Abstract
The present invention relates to one kind of strong acid resistant inner anticorrosive paint and its production process. The paint is produced through adding epoxy resin into mixed solvent one xylene, diacetone alcohol and cyclohexanone; adding phenolic resin, chrome green, precipitated barium sulfate, graphite, PTFE, polyacrylate copolymer solution, polymethyl alkyl siloxane solution and polyamdie wax via mixing; and grinding. The paint may be coated to inner wall of acid gas pipeline and high sulfur matter conveying pipeline for preventing corrosion.
Description
technical field [0001] The invention relates to a strong acid-resistant internal anti-corrosion coating and a manufacturing method, which are used for anti-corrosion of the inner walls of acid gas gathering and transportation pipelines and high-sulfur gathering and transportation pipelines. Background technique [0002] The current development of sour oil and gas fields adopts the method of adding corrosion inhibitors and using anti-sulfur steel for pipeline anti-corrosion. The disadvantages are that it is inconvenient to use and high in cost; Coatings whose coatings have insufficient resistance to strong acids. Contents of the invention [0003] The technical problem to be solved in the present invention is to avoid the disadvantages of the above-mentioned prior art and provide a kind of corrosion resistance to hydrochloric acid and soil acid, which has strong acid resistance, wear resistance and good toughness. Production method. [0004] The technical scheme adopted i...
