Description

Technical Field

[0001] The utility model relates to the field of wood plastic flooring, in particular to a high-molecular low-temperature wood plastic flooring. Background Art

[0002] Wood plastic flooring is a new type of environmentally friendly wood plastic composite material product. The wood phenol produced in the production of medium and high density fiberboard is added with recycled plastic and made into wood plastic composite material through granulation equipment, and then extruded into wood plastic flooring.

[0003] Existing wood-plastic flooring is easily affected by weather and environment when laid and used in public places such as outdoor parks. Outdoor floors will generate high temperatures under direct sunlight, which will cause burning or even scalding to people's feet, especially toddlers and children who are more likely to be affected during outdoor activities. In addition, the upper surface of the wood-plastic flooring is exposed to sunlight for a long time, which will make its upper surface temperature higher. The temperature difference between the upper and lower surfaces and the interior of the wood-plastic flooring is prone to expansion and cracking over time.

[0004] Patent publication number CN201649543U discloses a wood-plastic flooring comprising a polymer foam layer with a wood-plastic layer disposed on its surface. This wood-plastic flooring has a polymer foam layer in the middle and a wood-plastic layer on the surface. The lightweight polymer foam layer effectively reduces the weight of the formwork, creating a solid fill in the center of the flooring for a more aesthetically pleasing appearance. The wood-plastic layer on the surface also ensures the surface hardness and strength of the flooring, without compromising its usability. While this wood-plastic flooring offers the advantages of both lightness and aesthetics, the presence of the foam layer increases the temperature difference between the upper and lower surfaces of the flooring, making it more susceptible to deformation after prolonged use, leading to expansion and cracking. Therefore, it is necessary to propose a polymer, low-temperature wood-plastic flooring to address this issue. Utility Model Content

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] The present application provides a high-molecular low-temperature wood-plastic floor as shown in Figures 1-4 The present application provides a high-molecular low-temperature wood-plastic floor as shown in

[0024] In order to solve the problem that the wood-plastic floor lacks effective support at the center position and is prone to deformation due to gravity after long-term use, the present application combines the wood-plastic bottom shell 1 and the wood-plastic cover plate 2 to form a hollow square plate containing a center hole groove 3, and the center hole groove 3 is provided with a high-molecular foaming filling layer 4 inside, and the high-molecular foaming filling layer 4 is provided with a plurality of wave-shaped support plates 5 inside. When laying the floor, the keel is laid on the ground, and then the wood-plastic floor is fixed on the keel. When the user steps on the wood-plastic cover plate 2 of the wood-plastic floor, the wood-plastic cover plate 2 transmits the pressure to the wave-shaped support plate 5, the wave-shaped support plate 5 deforms, the wave-shaped support plate 5 transmits the concentrated stress to both sides, which can reduce the damage of the concentrated stress to the wood-plastic floor and improve the service life of the wood-plastic floor. When the user's foot leaves, the wave-shaped support plate 5 can reset and support at the bottom of the wood-plastic cover plate 2, which can avoid deformation of the wood-plastic floor. At the same time, the wave-shaped support plate 5 can play a buffering role when deforming, which can reduce the hard contact between the user's foot and the wood-plastic floor, thereby reducing the sound of the user stepping on the wood-plastic floor, and avoiding noise when walking to affect the residents downstairs.

[0025] It should be noted that the wave-shaped support plate 5 can be made of synthetic plastic, which has certain deformation ability while having the necessary strength. Such materials are known in the art and are not limited.

[0026] The outer side of the high-molecular foam filling layer 4 is provided with a cladding net 6. The cladding net 6 on the upper surface of the high-molecular foam filling layer 4 is in movable contact with the lower surface of the wood-plastic cover plate 2, and the cladding net 6 on the lower surface of the high-molecular foam filling layer 4 is in movable contact with the inner wall of the bottom of the wood-plastic bottom shell 1. The cladding net 6 can completely wrap the high-molecular foam filling layer 4, so the high-molecular foam filling layer 4 containing the wave-shaped support plate 5 can be produced separately and then directly inserted into the wood-plastic bottom shell 1, without the need for separate filling, which can save production time.

[0027] The lower surface of the wood-plastic bottom shell 1 is provided with a rough sound-absorbing layer 7. The provision of the rough sound-absorbing layer 7 can reduce the sound of friction between the wood-plastic floor joist and the wood-plastic floor, and has a certain sound-absorbing effect, which can enhance the sound insulation effect of the wood-plastic floor.

[0028] Further, the wood-plastic bottom shell 1 is provided with a U-shaped ventilation groove 8 on both sides, and the two U-shaped ventilation grooves 8 are symmetrically arranged with the center line of the wood-plastic bottom shell 1. The U-shaped ventilation groove 8 can be used to install the wood-plastic floor, and when two wood-plastic floors are spliced together, the U-shaped ventilation grooves 8 on the adjacent two wood-plastic floors will form a complete hole. When the U-shaped ventilation grooves 8 on multiple floors are connected, a circulating channel can be formed. By connecting a pipeline at the end to the outside, a circulating air flow can be formed inside the floor, which can make the internal temperature of the floor lower and make the indoor environment cooler.

[0029] It should be noted that a fan, refrigeration equipment or heating equipment can be provided at the connected pipeline according to needs. Such technology is a conventional setting and is not limited.

[0030] The high-molecular foam filling layer 4 is provided with a plurality of wave-shaped cavities, and a plurality of wave-shaped support plates 5 are respectively embedded in the plurality of wave-shaped cavities.

[0031] The wood-plastic cover plate 2 is provided with raised lines on four sides, which are clamped with the inner walls of the four sides of the wood-plastic bottom shell 1. The provision of the raised lines can make the wood-plastic cover plate 2 and the wood-plastic bottom shell 1 clamp more stably, and can avoid the warping of the wood-plastic cover plate 2.

[0032] The upper surface of the high-molecular foam filling layer 4 is provided with a glue layer, which is adhered and connected with the lower surface of the wood-plastic cover plate 2. The provision of the glue layer can adhere and connect the high-molecular foam filling layer 4 and the wood-plastic cover plate 2 together, with high stability.

[0033] In addition, the heat insulation auxiliary material can be added into the raw material during the production of the wood-plastic floor to inhibit the heat generated by sunlight, thereby effectively reducing the temperature rise of the wood-plastic floor, reducing the temperature difference between the upper and lower sides of the wood-plastic floor, and avoiding the expansion and cracking of the wood-plastic floor due to the large temperature difference.
