Problems solved by technology

The carbonized wood board involved in CN108189184A is treated at too high a temperature, and the strength loss of the wood board is large, which is not conducive to the subsequent use of the carbonized wood board
A single treatment temperature also has certain limitations in pursuing the diversification of carbonized wood colors

Embodiment 1

[0066] A kind of preparation method of reinforced, flame-retardant carbonized rubber wood board comprises the following steps:

[0067] (1) Saw rubber wood logs into wooden squares;

[0068] (2) Stack the rubber wood squares and place them in a high-temperature carbonization kiln or carbonization tank for preheating treatment; feed steam, and adjust the preheating temperature from 40°C to ensure that the dry and wet bulb temperatures rise synchronously. To 100°C, the treatment time is 24h;

[0069] (3) Stop feeding steam, continue heating and enter the low-temperature drying treatment stage, gradually increase the temperature from 100°C to 130°C, and the treatment time is 48h;

[0070] (4) In the stage of high-temperature carbonization treatment, continue to feed steam, adjust the carbonization temperature to 170°C, and process for 8 hours;

[0071] (5) In the cooling treatment stage, use atomized water to cool down to about 95°C, and the treatment time is 10 hours; adjust t...

Embodiment 2

[0079] The difference from Example 1 is that the water-soluble flame retardant and reinforcing liquid used in Example 2 are respectively: the water-soluble flame retardant is a mixture of 2 parts of boric acid, 8 parts of disodium tetraborate, and 100 parts of water.

[0080] The reinforcing fluid is water glass, which is made by mixing 30 parts of 40A water glass and 100 parts of water.

[0081] In addition, in Example 2, (2) Stack the rubber wood squares and place them in a high-temperature carbonization kiln or carbonization tank for preheating treatment; steam is introduced to ensure that the dry and wet bulb temperatures rise synchronously , adjust the preheating temperature from 40 to 100 ° C, and the treatment time is 48 hours; (7) Cut the impregnated wood into 2.0cm thick boards by multi-blade sawing.

Embodiment 3

[0083] The difference from Example 1 is that the water-soluble flame retardant and reinforcing liquid used in Example 5 are respectively: the water-soluble flame retardant is ammonium polyphosphate, diammonium hydrogen phosphate, boric acid, and its consumption is 4 parts of ammonium polyphosphate, Diammonium hydrogen phosphate 15 parts, boric acid 4 parts, water 100 parts.

[0084] The reinforcing fluid is water glass, and its dosage is 40 parts of 50A water glass and 100 parts of water.

[0085] In addition, in Example 3, (2) Stack the rubber wood squares and place them in a high-temperature carbonization kiln or carbonization tank for preheating; add steam to ensure that the dry and wet bulb temperatures rise synchronously Next, adjust the preheating treatment temperature from 40 to 100°C, and the treatment time is 36h.

Abstract

The invention belongs to the technical field of wood board processing, and in particular relates to a preparation method of a reinforced and flame-retardant carbonized rubber wood board. The steps of the present invention are as follows: high temperature carbonization treatment and flame retardant enhancement integrated treatment process. High temperature carbonization treatment includes preheating treatment, low temperature drying treatment, high temperature carbonization treatment, and cooling treatment. The flame retardant enhancement integrated treatment includes the preparation of the flame retardant enhancement liquid and the low temperature pressure impregnation treatment. The invention reduces the anti-corrosion treatment process of conventional rubber wood processing, saves the cost, optimizes the conventional rubber wood drying / carbonization process, realizes one-time drying / carbonization, shortens the drying / carbonization time, and also realizes one-time treatment of flame retardant enhancement , Save time and cost, and enhance the flame retardant properties of the sheet. The flame retardant reinforced rubber wood board of the invention has improved density, dimensional stability, surface strength and flame retardant performance, has uniform surface color and high yield, and solves the problem of easy deformation of thin boards by drying / carbonization.

Description

technical field [0001] The invention belongs to the technical field of wood board processing, and in particular relates to a preparation method of reinforced and flame-retardant carbonized rubber wood board. Background technique [0002] When rubber wood is used as a decorative material, because it is a medium-hard wood, it has general resistance to external force and wear resistance. After high-temperature heat treatment (commonly known as carbonization), the color will change and obtain a color similar to that of tropical hardwood, but its hardness is similar to that of mechanical The intensity will decrease to varying degrees. With the enhancement of people's awareness of fire protection and the development trend of this field, indoor and outdoor decorative wood materials must reach a certain fire rating before they are allowed to be used, which puts forward higher requirements for the wood panel industry. The current rubber wood processing methods do not have the functi...
