Even；Resulting material is levigate, control fineness of the particles≤50 μm；Add antistatic material and excess water, continue dispersed with stirring equal
Even；After crossing 200 eye mesh screens, mill base is added to be mixed colours, the levelling agent being simultaneously introduced in auxiliary agent and defoamer are uniformly dispersed；Bag
Dress, obtains final product component A；Allocate the bisphenol A type epoxy resin of respective quality and reactive diluent into as B component, packed, standby
With.
Beneficial effects of the present invention：The present invention adopts bisphenol A type epoxy resin and II for aqueous epoxy resin curing agent body
It is for film forming matter, using conductive fiber and conductive paste as conductive materials, uses water as solvent, make safety and environmental protection, honest and clean
The good water-base epoxy antistatic floor coatings finish paint of valency, electrostatic-proof function.The water-base epoxy antistatic floor coatings face of the present invention
, with water as solvent, organic volatile is few, abnormal smells from the patient is little, energy-conservation, safety and environmental protection, and construction tool can be cleaned up with water, not only for paint
Reduce use cost, meet environmental regulation again, free from environmental pollution；And the composite anti-static material using conductive fiber and conductive paste
Material, and the finish paint compatibility is good, is uniformly dispersed, conductive fiber is in that interval is distributed, and is used alone the effect not reaching static conductive, and leads
Although plasma-based conductive effect is not so good as conductive fiber, its structure is in continuous distribution with fine particle, can form continuous phase, therefore adopt
Based on conductive paste, it is aided with conductive fiber as main conductive material, both use cooperatively the static conductive way it is ensured that whole coating
Footpath is unobstructed；The preparation method of coating is simple, no equipment requirements, low cost, can be with industrialized production.
