Efficient anticorrosion coating for metal pipes

Abstract

An efficient anticorrosion coating for metal pipes is prepared from raw materials in parts by weight as follows: 12-18 parts of fluorosilicon resin, 4-7 parts of clam shell powder, 8-20 parts of inorganic filler, 2-3 parts of a curing agent, 6-13 parts of a nano oxide particle reinforcing agent, 7-10 parts of flaky aggregate, 5-9 parts of rust resisting pigments, 2-4 parts of a thickener, 8-14 parts of silica powder, 4-7 parts of anti-cracking pigments, 6-10 parts of an organic solvent, 2-4 parts of a coalescing agent, 5-8 parts of phenolic aldehyde modified amine, 13-16 parts of a solvent and 1.5-2.4 parts of magnesium bromide. The efficient anticorrosion coating has the benefits as follows: the efficient anticorrosion coating for the metal pipes has good high-temperature resistance and oxidation resistance and high chemical stability and has a good market prospect, and the preparation process is simplified.

Description

technical field [0001] The invention relates to an efficient anticorrosion coating for metal pipelines. Background technique [0002] Corrosion and rust are one of the main reasons for the damage and failure of metal pipelines. The corrosion of metal pipelines has a great relationship with the environment. The corrosion speed is fast in humid air environments, such as laying pipelines in harsh environments such as polar regions and oceans. , the corrosion reaction is violent and destructive, so its protection puts forward more requirements on the performance of the coating. It is one of the most basic methods for pipeline anticorrosion to evenly and densely coat the surface of the derusted metal pipeline with paint to isolate it from various corrosive media. Today, pipeline anticorrosion coatings are increasingly made of composite materials or composite structures. These materials are required to have good dielectric properties, physical properties, stable chemical propert...
