[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] A QPC floor comprises a floor body 1, the total thickness of the floor body 1 is between 2-15 mm, and the floor body 1 comprises a sound-proof layer 11, a base material layer 12, a pattern layer 13, a wear-resistant layer 14 and a surface hardened layer 15 arranged in sequence from bottom to top. The sound-proof layer 11 is made of polystyrene foam board, the base material layer 12 is made of a mixture of PVC powder and stone powder through high-temperature extrusion and pressing, the top surface of the wear-resistant layer 14 is a surface hardened layer 15 composed of PU resin, quartz stone powder and melamine, and the upper surface of the surface hardened layer 15 is roller-coated with a primer. The paint layer and the topcoat layer have good brightness, and are wear-resistant and scratch-resistant. 2 to 6 coatings of different thicknesses are roller-coated between the primer layer and the topcoat layer, making the overall structure softer; the wear-resistant layer 14 uses a PVC transparent film with a thickness between 0.07-1.0 mm, and the thickness of the surface hardening layer 15 is: 0.15-0.7 mm. Multiple groups of floor bodies 1 are connected by mounting parts 2, and the mounting parts 2 include a protrusion 21 and a mounting groove 22. The protrusion 21 and the mounting groove 22 are both "T"-shaped, and the protrusion 21 can be embedded in the inside of the mounting groove 22.

[0028] Referring to Figures 1-3, first, a base material layer 12 made of a mixture of PVC powder and stone powder through high-temperature extrusion and pressing is used as the base material. A silent layer 11 made of PE foam material is added to the bottom of the base material layer 12 to reduce the harm caused by noise to users. A pattern layer 13 is also added, which can be printed according to user preferences. A wear-resistant layer 14 is added on the top of the pattern layer 13 to protect the floor body 1 and improve its wear resistance. Finally, a surface hardening layer 15 composed of PU resin, quartz stone powder and melamine is compounded on the top of the wear-resistant layer 14. PU is polyurethane with good heat insulation, sound insulation, shock resistance and chemical resistance, which improves surface gloss, wear resistance, prevents scratches, prevents cigarette burns, and is antibacterial and anti-fouling. At the same time, in order to facilitate the installation of the floor body 1, a mounting part 2 is provided. When in use, the protrusion 21 on the outside of each floor body 1 is aligned with the mounting groove 22 and clamped to complete the installation, and the installation is more secure.
