Graphene added anticorrosion latex paint for outer wall and preparation method thereof

Abstract

The invention discloses a graphene added anticorrosion latex paint for an outer wall. The graphene added anticorrosion latex paint is characterized by being prepared from the following raw materials in parts by weight: 38 to 35 parts of pure acrylic emulsion, 7 to 9 parts of water-based fluorine carbon emulsion, 2 to 3 parts of silicone oil, 20 to 23 parts of rutile titanium dioxide, 5 to 6 parts of graphene, 7 to 9 parts of zeolite, 7 to 9 parts of pearl wool leftovers, 105 to 107 parts of water, 1.5 to 2 parts of asolo-OT, 3 to 4 parts of carrageenan, 2 to 3 parts of ammonium bicarbonate, 0.8 to 1 part of lignocelluloses, and 0.5 to 0.7 part of 1, 2-benzisothiazolin-3-ketone. According to the graphene added anticorrosion latex paint, pure acrylic emulsion and water-based fluorine carbon emulsion are prepared into a filming base material which is outstanding in weather resistance and water resistance; surface activated fillers are added to improve the corrosion resistance and insulation performance of the coating; the prepared coating paint film is high in attaching force, high in strength, difficult to crack and high in corrosion resistance.

Description

Technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a graphene-added external wall anticorrosive latex paint and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country’s economy, a large amount of steel has been used in fields such as transportation, construction, machinery, energy, chemical industry, infrastructure, railways, and marine development, and the resulting steel corrosion has become more and more serious. Therefore, people have higher and higher performance requirements for anti-corrosion coatings, and traditional organic anti-corrosion coatings can no longer meet the demand. [0003] At present, the exterior wall coatings used in our country mainly use acrylic emulsion as the base material. Water-based acrylic paint has the advantages of moderate cost, excellent weather resistance, good adjustability, and no organic solvent release. It is a type of coat...
