Problems solved by technology

Due to the short construction period, the project period is usually two years. After the main masonry is completed in the first year, when the roofing project is transferred to October, the temperature is low and the temperature difference is large; and the daily temperature difference in spring and autumn is large, and it melts during the day. , The freezing situation at night lasts for a long time, and the general waterproof coating is a rigid material, which is not suitable for such a harsh working environment; Coil laying is time-consuming and laborious, and the adhesion to the substrate and the ductility of the material itself are not very good

Embodiment 1

[0031] Component A: Pump 100# special asphalt for waterproof materials into the asphalt tank and heat it to 160℃~180℃, pump in 2% aromatic oil, then add 2% SBS rubber and 1% epoxy resin E-51, stir for 30 Minutes later, it was ground by a colloid mill, and the prepared modified asphalt material was stirred and developed for 2 hours, and then used. Pump hot water at 60°C into the soap tank, add 1% of tall oil anionic emulsifier (tal oil or sulfonated tall oil soap or sodium rosinate), 0.02% of AEO-9 and ethylene glycol Amine 0.6%, at the same time use NaOH to adjust the pH value to 11 to make soap. The prepared polymer modified asphalt and soap solution are simultaneously passed through a high-speed shearing machine to form a modified emulsified asphalt emulsion with a concentration of about 60%. Add 25% neoprene latex to the emulsion, and then add 0.4% and Xinglu brand anti-ultraviolet agent UV477 and 0.5% Hexing deer brand antioxidant 55 should be stirred slowly to disperse e...

Embodiment 2

[0034] Component A: Pump 90# heavy traffic asphalt into the asphalt tank and heat it to 160℃~180℃, pump in 3% aromatic oil, then add 2% SBS rubber and 1% epoxy resin E-44, and stir for 30 minutes After grinding by a colloid mill, the prepared modified asphalt material was stirred and grown for 2 hours, and then used. Pump hot water at 60°C into the soap tank, add 1% of tall oil anionic emulsifier (sulfonated succinic acid or sulfonated rosin), 0.02% of AEO-9 and 0.6% of ethylenediamine, and use NaOH adjusts the pH to 11 to make soap. The prepared polymer modified asphalt and soap solution are simultaneously passed through a high-speed shearing machine to form a modified emulsified asphalt emulsion with a concentration of about 60%. Add 25% neoprene latex to the emulsion, and then add 0.4% and Xinglu brand anti-ultraviolet agent UV477 and 0.5% Hexing deer brand antioxidant 55 should be stirred slowly to disperse evenly during the feeding process. After feeding is completed, ke...

Abstract

The invention discloses a high-polymer modified water-emulsion asphalt-based waterproof paint and a preparation method thereof. The paint is prepared by taking high-concentration ultrafine suspension microemulsion anion modified emulsified asphalt, multiple synthetic high-molecular polymers such as cis-1,4-polybutadiene rubber, SBS rubber, epoxy resin and the like, and multiple functional agents as raw materials and mixing by employing a special production technology. When applied, the paint is subjected to mechanical spraying by employing a two-component spray gun, the demulsification coagulation is fast, and after a film is formed, the low-temperature work temperature reaches -30 DEG C and the high-temperature work temperature reaches 100 DEG C, and the elasticity recovery rate reaches 90% or more.

Description

technical field [0001] The invention belongs to the technical field of waterproof building materials, in particular to a polymer-modified water-emulsion type asphalt-based waterproof coating specially used in ultra-low temperature environments in northern alpine regions and a preparation method thereof. Background technique [0002] Waterproof construction in alpine regions, especially roof waterproof construction, is extremely difficult. Due to the short construction period, the project period is usually two years. After the main masonry is completed in the first year, when the roofing project is transferred to October, the temperature is low and the temperature difference is large; and the daily temperature difference in spring and autumn is large, and it melts during the day. , The freezing situation at night lasts for a long time, and the general waterproof coating is a rigid material, which is not suitable for such a harsh working environment; in order to solve the abov...
