Embodiment 1

[0026] Example 1: At 40KN / m 2 Under pressure, use 320 mesh sandpaper to polish the surface of the moso bamboo board that needs to be processed, and use a vacuum cleaner to remove the powder on the surface to obtain a clean surface;

[0027] Spray 3wt% hydrogen peroxide on the clean surface, the spraying amount is 100g / m 2 , After spraying, leave it at room temperature for 1.5 hours, rinse it with deionized water for 3 times, and use a 100°C heat gun to quickly dry it to obtain a surface-pretreated moso bamboo board;

[0028] The edge of the surface of the obtained moso bamboo board to be treated is sealed with a detachable silica gel strip to form a pool-shaped frame; an equal volume of 12g / L cobalt nitrate hexahydrate solution and 27g / L 2-methylimidazole aqueous solution are quickly mixed and then poured into the pool-shaped frame , the total amount of mixed solution is 0.6L / m 2 . After standing at room temperature for 6 hours, pour out the liquid in the pool-like frame, q...

Embodiment 2

[0031] Example 2: At 40KN / m 2 Under pressure, use 320-grit sandpaper to polish the surface of the fir board that needs to be processed, and use a vacuum cleaner to remove the powder on the surface to obtain a clean surface;

[0032] Spray 7wt% hydrogen peroxide on the clean surface, the spray amount is 30g / m 2 , After spraying, leave it at room temperature for 2 hours, rinse it with deionized water for 3 times, and quickly dry it with an 80°C hot air gun to obtain a surface-pretreated fir board;

[0033] Seal the edge of the obtained fir board surface to be treated with a detachable silicone strip to form a pool-like frame; quickly mix an equal volume of 16g / L cobalt nitrate hexahydrate solution and 36g / L 2-methylimidazole aqueous solution and pour it into the pool-like frame , the total amount of mixed solution is 0.4L / m 2 . After standing at room temperature for 4 hours, the liquid in the pool-like frame was poured out, the surface of the fir board was quickly rinsed 3 ti...

Embodiment 3

[0036] Example 3: At 40KN / m 2 Under pressure, use 320-grit sandpaper to polish the surface of the pine board that needs to be processed, and use a vacuum cleaner to remove the powder on the surface to obtain a clean surface;

[0037] Spray 5wt% hydrogen peroxide on the clean surface, the spraying amount is 60g / m 2 , After spraying, leave it at room temperature for 2 hours, rinse it with deionized water for 3 times, and use a 120°C hot air gun to quickly dry it to obtain a surface-pretreated pine board;

[0038] Seal the edge of the surface of the obtained pine board to be treated with a detachable silicone strip to form a pool-like frame; quickly mix an equal volume of 14g / L cobalt nitrate hexahydrate solution and 30g / L 2-methylimidazole aqueous solution and pour it into the pool-like frame , the total amount of mixed solution is 0.5L / m 2 . After standing at room temperature for 5 hours, pour out the liquid in the pool-like frame, quickly rinse the surface of the pine board...

Abstract

The invention discloses a manufacturingmethod of colored super-hydrophobic bamboo wood, wherein the whole manufacturing process is carried out in an open environment at room temperature, organic solvents and reaction devices are not needed, operation is easy, and therefore large-scale amplification manufacturing is easy; meanwhile, a metal organic framework material growing on the surface of bamboo wood is used as a precursor, a metal hydroxide prepared through in-situ conversion has good binding force on the surface of the bamboo wood, the adhesive force of a manufactured super-hydrophobic coating is improved, and the super-hydrophobic stability of the super-hydrophobic coating is improved; and the color of the prepared hydroxide can be regulated and controlled by changing the types of metal salts used in the in-situ conversion preparation process of the double-metal hydroxide, so that the manufacturing of the colored super-hydrophobic bamboo wood is realized.

Description

technical field [0001] The invention relates to the field of bamboo wood production, in particular to a production method of colored superhydrophobic bamboo wood. Background technique [0002] With the pursuit of low-carbon life, bamboo and wood materials are increasingly being used in outdoor landscape architecture, furniture, flooring, decoration materials, and large-scale structural engineering materials. With the expansion of product use, people put forward more and higher requirements for product functions. At present, the functions of bamboo and wood materials are single, and the product functions are far behind the market's great demand for multi-functional products. Thereby develop the bamboo-wood plank with different functions, improve the added value of product, expand its use, satisfy the consumption demand of people's increasing day by day, just seem very urgent. In addition, due to the nutrients such as sugar, starch, protein and fat, bamboo wood is prone to m...
