Waterborne over-rust waterproof and rustproof paint for color steel tile

Abstract

The invention relates to waterborne over-rust waterproof and rustproof paint for a color steel tile. The waterborne over-rust waterproof and rustproof paint comprises the following components in parts by weight: 30-47 parts of a silicone acrylate emulsion, 1-5 parts of a penetrating agent, 0.3-0.5 part of a flash rust preventer, 10-15 parts of aluminum dihydrogen tripolyphosphate, 5-10 parts of zinc oxide, 5-10 parts of rutile titanium dioxide, 0.3 part of a dispersing agent and 10-20 parts of deionized water. The waterborne over-rust waterproof and rustproof paint has the beneficial effects as follows: 1, the silicone acrylate emulsion is used for substituting acrylic resin and styrene-acrylic resin in the original scheme, and the silicone acrylate emulsion has better weather resistance, water resistance, stain resistance, good adhesion to a substrate, special silane grafting performance and significant coating water white resistance; 2, due to addition of the flash rust preventer, the flash rust problem of the waterborne paint is solved; 3, due to addition of the penetrating agent, the problem that after the paint is sprayed onto a surface, the paint cannot penetrate into the surface is solved, so that floating rust is not required to be removed and construction can be performed in the presence of the floating rust; 4, zinc phosphate is replaced by the aluminum triphosphate, so that the rustproof effect is more long-lasting.

Description

technical field [0001] The invention relates to a coating composition, in particular to a water-based rust-bearing waterproof and anti-rust paint for color steel tiles. Background technique [0002] As a building steel plate, color steel tiles are widely used in industrial and civil buildings, warehouses, characteristic buildings, roofs and interior and exterior wall decoration of large-span steel structures. Because color steel tiles are exposed to the sun and rain for a long time, the paint on the surface of color steel plates is easy to age and peel off. , causing color steel tiles to rust and leak, affecting the service life. Most manufacturers stop production to replace the color steel tiles, or do waterproofing on the color steel tiles, replace the color steel tiles, stop production, and the replaced steel tiles need to be re-smelted, causing pollution to the environment. Traditional water-based anti-rust paints on the market need to clean up rust spots, which is labo...

[0002] As a building steel plate, color steel tiles are widely used in industrial and civil buildings, warehouses, characteristic buildings, roofs and interior and exterior wall decoration of large-span steel structures. Because color steel tiles are exposed to the sun and rain for a long time, the paint on the surface of color steel plates is easy to age and peel off. , causing color steel tiles to rust and leak, affecting the service life

Most manufacturers stop production to replace the color steel tiles, or do waterproofing on the color steel tiles, replace the color steel tiles, stop production, and the replaced steel tiles need to be re-smelted, causing pollution to the environment

The traditional water-based anti-rust paint on the market needs to clean the rust spots, which is labor-consuming and time-consuming; while the same kind of acrylic acid-based waterproof paint cannot prevent rust
