Abstract

The invention belongs to the technical field of waterproof coatings, and proposes a high-performance polymer modified asphalt waterproof coating. The coating is composed of the following components, in parts by weight: 30-60 parts of emulsified asphalt, 10-30 parts of pre-vulcanized rubber latex, 5-15 parts of diatomaceous earth, 10-30 parts of a filler, 0.2-1 part of lignocellulose, 0.1-1 part ofnano kaolin, 2-7 parts of polynonylidene urea, 5-20 parts of water, 0.2-2 parts of a compatibilizer, 0.2-0.5 part of an antifoaming agent, 0.3-1 part of a thickening agent, and 0.2-1 part of a preservative. The preparation method comprises the following steps: firstly, adding the compatibilizer, the antifoaming agent, the lignocellulose, the diatomaceous earth, the filler and the preservative into the water, performing uniform mixing, adding the thickening agent to obtain a pre-dispersion, sequentially adding the pre-vulcanized rubber latex and the polynonylidene urea into the emulsified asphalt, performing uniform mixing, slowly adding the pre-dispersion, and performing uniform mixing to obtain the coating. Through the above technical solution, the coating and method provided by the invention solve the problems that a polymer modified asphalt waterproof coating in the prior art has a complicated production process, low strength and poor aging resistance.

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 cementitious material, and it is an indispensable material in civil engineering construction. It is widely used in construction, highway, bridge and other projects. Commonly used asphalt modifiers are classified into polymer modification and inorganic substance modification. Polymer modifiers include SBS, SBR, PE, EVA, etc., and inorganic modification materials include diatomaceous earth. Polymer-modified bitumen waterproof coating is a solvent-based or water-emulsion waterproof coating configured with asphalt as the base material. Solvent-based coatings are not environmentally friendly and their development is hindered; water-emulsion bitumen waterproof coating refers to the use of petroleum asphalt in a che...
