Description

Technical Field

[0001] This utility model relates to the field of flat coating flooring technology, specifically a multi-layer composite wear-resistant epoxy flat coating flooring. Background Technology

[0002] Epoxy flooring, also known as epoxy flooring, is a type of flooring made by mixing epoxy resin as the main material with curing agents, diluents, solvents, dispersants, defoamers, and certain fillers. It is applied on-site using specific flooring construction techniques. Epoxy flooring initially served functional purposes such as corrosion resistance, wear resistance, and slip resistance, and has evolved into general-purpose industrial flooring. In addition to meeting functional requirements, it also offers excellent decorative effects. Building on its widespread application in industrial flooring, and with the continuous improvement of people's living standards, it is now being promoted and applied in home decoration.

This invention solves the problems of existing flooring having poor aesthetics, failing to meet the practical needs of some users, and exhibiting severe surface wear after a period of use, making it difficult to meet usage requirements.

[0004] However, this utility model has the following problems in actual use:

[0005] Existing epoxy flat coating flooring typically consists of only two to three layers, generally comprising a primer, putty, and a regular topcoat. Its structure is relatively simple, resulting in lower performance, poor wear resistance, and easy wear. Although the initial cost is low, frequent replacement is required, increasing labor costs. Furthermore, due to its simple structure, existing epoxy flat coating flooring has poor impact resistance. For harsh industrial or logistics environments requiring heavy loads, high wear, and impacts, traditional epoxy flat coating flooring has a short lifespan, further increasing maintenance costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 4 This utility model embodiment provides a multi-layer composite wear-resistant epoxy flat coating floor. This multi-layer composite wear-resistant epoxy flat coating floor is applied to harsh industrial or logistics environments that bear heavy loads, high wear, and impacts. In this embodiment, the structure of the multi-layer composite wear-resistant epoxy flat coating floor is improved, giving it the advantages of high wear resistance and structural performance. Specifically, this multi-layer composite wear-resistant epoxy flat coating floor is suitable for industrial scenarios with high degrees of ground wear. Therefore, as a preferred solution in this embodiment, the epoxy flat coating floor is specifically a multi-layer composite wear-resistant epoxy flat coating floor, capable of withstanding industrial scenarios with high impact.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-layer composite wear-resistant epoxy flat coating floor, which is mainly used in harsh industrial or logistics environments that bear heavy loads, high wear and impact.

[0029] The system includes a base layer 8, with a high-penetration epoxy primer 7 for reinforcement fixedly connected to the top of the base layer 8, a wear-resistant core layer 6 for pressure resistance fixedly connected to the top of the high-penetration epoxy primer 7, an epoxy putty sealing layer 5 for filling gaps fixedly connected to the top of the wear-resistant core layer 6, a thermal insulation layer 4 for cold and heat insulation fixedly connected to the top of the epoxy putty sealing layer 5, and a waterproof layer 3 for waterproofing fixedly connected to the top of the thermal insulation layer 4.

[0030] In this embodiment, the base layer 8, high-penetration epoxy primer 7, wear-resistant core layer 6, epoxy putty sealing layer 5, insulation layer 4, and waterproof layer 3 are arranged in a coordinated manner. The base layer 8 serves to support the adhesion of other coatings and provides a foundation for coating adhesion. The high-penetration epoxy primer 7, which uses epoxy resin as a solvent, penetrates and strengthens the substrate, seals the substrate pores to improve adhesion. The high-penetration epoxy primer 7 uses polyamide with good toughness as a curing agent, which can further strengthen the substrate. The wear-resistant core layer 6 provides resistance to pressure, impact, and heavy loads, and can withstand high mechanical wear. The epoxy putty sealing layer 5 seals the pores of the mortar layer, providing a smooth and delicate substrate to enhance the adhesion of the topcoat. The waterproof layer 3 provides waterproofing and moisture protection, preventing water vapor from eroding the floor and damaging its wear resistance. The insulation layer 4 provides insulation.

[0031] In the above embodiments, as a preferred option, the top of the waterproof layer 3 is fixedly connected to an epoxy topcoat 2 for wear resistance, and the top of the epoxy topcoat 2 is fixedly connected to an antistatic layer 1. The epoxy topcoat 2 penetrates deep into the capillaries of the substrate, sealing and reinforcing it. The epoxy topcoat 2 is made of a low-viscosity and high-penetration solvent-free or solvent-based epoxy resin primer. An active diluent is also used to reduce viscosity and increase penetration depth. At the same time, a wetting and dispersing agent is used to improve the wetting and penetration ability of the concrete micropores. The antistatic layer 1 provides antistatic protection, especially in winter when the air is dry and static electricity is easily generated. Antistatic protection is essential for environments that require strict control of static electricity generation.

[0032] In the above embodiments, as a preferred option, a wire mesh 9 is provided at the top of the antistatic layer 1, and a primer layer 10 is fixedly connected to the top of the wire mesh 9. The wire mesh 9 serves to reinforce the floor surface and further prevent wear and tear on the floor. The primer layer 10 serves to fix the wire mesh 9 and also prevents the wire mesh 9 from being directly exposed, which would be unsightly.

[0033] In the above embodiments, as a preferred option, a decorative top layer 11 is fixedly connected to the top of the primer layer 10. The top layer 11 is made by applying two coats of topcoat by roller brushing. The top layer 11 serves a decorative purpose, making the floor cleaner and more beautiful. The top layer 11 is made by applying the topcoat by roller brushing twice, which allows the fabric to adhere more firmly to the top of the primer layer 10.

[0034] In the above embodiments, as a preferred option, the high-penetration epoxy primer 7 uses epoxy resin as a penetrant, polyamide as a curing agent, and xylene as a diluent. Through the combined action of epoxy resin, polyamide, and xylene, the floor can be sealed and reinforced.

[0035] In the above embodiments, as a preferred option, the wear-resistant core layer 6 uses wear-resistant aggregate as the core material for wear resistance. The wear-resistant core layer 6 adopts a scientific resin-aggregate ratio to ensure complete encapsulation of the aggregate. Through the function of the wear-resistant aggregate, it can provide the main wear resistance and compressive strength. The type of wear-resistant aggregate can be selected according to the applicable scenario of the floor, so as to achieve better wear resistance effect.

[0036] In the above embodiments, as a preferred option, the epoxy putty sealing layer 5 uses ultrafine powder as filler to improve hardness, and the epoxy putty sealing layer 5 uses toughening agent and defoamer as additives. The epoxy putty sealing layer 5 improves the adhesion of the primer layer 10.

[0037] In the above embodiments, as a preferred option, the primer layer 10 is made by applying two coats of primer by roller brush, and the thickness of the primer layer 10 is one millimeter. The primer layer 10 serves an aesthetic purpose, while also improving surface durability, reducing the coefficient of friction, and assisting in preventing scratches.

[0038] In this invention, the working steps of the device are as follows:

[0039] 1. First, before applying the coating to the floor, the workers need to grind the base layer 8. Since the base layer 8 is the adhesive matrix that makes up all the coatings, it determines the chemical stability, adhesion, toughness and final strength of the floor. Therefore, it is necessary to ensure that the grinding degree of the base layer 8 meets the standards for applying the coating, and the base layer 8 also needs to be cleaned.

[0040] 2. Next, the high-penetration epoxy primer layer 7, the wear-resistant core layer 6, and the epoxy putty sealing layer 5 are prepared. The high-penetration epoxy primer layer 7 uses a low-viscosity, high-penetration solvent-free or solvent-based epoxy resin primer as the main material, and active diluents and wetting and dispersing agents as key additives to penetrate deep into the capillaries of the substrate and seal and reinforce it. The wear-resistant core layer 6 uses epoxy resin, curing agent, and high-hardness wear-resistant aggregate as the main materials. When preparing it, attention should be paid to the ratio of resin to aggregate, which should be adjusted according to the aggregate gradation and the required mortar consistency. The higher the proportion of aggregate, the better the wear resistance and the lower the cost, but the higher the requirements for workability and resin adhesion. Next is the preparation of the epoxy putty sealing layer 5. The epoxy putty sealing layer 5 uses solvent-free epoxy resin, ultrafine filler, and curing agent as the main materials, and is supplemented with toughening agents, defoamers, and other key additives to seal pores and level the surface, providing a fine and dense base surface to enhance the adhesion of the topcoat.

[0041] 3. After the high-penetration epoxy primer 7, wear-resistant core layer 6 and epoxy putty sealing layer 5 are completed, the high-penetration epoxy primer 7, wear-resistant core layer 6 and epoxy putty sealing layer 5 are laid. First, the high-penetration epoxy primer 7 is laid, then the wear-resistant core layer 6 is laid, and finally the epoxy putty sealing layer 5 is laid.

[0042] 4. Finally, lay the insulation layer 4, waterproof layer 3, and epoxy topcoat 2. After laying the epoxy topcoat 2, place a layer of wire mesh 9 on the epoxy topcoat 2 to further resist impact and wear. After completion, apply primer to the wire mesh 9 and brush it twice to form the primer layer 10. Then apply the topcoat to form the surface layer 11, making the floor more beautiful and wear-resistant.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
