Problems solved by technology

[0003] Aerosols were studied abroad earlier, but their development was slow, and most of them were used in health and epidemic prevention. In the 1970s and 1980s, several varieties of aerosols appeared in forest and rubber pest control.
But do not see the domestic and foreign bibliographical reports about copper rosinate aerosol as yet so far

Embodiment 1

[0026] The composition and content of the formula of copper rosinate aerosol are: 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)- Copper 1-phenanthrene carboxylate is also known as copper rosinate 5%, composite surfactant alkylphenol polyoxyethylene ether 0.1%, solvent aromatics No. Diols total 15% in any proportion.

[0027] The preparation of the aerosol is carried out in a preparation kettle, and the processing procedure is as follows: firstly, the active ingredient 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1 -Methylethyl)-1-phenanthrene carboxylate copper, also known as copper rosinate, is added to the preparation kettle together with solvent and co-solvent, and after stirring and heating below 50°C until completely dissolved, then add the composite surface active Continue to stir and heat until it becomes a uniform transparent solution, filter to remove a small amount of residue, and the filtrate is qualified to obtain the copper rosinate aerosol of t...

Embodiment 2

[0029] The composition and content of the copper rosinate aerosol formulation are: 30% copper rosinate, 5% calcium alkylbenzenesulfonate composite surfactant, 60% o-dichlorobenzene solvent, N,N-dimethylformamide as a cosolvent 5%. Preparation method is the same as embodiment 1

Abstract

The present invention relates to a copper rosinate smoking agent and its preparation method. Its formula is formed from (wt%) 5-40% of copper rosinate, 0.1-15% of compound surfactant, 25-80% of solvent and 1-20% of cosolvent. The solvent is noe of arene No.2 or No.3, chloroben, chlorobenzene, diglycol, triglycol, propanediol, liquid paraffin, white oil, castor oil and pine cone oil or several kinds of them, and the cosolvent is one of methyl-sulfoxide, N,N-dimethylformamide, ethanediol and propanetrial or several kinds of them, and the compound surfactant is one of nonyl phenol polyethenoxyether, calcium dodecylbenzenesulfonate, sorbitan oleate and sec-alkylol polyethenoxy ether or several kinds of them. Besides it also provides preparation method.

Description

technical field [0001] The present invention relates to a broad-spectrum fungicide, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)- Copper 1-phenanthrene carboxylate (also known as copper rosinate) aerosol (or thermal aerosol) and a preparation method thereof. technical background [0002] Copper rosinate is an organic copper fungicide, the main features are: 1. Broad spectrum. Effective against a variety of pests; 2. High efficiency. Among the current low-toxic fungicides, the efficacy of copper rosinate is relatively high. There are manufacturers in China that produce copper rosinate fungicides, and their products are emulsifiable concentrate preparations. The emulsifiable concentrate preparations are mainly prepared by solvents such as toluene and xylene with lower boiling points at home and abroad. In the process of use, it needs to be mixed with a large amount of fresh water to form an emulsion before spraying. This product and method of use are more...
