Problems solved by technology

How to improve the antiseptic performance of wood is a technical problem that needs to be solved in the prior art. Most of the treatments for improving the antiseptic performance of wood in the prior art are treated with bacteriostatic agents to improve the antiseptic performance of wood. However, existing The bacteriostatic agent of this application can also produce health threats to the contacts while improving the wood preservative performance, which does not conform to the green technology.
[0003] Cinnamaldehyde has good antibacterial and antiseptic properties, so it is widely used. However, the duration of antibacterial is short, and the loss rate of antibacterial effect on wood after treatment is relatively high.

Embodiment 1

[0017] A treatment process that uses cinnamaldehyde derivatives to improve the preservative properties of wood. The cinnamaldehyde derivatives are mixed with deionized water to prepare a 3.5% cinnamaldehyde derivative solution, and then the quality is added to the cinnamaldehyde derivative solution 0.12% of nano-zinc oxide particles, then ultrasonic treatment for 3 minutes to obtain a premix, soak the wood in the premix, soak for 5min at room temperature, and then add 10% binaphthol dropwise to the premix Solution, the dropwise amount of the binaphthol solution is 20% of the volume of the premix. After the addition is completed, the premix and the wood are transferred into a vacuum reactor, and vacuum immersion treatment is carried out at 75°C for 10 minutes, and then taken out. Clean the surface with deionized water, and then drain it naturally.

[0018] Further, the preparation method of the cinnamaldehyde derivative is:

[0019] (1) Dissolve 0.0035mol threonine and 0.0035mol so...

Embodiment 2

[0027] A treatment process that uses cinnamaldehyde derivatives to improve the preservative performance of wood. The cinnamaldehyde derivatives are mixed with deionized water to prepare a 4.5% cinnamaldehyde derivative solution, and then the quality is added to the cinnamaldehyde derivative solution 0.16% of nano-zinc oxide particles are then treated with ultrasonic for 5 minutes to obtain a premix. The wood is soaked in the premix for 10 minutes at room temperature, and then 10-15% of the mass fraction is added dropwise to the premix. Naphthol solution, the drop amount of the binaphthol solution is 30% of the volume of the premix. After the dripping is completed, the premix and the wood are transferred into a vacuum reactor, and vacuum immersion treatment is carried out at 80°C for 15 minutes, and then taken out , Use deionized water for surface cleaning, and then drain naturally.

[0028] Further, the preparation method of the cinnamaldehyde derivative is:

[0029] (1) Dissolve ...

Embodiment 3

[0037] A treatment process that uses cinnamaldehyde derivatives to improve the preservative properties of wood. The cinnamaldehyde derivatives are mixed with deionized water to prepare a 4.0% cinnamaldehyde derivative solution, and then the quality is added to the cinnamaldehyde derivative solution 0.13% of nano-zinc oxide particles, then ultrasonic treatment for 4min to obtain a premixed solution, soak the wood in the premixed solution, soak for 8min at room temperature, and then dropwise add 12% binaphthol to the premixed solution Solution, the dropwise amount of the binaphthol solution is 25% of the volume of the premix. After the addition is completed, the premix and the wood are transferred into a vacuum reactor, and vacuum immersion treatment is carried out at 78°C for 12 minutes, and then taken out. Clean the surface with deionized water, and then drain it naturally.

[0038] Further, the preparation method of the cinnamaldehyde derivative is:

[0039] (1) Dissolve 0.0035mo...

Abstract

The invention discloses a treating technology for improving the wood anti-corrosion property through cinnamyl aldehyde derivatives and relates to the technical field of wood treatment. The cinnamyl aldehyde derivatives and deionized water are mixed to prepare a cinnamyl aldehyde derivative solution, then nanometer zinc oxide particles are added into the cinnamyl aldehyde derivative solution, and then through ultrasonic treatment, a pre-mixed solution is obtained; wood is soaked in the pre-mixed solution, under the normal temperature, soaking is conducted, then a binaphthol solution is added into the pre-mixed solution drop by drop, after drop-by-drop adding is completed, the pre-mixed solution and the wood are transferred into a vacuum reaction kettle, and vacuum soaking treatment is conducted; and then the wood is taken out, deionized water is adopted to conduct surface cleaning, and then natural draining is conducted. After the wood is treated through the treating technology, the remarkable inhibiting effect is achieved on fungi and mould.

Description

Technical field [0001] The invention belongs to the technical field of wood treatment, and specifically relates to a treatment process for improving the anticorrosive performance of wood by adopting cinnamaldehyde derivatives. Background technique [0002] Wood products, especially wooden handicrafts, are more and more widely used in daily life. Wood is a natural organic material with obvious biological characteristics and is easily attacked by organisms such as bacteria, insects, and marine borers. How to improve the anti-corrosion performance of wood is a technical problem that needs to be solved in the prior art. In the prior art, most of the treatments for improving the anti-corrosion performance of wood are treated with antibacterial agents to improve the anti-corrosion performance of wood. However, the existing The bacteriostatic agent in this application will not only improve the anti-corrosion performance of wood, but also pose a health threat to the contacts, which does ...
