Abstract

The invention discloses aqueous antistatic epoxy floor paint and a preparation method and application thereof. The preparation method comprises the following steps of: mixing 40 to 45 parts of epoxy resin, 1 to 4 parts of active thinner, 12 to 18 parts of color paste, 0.05 to 0.2 part of dispersant, 0.05 to 0.2 part of wetting agent, 0.1 to 0.5 part of flatting agent, 0.1 to 0.5 part of antifoaming agent, 0.01 to 0.1 part of defoamer, 0.5 to 2 parts of organic wax powder, 2 to 6 parts of quartz powder, 20 to 30 parts of calcium carbonate and 5 to 10 parts of conductive fiber to obtain a component A; mixing 50 to 80 parts of aqueous curing agent, 0.5 to 2 parts of aqueous film-forming aid, 20 to 50 parts of water and 0.05 to 0.2 part of flatting agent uniformly to obtain a component B; mixing the component A and the component B uniformly in a substance mole ratio of active hydrogen content in the aqueous curing agent to epoxy group content in the epoxy resin of 1: 1 to obtain the aqueous antistatic epoxy floor paint with low resistance, high hardness and abrasion resistance.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a water-based antistatic epoxy floor coating and a preparation method and application thereof. Background technique [0002] As a functional coating, anti-static floor coatings have been widely used in the field of architectural coatings with anti-static requirements. [0003] Traditional antistatic floor coatings are mostly prepared by mixing liquid epoxy resin with conductive fillers, but most of them have high surface resistivity (10 7 ~10 9 Ω), in addition, in order to achieve the purpose of conducting through the insulating coating, most of them choose to add conductive fibers as conductive fillers, and the dispersion and uniform and effective distribution of conductive fibers (such as figure 1 shown) has become a major problem for manufacturers and construction companies. figure 1 In the coating, the conductive fibers are distributed in a floating state, which canno...

Problems solved by technology

[0003] Traditional antistatic floor coatings are mostly prepared by mixing liquid epoxy resin with conductive fillers, but most of them have high surface resistivity (10 7 ~10 9 Ω), in addition, in order to achieve the purpose of conducting through the insulating coating, most of them choose to add conductive fibers as conductive fillers, and the dispersion and uniform and effective distribution of conductive fibers (such as figure 1 shown) has become a major problem for manufacturers and construction companies. figure 1 In the coating, the conductive fibers are distributed in a floating state, which cannot form an effective conductive channel between the surface and the bottom of the paint

In addition, some manufacturers use solvent-based epoxy resins to prepare antistatic floor coatings, although the surface resistance of such floor coatings is low (10 5 ~10 7 Ω), but there are defects such as insufficient hardness of the coating film and poor wear resistance, and it is not environmentally friendly, so it has been phased out of the market
