Embodiment 1

[0031] The steps of manufacturing lightweight outdoor recombined bamboo landscape materials are as follows:

[0032] Raw material processing: 4-6 years old moso bamboo is used as raw material, cut into 2 meters long, remove the inner and outer bamboo joints, split into bamboo slices, the bamboo slices are 15-30mm wide, 2-5mm thick, remove green and yellow, and then cut each piece The bamboo flakes are sent to the bamboo flake rolling mill and rolled into bamboo flakes with vertical concave-convex dislocation arrangement and adjacent strands connected to each other. The width of each strand in the bamboo flakes is 1.5-4mm. %the following.

[0033] Put the above-mentioned bamboo shreds in the impregnation tank container, vacuumize to 0.04-0.06Mpa, and keep it for 15min; pump the modified chitosan metal composite preservative into the impregnation tank; pressurize the impregnation tank to 0.8 -1.0Mpa, keep the pressure for 40-50min, then reduce the pressure to 0.1-0.08Mpa and ke...

Embodiment 2

[0037] The steps of manufacturing lightweight outdoor recombined bamboo landscape materials are as follows:

[0038] Raw material processing: 5-year-old Moso bamboo is used as raw material, cut into 3-meter-long sections, remove the inner and outer bamboo joints, and split into bamboo slices. The bamboo slices are 15-30mm wide and 2-5mm thick. Feed into the bamboo flake rolling mill and roll into bamboo flakes with longitudinal concave-convex dislocation arrangement and adjacent strands connected. The width of each strand in the bamboo flakes is 1.5-4mm, and the bamboo flakes are dried to a moisture content of less than 8%. .

[0039] Put the above-mentioned bamboo shreds in the impregnation tank container, vacuumize to 0.04-0.06Mpa, and keep it for 15min; pump the modified chitosan metal composite preservative into the impregnation tank; pressurize the impregnation tank to 0.8 -1.0Mpa, keep the pressure for 40-50min, then reduce the pressure to 0.1-0.08Mpa and keep it for 20...

Abstract

The invention belongs to landscape materials, and discloses a method for manufacturing a light outdoor recombination bamboo landscape material. The conventional outdoor recombination bamboo material has unstable product quality, low weather resistance and short service life and is easy to deform and mildew. The method comprises the following steps of: cutting off bamboo; removing green and yellow; rolling to obtain bamboo filaments; drying until moisture content is less than 8 percent; putting the bamboo filaments into an impregnation tank; vacuumizing and keeping the vacuum state for 12 to 15 minutes; sucking a modified chitosan metal complex preservative into the impregnation tank; increasing the pressure to be between 0.8 and 1.0MPa, and keeping the pressure for 40 to 50 minutes; reducing the pressure to be between 0.1 and 0.08MPa, and keeping the pressure for 20 minutes; taking the bamboo filaments out; drying at a low temperature until the moisture content is 8 to 10 percent; soaking in a modified adhesive; drying until the moisture content is 15 to 18 percent; spraying a polyurethane adhesive; combining blanks by using a mould; and hot-pressing and foaming to obtain the material. The method has the advantages that: a product does not deform due to high stability, and has long service life due to high rot resistance; and the weather resistance of the product is improved, so that the product is suitable to be used as the outdoor landscape material.

Description

technical field [0001] The invention belongs to landscape materials, in particular to a manufacturing method of lightweight outdoor recombined bamboo landscape materials. Background technique [0002] Wood has important applications in the construction industry and people's living utensils. Wood is also widely used as a decorative material, such as guardrails in parks and outdoor stairs. Due to the long growth cycle of wood, the supply of wood is very tight. my country currently consumes 250 million cubic meters of wood annually, and it still needs to spend 3 billion yuan to import wood and forest products to supplement the shortage of wood production. The shortage of timber resources has had an increasing impact on social and economic development, as well as on the environment and climate. Therefore, the development of wood substitute materials is a very urgent task. Bamboo is a product of nature. Bamboo has the advantages of high resistance, strong hardness, and good s...
