Abstract

An HCl‑H resistant 2 S corrosion, high temperature resistant coatings, including the following raw materials, 6‑amino‑2‑picolinic acid, graphene nanosheets, organic resins, polyethylene polyamines, trimethylolpropane trimethacrylate, diethylene glycol butyl ether , organosiloxane resin, dispersant, anti-corrosion filler, leveling agent, defoamer, water. Wherein, 6-amino-2-picolinic acid and graphene nanosheets are first esterified to obtain 6-amino-2-picolinic acid graphene ester, and then the organic resin is mixed with polyethylene polyamine and trimethylolpropane Trimethacrylate is reacted to obtain a cross-linked modified organic resin, and finally the obtained 6-amino-2-picolinate graphene ester is functionalized to the cross-linked modified organic resin to obtain 6-amino-2-picolinate graphite Enester functionalized organic resin material, and then mixed with the rest of the components to obtain HCl‑H resistant 2 S corrosion, high temperature resistant coatings.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a HCl-H resistant 2 S corrosion, high temperature resistant coating and preparation method thereof. Background technique [0002] Coatings are often used on the surface of various structural or functional materials to achieve corresponding protective functions. The protective functions of existing coatings are mainly concentrated in common protective fields such as sealing protection, anti-oxidation, anti-corrosion, anti-rust, etc. There is little research on coatings in special protective fields or fields with high protection requirements. [0003] The present invention focuses on the chemical synthesis field and the corresponding chemical product transportation field, such as the hydrochloric acid synthesis and transportation field, the hydrogen sulfide synthesis and transportation field, the oil and gas exploitation and transportation field, and usually requires that the corresponding...
