Example Embodiment
[0065] Example 1
[0066] 1. Cut the beech wood into 0.3mm thin wood to make the beech wood material;
[0067] 2. Soak the beech veneer material in the BL-environmental flame retardant solution with a concentration of 30% by mass, keep the soaking temperature at 50 ℃, soak for 40 minutes, take it out to obtain the soaked beech veneer, and then pave the soaked beech veneer. Drying is carried out at a temperature of 25-30°C until the moisture content of the beech veneer is 14% to obtain flame-retardant beech veneer 3;
[0068] The prepared flame-retardant veneer has a moderate moisture content, so as to ensure that the composite veneer has good flexibility, and will not break when the wood is bent due to the low moisture content. At the same time, it will not crack due to the high moisture content of the veneer after the construction. ; The flame retardant used in the embodiments of the present invention is BL-environmentally friendly flame retardant, except for BL-environmental flame...
Example Embodiment
[0079] Example 2
[0080] 1. Cut the beech wood into 0.4mm thin wood to make the beech wood material;
[0081] 2. Soak the beech veneer material in the BL-environmental flame retardant solution with a concentration of 40% by mass. Keep the soaking temperature at 40℃. After soaking for 30 minutes, take it out to obtain the soaked beech veneer, and then spread the soaked beech veneer. Drying is carried out at a temperature of 30-40℃, and the moisture content of the beech veneer is 16% to obtain the flame-retardant beech veneer;
[0082] 3. Between the upper and lower hot-pressed steel plates 1 of the wood-based panel hot press, two PTFE membranes 2 are set, and then between the upper and lower PTFE membranes 2, the blanks are assembled in a bottom-up order , That is, place cotton mesh cloth, PES film and flame-retardant veneer 3 in the order from bottom to top to form a pre-pressed slab. The schematic diagram of the flame-retardant decorative veneer is as follows figure 1 As shown, th...
Example Embodiment
[0090] Example 3
[0091] 1. Cut the beech wood into 0.20mm thin wood to make the beech wood material;
[0092] 2. Soak the beech veneer material in the BL-environmental flame retardant solution with a concentration of 50% by mass. Keep the soaking temperature at 70℃. After soaking for 20 minutes, take it out to obtain the soaked beech veneer, and then pave the soaked beech veneer. Drying treatment is carried out at a temperature of 20-25°C until the moisture content of the beech veneer is 15% to obtain the flame-retardant beech veneer;
[0093] 3. Between the upper and lower hot-pressed steel plates 1 of the wood-based panel hot press, two PTFE membranes 2 are set, and then between the upper and lower PTFE membranes 2, the blanks are assembled in a bottom-up order , That is, place cotton mesh cloth, PES film and flame-retardant veneer 3 in order from bottom to top to make a pre-pressed slab. The schematic diagram of the flame-retardant decorative veneer is as follows figure 1 As sh...
