Mouldproof and mothproof treatment method for wood

Abstract

The invention relates to a mouldproof and mothproof treatment method for wood. The mouldproof and mothproof treatment method comprises the following steps: (1) processing wood at 85-90 DE C for 3 hours under the condition that the relative humidity is 48%-50%; (2) fumigating the wood with a 35% acetate solution at 1-1.5MPa and 105 DEG C for 30-45 minutes; (3) preparing a treating fluid; (4) soaking the wood treated in the step (2) with the treating fluid at 35 DEG C for 2 hours; (5) treating the wood surface treated in the step (4) with quick lime; and (6) treating the wood processed in the step (5) at 78 DEG C for 3 hours under the condition that the relative humidity is 25%-38%. The mouldproof and mothproof treatment method for the wood provided by the invention is simple; heavy metal is not used in the treatment process; no components which pollute a human body or the environment are generated after treatment; pollution is avoided; meanwhile, the treatment time is shortened to a few hours; and the treatment efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of wood processing, and in particular relates to a mildew-proof and insect-proof treatment method for wood. Background technique [0002] Wood is an important raw material in production and life. It can be seen everywhere from tables, chairs, benches to ship decks. The amount of wood used is too good, but wood also has great defects. It is easy to be corroded by mildew and insects, causing wood damage. Corrosion affects the normal use. Nowadays, many wood anti-mildew and anti-insect treatments are treated with heavy metal solutions or painted with paint. Although they also have good anti-mildew and anti-insect effects, heavy metals and other treatments often have toxic residues. It will affect people's health when used in areas that are in contact with people. At present, some natural antifungal agents are used for treatment, but the treatment cycle is long, and it often takes several days or dozens of days to achieve...
