Embodiment 1
[0033] 1. Weigh 100 parts by weight of absolute ethanol under normal temperature and pressure, and add 1.1 parts by weight of 3-aminopropyltriethoxysilane to the base liquid as the base liquid of the metal-complex silicone gel hydrophobic fungicide Coupling agent and 0.17 parts by weight of copper chloride; Stir at a constant speed for 30 minutes; Continue to add 10 parts by weight of methyltriethoxysilane to stir; Then use glacial acetic acid to adjust the pH of the solution and stir for 2 hours to obtain mildew-proof and anti-corrosion agent.
[0034] 2. Put the prepared wood into a beaker with anti-mildew preservative and stir for 24 hours, then place it in the air to dry for 30 minutes; then soak the wood in the anti-mildew preservative for 5 minutes, air dry for 30 minutes, and cycle this step 5 times ; After drying the wood in an oven at 103°C for 24 hours, place it at room temperature for 3 days to obtain the wood treated with the anti-mold preservative.
