Preparation method for outdoor anticorrosive bamboo plate

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...

[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 destroying 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, making full use of the stable structure of bamboo fiber materials to ensure high utilization of bamboo materials and original physical and mechanical properties. The surface is anti-mildew and anti-corrosion treatment, the effect of the drug is only 2mm away from the surface layer, but in actual use, it is necessary to fix the bamboo with screws and other materials, which may damage the bamboo board. Mildew and rot will still occur in a humid environment. Therefore, it is a technical problem to be solved on the basis of how to improve the mechanical properties of bamboo boards.
