Embodiment 1

[0037] (1) The first drying step: dry the masson pine wood to a moisture content of 14% according to a conventional method.

[0038] (2) Carbonization step: then neatly stack the dried masson pine wood and press 1t / m on the top of the wood pile 2 The standard pressurized steel plate frame pours concrete briquettes, and then puts them into wood carbonization equipment, heats up and humidifies rapidly, the temperature rises to 90°C, and the humidity is humidified to 80% relative humidity, keep for 4 hours, and then use the stepwise heating method according to Raise the temperature to 125°C at a rate of 20°C / h and keep it for 4 hours. At this time, the relative humidity is 100%. Then use a stepwise heating method to raise the temperature to 200°C at a rate of 15°C / h and keep it at the highest temperature for 4 hours. After the end, use the method of spraying atomized water to quickly cool down the wood until the temperature in the carbonization equipment is less than 120°C, stop ...

Abstract

The invention relates to a functional improving method of wood, in particular to the functional improving method of the wood, and the method comprises steps of carbonizing the wood, executing flame-retardant treatment, enhancing the surface and molding in one step. The invention particularly relates to a flame-retardant enhanced solid wood profile and an improved manufacturing method of the flame-retardant enhanced solid wood profile, belonging to the technical field of improving the functions of wood and processing the wood. The method comprises the following steps: (1) first drying; (2) carbonizing; (3) executing the flame-retardant treatment at the normal pressure; (4) second drying; (5) enhancing the surface and molding in one step; and (6) recovering the water content. Compared with the prior art, the technical scheme of the invention has the following advantages: the production technology is simple, the production volume is large, the energy consumption is low, the outturn rate is high, and the production cost is low. The flame-retardant enhanced solid wood profile has the following more prominent advantages of good flame-retardant performance, surface enhancement, steady size, good corrosion-resistance and weather-resistance performances, appeared texture and richer color.

Description

technical field [0001] The invention relates to a method for improving wood function, in particular to a method for improving wood function through carbonization of wood, flame retardant treatment and surface reinforcement and fixation, and in particular to a fire retardant reinforced solid wood profile and its improved manufacturing The method belongs to the technical fields of wood functional improvement and wood processing. Background technique [0002] Chinese patent document CN101603623A discloses a technical patent of "surface reinforced solid wood profile, floor and manufacturing method thereof", the manufacturing method including (1) drying log profile; (2) compressing log profile in a hot press at 210-250°C; (3) keeping the compressed log profile for 20-60 minutes; (4) controlling the moisture content of the log profile between 6% and 9%. In the above scheme, the dried wood is directly compressed in a hot press at 210-250°C. Due to the poor permeability of the wood...
