Abstract

The invention discloses a sewage pool waterproof layer construction method. The sewage pool waterproof layer construction method comprises following steps of firstly, base layer treatment; secondly, waterproof layer spraying; thirdly, repeating of the step two for two to three times. During spraying construction, the component A and the component B are rapidly mixed and cured, an antibacterial agent, silver powder and zinc powder are wrapped in a waterproof layer, effective antibiotic constituents are gradually released from a coating film, the slow releasing effect is achieved, it is effectively ensured that the antibiotic constituents cannot be easily washed by flow water, it is ensured that microorganisms and algae cannot be attached and bred on a waterproof coating, and the possibilitythat the antibacterial agent generates the secondary pollution to the water is reduced. Nanometer silver powder and the antibacterial agent in the formula can effectively restrain bacterium growth, the microorganisms can be prevented from being attached and bred on the surface of the waterproof coating, biodegradation of the waterproof material is prevented, antibiosis and mildew gathering prevention of waterproof layer failures can be avoided, and the nano zinc powder can further restrain bacteria, remove odor and prevent mildew.

Description

technical field [0001] The invention belongs to the technical field of rubber coatings, and in particular relates to a construction method for a waterproof layer of a sewage pool. Background technique [0002] With the improvement of people's living standards and the vigorous development of industrial industries, the problem of eutrophication of water resources caused by sewage is becoming more and more serious. When artificial lakes, pools, waste disposal sites and sedimentation tanks are immersed in eutrophic groundwater for a long time, bacteria and algae may attach to the waterproof layer, resulting in erosion of the waterproof coating and even biodegradation. Leakage, loss of waterproof effect. Therefore, it is urgent to produce a special waterproof and anti-corrosion coating product that can be in contact with nutrient water for a long time. Contents of the invention [0003] In order to solve the technical problems in the above-mentioned prior art, the technical s...
