Abstract

The invention discloses a fair-faced concrete protecting agent and a construction method thereof. The fair-faced concrete protecting agent comprises a sealing prime coat component and a photocatalytic topcoat component. The sealing prime coat component is prepared from the following raw materials in parts by mass: 40 to 60 parts of a fluorocarbon resin emulsion, 2 to 6 parts of a film-forming agent, 2 to 3 parts of a silane coupling agent, 2 to 3 parts of a thickening agent, 0.1 to 0.2 part of a defoaming agent, 1 to 1.5 parts of a dispersing agent, 5 to 10 parts of a cosolvent and 30 to 50 parts of water. The photocatalytic topcoat component is prepared from the following raw materials in parts by mass: 5 to 7 parts of modified graphene loaded titanium dioxide powder, 9 to 12 parts of polydimethylsiloxane and 30 to 50 parts of methylbenzene. The fair-faced concrete protecting agent provided by the invention has good compactness and hydrophobicity, can be prevented from being eroded by acid, alkali, salt, grease and the like, can effectively prevent carbonization, can inhibit growth of microorganisms such as moss, algae, molds and the like on the surface of fair-faced concrete, and also can effectively perform photocatalytic degradation on harmful substances such as formaldehyde.

Description

technical field [0001] The invention belongs to the technical field of clear-water concrete surface treatment, and in particular relates to a clear-water concrete protective agent and a construction method thereof. Background technique [0002] With the rapid development of society, concrete structures play an increasingly important role in urban construction. Fair-faced concrete, as a new type of concrete emerging in recent years, has received more and more attention because of its unique concrete texture and color. [0003] Fair-faced concrete, also known as decorative concrete, gets its name because of its great decorative effect. It belongs to one-time pouring molding, without any external decoration, and directly uses the natural surface effect of cast-in-place concrete as the finish. The surface is smooth and smooth, the color is uniform, the edges and corners are clear, and there is no damage or pollution. Because there are many tiny pores inside the concrete, it is...
