Abstract

The present invention discloses a novel rust-conversion coating material with rust. According to the coating material, phosphoric acid, a wetting agent, a dispersing agent, an antifoaming agent, an anti-flashrust agent and a thickener are sequentially added to distilled water, uniform stirring is performed to obtain an intermediate material, a pigment filler is added to the intermediate material, high speed stirring is performed to obtain an auxiliary material, linseed oil, maleic anhydride, a modified phenol formaldehyde resin and a styrene-acrylate emulsion are subjected to adduction to obtain an aqueous resin base material, the auxiliary material is added to the resin emulsion, and uniform stirring and filtering are performed to obtain the rust-conversion coating material with rust. The rust-conversion coating material with rust 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 novel rust-removing coating with rust. Background technique [0002] Building an ecological civilization and basically forming an industrial structure that saves resources and protects the ecological environment is the direction outlined in the report of the Seventeenth National Congress of the Communist Party of my country for the adjustment of China's industrial structure in the next five years. Safety and environmental protection have become the goals pursued by all walks of life. Anti-corrosion coating is a kind of product 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 th...
