Abstract

The invention discloses a weather-resistant easy-to-clean anti-crack thermal insulation coating based on a concrete surface. The coating comprises a concrete layer, and the concrete layer is sequentially provided with an epoxy primer, a single-liquid anti-vertical-flow non-expansion waterproof thermal insulation type polyurethane material, aromatic polyurethane varnish, polyurethane urea and water-based aliphatic acrylic polyurethane finish paint from bottom to top; the epoxy primer is prepared from epoxy resin, an amino curing agent and a solvent in a mass ratio of 25: 5: 70; the aromatic polyurethane varnish comprises resin and a solvent in a mass ratio of 3: 7; the mass ratio of the resin to the curing agent in the polyurethane urea is 1.05: 1; the mass ratio of the resin emulsion to the curing agent in the water-based aliphatic acrylic polyurethane finishing paint is 9: 1. The coating disclosed by the invention has extremely strong seepage force, can be used on a complete and dry pool wall, and can permeate into a gap of a cement pool to form a continuous and uninterrupted protective film.

Description

technical field [0001] The invention relates to the technical field of coating production, in particular to a weather-resistant, easy-to-clean, anti-crack, heat-retaining coating based on concrete surfaces. Background technique [0002] Concrete has played an irreplaceable role in the aquaculture industry due to its convenient materials, low price, and good compressive performance. However, due to the relatively low tensile strength of concrete, cracks are inevitable in practical engineering applications. The effects of cracks in the concrete structure include the decline in mechanical properties and the decrease in the ability to resist external ion penetration. It is easier to provide a breeding ground for bacteria and viruses, and it is difficult to kill them. Conventional repair methods for concrete cracks mainly focus on after-the-fact repairs: a series of remedial measures are taken to repair the cracks after the cracks are observed artificially. Because these after...
