Example Embodiment

[0033] Example 1

[0034] (1) The first high-temperature and high-humidity rapid drying step: stack the 24mm thick masson pine fast-growing timber in the drying kiln. First open the humidification valve to quickly humidify the drying kiln and directly humidify to a relative humidity ≥98% to make the drying kiln Fill with water vapor, then keep the humidification valve open, keep the relative humidity ≥98%, and open the heating valve for the first time to quickly heat to the dry bulb temperature 1℃ higher than the wet bulb temperature and keep it for 5 hours, continue to humidify and control the relative humidity in the drying kiln to 99~ 100%, heating makes the dry bulb temperature in the kiln rise from 103 to 135°C. Masson pine with a wood thickness of 24mm is heated at 2°C for 2 hours and dried for 3 days to reduce the moisture content of the wood to 6%.

[0045] Example 2

[0046] (1) The first high-temperature and high-humidity rapid drying step: stack 100mm thick poplar wood in the drying kiln. First open the humidification valve to quickly humidify the drying kiln and directly humidify to a relative humidity ≥98%, so that the drying kiln Fill it with water vapor, then keep the humidification valve open, keep the relative humidity ≥98%, and open the heating valve for the first time to quickly heat to the dry bulb temperature 2℃ higher than the wet bulb temperature and keep it for 25h, continue to humidify and control the relative humidity in the drying kiln to 99 ~100%, heating makes the dry bulb temperature in the kiln rise from 103 to 135°C, and the poplar thickness is 100mm at 10.5h and heated at 2°C for 15 days to reduce the moisture content of the wood to 12%.

Abstract

The invention relates to a method of wood function modification, especially to a surface flame retardation reinforced solid wood and a manufacturing method thereof, belonging to the technical fields of wood function modification and wood processing. The invention provides the manufacturing method of the surface flame retardation reinforced solid wood, and the method comprises: (1) a step of a first high-temperature and high-humidity rapid drying; (2) a step of flame retardation processing; (3) a step of a second high-temperature and high-humidity rapid drying; (4) a step of wood surface reinforcement; and (5) a step of heat-treatment fixing. The processed surface flame retardation reinforced solid wood has outstanding advantages of flame retardation, reinforced surface, stable size, corrosion resistance, weathering resistance, visualized texture and full color. The technical scheme provided by the invention integrates advantages of four kinds of treatments such as the high-temperature and high-humidity drying, flame retardation treatment, surface reinforced treatment and charring heat treatment to fix the wood, overcomes disadvantages of the four treatments, and is beneficial for industrial production.

Description

technical field [0001] The present invention relates to a method for improving wood functionality, in particular to a fast-growing surface flame-retardant reinforced solid wood improved by such processes as high-temperature and high-humidity drying of wood, flame-retardant treatment and reinforcement, and heat treatment and fixation, and a manufacturing method thereof. A surface flame-retardant reinforced solid wood and a manufacturing method thereof belong to the technical fields of wood functional improvement and wood processing. Background technique [0002] Chinese patent document CN1868704A discloses a technical patent of "a wood carbonization treatment method". 2 The standard pressurized steel plate frame pours concrete briquettes, and then puts them into the wood carbonization equipment; b. In the wood carbonization equipment, adopt a step-type continuous heating method, and increase the temperature by 3 to 7 °C every 4 to 6 hours. 120-140°C; c. Adopt stepwise contin...
