Description

Technical Field

[0001] This utility model relates to the field of plastic sheet technology, specifically to an integrated plastic sheet. Background Technology

[0002] In the construction of sports fields such as plastic running tracks and basketball courts, multi-layer composite structure designs are often adopted to balance surface functionality (such as elasticity and wear resistance) and base stability (such as load-bearing strength). Currently, these fields mostly adopt a composite structure of "plastic surface layer + base board". The plastic surface layer provides the elasticity and friction performance required for sports, while the base layer is mostly made of high-strength materials such as PP injection molded board as the load-bearing foundation. The two layers are bonded and fixed together by adhesive.

[0003] Due to the large difference in surface energy between plastic surface layers (mostly polar materials) and PP injection molded sheets (non-polar materials), it is difficult to form a stable bond by relying solely on the intermolecular forces of the adhesive. This can easily lead to delamination and peeling. Especially under high-frequency trampling, impact, or temperature changes, the adhesive layer is prone to cracking due to stress concentration, causing the plastic surface layer to fall off, affecting the service life of the venue and the safety of sports activities. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an integrated plastic sheet that solves the problem that relying solely on the intermolecular forces of adhesives makes it difficult to form a stable bond, leading to delamination and peeling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated plastic sheet, comprising: a plastic component, wherein an injection molding component is adhesively bonded to the bottom of the plastic component; the injection molding component comprises a PP injection molding sheet, wherein a cross-shaped grid groove is formed at the bottom of the PP injection molding sheet, an adhesive layer is fixedly connected to the top of the PP injection molding sheet, and posts are fixedly connected to the outer wall of the PP injection molding sheet, wherein the posts are arranged in a linear array along the outer wall of the PP injection molding sheet.

[0006] Preferably, the PP injection molded plate has slots in its wall, and the slots are arranged in a linear array along the outer wall of the PP injection molded plate.

[0007] Preferably, the wall of the adhesive plate layer has a lattice of holes, and the lattice of holes are arranged in a linear array along the outer wall of the adhesive plate layer.

[0008] Preferably, the plastic component includes an injection-molded plate layer, the material of which can be EPDM granules, PU material, or silicone PU. The outer wall of the injection-molded plate layer is fixedly connected with protrusions, and the protrusions are arranged in a linear array along the outer wall of the injection-molded plate layer.

[0009] Preferably, the outer wall of the injection-molded plate layer is bonded to the outer wall of the adhesive plate layer by an adhesive, and the inner wall of the adhesive plate layer is in contact with the outer wall of the protrusion.

[0010] This utility model provides an integrated plastic sheet. It has the following beneficial effects: (I) This integrated plastic sheet has a dot matrix of holes in the bonding layer of the injection molding component. After the adhesive penetrates and cures, it forms "micro-adhesive columns" that are physically anchored to the injection molding layer of the plastic component. Compared with simple planar bonding, it increases the contact area and improves the mechanical interlocking force, solving the problem of weak bonding between PP injection molding sheet and plastic layer due to material differences (different polarities). The protrusions of the plastic component contact the bonding layer and form a "point-surface" composite support structure after the adhesive layer cures. When subjected to impact, trampling or shear force, the protrusions can buffer energy through small deformation and disperse the stress to the entire adhesive layer, avoiding cracking caused by local stress concentration. It is especially suitable for high-frequency dynamic stress scenarios such as running tracks and basketball courts.

[0011] (II) This integrated plastic board uses a linear array design of the posts and slots on the outer wall of the PP injection molded board. Adjacent boards can be quickly connected through the "post-slot" connection, which can achieve positioning without complicated tools, improving paving efficiency and shortening the construction cycle. The spliced ​​post-slot structure forms an integral locking frame. Combined with the adhesive seal between the boards, it can resist the thermal expansion and contraction stress caused by temperature changes in the field, reduce the risk of warping and cracking, ensure the flatness after large-area paving, and meet the requirements of sports field for ground precision.

[0014] 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.

[0015] Please see Figure 1-5 This utility model provides a technical solution: an integrated plastic sheet, comprising: a plastic component 1, to which an injection molding component 2 is glued by adhesive; the injection molding component 2 includes a PP injection molding plate 22, to which an adhesive layer 21 is fixedly connected, to which an insert post 25 is fixedly connected, and the insert post 25 is arranged in a linear array along the outer wall of the PP injection molding plate 22; a slot 23 is provided in the wall of the PP injection molding plate 22, and the slot 23 is arranged in a linear array along the outer wall of the PP injection molding plate 22; and a dot matrix hole 24 is provided in the wall of the adhesive layer 21, and the dot matrix hole 24 is arranged in a linear array along the outer wall of the adhesive layer 21.

[0016] The plastic component 1 includes an injection-molded sheet layer 11, with protrusions 12 fixedly connected to the outer wall of the injection-molded sheet layer 11, and the protrusions 12 are arranged in a linear array along the outer wall of the injection-molded sheet layer 11. The outer wall of the injection-molded sheet layer 11 is bonded to the outer wall of the bonding sheet layer 21 by adhesive, and the inner wall of the bonding sheet layer 21 is in contact with the outer wall of the protrusions 12.

[0017] The material type of injection molding layer 11 can be selected according to different usage scenarios. For example, in EPDM plastic running tracks, the raw material of injection molding layer 11 is mainly EPDM rubber, and the structure is divided into colored rubber granule layer and black rubber layer (bottom layer).

[0018] Permeable plastic running track: Its characteristics are excellent breathability, good elasticity, no bubbling, and excellent drainage performance. During the laying process, a slope of 0.8% from the outside to the inside is constructed to ensure that water is drained within about 40 minutes after rain.

[0019] Composite plastic running track: "Composite" means that the bottom layer is made of black granular elastic material, which is used as a breathable running track to reduce construction costs and time. The surface is made of PU layer and wear-resistant layer to improve the wear resistance of the track. Composite running track has strong flatness, elasticity, impact resistance and nail resistance.

[0020] Hybrid plastic running track: The hybrid plastic running track has a two-layer structure. The injection-molded plate layer 11 is made of PU granules (or EPDM environmentally friendly granules), and the core layer is made of full PU mixed with some rubber granules. The hybrid plastic running track has strong elasticity, impact resistance, and wear resistance. It can be used in all weather conditions and can be used immediately after rain.

[0021] All-plastic running track: The injection-molded board layer 11 base layer is made of natural and artificial rubber, and the main material is two-component polyurethane, which is mixed with other materials and vulcanized and hardened at a high temperature of 300 degrees Celsius.

[0022] Precast synthetic running tracks: Precast running tracks consist of a three-layer structure – a friction surface layer, a shock-absorbing bottom layer, and an adhesive layer in between. In addition to having excellent elasticity, strength, toughness, and shock absorption, precast synthetic running tracks do not produce particles, have excellent shock absorption, and their anti-slip and wear-resistant properties are not affected by rain.

[0023] Injection molding layer 11 is made of silicone PU. Silicone PU has advantages in material properties, including moderate elasticity, diverse colors, high resilience, waterproofness, high cost-effectiveness, and low requirements for the foundation, making it popular in basketball courts or outdoor sports fields. Injection molding layer 11, composed of different materials, is divided into fully prefabricated and semi-prefabricated types. In the fully prefabricated case, injection molding layer 11, PP injection molding plate 22, and bonding layer 21 are all manufactured. Only the injection molding component 2 needs to be assembled on site first, and then the plastic component 1 can be bonded to the injection molding component 2. In the semi-prefabricated case, PP injection molding plate 22 and bonding layer 21 are both manufactured and assembled on site. Then, the plastic component 1 is constructed on site on the injection molding component 2. The actual size of the plastic board can be adjusted according to the actual site conditions.

[0024] This integrated plastic panel achieves a stable bond between the plastic layer and the PP injection molding layer through a layered design and structural connection of plastic component 1 and injection molding component 2, balancing functionality and ease of installation. Its core working logic is based on the synergistic effect of "layer bonding + mechanically assisted fixing", the specific principle of which is as follows: The overall structure of the device consists of an upper plastic component 1 and a lower injection-molded component 2 bonded together with adhesive. The injection-molded component 2 serves as the load-bearing foundation, and its core component, the PP injection-molded plate 22, is formed using injection molding, possessing good structural strength and stability. An adhesive layer 21 is fixedly connected to the top of the PP injection-molded plate 22, acting as a direct connection carrier with the plastic component 1. The dot matrix holes 24 (arranged linearly along the outer wall) in the wall of the adhesive layer 21 enhance the adhesion of the adhesive. When adhesive is applied to the surface of the adhesive layer 21, some of the adhesive penetrates into the dot matrix holes 24 and solidifies, forming "micro-adhesive pillars." This mechanical interlocking effect improves the bonding strength between the plastic component 1 and the injection-molded component 2, avoiding the risk of peeling caused by relying solely on intermolecular forces in the adhesive layer.

[0025] The injection-molded plate layer 11 of the plastic component 1 serves as a functional surface layer. The protrusions 12 (arranged in a linear array along the outer wall) fixedly connected to its outer wall are in contact with the inner wall of the adhesive plate layer 21, which further optimizes the bonding stability of the two-layer structure. The protrusions 12 not only increase the contact area between the plastic component 1 and the adhesive, but also form a "point-to-surface" support structure after the adhesive layer is cured, dispersing the local stress under the action of external force. Especially when subjected to impact or shear force, the protrusions 12 can buffer energy through deformation and reduce the probability of adhesive layer cracking.

[0026] In addition, the outer wall of the PP injection molded plate 22 of the injection molding component 2 is also designed with posts 25 and slots 23 (both arranged in a linear array along the outer wall) to realize the splicing and installation of multiple integrated plastic plates. When laying a large area, the posts 25 of adjacent plates can be inserted into the corresponding slots 23 to form a physical locking structure. Combined with the adhesive seal between the plates, this not only improves the flatness of the overall paving, but also resists the deformation stress caused by thermal expansion and contraction of the site. It is suitable for scenarios that require continuous paving, such as plastic running tracks and basketball courts.
