Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0041] This utility model provides an overall structural diagram of an embodiment of polyurea flooring, including:

[0042] Please see Figures 1-6The polyurea flooring of this embodiment includes: a surface layer 1 and a reinforcing layer 2. The reinforcing layer 2 is bonded to the bottom of the surface layer 1 and can improve the interlayer shear resistance of the polyurea flooring.

[0043] Buffer layer 3 is bonded to the bottom of reinforcement layer 2. Buffer layer 3 can relieve the pressure on polyurea flooring.

[0044] Base layer 4 is bonded to the bottom of buffer layer 3;

[0045] Anti-slip protrusion 110 is bonded to the top of surface layer 1;

[0046] The anti-crack groove 120 is formed at the top edge of the surface layer 1. The anti-crack groove 120 can prevent the surface layer 1 from cracking due to temperature changes.

[0047] Next, in order to prevent slipping, specifically, the upper end of the anti-slip protrusion 110 is provided with an anti-slip groove 111. The anti-slip groove 111 can further improve the anti-slip performance of the anti-slip protrusion 110. The anti-slip protrusion 110 is bonded to the surface layer 1 with polyurea adhesive so that the worn anti-slip protrusion 110 can be replaced more easily.

[0048] Meanwhile, in order to prevent cracking, the crack-resistant groove 120 is filled with elastic polyurea sealant to reduce the degree of thermal expansion and contraction of the surface layer 1 when the temperature changes.

[0049] Furthermore, to enhance shear resistance, specifically, the reinforcing layer 2 includes a groove a21 formed inside the reinforcing layer 2. A fiberboard 22 is tenon-and-mortise connected within the groove a21. The fiberboard 22 includes a glass fiber corrugated board with the corrugation direction being the same as the main load direction, thereby improving the shear resistance of the polyurea flooring in that direction.

[0050] It is worth noting that, in order to improve elasticity, specifically, the buffer layer 3 has a groove b31 inside, and an elastic column 32 is connected in the groove b31 by tenon and tenon. The upper end of the elastic column 32 has a cross groove 33. The rubber column is made of nitrile rubber. The cross groove 33 can enhance the wrapping with the polyurea coating. Under local impact, the elastic column 32 absorbs energy through compression deformation, avoiding direct cracking of the polyurea floor.

[0051] Finally, for support, specifically, the base layer 4 includes: trapezoidal toothed groove 41, which is formed at the upper end of the base layer 4 and at the connection between the base layer 4 and the buffer layer 3. After the polyurea coating in the buffer layer 3 is cured, it will be embedded in the toothed groove to form a "mortise and tenon joint".

[0052] The wire mesh 42 includes a hot-dip galvanized steel mesh. The surface of the wire mesh 42 is coated with a silane coupling agent, which can enhance the chemical adhesion with the polyurea coating, thereby improving the chemical adhesion with the base layer 4, dispersing the stress of the base layer 4, and inhibiting crack propagation.

[0053] Combination Figures 1-6 The specific application process of a polyurea flooring according to this embodiment is as follows:

[0054] 1: According to actual use, when external force is applied to the polyurea floor, the anti-slip bumps 110 and anti-slip grooves 111 improve the anti-slip effect and prevent damage from external objects. The anti-slip bumps 110 diffuse the stress received to the surface layer 1, and the surface layer 1 transmits the stress to the reinforcing layer 2 and the buffer layer 3. The elastic columns 32 in the buffer layer 3 deform under the force, thus reducing the impact on the polyurea floor.

[0055] 2: The stress on the buffer layer 3 is transmitted to the base layer 4. The steel wire network 42 in the base layer 4 distributes the stress evenly to all parts of the base layer 4, reducing the damage of stress to the polyurea floor.

[0056] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
