Abstract

The invention discloses an antistatic waterborne epoxy floor coating top finish and a preparation method thereof. The antistatic waterborne epoxy floor coating top finish is prepared from A and B components, wherein the A component is prepared from a waterborne epoxy resin curing agent II, water, a volume filler, an antistatic material, a promoter and a color paste; the B component is prepared from bisphenol A type epoxy resin and an active diluent. The preparation method comprises the following steps: dissolving the waterborne epoxy resin curing agent and a part of promoter in a part of water, adding the volume filler, grinding, then adding the antistatic material and the residual water, stirring, uniformly dispersing, sieving, matching color by virtue of the color paste, and then adding the residual promoter to prepare the A component; and preparing the B component into the A component according to the mass ratio to obtain the antistatic waterborne epoxy floor coating top finish. The antistatic waterborne epoxy floor coating top finish is safe, environmentally friendly, low in cost and good in antistatic function. The preparation method is simple, is low in the cost and can be used for industrial production.

Description

technical field [0001] The invention relates to a water-based epoxy antistatic floor coating topcoat and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] The rapid development of modern science and technology and production puts forward higher and higher requirements for the floors of factories, workshops, laboratories and so on: first, high cleanliness. The floor of the workshop is required to be corrosion-resistant, clean and wear-resistant, and the dust content of the indoor air should be as low as possible. This is not only a requirement for improving working conditions, but also a guarantee for product quality; second, to eliminate static electricity accumulation. Due to frequent friction, the floor tends to accumulate a large amount of static electricity, which hinders production operations, interferes with the work of precision instruments, affects product processing accuracy, and even causes fires, explosions a...
