specific Embodiment approach 1

[0016] Embodiment 1: The method for preparing super-double-sparse wood by magnetron sputtering in this embodiment is implemented according to the following steps:

[0017] 1. Soak the wood in anhydrous ethanol and deionized water for ultrasonic cleaning for 15 to 30 minutes in turn to obtain wood with a clean surface;

[0018] 2. Place the clean wood in the vacuum chamber of the magnetron sputtering device, install the metal target for magnetron sputtering, turn on the vacuum pump body, and wait until the vacuum degree in the vacuum chamber reaches 10 -2 Pa, after passing in argon, adjust the radio frequency power to 110W~205W for sputtering for 20~30 minutes, then adjust the radio frequency power to 310~400W, and then perform sputtering treatment to obtain wood with a roughness layer on the surface;

[0019] 3. Put the wood with the roughness layer on the surface obtained in step 2 into the perfluorodecanoic acid solution for 5-20 minutes, take it out and dry it naturally, an...

specific Embodiment approach 2

[0021] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the wood described in Step 1 is poplar, larch, sylvestris or bamboo. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the material of the metal target described in Step 2 is iron, nickel, copper, aluminum or zinc. Other steps and parameters are the same as in the first or second embodiment.

Abstract

The invention relates to a preparation method for wood with the super-amphiphobic structure on the surface, in particular to a method for preparing the super-amphiphobic wood through magnetron sputtering. The method aims to solve the problems that the processes of existing methods for preparing a super-hydrophobic coating on the surface of the wood are complicated and the hydrophobic property is low. The method for preparing the super-amphiphobic wood comprises the steps of 1, soaking the wood in absolute ethyl alcohol and deionized water sequentially for carrying out ultrasonic cleaning on the wood; 2, placing the wood with the surface cleaned in a vacuum chamber of a magnetron sputtering device, installing a metal target, vacuumizing the vacuum chamber, guiding argon gas into the vacuum chamber and then carrying out the sputtering treatment for obtaining the wood with a rough layer on the surface; and 3, soaking the wood with the rough layer on the surface in nonadecafluorodecanoic acid solutions and drying the wood for obtaining the super-amphiphobic wood. According to the method, the rough surface is formed through the magnetron sputtering method, the contact angle of water drops and oil drops on the surface of the obtained super-amphiphobic wood is 153-161 degrees, and the super-amphiphobic property is high.

Description

technical field [0001] The invention relates to a preparation method of a super-amphiphobic structure on the surface of wood. Background technique [0002] As an environmentally friendly material, wood is widely used in furniture, construction, interior decoration and other fields. Because wood has a large number of hydrophilic groups and rich void structure, it is easy to absorb moisture when placed in a humid environment for a long time, causing the wood itself to deform, crack, mildew, decay, and degrade. The construction of a superhydrophobic coating on the hydrophobic treatment of wood will transform the hydrophilic state of the wood into superhydrophobicity, which can stabilize its own size, and at the same time take into account the excellent properties of anti-corrosion, mildew resistance, self-cleaning, etc., and solve the limited application of wood, etc. technical problems, broaden its scope of use and increase its added value. [0003] The Chinese patent applic...
