Embodiment 1

[0038] Example 1: 70% refined petroleum water emulsion (LAO-70). The ingredient formula (mass percentage) is as follows: 68% of 36# hydraulic oil, 4.4% of polyvinyl alcohol, 2.0% of sodium dodecylbenzenesulfonate, 1.2% of alkylphenol polyoxyethylene (10) ether, octylphenol polyoxyethylene Ethylene (4) ether 1.5%, lecithin 1%, fatty alcohol polyoxyethylene (3) ether 2.1%, fatty alcohol polyoxyethylene ether sodium sulfate 0.5%, ethylenediaminetetraacetic acid 0.2%, 2,4-hexadienoic acid Potassium 0.1%, glycerol 0.3%, 500 mesh bentonite 1%, deionized water added to 100%. According to the technological process, it is made by mixing and stirring evenly.

Embodiment 2

[0039]Embodiment 2: 50% refined petroleum water emulsion (LAW-50) ingredient formula (mass percentage) is as follows: 46# white oil 50%, high-fat film 30%, alkylphenol polyoxyethylene (10) ether phosphate 8% , seaweed extract 2%, coconut oil diethanolamide 0.6%, fatty alcohol polyoxyethylene ether 2%, polyvinylpyrrolidone 1.6%, isopropanol 0.3%, and deionized water to 100%. According to the technological process, it is made by mixing and stirring evenly.

Embodiment 3

[0040] Embodiment 3: 40% refining petroleum water emulsion (LAT-40) composition formula (mass percentage) is as follows: 30# machine oil 40%, high-fat film 18%, polyvinyl alcohol 3%, alkylbenzene sulfonate calcium (agricultural milk 500) 8%, alkylphenol polyoxyethylene ether 2%, sorbitan oleate polyoxyethylene ether (Tween 65) 3.5%, fatty acid polyoxyethylene ether 2%, octachlorodipropyl ether 1.8%, Compound sodium nitrophenolate 1.2%, aluminum magnesium phosphate 0.8%, ethylene glycol 0.4%, glycerol 0.2%, deionized water added to 100%. According to the technological process, it is made by mixing and stirring evenly.

[0041] How to use: To control aphids, mites, scales, leafhoppers, black thorn whitefly, etc., use this agent to add 300-800 times of water and spray. To clear the garden in winter and spring, to remove lichen, moss, scale shell, soot, etc., use this agent to add 200-500 times of water and spray. To control tea inchworms, caterpillars, tea silkworms, etc., use ...

Abstract

The invention relates to a production process of refined petroleum emulsion in water and belongs to the field of pesticide manufacturing process. The refined petroleum emulsion in water is made from refined petroleum, film-forming agent, emulsifiers, plant nutrients, defoaming agent, stabilizers, antifreezing agent and deionized water, by uniform dispersion using a high-speed shear mixing emulsifier. The refined petroleum emulsion is innoxious and non-irritant or low-toxic or low-irritant to animals and human beings, is harmless to crops, has environmental affinity, enhances the resistance of crops, and can promote the growth of crops. The refined petroleum emulsion can kill main insect pests, regulate the growth of crops, enhance resistance to cold and diseases and increase the yield of crops. The invention has the advantages of use of water as solvent, reduced waste of resources, no discharge of three wastes, environmental friendliness, scientific formulation, advanced process, low cost and good effect.

Description

technical field [0001] The invention relates to a petroleum water emulsion. It belongs to the manufacturing process and method of pesticide. Background technique [0002] Since the 1970s, new formulations of pesticides have flourished. The Pesticide Formulation Catalog and International Code System published by the International Pesticide Industry Association (GIFAP) for the first time in 1978 lists 51 formulations. In 1984, 64 dosage forms were listed. After revision in 1989, 71 dosage forms were listed. With the development of pesticide dosage form processing, there is a trend of diversification of dosage forms and preparations. In particular, pesticide dosage forms that are highly efficient, safe and low-pollution, and compatible with users and the environment are valued. Liquid preparations that use water as the base without or with less organic solvents Suspension concentrates, emulsions in water, and water formulations will develop rapidly, while sales of emulsifia...
