Problems solved by technology

Generally, the antistatic property of epoxy floor paint is increased by adding conductive fillers, but the compatibility between conductive fillers and polymers is poor, which will reduce the mechanical properties of epoxy floor paint, and the dispersion of conductive fillers is poor, so it cannot be used on epoxy floors. Effective conductive channels are formed on the surface and inside of the flat paint to increase anti-static performance

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...
