A kind of antibacterial antifungal polymer modified spraying asphalt waterproof coating and using method thereof

Abstract

The invention provides antibacterial and moldproof polymer modified spray asphalt waterproof paint and an application method thereof. The paint is composed of a component A and a component B. The component A is prepared from, by weight, 90-120 parts of anionic emulsified asphalt, 40-90 parts of polymer emulsion, 0.5-5 parts of a thickening agent and 10-60 parts of filler. The component B is prepared from, by weight, 100 parts of water, 5-15 parts of a curing agent and 0.5-5 parts of an antibacterial agent. The invention further provides the application method of the antibacterial and moldproof polymer modified spray asphalt waterproof paint. The antibacterial and moldproof polymer modified spray asphalt waterproof paint has high ductility, high resilience and high adhering strength, is antibacterial and moldproof, excellent in low-temperature performance and high in construction speed and can be closely connected with a basic layer, and influences of deformation of the basic layer on the waterproof performance of a material can be effectively resisted; meanwhile, the situation that bacteria are bred on the surface of a coating film, and the coating function of a waterproof layer is damaged can be effectively prevented, and the possibility that an antibacterial agent has secondary pollution on water is reduced.

Description

technical field [0001] The invention relates to a polymer modified spraying bitumen waterproof coating and a preparation method thereof, in particular to an antibacterial and antifungal polymer modified spraying bitumen waterproof coating and a preparation method thereof. Background technique [0002] With the rapid development of my country's economic construction, especially infrastructure, the demand for waterproof materials is increasing, and the scope of application is also expanding rapidly. Polymer modified asphalt has excellent waterproof performance, good elasticity, strong weather resistance, fatigue resistance, aging resistance, etc., and has the advantages of reliability and economy. It is widely used in basement floors, side walls, subways, tunnels, and roofs , landfill and other anti-seepage and waterproof projects. However, with the improvement of people's living standards and the vigorous development of industrial industries, the problem of eutrophication of...

Problems solved by technology

[0003] At present, polymer-modified rubber asphalt waterproof coatings contain high molecular polymers. When they are immersed in eutrophic groundwater for a long time, bacteria and algae may attach to the waterproof layer, which will cause the waterproof coating to be eroded, and even occur. Biodegradation causes leakage and loses waterproof effect

For example, CN201210500017.4 discloses the special spraying quick-setting rubber waterproof coating for sewage treatment plants. The spraying quick-setting rubber waterproof coating has the effect of preventing microbial growth by adding an anti-fungal agent to the asphalt component, but this invention is to apply the anti-mildew If the antifungal agent is directly added to the anionic asphalt emulsion component, it will easily lead to the instability of the product, and the antifungal agent directly contacts the external water layer in the asphalt emulsion component, which may cause secondary pollution of the water body
