Water-based anti-rust paint and preparation method thereof

Abstract

The invention provides a water-based anti-rust paint and a preparation method thereof. The water-based anti-rust paint contains the following raw materials in parts by weight: 20-60 parts of water-based alkyd resin, 0.1-0.5 part of water-based coating multifunctional auxiliaries, 0.3-0.8 part of dispersant, 0.1-0.3 part of defoaming agent, 0.1-1 part of substrate wetting dispersant, 0.1-1 part of flash rust-proofing agent, 3-10 parts of 1250-mesh talc powder, 5-15 parts of zinc phosphate, 5-15 parts of anatase titanium dioxide, 0.1-1 part of carbon black, 10-30 parts of barium sulfate, 0.1-1 part of anti-settling agent, 1-10 parts of rheological aids, 0.1-1 part of thickener, 1-10 parts of auxiliaries, and 2-25 parts of water. The water-based anti-rust paint achieves the national requirement on environment-friendly paint, is proper in price and high in quality, has excellent corrosion resistance and weather resistance, and is stable in chemical properties and thermal storage performance.

Description

technical field [0001] The invention belongs to the field of chemical production and manufacture, and in particular relates to a water-based antirust paint and a preparation method thereof. Background technique [0002] Water-based anti-rust paint is formulated with water as the dispersion medium, using multiple anti-rust mechanisms such as physics and chemistry, and formulated according to chemical principles such as chemical transformation, network and reaction. It is the best replacement product for traditional anti-rust primers. Widely used in anti-corrosion protection of various automobiles, ships, grids, machinery manufacturing, containers, railways, bridges, boilers, steel structures, petrochemical equipment, etc., it is incomparable to solvent-based paints. Existing water-based antirust paints do not have excellent corrosion resistance and weather resistance, are chemically unstable, and have unstable thermal storage properties.
