Problems solved by technology

However, wood products are easily infected with fungi during use. If they are not treated with anti-corrosion, the service life of wood products will be greatly reduced. Therefore, in order to prolong the service life of wood products and protect forest resources on the earth, wood product preservatives have been obtained. great development
However, the common preservatives currently used are very toxic to humans, and after these preservatives treat wood products, it will make wood products difficult to degrade, which has caused great damage to the environment on the earth.

Abstract

The invention discloses a plant extract preservative which is prepared from the following components in parts by weight: 25-30 parts of sassafras extract, 20-30 parts of schima superb extract, 15-20 parts of elaeocarpus hainanensis extract, 6-8 parts of sodium alginate, 3-5 parts of calcium chloride, 4-6 parts of magnesium sulfate, 2-5 parts of ferric nitrate and 30-35 parts of ethyl ether. The preservative provided by the invention can restrain increase of mildew and insects for a long time, is remarkable in pesticide effect and is long in residual period. Moreover, the preservative provided by the invention is green, is environmentally friendly, is relatively low in toxicity, does not cause any harm on environment after being used, and is easy to degrade.

Description

technical field [0001] The invention relates to the field of wood product antisepsis, and specifically designs a plant extract antiseptic. Background technique [0002] At present, wood products have entered thousands of households, and wood products with great ornamental and practical value are deeply loved by consumers. However, wood products are very easy to be infected with fungi during use. If they are not treated with antiseptic treatment, the service life of wood products will be greatly reduced. Therefore, in order to prolong the service life of wood products and protect forest resources on the earth, wood product preservatives have been obtained developed greatly. However, the common preservatives currently used are very toxic to humans, and after these preservatives have treated wood products, it will make the wood products difficult to degrade, which has caused great damage to the environment on the earth. Therefore, there is an urgent need for an environmentall...
