Problems solved by technology

[0002] At present, the acrylic coatings used on the market for building exterior walls are generally only used for decoration, and the effect is good, but the toughness and waterproof performance are poor, and the coating film is easy to crack. The rainwater will seep into the outer wall of the building, corrode the wall surface, and seriously endanger people's life safety

Abstract

The invention discloses high-toughness building exterior wall coating, made from the raw materials, by weight: 50-60 parts of polyurethane-polyacrylate composite emulsion, 30-40 parts of silica sol, 1-6 parts of modified composite emulsion, 2-6 parts of dodecyltrichlorosilane, 0.5-1.5 parts of octylphenol polyoxyethylene, 0.5-1.5 parts of fatty acid sorbitan, 3-8 parts of asbestos powder, 5-15 parts of lignin, 2-8 parts of kaolin, 1-5 parts of graphene, 1-4 parts of hydroxyethyl cellulose, 1-2 parts of polyvinylidene fluoride micro-powder, 1-2 parts of ammonia water, 1-2 parts of perchloroethylene, 1-2 parts of a wetting agent, 1-2 parts of a defoaming agent, and 20-45 parts of water. The building exterior wall coating with high toughness is excellent in coating toughness and waterproof property.

Description

technical field [0001] The invention relates to the technical field of exterior wall paint, in particular to a building exterior wall paint with excellent toughness. Background technique [0002] At present, the acrylic coatings used on the market for building exterior walls are generally only used for decoration, and the effect is good, but the toughness and waterproof performance are poor, and the coating film is easy to crack. Rainwater just infiltrates in the exterior wall of building, corrodes wall surface, can seriously endanger people's life safety. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a building exterior wall coating with excellent toughness, the coating film has excellent toughness and excellent waterproof performance. [0004] A kind of architectural exterior wall paint with excellent toughness proposed by the present invention, its raw material comprises by weigh...
