Abstract

The invention belongs to the technical field of waterproof coatings, and proposes a high-performance polymer-modified asphalt waterproof coating, which consists of the following components in parts by weight: 30-60 parts of emulsified asphalt, 10-30 parts of pre-vulcanized rubber latex, and 5 parts of diatomite ~15 parts, filler 10~30 parts, lignocellulose 0.2~1 part, nano kaolin 0.1~1 part, polynonylidene urea 2~7 parts, water 5~20 parts, compatibilizer 0.2~2 parts, disinfectant 0.2 to 0.5 parts of foaming agent, 0.3 to 1 part of thickener, and 0.2 to 1 part of preservative. Add water, mix evenly, add thickener to obtain pre-dispersion, then add pre-vulcanized rubber latex and polynonylurea to emulsified asphalt in turn, mix evenly, slowly add pre-dispersion, mix evenly to obtain. Through the above technical proposal, the problems of complex production process, low strength and poor aging resistance of the polymer modified asphalt waterproof coating in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, and relates to a high-performance polymer modified asphalt waterproof coating and a preparation method thereof. Background technique [0002] Asphalt is a brown or dark brown organic gelling material, which is an indispensable material in civil engineering construction. It is widely used in construction, highway, bridge and other projects. Commonly used asphalt modifiers are divided into polymer modification and inorganic substance modification. Polymer modifiers include SBS, SBR, PE, EVA, etc., and inorganic modification materials include diatomaceous earth. Polymer modified asphalt waterproof coating is a solvent-based or water-emulsion waterproof coating based on asphalt. The solvent-based coating is not environmentally friendly and its development is hindered; Under the action of an emulsifier, it is dispersed in water to form a coating composed of a stable water dispersion, and...
