Abstract

The invention belongs to the technical field of surfactants and particularly relates to a compound nonionic surfactant which is prepared by compounding the following components in parts by weight: 20-80% of a component A and 20-80% of a component B, wherein the component A is formed by the combination of one or more of cardanol polyoxy alkyl ether, and the component B is formed by the combination of one or more of fatty alcohol polyoxy alkyl ether. The compound nonionic surfactant gives full play to the advantages of good low-temperature fluidity, strong emulsifying capacity and good decontamination and oil removing effects of the cardanol polyoxy alkyl ether, so that the compound nonionic surfactant can be applied to multiple fields including spinning, daily chemical, pesticides, metal processing and the like to replace conventional APEO.

Description

technical field [0001] The invention belongs to the technical field of surfactants, in particular to a composite nonionic surfactant. Background technique [0002] Surfactants are widely used and have penetrated into various civil and industrial fields. Among them, nonionic surfactants do not ionize in water, and are amphiphilic molecules with hydroxyl or ether bonds as hydrophilic groups. Due to the nonionic surface Active agents have the characteristics of non-ionization in water, which makes non-ionic surfactants superior to ionic surfactants in some aspects, such as better solubility in water and organic solvents, and high stability in solutions , not easily affected by strong electrolyte inorganic salts and acids and bonds. Because of its good compatibility with other types of surfactants, it can often be mixed and compounded well. Nonionic surfactants have good hard water resistance and low foaming properties, so they are suitable for special detergents. Because of ...
