Abstract

The present invention relates to a new paint, which is composed by matching rust-inhibiting primer and high performance weather-resistant top-coat. Paint prime lacquer 3 times and top-coat 2-3 times generally when painting. The main film forming matter is acroid resin and special type modified resin, which improve various mechanical physical properties and weather-resistant properties like adhesive force of the paints greatly. The paint is single modified acroleic acid anti-corrosive paint and composed by acroid resin, modified resin, plasticizer, flexibilizer, antirust pigment, fillers, imported dispersant and anti-settling agent etc., wherein the rust-inhibiting primer has excellent rust protection performance, and the top-coat has excellent aging-resistant characteristic, salt-mist-resistant, water resistant, diluted acid resistant, chemical smog and alternation of wetting and drying with lacquerfilm adamant and adhesive force strong and construction convenient, and coating has no season limitation, can be solidified at low temperature, no longest coating construction interval requirement and good recoatability.

Description

Technical field [0001] The invention relates to an anti-corrosion paint, which is composed of an anti-rust primer and a high-performance weather-resistant top paint. Generally, the primer is painted with 3 coats and the top coat is painted with 2 to 3 coats. In particular, it refers to one-component coatings with modified acrylic resins and special modified resins as the main film-forming substances, which greatly improves the adhesion and other mechanical and physical properties and weather resistance of such coatings. Background technique [0002] In steel structure anti-corrosion engineering, coating has always been its most important, most economical and effective anti-corrosion method. At present, the corrosion of ships and general steel structures is prominently manifested in the destruction of internal structures and parts exposed to atmospheric environments such as sunlight and salt spray. Domestic maintenance of steel structures and cabins mainly use alkyd and epoxy este...
