[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a food safety flooring, which includes a floor base layer 1, an antibacterial and breathable layer 2, a mortar material bonding layer 3, a structural reinforcement layer 4, and a paint protective layer 5 in sequence from bottom to top. The floor base layer 1 is provided with a dry hard cement mortar filling layer.

[0024] In this embodiment, the subfloor base 1 serves as the structural foundation, bearing the pressure from the upper layers. Simultaneously, the internal dry-hardened cement mortar filling layer provides the necessary strength and stability. The polyurea waterproof layer 301, combined with the antibacterial and breathable layer 2 and the structural reinforcement layer 4, acts as a waterproof layer, preventing moisture penetration into the underlying structure and protecting the subfloor from water damage. The steel fiber mortar mixture layer 401 enhances the compressive strength and toughness of the subfloor. This layer effectively disperses pressure and impact from the ground, reducing cracking and enhancing structural stability. The protective paint layer 5 protects the subfloor surface from abrasion and chemical corrosion. The additional oil-resistant paint layer 501 provides extra protection, ensuring the subfloor maintains its aesthetics and performance over long-term use.

[0025] The antibacterial breathable layer 2 includes an antibacterial breathable layer 2 and a fiberglass cloth layer 201. An adhesive layer is provided between the antibacterial breathable layer 2 and the fiberglass cloth layer 201. The surface of the antibacterial breathable layer 2 is provided with a silver ion antibacterial layer 204 and a number of densely distributed permeable pores 203. The surface of the fiberglass cloth layer 201 is provided with an epoxy resin layer 202. The epoxy resin layer 202 is connected to the silver ion antibacterial layer 204 through the adhesive layer.

[0026] In this embodiment, the antibacterial breathable layer 2 contains antibacterial materials, such as silver ions, which effectively inhibit the growth of microorganisms such as bacteria and fungi, and provides a certain degree of breathability through the permeable pores 203. This breathability facilitates moisture evaporation and prevents moisture accumulation within the base layer. The permeable pores 203 allow for the exchange of air and moisture. This effectively reduces mold and rot caused by moisture in the substrate and ensures the dryness and health of the floor. An adhesive layer is located between the antibacterial breathable layer 2 and the fiberglass cloth layer 201, and its function is to enhance the adhesion between the two, ensuring a tight bond between the antibacterial breathable layer 2 and the fiberglass cloth layer 201, thereby improving the stability and durability of the overall structure. The fiberglass cloth layer 201 adds strength and crack resistance to the structure, distributing the load applied to the floor, reducing local stress concentration, and lowering the risk of cracking in the floor material. Coloring and abrasion resistance are enhanced by the epoxy resin layer 202, which improves the mechanical strength and chemical resistance of the floor. In addition, the bonding between epoxy resin and silver ion antibacterial layer 204 combines antibacterial and waterproof properties, further ensuring the cleanliness and hygiene of the floor.

[0027] In this embodiment, the protective paint layer 5 is located on the top layer and its main function is to provide wear-resistant protection for the surface, preventing wear, scratches, and impacts on the floor during daily use. It enhances the aesthetics of the floor and provides a certain degree of chemical resistance. Adhesive 502 is used to connect the oil-resistant paint layer 501 and the anti-corrosion layer, ensuring good adhesion between the two. The anti-corrosion layer prevents corrosion of the floor by chemicals and moisture, extending the floor's service life. This layer is typically made of specially formulated anti-corrosion materials that can resist the erosion of oil, acids, alkalis, and other chemicals. The selection and design of the water-absorbing layer take into account moisture management. It can absorb and store small amounts of moisture, preventing moisture from accumulating on the floor surface and thus reducing damage caused by moisture. Furthermore, the absorbent layer 505 can also mitigate floor temperature fluctuations to some extent. The interface agent 504 is located between the absorbent layer 505 and the anti-corrosion layer, enhancing the bonding force between the two and ensuring that the absorbent layer 505 adheres tightly to the anti-corrosion layer, preventing peeling due to temperature changes or pressure during use.

[0028] The protective paint layer 5 comprises, from top to bottom, an oil-resistant paint layer 501, an anti-corrosion layer, and a water-absorbing layer 505. An adhesive 502 is provided between the oil-resistant paint layer 501 and the anti-corrosion layer. The water-absorbing layer 505 is connected to the anti-corrosion layer. An interface agent 504 is provided at the connection between the water-absorbing layer 505 and the anti-corrosion layer.

[0029] In this embodiment, the construction method involves first preparing and leveling the ground, ensuring the base layer is dry and firm, and then applying a dry-hardened cement mortar filling layer to the base layer 1. An antibacterial breathable layer 2 is then bonded to the dry-hardened cement mortar filling layer, with an adhesive layer added between it and the fiberglass cloth layer 201. The layout design of the antibacterial breathable layer 2 surface, the silver ion antibacterial layer 204, and the permeable pores 203 is carefully considered. A fiberglass cloth layer 201 is applied to the antibacterial breathable layer 2, followed by an epoxy resin layer 202. A polyurea waterproof layer 301 is applied to the surface of the fiberglass cloth layer 201, ensuring that the thickness of the polyurea waterproof layer 301 is less than that of the epoxy resin layer 202. A steel fiber mortar mixture layer 401 with a thickness of 0.3 mm is added to the bottom of the absorbent layer 505 to enhance the structural performance of the floor. An anti-corrosion layer, an absorbent layer 505, and an oil-resistant paint layer 501 are then applied sequentially to the structural layer, using a suitable adhesive 502 and interface agent 504 to ensure good adhesion between the layers. The antibacterial and breathable layer 2 provides antibacterial properties through the silver ion antibacterial layer 204 and the permeable pores 203, while maintaining gas flow, preventing moisture accumulation, and reducing the risk of microbial growth.

[0030] Furthermore, the mortar material bonding layer 3 includes a polyurea waterproof layer 301, which is disposed on the surface of the fiberglass cloth layer 201, and the thickness of the polyurea waterproof layer 301 is less than the thickness of the epoxy resin layer 202.

[0031] Polyurea is a high-performance polymer material with excellent physical and chemical properties, widely used in waterproofing and protective coatings. In this design, the polyurea waterproof layer 301 is disposed on the surface of the fiberglass cloth layer 201. Its main function is to provide excellent waterproofing, prevent moisture from penetrating to the underlying layers, and protect the structure from moisture and water damage. Polyurea materials can form a robust, seamless coating through a chemical reaction, improving waterproofing performance. The thickness of the polyurea waterproof layer 301 is less than the thickness of the epoxy resin layer 202, meaning that the polyurea layer is primarily responsible for initial waterproofing, while the epoxy resin layer 202 provides additional mechanical strength, protection, and abrasion resistance. This design ensures a rational process and synergistic effects between the layers.

[0032] Furthermore, the structural reinforcement layer 4 is located at the bottom of the absorbent layer 505. The structural reinforcement layer 4 includes a steel fiber mortar mixture layer 401, the thickness of which is 0.3 mm, and the thickness of which is greater than the thickness of the waterproof layer.

[0033] The primary purpose of structural reinforcement layer 4 is to enhance the mechanical strength and impact resistance of the flooring. Located at the bottom of absorbent layer 505, it strengthens the structural stability of the entire flooring system, especially in high-load or high-impact applications. Steel fibers, as a reinforcing material, significantly improve the tensile strength, compressive strength, and impact resistance of the composite layer. The introduction of steel fibers alters the stress distribution of the material, improving the toughness of the structural layer. Furthermore, the sand particles in the mortar provide foundation support and structural stability, combining with the steel fibers to form a composite material that possesses both toughness and strength.

[0034] Furthermore, the permeation pore 203 passes through the silver ion antibacterial layer 204, the fiberglass cloth layer 201, and the epoxy resin layer 202 sequentially from top to bottom, with the fiberglass cloth layer 201 attached to the surface of the epoxy resin layer 202.

[0035] The permeable pores 203 are holes that penetrate the entire structure, running sequentially from top to bottom through the silver ion antibacterial layer 204, the fiberglass cloth layer 201, and the epoxy resin layer 202. Their main function is to allow the permeability of gases or liquids, enhancing surface functionality, possibly related to antibacterial or moisture-proof properties. Silver ions possess excellent antibacterial properties; their release effectively inhibits and kills bacteria and other microorganisms. The design of the permeable pores 203 ensures overall antibacterial properties while maintaining the flowability of substances or gases. The addition of fiberglass cloth allows for good adhesion with the epoxy resin, enhancing the structure's strength and durability. The high strength and tensile strength of fiberglass make the entire structure more robust and prevent breakage due to external forces. Epoxy resin, as the bottom layer material, not only provides good adhesion and chemical resistance but also forms a waterproof barrier. The permeable pores 203 penetrate this layer, ensuring the environmental adaptability of the internal materials while maintaining the overall protective properties of the structure.

[0036] Furthermore, the floor base layer 1 is a single-layer structure, and the surface of the floor base layer 1 has a rough surface for the construction of the rigid cement mortar filling layer. The surface of the rigid cement mortar filling layer is also provided with a water-based polyurethane primer layer.

[0037] The base layer 1, serving as the foundation, utilizes a single-layer structure to simplify the construction process while ensuring sufficient strength and stability. This single-layer design reduces material costs and construction complexity. The rough surface of the base layer 1 increases adhesion between the rigid cement mortar filler layer and the base layer. This roughness promotes mechanical interlocking of the filler layers, reducing the possibility of interlayer slippage and thus improving the overall structural stability. The rigid cement mortar filler layer is crucial for providing additional strength and durability. It effectively distributes pressure under load and provides a robust surface. This layer, through its strong bond with the base layer, forms a composite structure with high shear strength. A water-based polyurethane primer layer is applied over the rigid cement mortar filler layer, forming a protective layer. This layer not only enhances the surface's abrasion and chemical resistance but also provides a degree of waterproofing. The water-based polyurethane primer exhibits excellent adhesion, providing a good base for subsequent surface treatments such as topcoats.

[0038] Furthermore, the thickness of the oil-resistant paint layer 501 is 0.2mm-0.3mm.

[0039] Oil-resistant paint coatings are typically composed of a mixture of ingredients, including epoxy resin, polyurethane, and modified additives. These components work together to give the paint coating excellent resistance to oil stains. Adding antibacterial agents to the formulation further enhances the hygienic properties of the paint coating, inhibiting the growth of bacteria and mold. A thickness of 0.2mm is suitable for general low-flow food processing environments, providing basic oil and antibacterial protection, ideal for small restaurant kitchens or low-frequency food preparation areas. A thickness of 0.3mm is suitable for high-flow, high-intensity food processing plants or large catering service facilities, providing stronger protection and ensuring resistance to wear under continuous mechanical impact and chemical erosion.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
