specific Embodiment approach 1
[0038] Specific embodiment one: the preparation method of wood superhydrophobic bactericidal and anti-mildew function modifier of the present embodiment, comprises the following steps:
[0039] 1. Weigh 1%-50% of hydrophobic polymer resin, 0.5%-5% of functional additives, 0.1%-1% of surfactant and the rest of the solvent according to mass percentage, and mix them at room temperature Stir for 0.1-1 hour to obtain functional reagent A;
[0040] 2. Weigh 0.1%-5% of nanoparticles, 0.1%-2% of modifier and the rest of toluene according to mass percentage, mix and stir for 72-76 hours, then wash with acetone, and then centrifuge at 8000-9000rpm 3-5 times, then dry at 78-82°C for 12-14 hours to obtain functional reagent B;
[0041] 3. Add functional reagent B to functional reagent A. The mass of functional reagent B is 0.1%-1% of the mass of functional reagent A. Ultrasound for at least 30 minutes to obtain the wood modifier.
specific Embodiment approach 2
[0042] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 1, the hydrophobic polymer resin is a fluorocarbon resin with less than 8 F atoms. Others are the same as in the first embodiment.
[0043] In this embodiment, the fluorocarbon resin is purchased from Shangmeng Technology Wuxi Co., Ltd., which meets the environmental protection standards of Europe, Japan and the United States.
specific Embodiment approach 3
[0044]Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: in step one, the functional auxiliary agent is a mixture composed of iodopropynyl butyl carbamate (IPBC) and benzimidazole in any proportion . Others are the same as in the first or second embodiment.
