Embodiment 1

[0039] A kind of treatment method of bamboo wood mildew-proof and anticorrosion of the present invention:

[0040] Slowly add a certain amount of ethyl orthosilicate to the aminopropyltriethoxysilane solution, while stirring the solution, and then add an appropriate amount of absolute ethanol, in which ethyl orthosilicate, aminopropyltriethoxy The volume ratio of silane and absolute ethanol is 5:0.5:2. Use dilute hydrochloric acid to adjust the pH to 3~4, stir well until the mixture has no suspended matter, and make a uniform sol. Put the bamboo wood sample into the impregnation tank, pour the sol, press the sample with a heavy object to avoid floating of the sample, vacuumize, control the vacuum pressure at -0.06Mpa, keep the pressure for 50min, and then release the pressure. Pressurize the impregnation tank to 2MPa, keep the pressure for 80min, then release the pressure, take out the bamboo wood sample, clean the surface of the sample and empty the impregnation tank. Put t...

[0043] A kind of treatment method of bamboo wood mildew-proof and anticorrosion of the present invention:

[0044]Slowly add a certain amount of sodium silicate aqueous solution into the aminoethylaminopropylmethyldimethoxysilane solution, while stirring the solution, and then add an appropriate amount of absolute ethanol, wherein sodium silicate aqueous solution, aminoethylammonia The volume ratio of propylmethyldimethoxysilane and absolute ethanol is 10:1:6. Use glacial acetic acid to adjust the pH to 3~4, stir well until the mixture has no suspended matter, and make a uniform sol. Put the bamboo sample into the impregnation tank, pour the sol, press the sample with a heavy object to avoid floating of the sample, vacuumize, control the vacuum pressure at -0.08Mpa, keep the pressure for 100min, and then release the pressure. Then pressurize the dipping tank to 5MPa, keep the pressure for 160min, then release the pressure, take out the bamboo wood sample, clean up the surface...

Embodiment 3

[0047] A kind of treatment method of bamboo wood mildew-proof and anticorrosion of the present invention:

[0048] Slowly add a certain amount of n-butyl titanate into the 3-aminopropyltriethoxysilane solution, while stirring the solution, and then add an appropriate amount of absolute ethanol, in which n-butyl titanate, 3-aminopropyl The volume ratio of triethoxysilane and absolute ethanol is 15:2.5:10. Use dilute hydrochloric acid to adjust the pH to 3~4, stir well until the mixture has no suspended matter, and make a uniform sol. Put the bamboo wood sample into the impregnation tank, pour in the sol, press the sample with a heavy object to avoid floating of the sample, vacuumize, control the vacuum pressure at -0.098Mpa, keep the pressure for 150min, and then release the pressure. Pressurize the dipping tank to 7MPa and keep the pressure for 240min. Then the pressure is released, the bamboo wood sample is taken out, the surface of the sample is cleaned and the impregnatio...

Abstract

The invention discloses a treatment method of a bamboo wood anti-mold preservative. The specific steps include: putting a bamboo wood sample into a dipping tank, pouring in the anti-mold anti-corrosion agent, and vacuuming, and controlling the vacuum pressure to -0.06~-0.098Mpa , the holding time is 50~150min, and then pressurize after decompression, the pressurized pressure is controlled at 2~7MPa, and the holding time is 80~240min; or put the bamboo wood sample into the impregnation tank, vacuumize, The vacuum pressure is controlled at ‑0.06~‑0.098Mpa, and the holding time is 50~150min. After the pressure is released, the anti-mildew preservative is poured in, and then pressurized. The pressurization pressure is controlled at 2~7MPa, and the holding time is 80~ 240min. The bamboo wood anti-mildew preservative of the invention has a simple treatment method, and the treated bamboo wood has high durability and excellent anti-loss performance.

Description

technical field [0001] The invention relates to a treatment method for an anti-mold preservative, in particular to a treatment method for anti-mold and anti-corrosion of bamboo wood. Background technique [0002] With the increasing scarcity of timber resources in our country, bamboo and timber resources, which are rich in resources, short in production cycle and renewable, are becoming an important source of wood raw materials. However, because bamboo wood is rich in nutrients such as sugar, starch, protein and fat, it is easy to produce mildew, discoloration, insects and decay during storage, transportation and use, which affects the quality of bamboo wood. processing and utilization, and even cause great economic losses. Therefore, the anti-mold and anti-corrosion treatment of bamboo wood has become an indispensable link in the industrial utilization of bamboo wood, and is very important for the sustainable utilization of bamboo wood resources. [0003] Anti-mold and an...
