Abstract
The invention discloses a ship metal surface pickling agent. The ship metal surface pickling agent is characterized by being prepared from the following components in parts by weight: 35-48 parts of 0.8mol/L diluted sulphuric acid or diluted hydrochloric acid, 0.9-3.2 parts of thiosemicarbazide, 12-15 parts of carboxyl cellulose salt, 10-12 parts of rosin amine polyoxylethylene ether, 8-15 parts of OP surfactant, 25-35 parts of benzotriazole, 12-15 parts of imidazoline and 5-9 parts of potassium iodide. After the ferric oxide rust on the metal surface is removed by use of the prepared ship metal surface pickling agent, the diluted acid in the pickling agent further reacts with a steel substrate; in order to prevent the diluted acid from over exceeding the metal, the carboxyl cellulose salt, rosin amine polyoxylethylene ether, the OP surfactant and benzotriazole are adopted to change the activation energy of the cathode reaction or the anode reaction of the electrochemical corrosion process, and therefore, the cathode reaction or the anode reaction can be inhibited; thiosemicarbazide, imidazoline and potassium iodide are used for forming a sealing protective film on the steel surface.
Description
Technical field
The present invention relates to a kind of metal protector, be specifically related to a kind of boats and ships metallic surface pickling agent and preparation method thereof.
Background technology
Metal and seawater generation electrochemical reaction and loss and rotten.In seawater, the galvanic corrosion of metal is because the electrochemical nonuniformity of metallic surface causes.This ununiformity can be produced by the change (such as oxygen concentration difference etc.) of medium on metal itself (such as crystal boundary, be mingled with) or metallic surface different sites.Carbon steel is most widely used structured material in exploitation oceanic resources facility.People carried out quite detailed research to carbon steel corrosion behavior in the seawater.Hanging test shows widely, and carbon steel average corrosion rate is in the seawater 0.05-0.13 millimeter/year, and pitting corrosion speed can reach 10 times of average year corrosion rate.The principal element affecting steel corrosion speed is in the seawater the feed speed to steel Surface Oxygen, and also having temperature, flow velocity, fouling organism, calcium carbonate dirt in addition, pollute and the welding, stress etc. of steel construction, is also the influence factor of corrosion speed.So market is in the urgent need to having a kind of metallic surface pickling agent to alleviate corrosion phenomenon.
