Problems solved by technology

[0004] (1) When dealing with detailed nodes, the positive charge on the cement surface and the coagulant component on the surface of the quick-setting waterproof membrane when repairing defects after construction will cause the existing brush-type waterproof coating to quickly condense into lumps. These lumps not only affect the appearance, but also The weak point of waterproofing
[0005] (2) After the conventional brushing type rubber asphalt waterproof coating is painted, the brushing tools cannot be washed with clean water. Clean water will destroy the balance of the system and cause the paint to condense. , so the brushing tools of conventional brushing type waterproof coatings are basically disposable and difficult to reuse

Abstract

The invention provides emulsified asphalt, a preparation method of the emulsified asphalt, a brushing type rubber asphalt waterproof coating and a preparation method of the brushing type rubber asphalt waterproof coating. The emulsified asphalt comprises the following components by the mass percentage: 60%-63% of petroleum asphalt, 0.3%-2% of a fatty alcohol-polyoxyethylene ether sulfate emulsifier, 0.1%-0.5% of a pH value regulator, 0.1%-0.5% of a stabilizing agent, and deionized water. According to the technical scheme of the invention, the emulsified asphalt with good stability is prepared;the emulsifier contains an ethoxy group and a sulfonic group, and the anion and non-ion characteristics are realized at the same time; when meeting cations such as calcium ions and the like, the emulsified asphalt is not easy to condense, rubber latex with good stability is compounded by the emulsified asphalt, lumps are not easy to form during brushing, the waterproof construction quality is improved, the attractiveness is improved, and a brushing tool can be directly cleaned by clean water after being used up; the emulsified asphalt can be repeatedly used, resources are saved, and waste isreduced.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to emulsified asphalt, a preparation method of emulsified asphalt, a brushing type rubber asphalt waterproof paint and a brushing type rubber asphalt waterproof paint preparation method. Background technique [0002] In recent years, spraying quick-setting rubber asphalt waterproof coating has developed rapidly due to its characteristics of fast construction, full stickiness, and good waterproof effect. Spraying quick-setting rubber asphalt waterproof coating is convenient and quick for large-area waterproof construction, but it cannot be used directly. For detailed node treatment and defect repair after waterproofing construction, it is necessary to use brush-type rubber asphalt waterproof coating. [0003] The formula composition of commonly used brushing rubber asphalt waterproof coatings is basically the same as that of spraying quick-setting rubber asphalt waterproof coatings....
