Background
The wood material has beautiful color and texture, excellent humidity regulation and mechanical property, is a key material for developing sustainable ecological buildings, and is applied to the fields of indoor decoration, furniture and the like. However, wood is rich in polysaccharides (e.g., starch), minerals (e.g., mg, fe, ca), vitamins, proteins, etc., resulting in wood that is susceptible to mold attack in humid environments. The mould can not only affect the color texture of the wood elements, but also threaten the physical health of people. Therefore, it is important to enhance the mold resistance of wood.
At present, the wood mildew preventive measures comprise: physical barrier, bactericide filling, chemical denaturation, and the like. The physical barrier can obviously increase the mildew-proof effect of the wood, but the conventional coating materials (such as paraffin and red paint) lack bonding effect with the wood, so that the barrier layer is easy to fall off. Commonly used biocides are water soluble materials that are susceptible to attack by liquid water resulting in failure. In addition, the bactericide contains volatile organic compounds, fluorine, chromium, arsenic and other toxic elements, and thus, the bactericide poses potential threats to human health. Modification technologies such as carbonization can decompose the nutrient substances contained in the wood, reduce the moisture absorption performance of the wood, and thus increase the mildew resistance of the wood. But the carbonization cost is high, the process is complex, uniform carbonization is not easy to realize, and the processing of whole wood is not utilized.
Therefore, it is necessary to develop a new technology with remarkable mildew-proof effect, stable performance, low price and simple processing mode.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Example 1:
the preparation method of the mildew-proof wood composite material comprises the following steps:
s1, surface modification of a wood material: soaking Barbados into a mixture of 2.5M sodium hydroxide and 0.4M sodium sulfite, standing for 6h, and soaking at 100 deg.C for 12h, and named as DW;
s2, soaking the pretreated batten in 500ml of water, then adding 100g of acrylamide, 100ml of glycerol and 50g of boric acid, and stirring at room temperature for 6 hours to obtain a polymer hydrogel precursor solution;
s3, adding 0.4g of potassium persulfate and 1.0ml of N, N, N, N-tetramethylethylenediamine into the polymer hydrogel precursor solution obtained in the step S2, and stirring for several minutes;
s4, ageing of the wood composite material: and (3) transferring the wood into a heat preservation box, setting the temperature to be 60 ℃ and the heat preservation time to be 12h, and fully polymerizing acrylamide to obtain the mildew-proof wood composite material named as DW/PAM/BH.
Comparative example 1:
this comparative example is based on example 1 and differs from example 1 in that:
the polymer hydrogel precursor solution does not contain boric acid, other modification steps are completely the same as chemical components, and the composite wood prepared by the comparative example is named as DW/PAM.
The mildewproof wood composite prepared in example 1 was subjected to material characterization and testing:
1) And carrying out field emission scanning electron microscope (FE-SEM) tests on the original Barsha Wood (BW) and DW/PAM/BH composite materials. As shown in fig. 1, 2, the original balsa wood exhibits a closed cell structure, while the dried DW/PAM samples exhibited dense characteristics, meaning that the polymer hydrogel had been fully packed in the cellulose network. As can be seen from fig. 3, boric acid is uniformly distributed in the wood.
2) The original Barsha Wood (BW) and DW/PAM/BH samples are subjected to mildew resistance tests, and the specific test process is as follows: after being placed in a high-humidity environment of 90% for 180 days, as shown in fig. 4 and 5, as can be seen from fig. 4 and 5, when being placed in a high-humidity environment of 90% for 180 days, no mold is observed on the surface of the composite material (DW/PAM/BH), and a 100% bacteriostasis rate is still shown; and mould is observed on the surface of the original Balsawood (BW), and the bacteriostatic effect is poor.
Example 2:
study of the mildew-resistant effect of the polymer hydrogel:
the formulations of the polymer hydrogel containing boric acid and the polymer hydrogel without boric acid were the same as in example 1, and the polymer hydrogel without boric acid was the formulation of example 1 with boric acid excluded.
The mold-proofing effects of both are shown in fig. 6:
the polymer hydrogel (PAM) without boric acid (antimicrobial) added had no bacteriostatic effect; the polymer hydrogel (PAM/BH) added with the boric acid presents an obvious bacteriostatic ring, which indicates that the boric acid slowly released by the hydrogel can effectively sterilize.
Example 3:
the influence of the polymer hydrogel on the mildew resistance of materials of different materials is researched. This example is based on example 1, and differs from example 1 in that: the original materials are different in type, and other modification technologies are completely the same. In this example, the comparison between the original wood of the red willow, the balsa wood and the bamboo wood and the mildewproof wood composite material treated by the preparation method of the example 1 is compared, and the result is shown in fig. 7, and as can be seen from fig. 7, the polymer hydrogel has efficient mildewproof performance and has no requirements on the types of the materials.
In addition, after the unmodified bamboo was left in a humid environment for 30 days, as shown in fig. 8, penicillium, mucor, aspergillus niger, aspergillus flavus, etc. were observed, but no mold was observed on the surface of the modified bamboo.
Example 4:
this example investigates the effect of different fungicides on the mildew resistance of wood. The present example is based on example 1, and differs from example 1 in that: the sterilization material is quaternary ammonium salt, and other modification technologies are completely the same. As can be seen from fig. 9, the quaternary ammonium salt modified wood (balsa wood composite) was soaked in clear water for 15 days and then placed in a humid environment for 180 days, and no mold was observed on the surface of the material; while mould was observed on the surface of untreated virgin wood (balsa).
In conclusion, the wood composite material prepared by the method shows a surprising mildew-proof effect: the antibacterial agent has obvious inhibition on penicillium, mucor, aspergillus niger, aspergillus flavus and other fungi; even if the composite material is stored for 180 days in a high-humidity environment of 90%, the original color and luster texture of the composite material is kept, and the antibacterial rate reaches 100%.
The above-mentioned embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned embodiments are only examples of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
