Abstract

The invention relates to the field of coatings, and discloses a facade anti-skid waterproof coating composition and application thereof, and a coating and a preparation method and application thereof. The coating composition contains the following components which are stored independently or stored in a mixed manner: 40-65 wt% of an SBS modified asphalt emulsion, 20-40 wt% of an anionic emulsion, 8-16 wt% of an acrylic acid modified polyurethane emulsion, 3-8 wt% of water, 0.3-0.8 wt% of a thickening agent and 0.3-1.0 wt% of an auxiliary agent, wherein the thickening agent is composed of a thickening agent I and a thickening agent II in a weight ratio of (1-5): 1. The coating composition provided by the invention has the advantages of water-based environmental protection, sagging resistance of a vertical surface, high bonding strength with a base surface, high stripping and shearing strength when compounded with an asphalt coiled material, and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a facade anti-skid waterproof coating composition and its application, a coating and its preparation method and application. Background technique [0002] With the increasing demand for housing in cities, the use of underground space in modern buildings is becoming more and more common, and the facades or side walls of the underground parts are getting higher and higher, and such facades or side walls are in direct or indirect contact with the groundwater layer. Key parts of waterproof construction. [0003] The façade waterproofing of the underground part generally adopts multi-layer waterproofing materials, and most of them are constructed with coiled materials and coatings. Ordinary waterproof coatings are easy to accumulate on the lower part of the facade, resulting in thin top and bottom thick, uneven thickness, and affect the waterproof effect. Ordinary coatings are used in combin...
