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 high-efficiency antibacterial antiseptic and a preparation method thereof. In the scheme, the natural antibacterial agent is prepared from Sophora flavescens, Coptis chinensis, Fructus Cnidii and Camphor leaves. Sophora flavescens has good heat-clearing, damp-drying and insecticidal effects Fructus Cnidii is the ellipse dry shape fruit of a kind of Umbelliferae plant Cnidium, and the osthole contained in it has anti-inflammatory, antibacterial, insecticidal effects, and also has obvious inhibitory effect on plant pathogenic fungi; The antibacterial, antiviral, and antiprotozoal pharmacological effects of microorganisms also have a more significant inhibitory effect on fungi; camphor leaves have better anthelmintic effects. , effectively improve the antiseptic performance of the preservative, and also improve the insect repelling and pest prevention performance; the process design of the present invention is reasonable, the operation is simple, and the original used natural herbal medicines and plant extracts are low in cost.

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...
