Abstract

The invention discloses a super-hydrophobic wood with the pores of a wood body filled with super-hydrophobic substances. The preparation steps comprise: (1) the wood is put into a die; (2) certain amount of super-hydrophobic substance powder is added into the die to submerge the wood; the pressure in the die is lifted to 1-50MPa on a press; the temperature rises to 80-100 DEG C and is maintained for 0.5-20h; then the pressure is lowered to 0MPa; the material is taken out when the temperature rises to 105-110 DEG C; (3) the taken-out wood is cooled to the room temperature and scraped the super-hydrophobic substance on the surface to derive the super-hydrophobic wood. The contact angle between the super-hydrophobic wood and the water is 150 degrees and the roll angle is less than 10 degrees. The layer is tasteless and nontoxic, thereby having a broad application prospect in the fields such as lossless transportation of liquid, self-cleaning, water and damp resistance, etc. The method for preparing super-hydrophobic wood provided by the invention has the advantages of simple operation technology, good controllability, low cost, no complicated chemical treatment, no expensive equipment and industrialization facilitating.

Description

technical field [0001] The invention relates to a superhydrophobic wood, and also relates to a preparation method of the superhydrophobic wood. Background technique [0002] Inspired by the lotus leaf effect, solid materials with superhydrophobic surfaces (the contact angle between the surface of the material and water is greater than 150°, and the water droplets have a small rolling angle on the surface) have attracted extensive interest. Due to the characteristics of waterproof, anti-fog, anti-oxidation and self-cleaning, superhydrophobic surfaces have broad application prospects in scientific research, industrial and agricultural production, and daily life. For example, it can be applied to building materials and exterior wall coatings with self-cleaning function, textiles with self-cleaning function, loss-free transportation of liquids, moisture-proof packaging materials, biomedical materials that inhibit blood coagulation and blood pollution, etc. [0003] It is well k...
