Low-toxicity wood mould inhibitor and preparing method thereof

Abstract

The invention discloses a low-toxicity wood mould inhibitor. The low-toxicity wood mould inhibitor comprises the following raw materials including, by weight, 3-6 parts of atractylodes lancea, 2-4 parts of mugwort leaves, 3-6 parts of pyrethrums, 4-6 parts of sophora flavescens, 3-7 parts of radix stemonae, 5-7 parts of cloves, 0.01-0.05 part of dichloroethenyl salicylamide and 3-5 parts of sodium chloride. By means of the wood mould inhibitor, the traditional Chinese medicines including the atractylodes lancea, the mugwort leaves, the pyrethrums, the sophora flavescens, the radix stemonae and the cloves are added, a good mould preventing effect is achieved, the cost of raw materials is low and is one third of that of a chemical treating agent, little pollution is generated in the preparing and using processes, and the wood mould inhibitor is safe and environment-friendly compared with a traditional wood mould inhibitor; in addition, the sodium chloride is added, and the functions of color fixing and sterilizing are achieved; and due to the fact that the dichloroethenyl salicylamide is added, the mould preventing effect is further improved, and the service life of a wood product is greatly prolonged. Meanwhile, the invention provides a preparing method of the low-toxicity wood mould inhibitor, the technology is simple, operation is convenient, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of antifungal agents, in particular to a low-toxic wood antifungal agent and a preparation method thereof. Background technique [0002] Wood is a natural polymer material with obvious biological characteristics. It is prone to mildew during use and affects the service life of wood products. Therefore, it is necessary to carry out anti-mildew treatment on the wood before use. The current treatment agents mostly use pure chemical agents, such as water-soluble alkyl ammonium compounds (AAC), ammonia-soluble quaternary ammonium copper (ACQ), borides, bis-dimethyl Copper dithiocarbamate (CDDC) and oil-soluble copper / zinc naphthenate, chlorothalonil (CTL), organic iodide (IPBC), etc., the production cost is too high, and although the chemical raw material antifungal agent is harmful to microorganisms It has a certain inhibitory effect, but it is highly toxic and pollutes the environment. During the use of the pr...
