Problems solved by technology

[0004]With the development and improvement of social economy, my country's demand for wood is increasing day by day. At the same time, in line with the idea of ​​protecting the environment, we have The requirements are getting higher and higher. It is hoped that the existing wood preservatives can effectively prevent wood from pests and increase the service life of wood. However, due to factors such as rainwater and humid environments in actual use, the service life of preservatives will be greatly affected, which brings inconvenience to our research

Abstract

The invention discloses a natural efficient antibacterial preservative and a preparation method thereof. According to the scheme, a natural bacteriostatic agent is prepared from radix sophorae flavescentis, coptis chinensis, fructus cnidii and cinnamomum camphora leaves, the radix sophorae flavescentis has good effects of clearing heat, drying dampness and killing insects; fructus cnidii is an oval dry fruit of umbelliferae plant cnidium monnieri, and the contained cnidium lactone has the effects of diminishing inflammation, resisting bacteria and killing insects, and also has an obvious inhibiting effect on plant pathogenic fungi; coptis chinensis has the antibacterial, antiviral and anti-protozoon pharmacological effects against pathogenic microorganisms, and also has a remarkable inhibition effect on fungi; and the cinnamomum camphora leaves have a good insect expelling effect. According to the invention, the radix sophorae flavescentis, coptis chinensis, fructus cnidii and cinnamomum camphora leaves are coordinated with each other, thus effectively improving the corrosion resistance of the preservative, and also improving the insect expelling and insect pest preventing performance at the same time. The process adopted by the invention is reasonable in design and easy to operate, the used raw materials are natural herbal medicines and plant extracted liquid, and the cost islow.

Description

technical field [0001] The invention relates to the technical field of preservatives, in particular to a natural high-efficiency antibacterial antiseptic and a preparation method thereof. Background technique [0002] Wood Preservative (Wood Preservative) is a kind of chemical agent, after it is injected into wood in a certain way, it can enhance the wood's resistance to fungal decay, insect damage, marine borer erosion, etc.; before use, according to different In the application environment, choosing a suitable preservative can effectively delay the decay of wood after treatment. [0003] Wood preservatives include the following: water-borne (water-soluble) preservatives, such as CCA, ACQ, CA-B, CB-A, ACZA, ACC, CC, etc.; organic solvent preservatives, such as pentachlorophenol, chlorothalon Qing, copper naphthenate, etc., copper 8-hydroxyquinolinate; oil preservatives, such as anti-corrosion oil, coal tar, anthracene oil, etc. [0004] With the development and improvemen...
