Embodiment 1

[0042] Take 200ml of MTES, 300ml of TEOS, and 100ml of water, put them into a flask and stir thoroughly, then add 10% hydrochloric acid to adjust the pH value to 1, then add 150ml of ethanol, gradually raise the temperature to 75°C, react for 60 minutes, then add ammonia water, The pH value was adjusted to 10, and the stirring reaction was continued for 30 minutes to obtain a transparent and clear sol, which was left at room temperature for later use.

[0043] Poplar wood after natural drying was taken as the wood to be treated, and a wood sample of 300×20×20mm was made. Put the sample into the processing tank of the processing system shown in Figure 1, start the vacuum pump to pump the pressure in the processing tank to 0.04MPa, and inhale the prepared in step 1 into the processing tank while keeping the vacuum state of the processing tank unchanged. Sol, make the wood sample completely immersed in the sol liquid, keep it for 30 minutes, open the inlet valve, release the vacu...

Embodiment 2

[0046] Take 350ml of MTES, 400ml of TEOS, and 90ml of water, put them into a flask and stir well, then add hydrochloric acid with a concentration of 6%, adjust the pH to 4, then add 100ml of ethanol, gradually raise the temperature to 80°C, and after 30 minutes of reaction, add ammonia water, The pH value was adjusted to 7, and the stirring reaction was continued for 40 minutes to obtain a transparent and clear sol, which was left at room temperature for later use.

[0047] Poplar wood after natural drying was taken as the wood to be treated, and a wood sample of 300×20×20mm was made. Put the sample into the processing tank of the processing system shown in Figure 1, start the vacuum pump to pump the pressure in the processing tank to 0.06MPa, and inhale the prepared in step 1 into the processing tank while keeping the vacuum state of the processing tank unchanged. Sol, make the wood sample completely immersed in the sol liquid, keep it for 60 minutes, open the inlet valve, re...

Embodiment 3

[0050] Take 400ml of MTES, 200ml of TEOS, and 50ml of water, put them into a flask and stir thoroughly, then add 1% hydrochloric acid to adjust the pH value to 6, then add 50ml of ethanol, gradually raise the temperature to 70°C, react for 90 minutes, then add ammonia water, The pH value was adjusted to 12, and the stirring reaction was continued for 20 minutes to obtain a transparent and clear sol, which was left at room temperature for later use.

[0051] Poplar wood after natural drying was taken as the wood to be treated, and a wood sample of 300×20×20mm was made. Put the sample into the processing tank of the processing system shown in Figure 1, start the vacuum pump to pump the pressure in the processing tank to 0.095MPa, and inhale the prepared in step 1 into the processing tank while keeping the vacuum state of the processing tank unchanged. Sol, make the wood sample completely immersed in the sol liquid, keep it for 90 minutes, open the inlet valve, release the vacuum...

Abstract

The present invention discloses a preparation method of vitrified composite wood material. Said preparation method includes the following steps: (1), preparing MTES-TEOS sol; (2), making the wood material to be treated undergo the process of negative pressure and positive pressure treatment in a treatment tank and impregnating the wood material to be treated with the sol prepared in step 1 in the process of negative pressure treatment; and (3), making the above-mentioned wood material undergo the process of ageing treatment in the room, then making gel treatment in the drying oven so as to obtain the invented vitrified composite wood material.

Description

technical field [0001] The invention relates to a preparation method of ceramic composite wood. Background technique [0002] With the development and application of modern science and technology, people have higher and higher requirements for the performance of materials, and some application fields of wood have been replaced by materials that emerged later. However, when people realize the importance of sustainable development of materials, environmental materials are proposed. At the time of the concept of wood, we paid attention to the fact that wood is an environmentally harmonious material, and realized that it has the characteristics of environmental materials in essence, so that people re-examined the status and role of wood in the field of materials science, and made a contribution to this ancient material. Infused with new energy and fresh content. [0003] Although wood has good environmental coordination and high strength-to-weight ratio, it has unique advantage...
