Abstract

The invention discloses an aqueous elastic fluorocarbon building coating covering large cracks, and a preparation method and an application thereof. A raw material formula of the aqueous elastic fluorocarbon building coating comprises, by mass, 30.0-60.2% of an aqueous elastic fluorocarbon emulsion, 2.0-3.0% of hydroxyethyl cellulose, 7.0-14.0% of an inorganic pigment, 10.0-35.0% of a filler, 5.0-7.0% of a collagen fiber, 1.1-1.8% of a glass fiber short cut protofilament, 1.1-3.2% of a wetting dispersant, 0.4-1.2% of a multifunctional assistant, 0.3-0.5% of an antifoaming agent, 0.3-4.2% of a bactericide, 0.2-3.2% of a thickening agent, 0.8-1.2% of a film forming assistant, 1.6-7.0% of an antifreeze agent and 10.0-25.0% of water. The aqueous elastic fluorocarbon building coating can cover 4mm or more cracks of building walls, and is safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based elastic fluorocarbon architectural coating covering large cracks, a preparation method and application thereof. Background technique [0002] Modern building adhesive materials will produce small cracks due to shrinkage after drying, which will cause great safety hazards to project management. The exterior walls of buildings are also cracked due to the perennial cold winter and summer heat. At the same time, with the extension of the service life, the building will sink as a whole. The cracking of the building wall will become more and more serious, seriously affecting the appearance quality of the building. Although there are already elastic architectural coating products on the market that can compensate for small cracks, they generally can only cover small cracks of ≤0.4mm. At the same time, with the prolongation of the service life of the building and the harsher enviro...
