Method for manufacturing rhombic wood-bamboo composite floor board

Abstract

The invention provides a rhombic wood-bamboo composite floor board. The rhombic wood-bamboo composite floor board is manufactured by compounding purely natural wood and bamboo materials serving as raw materials, wherein the top surface of the floor board adopts a high-quality wood veneer; the bottom surface adopts a wood chips spliced veneer; the substrate of a pallet board of the floor board adopts an array structure which is formed by compounding a bamboo curtain (or a bamboo mat) with wood chips alternately and has criss-cross grain; the shape is characterized in that: a plane rhombus serves as a base unit; tenons and mortises are reserved on the four side surfaces; the total surface layer is coated by a moisture-proof wear-resistant paint; the floor board has uniform stress and small deformation; when the floor board is heated or moisturized, generated internal stress is diffused in all directions to be isotropic, so the deformation is very small; the moisture-proof size stability reaches 0.02 to 0.03 percent which is far lower than the national standard requirement of 0.30 percent; therefore, the rhombic wood-bamboo composite floor board cannot cause the phenomena of arch or crack; the use quality of the floor board is ensured; floor boards are simple and convenient to splice because of special shape; a large area of rich patterns can be spliced; and the patterns have attractive appearance, stereoscopic impression, toughness of bamboo and softness of wood, and particularly can achieve a warm sense effect in inhabitable rooms.

Description

Technical field [0001] The invention relates to a method for manufacturing and processing a diamond-shaped floor with wood and bamboo composite materials. Background technique [0002] At present, the known flooring made of bamboo or wood is generally flat and rectangular in shape, such as the popular paint-free, nail-free solid wood floor, wear-resistant bamboo floor, and medium-to-high-density composite floor. , all of them are rectangular or long rectangular in shape, with a width of about 50-120 mm and a length of no more than 2 meters; there are also square floors or small parquet floors in the early market, although they can be spliced ​​into various patterns. font, back-shaped, ladder-shaped etc., but its unit block is still a rectangle, just smaller in size. Other forms of flooring, as long as they are made of wood or bamboo, including synthetic bamboo, wood particle board, medium and high-density fiberboard, bamboo composite board, and wood composite board, are all...

Problems solved by technology

But its disadvantages are: single shape, lack of change in composition

[0003] At present, there are also special-shaped splicing floors made of bamboo and wood on the market, such as triangular, hexagonal, diamond-shaped floors, and even garden-shaped or five-sided plum-shaped floors. Defects, that is, because their substrates are all made of single-quality wood or bamboo splicing and composite, there is a longitudinal or horizontal direction of natural growth, and their inherent physical properties must have anisotropy. When they are heated or damp The size of the vertical or horizontal expansion and contraction is different. After a long time of splicing the special-shaped floor, it is easy to produce gaps, especially for the diamond-shaped floor. The earth affected their sales
