistant micro-cement coating floor structure, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by the utility model is: a wear-resistant micro-cement coating floor structure, which is arranged on the surface of a hardened floor, a leveling layer is arranged on the upper end of the hardened floor, a hardened layer is laid on the upper end of the leveling layer, a buffer layer is laid on the upper end of the hardened layer, a hanging mesh is laid on the upper end of the buffer layer, a reinforcement layer is laid on the upper end of the hanging mesh, a micro-cement surface layer 1 is laid on the upper end of the reinforcement layer, a micro-cement surface layer 2 is laid on the upper end of the micro-cement surface layer 1, and the upper end of the micro-cement surface layer 2 is coated with a wear-resistant layer.

[0007] Preferably, the leveling layer is a cement mortar layer, the cement strength used in the leveling layer is greater than C35, medium sand is selected and the mud content is ≤3%, and the thickness of the leveling layer is 10mm to 15mm.

[0008] Through the above technical solution, the leveling layer uses cement with a strength greater than C35 and excellent compressive resistance. Medium sand with a mud content of ≤3% is selected to ensure good workability of the mortar. During the construction process, the cement mortar can be applied and leveled more evenly, which helps to improve construction quality and efficiency.

[0009] Preferably, the hardened layer is a cement mortar layer, the strength of the hardened layer is greater than C45, and the thickness of the hardened layer is 3 mm to 5 mm.

[0010] Through the above technical solution, the hardened layer uses cement mortar with a strength greater than C45, which greatly improves the bearing capacity of the ground. Combined with the leveling layer, it can fully fill the tiny unevenness on the surface of the hardened ground and enhance the stability and reliability of the entire ground structure at the foundation level.

[0011] Preferably, the buffer layer is made of a mixture of rubber particles and polyurethane adhesive, the rubber particles have a particle size of 2mm to 5mm, and account for 40% to 60% of the total volume of the buffer layer, and the buffer layer has a thickness of 5mm to 10mm.

[0012] Through the above technical solution, the buffer layer is made of a mixture of rubber particles and polyurethane adhesive. When an external force impacts the ground, such as a heavy object falling or a sharp object hitting, the rubber particles can deform due to their good elasticity and effectively absorb the impact energy, greatly reducing problems such as cracks and damage in the ground caused by the impact, and significantly extending the service life of the entire ground structure. The polyurethane adhesive in the buffer layer firmly bonds the rubber particles, ensuring the integrity of the buffer layer, while giving it good bonding properties with the underlying hardened layer.

[0013] Preferably, the hanging net is made of glass fiber mesh with a mesh number of 10 to 16, the reinforcement layer is made of epoxy resin glue, and the total thickness of the hanging net and the reinforcement layer is 2 mm to 3 mm.

[0014] Through the above technical solution, a hanging net made of glass fiber mesh cloth is set up, which has high strength and excellent alkali resistance. When the ground structure is affected by factors such as uneven settlement and temperature changes, the hanging net of glass fiber mesh cloth can enhance the integrity of the entire structure, effectively inhibit the generation and expansion of cracks, and prevent cracks in the ground from spreading to the surface. The reinforcement layer uses epoxy resin glue to fully impregnate the hanging net of glass fiber mesh cloth, forming excellent bonding strength with the upper and lower materials, providing a solid and stable supporting base for the microcement surface layer.

[0015] Preferably, the microcement surface layer 1 and the microcement surface layer 2 are both made by mixing microcement, water-based resin emulsion and pigment, wherein the water-based resin emulsion accounts for 25% to 35% of the total mass of the coating, the cement-based material used in the microcement has a fineness of 300 mesh to 500 mesh, the thickness of the microcement surface layer 1 is 2.5 mm to 3 mm, and the thickness of the microcement surface layer 2 is 2 mm to 2.5 mm.

When the ground expands or contracts due to temperature changes, or when it undergoes slight deformation, the microcement surface layer can adapt to such changes through its own flexibility, effectively reducing the occurrence of cracks and ensuring the integrity of the ground. Microcement surface layer one and microcement surface layer two are constructed in a layered manner, which not only ensures that the entire microcement surface layer has sufficient thickness and wear resistance, but also reduces the problem of internal stress concentration through layered construction.

[0017] Preferably, the wear-resistant layer is made of polyurethane wear-resistant coating with ceramic microbeads and silicon carbide particles added thereto, the particle size of the ceramic microbeads is 0.1mm-0.3mm, the particle size of the silicon carbide particles is 0.05mm-0.2mm, and the thickness of the wear-resistant layer is 1mm-2mm.

[0018] Through the above technical solution, the wear-resistant layer is made of polyurethane wear-resistant coating with ceramic microbeads and silicon carbide particles added. The ceramic microbeads and silicon carbide particles are evenly distributed in the polyurethane wear-resistant coating, which greatly improves the hardness and wear resistance of the wear-resistant layer. It can effectively resist wear, protect the microcement surface layer and the underlying structure from damage, and reduce the maintenance and replacement costs caused by wear.

When an external force impacts the ground, such as a heavy object falling or a sharp object hitting it, the rubber particles can deform with their excellent elasticity, effectively absorbing the impact energy, greatly reducing the problems of cracks and damage in the ground caused by the impact, and significantly extending the service life of the entire floor structure. The polyurethane adhesive in the buffer layer firmly bonds the rubber particles, ensuring the integrity of the buffer layer, while also ensuring good bonding performance with the underlying hardened layer.

[0021] 2. The wear-resistant micro-cement coating floor structure is equipped with a glass fiber mesh, which has high strength and excellent alkali resistance. When the ground structure is affected by factors such as uneven settlement and temperature changes, the glass fiber mesh can enhance the integrity of the entire structure and effectively inhibit the generation and expansion of cracks. The reinforcement layer uses epoxy resin glue to fully impregnate the glass fiber mesh, forming excellent bonding with the upper and lower materials, providing a solid and stable supporting base for the micro-cement surface layer. Both the first and second micro-cement surface layers adopt a specific formula, with a high proportion of water-based resin emulsion. It can significantly improve the flexibility and adhesion of microcement. When the ground expands or contracts due to temperature changes, or when it undergoes slight deformation, the microcement surface layer can adapt to such changes through its own flexibility, effectively reducing the occurrence of cracks and ensuring the integrity of the ground. The wear-resistant layer is made of polyurethane wear-resistant coating with ceramic microbeads and silicon carbide particles added. The ceramic microbeads and silicon carbide particles are evenly distributed in the polyurethane wear-resistant coating, which greatly improves the hardness and wear resistance of the wear-resistant layer, can effectively resist wear, protect the microcement surface layer and the underlying structure from damage, and reduce the maintenance and replacement costs caused by wear.
