Abstract

The invention relates to the field of water proofing of metal roofs and particularly discloses a flash rust-proof acrylic roof waterproof coating which is prepared from, by weight, the following raw materials: 30-50 parts of an acrylic emulsion, 25-60 parts of antirust slurry, 1-5 parts of a plasticizer, 0.3-5 parts of a dispersing agent, 0.1-1 part of a defoaming agent, 0.1-1 part of a base material wetting agent, 0.1-2 parts of an anti-flash rust additive, 1-4 parts of a film forming assistant, 3-10 parts of water, 0.01-0.5 part of cellulose ether, 0.1-0.5 part of a bactericide, 0.01-0.5 part of a coupling agent and 0.01-0.5 part of a pH adjusting agent. The flash rust-proof waterproof effect of the roof waterproof coating with a flash rust-proof function is longer lasting than that of acommon metal roof waterproof coating, the anti-ultraviolet effect is good, and the service life of a base material is prolonged. The waterproof coating has high elongation rate, good elasticity, strong base layer deformation resistance, the capability of shielding cracks, water proofing and breathability.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to an anti-flash rust acrylic roof waterproof coating and a preparation method thereof. Background technique [0002] For the waterproof treatment of metal roofs, the requirements are different according to the degree of newness and oldness of the metal surface. Generally, it is divided into two situations: one is the steel structure building that has been used for more than 2 to 3 years, and the metal surface of the roof has been used. In this case, the waterproofing of the metal surface should adopt the process of antirust and anticorrosion first, and then waterproof construction; the other is a new steel structure building or a building using aluminum plate or galvanized plate as the roof panel. The condition of the metal surface is very good, and it can be directly waterproofed after the surface is cleaned and painted with metal surface treatment agent. At present, the tra...
