The performance tests of the waterproof wooden packing box material modified by the nano diatomite obtained in the example 5 and the waterproof wooden packing box materials obtained in the comparative examples 1-2 are as follows:
I. water content and water absorption
Determining the water content of the waterproof wooden packing box material according to a GB/T1931-; the water absorption rates of the waterproof wooden packing box material for 6h and 24h were measured according to GB/T1934.1-2009 method for measuring water absorption of wood, and the results are shown below:
| water content% | Water absorption of 6 h% | 24h water absorption% | |
| Example 5 | 7.5 | 45.1 | 63.5 |
| Comparative example 1 | 10.6 | 62.7 | 87.8 |
| Comparative example 2 | 9.3 | 53.8 | 72.0 |
The above results show that: the waterproof wooden packing box material treated by the method has excellent waterproof performance, and can obviously reduce the moisture content and the water absorption of wood.
II. Contact angle
Carrying out oven drying treatment on the waterproof wooden packing box material; then, the contact angle of each wood with water (deionized water, 2. mu.L per water drop) on three sections (cross section, chord section, and diametral section) was measured using a wood contact angle measuring instrument (OCA 20 model, Dataphysics, Germany).
The contact angle of the wood surface is measured by adopting a dynamic contact angle measuring method, the contact angle value of a water drop on the wood surface after 5 seconds of balance is selected, and the measurement result is shown as follows:
| cross section, degree | Tangent plane of the string, degree | Radial section, degree | |
| Example 5 | 164.3 | 161.4 | 159.7 |
| Comparative example 1 | 139.5 | 124.6 | 130.3 |
| Comparative example 2 | 148.7 | 145.8 | 142.1 |
The above results show that: the contact angle between the three sections of the waterproof wooden packing box material treated by the method disclosed by the invention and water is obviously improved.
The contact angle of the water drop on the wood surface after 5 seconds of balance is because the wood surface after the water repellent treatment has strong hydrophobicity or the super-hydrophobicity contact angle value of more than 150 degrees, and the water drop can stably keep the spherical state of the water drop on the water repellent treated wood surface. When the surface of the treated material is inclined at a certain angle from a horizontal state, water drops can roll off from the inclined surface of the wood instead of penetrating into the wood, so that the high contact angle value shows that the treated wood has excellent hydrophobicity and a good waterproof effect.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
