[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0021] As Figure 1 shown, an epoxy grinding stone floor with multiple anti-cracking functions includes an epoxy grinding stone layer 1, a fine anti-cracking mortar leveling layer 2, an anti-cracking leveling layer 3, a cold drawn wire layer 4, and an interface agent 5, which are laid on the floor surface 6 in sequence from top to bottom.

[0022] Among them, the interface agent 5 is located between the floor surface 6 and the cold drawn wire layer 4, enhancing the bonding and adhesion with the reinforced concrete main structure through the interface agent 5, playing the first anti-cracking role, and avoiding the cracking of the finally formed surface layer caused by floating dust and impurities existing on the main structure.

[0023] The cold drawn wire layer 4 is located between the interface agent 5 and the anti-cracking leveling layer 3, mainly enhancing the anti-cracking effect through the wire mesh, playing the second anti-cracking role, preventing cracks from occurring between the main structure layer and the surface decoration layer due to different materials and transmitting to the surface layer to cause structural cracks on the surface layer.

[0024] The anti-cracking leveling layer 3 is located between the cold drawn wire layer 4 and the fine anti-cracking mortar leveling layer 2, mainly leveling the unevenness of the main structure, and secondly enhancing the prevention and control effect on the structural cracks transmitted by the main structure, playing the third anti-cracking role. Generally, a 50mm thick anti-cracking mortar leveling layer (mixed with metal materials) is used, and the actual thickness is set according to site requirements.

[0025] The fine anti-cracking mortar leveling layer 2 is located between the anti-cracking leveling layer 3 and the epoxy grinding stone layer 1. Through this fine anti-cracking mortar leveling layer 2, the precise leveling of the anti-cracking leveling layer 3 is realized, and the anti-cracking effect of the main structure is enhanced in cooperation with the third anti-cracking layer, preparing for the moisture-proof layer of the construction surface layer. Generally, a 20mm thick fine anti-cracking mortar leveling layer is used.

[0026] Between the fine anti-cracking mortar leveling layer 2 and the epoxy grinding stone layer 1, a glass fiber layer, an anti-cracking inhibition film, and a moisture-proof layer are also sequentially arranged from top to bottom.

[0027] The moisture-proof layer is located between the anti-cracking inhibition film and the fine anti-cracking mortar leveling layer 2, mainly playing a moisture-proof role, preventing moisture on the ground from penetrating into the anti-cracking mortar leveling layer due to the moisture in the surface layer during the construction of the moisture-proof surface layer, resulting in quality problems such as moisture return or bulging after the final formation.

[0028] The anti-cracking inhibition film is located between the glass fiber layer and the moisture-proof layer, playing the role of preventing the cracks of the main structure from transmitting to the upper surface layer and causing the upper surface layer to crack, mainly playing the fourth anti-cracking role in preventing the main structure.

[0029] The glass fiber layer is located between the epoxy grinding stone layer 1 and the anti-cracking inhibition film, mainly playing the fifth anti-cracking role in preventing the main structure, further preventing the surface layer from cracking due to the transmission of the main structure cracks to the epoxy grinding stone layer.

[0030] The epoxy grindstone layer 1 is located on the surface of the fiberglass layer and is an important part of this epoxy grindstone floor with multiple crack prevention functions. It is generally made by mixing epoxy resin and pebbles, paving, and grinding. Generally, an epoxy grindstone layer with a thickness of 12 mm is used.

[0031] A curing agent is also sprayed on the surface of the epoxy grindstone layer 1. The curing agent needs to be sprayed three times on the surface of the epoxy grindstone layer 1, mainly to promote the curing effect on the surface of the epoxy grindstone and avoid the extension of the curing time due to the epoxy resin added to the grindstone layer. Especially after the epoxy topcoat construction is completed for 24 hours, there are still problems such as uneven solidification on the surface, where some surfaces have been cured and some places are still sticky, resulting in cracking on the surface of the epoxy grindstone, effectively avoiding the generation of shrinkage cracks, stress cracks, and creep cracks.

[0032] After spraying the curing agent, a two-component polypropylene polyurethane sealing and protective layer also needs to be sprayed twice. Spraying the two-component polypropylene polyurethane mainly plays a role in sealing and protection, enhancing the final waterproof, anti-seepage, and anti-corrosion construction technology on the surface of the epoxy grindstone floor, and extending the service life and cracking resistance of the floor.

[0033] In the above embodiments, the basic principles, main features, and advantages of the present invention are described. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, any modifications and changes made by those skilled in the art that do not depart from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
