Embodiment 1

[0013] Embodiment 1 A kind of production technology of solid wood multi-layer composite floor, comprises following process steps:

[0014] ①The leftover fabrics of different specifications produced during the process of rotary cutting, planing or sawing of precious logs are cut and trimmed, and the four sides are relatively straight to form the leftover veneer. The leftover veneer is roughly rectangular and the thickness is not limited. The length can be selected from 200 to 2600mm, and the width can be selected from 10 to 60mm;

[0015] ② Coat both sides of the above surplus veneer with adhesive, the coating amount is 200-250g / m 2 , according to the required specifications layer by layer group embryo pavement;

[0016] ③A cold press is used at a pressure of 19-25kg / cm 2 The pressure is pressed for 2 to 4 hours, and the combined density is 850 to 1100kg / cm 3 , a compressed wooden square with a length of 1200-2600mm and a width and thickness of 400-600mm.

[0017] ④ Cut the...

Embodiment 2

[0018] Embodiment 2 A kind of production technology of solid wood multi-layer composite floor, after making the compressed wooden side as step ① to ③ of embodiment 1, carry out the following operations:

[0019] ④ Slice the above-mentioned compressed wood squares into fabrics with a thickness of 0.6-2.0mm. After drying, the fabrics and multi-layer plywood base materials are produced according to the process of solid wood composite flooring:

[0020]

[0021] In the process of the present invention, the cold-pressed glue used for making compressed wood cubes and the hot-pressed glue used for making composite floors are all environmentally friendly adhesives, and the formaldehyde emission of the final finished product is lower than 1.5 mg / L of the national standard. At the same time, according to the requirements of the product, the remaining materials of the solid wood veneer can be selected to use all the remaining materials of the same wood species, or use the remaining mat...

Abstract

The invention discloses a production technology of a solid wood multi-layer composite floor board, comprising the following technical steps of: (1) cutting and trimming a solid wood veneer excess material into excess material veneers; (2) coating adhesives on two sides of each excess material veneer, assembling the excess material veneers layer by layer according to required standard, and compressing the assembled excess material veneers into a compressed wood cube by a cold press; (3) sawing the compressed wood cube into floor board blanks of certain specification, and forming floor board rabbets after drying; or slicing the compressed wood cube into composite floor board fabrics, and forming the composite floor boards after drying. In the production technology of the solid wood multi-layer composite floor board, veneer excess material of valuable timbers is fully used, the production process and the produced floor board products are both safe and environment-friendly, product quality is steady, and resource is saved.

Description

technical field [0001] The invention relates to a floor production process, in particular to a technique for reproducing wooden floors by using leftovers of precious wood fabrics through a cold pressing process to form high-density wooden squares, that is, a production technique for combined compressed wooden floors. Background technique [0002] The fabrics of the existing solid wood composite flooring are all made of precious wood through rotary cutting, planing or sawing, so many leftovers with different widths and lengths will be produced during the production of the fabrics. At present, most flooring companies will burn these leftovers as firewood, so they have not fully utilized the value of these precious wood leftovers. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a production process of combined compressed wood solid wood multi-layer composite floor that can make full use of the remaining materials of...
