Abstract
The invention provides a preservation method of woods. The method comprises the following steps of (1) putting a wood material in a closed pressure impregnation tank, and adding the wood antiseptic until the tank is full; (2) pressurizing to a pressure of 0.8+/-0.05MPa, and keeping for 110 hours; (3) releasing the pressure and evacuating the antiseptic; and (4) taking the wood material from the tank. The preservative does not contain arsenic, chromium and other substances, is low in toxicity, and has excellent effects of proofing corrosion and pests.
Description
Technical field
The present invention relates to a kind of wood preservation method.
Background technology
Timber is one of important source material of nation-building and people's daily living article, such as being used for construction material, industrial materials etc.Along with the raising of people's living standard, to the also day by day increase of demand of timber.Timber is a kind of natural organic, has obvious biological nature, is easily given birth to the biological attack such as boring worm by bacterium, worm, sea.So the long-term use of timber particularly long-term outdoor use is very restricted.Corrupt biology can cause rotting of timber, and it is damaged.Before use, according to different applied environments, select suitable anticorrisive agent, carry out appropriate processing, then can effectively delay foxiness.It is very limited that China can fell the forest reserves of use, and it is unpractical placing hope on and using a large amount of foreign exchange imported timbers.Timber is carried out preservative treatment, one of important channel that be to save timber the service life of prolongation woodwork, protect forest resources.The timber preservative of at present countries in the world use mainly is the CCA anticorrisive agent, and such anticorrisive agent has toxicity owing to materials such as containing arsenic, chromium, is unfavorable for environmental protection, strictly limits use in some countries.
Summary of the invention
The purpose of this invention is to provide a kind of wood preservation method.
Timber preservative of the present invention is comprised of the component of following percentage by weight:
Wherein cupric oxide has preferably inhibitory action to fungi, and moderate cost is environmentally friendly, and harmless to people, animal.Propiconazole has mildew-proof function.Ammoniacal liquor can increase the dissolubility of cupric oxide.Didecyl Dimethy ammonium chloride has bactericidal effect, also can improve the stability of preparation, prevents the precipitation of propiconazole.Eight boric acid disodiums are good anticorrisive agents, good penetrability and have the insect protected function.Timber preservative of the present invention can not use safety to environment, and has significantly anticorrosion and vermins-proof effect.
The preparation method of foregoing preservatives may further comprise the steps:
(1) 4-16% didecyl Dimethy ammonium chloride, 3.6-5.8% eight boric acid disodiums, 1-3% propiconazole and appropriate amount of deionized water are mixed, this mixture is heated to 100-110 ℃, constantly stir until solid dissolves fully;
(2) be cooled to and add 20-30% cupric oxide and 1-3% ammoniacal liquor after the room temperature, adding at last deionized water, to make total weight percent be 100%;
(3) stir until all components dissolves fully.
Wood preservation method of the present invention may further comprise the steps:
(1) timber is placed airtight pressure immersion can, adds the timber preservative that formed by following percentage by weight component to canful:
(2) be forced into 0.8Mpa ± 0.05Mpa, kept about 1-10 hour.
(3) pressure release empty anticorrisive agent side by side.
(4) from tank, take out timber.
