Embodiment 1

[0030] Embodiment 1: a kind of preparation method of anticorrosion recombined wood is carried out according to the following steps:

[0031] a. Wood (fast-growing poplar (P. × canadensis Moench): collected from Wen'an County, Hebei Province, 20 years old, diameter at breast height 25-35cm, air-dry density 0.33g / cm2 with rotary cutter 3 ) into veneers with a thickness of 7mm, and cut them, and then use a deflagging machine to decompose the veneers into long, cross-linked and network-like wood bundles that maintain the original arrangement of fibers, and dry to a moisture content of 9 %;

[0032] b. Immerse the wooden bundles in a copper azole preservative with a concentration of 0.25% to a drug loading of 1kg / m 3 , air-dried to a moisture content of 8% after impregnation;

[0033] c. Put the air-dried wood bundles into phenolic resin adhesive (solid content 48.06%, viscosity 72mPa·s (30°C)) for dipping, the dipping amount is 13% of the wood bundle mass fraction, after dipping...

[0035] Embodiment 2: a kind of preparation method of anticorrosion recombined wood is carried out according to the following steps:

[0036] a. Wood (fast-growing poplar (P. × canadensis Moench): collected from Wen'an County, Hebei Province, 20 years old, diameter at breast height 25-35cm, air-dry density 0.33g / cm2 with rotary cutter 3 ) into veneers with a thickness of 6 mm, and cut them, and then use a deflagging machine to decompose the veneers into long, interlinked and network-like wood bundles that maintain the original arrangement of fibers, and dry to a moisture content of 8 %;

[0037] b. Immerse the wood bundles in a copper azole preservative with a concentration of 0.28% to a drug loading of 1kg / m 3 , air-dried to a moisture content of 7% after impregnation;

[0038] c. Put the air-dried wood bundles into phenolic resin adhesive (solid content 48.06%, viscosity 72mPa·s (30°C)) for dipping, the dipping amount is 13% of the wood bundle mass fraction, after dipping ...

Embodiment 3

[0040] Embodiment 3: a kind of preparation method of anticorrosion recombined wood is carried out according to the following steps:

[0041] a. Wood (fast-growing poplar (P. × canadensis Moench): collected from Wen'an County, Hebei Province, 20 years old, diameter at breast height 25-35cm, air-dry density 0.33g / cm2 with rotary cutter 3 ) into veneers with a thickness of 5 mm, and cut them, and then use a deflagging machine to decompose the veneers into long, interlinked and network-like wood bundles that maintain the original arrangement of fibers, and dry to a moisture content of 7 %;

[0042] b. According to 21 parts of copper acetate, 55 parts of monoethanolamine, 10 parts of ammonia, 0.4 part of alcohol, 0.4 part of propiconazole, 5 parts of xylene, 3 parts of alkyl aryl polyoxyethylene ether, 40 parts of water are prepared according to conventional method to obtain copper azole preservative (the preparation of copper azole preservative is also can be used first Dissol...

Abstract

The invention discloses a preparation method of antiseptic composited wood. The preparation method comprises the following steps of 1, cutting wood into single boards in a rotary manner through a rotary cutter, conducting cutting, and then, defibering the single boards into network-state or bundle-state wood bundles through a defibrator; 2, putting the wood bundles into a copper azole antiseptic substance for soaking, and conducting air-drying after soaking; 3, putting the air bundles obtained after air-drying into phenolic resin adhesive for adhesive dipping, and conducting drying after adhesive dipping; and 4, conducting rift grain assembly on the dried wood bundles, putting the wood bundles into hot pressing equipment for hot pressing gluing, so that boards are formed and composited wood finished products are obtained. The antiseptic composited wood is excellent in corrosion resistance, size stability and mechanical performance; and in addition, the treatment mode of the copper azole antiseptic substance for soaking the composited wood and the composited wood hot pressing process are further optimized, and the corrosion resistance and mechanical performance of the composited wood are further improved.

Description

technical field [0001] The invention relates to a method for preparing antiseptic recombined wood, which belongs to the field of wood production. Background technique [0002] As an organic natural biopolymer material, wood is susceptible to erosion and damage by microorganisms and insects under suitable temperature and humidity conditions, resulting in the degradation of the three major elements of wood, thereby reducing the material and service life of wood. At present, the anticorrosion of wood is mainly to apply chemical agents to treat materials to prevent the damage of biological factors such as fungus and insects to materials, so that the average service life of materials can be extended to 5-6 times. Preservative treatment expands the range of outdoor applications of wood, allowing it to be used outdoors in environments that come into contact with soil, fresh water or sea water. [0003] Recombined wood is a high-strength biomass composite material with wood bundles...
