Abstract

The invention discloses nano modified elastic paint and a preparation method thereof. The nano modified elastic paint is prepared from a polyurethane acrylate component, a aziridine-terminated polyurethane cross-linking agent and a carbon nano material, wherein the carbon nano material is prepared from the following raw materials in percentage by weight: 4%-6% of graphene, 5%-8% of a carbon nano tube, 3%-8% of carbon nano onions and the balance of an oxidant. The nano modified elastic paint has relatively high elasticity and corrosion resistance, can guarantee long-time adhesion on a buried tube, and has a good application effect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano-modified elastic coating and a preparation method thereof. Background technique [0002] Metal corrosion is the result of chemical or electrochemical reactions between the surface of the metal and the medium in the surrounding environment from the surface to the inside, causing the metal to be damaged and lose its original properties. Buried pipeline is an effective facility for long-distance or short-distance transportation of gas, liquid and slurry materials with minimal impact on the environment. The corrosion process is a naturally occurring process in which iron is transformed into oxides by the action of water and oxygen from the air, so they must be protected from the environment with a suitable corrosion resistant coating throughout their service life. People have studied many measures to prevent and inhibit the corrosion of buried pipelines, among which coating ...
