Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plastic plates, in particular to an anti-bending plastic raw plate. Background Art
[0002] Plastic boards are an indispensable part of daily working equipment. With the continuous development of the economy, plastics occupy a large proportion in many areas of the national economy. People's requirements for plastics are getting higher and higher, and the types of plastic boards are endless.
[0003] Plastic boards can be divided into raw plastic boards and cooked plastic boards. Generally, cooked plastic boards are made of plastic boards that are mixed with some recycled plastics during production. These boards mixed with recycled plastics have poor quality and certain limitations in use. The counterpart of cooked plastic boards is raw plastic boards, which are made of new materials, have better performance, are more environmentally friendly, and have a wider range of applications.
[0004] However, whether it is raw plastic board or cooked plastic board, when used to make footboards, plastic flooring has a common problem of plastic boards after long-term use by people - easy to bend or break. As for how to prevent the board from breaking, the traditional way is to increase the thickness of the board. Although increasing the thickness of the board will enhance the anti-bending performance of the board, it will also bring about problems such as increased production costs and excessive weight of the board.
[0005] In summary, it is necessary to design a bending-resistant plastic raw board. Utility Model Content
[0006] The utility model aims to provide a bending-resistant plastic raw board, aiming to solve the technical problem in the prior art of taking into account the thinness of the plastic raw board and maintaining a certain bending-resistant performance.
[0007] To achieve the above-mentioned purpose, an embodiment of the utility model provides a bending-resistant plastic raw board, including a bottom plate, a middle plate and a wear-resistant layer stacked in sequence; a PE wire rack is arranged in the middle plate; the PE wire rack is formed by multiple strands of PE wires woven vertically and horizontally, and the PE wires are all tensioned.
[0008] As a preferred implementation, the PE wire rack includes a first PE wire and a second PE wire; the first PE wire and the second PE wire intersect vertically to form the PE wire rack.
[0009] As a preferred implementation, the intersection of the first PE wire and the second PE wire is bonded with glue.
[0010] As a preferred implementation, the cross-sectional diameters of the first PE wire and the second PE wire are between 0.8 mm and 1.2 mm.
[0011] As a preferred embodiment, an even number of reinforcing ribs are provided on the outer surface of the bottom plate; the midpoints of the reinforcing ribs are all connected to the center of the outer surface of the bottom plate. The reinforcing ribs can enhance the rigidity of the bottom plate, making it not easily deformed or broken.
[0012] As a preferred embodiment, the bottom plate, the middle plate and the wear-resistant layer are adhesively connected to each other by glue.
[0013] As a preferred embodiment, the side joints of the bottom plate, the middle plate and the wear-resistant layer are all sealed with glue. After being bonded by glue, the first PE wire and the second PE wire are fixed to each other, so the first PE wire and the second PE wire will not shift, thereby keeping the PE wire rack highly tight all the time.
[0014] As a preferred embodiment, a polyurethane wear-resistant coating is sprayed on the outer surface of the wear-resistant layer. The polyurethane wear-resistant coating is a common wear-resistant coating, having good mechanical properties and excellent wear-resistant properties. Therefore, the polyurethane wear-resistant coating can enhance the strength of the wear-resistant layer, effectively protecting the middle plate and also strengthening the overall anti-bending performance of the plastic raw plate.
[0015] As a preferred embodiment, the bottom plate and the middle plate are made of a mixture of phenolic resin and wood powder. When wood powder is added to phenolic resin, the strength and heat resistance of the plastic can be improved, the cost can be reduced, and the mechanical strength can also be significantly improved.
[0016] As a preferred embodiment, plasticizers are added to the bottom plate, the middle plate and the wear-resistant layer. Plasticizers can improve the plasticity and flexibility of plastics, reduce brittleness, and make plastics easier to process and form. Plasticizers are generally miscible with resins, and are non-toxic, odorless, light and heat-stable high-boiling organic compounds. The most commonly used one is phthalate. For example, in the production of PVC plastics, the more plasticizer is added, the softer PVC plastics can be obtained. If the addition amount of the plasticizer is not more than 10%, rigid PVC plastics can be obtained. Specifically, in this embodiment, the plasticizer content of the bottom plate, the middle plate and the wear-resistant layer all exceeds 10%.
[0017] One or more of the above technical solutions in the anti-bending plastic raw plate provided by the embodiment of the present invention have at least one of the following technical effects:
[0018] 1. Since the PE wires have high strength, the PE wire frame woven from multiple PE wires has good rigidity and is not easily deformed. After the PE wire frame is arranged in the middle plate, the PE wire frame improves the rigidity and anti-deformation ability of the middle plate. When the plastic raw plate is subjected to a large pressure, the PE wire frame exerts a strong supporting effect on the middle plate, thereby preventing the middle plate and even the entire plastic raw plate from deforming or breaking. Therefore, the plastic raw plate has a strong anti-bending effect.
[0019] 2. After the PE wires are tensioned, the rigidity of the entire PE wire frame can be improved, and thus the anti-bending property of the plastic raw plate can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0029] In some embodiments of the present utility model, as Figure 1 - Figure 2 shown, a plastic raw board resistant to bending is provided, which includes a bottom plate 100, a middle plate 200, and a wear-resistant layer 300 stacked and arranged in sequence. A PE wire frame 400 is arranged inside the middle plate 200. The PE wire frame 400 is woven by multiple strands of PE wires intersecting vertically and horizontally, and the PE wires are all tensioned.
[0030] Specifically, the bottom plate 100 plays a role in supporting and holding the entire plastic raw board. And the middle plate 200 is the main component of the plastic raw board. The wear-resistant layer 300 covers one end face of the middle plate 200, and a polyurethane wear-resistant coating is sprayed on the surface of the wear-resistant layer 300. The polyurethane wear-resistant coating is a common wear-resistant coating, which has good mechanical properties and excellent wear-resistant properties. Therefore, the polyurethane wear-resistant coating can enhance the strength of the wear-resistant layer 300, which can not only effectively protect the middle plate 200 but also strengthen the bending resistance of the whole plastic raw board.
[0031] Since the PE line has high strength, the PE wire frame 400 woven from multiple PE lines has good rigidity and is not easily deformed. After the PE wire frame 400 is arranged in the middle plate, the PE wire frame 400 improves the rigidity and anti-deformation ability of the middle plate 200. When the plastic raw plate is subjected to a large pressure, the PE wire frame 400 exerts a strong supporting effect on the middle plate 200, thereby preventing the middle plate 200 and even the entire plastic raw plate from deforming or breaking. Therefore, the plastic raw plate has a strong anti-bending effect.
[0032] After the PE line is tensioned, the rigidity of the entire PE wire frame 400 can be improved, and thus the anti-bending property of the plastic raw plate can be improved.
[0033] In some other embodiments of the present invention, as Figure 1 - Figure 2 shown, the PE wire frame 400 includes a first PE line 410 and a second PE line 420. The first PE line 410 and the second PE line 420 intersect perpendicularly to form the PE wire frame 400.
[0034] In some other embodiments of the present invention, as Figure 1 - Figure 2 shown, the PE wire frame 400 further includes a wire frame surrounded by a third PE line 430, and both the first PE line 410 and the second PE line 420 are connected to the wire frame.
[0035] In some other embodiments of the present invention, as Figure 1 - Figure 2 shown, the PE wire frame 400 is woven from not less than two PE lines. The more PE lines are used in the PE wire frame 400, the closer the structure of the PE wire frame 400 is, the higher its overall strength is, and the more obvious the improvement of the anti-bending performance of the plastic raw plate is.
[0036] In some other embodiments of the present invention, the intersection of the first PE line 410 and the second PE line 420 is bonded with glue. After being bonded with glue, the first PE line 410 and the second PE line 420 are fixed to each other, so the first PE line 410 and the second PE line 420 will not shift, thereby keeping the PE wire frame 400 always highly compact.
[0037] In some other embodiments of the present invention, the cross-sectional diameters of the first PE line 410 and the second PE line 420 are between 0.8 mm and 1.2 mm.
[0038] In some other embodiments of the present invention, as Figure 1As shown, an even number of reinforcing ribs 500 are provided on the outer surface of the bottom plate 100. The midpoints of the reinforcing ribs 500 are all connected to the center of the outer surface of the bottom plate 100. The reinforcing ribs 500 can enhance the rigidity of the bottom plate 100, making it not prone to deformation or breakage. Specifically, in this embodiment, the specific number of the reinforcing ribs 500 is 2. It should be noted that the specific number of the reinforcing ribs 500 is not limited to two. Those skilled in the art can flexibly select and set any even number of reinforcing ribs according to the size of the bottom plate or the actual situation of production cost, and make them all intersect at one point.
[0039] The reinforcing ribs 500 are limited to an even number to ensure that all the reinforcing ribs 500 can be installed on the outer surface of the bottom plate 100 in a symmetrical manner, so as to ensure that the anti-bending and strengthening effects of the reinforcing ribs 500 on each part of the bottom plate 100 are consistent.
[0040] In some other embodiments of the present invention, the side connections of the bottom plate 100, the middle plate 200 and the wear-resistant layer 300 are all sealed with glue. During the process of assembling and connecting the bottom plate 100, the middle plate 200 and the wear-resistant layer 300, there are inevitably certain gaps on the sides between the bottom plate 100 and the middle plate 200, and between the middle plate 200 and the wear-resistant layer 300. Using glue to seal the side connections of the bottom plate 100, the middle plate 200 and the wear-resistant layer 300 can fill the gaps between the plates and make the plates more tightly connected together.
[0041] In some other embodiments of the present invention, the bottom plate 100 and the middle plate 200 are made of a mixture of phenolic resin and wood powder. When wood powder is added to phenolic resin, the strength and heat resistance of the plastic can be improved, the cost can be reduced, and the mechanical strength can be significantly improved at the same time.
[0042] In some other embodiments of the present invention, plasticizers are added to the bottom plate 100, the middle plate 200 and the wear-resistant layer 300. Plasticizers can improve the plasticity and flexibility of plastics, reduce brittleness, and make plastics easier to process and form. Plasticizers are generally miscible with resins and are non-toxic, odorless, light and heat-stable high-boiling organic compounds. The most commonly used one is phthalate. For example, in the production of PVC plastics, the more plasticizer is added, the softer PVC plastics can be obtained. If the addition amount of the plasticizer is not more than 10%, rigid PVC plastics can be obtained. Specifically, in this embodiment, the plasticizer content of the bottom plate 100, the middle plate 200 and the wear-resistant layer 300 all exceeds 10%.
[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
