Technical Field

[0001] The invention relates to the technical field of sports floors, in particular to a closed honeycomb foaming layer structure of a PVC sports floor. Background Art

[0002] PVC sports floor is a kind of sports floor developed for sports venues using polyvinyl chloride materials. Specifically, it is made of polyvinyl chloride and its copolymer resin as the main raw materials, and is added with fillers, plasticizers, stabilizers, colorants and other auxiliary materials. It is produced on a sheet-like continuous substrate through a coating process or by calendering, extrusion or extrusion. It is generally made of a multi-layer structure, generally with a wear-resistant layer (including UV treatment), a glass fiber layer, an elastic foam layer, a base layer, etc. PVC sports floor is widely used. The Olympic Games and other international competitions all specify the use of PVC sports flooring, which shows that the market prospect of this PVC sports floor is very broad.

[0003] PVC flooring is low in price, high in grade, moisture-proof, environmentally friendly and flame-retardant, but ordinary PVC flooring has poor wear resistance and short service life; rubber flooring is environmentally friendly, flame-retardant, wear-resistant, elastic, aging-resistant and non-slip. There are a few products in the elastic sports flooring market that use a composite structure of environmentally friendly PVC flooring and environmentally friendly rubber flooring. Sports flooring has been widely used in various indoor and outdoor places, such as high-end kindergartens, swimming pools, gyms, badminton halls, basketball halls and dance rooms, etc., but the previous sports floors were mostly seamlessly connected to the ground. Although they had good stability, they posed great safety hazards. The vibration reduction performance of the foaming layer was poor. When the impact force was large, the vibration reduction effect was difficult to meet the use requirements, which was easy to cause damage to the user, which was not conducive to the user's safety and could not meet the needs of today's market. Due to the above problems. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1The closed honeycomb foam layer structure of the PVC sports floor includes an upper PVC wear-resistant layer 1, a lower PVC wear-resistant layer 2 and a fiber reinforcement layer 3. The upper PVC wear-resistant layer 1 and the lower PVC wear-resistant layer 2 are polymer materials prepared from polyvinyl chloride resin, which are non-flammable, high-strength, resistant to climate changes, and have excellent geometric stability, and are very resistant. The upper PVC wear-resistant layer 1 and the lower PVC wear-resistant layer 2 are located on the outside of the sports floor and need to have strong wear-resistant functions. One side of the fiber reinforcement layer 3 is covered on the surface of the lower PVC wear-resistant layer 2, and the upper PVC wear-resistant layer 1 is fixed on the other side of the fiber reinforcement layer 3, and a foam layer 4 and a honeycomb support layer 5 are fixed at the bottom of the lower PVC wear-resistant layer 2, and the foam layer 4 is sealed and coated on the outside of the honeycomb support layer 5.

[0027] See also Figure 2-Figure 3 The foaming layer 4 includes a core layer 41, an upper supporting layer 42 and a lower supporting layer 43. The upper supporting layer 42 and the lower supporting layer 43 fix the honeycomb supporting layer 5. The upper supporting layer 42 and the lower supporting layer 43 are made of UPVC polymer material. The UPVC polymer material uses polyvinyl chloride resin as a carrier and has good softness to overcome the shortcomings of plastic brittleness in the past. The upper supporting layer 42 and the lower supporting layer 43 are filled with the core layer 41, and the elasticity of the core layer 41 needs to be fed back through the upper supporting layer 42 and the lower supporting layer 43. If a structure with stronger strength is used, the elasticity of the core layer 41 cannot be fed back. The core layer 41 is made of carbon fiber polymer foam material. The cellulose polymer foaming technology is a technology that can prepare materials with unique dense surface and foaming structure. Under the premise of ensuring the basic performance of the material, the weight of the product can be significantly reduced. The sports floor is an elastic floor material. The rebound and shock absorption brought by the core layer 41 can prevent users who exercise on it from being injured. The pores of the core layer 41 need to be small and evenly arranged to improve its rebound performance. The core layer 41 is filled between the upper support layer 42 and the lower support layer 43. A hexagonal groove for inserting the upper hexagonal tube 51 is processed on one side of the upper support layer 42. The surface of the lower support layer 43 and the bottom seal 53 are fixed to each other and covered with the honeycomb support layer 5.

[0028] See also Figure 4-Figure 5The honeycomb support layer 5 includes an upper hexagonal tube 51, a lower hexagonal tube 52 and a bottom seal 53. The upper hexagonal tube 51 is open at both ends and a cannula is fixed at one end. The bottom opening of the lower hexagonal tube 52 is sealed by the bottom seal 53. The bottom seal 53 fixes the bottom of the lower hexagonal tube 52, and the top opening is inserted with a cannula to form a single hexagonal support structure. A group of upper hexagonal tubes 51 and lower hexagonal tubes 52 are fixed to form a hexagonal support structure. No less than one hexagonal support structure is fixed to each other to form a honeycomb support layer 5. The honeycomb structure is used to improve its overall stability and firmness. Complementary blocks and slots are also connected to the outer wall of the lower hexagonal tube 52. The hexagonal support structures are connected and spliced ​​to each other through the blocks and slots to form an integral honeycomb support layer 5. During installation, only adjacent blocks and slots need to be connected. The installation is completed by inserting the grooves into each other, and the installation is simple. The side walls of the upper hexagonal tube 51 and the lower hexagonal tube 52 are provided with through holes with a diameter of not less than 1 cm. The core layer 41 is coated on the outside of the honeycomb support layer 5, and fills the inside of the hexagonal support structure through the through holes, and fills the space between the upper support layer 42 and the lower support layer 43. The inside of the hexagonal support structure is filled through the core layer 41, and the space between the upper support layer 42 and the lower support layer 43 is also filled. The upper hexagonal tube 51 and the lower hexagonal tube 52 are connected and their movement is only in the vertical direction, which makes the connection between the upper support layer 42 and the lower support layer 43 more firmly, and cooperates with the core layer 41 to change the gravity pressed on the upper support layer 42 at different angles into the vertical direction, and its rebound direction is upward, so that the elastic force fed back by the entire foaming layer 4 is more obvious.

[0029] Embodiment 2:

[0030] See also Figure 6 The honeycomb support layer 5 is distributed in a matrix, and the matrix rows and columns are adjustable. By changing the matrix state of the honeycomb support layer 5, it can be designed to be an entire honeycomb, or a single row and a single column according to the needs. It is flexible in changing, so that the overall usage degree is high. In the more commonly used sports floor area, the honeycomb support layer 5 is dense as a whole, so that the vertical upward elastic angle of the local area has the processing strength. In the less used sports floor area, the honeycomb support layer 5 is sparse as a whole, so that the elastic force of the local area is the direct feedback of the foaming layer 4.

[0031] Embodiment three:

[0032] The upper hexagonal tube 51 and the lower hexagonal tube 52 are also made of UPVC polymer material. The upper hexagonal tube 51 and the lower hexagonal tube 52 are made of elastic UPVC polymer material with high flexibility and can produce a certain deformation. When the connected upper supporting layer 42 is pressed down by pressure, the direction of its rebound force is decomposed according to the angle of the downward pressure, which can produce an elastic force that is always upward different from the first embodiment. The feedback rebound force is opposite to the force acting on the upper supporting layer 42. In addition, the high flexibility of the upper hexagonal tube 51 and the lower hexagonal tube 52 allows the entire floor to have rebound at different angles. The gravity of the core layer 41 pressing on the upper supporting layer 42 at different angles can be changed to a vertical direction, and its rebound direction is upward, making the elastic force feedback of the entire foaming layer 4 more obvious.

[0033] In summary: the PVC sports floor has a closed honeycomb foam layer structure, and the upper support layer 42 and the lower support layer 43 are made of UPVC polymer material. The UPVC polymer material uses polyvinyl chloride resin as a carrier, and has good softness and overcomes the shortcomings of plastic brittleness in the past. The upper support layer 42 and the lower support layer 43 are filled with the core layer 41. If a stronger structure is used, the elasticity of the core layer 41 cannot be fed back. The core layer 41 is made of carbon fiber polymer foam material.

[0034] The outer wall of the lower hexagonal tube 52 is also connected with complementary blocks and slots. The hexagonal support structure is connected and spliced ​​with the blocks and slots to form an integral honeycomb support layer 5. During installation, it is only necessary to insert adjacent blocks and slots into each other to complete the installation, which is simple to install.

[0035] The core layer 41 is coated on the outside of the honeycomb support layer 5, and fills the inside of the hexagonal support structure through the through holes, and fills the space between the upper support layer 42 and the lower support layer 43. The inside of the hexagonal support structure is filled through the core layer 41, and the space between the upper support layer 42 and the lower support layer 43 is also filled. The upper hexagonal tube 51 and the lower hexagonal tube 52 are connected and their movement is only in the vertical direction, which makes the connection between the upper support layer 42 and the lower support layer 43 more firmly, and cooperates with the core layer 41 to change the gravity pressing on the upper support layer 42 at different angles into the vertical direction, and its rebound direction is upward, making the elastic force fed back by the entire foaming layer 4 more obvious.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
