Inorganic flake water-based epoxy resin coating

Abstract

The invention discloses an inorganic flake water-based epoxy resin coating, which is composed of a component A and a component B, wherein the component A is an epoxy resin dispersion and comprises the following components by weight percent: 60-80% of bisphenol low-molecular-weight liquid epoxy resin, 5-10% of active thinner, 0.2-1.0% of dispersing agent A, 0.05-0.1% of deforming agent A, 0.2-0.8% of non-ionic surface active agent, 0.1-0.2% of anti-settling agent, 8-40% of physical filler, and 5-20% of inorganic flake material; and the component B is a hydrophilic water-based curing agent dispersion and comprises the following components by weight percent: 43-65% of modified water-based amine curing agent, 35-50% of water, 0.2-0.4% of dispersing agent B, 0.2-0.5% of deforming agent B, and 0.2-0.8% of flatting agent. The inorganic flake water-based epoxy resin coating disclosed by the invention has good water-resistance performance and is applied to buildings, therefore, the surface of a concrete or mortar substrate layer can be closed after being coated; various penetrated water vapour is thoroughly isolated; and surface decorative layers of building envelopes, such as coatings, wallpapers, wood floors and the like, are prevented from being affected with damp.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an inorganic flake water-based epoxy resin coating. Background technique [0002] The floor in the building envelope is generally made of Portland concrete or cement mortar. Silicate materials will produce a large number of micropores during the solidification process, which has hydrophilic properties and can easily absorb water and water vapor. The building decoration floor is laid with decorative wooden panels. Due to temperature changes and other reasons, water vapor molecules escape from the micropores on the surface of the building floor, and some of them condense into water, causing the wooden floor to be damp. After being damp, the wooden floor is prone to deformation, arching, tiles It is also easy to breed termites and be eroded by termites, which greatly shortens its service life. [0003] The walls of building envelopes in interior decoration and renovation projects...

AI Technical Summary

Problems solved by technology

Once the wall is damp, the decorative paint or wallpaper on the wall is prone to delamination, peeling and mildew; and the wooden materials used, such as door frames, fixed furniture, etc., will also be deformed and breed termites after the wall is damp etc., thus affecting its service life

[0004] In order to achieve a waterproof effect, the building maintenance structure adopts traditional polymer cement-based waterproof coatings such as JS waterproof coating film or K11 waterproof coating film, but these coatings cannot achieve a good moisture-proof effect, because polymer cement-based waterproof coatings belong to Hydrophilic building materials will also form continuous pores during the film forming process, and the pore size distribution is generally between 5-15nm. Therefore, although it has a certain waterproof effect, it can also pass through water vapor molecules and does not have the effect of moisture resistance.
