Description

Lap floor

Technical field

The invention relates to a novel lap rubber floor, in particular to a new lap rubber floor made of plastic, wood plastic, rubber or rubber.

Background technique

Rubber flooring includes flooring made of plastic, wood, rubber or rubber. Rubber flooring can meet the requirements of indoor flooring materials, and has many features, such as scratch resistance, wear resistance, non-slip, shock absorption, flame retardant, sound insulation, heat insulation, hygiene, safety, moisture resistance, environmental protection and recycling. The energy consumption for use and processing is much lower than other floors. Rubber flooring can also be designed and manufactured according to different needs into a variety of colors and varieties, such as imitation wood flooring, imitation tiles, imitation stone flooring, imitation carpet flooring, and very realistic. As the concept changes and people continue to contact and understand the rubber flooring made of plastic, wood plastic, rubber or rubber, many consumers choose rubber flooring as a decorative material for home and commercial or public places.

Traditional rubber flooring has two shapes, one is rectangular and the other is square. Most rectangular floors are made of wood-like flooring, and most of the square floors are made of imitation carpet and imitation stone. The thickness of the rubber floor is generally between 1.00 mm and 5.00 mm and the wear layer is between 0.07 mm and 1.00 mm. The rubber floor is divided into two types of backing glue and dry bottom (without glue). When the adhesive floor is laid, the release paper is torn off and directly attached to the ground. When the dry bottom product is laid, the solvent glue is applied on the ground, and the solvent is volatilized and the glue is moderately cured before the floor is laid. When the ground is not flat, self-leveling cement should be used for ground treatment to make the ground have a certain degree of flatness. The ground treated with the rubber flooring products and methods of these structures has the following disadvantages: 1. The paving is not correct when it is biased; 2. The construction is difficult and the construction cost is high; 3. When using these products, the floor glue or coating Glue will adhere to the ground, it is difficult to remove, can not maintain the original ground state; Fourth, when the floor is replaced, it is difficult to completely remove the floor; Fifth, the bottom of the floor to be removed will be stuck with cement and sand, affecting recycling and use; 6. Dry bottom products are laid with solvent glue. It takes a certain time for the solvent to evaporate and cannot be stayed for a short time.

The announcement number is CN The invention patent of 2791155Y discloses an easy-to-splicing plastic floor, as shown in Fig. 1 and Fig. 2, including a floor body 1', and a bottom layer 2', the floor body 1' and the bottom layer 2' are misaligned with each other. Together, the portion of the bottom layer 2' that protrudes from the floor body 1' constitutes a connecting strip 3', and the portion of the floor body 1' where the bottom layer 2' protrudes constitutes the connecting strip 4'. When laying, the connecting strips 4' on one plastic floor are covered on the corresponding connecting strips 3' on the other plastic floor to join the two floors together. The product is simple and convenient to connect, and the construction speed is improved. The laid floor maintains the advantages of traditional plastic floor patterns and vivid patterns, and is easy to replace and can maintain the original ground state. However, there are still some shortcomings in the above products. First, the product is made up of two sheets of misaligned sheets. The bonding surface needs to be glued with glue. The use of glue is large, which will increase the material cost and Reduce the flame retardancy of the product and increase the volatiles in the product; Second, the thickness of each sheet of the product is relatively thin, reducing the possibility of other mechanical processing; three, two sheets are coated with hot melt elastic glue, the whole The middle of the product is completely glued. The glue layer is not easy to creep due to its strength, and it is easy to be deformed by the influence of the environment or loses its viscosity and falls off. The floor body 1' located on the surface layer is easily lifted, and the glue layer is set to make the product The expansion coefficient becomes large, and the expansion and contraction are easy to occur when the ambient temperature changes. Fourth, the sheet of the product is thin, and the connecting strip 4' located on the floor body 1' remains suspended for a long time before use, and is easy to sag, resulting in Deformation, affecting the use and appearance of the product; 5. In order to prevent the glue from being damaged by the plasticizer, the glue should be isolated from the floor body 1' and the bottom layer 2'. The reason is that the floor body 1' and the bottom layer 2' are in contact with the glue, and the whole surface treatment is required, and the processing materials and labor are used more, and the cost is large; 6. Because the floor body 1' and the bottom layer 2 'The production of harder floor materials, the connection side is not elastic, when the temperature drops, the product shrinks, causing the adhesive layer to be easily pulled and broken, and at the same time producing a large shrinkage seam; 7. For convenient laying, The product is designed such that the floor body 1' size is larger than the bottom layer 2', and the difference is 1.00mm~2.00mm. When the temperature rises, the product expands, and most of the pressing force concentrates on the floor body 1' of the surface layer, hindering Automatic product repair, easy to produce end jacking and warping; Eight, because the product is first processed separately from the floor body 1' and the bottom layer 2', and then glued and glued, each layer of the floor is designed and processed. It is necessary to separately set the balance layer, and it is not possible to share the balance layer. It requires more resin materials, the process is more manual and the heat energy consumption is larger, and the continuous mode production difficulty is increased. 9. The glue layer of the product is located on the floor body 1' Base material Between 2', it is equivalent to being sandwiched in the middle position. It is difficult to remove the glue during product recycling, which affects the recycling and reuse of the product, and increases the difficulty and adaptability of reuse. 10. Because the bottom layer 2' is thick and hard. It is difficult to cut, and it is difficult and troublesome to replace the partially damaged floor.

Since the product disclosed in CN 2791155Y still has many shortcomings, it is necessary to develop a more ideal simple grounding plate.
