specific Embodiment approach 1

[0023] Specific implementation mode one: the treatment method of this embodiment pollution-free improving wood weather resistance is implemented according to the following steps:

[0024] 1. Put the wood in the lumen of the plasma cleaner, evacuate the lumen to a vacuum, inject argon gas, turn on the power and perform plasma cleaning in the glow state to obtain the cleaned wood;

[0025] 2. Put the cleaned wood into the magnetron sputtering apparatus, pump it into a vacuum, and then introduce oxygen, turn on the radio frequency power supply with titanium element, and pre-sputter for 1 to 2 minutes to obtain pre-sputtered wood;

[0026] 3. After the glow of titanium elemental substance is oxidized into titanium dioxide ions, open the cover door of the magnetron sputtering target head, firstly in a vacuum of 8.3×10 -6 MPa~1.0×10 -5 MPa, the power is 300-400W, the oxygen flow rate is 5-7sccm, and the argon flow rate is 9-13sccm, and the particle sputtering treatment is carried o...

specific Embodiment approach 2

[0029] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the wood described in step one is poplar, larch, sylvestris pine, ash, rubber wood or bamboo. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0030] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the purity of the oxygen in step 2 is greater than 99.99%. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention provides a pollution-free treatment method for improving the weathering resistance and the amphiphobic performance of wood, relates to a wood surface treatment method, and solves the problem that a conventional method for improving the weathering resistance and the amphiphobic performance of wood is long in using period, and organic raw materials have toxicity. The treatment method comprises the following steps that 1, plasma cleaning is conducted on the wood; 2, the cleaned wood is placed in a magnetron sputtering apparatus for pre-sputtering; 3, oxygen and argon are introduced, after elemental titanium is oxidized into titanium dioxide ions in the glow state, the wood is sputtered at the power of 300-400 W, the power is adjusted to 100-150 W, and ion sputtering treatment is continued to obtain wood sputtered with a titanium dioxide layer; and 4, the sputtered wood is soaked in an octadecyltrichlorosilane solution, and the soaked wood is dried finally. The sputtering material, namely elemental titanium, is nontoxic, the whole sputtering treatment time is shortened greatly, and the weathering resistance treatment efficiency of the wood is improved.

Description

technical field [0001] The invention relates to a treatment method for improving wood weather resistance, antibacterial performance and amphiphobic performance. Background technique [0002] Wood is exposed to the outdoor natural environment, and it is subjected to photochemical degradation of ultraviolet rays, leaching of rainwater, hydrolysis, swelling and shrinkage, erosion of wind load, and corrosion of microorganisms. The color changes first. Generally speaking, the original light-colored wood becomes slightly darker, and the darker-colored wood becomes slightly lighter, and the color of the wood surface gradually becomes gray. The usual treatment method takes a long time, generally takes 2 to 3 days, and may even take a week. The chemical reagents used are mostly polluted and uneven, and most of them need to be dried. During the drying process, the wood may crack and other phenomena. The surface of wood is easy to absorb liquids such as water and oil, which makes the ...
