Abstract

The invention relates to an antibacterial algae adhesion coating for concrete. The antibacterial algae-resistant coating for the concrete is prepared from sodium silicate, potassium silicate, a surfactant, OIT, Diuron, a polymer emulsion, a defoaming agent, a coalescing agent, superfine cement powder, an early strength agent and a water reducing agent. The antibacterial and algae-resistant coating for the concrete acts on the surface of the concrete in an over-spraying construction mode, and a compact crystal structure is generated on the surface of the concrete, so that a compact nano protective layer is formed, the smoothness is high, and the adhesion of molds and algae can be effectively inhibited, so that the concrete has the characteristics of resisting common germs, molds and algae, inhibiting drug-resistant germs, resisting bacteria and algae and the like. The efficient and lasting functions are realized.

Description

technical field [0001] The invention relates to a coating for antibacterial algae attached to concrete, which belongs to the technical field of concrete coatings. Background technique [0002] Algae, which are abundant in nature, can absorb moisture from the air and keep it in the surrounding space for a long time, thus causing great harm to coatings such as outdoor buildings and underground works exposed to natural conditions. Although the existing traditional coatings have a certain effect in controlling antibacterial and anti-algae, algae will still adhere to a certain extent. In order to further solve the problem of bacteria and algae intrusion and adhesion, the existing coatings are further improved. SUMMARY OF THE INVENTION [0003] (1) Technical problems to be solved [0004] In order to solve the above problems of the prior art, the present invention provides a coating with antibacterial algae attached to concrete. [0005] (2) Technical solutions [0006] In or...
