Abstract

The invention discloses a metal roof rustproof waterproof repairing paste, which comprises, by weight, 65-70 parts of water, 2.0-4.0 parts of an aqueous pigment dispersing agent, 8-18 parts of ash calcium powder, 8-18 parts of titanium dioxide, 60-90 parts of zinc phosphate, 25-50 parts of aluminum tripolyphosphate, 450-600 parts of an emulsion, 250-350 parts of heavy calcium powder, 5.5-8.5 partsof anti-flashrust aid, 3.0-5.0 parts of a defoamer, 2.0-3.5 parts of an anticorrosion agent, and 4.0-6.0 parts of a rheological aid. According to the present invention, the metal roof rustproof waterproof repairing paste can form the firm protection layer using iron phosphate as the main body, and the protection layer is densely passivated and insoluble in water so as to provide good anti-rust effect; and the emulsion has advantages of good elasticity, good flexibility and good weather resistance, cannot subjected to thermal expansion and cold contraction, can resist crack, and can form the dense hydrophobic film during the drying so as to provide good waterproof effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an antirust and waterproof repair paste for metal roofs. Background technique [0002] At present, after the metal roof is exposed to wind, sun and rain, the protective layer of the roof will be glued off, then corroded and rusted, and then damaged and leaked. In the prior art, the damaged part is generally painted with anti-rust paint first, and then It is generally necessary to hire professional people to make iron patches, which is time-consuming and labor-intensive. Contents of the invention [0003] The invention proposes a metal roof antirust and waterproof repair paste, which can prevent the appearance of rust spots in the early stage of drying due to the anti-flash rust additive, and has a strong association with ferric ions due to zinc phosphate and aluminum tripolyphosphate. It can form a solid protective layer with iron phosphate as the main body. The den...
