Description

Technical Field

[0001] This utility model relates to the field of floor structure technology, and in particular to a nano-polyurethane wear-resistant floor structure. Background Technology

[0002] With the increasing demands for floor performance in industrial and commercial buildings, flooring not only needs to possess good load-bearing capacity and wear resistance, but also needs to meet comprehensive performance requirements such as slip resistance, corrosion resistance, ease of maintenance, and long service life. Especially in high-load, frequent friction environments, traditional flooring materials are prone to surface wear, cracking, and dust generation, affecting performance and maintenance costs. Therefore, developing a high-strength, high-wear-resistant flooring structure with self-healing capabilities has become an urgent need for the industry.

[0003] Currently, conventional wear-resistant flooring often uses materials such as corundum or epoxy resin for surface treatment. While this can improve wear resistance to some extent, it still suffers from defects such as insufficient surface density, poor crack resistance, and inability to self-repair after damage. Furthermore, traditional flooring is prone to generating localized high temperatures under long-term friction, leading to material softening and failure. It also lacks effective surface functionalization design, resulting in limited anti-slip and heat dissipation performance, making it difficult to meet the stability and safety requirements of high-intensity use scenarios. Therefore, there is an urgent need for a novel wear-resistant flooring structure that combines nano-reinforcement, self-healing mechanisms, and surface microstructure design to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nano-polyurethane wear-resistant flooring structure. This structure is formed by combining corundum aggregate and nano-silica sol to create a dense structure, and self-healing capsules are introduced into the wear-resistant layer to enhance the wear resistance and self-healing ability of the flooring. Combined with nano-embossed textures, it enhances anti-slip properties and heat dissipation, effectively extending service life and reducing maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nano-polyurethane wear-resistant flooring structure, comprising a concrete base layer, a reinforcing layer at the top of the concrete base layer, the reinforcing layer being nano-silica sol, a curing layer at the top of the reinforcing layer being a lithium-based curing agent, a wear-resistant layer at the top of the curing layer being a polyurethane modified curing agent, and micro-textures on the upper surface of the wear-resistant layer.

[0006] Furthermore, a support rod is fixedly connected inside the concrete base layer, and a steel mesh is fixedly connected to the upper end of the support rod.

[0007] Furthermore, the reinforcing layer is internally encapsulated with diamond aggregate to form a wear-resistant skeleton.

[0008] Furthermore, the wear-resistant layer contains a repair capsule, the wall material of which is urea-formaldehyde resin, which prevents the core material from reacting prematurely with the polyurethane curing agent. The core material is a nano-polyurethane prepolymer and a catalyst.

[0009] Furthermore, the microtexture is arranged in a hexagonal honeycomb pattern using nanoimprinting technology, and the surface of the microtexture is coated with a transparent nano-ceramic coating.

[0010] Furthermore, the outer wall of the steel mesh is fixedly connected to the inner wall of the concrete base layer.

[0011] This utility model has the following beneficial effects: 1. In this invention, high-hardness 120-mesh diamond aggregate is spread during the initial setting stage of concrete, and combined with the penetration reaction of nano-silica sol materials, a dense CSH gel structure is formed, giving the floor surface excellent wear resistance, compressive strength, and chemical corrosion resistance. Simultaneously, repair capsules are introduced into the subsequently applied polyurethane modified curing agent layer, enabling automatic repair when micro-cracks occur, effectively restoring more than 70% of the wear resistance, greatly slowing down the aging and damage rate of the floor, and thus significantly extending its service life.

[0012] 2. In this invention, a hexagonal honeycomb microtexture structure is constructed on the floor surface using nanoimprinting technology. This not only enhances the anti-slip performance and friction resistance of the floor but also effectively disperses heat in high-friction environments, preventing localized high temperatures from causing material softening and failure, thus improving safety. Simultaneously, the self-healing capsule mechanism reduces the frequency and cost of maintenance during floor use, making it suitable for high-intensity industrial and commercial environments, and demonstrating good economic benefits and application prospects.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-3 An embodiment of this utility model provides a nano-polyurethane wear-resistant flooring structure, comprising a concrete base layer 1, a support rod 6 fixedly connected inside the concrete base layer 1, a steel mesh 7 fixedly connected to the upper end of the support rod 6, the outer wall of the steel mesh 7 fixedly connected to the inner wall of the concrete base layer 1, a reinforcing layer 2 provided at the top of the concrete base layer 1, the reinforcing layer 2 being nano-silica sol, the reinforcing layer 2 containing corundum aggregate 8 to form a wear-resistant skeleton, a curing layer 3 provided at the top of the reinforcing layer 2, the curing layer 3 being a lithium-based curing agent, and a wear-resistant layer 4 provided at the top of the curing layer 3.

[0017] Specifically, during the pouring of this concrete floor, the ground is first thoroughly cleaned, followed by the binding of steel mesh 7 to enhance the tensile strength of the overall structure. Next, formwork is erected and the concrete base layer 1 is poured. When the concrete enters the initial setting stage, 120-mesh diamond aggregate 8 is evenly spread, with a dosage of no less than 1 kg per square meter, forming a hard and wear-resistant skeleton structure. Simultaneously, nano-silica sol material is evenly sprayed onto the concrete surface using a spray bottle or sprayer. Nano-silica sol can effectively penetrate and fill the tiny pores in the concrete, increasing its density. The silica in the silica sol reacts with the calcium hydroxide produced during cement hydration to generate a stable CSH gel, thus forming a nano-reinforcing layer 2 on the surface, significantly improving the surface hardness and durability of the floor. After the concrete has fully cured, the surface is polished, followed by the even spraying of a lithium-based curing agent. The ground is kept moist for approximately 4 hours. When the surface becomes viscous, it is rinsed clean with water and any standing water is thoroughly removed. It is then allowed to air dry for at least 24 hours to form a stable cured layer 3.

[0018] Reference Figure 1 and Figure 4 The wear-resistant layer 4 is a polyurethane modified curing agent. The wear-resistant layer 4 contains a repair capsule 9. The wall material of the repair capsule 9 is urea-formaldehyde resin, which prevents the core material from reacting prematurely with the polyurethane curing agent. The core material is a nano-polyurethane prepolymer and a catalyst. The upper surface of the wear-resistant layer 4 has micro-textures 5. The micro-textures 5 are arranged in a hexagonal honeycomb pattern by nano-imprinting technology. The surface of the micro-textures 5 is coated with a transparent nano-ceramic coating.

[0019] Specifically, the polyurethane modified curing agent containing repair capsules 9 is evenly applied to the surface of the cured layer 3 using a scraper or roller coating method. After drying, it forms the wear-resistant layer 4. The wall material of the repair capsules 9 is made of urea-formaldehyde resin, and the core material is a mixture of nano-polyurethane prepolymer and catalyst. When the wear-resistant layer 4 develops microcracks due to friction or impact, the capsule wall ruptures, the core material flows out and reacts with moisture in the air, rapidly curing into a polyurethane elastomer, thereby automatically filling the cracks and achieving the self-healing function of the floor. This mechanism allows the floor to recover more than 70% of its wear resistance after minor damage, significantly extending its service life and reducing maintenance costs.

[0020] Finally, nanoimprinting technology is used on the surface of the wear-resistant layer 4 to construct a continuous nanoscale microtexture structure 5 with a hexagonal honeycomb arrangement. The surface of the microtexture 5 is coated with a transparent nano-ceramic coating to reduce wear. This biomimetic texture not only increases the coefficient of friction of the floor surface and enhances its anti-slip performance, but also effectively disperses heat during friction, preventing localized high temperatures from causing the polyurethane material to soften and fail, thereby further improving the overall performance and safety of the floor.

[0021] Working principle: During the pouring of this concrete base, the cleaned ground is first reinforced with steel mesh 7, then the formwork is erected and the concrete base 1 is poured. During the initial setting period of the concrete, 120-mesh diamond aggregate 8 is spread evenly on the surface of the initially set concrete at an average rate of no less than 1 kg per square meter. Then, nano-silica sol material is quantitatively and evenly sprayed onto the concrete surface using a sprayer or sprayer. The nano-silica sol fills the micropores, increases the density, and reacts with the cement hydration product Ca(OH)2 to generate CSH gel, forming a nano-reinforced layer 2; the diamond aggregate 8 forms a wear-resistant skeleton. After the concrete base 1 is properly cured, a lithium-based curing agent is evenly sprayed onto the polished reinforced layer 2. After keeping the ground moist for 4 hours, when the surface becomes viscous, the entire surface is washed with clean water to remove all standing water. It is then allowed to dry naturally for more than 24 hours to form a cured layer 3. Finally, a polyurethane modified curing agent containing repair capsules 9 is evenly applied to the surface of the reinforced layer 2 using a scraper or roller. After drying, a wear-resistant layer 4 is formed. Finally, a continuous nanoscale microtexture 5 is constructed on the surface of the wear-resistant layer 4 using nanoimprinting technology in a hexagonal honeycomb arrangement. When the wear-resistant layer 4 develops microcracks due to friction or impact, the wall material of the repair capsule 9 breaks, the core material flows out and reacts with moisture in the air, quickly curing to form a polyurethane elastomer that fills the crack gaps.
