Description

Technical Field

[0001] The utility model relates to the technical field of flooring, in particular to an LVT flooring with a high temperature resistant and flame retardant structure. Background Art

[0002] Floor, that is, the surface layer of the floor or floor of a house, is made of wood or other materials. At present, most of the existing LVT floors are made of pressed debris. Due to the tight structure of LVT floors, it is easy for the LVT floors to be broken due to uneven ground during installation. At the same time, due to the long-term use of LVT floors, it is easy for LVT floors to encounter combustion points and cause burns, which reduces the use efficiency of LVT floors. Secondly, most of the existing LVT floors adopt simple structures. Due to long-term walking on the floor, it is easy for the structure between the floors to loosen and emit noise, which leads to low performance of the floor and cannot meet the needs of LVT floor use.

[0003] For example, the utility model with application number 202010861701.X belongs to the field of plastic flooring, and particularly relates to an indoor LVT plastic flooring and a preparation method thereof. The present invention comprises: a wear-resistant layer, a color film and a co-extruded layer, characterized in that: the wear-resistant layer, the color film and the co-extruded layer are laminated in sequence; the co-extruded layer comprises a co-extruded core layer and a co-extruded bottom layer laminated with the co-extruded core layer; the co-extruded layer has the characteristic of warping toward one side of the co-extruded bottom layer during use, and this characteristic can offset the warping trend of the co-extruded layer after the color film and the wear-resistant layer are laminated, so that the board has the property of not being easy to warp.

[0004] The above-mentioned comparative documents form the base plate body through several layers of structural layers bonded in sequence. The co-extruded layer has the characteristic of warping toward the side of the co-extruded bottom layer during use, which can avoid the probability of warping of the floor and improve the quality of the floor. However, the floor of the above-mentioned structure does not have special functions in terms of fire prevention and moisture resistance. Only relying on the fire resistance of the LVT floor material itself may not meet the fire protection level requirements of building decoration. For this reason, we propose such an LVT floor with a high temperature resistant and flame retardant structure. Utility Model Content

[0009] Furthermore, the cross-section of the clamping block is in a "concave" shape, the opposite side of the protrusion on the upper end of the clamping block is polished into an arc shape, and the cross-section of the lower end of the limit block is in an arc shape; the clamping block of the above structure can clamp two adjacent floors together to avoid the displacement of the floors. At the same time, the arc-shaped top makes it easier and more convenient to insert the floor into the clamping block, avoiding abnormal extrusion of the limit block and causing damage to the limit block.

[0010] Furthermore, the left and right sides of the floor are fixedly bonded with edging on the outer surface of the slot; the edging is provided to wrap the various layers of the floor structure together, thereby improving the bonding strength between the various layers of the floor and reducing the possibility of warping of the floor, thereby ensuring that each layer of the structure can achieve its respective performance.

[0012] Furthermore, the fiber layer is located between the base layer and the elastic layer; by providing the fiber layer, the bonding strength between the base layer and the elastic layer can be increased, so that the base layer and the elastic layer are firmly bonded together, thereby avoiding floor delamination and accelerating the rate of floor damage.

[0013] The utility model provides an LVT floor with a high temperature resistant and flame retardant structure, which has the following beneficial effects:
