Problems solved by technology

[0003] At present, there are mainly two kinds of compound products that carvacrol is used in fungicides: one is 5% fungal water purifier (produced by a pesticide factory), which is composed of 2.5% carvacrol and 2.5% acrylic acid It is compounded. Because it is a water agent, its stability is poor, and oily substances are easily precipitated on the surface, which reduces the use effect. Acrylic acid is a kind of industrial raw material, which has strong corrosion and irritation, causing certain pollution, and the cost of acrylic acid Higher (about 3 times that of wood vinegar), which increases the application cost
Another compound is 2.1% eucarvacrol aqueous solution (produced by a certain biochemical Co., Ltd.), which is a compound of 0.3% eucarvacrol and 1.8% carvacrol. Although it has a wide bactericidal spectrum, it produces The cost is high, and because it is a water agent, its stability is poor, and the use effect is not stable

Abstract

The invention relates to a carvacrol microemulsion and a production process thereof, and relates to the technical field of carvacrol microemulsion pesticide. The carvacrol microemulsion comprises the following compositions in portion by weight: 2.0 to 6.0 portions of carvacrol, 43 to 70 portions of pyroligneous liquid (or water), 8.0 to 20 portions of emulsifier and 20 to 31 portions of solvent, and is prepared by mixing, stirring and emulsifying. The carvacrol microemulsion has the advantages that the carvacrol microemulsion has strong stability, good sterilizing effect, good control efficiency, environmental protection and safety, wide range of application, low cost, and high economic benefit and social benefit, and can increase the prophylactic variety; and the production process is simple, unique and pollution-free, and has low cost.

Description

technical field [0001] The invention relates to the technical field of carvacrol microemulsion pesticides. Background technique [0002] Carvacrol is the main component of oregano oil, which is an extract of oregano grass, which can also be artificially synthesized. Carvacrol is insoluble in water, but soluble in organic solvents such as ether and ethanol. Carvacrol has a special aroma and strong antibacterial properties, and is widely used in industries such as spices, food and feed additives, and fungicides. [0003] At present, there are mainly two kinds of compound products that carvacrol is used in fungicides: one is 5% fungal water purifier (produced by a pesticide factory), which is composed of 2.5% carvacrol and 2.5% acrylic acid It is compounded, because it is a water agent, its stability is poor, and oily substances are easily precipitated on the surface, which reduces the use effect. Acrylic acid is a kind of industrial raw material, which has strong corrosion an...
