Problems solved by technology

[0006] The processing methods of the above invention patents and known technologies for wood only simply change the properties or surface patterns of the wood. For the property of the wood itself, the strength, the above processing methods have no way to change it.
However, the shortcoming of insufficient strength of wood hinders its use in many aspects.

Embodiment 1

[0020] A kind of processing method of high-strength wood, step A, according to mass parts, with dried 100kg wood (the density of wood is 0.35g / cm 3 , the thickness is 5cm) in the reaction kettle, 500kg of water, make the water completely submerge the wood, heat the water to boiling, add 50kg of sodium hydroxide, 40kg of sodium metabisulfite and 10kg of calcium hydroxide after 5min and continue to boil for 10h After completing the reaction, drain the liquid, re-add 500kg of water, boil for 20min, and take out the wood after repeating twice.

[0021] Step B. Put the wood in a hot press, control the temperature at 110-105° C., press at 6 MPa, and press for 18 hours to obtain a high-strength wood.

[0022] Step C, after the wood is processed into the required shape, anticorrosion treatment is carried out by the brushing method.

[0023] The sample number is QW-1.

Embodiment 2

[0025] A kind of processing method of high-strength wood, step A, according to mass parts, with dried 125kg wood (the density of wood is 0.42g / cm 3 , the thickness is 10cm) in the reaction kettle, 750kg of water, make the water completely submerge the wood, heat the water to boiling, add 75kg of sodium hydroxide, 50kg of sodium metabisulfite and 12kg of calcium hydroxide after 8min and continue to boil for 12h ; After completing the reaction, drain the liquid, re-add 750°C of water, boil for 25 minutes, and take out the wood after repeating twice.

[0026] Step B. Put the wood in a hot press, control the temperature at 120-125° C., press at 7.5 MPa, and press for 15 hours to obtain a high-strength wood.

[0027] Step C, after the wood is processed into the required shape, anticorrosion treatment is carried out by diffusion method.

[0028] The sample number is QW-2.

Embodiment 3

[0030] A kind of processing method of high-strength wood, step A, according to mass parts, with dried 150kg wood (the density of wood is 0.45g / cm 3 , thickness is 12cm) in the reaction kettle, 1000kg of water, make the water completely submerge the wood, heat the water to boiling, add 100kg of sodium hydroxide, 60kg of sodium metabisulfite and 15kg of calcium hydroxide after 10min and continue to boil for 14h After completing the reaction, drain the liquid, add 1000kg of water again, boil for 30min, and take out the wood after repeating twice.

[0031] Step B. Put the wood in a hot press, control the temperature at 125-130° C., press at 9 MPa, and press for 12 hours to obtain a high-strength wood.

[0032] Step C, after processing the wood into the desired shape, carry out anti-corrosion treatment with hot and cold bath method.

[0033] The sample number is QW-3.

Abstract

The invention belongs to the technical field of material manufacture and particularly relates to a processing method of high-strength wood. The processing method comprises the following three main steps: firstly fixing 100-150 parts of dried wood in a reaction kettle, and treating by using a chemical method; then placing the wood in a hot-pressing machine, controlling the temperature to be 110-130DEG C and the pressure to be 6-9MPa and carrying out hot pressing for 12-18 hours; finally, after processing the wood into a needed shape, and carrying out preservative treatment. Compared with the prior art, the processing method of the high-strength wood has the advantages that the method is simple and is easy in implementation, the manufactured wood has very-high mechanical strength, is low indensity and light in mass per unit volume, and has very-good application prospect in all the fields such as aerospace.

Description

technical field [0001] The invention belongs to the technical field of material manufacturing; in particular, it relates to a processing method of high-strength wood. Background technique [0002] Wood is one of the first materials used by human beings. It has a wide range of sources and diverse uses, and is an indispensable natural resource for human beings. For a long time, people have invented many methods of processing wood. [0003] CN1910024B discloses a method of processing wood and a processed wood product in which even a wood grain formed on a product having a three-dimensional shape such as an exterior member for an industrial product can be easily changed to form a decorative pattern. On the outer surface (1A) and inner surface (1B) of the cut wood (1) having a curved surface corresponding to the mold used to compress the wood (1), there are provided protrusions (2), recesses (2a), The recess (3) and the plane cutting part (4). These protrusions and recesses ar...
