Embodiment 1

[0043] Component A: Pump 60# special asphalt for waterproof materials into the asphalt tank and heat to 160°C~180°C, add 3% APP, stir at high speed for 2 hours, then add 4% epoxy resin E-51, 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 then set aside. Pump hot water at 60°C into the soap tank, add tall oil anionic emulsifier (sulfonated tall oil soap or sulfosuccinic acid) 1%, AEO-9 0.02% and ethylenediamine 0.6% , 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 form a modified emulsified asphalt emulsion with a concentration of about 60%, and 25% neoprene latex (solid content 60%) is added to the emulsion, and then Put in 0.4% of Hexinglu brand anti-ultraviolet agent UV477 and 0.5% of Hexinglu brand antioxidant 55 in sequence. During the feeding ...

Embodiment 2

[0046] Component A: Pump 70# heavy duty asphalt into the asphalt tank and heat to 150°C-170°C, add 3% APAO, stir at high speed for 2 hours, then add 4% epoxy resin E-44, stir for 30 minutes and then pass through Colloid mill grinding, the prepared polymer modified asphalt material was stirred for 2 hours to defoam and set aside. Pump hot water at 60°C into the soap tank, add 1% of tall oil anionic emulsifier (sodium abietate or sulfonated rosin), 0.02% of AEO-9 and 0.4% of ethylenediamine, and use NaOH Adjust the pH to 11 to make soap. Put the prepared polymer modified asphalt and soap solution through a high-speed shearing machine to make a modified emulsified asphalt emulsion with a concentration of about 60%, add 25% neoprene latex to the emulsion, keep stirring for 20 minutes, and then stop Stir, add a small amount of defoamer and stand still for 10 minutes for defoaming treatment, and then the finished product is loaded into barrels.

Abstract

The invention discloses a two-component high-polymer modified water-emulsion asphalt-based waterproof paint resisting acid, alkali and salt environment, 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 APAO, chloroprene rubber, SBS rubber, epoxy resin and the like, and multiple functional agents such as an anti-ultraviolet agent and the like 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 salt water resistance is kept for 240 h without abnormity, the salt spray resistance is kept for 1000 h without foaming and shedding, the acid resistance is kept for 168 h without abnormity, the alkali resistance is kept for 168 h without abnormity, no flow happens at a high-temperature of 100 DEG C, no embrittlement happens at a low temperature of -20 DEG C, the elasticity recovery rate reaches up to 90%, and the elongation at break reaches 1000% or more. The paint is an asphalt-based high-molecular waterproof paint resisting acid, alkali and salt.

Description

technical field [0001] The invention belongs to the technical field of waterproof building materials, in particular to a two-component high polymer modified water-emulsion type asphalt-based waterproof paint resistant to acid, alkali and salt environments and a preparation method thereof. Background technique [0002] Asphalt itself is a very good and common waterproof material, and it has good acid, alkali and salt resistance. It has been used in the field of waterproofing for a long time. However, asphalt is easy to flow at high temperature and easy to crack at low temperature. characteristics, which limit the application. Contents of the invention [0003] The present invention aims at the above-mentioned deficiencies of the prior art, and provides a two-component high polymer modified water-emulsion type asphalt-based waterproofing that is not easy to flow at high temperature, not easy to crack at low temperature, and has good acid, alkali and salt resistance, and is r...
