Problems solved by technology

[0004] In the preparation process of epoxy emulsifiers, it is often necessary to use a large number of long hydrophilic chains to ensure the emulsification effect. These long hydrophilic chains have fewer bonding points with the coated substrate, resulting in the wetness of the coating on the surface of the substrate. Poor adhesion, which affects the resistance and protective properties of the coating

Abstract

The invention belongs to the field of epoxy emulsifiers, and discloses a phosphate-type waterborne epoxy emulsifier as well as preparation and application thereof. The structure of the emulsifier disclosed by the invention contains an epoxy group which can participate in a curing reaction in a film-forming process so as to be anchored in a coating and is not easy to migrate; a nonionic polyether long chain can migrate to the surfaces of latex particles in an emulsion process to form a hydration shell so as to stabilize the latex particles, and can provide certain viscosity and thixotropy for a waterborne epoxy emulsion simultaneously to effectively control the rheological property of an emulsified waterborne epoxy emulsion; the structure of the emulsifier contains a basic epoxy structure which can improve the compatibility of the emulsifier and epoxy resin; a tertiary amine group in the structure provides a basic group which can form a zwitterionic structure with a phosphate group, thus enabling the emulsifier to have good emulsifying capacity within a relatively wide pH (Potential of hydrogen) range, and the introduction of the phosphate group can improve the adhesive force of waterborne epoxy paint on the surface of a substrate and the coating tolerance after curing.

Description

technical field [0001] The invention belongs to the field of epoxy emulsifiers, in particular to a preparation method and application of a water-based epoxy emulsifier. Background technique [0002] With the improvement of environmental protection awareness, the demand for water-based epoxy coatings is increasing, starting from water-based epoxy floors and gradually expanding to large-scale steel structures and containers, that is, from the field of light anti-corrosion to the field of heavy anti-corrosion. [0003] Basic epoxy is a viscous liquid or solid at room temperature. It is a thermoplastic linear structure and has low solubility in water. Therefore, converting solvent-based epoxy into water-based epoxy resin is an important step in the preparation of water-based epoxy resin. The widely used method is: using an emulsifier to emulsify and disperse basic epoxy in water to prepare water-based epoxy resin. Emulsifiers include non-reactive emulsifiers and reactive emuls...
