preparation example Construction
[0028] The invention provides a preparation method of large-scale transparent wood or bamboo, comprising the following steps:
[0029] (1) place the original wooden board or the original bamboo board in the swelling liquid and soak it to obtain the swelling wooden board or the swelling bamboo board;
[0030] (2) carrying out lignin modification to the wet-swelled wood board or the wet-swelled bamboo board obtained in the step (1) to obtain a white veneer; the quality of the lignin in the white veneer is greater than or equal to that of the original wood board or the original bamboo board 50% of the mass of lignin;
[0031] The lignin modification includes: soaking the swollen wood board or the swollen bamboo board in a lignin modifier solution for modification treatment; the lignin modifier solution includes a mixture of hydrogen peroxide and an alkaline solution or hydrogen peroxide;
[0032] (3) putting the white veneer obtained in the step (2) into a solvent, and performi...
Embodiment 1
[0065] A preparation method of large-format transparent wood, the steps are:
[0066] (1) get a poplar, cut out a piece of wood chip (length × width × thickness=50cm × 50cm × 2mm) with a thickness of 2mm from the chord section of the wood, as the original board; the original board is placed in a sodium hypochlorite solution (solute mass The fraction is 5%), heat up to boiling, soak for 20min, take it out and clean it to obtain a swollen wooden board;
[0067] (2) carrying out lignin modification on the swollen wood board obtained in the step (1), taking out and washing with water to obtain a white veneer; the quality of the lignin in the white veneer is greater than or equal to 76.5 of the quality of the lignin in the original wood board %;
[0068] The lignin modification includes: soaking the swollen wood board in a mixed solution of hydrogen peroxide and sodium hydroxide, then adjusting the pH of the mixed solution to 11 with hydrogen peroxide or sodium hydroxide solution,...
Embodiment 2
[0075] A preparation method of large-format transparent bamboo, the steps are:
[0076] (1) along the surface of the bamboo, a piece of bamboo with a thickness of 1.5mm (length×width×thickness=10cm×6cm×1.5mm) is cut out, as the original bamboo board; the original bamboo board is placed in a sodium hypochlorite solution (solute mass Fraction is 5%) in, be warmed up to boiling, soak 30min, it is taken out and cleaned, obtain swollen bamboo board;
[0077] (2) carrying out lignin modification on the swollen bamboo board obtained in the step (1), taking out and washing with water to obtain a white veneer; the quality of the lignin in the white veneer is greater than or equal to the quality of the lignin in the original bamboo board 71.8% of ;
[0078] The lignin modification includes: soaking the swollen bamboo board in a mixed solution of hydrogen peroxide and sodium hydroxide, then adjusting the pH of the mixed solution to 11 with hydrogen peroxide or sodium hydroxide solution,...
