specific Embodiment approach 1

[0033] Specific Embodiment 1: The preparation method of superhydrophobic, oleophobic, bactericidal, flame-retardant, weather-resistant and magnetic functional wood in this embodiment is carried out according to the following steps:

[0034] 1. Configuration of magnetic precursor liquid:

[0035] Weigh 1-5 parts of ferrous salt, 5-10 parts of ferric salt and 85-96 parts of deionized water according to the parts by mass, stir and dissolve to form a uniform solution, and obtain the magnetic precursor;

[0036] Two, wood magnetic treatment:

[0037] ①Add wood to the magnetic precursor solution obtained in step 1, and stir at room temperature for 1-5 hours; ②Add ammonia water dropwise to the magnetic precursor solution containing wood, adjust the pH to 9.5-10.5, and continue stirring for 1 hour; ③Take out the wood and place Wash it in distilled water until it is neutral, and leave it in the air for 1 hour at room temperature to complete the wood magnetic Fe 3 o 4 deal with;

Abstract

The invention discloses a preparation method of a superhydrophobic and oleophobic bactericidal flame-retardant weatherproof magnetic functional wood, relates to a preparation method of a functional wood and aims at solving the problems of high modifying agent toxicity, special peculiar smell, poor leaching resistance, environment pollution, complex operation process, high cost and single function of the existing wood modifying method. The preparation method comprises the steps of firstly, preparing a magnetic precursor liquid; secondly, carrying out magnetic treatment on a wood; thirdly, preparing a superhydrophobic and oleophobic bactericidal flame-retardant weatherproof multifunctional liquid; and fourthly, carrying out multifunctional treatment on the magnetic wood. The preparation method is simple in operation, environment-friendly and low in cost, is integrated with super-waterproof, oil-proof, bactericidal, mildew-proof, flame-retardant, weatherproof and magnetic properties and is used in the field of wood modification.

Description

technical field [0001] The invention relates to a preparation method of functional wood. Background technique [0002] Because of its unique composition and honeycomb porous structure, wood is prone to swelling and deformation caused by water absorption, cracking and warping caused by water decomposition, decay and degradation caused by mold erosion, and photothermal degradation caused by fire and weather. In order to extend the service life of wood and improve its waterproof, anti-corrosion, weather resistance, flame retardant and other durability, people modify natural wood. The existing methods for wood modification are as follows: 1. Using vinyl monolith The wood can be treated with polymers formed from monomers or heterocyclic polymerizable monomers, which can improve the mechanical properties of the wood and partially improve the durability, but the modifiers used in this method are either highly toxic or release gas later or cause high brittleness of the wood, and Th...
