Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] Figure 1 to Figure 4 It is a schematic diagram of the structure of an energy-saving and environmentally friendly composite floor. It can be seen from the figure that it is a long strip floor with mutually spliced mortise 1 or tongue 2 on both sides of its long and short sides. The panel 3 on the upper surface of the floor and the base plate 4 on the lower surface are made of wood veneers with a thickness of 1-4 mm. Between the face plate 3 and the bottom plate 4 is a core plate 5, and the core plate 5 is made of polyurethane foam material. The density of polyurethane foam material is 300-400Kg / m 3 .
[0024] The manufacture method of above-mentioned energy-saving and environment-friendly composite floor is:
[0025] (1) slice the log into a panel 3 and a base plate 4 with a thickness of 1 to 4 millimeters with a planer, leave a tr...
