Problems solved by technology

However, due to many reasons, the preparation technology of this type of antistatic floor paint is not yet fully mature, and most of them are solvent-based floor paints, and these conductive materials will have poor dispersibility and difficult processing when applied to water-based floor paint systems. However, in order to ensure the antistatic performance, it is often necessary to increase the amount of conductive materials added to the coating. On the one hand, the high-filling powder conductive filler will cause some properties of the originally stable coating system to be directly affected after adding conductive materials. , such as water resistance, mechanical strength, weather resistance, anti-aging performance, etc.; on the other hand, the density of the formed coating system will increase greatly, and interlayer peeling and cracking will easily occur after a period of use, directly affecting To the service life of floor paint

Abstract

The invention discloses a water-based epoxy floor paint and a preparation method thereof. The water-based epoxy floor paint uses epoxy resin, filler, deionized water, antistatic agent, dispersant and other auxiliary agents as raw materials to prepare the primer respectively. Paint; use polyurethane resin, titanium dioxide, propylene glycol, color paste, deionized water, dispersant and other additives as raw materials to prepare topcoat, and cooperate with different conductive fillers to form a cross-linked conductive system inside the resin, and improve its internal The stability within the structural system can not only reduce costs and save resources, but also take into account physical strength, chemical corrosion resistance and static conductivity. The prepared water-based epoxy floor paint has controllable cost, good construction performance, smooth surface after drying, excellent water resistance and corrosion resistance performance, and good antistatic effect.

Description

technical field [0001] The invention relates to water-based floor paint technology in the field of organic polymers, in particular to a water-based epoxy floor paint and a preparation method thereof. Background technique [0002] In the prior art, as a new type of coating, epoxy floor paint has the characteristics of strong adhesion, friction resistance, and strong hardness. At the same time, this kind of floor paint mostly adopts a one-time coating process. No connection seams will be produced directly, so it is beautiful and generous, and is accepted and used by many domestic manufacturers and users. Water-based epoxy floor paint is produced using water as a dispersion medium with unique water-soluble materials. Compared with solvent-based epoxy floor paint, a certain amount of volatile organic compounds (VOC) will be emitted during production, construction and curing. It is more in line with the current environmental protection concept; at the same time, water-based epox...
