Technique and method for manufacturing technical wood laminted wood

Abstract

The invention relates to a process for producing a technical wood integrated material and a preparation method thereof. The process comprises the following: step one, selecting a material, in which, the water content of the wood material is controlled to lower than 12 percent, dyeing liquor is prepared in a dyeing tank at a temperature of between 85 and 95 DEG C for 1 to 2 hours; step two, pumping imbibition by a vacuum pump with negative pressure of between minus 0.88 and minus 0.95MPa, impregnating the wood material for 2 hours under a pressure of between 0.98 and 1.2MPa after impregnating the wood material under reduced pressure for 1 hour, vacuum pumping for half an hour to control the water content to between 12 and 18 percent; step three, preparing phenolic resin glue, in which, the wood material is placed in a 15 to 20 percent adhesive flume to be impregnated for 20 to 40 minutes, and drying the wood material at low temperature; and step four, placing the wood material in a mould, controlling the density to carry out compression forming, perforating a tip on the mould after forming, placing the mould in a drying kiln at a high temperature of between 60 and 160 DEG C for solidifying for 8 to 20 hours, and discharging the wood material from the kiln. The invention has the advantages of simple production process, convenient operation, various colors and various wood veins, and adjustable density of the wood material.

Description

Technical field: [0001] The invention relates to a production process and a preparation method of a technical wood-glued wood, in particular to a production process and a preparation method of a technical wood-glued wood of veneer and sapwood after rotary cutting. Background technique: [0002] At present, the production method of scientific and technological wood in the prior art is to dye the poplar veneer and then laminate the mold to shape it. Shaped wood or square wood is vacuum-pressurized and impregnated with preservatives, and it is difficult to achieve anti-corrosion effect inside the wood; the bottom corner waste and sapwood waste of the above-mentioned various woods are inconvenient to be reused, wasting natural wood resources. Invention content: [0003] The purpose of the present invention is to provide a production process and preparation method of science and technology wood-glued wood, which is to utilize the production technology and preparation method of ...
