Embodiment 1

[0037] Component A: Pump 60# asphalt specially used for waterproof materials into the asphalt tank and heat to 160°C-180°C, add 3% aromatic oil, stir at 80 rpm for half an hour, and then add 3% epoxy resin E-51, After stirring for 30 minutes, it was ground by a colloid mill, and the prepared polymer modified asphalt material was stirred for 2 hours to defoam, and when the temperature dropped to about 150°C, 0.1% BIT preservative Nuosept498, 0.5% BCM antifungal agent and N-3 were added ,4-dichlorophenyl-N`,N`-dimethylurea 0.2%, stir for later use. Pump hot water at 60°C into the soap tank, add sulfonated tall oil soap or tall oil (tall oil anionic slow-cracking emulsifier) ​​1%, 0.02% AEO-9 and 0.6% ethylenediamine , while adjusting the pH value to 11 with NaOH to make soap. The prepared polymer modified asphalt and soap solution are simultaneously passed through a high-speed shearing machine to make a modified emulsified asphalt emulsion with a mass concentration of 60%, and ...

Embodiment 2

[0040] Component A: Pump 60# asphalt into the asphalt tank and heat to 160℃~180℃, put in 2% aromatic oil, stir at 100 rpm for half an hour, then put in 2% epoxy resin E-44, and stir for 30 minutes After being ground by a colloid mill, the prepared polymer modified asphalt material was stirred for 2 hours to defoam, and when the temperature dropped to about 150°C, 0.1% BIT preservative Nuosept498, 0.5% BCM antifungal agent and N-3,4- Dichlorophenyl-N`,N`-dimethylurea 0.2%, stirred for later use. Pump hot water at 60°C into the soap tank, add 1% sulfonated tall oil soap, 0.02% AEO-9 and 0.6% 1,3-propylenediamine, and adjust the pH value to 11 with NaOH at the same time. into soap. The prepared polymer-modified asphalt and soap solution are simultaneously passed through a high-speed shearing machine to make a modified emulsified asphalt emulsion with a mass concentration of 60%. Add 15% neoprene latex, 10% styrene-butadiene latex and 0.5% IPBC antifungal agent, add slowly and k...

Abstract

The invention discloses a microorganism-pollution-resistant asphalt-base high-molecular water-emulsion waterproof paint. The paint is prepared by taking high-concentration ultrafine suspension microemulsion anion modified emulsified asphalt, multiple synthetic high-molecular polymers such as SBS rubber, chloroprene rubber, epoxy resin and the like, a composite anticorrosion mildew-resistant algicide and multiple functional agents as raw materials and mixing by employing a special production technology. Tests show that after a film is formed from the paint, no embrittlement happens at a low temperature of -25 DEG C, no flow happens at a high temperature of 120 DEG C, the elasticity recovery rate reaches up to 90%, and the mildew-resistant and algae-resistant degrees both reach first level.

Description

technical field [0001] The invention belongs to the technical field of waterproof building materials, in particular to an anti-biological asphalt-based polymer water-emulsion waterproof coating and a preparation method thereof. Background technique [0002] The microbial contamination that may occur in the production and storage of coatings is mainly caused by bacteria, which should be solved by adding preservatives, purifying the environment and strict production management. The coating has hydrophilic components, has a certain degree of water absorption, and at the same time contains the nutrients needed by microorganisms, and it is easy to grow mold and algae in a hot and humid environment. Therefore, for coatings, there is an anti-mildew and anti-algae problem, and how to provide an anti-mildew and anti-algae coating has become a technical problem to be solved urgently in this field. Contents of the invention [0003] The present invention aims at the above-mentioned ...
