[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3A type of stone-plastic flooring with good installation effect includes a body 1 and a protective film 2. The protective film 2 is provided with double-sided adhesive 3 on the top. The bottom of the body 1 has a groove 4, and there are several grooves 4. The internal materials of the body 1 include, in sequence, an anti-slip layer 6, a base layer 7, a flame-retardant fiber layer 8, a silver ion antibacterial layer 9, and a nano hydrophobic wear-resistant layer 10. One side of the anti-slip layer 6 is connected to one side of the base layer 7, the other side of the base layer 7 is connected to one side of the flame-retardant fiber layer 8, the other side of the flame-retardant fiber layer 8 is connected to one side of the silver ion antibacterial layer 9, and the other side of the silver ion antibacterial layer 9 is connected to one side of the nano hydrophobic wear-resistant layer 10.

[0021] In this embodiment, the protective film 2 is bonded and fixed to the bottom of the body 1 by the double-sided adhesive 3, which can completely cover the groove 4 and protrusion 5 at the bottom of the body 1, effectively blocking external dust, sand and other impurities from entering the groove 4. When installation is required, simply peel off the protective film 2. At this time, the double-sided adhesive 3 will peel off synchronously with the protective film 2, avoiding the adhesive residue from affecting the installation effect.

[0022] The specific installation process is as follows: The main body 1 is laid on the pre-constructed cement base surface (flatness error ≤2mm). The bottom groove 4 increases the contact area with the ground through mechanical interlocking (30% higher than the flat structure), which increases the static friction coefficient from 0.5 to 0.8, significantly enhancing the installation stability. At the same time, the anti-slip layer 6 on the surface of the main body 1 adopts a micron-level raised texture design to further improve the surface anti-slip performance, especially in wet environments where the anti-slip effect can be improved by 40%.

[0023] The various functional layers inside the main body 1 work together: the glass fiber flame-retardant layer 8 (oxygen index ≥30%) embedded in the base layer 7 can make the floor fire rating reach B1 level, and can effectively delay the spread of flames when exposed to open flames; the silver ion antibacterial layer 9 achieves a 99% antibacterial rate against Escherichia coli and Staphylococcus aureus by slowly releasing silver ions (release concentration ≤0.01mg / L); the nano hydrophobic wear-resistant layer 10 adopts a silica composite coating (thickness 50-100nm) to form a lotus leaf effect hydrophobic surface (water droplet contact angle ≥110°), and at the same time, the wear resistance exceeds 8000 revolutions, meeting the use needs of densely populated places.

[0024] In this embodiment, to ensure that the protective film 2 completely covers the bottom of the body 1, the size of the protective film 2 is specially designed to perfectly match the body 1. This size fit is reflected in the fact that the length and width of the protective film 2 have an error of ≤0.5mm with the bottom outline of the body 1, which can accurately cover the groove 4 structure at the bottom of the body 1 and avoid the problem of edge exposure caused by size deviation. Through this design, the protective film 2 can effectively block dust, moisture and other impurities from entering the groove 4 at the bottom of the body 1 during transportation and storage, ensuring the cleanliness of the base surface during installation, thereby ensuring that the mechanical interlocking effect between the groove 4 and the ground is not affected by impurities, and further improving the installation stability of the stone plastic floor.

[0025] In this embodiment, to enhance the frictional adhesion between the body 1 and the ground, several protrusions 5 are evenly arranged on the bottom of the body 1. These protrusions 5 have a hemispherical structure (diameter 1.5-2mm, height 0.8-1mm) and are made of the same material as the base layer 7 (PVC + calcium carbonate composite system). They are integrally formed with the body 1 through an extrusion molding process. The protrusions 5 are distributed in a matrix (lateral spacing 10-15mm, longitudinal spacing 8-12mm), forming a three-dimensional frictional structure with the grooves 4.

[0026] Mechanical interlocking mechanism: The protrusion 5 can be embedded in the micropores of the cement base surface, and together with the groove 4, it forms a double anti-slip structure of "protrusion filling + groove interlocking", which increases the contact area by 25%-30% compared with the flat design and increases the static friction coefficient to 0.75-0.8 (about 0.5 for ordinary flat floor).

[0027] Anti-deformation design: The bottom diameter of the protrusion 5 is larger than that of the top, forming an inverted frustum transition (tapered 15°-20°). When subjected to stepping pressure, it can disperse stress and prevent the protrusion from breaking due to long-term pressure, thus ensuring the durability of friction performance.

[0028] In this embodiment, to improve the flame retardant effect, the flame retardant fiber layer 8 is made of glass fiber. The glass fiber (silica content ≥60%) has a melting point of 680-760℃ and an oxygen index ≥30%, making it a flame-retardant material. This allows the floor to achieve the B1 rating specified in GB8624-2012. It is made of alkali-free glass fiber knitted felt with a diameter of 10-15μm, treated with a silane coupling agent, and then hot-pressed together with the PVC base layer. The thickness is 0.2-0.3mm, which ensures both flame retardancy and does not affect the flexibility of the floor (flexural strength ≥45MPa). According to the GB / T2408-2021 vertical burning test, the average burning height of the floor is ≤150mm, the average burning time is ≤30s, the dripping material does not ignite the degreased cotton, and there is no halogen release. The smoke density rating is ≤50, making it suitable for places with high requirements for fire prevention and air quality, such as hospitals and schools.

[0029] In this embodiment, to improve the strength of the double-sided adhesive 3, an organosilicon double-sided adhesive is selected. This double-sided adhesive uses silicone rubber as a base material and has excellent bonding performance and environmental adaptability: its peel strength can reach 8-12 N / cm, and it can form a strong bond on the surface of materials such as metal and PVC. It also has outstanding high and low temperature resistance (operating temperature range -50℃ to 300℃), which can adapt to temperature fluctuations during the transportation, storage and use of the floor. The organosilicon layer also has good weather resistance. After 5000 hours of ultraviolet irradiation, the adhesive retention rate is over 80%, and it is not easy to yellow or become brittle. In addition, the adhesive layer has good compatibility with the protective film 2 and the PVC material at the bottom of the body 1. No adhesive residue will be left when it is removed, ensuring that the bottom of the body 1 is clean during installation, thereby ensuring the friction effect between the groove 4 and the ground. The high strength characteristics of this organosilicon double-sided adhesive can not only reliably cover the bottom of the body 1 during transportation, but also be easily removed during installation, meeting the needs of practical applications.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
