Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial flooring technology, and in particular to a polyurethane epoxy composite flooring. Background Technology
[0002] Currently, polyurethane flooring has a wide range of applications in actual production and daily life. However, in actual use, it has been found that the structural strength of current polyurethane flooring is relatively weaker than that of traditional concrete flooring. As a result, wear and tear are severe during use, and the service life is short. This has greatly affected the use of polyurethane flooring and hindered its promotion and application. Therefore, in response to this situation, there is an urgent need to develop a new type of flooring structure to meet the needs of actual use. Summary of the Invention
[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a polyurethane epoxy composite flooring, which aims to solve the problems of the existing technology.
[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: This application provides a polyurethane epoxy composite flooring, which, from bottom to top, consists of a base layer, an elastic layer, a reinforcing layer, a transition layer, a rubber layer, and a wear-resistant layer; The underlying component mainly includes solvent-free polyurethane, which is formed by uniformly coating the solvent-free polyurethane onto a cement floor or asphalt floor. The elastic layer is a solvent-free, moisture-curing polyurethane elastic layer. The reinforcing layer is composed of a fiber body and a foam body. The fiber body is woven into a mesh structure with several gaps. The gaps in the fiber body are filled with foam body, which is rigid polyurethane foam. The transition layer is an epoxy resin coating. The rubber layer is cast from a rubber elastomer material; The wear-resistant layer mainly consists of waterborne polyurethane.
[0005] To further explain, the thickness of the elastic layer is approximately 6-8 mm, the thickness of the transition layer is 0.5-1 mm, the thickness of the rubber layer is 3-6 mm, and the thickness of the wear-resistant layer is 1.5-2 mm.
[0006] To further explain, the fiber body is selected from one or more of the following: man-made fibers, metal alloy wires, aramid fibers, quartz fibers, glass fibers, basalt fibers, and plant paper fibers.
[0007] To further explain, the polyurethane rigid foam is composed of polyether polyol, isocyanate, filler, coupling agent, flame retardant and additives. The additives are at least one of dispersant, film-forming aid, thickener, defoamer, activator, penetrant, colorant and suspending agent.
[0008] In summary, the advantages of this invention compared to the prior art are as follows: the reinforcing layer provides horizontal bending support to the board through the fiber body, and the foam provides longitudinal compression support to the board, resulting in superior overall mechanical properties of the flooring. Furthermore, the rigid polyurethane foam is cured and shaped after the foaming reaction, thus providing sound and heat insulation. In addition, the water-based polyurethane used on the surface has excellent fire retardancy, slip resistance, and chemical corrosion resistance. By setting a water-based polyurethane wear-resistant layer, the surface hardness of the composite flooring can be increased, its scratch resistance improved, and its durability enhanced.

It should be understood that these embodiments are given merely to enable those skilled in the art to better understand and implement the invention, and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided to make this disclosure more thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art. The terms "embodiment" or "implementation" in this specification may refer to one embodiment or a combination of embodiments or implementations.
[0012] It should be noted that the number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.
[0013] According to one embodiment of the present invention, a polyurethane epoxy composite flooring is provided, comprising, from bottom to top, a bottom layer 1, an elastic layer 2, a reinforcing layer 3, a transition layer 4, a rubber layer 5, and a wear-resistant layer 6.
[0014] The bottom layer component 1 mainly comprises solvent-free polyurethane, which is formed by uniformly coating the solvent-free polyurethane onto a cement floor or asphalt floor.
[0015] The elastic layer 2 is a solvent-free, moisture-curing polyurethane elastic layer 2 with a thickness of approximately 6-8 mm.
[0016] The reinforcing layer 3 is composed of a fiber body and a foam body. The fiber body is selected from one or more of the following: artificial fibers, metal alloy wires, aramid fibers, quartz fibers, glass fibers, basalt fibers, and plant paper fibers. In this embodiment, artificial fibers are selected. The fiber body is woven into a mesh structure with several gaps. The gaps in the fiber body are filled with foam body, which is rigid polyurethane foam. The rigid polyurethane foam is composed of polyether polyol, isocyanate, filler, coupling agent, flame retardant, and additives. The additives are at least one of the following: dispersant, film-forming aid, thickener, defoamer, activator, penetrant, colorant, and suspending agent. In this embodiment, the additive used is a thickener. The rigid polyurethane foam is cured and shaped after the foaming reaction, so it has the effect of sound insulation and heat insulation. In addition, the fiber body provides horizontal bending force support for the board, while the foam body provides longitudinal compression support for the board, making the overall mechanical properties of the floor more excellent.
[0017] The transition layer 4 is an epoxy resin coating with a thickness of 0.5-1mm.
[0018] The rubber layer 5 is cast from a rubber elastomer material, and its thickness is preferably 3-6 mm.
[0019] The wear-resistant layer 6 mainly comprises water-based polyurethane. The thickness of the wear-resistant layer 6 is preferably 1.5-2mm. Water-based polyurethane has excellent fire resistance, anti-slip properties, and chemical corrosion resistance. By setting the water-based polyurethane wear-resistant layer 6, the surface hardness of the composite flooring can be increased, its scratch resistance can be improved, and its durability can be enhanced.
