Abstract

A pesticide emulsifier disclosed in the invention is characterized in comprising the following raw materials by weight: 35-45% calcium dodecyl benzene sulfonate, 10-20% phenylacetaldehyde phenyl ethoxylates, 15-20% alkylphenol formaldehyde polyoxyethylene, 15-20% phenylacetaldehyde phenyl ethoxylates - polyoxypropylene ether, and 10-15% xylene. The pesticide emulsifier has the advantages of good low temperature flowability, good emulsifying performance, low dose, good penetration and diffusion performance and low cost, especially for using in the pesticide preparation.

Description

Technical field: [0001] The invention relates to an emulsifier, in particular to an emulsifier for preparing pesticides. Background technique: [0002] At present, emulsifiers are used in the preparation of pesticides in my country. There are many types of emulsifiers, such as 2201, 0204, 8206 and other emulsifiers. These emulsifiers have the disadvantages of poor low temperature fluidity, poor penetration and diffusion performance, large dosage, and high cost. Invention content: [0003] The object of the present invention is to provide a pesticide emulsifier with good low-temperature fluidity, excellent emulsifying performance, less dosage, good penetration and diffusion performance and low price. [0004] The object of the present invention is achieved like this: a kind of pesticide emulsifier is characterized in that it is made up of following raw material by weight: calcium dodecylbenzene sulfonate 35-45%, styrene phenyl polyoxyethylene ether 10 -20%, Alkylphenol for...
