Solid wood composite floor of two-layer structure and manufacturing method

Abstract

The invention discloses a solid wood composite floor of a two-layer structure and a manufacturing method. The solid wood composite floor comprises a finger joint splicing board substrate and a decorative panel, wherein the decorative panel and the finger joint splicing board substrate are glued together and fixed into a whole; a stress groove is formed in the back of the finger joint splicing board substrate and perpendicular to the surface wood fiber direction. The manufacturing method for the solid wood composite floor comprises the following steps: step 1, putting the finger joint splicing board substrate and the decorative panel together into a balancing kiln to achieve a 6-8% water content; step 2, bonding the balanced finger joint splicing board substrate and decorative panel together; step 3, forming the stress groove in the laminated and bonded two-layer whole board blank; step 4, conducting tongue-and-groove treatment on the laminated and bonded two-layer whole board blank with the stress groove; step 5, conducting seal coating on the four surfaces of the two-layer plain board subjected to the tongue-and-groove treatment; step 6, painting the plain board subjected to the seal coating. According to the manufacturing method, less large-diameter woods are utilized, and the utilization ratio of small-diameter woods is improved; compared with the conventional laminated and multi-layer solid wood composite floor, the solid wood composite floor provided by the invention is higher in appearance grade and approaches an effect of solid woods.

Description

technical field [0001] The present invention relates to solid wood composite flooring. Background technique [0002] At present, there is no two-layer structure solid wood composite floor with finger-jointed panel base material on the market. Generally, multi-layer solid wood, three-layer solid wood, solid wood floor or laminate floor are used for interior floor decoration; wall decoration is limited to small-scale decoration (such as TV background wall, photo wall, lines, etc.) due to price factors, not only the amount of wood used Large, high cost, and due to the large number of layers, the number of glue layers is also large, and it is not environmentally friendly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a two-layer structure solid wood composite floor and its production method, which can reduce the amount of wood used, reduce the cost, meet the environmental protection requirements, obtain the textur...
