Embodiment 1

[0013] (1) Saw the board into a certain specification, polish the surface of the board, wash it with distilled water, and dry it in a blast drying oven at 120 °C to constant weight;

[0014] (2) The JGP450A2 magnetron sputtering system was used to prepare the carbon nitride protective layer on the wood surface. Using graphite phase carbon nitride as the target material, before sputtering, put the wooden board in step (1) into the sputtering chamber, and use mechanical pump and molecular pump to evacuate, when the background pressure of the vacuum chamber is less than 1.0×10 -4 Pa, first use high-purity argon to pre-sputter the target itself for 5 minutes to clean the surface of the target, then introduce high-purity nitrogen, and through the adjustment of the gate valve, when the working pressure in the vacuum chamber reaches 0.4 Pa , start the sputtering deposition of carbon nitride film, the sputtering power is 100 W, and the deposition time is 5 h. The surface contact ang...

Abstract

The invention provides a method for growing a carbon nitride protective layer on a wood surface. By using a wood board (fir wood, pine wood or the like) as the research object and graphite-phase carbon nitride as a target, a spattering process is performed to grow a carbon nitride protective layer on the wood surface. The prepared wood, the surface of which the carbon nitride protective layer is grown, has the advantages of favorable hydrophobicity, favorable wear resistance, favorable corrosion resistance, favorable weather resistance and favorable dimensional stability, and has favorable function of purifying volatile organic compounds in air. The method is convenient and simple in technique, and has obvious economic and social benefits.

Description

technical field [0001] The invention belongs to the field of wood surface treatment, in particular to a method for growing a carbon nitride protective layer on the wood surface. Background technique [0002] With the rapid development of my country's economy, the country's urban construction is advancing by leaps and bounds, and people's requirements for production and living environment beautification are constantly increasing. Wood, known as "ancient and evergreen, traditional and trendy" building material, is deeply loved by people. favor. Many buildings, museums, tourist areas, parks, etc. are constructed or decorated with wood. Therefore, the demand for wood products is increasing. In order to alleviate the contradiction between supply and demand of wood, the country has vigorously developed the plantation of artificial fast-growing forests. However, artificial fast-growing forest wood generally has shortcomings such as soft material, easy to burn, low hardness, poor w...
