Solid wood composite floor with impregnated paper veneer and production process of solid wood composite floor

Abstract

The invention discloses a solid wood composite floor with impregnated paper veneer and a production process of the solid wood composite floor. The solid wood composite floor comprises a decorative thin board, a buffer board, a thick core board and a bottom board, wherein the thick core board serves as a core layer and is covered with the buffer board; the buffer board is covered with the decorative thin board; and the bottom board is arranged under the thick core board in a composite manner. Through the addition of a density board, the board surface cracking resistance of the solid wood composite floor can be remarkably improved through the impregnated paper veneer, the solid wood composite floor can be applied to a geothermal environment, and cracks are not easy to appear on the board surface; through the special watering and positioning processes, the problem that after the density board is assembled and hot-pressed with impregnated paper, spots are easy to appear on the board surface and the difficulty in processing a product with synchronous wood grain is high can be solved; and meanwhile, narrow wood slats serve as main raw materials of a substrate and are processed into the thick core substrate in a variety of ways such as splicing or series connection, so that the use of fast growing wood veneer can be reduced, the wood utilization rate can be improved, and forest resources can be saved.

Description

technical field [0001] The invention relates to the technical field of flooring, in particular to an impregnated paper veneered solid wood composite floor and a production process thereof. Background technique [0002] Conventional solid wood composite flooring is based on criss-crossing fast-growing veneer plywood, and the veneer of precious tree species is used as the decorative surface layer. It is obtained by hot-pressing gluing process. The use increases the manufacturing cost of the product and discourages some price-sensitive consumers. The impregnated paper parquet on the market uses the impregnated paper commonly used in laminate flooring as a decorative surface layer to replace the veneer of precious trees. It has rich patterns, three-dimensional effect, wear resistance, low manufacturing cost and low price, and is favored by many enterprises and low-end consumers; [0003] The existing impregnated paper solid wood composite flooring is directly glued to the venee...

Problems solved by technology

[0002] Conventional solid wood composite flooring is based on criss-crossing fast-growing veneer plywood, and the veneer of precious tree species is used as the decorative surface layer. It is obtained by hot-pressing gluing process. The use increases the manufacturing cost of the product and discourages some price-sensitive consumers. The impregnated paper parquet on the market uses the impregnated paper commonly used in laminate flooring as a decorative surface layer to replace the veneer of precious trees. It has rich patterns, three-dimensional effect, wear resistance, low manufacturing cost and low price, and is favored by many enterprises and low-end consumers;

[0003] The existing impregnated paper solid wood composite flooring is directly glued to the veneer with the impregnated paper cured by hot pressing, and the crack resistance of the board surface is poor. On the one hand, the veneer has many layers and a large amount of glue, which is not environmentally friendly, and the aesthetics of the product locks are not enough; Wood and other wood are often unable to be put into use due to insufficient size, which reduces the utilization rate of wood and is not conducive to the conservation of forest resources. For impregnated paper solid wood composite flooring, however, due to the inconsistent density and moisture content of each pine wood, the surface of the product is prone to waves and washboard-like appearance defects due to the expansion and rebound of the wood to different degrees after being pressed and glued with other materials. , the present invention proposes an impregnated paper veneer solid wood composite floor and its production process to solve the problems existing in the prior art
