Description

Hard PVC floor

technical field

The utility model relates to the technical field of PVC floors, in particular to a hard PVC floor.

Background technique

With the development of the country's economy, the supply of timber has become more and more tense. The main reason is that the forest coverage rate in our country is low. After decades of deforestation, large forests have become bare mountains. Government departments have begun to strictly prohibit logging, which has led to a significant reduction in the supply of timber and rising prices. Internationally, with the reduction of forest resources and the enhancement of environmental protection awareness, countries have also formulated relevant policies to restrict logging and export, resulting in fewer and fewer sources of wood panels and more expensive prices. In addition, wooden boards are prone to formaldehyde pollution in construction and home decoration, which is harmful to human health. Therefore, our country's government departments put forward the requirement of "replacing wood with plastic" as early as the 1980s.

At present, the PVC floors on the market are all light or semi-hard floors, which have a certain degree of shrinkage, and the development of hard PVC floors can better solve the problem of PVC floor shrinkage. The pull force of the buckle is greater, and the impact resistance is superior. The current foreign research shows that it has a huge market potential.

PVC floor is a new type of light-weight floor decoration material that is very popular in the world today, also known as "light-weight floor material". It is a popular product in Europe, America and Asia, China, Japan and South Korea, and is popular at home and abroad. Since entering the Chinese market in the early 1980s, it has been widely recognized and widely used in large and medium-sized cities in China, such as homes, hospitals, schools, office buildings, factories, public places, supermarkets, commercial places and other places.

Utility model content

The technical problem to be solved by the utility model is that the PVC floor has poor shrinkage performance and is easy to sag.

In order to solve the above technical problems, the utility model provides a hard PVC floor, including a PVC substrate, a decorative layer is arranged above the PVC substrate, a wear-resistant layer is arranged above the decorative layer, and a UV coating is arranged above the wear-resistant layer. A balance layer is provided under the PVC substrate, a protruding part is provided on one side of the PVC substrate, and a concave part matching the shape of the protruding part is provided on the other side of the PVC substrate. A plurality of cavities are arranged in parallel, a supporting lining is arranged in the cavity, and intersecting supporting rods are also arranged inside the supporting lining. In the hard PVC floor of the utility model, the PVC substrate adopts a rigid PVC foam board, and a cavity is arranged inside the substrate. The supporting lining and supporting rods in the cavity can effectively increase the strength, prevent deformation, and effectively control shrinkage. At the same time, increase the strength and prevent collapse.

A further improvement is that a stabilizing layer is also provided on the upper and lower sides of the PVC substrate, and the connection section between the stabilizing layer above the PVC substrate and the PVC substrate is a transverse wave shape, and the stabilizing layer below the PVC substrate and the PVC substrate are in the same shape. The connection section is longitudinally wave-shaped; above and below the multiple cavities arranged in parallel in the middle of the PVC substrate, reinforcing support plates perpendicular to the cavities are arranged. The stabilizing layer is used to increase the stability of the upper and lower structure and quality of the PVC substrate, and the connection section between the stabilizing layer and the PVC substrate is set to be wavy up and down, and the upper and lower wavy shapes are perpendicular to each other, which can effectively prevent the floor from deforming. A reinforcement support plate perpendicular to the cavity is also provided inside the PVC substrate, and the reinforcement support plates are arranged in parallel, so that the shrinkage of the PVC substrate is not affected while the reinforcement is performed.

Preferably, the cross-section of the cavity is rectangular or circular, and the shape of the supporting lining is adapted to the cross-sectional shape of the cavity, wherein the cross support rods are set as two crosses or three crosses, and the support rods A plurality of them are evenly arranged, and the distance between the support rods is 1-2 times of the connecting length of the diagonal of the rectangle, or 1-2 times of the diameter of the circle.

The hard PVC floor of the utility model, compared with wooden materials, the hard PVC foam material has the characteristics of moisture-proof, anti-corrosion, insect-proof, flame-retardant, no need for paint, non-toxic and tasteless, etc., and can effectively control the shrinkage rate and improve the product quality. In addition, the structure of the PVC substrate is used to effectively improve the strength and effectively prevent deformation and collapse.
