High-strength antibacterial environment-friendly water-permeable brick and preparation method thereof

Abstract

The invention discloses a high-strength antibacterial environment-friendly water-permeable brick and a preparation method thereof. The water-permeable brick comprises the following components in partsby weight: 80-100 parts of polymer fiber porous concrete, 40-60 parts of building waste residues, 10-20 parts of hollow microbeads, 3-9 parts of nano titanium dioxide, 2-6 parts of nano silicon dioxide, 3-10 parts of nano tourmaline, 2-4 parts of modified activated carbon, 1-3 parts of modified graphene oxide, 2-8 parts of zirconia fibers and 2-6 parts of an antibacterial agent. According to thehigh-strength antibacterial environment-friendly water-permeable brick disclosed by the invention, an antibacterial agent taking carboxymethyl chitosan as a main component is added, so that the water-permeable brick has a balanced sterilization effect, damage to the environmental is small, and the lasting time of the sterilization effect is long. The water-permeable brick is simple in preparationmethod, has the advantages of excellent compressive strength, wear resistance and corrosion resistance and high strength, is not easily damaged, and has the advantages of adsorbing pollutants in waterand inhibiting and resisting bacteria. Environmental protection performance is good, and popularization and use are convenient.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a high-strength antibacterial and environment-friendly permeable brick and a preparation method thereof. Background technique [0002] With the intensification of urbanization, the urban surface is gradually being covered by buildings and various concrete and other water-repelling materials, and the proportion of impermeable areas has increased significantly, and the coverage rate in some areas has exceeded 80%. As the drainage capacity of cities is getting worse and worse, when many cities encounter heavy rains, the rainwater on the roads cannot seep quickly, which can easily cause urban waterlogging. In order to solve the problem of urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance, a new green and environmentally friendly building material product-permeable bricks emerged as the times require and have deve...

Problems solved by technology

However, in the dark and humid permeable bricks, various microorganisms such as bacteria are easy to breed. The growth and reproduction of bacteria and other microorganisms, and the accumulation of a large number of extracellular polymers can easily cause blockage of the permeable brick aperture, affecting the permeable effect of the permeable brick.
