Embodiment Construction

[0029] A method for producing fireproof and waterproof carbonized wood, comprising:

[0030] Step 1 is used to prepare the use liquid. The use liquid includes sodium silicate and water. The mass ratio of sodium silicate and water is 1:4-7, 1:4.5-5.5 is optional, and 1:5 is the best choice. In this embodiment, the sodium silicate is selected: the modulus n is 2.6-2.8, and the density is 1.36-1.50g / cm 3 , the Baume degree is 38.4-48.3, the sodium silicate is easy to dissolve in water and has high strength, high content and high viscosity, which is easy to ensure wood absorption and internal fixation.

[0031] Step 2 is used to make the wood absorb the liquid; preferably, in this embodiment, the vacuum pressurization method is used to make the wood fully absorb the liquid, which includes:

[0032] Step 21, is used to immerse the wood in the use liquid in the container, and vacuumize the container; in this embodiment, the vacuum holding time is 0.25 to 2 hours, and the best param...

Abstract

The invention discloses a production method for fireproof and waterproof carbonized woods, comprising the steps of preparing a using solution, wherein the using solution contains sodium silicate and water based on a mass ratio of 1:(4-7); absorbing the using solution by wood materials; solidifying the wood materials to fix the sodium silicate in the wood materials; and carbonizing the wood materials into the carbonized woods. The production method for fireproof and waterproof carbonized woods has the following advantages: the sodium silicate solution is absorbed by the wood materials, the sodium silicate is fixed in the wood materials, and the wood materials are carbonized; in a carbonizing process, sodium silicate can produce a silica gel solid with excellent water resistance and silicon dioxide, hemicelluloses in the wood materials are degraded, and hydroxyl radicals in cell walls of the wood materials are reduced, so that the production method has the following beneficial effects: 1) the moisture absorbability and the water absorbability of the wood materials are reduced, so that the water resistance is excellent; 2) the fireproof performance of the wood materials is improved, so that the fireproof performance is excellent; 3) the size stability is enhanced, so that the carbonized woods are hard; 4) the biological rotproofness is excellent; and 5) the weather resistance is excellent. Therefore, a wood product which has the advantages of excellent performance, beautiful color and environmental friendliness and is suitable for outdoor environment can be produced.

Description

technical field [0001] The invention relates to a wood protection technology, in particular to a fireproof and waterproof carbonized wood production method. Background technique [0002] Carbonized wood has the following characteristics: 1. The material becomes brittle after high-temperature treatment; 2. The material of carbonized wood is dry after high-temperature treatment, and the fire resistance performance is greatly reduced; 3. The anti-ant and mildew-proof function decreases. Due to the above characteristics, it is not suitable for outdoor decoration or environments that are in contact with water and soil for a long time. Contents of the invention [0003] The invention provides a method for producing fireproof and waterproof carbonized wood, which overcomes the disadvantages of carbonized wood in the background technology. [0004] The adopted technical scheme that the present invention solves its technical problem is: [0005] A method for producing fireproof a...
