Before pressing the composite floor body, the core board is placed on the upper end of the bottom board, and the A connecting block and B connecting block are inserted into the A connecting groove and the B connecting groove and clamped. Then, the polyurethane elastomer is filled in the gaps on the left and right of the joints, and then the panel is pressed on the upper end of the core board, and then the whole is pressed. No additional glue is required between the core board and the bottom board, which is more environmentally friendly and harmless. At the same time, the connection can be made more stable. At the same time, the polyurethane elastomer has excellent elasticity and recovery properties, can maintain stable elasticity and shape for a long time, increase the stability of the floor, and is not easy to deform. Filling the gaps can make the entire floor more comfortable to walk on.

[0015] (3) In the utility model, a melamine moisture-proof layer is provided at the lower end of the bottom plate, so that the floor can be directly laid on the cement floor and can prevent the floor from being damp. A certain proportion of moisture-proof particles are added to the melamine moisture-proof layer, and the degree of expansion of the floor due to moisture is greatly reduced, so that it has excellent moisture-proof performance. There is no need to lay a moisture-proof film on the cement floor before laying, which reduces the overall laying process. The floor can be laid directly on the cement floor. The overall laying process is simple and efficient, and the laying speed is increased.

[0016] In summary, the floor has the advantages of increasing the stability of the floor, not being easily deformed, increasing the walking feel of the floor, and having a simple and efficient laying process, and is particularly suitable for the field of floor technology.

[0023] like Figures 1 to 3 As shown, the utility model is an environmentally friendly formaldehyde-free composite floor, which is characterized by:

[0024] Furthermore, an environmentally friendly formaldehyde-free composite floor is characterized in that it includes a composite floor body 1, a panel 2 is provided at the upper end of the composite floor body 1, a core board 3 is provided at the lower end of the panel 2, A connecting blocks 31 are evenly provided at the lower end of the core board 3, A connecting grooves 32 are provided at the left and right ends of the A connecting blocks 31, a bottom plate 4 is provided at the lower end of the core board 3, B connecting blocks 41 are evenly provided at the upper end of the bottom plate 4, and B connecting grooves 42 are provided at the left and right ends of the B connecting blocks 41.

[0025] Furthermore, the A connection blocks 31 and the A connection grooves 32 are alternately distributed, and the B connection blocks 41 and the B connection grooves 42 are alternately distributed, so that the distribution is more uniform and the stability is increased during connection.

[0026] Furthermore, the size and position of the A connection block 31 and the B connection groove 42 are matched, and the size and position of the B connection block 41 and the A connection groove 32 are matched, so that the connection between the interior of the floor is more stable.

[0027] Furthermore, a vacuum titanium-plated nano-coating is provided on the upper end of the panel 2, so that a uniform, dense, and extremely wear-resistant coating is produced on the surface of the composite floor body 1, and the surface maintains its original performance and wood grain, thereby greatly increasing the service life of the floor.

[0028] Furthermore, a gap is provided on the left and right sides of the connection between the A connecting block 31 and the B connecting block 41, and a polyurethane elastomer 5 is provided in the gap. The polyurethane elastomer 5 has excellent elasticity and recovery properties, can maintain stable elasticity and shape for a long time, increase the stability of the composite floor body 1, and is not easy to deform. Filling the gap can make the entire floor feel more comfortable to step on.

[0029] Furthermore, a melamine moisture-proof layer 43 is provided at the lower end of the base plate 4, so that it has excellent moisture-proof performance. There is no need to lay a moisture-proof film on the cement board before laying, which reduces the overall laying process. It can be laid directly on the cement floor. The overall laying process is simple and efficient, which increases the laying speed.

[0030] Working process: first, before pressing the composite floor body 1, place the core board 3 on the upper end of the base board 4, and the A connection block 31 and the B connection block 41 will be stuck in the A connection groove 32 and the B connection groove 42 and clamped, then fill the polyurethane elastomer 5 in the gaps on the left and right of the joint, and then press the panel 2 on the upper end of the core board 3, and then press the whole thing. No additional glue is required between the core board 3 and the base board 4, which is more environmentally friendly and harmless, and can make the connection more stable. At the same time, the polyurethane elastomer 5 has excellent elasticity and recovery properties, can maintain stable elasticity and shape for a long time, increase the stability of the floor, and is not easy to deform. Filling the gap can make the entire floor feel more comfortable to step on, and then press the composite floor body 1. After pressing, the surface of the surface layer 2 is uniformly coated with a vacuum titanium-plated nano-coating to produce a uniform, dense, and extremely wear-resistant coating on the surface of the composite floor body 1, which can make the floor surface maintain its original performance and wood grain, greatly increasing the service life of the floor.

[0031] Secondly, the melamine moisture-proof layer 43 at the lower end of the base plate 4 can allow the composite floor body 1 to be directly laid on the cement floor and can also prevent the composite floor body 1 from being damp. A certain proportion of moisture-proof particles is added to the melamine moisture-proof layer 43 to reduce the degree of its expansion due to moisture, and it has excellent moisture-proof performance. There is no need to lay a moisture-proof film on the cement floor before laying, which reduces the overall laying process and can be directly laid on the cement floor. The overall laying process is simple and efficient, which increases the laying speed.
