Abstract

The present invention discloses a weathering resistance rust-conversion coating material with rust. According to the coating material, a rust-conversion agent, a wetting agent, a dispersing agent, an antifoaming agent, an anti-flashrust agent and a thickener are sequentially added to distilled water, and uniform stirring is performed to obtain a first material, wherein the rust-conversion agent comprises 75-80 wt% of phosphoric acid and 20-25 wt% of tannic acid; a pigment filler is added to the first material, and high speed and uniform stirring is performed to obtain a second material; a nature plant polyphosphate, potassium ferrocyanide and an acrylic acid adhesive liquid are subjected to copolymerization preparation synthesis to obtain a resin emulsion; and the resin emulsion and a film forming auxiliary agent are added to the second material, and uniform stirring is performed to obtain the weathering resistance rust-conversion coating material, wherein a weight ratio of the second material to the resin emulsion to the film forming auxiliary agent is 1-3:15-24:0.5-0.75, and the stirring speed is 35-42 r / min. The weathering resistance rust-conversion coating material has characteristics of low environmental pollution, strong weathering aging resistance, strong light aging resistance, and strong chemical corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a weather-resistant and rust-reversing coating. Background technique [0002] Building an ecological civilization and basically forming an industrial structure that saves resources and protects the ecological environment outlines the direction of my country's industrial structure adjustment in the next five years. Safety and environmental protection have become the goals pursued by all walks of life. Anti-corrosion coatings are a class of products with a wide range of uses. Its excellent performance is favored by consumers, but usually solvent-based anti-corrosion coatings are sold on the market. This type of coating requires strict derusting treatment on the surface of the substrate before construction; moreover, this type of coating uses benzene or toluene as a solvent, which evaporates into the air during construction, which not only seriously damages the health of construct...
