Abstract

The invention belongs to the technical field of preservatives, and particularly relates to a wood preservative. According to the wood preservative, first of all, sodium periodate is added and stirred after corn starch and water are mixed; after the PH value is adjusted, reaction is conducted through heat preservation and stirring, and then a reactant is mixed with acetone and filtered, modified starch is obtained after filter residue is dried; then cocamidopropyl dimethylamine oxide, triadimenol, isopropanol and the like are stirred and then mixed with deionized water to form oil-in-water type emulsion; after being dissolved by the deionized water, the modified starch is mixed with wood vinegar, natamycin and the like to obtain a biological antibacterial agent solution; and finally the biological antibacterial agent solution and the oil-in-water type emulsion are blended and injected packaged at equal proportions, and thus the wood preservative can be obtained. The prepared wood preservative has good effects of being mildew-proofing, insect-proofing and corrosion-proofing, and meanwhile is green and environmentally friendly, cannot make any damage on the environment and human bodies after being used, and is good in corrosion-proofing effect and long in prevention effect and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of preservatives, and in particular relates to a wood preservative. Background technique [0002] Wood is the only renewable structural material among the four major materials. It has the characteristics of non-toxic, non-polluting, beautiful, and easy to process. It is the most friendly to human beings and is a green natural product that is loved by people. However, the main components of wood are lignin, cellulose, and hemicellulose. When the temperature, moisture, humidity, and pH are suitable, they are easily corroded by insects and fungi, which shortens the service life of wood. According to statistics, the service life of wood after anti-corrosion treatment can be extended by 5 to 6 times. Therefore, antiseptic treatment of wood is an important way and means to prolong the service life of wood, improve the level of wood utilization and save wood resources. [0003] There are many types of wood preser...
