Water-based ultra-thin fireproof coating and preparation method thereof

Abstract

The invention provides a water-based ultra-thin fireproof coating, which comprises the following components in percentage by weight: 20-30% of chloroethylene-vinylidene chloride polyemulsion, 5-15% of benzene acrylic emulsion, 5-8% of expandable graphite powder, 5-10% of rutile type titanium dioxide, 2-4% of environment-friendly zinc phosphate, 4-5% of precipitated barium sulphate, 2-4% of corrosion inhibitor, 5-8% of aluminum hydroxide, 2-4% of antimonous oxide, 2-4% of water-based chlorinated paraffin, 1-3% of aluminum silicate fiber, 5-10% of ammonium polyphosphate (APP), 3.5-7% of pentaerythritol (PER), 1.5-2.4% of melamine (MEL), 0.2-0.3% of water-based disperser, 0.1-0.2% of water-based defoamer, 0.1-0.2% of water-based foam inhibitor, 1-2% of hydrated magnesium silicate, 0.5-1% of water-based thickening agent, 0.5-1% of neutralizer, 0.5-1% of flash-rust inhibitor, 1-2% of coalescing agent, 0.1-0.2% of water-based wetting agent, and 7.0-9.0% of deionized water. The dry speed of the water-based ultra-thin fireproof coating disclosed by the invention is rapid; the fireproof ability can be above 2 h; and the water-based ultra-thin fireproof coating has very excellent binding force and antiseptic property to rusty substrates.

Description

technical field [0001] The invention relates to the field of paint production, in particular to a water-based ultra-thin fireproof paint and a preparation method thereof. Background technique [0002] As the country's environmental protection requirements become more and more stringent, and with the implementation of the new environmental protection law, the marketization of water-based coatings is imperative. At present, the traditional oil-based fire-resistant coating is still used to protect the metal surface, which has caused great pollution to the environment and brought great harm to the body of the paint personnel. Therefore, a water-based environmentally friendly fire-resistant coating has been developed. It is imperative. Contents of the invention [0003] The invention proposes a water-based ultra-thin fireproof coating and a preparation method thereof. The product has fast drying speed, a fireproof ability of more than 2 hours, and excellent binding force and a...
