Abstract

The invention discloses a waterproof architectural coating with excellent mechanical property. The architectural coating comprises the following raw materials in parts by weight: 10-20 parts of phenolic resin, 20-30 parts of isophthalic acid polyester resin, 5-10 parts of diphenyl ether formaldehyde resin, 10-20 parts of perchloroethylene, 10-20 parts of styrene, 1-10 parts of ethylene glycol ether, 5-15 parts of modified wheat protein, 2-4 parts of nano titanium dioxide, 1-2 parts of barite powder, 1-5 parts of nano silicon dioxide and 2-6 parts of diaminodiphenyl methane. The architectural coating disclosed by the invention has good mechanical property, excellent film forming property and good waterproof property.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof architectural coating with excellent mechanical properties. Background technique [0002] The coatings used in construction are mainly divided into waterproof coatings, which have the function of waterproof and anti-seepage. In practical applications, the impact of acid rain is increasing, and the external coating on the building needs to have excellent waterproof performance, and at the same time, the mechanical properties and film-forming properties are also high. At present, the coating exposed to the outermost layer of the building is damaged to a greater extent under the action of acid rain, which reduces the protection ability of the coating to the building body. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a waterproof architectural coating with excellent mechanical properti...
