Abstract

The invention relates to a preparation method of high-performance water-based anticorrosion paint. The high-performance water-based anticorrosion paint comprises 30-60 parts of inorganic material resin, 0.5-30 parts of polyaniline-based nano composite material, 0-30 parts of curing agent, 0.1-1 part of defoaming agent, 0.1-1 part of dispersant and 0.1-1 part of leveling agent. Since the high-performance water-based anticorrosion paint does not contain organic resin or organic solvent, the paint has the advantages of heat resistance, wear resistance, weather resistance, oil resistance, fire resistance and environmental protection; the paint also has the advantages of simple preparation technique, strong binding force with metal, and low cost, can be cured at normal temperature, and can be widely used for corrosion protection in the fields of aviation, navigation, chemical engineering, electronics and the like.

Description

technical field [0001] The invention relates to the field of preparation of water-based anti-corrosion coatings, in particular to a preparation method of a high-performance water-based anti-corrosion coating using polyaniline-based nano-composite materials as anti-corrosion agents and inorganic materials as matrix resins. Background technique [0002] According to statistics, metal equipment and materials scrapped due to corrosion are equivalent to 1 / 3 of the annual output of metals, resulting in huge losses. Therefore, the research on anti-corrosion coatings has always been an important topic in the metal protection and coatings industry. Due to the limitations of its own material properties and technology, traditional coatings often have unsatisfactory corrosion protection effects on metal substrates, and a considerable part of coatings contain toxic substances such as lead or chromate, which causes environmental pollution during preparation and construction. This is not c...
