Abstract

The invention discloses a nanometer compound water-based heat insulation anticorrosion paint used for metal and a preparation method thereof. The raw materials of the paint consists of the following components: tap water, watercraft acrylic resin, rustproofing pigment, reflection pigment and filler, hollow micro-beads, watercraft nanometer size, anti-settling agent, wetting and dispersing agent A,wetting and dispersing agent B, film-forming assistant, defoaming agent, flatting agent, anti-flash rustproofing agent and thickening agent. Watercraft polyacrylic emulsion is styrene-crylic acid copolymerization emulsion, pure crylic acid polymerization emulsion or organic silicon-crylic acid copolymerization emulsion. The wetting and dispersing agent A is block macromolecule copolymer, multivalence carboxylate polymer and / or synthetic macromolecule copolymer, and the wetting and dispersing agent B is anion wetting agent and / or nonionic wetting agnet. The product contains no organic solvent,heavy metal and other harmful substances, is extremely excellent in environmental conservation, integrates the functions of anticorrosion and heat insulation as a whole and is simple and convenient for construction, safe in storage and stable in performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nanocomposite water-based heat-insulating and anti-corrosion coating for metals and a preparation method thereof. Background technique [0002] Metal materials will still occupy an important position in the field of materials with their excellent mechanical properties and process properties, but the metal corrosion that occurs all the time has also caused huge losses to human society. Therefore, it is important to develop efficient anti-corrosion coatings to protect them. The most simple and practical method. Storage and transportation equipment, petrochemical equipment, storage roofs and other facilities made of metal materials, on the one hand, will be corroded and damaged by the chemical or electrochemical action of the environmental medium for a long time, on the other hand, they will be unsafe due to heat absorption in summer Hidden dangers, with the development of the g...
