Abstract

The invention discloses a cardanol ester-based agricultural high molecular emulsifying agent and a preparation method and a using method thereof, and belongs to the field of high molecular materials.The cardanol ester-based agricultural high molecular emulsifying agent comprises the following components in parts by weight: 1-70 parts of high molecular polymeric acid, 30-50 parts of cardanol, 0.01-10 parts of a catalyst and 1-40 parts of triethanolamine. The high molecular emulsifying agent prepared by the preparation method provided by the invention can better wrap an oil phase because of relatively large molecular weight and existence of a long hydrophobic chain; compared with the conventional small molecular emulsifying agent, the emulsion provided by the invention has the advantages ofstronger stability and excellent performance; in addition, a preparation technology is simple and environment-friendly.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a cardanol ester agricultural polymer emulsifier and a preparation and use method thereof. Background technique [0002] An emulsifier is a substance used to prepare an emulsion and give it a minimum degree of stability, and is an essential component. Common emulsifiers are small molecule emulsifiers, mainly nonionic emulsifiers such as alkylphenol polyoxyethylene ether and cardanol polyoxyethylene ether, and anionic emulsifiers such as alkylbenzene sulfonate. Polymer emulsifiers generally refer to polymer compounds with a relative molecular mass of several thousand or more and surface-active functions. According to the source, polymer surfactant compounds can be divided into natural polymer surfactants, natural modified (or semi-synthetic) polymer surfactants and chemically synthesized polymer surfactants. Natural polymer surfactants exist in animals and plants and play a very...
