Description

Technical Field

[0001] This utility model relates to the field of PVC flooring technology, and in particular to a type of PVC flooring. Background Technology

[0002] PVC flooring refers to flooring made of polyvinyl chloride. PVC flooring is made from polyvinyl chloride and its copolymer resin as the main raw materials, with the addition of fillers, plasticizers, stabilizers, colorants and other auxiliary materials. It is produced on a continuous sheet substrate through coating, calendering, extrusion or compression processes.

[0003] PVC flooring is a very popular new type of lightweight floor decoration material in the world today. It is also known as "lightweight flooring". PVC flooring is widely used in various places such as homes, hospitals, schools, office buildings, factories, public places, supermarkets, and commercial spaces.

[0004] Existing PVC flooring, such as the environmentally friendly water-based ink PVC flooring disclosed in the authorization announcement number CN220908995 U published on May 7, 2024, although it discloses a scratch-resistant and stain-resistant layer and a wear-resistant layer, has poor fire resistance and flame retardant properties. In addition, its outer perimeter lacks protection, making it easily damaged during installation or transportation, which in turn affects its normal use.

[0005] Therefore, in this utility model patent application, the applicant has carefully researched a PVC flooring to solve the above-mentioned problems. Utility Model Content

[0006] This utility model addresses the shortcomings of the existing technology by providing a PVC flooring that protects the flooring itself while facilitating seamless splicing of adjacent PVC flooring units from top to bottom. This ease of splicing ensures that the PVC flooring units do not shift in the front-back or left-right directions after splicing, guaranteeing stability and reliability during use. Furthermore, it does not affect the normal use of the flooring unit. Moreover, the PVC flooring possesses high fire resistance and flame retardancy, enriching its performance characteristics.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A PVC flooring includes a PVC flooring body and outer protective layers located on the outer periphery of the PVC flooring body.

[0009] The PVC flooring body includes, from top to bottom, a UV anti-scratch and anti-fouling layer, a wear-resistant layer, a fireproof layer, a flame-retardant layer, a first waterproof layer, a PVC base layer, and a second waterproof layer;

[0010] The wear-resistant layer includes a first wear-resistant layer and a second wear-resistant layer. The first wear-resistant layer is bonded to the upper surface of the second wear-resistant layer. The second wear-resistant layer and the flame-retardant layer are respectively bonded to the upper and lower surfaces of the fireproof layer. The first waterproof layer and the second waterproof layer are respectively coated on the upper and lower surfaces of the PVC base layer.

[0011] The upper surface of the outer protective layer on the left side of the PVC flooring body is recessed into a T-shaped groove, which extends to the outer side of the outer protective layer. The right side of the outer protective layer on the right side of the PVC flooring body is provided with a T-shaped protrusion for fitting another PVC flooring.

[0012] When adjacent PVC floorboards are spliced ​​together, one of their T-shaped protrusions fits into the other T-shaped groove.

[0013] As a preferred embodiment, the PVC flooring body further includes a moisture-proof layer and an antibacterial layer;

[0014] The flame-retardant layer is located above the moisture-proof layer, the moisture-proof layer is bonded to the upper surface of the antibacterial layer, and the antibacterial layer is bonded to the upper surface of the first waterproof layer.

[0015] As a preferred embodiment, the outer protective layer includes a wear-resistant and anti-slip layer and a thermal insulation layer disposed inside the wear-resistant and anti-slip layer. The thermal insulation layer is also bonded and connected to the wear-resistant layer, fireproof layer, flame-retardant layer, moisture-proof layer, antibacterial layer, first waterproof layer, PVC base layer, and second waterproof layer.

[0016] As a preferred embodiment, the PVC flooring body further includes a first elastic layer and a second elastic layer, wherein the first elastic layer is located between the flame-retardant layer and the second elastic layer, and the second elastic layer is disposed on the upper surface of the moisture-proof layer.

[0017] As a preferred embodiment, the lower end face of the first elastic layer is provided with a plurality of first protrusions arranged at intervals facing the second elastic layer, and a first groove is formed between adjacent first protrusions;

[0018] The upper surface of the second elastic layer is recessed with several second grooves arranged at intervals and adapted to the first protrusions. The several second grooves divide the upper surface of the second elastic layer into several second protrusions, and the several second protrusions are adapted to the several first grooves one by one.

[0019] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, it mainly protects the flooring body by setting an outer protective layer on its outer periphery. Simultaneously, the T-shaped protrusions and grooves on the outer protective layer facilitate the splicing of adjacent PVC flooring units from top to bottom, making splicing convenient. This ensures that the PVC flooring units will not shift in the front-back, left-right, or right directions after splicing, guaranteeing the stability and reliability of the PVC flooring during use. Furthermore, the T-shaped protrusions are formed on the outer protective layer and will not affect the normal use of the flooring unit. Moreover, the combination of a UV anti-scratch and stain-resistant layer, a wear-resistant layer, a fire-retardant layer, a flame-retardant layer, a first waterproof layer, a PVC base layer, and a second waterproof layer gives the PVC flooring high fire resistance and flame retardancy, enriching its performance.

[0020] Secondly, by using a moisture-proof layer, an antibacterial layer, a first elastic layer, and a second elastic layer, the moisture resistance, antibacterial properties, and elasticity of PVC flooring are improved, further enriching the performance of PVC flooring and extending its service life.

[0021] Furthermore, the outer protective layer formed by the wear-resistant and anti-slip layer and the thermal insulation layer gives PVC flooring good wear resistance, anti-slip properties, and thermal insulation, further enriching the performance of PVC flooring and extending its service life.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 and Figure 2 As shown, a PVC floor includes a PVC floor body 10 and an outer protective layer 20 located on the outer periphery of the PVC floor body 10.

[0039] The PVC floor body 10 includes a moisture-proof layer 11, an antibacterial layer 12, a first elastic layer 13, a second elastic layer 14, and, from top to bottom, a UV anti-scratch and anti-fouling layer 101, a wear-resistant layer 102, a fireproof layer 103, a flame-retardant layer 104, a first waterproof layer 105, a PVC base layer 106, and a second waterproof layer 107.

[0040] The wear-resistant layer 102 includes a first wear-resistant layer 1021 and a second wear-resistant layer 1022. The first wear-resistant layer 1021 is bonded to the upper surface of the second wear-resistant layer 1022. The second wear-resistant layer 1022 and the flame-retardant layer 104 are respectively bonded to the upper and lower surfaces of the fireproof layer 103. When the first wear-resistant layer 1021 is worn, it can still be used through the second wear-resistant layer 1022, thus improving the overall wear resistance of the PVC flooring. In this embodiment, both the first wear-resistant layer 1021 and the second wear-resistant layer 1022 are made of polyvinyl chloride.

[0041] The first elastic layer 13 is located between the flame-retardant layer 104 and the second elastic layer 14, and the second elastic layer 14 is disposed on the upper surface of the moisture-proof layer 11. In this embodiment, both the first elastic layer 13 and the second elastic layer 14 are made of thermoplastic elastic material, increasing the elastic cushioning capacity of the PVC base layer 106. When someone walks on it, it can provide cushioning protection for the PVC base layer 106.

[0042] The lower end face of the first elastic layer 13 is provided with a plurality of first protrusions arranged at intervals facing the second elastic layer 14, and a first groove is formed between adjacent first protrusions;

[0043] The upper surface of the second elastic layer 14 is recessed with a number of second grooves arranged at intervals and adapted to the first protrusions, facing the first elastic layer 13. The number of second grooves divides the upper surface of the second elastic layer 14 into a number of second protrusions, and the number of second protrusions corresponds to and is adapted to the number of first grooves.

[0044] The first waterproof layer 105 and the second waterproof layer 107 are respectively coated on the upper and lower surfaces of the PVC base layer 106. In this embodiment, both the first waterproof layer 105 and the second waterproof layer 107 are polyurethane waterproof coatings, which do not release formaldehyde and have very low VOC content, so they will not cause harm to the human body and are more environmentally friendly.

[0045] The flame retardant layer 104 is located above the moisture-proof layer 11. In this embodiment, the flame retardant layer 104 is made of neoprene rubber.

[0046] The moisture-proof layer 11 is bonded to the upper surface of the antibacterial layer 12. In this embodiment, the moisture-proof layer 11 is made of PVC board. By setting the moisture-proof layer 11, the moisture-proof effect of the bottom of the PVC floor is improved, preventing moisture from the bottom from spreading upward through the floor.

[0047] The antibacterial layer 12 is adhered to the upper surface of the first waterproof layer 105. In this embodiment, the antibacterial layer 12 is an antibacterial plastic layer. Antibacterial plastic is a type of plastic that inhibits or kills bacteria, molds, fungi, algae, and even viruses contaminated on plastic in the environment. It maintains its own cleanliness by inhibiting the reproduction of microorganisms, thereby protecting the PVC base layer 106.

[0048] The outer protective layer 20 can improve the performance of the PVC flooring. The outer protective layer 20 includes a wear-resistant and anti-slip layer 21 and a heat insulation layer 22 disposed inside the wear-resistant and anti-slip layer 21. The heat insulation layer 22 is also bonded to the wear-resistant layer 102, the fireproof layer 103, the flame-retardant layer 104, the moisture-proof layer 11, the antibacterial layer 12, the first waterproof layer 105, the PVC base layer 106, and the second waterproof layer 107.

[0049] A T-shaped groove 32 is recessed downwards on the upper surface of the outer protective layer 20 on the left side of the PVC flooring body, and the T-shaped groove 32 extends to the outer side surface of the outer protective layer 20. Preferably, the T-shaped groove 32 is formed on the wear-resistant and anti-slip layer 21 and the thermal insulation layer 22.

[0050] The outer protective layer 20 on the right side of the PVC floor body has a T-shaped protrusion 31 for fitting another PVC floor; the T-shaped protrusion 31 is formed on the wear-resistant and anti-slip layer 21.

[0051] When adjacent PVC floorboards are spliced ​​together, one T-shaped protrusion 31 fits into another T-shaped groove 32.

[0052] The key design feature of this utility model lies in its outer protective layer, which protects the flooring body. Simultaneously, the T-shaped protrusions and grooves on the outer protective layer facilitate the seamless splicing of adjacent PVC flooring units from top to bottom. This ensures that the PVC flooring units do not shift in the front-back or left-right directions after splicing, guaranteeing their stability and reliability during use. Furthermore, the T-shaped protrusions are formed on the outer protective layer and do not affect the normal use of the flooring unit. Moreover, the combination of a UV-resistant and stain-resistant layer, a wear-resistant layer, a fire-retardant layer, a flame-retardant layer, a first waterproof layer, a PVC base layer, and a second waterproof layer gives the PVC flooring high fire resistance and flame retardancy, enriching its performance characteristics.

[0053] Secondly, by using a moisture-proof layer, an antibacterial layer, a first elastic layer, and a second elastic layer, the moisture resistance, antibacterial properties, and elasticity of PVC flooring are improved, further enriching the performance of PVC flooring and extending its service life.

[0054] Furthermore, the outer protective layer formed by the wear-resistant and anti-slip layer and the thermal insulation layer gives PVC flooring good wear resistance, anti-slip properties, and thermal insulation, further enriching the performance of PVC flooring and extending its service life.

[0055] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
