Antiseptic wood for municipal gardens

Abstract

The invention discloses antiseptic wood for municipal gardens. The antiseptic wood is prepared in the following steps of air-drying wood in air until the moisture content is less than 15%, so that air-dried wood is obtained; soaking the air-dried wood in antiseptic treatment liquid in wood antiseptic vacuum pressurizing equipment, soaking for 1 h to 26 h at the vacuum degree of minus 0.1 MPa to minus 0.08 MPa, and then keeping the pressure of the vacuum soaked wood for 1 h to 48 h under the pressure of 0.2 MPa to 5 MPa, so that the wood after vacuum pressurizing soaking treatment is obtained; and air-drying the wood after the vacuum pressure soaking treatment in the air, so that air-dried soaked wood is obtained, and then heating and dying the air-dried soaked wood by utilizing an air dry oven, so that the antiseptic wood is obtained. The antiseptic treatment liquid is prepared from effective components including Taxol C and coetsoidin A.

Description

technical field [0001] The invention relates to a preservative wood for municipal gardens. Background technique [0002] Wood is a kind of biomass porous material, which is easily decayed by microorganisms and insects. In particular, wooden products are used outdoors, which has higher requirements for wood preservative properties. Preserving wood through physical or chemical methods is an effective way to improve wood preservative properties. Wood preservatives mainly include oil preservatives (such as creosote and scallion oil), oil-borne preservatives (such as pentachloro phenols, naphthenic acid ketones, etc.) and waterborne preservatives (chromium arsenic acid ketones, inorganic metals and inorganic Pengs). Water-borne preservatives are the most widely used at present, but the technical problems are that the anti-loss of preservatives is poor and the distribution of preservatives in wood is uneven. Creosote is a traditional oil preservative, but in addition to its tox...

However, the arsenic and chromium contained in CCA have potential hazards to human beings and applied environmental soil and water sources. There is still no proper way to dispose or recycle CCA treated materials. Therefore, many European and American countries, such as the United States, Canada, and Germany, have begun to ban CCA.
