Abstract

The invention provides aqueous anti-rust metal primers, and in particular relates to microspheric ion exchange flash-rust-resistant anti-rust metal primer and a preparation method thereof. The primeris prepared from polyacrylic emulsion, polymer emulsion of a hollow structure, a coalescing agent, a thickening agent, a pH regulator, a flash-rust-resistant agent, a body filler, microspheric calcium-ion-containing silica gel, strontium phosphate, bentonite and water. The environmentally friendly anti-rust metal primer provided by the invention has excellent salt fog resistance and flash rust resistance; the film density is excellent, and the dry film of 0.5 mm can bear a water pressure of 0.3MPa for 30 minutes; the adhesive force is extremely high, and the national standard of automotive anti-rust primers can be reached; the content of prohibited substances is far lower than the content required in relevant laws and regulations.

Description

technical field

[0001] The invention relates to a metal antirust primer, in particular to a microspherical ion exchange anti-flash rust and antirust metal primer and a preparation method thereof. Background technique

[0002] The loss caused by metal corrosion to human beings is staggering, and the global economic loss caused by corrosion is about 1 trillion US dollars every year. According to the latest statistics of relevant departments, the economic loss of corrosion in my country is as high as 280 billion yuan, accounting for about 4% of the gross national product (GNP), and about 30% of steel is corroded and scrapped every year. Corrosion is not only causing huge economic losses, but also stimulating the development of anti-corrosion coatings. At present, countries all over the world have competed to develop a variety of corrosion coatings with good performance, which are widely used in various corrosion environments and have produced obvious economic benefits.
