Solvent-free epoxy self-leveling roller coating floor paint and preparation and use method thereof

Abstract

The invention relates to a solvent-free epoxy self-leveling roller coating floor paint and a preparation and use method thereof. The paint comprises a low-viscosity epoxy resin compound, an active diluent, an inactive diluent, a defoamer, a leveling agent, a wetting dispersant, a thixotropic additive, a solvent-free phthalocyanine blue pulp, a solvent-free lemon yellow pulp, a solvent-free titanium white pulp, a solvent-free carbon black pulp, quartz powder, precipitated barium sulfate and a modified alicyclic amine curing agent. The preparation and use method comprises the following steps: preparation of various solvent-free individual color pulps, preparation of a component A and use manner; the low-viscosity epoxy resin compound is a compound of bisphenol-A epoxy resin and bisphenol-F epoxy resin, the viscosity of the compounding system is greatly reduced under the condition of no solvents, the viscosity of the solvent-free system is improved, the amount of the active diluents and the inactive diluents is reduced, the physical mechanical performances of coatings are guaranteed and the paint is endowed with excellent levelability, so that the paint disclosed by the invention has roller coating self levelability and excellent construction performance.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly floor coatings, and in particular relates to a solvent-free epoxy self-leveling roller-coated floor coating and a preparation method thereof. Background technique [0002] Floor coatings only began to be gradually popularized and applied in the 1990s, but the floor coating industry has developed rapidly. At present, basically all modern factories have begun to use floor coatings. In 2011, the output value of floor coatings has exceeded 18 billion yuan. With the rapid development of modern industrial technology and production, owners have put forward higher and higher requirements for the production environment of factories and workshops, requiring floor coatings to be corrosion-resistant, clean and wear-resistant, with low dust content in indoor air and high construction efficiency. This is not only a demand for improving working conditions, but also a guarantee for the quality of mod...

Problems solved by technology

[0006] Chinese patent CN103525249A discloses a solvent-free epoxy self-leveling floor coating and its preparation method and application method. This solvent-free epoxy self-leveling floor coating topcoat is applied by trowel coating, and the film thickness reaches 2-3mm. The amount used has reached 3.2~4.8kg / m 2 , not only the amount of construction materials is wasted, but also the thickness of a film is large, and the great cohesion of the paint film may damage the concrete structure of the base and cause floor damage.

[0007] In summary, there are no relevant reports on solvent-free floor coatings with convenient construction, wide application range and low cost.
