Problems solved by technology

The production of bryophytes not only affects the appearance of their parasites, but also destroys the visual aesthetics of the parasites. The slimy layer formed by the slimy bodies secreted by bryophytes can also reduce the friction coefficient of the surface of their parasites, increase the risk of pedestrian travel, and cause death, After decay, all kinds of decay products will also harm the surrounding water body and the atmospheric environment. At the same time, the decomposition of the roots of moss algae produces carbonic acid, humic acid and various organic acids to reduce the pH value of the surface layer of the parasite, which poses a hazard to the durability of concrete.
[0003] There are many measures for the prevention and control of bryophytes at home and abroad. Most of the control measures are aimed at duckweed and other water bryophytes in water. There are few measures for the control of bryophytes related to pavement concrete, and the existing bryophytes control effects are not good. Moss on the surface of concrete Algae not well controlled

Abstract

The invention discloses a moss and algae inhibitor for concrete. The moss and algae inhibitor for the concrete is prepared by combining nanometer titanium dioxide, silane, isothiazolinone, a nano-silver sterilizing agent, alloy powder, a modified nanometer sodium silicate hydrophobic material, water-based nanometer inorganic mineral emulsion (polysiloxane) and a water-based curing agent accordingto a certain ratio. The moss and algae inhibitor for the concrete has the advantages of high algae killing efficiency and durable algae killing effect, can be doped into or coated on the concrete of wet and rainy areas and waterfront coastal areas, and can inhibit propagation of the moss and algae on the surfaces of concrete structures effectively for a long time.

Description

technical field [0001] The invention belongs to the technical field of chemical building materials, in particular to a chemical inhibitor capable of long-term and effectively inhibiting the growth of bryophytes on the surface of concrete structures and structures. Background technique [0002] Bryophyta is a general term for green algae such as Spirogyra, Hydrocystis, Diptera, and Transplatinum, and blue-green algae such as Microcystis and Cystococcus, and mosses. The production of bryophytes not only affects the appearance of their parasites, but also destroys the visual aesthetics of the parasites. The slimy layer formed by the slimy bodies secreted by bryophytes can also reduce the friction coefficient of the surface of their parasites, increase the risk of pedestrian travel, and cause death, After decay, all kinds of decay products will also harm the surrounding water body and the atmospheric environment. At the same time, the decomposition of the roots of moss algae pro...
