Problems solved by technology

Ceramic epoxy coatings are generally mixed with polymer epoxy resin, toughening agent, leveling agent, quartz powder and curing agent in a certain proportion. Although this traditional ceramic epoxy coating is widely used, there are also The following disadvantages: Although quartz powder can enhance the adhesion of the coating and improve the mechanical strength of the coating, it is also resistant to corrosion and impact, but its content should not be high, generally below 10%, because the content of quartz is high There is a problem of precipitation, which makes the nozzle blocked and worn during spraying, making it difficult to spray, and the quartz powder cannot be evenly distributed into the paint coating, which reduces the adhesion of the coating, and the coating is easy to fall off, affecting the quality of the coating. Anti-corrosion quality of the coating
And because the content of cheap quartz powder is very low, the cost of ceramic epoxy coating is also very high, which makes its popularization and application very limited.

Abstract

A ceramic-epoxy paint is prepared from components A and B through mixing in ratio of 1:1. Said component A is composed of epoxy resin, levelling agent, quartz powder and anti-depositing agent. Said component B consists of solidifying agent, toughening agent, levelling agent, quartz powder, anti-depositing agent and promoter. Its advantages are not blocking and abrasing nozzle, no deposition, high quality of coated layer, and low cost.

Description

field of invention [0001] The invention relates to the field of chemical anticorrosion, in particular to a ceramic epoxy coating. Background technique [0002] At present, in the field of anticorrosion of underground pipelines at home and abroad, most of the anticorrosion of steel pipes and cast iron pipes are to spray or brush the inner and outer walls with various anticorrosive coatings or paints to form inner and outer anticorrosion layers. Due to the poor anti-corrosion performance of general paints, anti-corrosion paints used for underground pipelines are rare. Among the commonly used anti-corrosion coatings, polymer epoxy resin anti-corrosion coatings are widely used, also known as ceramic epoxy coatings. Ceramic epoxy coatings are generally mixed with polymer epoxy resin, toughening agent, leveling agent, quartz powder and curing agent in a certain proportion. Although this traditional ceramic epoxy coating is widely used, there are also The following disadvantages: ...
