The ceramic tile has the advantages of good wear resistance, water resistance, moisture resistance, corrosion resistance, certain pressure resistance, hard texture, convenient material selection, long service life, wide application in various indoor environments, deep favor of consumers and the widest application range. The plastic flooring has the advantages of simple laying, convenient scrubbing, light weight, small volume, flexible use, random cutting according to requirements and strong environment adaptability. The solid wood floor or the composite wood floor is mainly of a wood structure, so that the solid wood floor or the composite wood floor is good in elasticity, comfortable in foot feeling, non-toxic and tasteless, ideal in use in a living room, and a preferred decorative material for the surface of a bedroom.
The decorative products have outstanding advantages and are respectively long, but have disadvantages. The ceramic tile has high hardness and smooth surface, so that people can slip easily after splashing water, and the ceramic tile is particularly dangerous for the old. In recent years, the range of use thereof has been affected to some extent. The floor leather has low strength and high toughness, is easy to generate static electricity, can form wrinkles or deform under long-time extrusion, is easy to age and break, and is not beneficial to long-term use. The solid wood floor or the composite wood floor needs to use a large amount of wood, is not beneficial to environmental protection, has poor impact resistance and buffering effect on the surface of the floor, and is easy to have hidden troubles such as screen breaking and the like when electronic products such as mobile phones, flat plates and the like fall down the floor carelessly in modern society in which mobile phones and flat plates are widely applied.
Through search, the prior art has developed a composite wood floor with a two-layer structure, such as the chinese patent application no: 2006201259419, filing date: the invention is named as follows in 2006, 11, 30 days: the utility model provides a solid wood composite floor, this application discloses a solid wood composite floor, and it includes two-layer structure of dash board and base plate, and the base plate adopts and indicates the fishplate bar, and it has flexible balanced strip groove to open on the upper faying face of base plate and dash board. The flexible balance strip groove is 3 ~ 6 rectangular grooves of seting up along the length direction of panel. The lower surface of the base plate is provided with lower telescopic balance bar grooves which are staggered with the telescopic balance bar grooves on the upper combining surface. Because the base plate adopts the cold splicing finger joint plate and the base plate and the surface plate are compounded by strong white latex, the composite board does not contain formaldehyde components completely and is a green and environment-friendly product; the telescopic balance strip groove reduces the internal stress of the board, has small deformation amount under the conditions of being affected with damp, heated or dried, and reduces the possibility of bulging and slotting of the floor. However, the application has the following defects which are difficult to overcome: (1) the solid wood composite floor is completely made of solid wood, has high production cost, destroys the ecological environment and does not conform to the principle of sustainable development; (2) the adhesive force between the surface plate and the substrate is small, and the phenomenon of glue failure is easy to occur; (3) the floor has poor impact resistance and buffering effect.
