Description
Technical Field
The invention belongs to the field of processing of chemical additives, and particularly relates to a preparation method of a high-molecular emulsifier.
Background
The emulsifier is generally divided into 3 types, namely a traditional micromolecule emulsifier, a reactive emulsifier and a polymer emulsifier. The traditional small molecular emulsifier can be brought into a final product and can be transferred to the surface of a film in the process of emulsion film forming, so that the glossiness and the water resistance of the film are reduced. Although the reactive emulsifier can avoid or overcome the defects of the small molecular emulsifier, the viscosity and the particle size of the emulsion are increased to a certain extent, so that the stability of the system is reduced. The structure of the polymer emulsifier is basically the same as that of the water-based varnish, so that the compatibility of the polymer emulsifier and the water-based varnish is greatly improved, the particle size of the emulsion is reduced, and the film-forming glossiness is increased.
