Embodiment Construction
[0017] Such as figure 1 As shown, a one-time thermocompression forming process method of a multi-layer composite floor comprises the following process steps:
[0018] I. The precious wood that needs to play the role of exterior decoration is sliced or rotary cut or sawed to form a strip-shaped solid wood veneer with different thickness and width (determined according to actual needs), as panel 1; common log rotary cut The veneers of different thicknesses are used as veneer 2; the backboard 3 is common solid veneer, such as eucalyptus and poplar.
[0019] II. Coating adhesive on the surface of the veneer 2 , the grain direction of each layer of veneer 2 is criss-cross. Each layer of veneer 2 is glued together, at 13kg / cm 2 Press into the base material under the pressure condition;
[0020] III. Cut the four sides of the above-mentioned base material pressed together for a certain period of time (40 to 60 minutes) into standard boards;
[0021] IV. Cold press the upper and...

One-step hot-press forming process for a multilayer composite floor board is disclosed, comprising the following steps: slicing or rotary-cutting or saw cutting woods into strips as bezel panel of floor board; rotary-cutting common logs into veneers as veneers; pasting each layer of the veneers together, or cold pressing one layer of veneer and one layer of density board or shaving board and alsoone layer of veneer again into butt logs; cutting butt logs into dimension boards; cold-pressing dimension boards and strip bezel panels and a one-piece backplane together to form blank board; prepressing blank boards for some time, and then hot-pressing into floor boards without paint; cutting floor boards without paint into floor veneer, and then grooving and tongue, painting, and packaging finished products. The invention can not only improve productivity and decrease energy cost, but also solve the problem of debonding efficiently and keep the product quality stable; thus the invention decreases production cost greatly, is safe and pollution-free.
Description
technical field [0001] The invention relates to a floor production process, in particular to a one-time thermocompression forming process of a multi-layer composite floor. Background technique [0002] Existing multi-layer solid wood composite flooring generally adopts two hot pressing processes, resulting in products that are easy to warp and deform, have a long production cycle, high energy consumption, and high overall cost, which does not meet the current national requirements for low-carbon economic industry development. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a one-time hot-press forming process for multi-layer composite flooring that can improve the production efficiency of floor hot-press forming, reduce energy consumption, be safe and environmentally friendly, and have stable product quality. [0004] In order to solve the above-mentioned technical problems, the one-time thermocompression molding...
