Manufacturing method of novel three-layer curtain spliced floor

Abstract

The invention relates to a manufacturing method of novel three-layer curtain spliced floor. The manufacturing method specifically comprises the following steps of selecting a radiation pine as a board core, selecting eucalyptus board veneers as middle boards, selecting a birch veneer or beech veneer as a bottom veneer, and selecting a solid wood veneer or melamine gummed colored paper as a surface veneer; paving the eucalyptus board veneer on the radiation pine after the eucalyptus board veneer is subjected to double-face gluing, then transversely paving one eucalyptus board veneer subjected to double-face gluing, paving about 70 eucalyptus board veneers according to the method, and feeding to a cold press to be pre-pressed for 2 hours to be formed; after pre-pressing forming, adjusting the distance between 28 saw blades in the middle of a multi-blade saw to be 4 cm, adjusting the distance between the two saw blades at the two ends and the adjacent saw blades to be 7 cm, enabling the sawing depth of the saw blades to be 0.75 cm, and conducting cold pressing for 2 h; performing hot pressing treatment; after hot pressing, repairing the double surfaces of a base material with putty powder, and performing sanding after cooling; and pasting the surface veneer and the bottom veneer on the base material, and then performing hot pressing. The method has the beneficial effects that the applicable material selection range is wide, the performance is stable, the process is simple, industrial implementation is easy, and pollution is small.

Description

Technical field[0001]The present invention relates to the field of floor technology, and specifically, a new three-layer curtain floor manufacturing method is specifically made.Background technique[0002]With the reduction in precious tree resources and countries strengthen the protection of primitive forest resources, the price of solid wood flooring is rising, and on the other hand, due to the production of solid wood flooring, the production process is behind the production process from the realization of the production of solid wood flooring. The reason why the processing machinery is poor, so that a large amount of precious tree species floor blanks produces dry defects and processing defects, lowering wood grades, a large amount of material, resulting in a large amount of precious tree species wood waste.[0003]The three-layer composite floor is one of the mainstream product categories in the composite structural floor product. The current three-layer composite floor mainly incl...

Problems solved by technology

Therefore, for the increasingly tense precious hardwood resources, the three-layer composite floor still has the resource problem of excessive consumption of precious hardwood

[0004] Therefore, many wooden floor manufacturers now make the defective boards into small wooden strips and lay them on the floor with plywood, medium density fiberboard or high density fiberboard as the base material, but this kind of floor is prone to warping and deformation. Defects, severe and even cracking, with the increase of the substrate width, the possibility of warping and deformation of the floor will increase, and the amount of warping and deformation will also increase greatly; at the same time, this floor is not easy to machine, processing The precision is low, it is not easy to pave, and it is prone to defects such as seam separation after paving and use. In addition, these floors have poor corrosion and weather resistance, poor insect resistance, and short service life.
