Abstract

The invention discloses a preparing method for undersized-log reconstructing outdoor furniture wood. The preparing method comprises the steps that (1), fresh vitex negundo stems with the diameter smaller than 4 CM are cut into segments, the length of each segment ranges from 35 cm to 45 cm, the segments are ground three times, bark is removed, the segments are dried at the temperature of 105 DEG C for 10 h to 15 h, and vitex negundo wood bunches are obtained, wherein the rotating speed of a rolling machine ranges from 25 r / min to 35 r / min, and the linear pressure ranges from 15 N / mm to 20 N / mm; (2), a phenolic resin solution is diluted according to the volume ratio of the phenolic resin solution to water being 55-65:35-45, an enhancement solution is obtained, the vitex negundo wood bunches are soaked in the enhancement solution for 30 h to 35 h at the normal temperature and under the normal pressure according to the volume ratio of the vitex negundo wood bunches to the enhancement solution being 1:10-20, then the vitex negundo wood bunches are taken out and aired, the vitex negundo wood bunches are baked at the temperature ranging from 40 DEG C to 60 DEG C until the water content rate of the vitex negundo wood bunches ranges from 3% to 5%, and plastified vitex negundo wood bunches are obtained; and (3), the plastified vitex negundo wood bunches are immersed into the phenolic resin solution to be soaked for 90 s to 120 s, then the wood bunches are subject to draining, airing, aging, assembling and hot press molding, and the undersized-log reconstructing outdoor furniture wood is prepared. According to the preparing method, industrialization is easily achieved, and the prepared furniture wood has the mouldproof anti-corrosion properties.

Description

technical field [0001] The invention relates to a method for preparing furniture materials, in particular to a method for preparing small-diameter wood recombined outdoor furniture materials. Background technique [0002] Reconstituted wood is a new type of wood-based panel that is low-carbon, environmentally friendly, and low-quality materials can be reused. It has been vigorously developed recently. Traditional recombined wood uses 6-10 cm small-diameter fast-growing thinning timber, lumber-making residues, low-quality small-diameter wood, branch wood, etc., and is processed by rolling equipment into wood bundles that are not broken horizontally, loose longitudinally, and interlaced. , and then through the processes of drying, sizing, paving, pre-pressing and hot-pressing, the recombined wood board is finally made. On the basis of inheriting and absorbing the successful experience of traditional recombined wood and existing recombined bamboo and bamboo-based fiber composi...
