Description

technical field [0001] The invention relates to the technical field of epoxy floors, in particular to a water-based antistatic epoxy floor paint and a preparation method thereof. Background technique [0002] The bisphenol A type epoxy resin of the present invention is a thermosetting resin with excellent anticorrosion performance and environmental friendliness, therefore, it is widely used in epoxy floor paints and in organic anticorrosion coatings. Traditional epoxy floor paint consists of two components, A and B. Usually, the curing agent is a separate component, which is mixed with bisphenol A epoxy resin to cure before use. The water solubility of materials within two components, and the compatibility between the two components have been the focus of research. Especially the water solubility of bisphenol A epoxy resin and the compatibility with curing agent. Therefore, preparing a curing agent with bisphenol A type epoxy resin emulsifying function is one of the ways t...
