Embodiment 1

[0017] A kind of preparation method of outdoor anticorrosive bamboo board, comprises the following steps:

[0018] (1) After cutting, removing knots, and removing bamboo green and bamboo yellow, the collected fresh bamboo is vertically cut into long strips of bamboo, and heat-preserved in boric acid aqueous solution with a mass concentration of 2.5% at a temperature of 90°C for 30 minutes. The pulse current is continuously applied, and the intermediate material is obtained after the treatment is completed;

[0019] (2) Dry the intermediate material in a relatively closed drying warehouse. There is a hollowed-out shelf in the drying warehouse. Carbon dioxide, after continuing to feed for 15 minutes, obtains dry material;

[0020] (3) Treat the dry material in the carbonization chamber. The treatment includes two stages. The temperature of the first stage is 130°C, the humidity is 43%, and the processing time is 35 minutes; the temperature of the second stage is 210°C, and the ...

Embodiment 2

[0025] A kind of preparation method of outdoor anticorrosive bamboo board, comprises the following steps:

[0026] (1) After cutting, removing knots, and removing bamboo green and bamboo yellow, the collected fresh bamboo is vertically cut into long strips of bamboo, and heat-preserved in boric acid aqueous solution with a mass concentration of 2.8% at a temperature of 85°C for 20 minutes. The pulse current is continuously applied, and the intermediate material is obtained after the treatment is completed;

[0027] (2) Dry the intermediate material in a relatively closed drying warehouse. There is a hollowed-out shelf in the drying warehouse. After placing the intermediate material on the hollowed-out shelf, feed it with a temperature of 85°C at a flow rate of 40mL / min. Carbon dioxide, after continuing to feed for 10 minutes, obtains dry material;

[0028] (3) Treat the dry material in the carbonization chamber. The treatment includes two stages. The temperature of the first ...

Embodiment 3

[0033] A kind of preparation method of outdoor anticorrosive bamboo board, comprises the following steps:

[0034] (1) After cutting, removing knots, and removing bamboo green and bamboo yellow, the collected fresh bamboo is vertically cut into long strips of bamboo, and heat-preserved in boric acid aqueous solution with a mass concentration of 2.2% at a temperature of 95°C for 40 minutes. The pulse current is continuously applied, and the intermediate material is obtained after the treatment is completed;

[0035] (2) Dry the intermediate material in a relatively closed drying warehouse. There is a hollow shelf in the drying warehouse. After placing the intermediate material on the hollow shelf, feed it with a temperature of 75°C at a flow rate of 20mL / min. Carbon dioxide, after continuing to feed for 20 minutes, obtains dry material;

[0036] (3) Treat the dry material in the carbonization chamber. The treatment includes two stages. The temperature of the first stage is 140...

Abstract

The invention belongs to the technical field of anticorrosive bamboo plate processing, and specifically relates to a preparation method for an outdoor anticorrosive bamboo plate. The preparation method comprises the steps of carrying out impregnation treatment on acquired fresh bamboo materials, then drying the acquired fresh bamboo materials in an airtight environment, carrying out carbonizationtreatment, preparing a compound adhesive solution, and preparing the plate. Compared with the prior art, the preparation method has the following advantages: a boric acid aqueous solution or a boric acid aqueous solution containing ammonium polyphosphate is utilized for carrying out treatment under the action of a pulse current, so that the treatment time is greatly shortened, and anticorrosive and mold-proof effects in the strip bamboo materials are also achieved; and high-temperature carbon dioxide is utilized for drying intermediate materials, and then impregnation is carried out in the compound adhesive solution, so that the adhesive impregnation quality is ensured, the obtained bamboo plate is stable in quality and high in density, and has high water-resistant, anti-insect, mold-proofand weather-proof effects, the service life of the bamboo plate reaches 10 years and above in the case of being laid outdoors, and the mechanical property and the mold-proof effect of the bamboo plate cannot be influenced even if screws are used, so that the use range of the bamboo plate is expanded.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion bamboo board processing, and in particular relates to a preparation method of an outdoor anti-corrosion bamboo board. Background technique [0002] Bamboo products are widely used in people's daily life. Compared with wood, which can be used for decades or even hundreds of years, bamboo can be felled and used in 4-7 years without damaging the ecological environment. It is in line with the current international environmental protection concept of low-carbon environmental protection. Outdoor anti-corrosion bamboo boards are usually used in parks, scenic spots, and plank roads. They make full use of the stable structure of bamboo fiber materials to ensure the high utilization rate of bamboo and the original physical and mechanical properties. The existing bamboo products are generally anti-corrosion in bamboo The surface is anti-mildew and anti-corrosion treatment, the effect of the drug is on...
