Anti-corrosion recombined composite bamboo material and manufacturing method thereof

Abstract

The invention discloses an anti-corrosion recombined composite bamboo material and a manufacturing method thereof. The anti-corrosion recombined composite bamboo material is manufactured by utilizing bamboo as a main raw material, the density of the anti-corrosion recombined composite bamboo material is 0.9-1.50g / cm<3> and the water-absorbing thickness expansion ratio in the thickness direction and width direction of the anti-corrosion recombined composite bamboo material is respectively less than 1.5%; the anti-corrosion recombined composite bamboo material achieves a strong anti-corrosion level and has a bacterium damaged degree of zero level. The manufacturing method comprises the following steps: processing raw bamboo into bamboo strips, and then rolling the bamboo strips to obtain defibered bamboo bundles; digesting the defibered bamboo bundles by use of a dilute base solution and water sequentially, drying the bamboo bundles, and performing high-pressure transfusing on the bamboo bundles by use of a mixed aqueous solution of nano zinc oxide and bamboo mildew remover; then performing oxygen-exclusion drying treatment, high-temperature treatment and humidifying treatment; performing gumming, drying, curtain weaving, cold pressing and sizing, thermosetting and cooling equalization treatment, so as to obtain the anti-corrosion recombined composite bamboo material. The anti-corrosion recombined composite bamboo material has the advantages of corrosion resistance, weather resistance, insect prevention and good dimensional stability, and can be used for outdoor decoration.

Description

technical field [0001] The invention belongs to the technical field of bamboo modification and artificial board manufacturing in the bamboo industry, and in particular relates to an anti-corrosion recombined composite bamboo and a manufacturing method thereof. Background technique [0002] my country's bamboo forest area, stock volume and bamboo industry output value all rank first in the world, known as the "Kingdom of Bamboo". According to statistics, my country's existing bamboo forest area is about 7.2 million hm 2 , of which Moso bamboo accounts for about 70%. At the same time, my country is also the world's largest exporter of bamboo products, both in terms of quantity and quality of bamboo products, ranking first in the world. Bamboo has the advantages of high strength, good toughness, and high hardness, and is an excellent raw material for manufacturing recombinant composite materials. However, because bamboo itself contains more nutrients than ordinary wood, it i...

Problems solved by technology

However, because bamboo itself contains more nutrients than ordinary wood, it is easy to rot, mildew and insects under warm and humid conditions, which not only affects the aesthetics of bamboo products, but also shortens the service life of bamboo. Meet the market's demand for aesthetics and functionality of bamboo products, especially, it is more difficult to use in harsh outdoor environments
