Description

Technical Field

[0001] This utility model relates to the field of flooring technology, specifically to a lightweight SPC floor. Background Technology

[0002] Flooring is a building material used for the surface layer of a house floor or roof. It is made of wood or other materials. As an important decorative material for the interior floor of a building, flooring is not only beautiful and practical, but can also meet different usage needs according to different materials and processes. SPC flooring is a type of flooring. Its base layer is a flooring material made of stone powder and polymer resin pressed at high temperature.

[0003] For example, the authorized patent with announcement number CN214739572U (an SPC floor): includes a floor body, which consists of a PVC wear-resistant layer, a PVC color film layer, a PVC substrate layer and a shock-absorbing layer from top to bottom. The PVC wear-resistant layer, the PVC color film layer, the PVC substrate layer and the shock-absorbing layer are bonded together by heating. The shock-absorbing layer is a polyethylene closed-cell foam board. One end of the floor body is integrally connected with a tenon, and the other end of the floor body is provided with a tenon groove. The tenon and the tenon groove are compatible with each other.

[0004] While the aforementioned existing technologies can connect floorboards using a plug-in method, traditional SPC flooring often uses a solid subfloor, resulting in a relatively heavy overall weight. This not only increases transportation and installation costs but also presents certain shortcomings in sound absorption and heat insulation. Therefore, there is an urgent market need to develop a lightweight SPC flooring to help people solve these existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight SPC flooring to solve the problems mentioned in the background art, which are that traditional SPC flooring often uses a solid base layer, resulting in a large overall weight of the flooring. This not only increases transportation and installation costs, but also has certain shortcomings in sound absorption and heat insulation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight SPC flooring, comprising a flooring body, the flooring body comprising a wear-resistant layer, a colored film layer, an upper functional layer, a base layer and a lower functional layer, the wear-resistant layer being disposed above the colored film layer, the colored film layer being disposed above the upper functional layer, the upper functional layer being disposed above the base layer, the base layer being disposed above the lower functional layer, and the base layer being configured as a micro-foamed base layer.

[0007] Preferably, the upper functional layer includes a flame-retardant layer and a waterproof layer, with the flame-retardant layer disposed above the waterproof layer.

[0008] Preferably, the waterproof layer is made of high-density polyethylene material.

[0009] Preferably, the lower functional layer includes a moisture-proof layer, a sound-absorbing layer, and a balancing layer, with the moisture-proof layer disposed above the sound-absorbing layer and the sound-absorbing layer disposed above the balancing layer.

[0010] Preferably, the moisture-proof layer is a waterproof membrane, the sound-absorbing layer is made of cross-linked polyethylene foam, and the balancing layer is made of fiberglass cloth.

[0011] Preferably, the surface of the wear-resistant layer is provided with a UV coating layer.

[0012] Preferably, the front end and one side of the base layer are fixedly installed with insert plates, and the rear end and the other side of the base layer are provided with slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model uses a micro-foamed base layer as the structural layer, which reduces the overall weight of the floor. This not only significantly reduces the cost burden during transportation and installation and improves construction efficiency, but also gives the floor better sound absorption and heat insulation performance. The micro-foaming technology makes tiny bubbles form inside the base layer. These bubbles can isolate sound transmission and reduce noise pollution, while improving the heat insulation capacity of the floor. Thus, the lightweight SPC floor achieves a perfect combination of lightweight and functionality while maintaining high strength and durability, increasing its practicality.

[0015] (2) This utility model sets up an upper functional layer, which includes a flame-retardant layer and a waterproof layer. The flame-retardant layer effectively improves the fire resistance of the SPC floor and increases the safety of the place of use, which is especially important in environments with high fire resistance requirements. The waterproof layer greatly enhances the waterproof performance of the SPC floor, prevents problems such as floor expansion and deformation caused by water penetration, extends the service life of the SPC floor, and reduces maintenance costs caused by water damage.

[0016] (3) This utility model sets up a lower functional layer, which includes a moisture-proof layer, a sound-absorbing layer and a balance layer. The moisture-proof layer effectively blocks the ground moisture from eroding the SPC floor and protects the stability of the SPC floor structure. The sound-absorbing layer further improves the sound insulation effect of the SPC floor and reduces noise interference. The addition of the balance layer enhances the flatness and stability of the SPC floor, prevents the SPC floor from warping due to temperature and humidity changes, and ensures the beauty and durability of the SPC floor.

[0017] (4) By setting a UV coating layer, this utility model improves the wear resistance of the floor surface, enabling SPC flooring to resist daily wear and maintain its gloss and beauty for a long time. At the same time, the UV coating layer also has certain antibacterial and anti-fouling functions, which helps to keep the SPC flooring clean and hygienic and increases its practicality.

[0018] (5) The utility model enables the SPC flooring to be spliced ​​during installation by setting the insert plate and slot, ensuring the flatness and stability of the splicing point of the flooring, avoiding unevenness caused by improper splicing, and increasing practicality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-5 This utility model provides an embodiment of a lightweight SPC flooring, comprising a flooring body 1. The flooring body 1 includes a wear-resistant layer 2, a colored film layer 3, an upper functional layer 4, a base layer 5, and a lower functional layer 6. The wear-resistant layer 2 is disposed above the colored film layer 3, the colored film layer 3 is disposed above the upper functional layer 4, the upper functional layer 4 is disposed above the base layer 5, and the base layer 5 is disposed above the lower functional layer 6. The base layer 5 is a micro-foamed base layer with a density of 1.65±0.05g / cm³. 3 .

[0027] By employing a micro-foamed base layer, with a density of 1.65±0.05 g / cm³, 3 This not only significantly reduces the overall weight of the flooring, effectively lowering the cost burden during transportation and installation and improving construction efficiency, but also significantly improves the sound absorption and heat insulation performance of the flooring. Traditional solid-base flooring often increases installation difficulty and transportation costs due to its excessive weight, while performing only moderately in terms of sound absorption and heat insulation. In contrast, the micro-foamed base layer of lightweight SPC flooring can isolate sound transmission, reduce noise pollution, and enhance the flooring's heat insulation capabilities, thereby improving the functionality and practicality of the flooring.

[0028] Please see Figure 3 The upper functional layer 4 includes a flame retardant layer 7 and a waterproof layer 8. The flame retardant layer 7 is disposed above the waterproof layer 8. The flame retardant layer 7 is made of a mixture of flame retardant, reinforcing agent and stabilizer and is applied to the waterproof layer 8 by coating. The waterproof layer 8 is made of high-density polyethylene material and is applied to the base layer 5 by coating.

[0029] The addition of flame-retardant layer 7 effectively improves the fire resistance rating of SPC flooring and increases the safety of the application environment, which is especially important in environments with high fire protection requirements. The addition of waterproof layer 8 greatly enhances the waterproof performance of SPC flooring, preventing problems such as floor expansion and deformation caused by water penetration, extending the service life of SPC flooring, and reducing maintenance costs caused by water damage.

[0030] Please see Figure 4 The lower functional layer 6 includes a moisture-proof layer 9, a sound-absorbing layer 10, and a balance layer 11. The moisture-proof layer 9 is located above the sound-absorbing layer 10, and the sound-absorbing layer 10 is located above the balance layer 11. The moisture-proof layer 9 is a waterproof membrane. The sound-absorbing layer 10 is made of cross-linked polyethylene foam material. The sound-absorbing layer 10 is applied to the balance layer 11 by coating. The balance layer 11 is made of fiberglass cloth material.

[0031] The moisture-proof layer 9 effectively blocks ground moisture from eroding the SPC flooring and protects the stability of the SPC flooring structure. The sound-insulating layer 10 further enhances the sound insulation effect of the SPC flooring and reduces noise interference. The addition of the balancing layer 11 enhances the flatness and stability of the SPC flooring, prevents the SPC flooring from warping due to changes in temperature and humidity, and ensures the aesthetics and durability of the SPC flooring.

[0032] Please see Figure 2 The surface of the wear-resistant layer 2 is provided with a UV coating layer.

[0033] By adding a UV coating layer, the wear resistance of the floor surface is improved, enabling SPC flooring to resist daily wear and tear and maintain its luster and beauty for a long time. At the same time, the UV coating layer also has certain antibacterial and anti-fouling functions, which helps to keep the SPC flooring clean and hygienic, increasing its practicality.

[0034] Please see Figure 5 The base layer 5 has a fixed plate 501 installed on the front end and one side, and a slot 502 is provided on the rear end and the other side.

[0035] The design of the insert plate 501 and slot 502 enables the SPC flooring to be spliced ​​during installation, ensuring the flatness and stability of the spliced ​​areas and avoiding unevenness caused by improper splicing. This helps to improve the overall aesthetics and user comfort of the SPC flooring.

[0036] Working principle: In use, the flooring body 1 consists of a wear-resistant layer 2, a colored film layer 3, an upper functional layer 4, a base layer 5, and a lower functional layer 6. The base layer 5 is a micro-foamed base layer with a density of 1.65±0.05g / cm³. 3 This design effectively reduces the weight of the flooring, lowers transportation and installation costs, and enhances sound absorption and heat insulation performance. The upper functional layer 4 includes a flame-retardant layer 7 and a waterproof layer 8, which respectively improve the fire resistance and waterproof performance of the flooring and extend its service life. The lower functional layer 6 includes a moisture-proof layer 9, a sound-absorbing layer 10, and a balancing layer 11, which respectively block moisture, improve sound insulation, and enhance the flatness and stability of the flooring. The UV coating layer on the surface of the wear-resistant layer 2 improves wear resistance, antibacterial and stain-resistant functions, and keeps the flooring beautiful and clean. At the same time, the design of the insert plate 501 at the front end and one side of the base layer 5 and the slot 502 at the rear end and the other side ensures the flatness and stability of the flooring during installation.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
